The present application claims priority to Japanese Patent Application No. JP 2010-120921, filed in the Japanese Patent Office on May 26, 2010, the entire contents of which is being incorporated herein by reference.
In recent years, a technology called smart grid has been gaining attention. The smart grid is a technological framework to realize efficient power usage by constructing a new transmission network having a communication channel along with the transmission network and using this intelligent transmission network. The background idea of the smart grid is to realize efficient management of the amount of power use, swift handling of an incident when such an incident occurs, remote control of the amount of power use, distributed power generation using power generation facilities outside the control of a power company, or charging management of an electric vehicle. Particularly, effective utilization of in-house power generating stations using renewable energy by ordinary households or operators other than power companies and charging management of various electric vehicles typically including electric cars have been attracting considerable attention. Incidentally, renewable energy is energy generated without using fossil fuel.
Power generated by ordinary households or operators other than power companies is used by power generation operators. Remaining power after use by the power generation operators is currently purchased by power companies. However, purchasing power supplied from power generation facilities outside the control of a power company is a heavy burden to the power company. For example, amount of power supplied from photovoltaic power generation facilities depends on the weather. Moreover, amount of power supplied from in-house power generating stations of ordinary households depends on power use of ordinary households that largely changes day by day. Thus, it is difficult for power companies to receive stable power supply from power generation facilities outside the control of power companies. For the above reason, it may become difficult for power companies to purchase power in the future.
Thus, a home battery initiative that uses power generated by power generation facilities outside the control of power companies after temporarily storing the power in batteries has recently been gaining attention. For example, a method of using power generated by photovoltaic power generation facilities by storing such power in batteries and making up for shortages in the night or when the weather is bad is considered. Furthermore, a method of limiting amount of power received from a power company in accordance with the battery storage amount or using power stored in batteries in the daytime when power rates are higher by storing power, in batteries, supplied by a power company in the night when power rates are lower are considered. Also, batteries can store power as DC, which makes DC/AC conversion or AC/DC conversion during transmission unnecessary so that losses during conversion can be reduced.
Thus, various expectations regarding power management mingle with one another amid the smart grid initiative. To realize such power management, the smart grid initiative is premised on having a communication channel along with a transmission network. That is, exchanging information about power management by using this intelligent transmission network is assumed (see JP-A-2002-354560, for example). However, in a region where a communication infrastructure is already built, instead of using a transmission network as a communication channel, information about power management may be exchanged by using a network constructed by the deployed communication infrastructure. That is, what is important in the smart grid initiative is how to efficiently manage power generation facilities and storage facilities that are not uniformly managed.
In the smart grid initiative described above, it is extremely important to efficiently gather a variety of information including the power storage states of power storage apparatuses and to provide the gathered information to the user in an easily comprehendible manner. However, a method of doing so is yet to be proposed.
In light of the foregoing, it is desirable to provide an information processing apparatus, an information processing method, a program, and a power storage apparatus management system which are capable of efficiently gathering a variety of information including the power storage states of power storage apparatuses and providing the gathered information to the user in an easily comprehendible manner.

By operating the various types of operation terminals given above, the user is also able to carry out operation control over a specified power storage apparatus 20 via the information processing apparatus 10 according to the present example embodiment.
The information processing apparatus 10 acquires and manages log information expressing operation states of the power storage apparatuses 20 that has been transmitted from the power storage apparatuses 20 and, in accordance with requests from the user operation terminals 9, provides various information relating to the power storage apparatuses that are being managed to the user operation terminals 9. In other words, the information processing apparatus 10 according to the present example embodiment can be thought of as a power storage apparatus management server that manages the power storage apparatuses 20 and also as an information providing server that provides information relating to the power storage apparatuses 20 to the user operation terminals 9.
The information processing apparatus 10 is also capable of providing various information relating to the power storage apparatuses 20 being managed to various servers, such as a search server or an information providing server, that are connected to the communication network 7. It is also possible for a search server, an information providing server, or the like that is connected to the communication network 7 to be equipped with the functions of the information processing apparatus 10 according to the present example embodiment.
The configuration of the information processing apparatus 10 according to the present example embodiment will now be described again in more detail.
