The present invention relates to a vehicle charging system, a parking lot system, and a vehicle charging method. In particular, it relates to a vehicle charging system, a parking lot system, and a vehicle charging method for performing non-contact charging on batteries mounted on vehicles.
In recent years, methods for performing non-contact charging on batteries mounted on vehicles have been discussed. For example, PTLs 1 to 3 disclose configurations in which charging is performed by disposing a non-contact charging apparatus on a road surface or a parking lot and moving a vehicle to a charging space where this charging apparatus is disposed. For example, PTL 1 discloses a configuration that enables charging on a vehicle 2 during parking by disposing, on a bottom surface of the vehicle 2, a power receiving part 21 that receives power from a power feeding part 31 embedded in a road surface of a parking space 3 through electromagnetic induction.
PTL 4 discloses a configuration in which parking rights are checked by, instead of having a parking lot attendant check parking tickets, previously registering captured images of license plates and corresponding parking areas associated with each other in a database and checking the database for the correspondence between a parking area and a license plate.
PTL 1: Japanese Patent Kokai Publication No. JP2010-226945A
PTL 3: Japanese Patent Kokai Publication No. JP2013-34369A
PTL 4: Japanese Patent Kokai Publication No. JP2015-179531A
The following analysis has been given by the present inventor. According to the charging systems in PTLs 1 to 3, when a user charges a vehicle, the user does not need to insert a charging plug into the charging port on the vehicle body. However, the user needs to get out of his/her vehicle, to prove to a charging apparatus that the user has the right to receive a charging service, and this is considered as a problem. In this wired charging service using a charging plug, an individual user is requested to pay the cost of charging by an integrated circuit (IC) card or a credit card.
For example, PTL 4 proposes a parking fee payment method. However, in the case of non-contact charging, in view of the cost of a charging facility, a method in which a charging space is provided separately from a parking area has been proposed. Thus, the content in PTL 4 cannot directly be applied, which is considered as a problem.
It is an object of the present invention to provide a vehicle charging system, a parking lot system, and a vehicle charging method that contribute to improving convenience of a charging system in which a plurality of vehicles are charged by using a non-contact charging apparatus as described above.
According to a first aspect, there is provided a vehicle charging system including a non-contact charging apparatus that performs non-contact charging on a battery of a vehicle by facing a power receiving coil mounted on the vehicle. This vehicle charging system further includes: an information acquisition part configured to acquire, from the vehicle, information for determining whether to allow charging on the vehicle; and a charging control part configured to control a charging operation of the charging apparatus based on information acquired by the information acquisition part.
According to a second aspect, there is provided a parking lot system including: a non-contact charging apparatus that performs non-contact charging on a battery of a vehicle by facing a power receiving coil mounted on the vehicle; an information acquisition part configured to acquire, from the vehicle, information for determining whether to allow charging on the vehicle; a charging control part configured to control a charging operation of the charging apparatus based on information acquired by the information acquisition part; and a vehicle movement part configured to move a vehicle that has been charged from a place where the charging apparatus is installed.
According to a third aspect, there is provided a vehicle charging method including: causing a charging control apparatus, which is included in a vehicle charging system including a non-contact charging apparatus that performs non-contact charging on a battery of a vehicle by facing a power receiving coil mounted on the vehicle and an information acquisition part configured to acquire, from the vehicle, information for determining whether to allow charging on the vehicle, to acquire, from the vehicle, information for determining whether to allow charging on the vehicle; and causing the charging control apparatus to control a charging operation of the charging apparatus based on the acquired information. This method is associated with a certain machine, i.e., a vehicle charging system that performs non-contact charging on a plurality of vehicles.
The meritorious effects of the present invention are summarized as follows.
The present invention can improve convenience of a charging system in which vehicles are charged by using a non-contact charging apparatus as described above.
First, an outline of an exemplary embodiment of the present disclosure will be described with reference to a drawing. Reference characters in the following outline denote various elements for the sake of convenience and are used as examples to facilitate understanding of the present disclosure. Namely, the reference characters are not intended to limit the present disclosure to the illustrated modes. An individual connection line between blocks in any of the drawings used in the following description signifies both one-way and two-way directions. An individual arrow schematically illustrates the principal flow of a signal (data) and does not exclude bidirectionality. In addition, although there are ports or interfaces at the connection points of the input and output of each block in the figures, they are omitted.
As illustrated in
More specifically, the information acquisition part 12 acquires, from the vehicle, information for determining whether to allow charging on the vehicle. Any information can be used as the information for determining whether to allow charging. For example, information indicating users of a non-contact charging service using the charging apparatus 11 may be used. This information acquisition part 12 can simply be realized by an apparatus (a bar code reader or a radio frequency identification (FRID) communication apparatus) that reads a bar code or an RFID attached to a part of the body of an individual vehicle. Alternatively, a device having a wireless communication function such as iBeacon and Eddystone using Bluetooth Low Energy (BLE) may be attached to the body of the vehicle, and the information acquisition part 12 may be configured to acquire information for determining whether to allow charging from this device (“BlueTooth”, “iBeacon”, and “Eddystone” are registered trademarks).
