DESCRIPTION OF EMBODIMENTS

A specific embodiment of the present invention will be described below with reference to the drawings.

In the embodiment, an example in which an electrically driven vehicle 40 is charged by a charger 2 will be described. However, a charger may be a charger that is able to charge a device for which charging is necessary or may be a charger by which a smartphone, a tablet, or the like is charged. In the embodiment, an electric car will be described as an example of an electrically driven vehicle. The electrically driven vehicle may be a hybrid vehicle, an electrically bicycle, or an electrically driven motorcycle.

As illustrated in FIG. 1, a charger using system 1 includes a plurality of chargers 2 (in FIG. 1, one charger 2 is illustrated representatively), a terminal (first terminal) 31 that is owned by a user 10 using the charger 2, a terminal (second terminal) 32 owned by a person lending an installation place of the charger 2, that is, an owner 20 of the installation place, and a server 4 capable of communicating with the terminals 31 and 32. In the embodiment, the terminals 31 and 32 and the server 4 are configured to be able to communicate with each other via an Internet communication network 30. The terminal 31 and the charger 2 are configured to be able to communicate with each other according to, for example, Bluetooth (BT (registered trademark)) communication or Wi-Fi (registered trademark) which is one wireless communication standard on which a line use fee is not applied.

The charger 2 is a medium-speed charger that outputs, for example, power less than kW and can charge the electrically driven vehicle 40. As an input to the charger 2, direct-current power may be used, alternating-current power of 200 V to 400 V may be used, or direct-current power output from a fuel cell generating hydrogen power may be used. The charger 2 is installed in a pay-by-the hour parking lot or a parking lot of a convenience store or a restaurant all over the country. In the embodiment, the charger 2 is lent for free to the owner 20 from an operating company that operates the charger using system 1.

The terminals 31 and 32 are configured with, for example, tablets, smartphones, personal computers (PCs), or the like. The terminals 31 and 32 each include a first communication unit 301, a second communication unit 302, an operation unit 303, a display unit 304, a speaker 305, and a μCOM 306, as illustrated in FIG. 2. The first communication unit 301 is a communication unit that communicates with the charger 2. The second communication unit 302 is a communication unit connected to the Internet communication network 30. The operation unit 303 performs various operations by the user 10. The display unit 304 displays various types of information. The speaker 305 generates a report sound or the like. The μCOM 306 includes a memory such as a read only memory (ROM), a random access memory (RAM) and a central processing unit (CPU) performing an operation according to a program stored in the memory and is in charge of controlling the terminals 31 and 32.

In the embodiment, an example in which a touch panel is configured by integrating the operation unit 303 and the display unit 304 will be described. In the terminals 31 and 32, a charger using application delivered by an operating company that operates the charger using system 1 is downloaded and stored.

The server 4 includes a second communication unit 41, a DB 42, and a μCOM 43, as illustrated in FIG. 3. The second communication unit 41 is a communication unit for connection to the Internet communication network 30. In the DB 42, registration information (an installation place, an ID (=identification information), an account information of a payee, or the like) or a use situation of the charger 2 and registration information (a name, a vehicle model, a contact, account information of a payee, credit card information, and the like) of the user 10 are stored. In the DB 42, a vehicle map illustrated in FIG. 4 is stored. The vehicle map is a map indicating a relationship between a vehicle model, a battery capacity mounted on an electrically driven vehicle of the vehicle model, and a full charge traveling distance.

In the DB 42, a power unit price map is stored as illustrated in FIG. 5. The power unit price map is a map indicating a relationship between an ID of the charger 2, a use period of time of the charger 2, a commercial power unit price, and a cost power unit price. The commercial power unit price is a power unit price of an electric bill claimed to the user 10 by the operating company and the cost power unit price is a unit price of the electric bill paid to the owner 20 by the operating company. In the embodiment, the cost power unit price is equal to a unit price of the electric bill claimed to the owner 20 by the electric company or the power retail company. For the charger 2 to use cheap power, a power meter different from that of a store may be mounted only for the charger 2 and a contract may be made with a power company or a power retail company different from that of the store so that power of the power retail company different from that of the store can be used. Here, in a unit price of the power retail company with which a contract is made for the charger 2, a cost power unit price is set. The μCOM 43 in charge of controlling the server 4 performs a payment process for a payment fee (=payment price) paid to the owner 20 and performs a claiming process for a claim fee (=claim price) claimed to the user 10.

Next, an operation of the charger using system 1 that have the above-described configuration will be described with reference to FIG. 6. When there is an available charger device 2 and the user 10 desires to use the charger 2, the electrically driven vehicle 40 is connected to the charger 2. Thereafter, the user 10 uses the charger using system 1 to start up a charger using application to use the charger 2.