A power storage apparatus 20 is an apparatus that is equipped with a battery and is capable of storing power acquired from a power generating apparatus 30 or a power supplying network 40 and supplying stored power to various appliances that use power. The power storage apparatus 20 is also capable when excess power is held to sell such excess power via a power supplying network 40 to a power supplying company.
Each power storage apparatus 20 according to the present example embodiment has a function that is capable of carrying out communication using the mobile communication network 3. Each power storage apparatus 20 according to the present example embodiment is also capable of acquiring data such as GCA and RMC outputted from a GPS (Global Positioning System) and specifying the installed position at which such apparatus is installed. As described below, each power storage apparatus 20 according to the present example embodiment transmits log information including GPS data and various information showing the state of the power storage apparatus 20 via the mobile communication network 3 to the information processing apparatus 10 according to the present example embodiment.
The configuration of a power storage apparatus 20 according to the present example embodiment will now be described.

Here, a photovoltaic power generating device, a wind power generating device, a geothermal power generating device, a hydroelectric power generating device, a wave power generating device, and the like can be given as examples of a power generating device that generates power using renewable energy. The power generating apparatus 30 may be a power generating device that generates electricity using non-renewable energy that has a lower environmental footprint than thermal power generation or the like where gasoline, coal, or the like is burned to generate power. Here, a fuel cell, a natural gas-driven generating device, a biomass power generating device and the like can be given as examples of such a power generating device.
A power supplying network 40 is power supplying equipment that supplies power generated by equipment owned by a power supplying company.
This completes the overall description of the configuration of the power storage apparatus management system 1 according to the present example embodiment.
Next, the configuration of the information processing apparatus 10 according to the present example embodiment will be described in detail with reference to
As shown in
The mobile communication unit 101 is realized by a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), a modem for communicating with the mobile communication network 3, and the like. The mobile communication unit 101 controls the communication carried out between the information processing apparatus 10 and a power storage apparatus 20 via the mobile communication network 3. When the processing units provided in the information processing apparatus 10 according to the present example embodiment exchange information with a power storage apparatus 20, the transmitting and receiving of such information is carried out via the mobile communication unit 101.
As one example, the communication unit 103 is realized by a CPU, a ROM, a RAM, a communication apparatus, and the like. The communication unit 103 controls communication carried out between the information processing apparatus 10 and a user operation terminal 9 via the communication network 7. When the processing units provided in the information processing apparatus 10 according to the present example embodiment exchange information with a user operation terminal 9, the transmitting and receiving of such information is carried out via the communication unit 103. Also, when the processing units of the information processing apparatus 10 transmit and receive information via the communication network 7 such as the Internet to or from another apparatus such as various servers connected to the communication network 7, the transmitting and receiving of such information is carried out via the communication unit 103.
As one example, the registration unit 105 is realized by a CPU, a ROM, a RAM, and the like. The registration unit 105 registers users who make use of the management function for power storage apparatuses 20 provided by the information processing apparatus 10 according to the present disclosure and the power storage apparatuses 20 themselves owned by such users.
As one example, the user registration unit 121 is realized by a CPU, a ROM, a RAM, and the like. When a user has operated a user operation terminal 9 to make a request to the information processing apparatus 10 to join a management service for a power storage apparatus 20, the user registration unit 121 registers information relating to the user in question in a database stored in the storage unit 111, described later. At this time, the user registration unit 121 assigns a unique user ID to the user and manages various information (hereinafter referred to as “user information”) relating to the user.
Note that when user registration is carried out, the user registration unit 121 may use a known encryption technique, digital signature technique, or the like to issue various data, such as an encryption key or a digital signature for ensuring the validity of a user, to a user operation terminal 9 owned by the user.
Also, if the information processing apparatus 10 according to the present example embodiment is capable of connecting to a public server such as a search server connected to the communication network 7, it is also possible for user information registered in the public server to be used as the user information of the information processing apparatus 10 according to the present example embodiment.