The charging control part 13 controls an operation of the charging apparatus 11 based on the information acquired by the information acquisition part 12. Specifically, the charging control part 13 gives the charging apparatus 11 an instruction for allowing or denying charging on the vehicle. By adopting the above configuration, the driver of the vehicle can receive a charging service without getting out of his/her vehicle.
In the present description, the term “acquisition” includes active acquisition and passive acquisition. Active acquisition signifies a case in which an apparatus acquires data or information stored in a different apparatus or a storage medium. Examples of the case include a case in which an apparatus transmits a request or a query to a different apparatus and receives data or information from the different apparatus and a case in which an apparatus accesses a different apparatus or a storage medium and reads out data or information. Passive acquisition includes at least one of a case in which data or information outputted from a different apparatus is inputted to an apparatus (passive reception) and a case in which an apparatus receives distributed (or transmitted, push-notified, etc.) data or information. In addition, the active acquisition includes a case in which an apparatus selectively acquires data or information of all the data received thereby, and the passive acquisition includes a case in which an apparatus selectively receives distributed data or information.
Next, a first exemplary embodiment of the present disclosure will be described in detail with reference to drawings.
The charging apparatus 11 is a non-contact charging apparatus that performs non-contact charging on a battery of a vehicle by facing a power receiving coil (a charging port) mounted on the vehicle. The non-contact charging method is not particularly limited. For example, an electromagnetic induction method or a resonance method may be used. When the resonance method is used, power is transmitted from a power transmitting coil included in the charging apparatus 11 to the power receiving coil by coupled resonance (resonance) between a circuit having the power transmitting coil and a circuit having the power receiving coil. More specifically, for example, a power-transmitting resonance circuit is formed with a capacitor in the circuit having the power transmitting coil, and a power-receiving resonance circuit is formed with a capacitor in the circuit having the power receiving coil. The same resonance frequency is set between the power transmitting circuit and the power receiving circuit so that coupled resonance is produced between the power-transmitting resonance circuit and the power-receiving resonance circuit at this frequency. In this way, the charging apparatus 11 can transmit power to the vehicle without bringing the power transmitting coil and the power receiving coil to mechanically come into contact with each other.
The user DB 14 is a database that holds information about users of a charging service using the above non-contact charging apparatus 11. In the present exemplary embodiment, information stored in the user DB 14 illustrated in
As the information acquisition part 12, for example, a reading device that captures an image of a license plate of a vehicle that has stopped at a position where the charging apparatus 11 can perform charging and reads information about the license plate of the vehicle from the captured image can be used. For example, an optical character reader (OCR) can be used as the above device.
When the charging control part 13 receives license plate information from the information acquisition part 12, the charging control part 13 checks whether the corresponding license plate is registered in the user DB 14 illustrated in
Next, an operation according to the present exemplary embodiment will be described in detail with reference to a drawing.
Next, the information acquisition part 12 transmits the read license plate information to the charging control part 13 (step S002; acquisition of information).
After receiving the information, the charging control part 13 checks whether the corresponding license plate is registered in the user DB 14 (step S003). As a result of the checking, if the corresponding license plate is registered in the user DB 14 (Yes in step S004), the charging control part 13 instructs the charging apparatus 11 to perform a charging operation (step S005).
In accordance with the instruction from the charging control part 13, the charging apparatus 11 starts to perform the charging operation on the vehicle (step S006). In step S004, if the corresponding license plate is not registered in the user DB 14 (No in step S004), the charging control part 13 does not instruct the charging apparatus 11 to perform the charging operation.
As described above, according to the present exemplary embodiment, a highly convenient configuration can be achieved. Namely, whether to allow charging on a vehicle can be determined by using the license plate information of the vehicle. In addition, according to the present exemplary embodiment, since the user does not need to actually operate the charging apparatus 11 to prove that the user has the right to receive the charging service, the body of the charging apparatus 11 can be downsized. In addition, the charging apparatus 11 can be installed at various places.
In the above exemplary embodiment, while the license plate information is used as the information for determining whether to allow charging, various kinds of information may be used as the information for determining whether to allow charging. For example, a bar code, an identification plate, an IC card, or an RFID, in which information indicating that a corresponding user is a subscriber of the charging service is recorded, may be attached to a side or bottom surface of a vehicle, and the information acquisition part 12 may be configured to read the information. Alternatively, in place of the configuration using the above dedicated medium, an image of a vehicle, an image of a user, or a feature amount obtained from these images may be used.
Next, a second exemplary embodiment obtained by changing the above first exemplary embodiment will be described in detail with reference to drawings.
The information acquisition part 12a acquires two or more kinds of information as the information for determining whether to allow charging. While a plurality of information acquisition parts 12a are arranged in the example in
Thus, the information acquisition part 12a acquires tag information obtained from an RFID, in addition to the above license plate information.
Next, if each item of information received from the information acquisition part 12a is registered in the user DB 14, charging control part 13 instructs a charging apparatus 11 to perform a charging operation.