Accordingly, the μCOM 306 of the terminal 31 (hereinafter abbreviated to a “terminal”) executes the charger using application. The user 10 operates the terminal 31 to set the charger 2 to a use mode. Accordingly, the terminal 31 performs a using process. First, the terminal 31 functions as a first acquisition unit and acquires an ID and output power (kW) of the charger which the user 10 desires to use (Si). In Si, the terminal 31 may acquire the ID and the output power (kW) by communicating with the charger or may read a barcode or a QR code (registered trademark) attached to the charger 2.

Thereafter, the terminal 31 displays an input screen on which use information of the charger 2 is input (S2). An example of the input screen is illustrated in FIG. 7. As illustrated in FIG. 7, the terminal 31 displays an input field C1 in which one of “1. Charge by time,” “2. Charge by distance,” and “3. Full charge” can be selected and input on a touch panel configured with the operation unit 303 and the display unit 304. The terminal 31 displays an input field C2 in which a time can be input when charging by time and displays an input field C3 in which a distance can be input when charging by distance. As apparent from the above, the operation unit 303 and the display unit 304 function as first, second, and third input units.

Subsequently, the terminal 31 acquires a battery capacity and a full charge travelable distance of the electrically driven vehicle 40 desired to be charged (S3). In S3, the terminal 31 requests the battery capacity and the full charge travelable distance from the server 4. When the request is received, the server 4 reads vehicle model information included in registration information associated with an ID of the terminal 31 or a login ID of an application. The server 4 reads a battery capacity (kWh) and a full charge travelable distance (km) corresponding to the vehicle model information read from the vehicle map and transmits the battery capacity (kWh) and the full charge travelable distance (km) to the terminal 31. The terminal 31 can acquire the battery capacity and the full charge travelable distance by receiving the battery capacity (kWh) and the full charge travelable distance (km). The present invention is not limited thereto. The battery capacity and the full charge travelable distance may be stored in the memory of the terminal 31 in registration, and the terminal 31 may read the battery capacity and the full charge travelable distance from the memory so that the battery capacity and the full charge travelable distance can be acquired.

Subsequently, the terminal 31 functions as the second and third acquisition units. An assumed distance of the charge amount by which vehicle can travel when selecting “1. Charge by time” or a charge time taken for the charge when selecting “2. Charge by distance,” and a charge time taken for the charge when selecting “3. Full charge” are calculated and displayed (S4). In S4, the terminal 31 calculates and displays the assumed distance of the charge amount when a time is input to the input field C2 illustrated in FIG. 7. The assumed distance can be calculated by the following Expression (1), for example.

Assumed distance(km)=full charge travelable distance(km)×output power(kW) of charger 2×input time(h)/battery capacity(kWh) (1)

When a distance is input to the input field C3, the terminal 31 calculates and displays a charge time taken for the charge corresponding to the input distance. The charge time when charging by distance can be calculated by the following Expression (2), for example.

Charge time=input distance(km)/full charge travelable distance(km)×battery capacity(kW/h)/output power(kW) of charger (2)

The terminal 31 calculates and displays a charge time when full charge is performed. The charge time when full-charging can be obtained by the following Expression (3), for example.

Charge time={battery capacity (kWh)−remaining capacity (kWh)}/output power (kW) of charger (3)

The remaining capacity (kWh) can be obtained from a battery voltage.

In S4, a charge time for full charging is displayed in the input screen illustrated in FIG. 7. In the input screen, an assumed distance corresponding to the time input in the input field C2 is displayed and a charge time for the distance is displayed in the input field C3. When the user inputs one of 1. to 3. in the input fields with reference to the assumed distance and the charge time and presses a determination button B1 (Y in S5), the terminal 31 functions as first and second transmission units and transmits a use request, the ID of the charger 2, and the use information to the server 4 (S6).

In the embodiment, the use information includes at least a charge time taken for the present charge. More specifically, the use information includes a charge time input to the input field C2 when selecting “1. Charge by time”, includes a charge time for charge corresponding to the input distance calculated by the terminal 31 when selecting “2. Charge by distance”, and includes a charge time until full charge calculated by the terminal 31 when selecting “3. Full charge.”

The μCOM 43 of the server 4 (hereinafter abbreviated to the server 4) functions as the first and second reception units and a fourth acquisition unit and performs a using process illustrated in FIG. 8 when a use request, an ID of a charger, and use information are received from the terminal 31. First, the server 4 calculates a charge power amount taken for the present charge (S21). Specifically, the server 4 calculates the charge power amount using the following Expression (4).