As one example, the power storage apparatus registration unit 123 is realized by a CPU, a ROM, a RAM, and the like. When there is a power storage apparatus 20 that has been newly connected to the power storage apparatus management system 1 according to the present example embodiment, the power storage apparatus registration unit 123 registers information relating to such power storage apparatus 20 in a database stored in the storage unit 111, described later. When doing so, the power storage apparatus registration unit 123 assigns a unique ID to each power storage apparatus and manages various information (hereinafter referred to as “registered appliance information”) relating to the power storage apparatus.
Although there are no particular limitations on the flow by which the power storage apparatus registration unit 123 registers a power storage apparatus 20 that has been newly connected to the system, as one example the power storage apparatus registration unit 123 may register a power storage apparatus 20 using the flow described below. One example of the flow of a registration process for a power storage apparatus will now be described in brief with reference to
When a new power storage apparatus 20 is connected to the power storage apparatus management system 1 according to the present example embodiment, the connected power storage apparatus 20 transmits registration information including at least the information listed below via the mobile communication network 3 to the information processing apparatus 10.
When the registration information described above has been acquired via the mobile communication unit 101, the power storage apparatus registration unit 123 registers the acquired registration information in the database as registered appliance information. Also, by carrying out an action such as separately transmitting a message to user operation terminals 9, the power storage apparatus registration unit 123 associates the power storage apparatus 20 that has been newly connected to the system with a user. By doing so, registered appliance information such as that shown in
In the registered appliance information shown in
Note that although the registered appliance information shown in
Note that when a new power storage apparatus 20 has been registered, the power storage apparatus registration unit 123 may use a known encryption technique, digital signature technique, or the like to issue various data, such as an encryption key or a digital signature for ensuring the validity of a power storage apparatus, to the power storage apparatus 20 that has been newly registered.
This completes the description of the registration unit 105 according to the present example embodiment. The explanation will now return to
As one example, the power storage apparatus management unit 107 is realized by a CPU, a ROM, a RAM, and the like. The power storage apparatus management unit 107 is a processing unit that manages the power storage apparatuses 20 based on various information acquired from the power storage apparatuses 20 via the mobile communication network 3. In other words, the power storage apparatus management unit 107 is a processing unit for realizing various functions in order to manage the power storage apparatuses 20 registered in the information processing apparatus 10.
As one example, the log information acquiring unit 131 that is one example of an information acquiring unit is realized by a CPU, a ROM, a RAM, and the like. The log information acquiring unit 131 acquires power storage apparatus information that was transmitted from a power storage apparatus and received by the mobile communication unit 101. Such power storage apparatus information is the log information showing the installed position and operation state of a power storage apparatus 20 over time. As one example, such log information is transmitted to the information processing apparatus 10 with the timing described below by communication via the mobile communication network 3 that has been established from the power storage apparatus 20 side.
In addition to the situations described above, log information may be transmitted from a power storage apparatus 20 to the information processing apparatus 10 in the situations listed below.
One example of the power storage apparatus information (hereinafter also referred to as “log information”) transmitted from a power storage apparatus 20 is shown in
On acquiring log information such as that illustrated in
As one example, the information management unit 133 is realized by a CPU, a ROM, a RAM, and the like. The information management unit 133 refers to the log information acquired by the log information acquiring unit 131 and manages the content of a database (in more detail, the registered appliance information) registered in the storage unit 111. When doing so, the information management unit 133 manages the content of the database by associating such content with time/date information expressing the time and date when the log information was acquired. By doing so, the information management unit 133 is capable of grasping changes over time in the content written in the registered appliance information, and it becomes possible to provide information showing changes over time in the state of the power storage apparatus 20 to the user as necessary.
As one example, the information providing unit 135 is realized by a CPU, a ROM, a RAM, and the like. In accordance with an information disclosure request from a user operation terminal 9 operated by a user, the information providing unit 135 provides the managed registered appliance information to the user operation terminal 9 that made the request.
Although the information provided by the information providing unit 135 to the user operation terminal 9 may be set as appropriate, as examples it is possible to provide information that graphically shows the operation state of the power storage apparatus 20, information that shows the location of the power storage apparatus 20 on a map, setting conditions of the power storage apparatus 20, and the like. Note that because it is possible to display the location of the power storage apparatus 20 on a map using GPS information, when the power storage apparatus 20 has been stolen, it is also possible to display the present location and/or the movement route of the power storage apparatus 20 on a map.