In addition to the advantageous effects provided by the above first exemplary embodiment, the second exemplary embodiment of the present disclosure can provide an advantageous effect of preventing unauthorized provision of a charging service, which could occur otherwise if the first authentication information is forged or stolen.
In addition, while the tag information obtained from an RFID has been used as the second authentication information in the above description, information usable as the first authentication information described above may be used in combination with the license plate information. For example, as illustrated in
Next, a third exemplary embodiment obtained by changing the above second exemplary embodiment will be described in detail with reference to a drawing.
Charging control part 13 according to the present exemplary embodiment also serves as second information acquisition part configured to acquire charging condition information and determines whether each item of information received from information acquisition part 12a is registered in the user DB 14 and whether a corresponding condition(s) set as the field “charging condition” is satisfied. For example, in the case of a user A in
For example, in the case of a user B in
In addition to the advantageous effects provided by the above first and second exemplary embodiments, the third exemplary embodiment of the present disclosure can provide an advantageous effect of providing a finer charging service. Since the charging conditions illustrated in
In addition, execution of a user approval operation and a user authentication operation before the start of charging may be used as a charging condition. In this way, unintended charging, e.g., charging on a stolen vehicle, can be prevented. In particular, since charging on a stolen vehicle is prevented, even is a vehicle is stolen, the stolen vehicle can only travel with the amount of electricity charged at that point.
In addition, in the third exemplary embodiment, it is preferable that individual users be able to freely update their own charging conditions in the user DB 14. In addition, it is also preferable that combinations of charging conditions be set as templates and that a user interface, with which the users can select a template as needed, be prepared.
Next, a fourth exemplary embodiment will be described in detail with reference to drawings. In the fourth exemplary embodiment, information obtained from information acquisition part 12 is used as information for determining whether a vehicle exists in a charging space, and, after a vehicle is charged, the user of the vehicle is notified of the completion of the charging.
As illustrated in
When receiving the notification of the completion of the charging, the charging control part 13 records a predetermined value (for example, “1”), which indicates the completion of the charging, in a corresponding entry in the user DB 14, the entry being under the charging completion flag field (step S102). If the charging completion flag corresponding to a vehicle represents the predetermined value indicating the completion of charging and if the charging control part 13 still keeps receiving the information for determining whether to allow charging from the information acquisition part 12 (steps S103 and S104), the charging control part 13 reads contact information (a mail address) of the corresponding user from the user DB 14 (step S105; check DB).
Next, the charging control part 13 creates a charging completion notification addressed to the read contact information (the mail address) and transmits the notification thereto (step S106).
In addition to the advantageous effects provided by the above first and second exemplary embodiments, the fourth exemplary embodiment of the present disclosure can provide an advantageous effect of notifying individual users of the completion of their charging. In addition, since users are expected to move their vehicles promptly when receiving the above notifications, the utilization rate of the charging apparatus 11 can be improved. Of course, information about an incentive for moving their vehicles, information about billing, information about a penalty for not moving their vehicles, etc. may be included in the charging completion notifications. In addition, if the charging control part 13 keeps receiving the information for determining whether to allow charging from the information acquisition part 12 for a predetermined time after the transmission of a charging completion notification, namely, if a vehicle is still occupying the charging space, the charging completion notification may be transmitted again.
While mail addresses are used as the contact information about the users in the example in
Next, a fifth exemplary embodiment will be described in detail with reference to drawings. The fifth exemplary embodiment further includes a function of moving vehicles that have been charged.
A motor that can move a pallet or the like on which a vehicle is mounted can be used as the vehicle movement part 16. As a different mode of the vehicle movement part, a pallet-less type vehicle moving mechanism that exchanges a vehicle by using comb-teeth arms may alternatively be used, instead of pallet-type vehicle movement part. The destination of the vehicle may be a parking space dedicated for vehicles that has been charged, for example.
As illustrated in
After receiving the notification of the completion of the charging, if the charging control part 13 still keeps receiving the information for determining whether to allow charging from the information acquisition part 12 (steps S102 and S103), the charging control part 13 determines that the vehicle needs to be moved and instructs the vehicle movement part 16 to move the vehicle (step S106; control of movement of vehicle).
In addition to the advantageous effects provided by the above first and second exemplary embodiments, the fifth exemplary embodiment of the present disclosure can provide an advantageous effect of improving the utilization rate of the charging apparatus 11 by promptly moving an individual vehicle that has been charged from the installation place of the charging apparatus 11.
While an individual vehicle that has been charged is moved in the fifth exemplary embodiment, the following variation (a sixth exemplary embodiment) may be used for a mechanical parking facility. As illustrated in
In addition, each of the functional part of the vehicle charging systems used in the above exemplary embodiments may be realized by a computer program which causes a computer that constitutes the corresponding vehicle charging system to use its hardware and perform corresponding processing described above.
While exemplary embodiments of the present invention have thus been described, the present invention is not limited thereto. Further variations, substitutions, or adjustments can be made without departing from the basic technical concept of the present invention. For example, the configurations of the networks, the configurations of the elements, and the representation modes of the messages illustrated in the drawings have been used only as examples to facilitate understanding of the present invention. Namely, the present invention is not limited to the configurations illustrated in the drawings