Charge power amount (kWh)=output power (kW) of charger 2×charge time included in use information (4)

Thereafter, the server 4 acquires a commercial power unit price (yen/WHh) corresponding to the charger 2 from the power unit price map (S22). Subsequently, the server 4 functions as a claim fee calculation unit and calculates a claim fee claimed to the user 10 by multiplying a charge power amount (kWh) by the charge power amount (kWh) as expressed in the following Expression (5), for example (S23).

Claim fee=charge power amount(kWh)×commercial power unit price(yen/WHh) (5)

The calculation of the claim fee expressed in Expression (5) is exemplary and the present invention is not limited thereto. As the claim fee, another fee may be further added or a fixed fee may be set regardless of the charge power amount.

The server 4 transmits the calculated claim fee to the terminal 31 (S24). When the claim fee is received (Yin S7 of FIG. 6), the terminal 31 displays the claim fee (S8). When the user 10 checks the claim fee displayed on the terminal 31 and operates a confirmation button (not illustrated) displayed on the terminal 31 (Yin S9), the terminal 31 transmits a confirmation signal to the server 4 (S10), functions as a third transmission unit, and transmits a charge start command to the charger 2 (S11). When the charge start command is received, the charger 2 starts charging.

Thereafter, the terminal 31 starts counting time (S12). When the time reaches the charge time (Yin S13), the terminal 31 functions as the third transmission unit and transmits a charge stop command to the charger 2 (S14). When the charge stop command is received, the charger 2 stops charging. The terminal 31 functions as a first report unit and reports the end of the charge to the user, for example, by outputting a sound or a vibration (S15). Then, the process ends.

Meanwhile, when the confirmation signal is received from the terminal 31 (Y in S25 of FIG. 9), the server 4 performs a claiming process for the calculated claim fee (S26). Specifically, the server 4 claims the claim fee to a bank account of a payee included in the registration information of the terminal 31 or a credit card company. The server 4 stores the claim fee in the DB 42. The server 4 functions as the fourth acquisition unit and acquires a time at which the confirmation signal is received from the terminal 31 as a transmission time of the charge start command.

Subsequently, the server 4 acquires the cost power unit price corresponding to the charger 2 from the power unit price map (S27). Thereafter, the server 4 functions as a payment fee calculation unit. For example, as expressed in the following Expression (6), the server 4 calculates an electric bill paid to the owner 20 by multiplying the charge power amount by the cost power unit price and stores the calculated electric bill in the DB 42 (S28).

Electric bill=charge power amount(kWh)×cost power unit price(yen/kWh) (6)

The server 4 performs a payment process for the owner 20 monthly, for example. The server 4 functions as the payment fee calculation unit and calculates a fee obtained by adding the electric bill stored in the DB 42 and further adding a predetermined charger installation fee. Thereafter, the server 4 transfers a payment fee to a bank account designated by the owner 20. The charger installation fee may be a fixed fee or may increase according to a sold electric amount.

The user 10 can browse a claim fee any time by starting up the charger using application and setting a browse mode. When the user 10 operates the terminal 31, sets the browse mode, and transmits a request for transmitting the claim fee from the terminal 31 to the server 4, the server 4 functions as the claim fee presentation unit, reads a claim fee associated with an ID of the terminal 31 from the DB 42, and transmits the claim fee to the terminal 31. When the claim fee is received, the terminal 31 displays the claim fee on the display unit 304.

The owner 20 can browse the payment fee any time by starting up the charger using application and setting the browse mode. When the owner 20 operates the terminal 32, sets the browse mode, and transmits a request for transmitting the payment fee from the terminal 32 to the server 4, the server 4 reads the payment fee associated with the terminal 32 from the DB 42 and transmits the payment fee to the terminal 32. When the payment fee is received, the terminal 32 displays the payment fee on the display unit 304.

The terminal 31 and the server 4 perform a reservation process illustrated in FIGS. 9 and 10 to reserve the charger 2. In the reservation process, when a confirmation signal is received from the terminal 31 (Y in S31), the server 4 functions as a management unit and performs a management process of managing a use situation of the charger 2 based on the acquired charge time of the charger 2 and a transmission time of the charge start command (S32). More specifically, the server 4 determines that the charger 2 of which the ID is received is not available until the charge time has passed from the transmission time. When the confirmation signal is not received (N in S31), the server 4 moves to S33 immediately.

On the other hand, the user 10 who desires to reserve the charger 2 operates the terminal 31 to switch the mode to a reservation mode. When the mode is switched to the reservation mode, the reservation process is performed and the terminal 31 displays an input screen of a search condition (a present location periphery, a designated location periphery, or the like) of the charger 2 on the touch panel configured with the operation unit 303 and the display unit 304 (S41 of FIG. 10). Accordingly, the operation unit 303 and the display unit 304 function as a fourth input unit. When the user 10 operates the terminal 31 and finishes inputting the search condition on the input screen, a request for transmitting the search condition and the use situation of the charger 2 corresponding to the search condition is transmitted to the server 4 (S42).