When providing the registered appliance information, the information providing unit 135 should preferably convert the registered appliance information to be provided to a user operation terminal 9 to a data format that can be displayed by the user operation terminal 9 and then provide the converted information via the communication unit 103 to the user operation terminal 9.
For example, when the user operation terminal 9 is a device that is capable of using a Web browser, the information providing unit 135 converts the information to be provided to the user to a data format (for example, a format such as HTML or XML) that is capable of being displayed using a Web browser. When the applications that can be used by the user operation terminal 9 are limited, such as when the user operation terminal 9 is some type of mobile appliance or a car navigation system, the information providing unit 135 converts the data format of the information in accordance with the applications that can be used.
The information providing unit 135 is also capable of changing the content of the registered appliance information to be provided to the user operation terminal 9 in accordance with a user operation carried out on the user operation terminal 9.
Note that the information providing unit 135 is capable of providing information relating to a power storage apparatus 20 not only to a user operation terminal 9 but also to various types of server, such as a search server, or another information processing apparatus connected to the communication network 7. Although the information providing unit 135 is capable of selecting the information on the power storage apparatus 20 to be provided to another server or information processing terminal, as one example, by providing information expressing the installed position of the power storage apparatus 20, it becomes possible to confirm the installed state of the power storage apparatus 20 from an arbitrary server.
As one example, the control information generating unit 137 is realized by a CPU, a ROM, a RAM, and the like. When setting information relating to operation of a power storage apparatus 20 transmitted from a user operation terminal 9 has been stored in a specified location such as the storage unit 111, the control information generating unit 137 uses the stored setting information to generate control information for controlling the power storage apparatus 20. When a connection has been established with the power storage apparatus 20 in question using the mobile communication network 3, the control information generating unit 137 transmits the generated control information via the mobile communication unit 101 to the power storage apparatus 20.
There are no particular limitations on the type of control information generated by the control information generating unit 137 and such information may be set as appropriate. Note that because it is possible in the power storage apparatus management system 1 according to the present example embodiment for the information processing apparatus 10 to grasp information expressing the installed position of a power storage apparatus 20, by setting in advance a region in which the power storage apparatus 20 can operate, it would be conceivably possible to prevent theft of the power storage apparatus 20.
The control information generating unit 137 is capable of executing a generation process for control information for controlling the power storage apparatus 20 at arbitrary timing. As examples, the control information generating unit 137 may generate the control information when setting information is stored in a specified location and/or when a connection has been established with the power storage apparatus 20 in question.
Once the generated control information has been transmitted to the power storage apparatus 20 in question, the control information generating unit 137 should preferably request the information management unit 133 to update the content of the registered appliance information to a content in keeping with the control information.
This completes the detailed description of the functions of the power storage apparatus management unit 107 according to the present example embodiment with reference to
As one example, the setting information acquiring unit 109 is realized by a CPU, a ROM, a RAM, and the like. When a setting changing screen for a power storage apparatus 20 has been operated at a user operation terminal 9 that has been provided with information from the information providing unit 135 and the operation settings of the power storage apparatus 20 have been changed, the setting information acquiring unit 109 acquires setting conditions showing the changed operation settings from the user operation terminal 9. The setting information acquiring unit 109 stores the setting conditions acquired from the user operation terminal 9 as setting information in a specified location of the storage unit 111. When communication has been established with the power storage apparatus 20 in question using such setting information, the control information generating unit 137 of the power storage apparatus management unit 107 transmits control information generated based on the setting information to the power storage apparatus 20.
The storage unit 111 is one example of a storage apparatus provided in the information processing apparatus 10 according to the present example embodiment. Various databases, namely user information relating to users who use the power storage apparatus management system according to the present example embodiment and registered appliance information relating to power storage apparatuses connected to the power storage apparatus management system, are stored in the storage unit 111. Various history information may also be recorded in the storage unit 111. In addition, the information processing apparatus 10 according to the present example embodiment records various parameters that may need to be stored when carrying out some kind of processing, intermediate results of processing, various databases, programs, and the like as appropriate in the storage unit 111.
The storage unit 111 is capable of being freely read and written by the various processing units provided in the information processing apparatus 10.
One example of the functions of the information processing apparatus 10 according to the present example embodiment has been described above. The various component elements described above may be configured using general-purpose parts and circuits or may be configured using hardware that is dedicated to the functions of the respective component elements. Alternatively, the functions of the respective component elements may all be carried out by a CPU or the like. Accordingly, it is possible to change the configuration in use as appropriate in accordance with the prevailing technical level when implementing the present example embodiment.
Note that a computer program for realizing the functions of the information processing apparatus according to the above example embodiment may be created and installed in a personal computer or the like. It is also possible to provide a computer-readable recording medium on which such a computer program is stored. As examples, the recording medium may be a magnetic disk, an optical disc, a magneto-optical disc, or a flash memory. The computer program mentioned above may also be distributed via a network, for example, without using a recording medium.
Note that although the information processing apparatus 10 according to the present example embodiment has been described by way of an example where the flow that associates the power storage apparatuses 20 to users is carried out having first carried out a registration process relating to users who use the system, the present disclosure is not limited to this example. For example, users that are able to use the respective power storage apparatuses 20 may be associated with the power storage apparatuses 20 after the power storage apparatuses 20 to be managed have first been registered in the information processing apparatus 10 according to the present example embodiment. In other words, in the information processing apparatus 10 according to the present example embodiment, so long as the power storage apparatuses 20 recorded in the information processing apparatus 10 and information relating to users that are able to carry out various operations on such power storage apparatuses 20 are correctly associated, such associating can be carried out according to any processing flow.
Next, the configuration of a power storage apparatus according to the present example embodiment will be described in brief with reference to
As shown in
The battery B stores power generated by a power generating apparatus 30 and/or power supplied from the power supplying network 40 and supplies the stored power to a power using appliance 50, such as an electrical appliance or an electric vehicle. Although there are no particular limitations on the configuration of the battery B itself, as one example it is possible to use a lithium ion battery or the like as the battery B.
The mobile communication unit 201 is realized by a CPU, a ROM, a RAM, a modem for communicating with the mobile communication network 3, and the like. The mobile communication unit 201 controls communication carried out between the power storage apparatus 20 and the information processing apparatus 10 via the mobile communication network 3. When the various processing units provided in the power storage apparatus 20 according to the present example embodiment exchange information with the information processing apparatus 10, such information is transmitted and received via the mobile communication unit 201.
Here, when the mobile communication unit 201 exchanges information with the information processing apparatus 10, a connection is established in a direction from the mobile communication unit 201 on the power storage apparatus 20 side toward the information processing apparatus 10 (that is, the mobile communication unit 201 on the power storage apparatus 20 side is the initiator). By doing so, the mobile communication unit 201 is capable of establishing a connection with the information processing apparatus 10 in a state that is suited to transmission of information by the power storage apparatus 20.
Note that as described earlier, the exchanging of information between the information processing apparatus 10 and the power storage apparatus 20 is carried out via the mobile communication network 3. For this reason, to suppress the number of transmitted packets and power usage required to transmit and receive information, the mobile communication unit 201 is capable of using various communication methods.
As one example, the battery management unit 203 is realized by a CPU, a ROM, a RAM, various sensors for grasping the state of the battery B, and the like. The battery management unit 203 monitors the state of the battery B provided in the power storage apparatus 20 and grasps the state of the battery B. The battery management unit 203 is capable of using information obtained by grasping the state of the battery B to grasp a drop in the functioning of the battery B, failure of the battery B, and the like. As examples, as the method of grasping a drop in the functioning of the battery B, failure of the battery B, and the like, it is possible to use a known method, such as a method that makes judgments using specified thresholds or a method that uses a discriminant function generated according to a heuristic method.
The battery management unit 203 outputs information obtained by grasping the state of the battery B to the log information generating unit 209, described later, to transmit the information to the information processing apparatus 10 according to the present example embodiment.