When the request for transmitting the search condition and the use situation is received (Y in S33 of FIG. 9), the server 4 searches for the charger 2 according to the search condition and transmits the use situation of the searched charger 2 (S34). When the request for transmitting the search condition and the use situation is not received (N in S33), the server 4 returns to S31. When the use situation is received (S43 of FIG. 10), the terminal 31 functions as a second report unit and displays the use situation (S44). Thereafter, when the user 10 checks the use situation and performs a reservation request operation by designating the charger 2 which is not being used or is not reserved and a reservation time, the terminal 31 transmits the designated charger 2 and a reservation request at the reservation time to the server 4 (S45).

When the reservation request is received (Yin S35 of FIG. 9), the server 4 functions as a reservation processing unit and reserves the designated charger 2 and reservation time (S36). Thereafter, the server 4 transmits a reservation confirmation to the terminal 31 (S37), and returns to S31. When the reservation confirmation is received (Yin S46 of FIG. 10), the terminal 31 ends the process.

According to the above-described embodiment, the server 4 transmits a claim fee in response to a request for transmitting the claim fee from the terminal 31 and transmits a payment fee in response to a request for transmitting the payment fee from the terminal 32. Accordingly, the claim fee is received from the user 10 using the charger 2 and the payment fee can be paid to the owner 20 lending the installation place of the charger 2. Therefore, people lending installation places of chargers can increase and the charger can be widely supplied. According to the above-described embodiment, the payment fee includes an electric bill and a charger installation fee. Accordingly, the payment fee is not lower than the electric bill.

According to the above-described embodiment, the terminal 31 can select and input one of the charge by time, the charge by distance, and the full charge, input a time when charging by time, and input a distance when charging by distance, and acquire a charge time obtained from the input information as use information. Accordingly, it is possible to perform charge fit for the user 10 who desires to use the charger 2.

According to the above-described embodiment, the terminal 31 acquires a charge time of the charger 2, transmits a charge start command to the charger 2, and then transmits a charge end command to the charger after the charge time has passed. Accordingly, it is possible to control the charger 2 using the terminal 31.

According to the above-described embodiment, the terminal 31 reports the transmission of the charging end command to the user 10. Accordingly, it is possible to prevent the charger 2 from being in the use state despite the end of the charge.

According to the above-described embodiment, the server 4 acquires a charge time of the charger 2 and a transmission time of the charge start command through communication with the terminal 31, manages the use situation of the charger 2 based on the acquired charge time and transmission time of the charge start command, and performs a reservation process for an available charger through communication with the terminal 31. Accordingly, the server 4 can manage the use situation of the charger 2 and make a reservation through communication with the terminal 31.

According to the above-described embodiment, the terminal 31 inputs a search condition, communicates with the server 4, and acquires and displays a use situation of the charger corresponding to the input search condition. Accordingly, the server 4 can manage the use situation of the charger 2 and report the use situation to other terminals 31 through communication with the terminal 31 using the charger 2. That is, as long as the terminal 31 can be operated and the use situation of the charger 2 can be acquired even during using the charger 2 in a store or the like, it can be known how soon the charge ends. The terminal 31 can be operated to make a reservation after the charge ends.

The present invention not limited to the above-described embodiment and modifications, improvements, or the like can be made appropriately. Any material, dimension, number, disposition location, and the like of each constituent in the above-described embodiment can be used and is not limited as long as the present invention can be embodied.

According to the above-described embodiment, the terminal 31 calculates the charge time when selecting charge by distance and full charge, but the present invention is not limited thereto. The terminal 31 may transmit a distance input in the input field C3 or a battery voltage as use information to the server 4, and the server 4 may calculate a charge time based on the use information and transmit the calculated charge time to the terminal 31.

According to the above-described embodiment, one of charge by time, charge by distance, and full charge can be selected using the terminal 31, but the present invention is not limited thereto. For example, only full charge may be able to be performed.

According to the above-described embodiment, the terminal 31 counts the charge time and transmits the charge end command to the charger 2, but the present invention is not limited thereto. The charger 2 may acquire a charge time through communication with the terminal 31 or the server 4, and the charger 2 may count the charge time, and the charge may automatically end.

According to the above-described embodiment, money is claimed or paid as a claim price or a payment price, but the present invention is not limited thereto. As the claim price or the payment price, points may be claimed or paid.

When it is a reservation time, the server 4 may transmit, to the terminal 31, the fact that it is the reservation time, and the terminal 31 may report that it is the reservation time. The server 4 may cancel the reservation when a charge request cannot be received from the reserved terminal 31 although it is the reservation time.