The battery management unit 203 also changes various setting information relating to operation of the power storage apparatus 20 in accordance with control information for the power storage apparatus 20 transmitted from the information processing apparatus 10.
In addition, the battery management unit 203 is capable of realizing various functions carried out to cause the power storage apparatus 20 to operate appropriately in addition to the functions described above.
As one example, the power supplying control unit 205 is realized by a CPU, a ROM, a RAM, and the like. The power supplying control unit 205 supplies power stored in the battery B to a power using appliance 50 such as an electrical appliance or an electrical vehicle in accordance with instructions from the battery management unit 203. If the selling of power stored in the power storage apparatus 20 is recognized, the power supplying control unit 205 is also capable of selling stored power via the power supplying network 40.
As one example, the GPS data acquiring unit 207 is realized by a CPU, a ROM, a RAM, various sensors for receiving GPS signals, and the like. By receiving a plurality of signals transmitted from GPS satellites, the GPS data acquiring unit 207 calculates position information showing the present position on the globe. The GPS data acquiring unit 207 outputs position information relating to the present position calculated based on signals transmitted from GPS satellites to the log information generating unit 209 as GPS data. Here, there are no particular limitations on the timing at which signals transmitted from GPS satellites are received and such reception can be carried out at arbitrary timing. As one example, the log information generating unit 209 is realized by a CPU, a ROM, a RAM, and the like. When the timing at which the log information is transmitted to the information processing apparatus 10 has been reached, the log information generating unit 209 generates the log information based on the various information acquired from the battery management unit 203 and the GPS data acquiring unit 207. The content of the generated log information is as shown in
Here, as the timing at which the log information generating unit 209 generates the log information, aside from when the power storage apparatus 20 is newly connected to the power storage apparatus management system 1, the following timing could conceivably be used.
Timing at which the log information is generated (aside from when newly connecting to the system)
In addition to the situations described above, the log information generating unit 209 may generate log information in the situations listed below.
As one example, the control information acquiring unit 211 is realized by a CPU, a ROM, a RAM, and the like. The control information acquiring unit 211 enquires to the information processing apparatus 10 as to whether there is control information for the power storage apparatus 20 to which the control information acquiring unit 211 belongs, and acquires control information for controlling the power storage apparatus 20 that has been transmitted from the information processing apparatus 10 via the mobile communication network 3. The acquisition of control information is carried out when a connection has been established via the mobile communication network 3 for transmission of the log information generated by the log information generating unit 209 to the information processing apparatus 10.
On acquiring the control information transmitted from the information processing apparatus 10 via the mobile communication unit 201, the control information acquiring unit 211 outputs the acquired control information to the battery management unit 203. By carrying out operation control of the power storage apparatus 20 based on the control information outputted by the control information acquiring unit 211, the battery management unit 203 is capable of realizing the operation control over the power storage apparatus 20 intended by the user.
The storage unit 213 is one example of a storage apparatus provided in the power storage apparatus 20 according to the present example embodiment. Various information, such as the log information itself transmitted by the power storage apparatus 20 and history information relating to transmission of the log information, is stored in the storage unit 213. In addition, the power storage apparatus 20 according to the present example embodiment also records various parameters that may need to be stored when carrying out some kind of processing, intermediate results of processing, various databases, programs, and the like as appropriate in the storage unit 213.
The storage unit 213 is capable of being freely read and written by the various processing units provided in the power storage apparatus 20.
One example of the functions of the power storage apparatus 20 according to the present example embodiment has been described above. The various component elements described above may be configured using general-purpose parts and circuits or may be configured using hardware that is dedicated to the functions of the respective component elements. Alternatively, the functions of the respective component elements may all be carried out by a CPU or the like. Accordingly, it is possible to change the configuration in use as appropriate in accordance with the prevailing technical level when implementing the present example embodiment.
Next, the flow of the information processing method according to the present example embodiment will be described in brief with reference to
Note that it is assumed that user registration relating to users who use the power storage apparatus management system 1 according to the present example embodiment and appliance registration of the power storage apparatuses 20 connected to the power storage apparatus management system 1 have been completed before the following explanation begins.
When a user wishes to know the operation state of a power storage apparatus 20, the user operates a user operation terminal 9 the user has to cause the user operation terminal 9 to connect to the information processing apparatus 10 using an ordinary Internet connection or the like (step S101). At this time, a specified log-in process is implemented between the user operation terminal 9 and the information processing apparatus 10 (step S103). This log-in process may be a log-in process that is unique to the power storage apparatus management system 1 according to the present example embodiment or may use a log-in process for a public information providing server, an information searching server, or the like.
Once the log-in process is complete and the validity of the user operating the user operation terminal 9 has been confirmed, the information providing unit 135 of the information processing apparatus 10 refers to a database (the registered appliance information) stored in the storage unit 111. After this, the information providing unit 135 provides the power storage apparatus information for the power storage apparatus 20 whose operation state the user wishes to grasp to the user operation terminal 9 in a suitable format for the user operation terminal 9 (step S105).
Also, when the user has operated the user operation terminal 9 and changed the setting information that designates operation settings of the power storage apparatus 20, the user operation terminal 9 transmits the changed setting information to the information processing apparatus 10 (step S107). Once the setting information transmitted from the user operation terminal 9 has been acquired, the setting information acquiring unit 109 of the information processing apparatus 10 stores the acquired setting information in a specified location in the storage unit 111 or the like (step S109).
When the user has finished viewing the information relating to the power storage apparatus 20 currently in focus, the user operates the user operation terminal 9 and carries out a specified log out process (step S111). By doing so, the connection established between the user operation terminal 9 and the information processing apparatus 10 is released.
After this, in the power storage apparatus 20 connected to the power storage apparatus management system 1, when the timing for transmitting the log information to the information processing apparatus 10 has been reached, the log information generating unit 209 of the power storage apparatus 20 starts to generate the log information to be transmitted (step S121). When doing so, the log information generating unit 209 acquires information to be written in the log information, that is, information relating to the operation state of the battery when the log information is generated, from the battery management unit 203. The log information generating unit 209 also acquires GPS data (position information) expressing the present position of the power storage apparatus 20 from the GPS data acquiring unit 207. Based on such acquired information and setting information that sets what information is to be included in the log information, the log information generating unit 209 generates the log information to be transmitted to the information processing apparatus 10.
Also, in the power storage apparatus 20, when the log information generating unit 209 starts to generate the log information, the establishment of a connection via the mobile communication network 3 to be used for communication with the information processing apparatus 10 is commenced (step S123). The protocol used for communication with the information processing apparatus 10 can be decided as appropriate.
When a connection with the information processing apparatus 10 has been established, the power storage apparatus 20 requests the information processing apparatus 10 to transmit a main instruction (step S125). The power storage apparatus management unit 107 of the information processing apparatus 10 transmits a main instruction indicating the transmission of log information to the power storage apparatus 20 (step S127).
The log information generating unit 209 of the power storage apparatus 20 receives the main instruction transmitted from the information processing apparatus 10 (a main instruction indicating the transmission of log information) and transmits the generated log information to the information processing apparatus 10 (step S129).
When the acquisition of the log information transmitted from the power storage apparatus 20 has been completed, the log information acquiring unit 131 of the information processing apparatus 10 notifies the power storage apparatus 20 that synchronization of the log information has been completed (step S131). The information management unit 133 of the information processing apparatus 10 also updates the content of the registered appliance information stored in the storage unit 111 based on the acquired log information.
The control information acquiring unit 211 of the power storage apparatus 20 enquires to the information processing apparatus 10 as to whether there is control information for the power storage apparatus 20 to which the control information acquiring unit 211 belongs, and requests transmission of the control information when such control information exists (step S133). The power storage apparatus management unit 107 of the information processing apparatus 10 confirms whether control information exists for the power storage apparatus 20 with which a connection has been established and transmits the stored control information to the power storage apparatus 20 when such control information exists (step S135). When reception of the control information transmitted from the information processing apparatus 10 has been completed, the control information acquiring unit 211 of the power storage apparatus 20 notifies the information processing apparatus 10 that reception has been completed (step S137). The control information acquiring unit 211 outputs the received control information to the battery management unit 203. By doing so, it is possible for the battery management unit 203 to start control of the battery based on new control information.
On receiving notification that reception has been completed, the information processing apparatus 10 starts to disconnect the connection on the mobile communication network 3 that was established with the power storage apparatus 20 (step S139). By doing so, the connection on the mobile communication network 3 that was initiated from the power storage apparatus 20 side is released.
In this way, according to the information processing method according to the present example embodiment, by operating a user operation terminal 9, a user who is capable of referring to the state of a power storage apparatus 20 is able to confirm the state of such power storage apparatus 20 from any location and is also able to remotely operate the power storage apparatus 20.
In the power storage apparatus management system 1 according to the present example embodiment, communication between the information processing apparatus 10 and the power storage apparatus 20 is realized by a connection made via the mobile communication network 3. This means that control information for a power storage apparatus 20 set by a user operation is transmitted to such power storage apparatus 20 when a connection is established with the power storage apparatus 20. Meanwhile, because it is possible for the power storage apparatus 20 to acquire control information stored in the information processing apparatus 10 at the timing when log information is transmitted to the information processing apparatus 10, it is possible to suppress the amount of communicated data and consumed battery power required for communication without the connection with the information processing apparatus 10 having to be maintained.
Note that although the case where a connection via the mobile communication network 3 is initiated from the power storage apparatus 20 to the information processing apparatus 10 has been described above, the connection via the mobile communication network 3 may be initiated from the information processing apparatus 10 side.
Next, examples of information providing screens provided by the information processing apparatus 10 according to the present example embodiment will be described with reference to
When a user of the power storage apparatus management system 1 operates a user operation terminal 9 and connects to the information processing apparatus 10, a display screen (“information providing screen”) such as that shown in

Aside from such display regions, the information providing screen is also provided with a display region that displays a location of the power storage apparatus based on GPS data, a display region for images taken by webcams mounted on the power storage apparatus, and a display region for comments made by users relating to the power storage apparatus. As one example, maintenance information and the like relating to the power storage apparatus 20 is displayed in the display region for comments.
By referring to such an information providing screen, the user can easily grasp information relating to a power storage apparatus 20 over which the user has authority at timing desired by the user.
By operating the user operation terminal 9, the user is capable of having a display screen such as that shown in
In addition, by operating the user operation terminal 9, the user is capable of having a display screen such as that shown in

This information providing screen is generated on the user operation terminal 9 mainly by the functioning of the power storage apparatus management unit 107 (in more detail, by the information providing unit 135) of the information processing apparatus 10.
By operating the user operation terminal 9 and having a setting screen such as that shown in
For example, by operating the display region in which operation contents for operating the power storage apparatus from a remote location are displayed, the user is capable of realizing a remote operation over the power storage apparatus. In the example shown in
Also, in the display region in which contents for carrying out maintenance are displayed, it is possible to indicate rebooting the power storage apparatus, a start of a self-diagnosis process for the power storage apparatus, an update process for various software that runs on the power storage apparatus, and the like.
In addition, in the display region for setting operations during an emergency, it is possible to indicate an emergency halting of the power storage apparatus and make settings as to whether to implement an anti-theft mode, such as whether to sound a siren when the power storage apparatus is stolen.
By operating the user operation terminal 9 and having a setting screen such as that shown in
By operating the display region for setting the frequency for transmitting log information, the user is able to set the frequency for transmitting log information to the information processing apparatus 10. By operating the display region for selecting the various information included in the log information, the user is able to set the content of the log information transmitted by a power storage apparatus (and moreover, the content of the information that can be confirmed by the user himself/herself in an information providing screen). By changing such contents, the user is able to freely customize the amount of transmitted information and consumed battery power relating to the transmission of log information.
Also, by operating the display region for setting events, it is possible to change the event settings, i.e., in what situations the log information is transmitted. By operating the display region for setting the operation schedule, the user is able to set an operation schedule, i.e., a time period during the day where the charging (or discharging) is to be carried out. By operating the display region for setting measures to be taken when the power storage apparatus is stolen, the user is able to make a setting of in what situations the operation of the power storage apparatus is to stop automatically and a setting of in what situations an alert (warning) is to be issued.
