The motor controller, the brake controller, and the battery controller may be replaced with separate control devices, respectively, for example, control devices including a motor ECU, a brake ECU, a battery ECU, and the like.
The motor controller controls the motor 12 based on an output of the vehicle sensor 20. The brake controller controls the brake device 16 based on an output of the vehicle sensor 20. The battery controller calculates a battery charge rate of the battery 40 based on an output of the battery sensor 42 attached to the battery 40 and outputs the calculation result of the battery charge rate of the battery 40 to the power supply/reception requester 38 and the display device 60. The power supply/reception requester 38 acquires the calculation result of the battery charge rate of the battery 40 output by the battery controller.
The power supply/reception requester 38 acquires the acquired calculation result of the battery charge rate of the battery 40 and periodically creates battery charge rate notification information including the acquired calculation result of the battery charge rate and the user ID destined for the power supply/reception matching device 100. The power supply/reception requester 38 outputs the created battery charge rate notification information to the communication device 50.
When the user U of the vehicle 200 performs an operation to request power reception on the operator 80 of the vehicle 200, the operator 80 outputs an operation signal including information of the request for power reception (which will be referred to as a “power reception request signal” below) to the power supply/reception requester 38.

The battery sensor 42 detects, for example, a current value, a voltage value, and a temperature of the battery 40. The battery sensor 42 outputs battery use status information including the detected current value, voltage value, temperature, and the like to the controller 36. The battery sensor 42 may include a plurality of sensors including current sensors, voltage sensors, temperature sensors, and the like. If the battery sensor 42 includes a plurality of sensors, battery use status information may include battery sensor identifiers. Each battery sensor identifier is an identifier with which the plurality of sensors included in the vehicle 200 can be identified. The battery sensor identifiers may be represented by, for example, predetermined alphanumeric characters.
The communication device 50 includes a wireless module to be connected to the Internet, a WAN, a LAN, a public line, a provider device, a dedicated line, a radio base station, or the like.
The communication device 50 acquires the battery charge rate notification information, the power reception request, and the power supply request output from the power supply/reception requester 38 and transmits the acquired battery charge rate notification information, power reception request, and power supply request to the power supply/reception matching device 100 via the network NW shown in
The communication device 50 receives notification information transmitted from the power supply/reception matching device 100 via the network NW. The communication device 50 outputs the received notification information to the display device 60.
The display device 60 includes, for example, a display 62 and a display controller 64. The display 62 displays information according to control of the display controller 64. The display controller 64 causes the display 62 to display a battery charge rate according to information output from the vehicle sensor 20. The display controller 64 causes the display 62 to display a matching processing result (a list of power supplying vehicles and a power receiving vehicle) and the like according to information output from the communication device 50. Returning to
The power supply/reception matching device 100 is realized by a device such as a personal computer, a server, an industrial computer, or the like. The power supply/reception matching device 100 includes, for example, a communicator 110, an acquirer 120, a matching processor 130, a guider 140, and a storage 160.
The communicator 110 is realized by a communication module. Specifically, the communicator 110 is configured by a device that performs wired communication. The communicator 110 may be configured by a wireless device that performs wireless communication using a wireless communication technology such as LTE or a wireless LAN. The communicator 110 communicates with the terminal device 300 and the communication device 50 included in the vehicle 200 via the network N. Specifically, the communicator 110 receives a power reception request or a power supply request transmitted by the terminal device 300 and outputs the received power reception request or power supply request to the acquirer 120. The communicator 110 receives battery charge rate notification information transmitted by the communication device 50 of a vehicle 200 and outputs the received battery charge rate notification information to the acquirer 120. The communicator 110 receives a power reception request transmitted by the communication device 50 of a vehicle 200 and outputs the received power reception request to the acquirer 120. The communicator 110 receives a power supply request transmitted by the communication device 50 of a vehicle 200 and outputs the received power supply request to the acquirer 120. The communicator 110 acquires notification information output by the guider 140 and transmits the acquired notification information to the terminal device 300.
The storage 160 may be realized by a hard disk drive (HDD), a flash memory, a random access memory (RAM), a read only memory (ROM), or the like. The storage 160 stores user information 162 and battery-related information 164. The user information 162 and the battery-related information 164 may be stored in a cloud.
The user information 162 is a table format information in which user IDs, information indicating request details, battery type information, and information for identifying battery charge rates (%) are associated with each other.
This information is stored based on a power reception request transmitted from a power receiving vehicle.
The user information 162 stores a user ID “0002,” information indicating request details “power supply,” battery type information “BBBB,” and information for identifying a battery charge rate (%) “YY” associated with each other. This information is stored based on a power supply request transmitted from a power supplying vehicle. The user information 162 stores a user ID “0003,” information indicating request details “−,” battery type information “CCCC,” and information for identifying a battery charge rate (%) “ZZ” associated with each other. This information is stored based on battery charge rate notification information periodically transmitted by a vehicle 200. Because the battery charge rate notification information does not include information indicating that power reception or power supply is requested, request details are not stored.
The battery-related information 164 is table format information in which battery type information, information indicating a material of a corresponding battery, information indicating a material of a battery that can receive power, and information indicating a material of a battery that can supply power are associated. A material of a battery that can receive power refers to a material of the positive electrode of the battery, and examples thereof include LiyNiO2, LiyCoO2, LiyV2O5, LiyFePO4, LiyMn2O4, Li(1-y)Mn2O4, LiyTiS2, LiyWO3, NayCoO2, and the like.
The acquirer 120, the matching processor 130, and the guider 140 are realized by a hardware processor, for example, a central processing unit (CPU), or the like, executing a program (software) saved in the storage 160. Some or all of these functional units may be realized by hardware (a circuit unit including circuitry) such as a large-scale integration (LSI), an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or a graphics processing unit (GPU) or may be realized by cooperation of software with hardware. The program may be saved in a storage device (a storage device with a non-transitory storage medium) such as a hard disk drive (HDD) or a flash memory in advance, or may be saved in a detachable storage medium (a non-transitory storage medium) such as a DVD or a CD-ROM, and may be installed when a storage medium is loaded into a drive device.
The acquirer 120 acquires battery charge rate notification information output by the communicator 110, associates the user ID, the battery type information, and the information for identifying a battery charge rate included in the acquired battery charge rate notification information, and registers the associated information in the user information 162 of the storage 160.
When the acquirer 120 acquires a power reception request output by the communicator 110 and the acquired power reception request includes the user ID and the information indicating a request for power reception and does not include the battery type information and information for identifying a battery charge rate, the acquirer registers “power reception” in the request details associated with the user ID in the information included in the user information 162 of the storage 160. The acquirer 120 outputs information including the user ID and indicating that the power reception has been requested (which will be referred to as “power reception request information” below) to the matching processor 130.
When the acquirer 120 acquires a power supply request output by the communicator 110 and the acquired power supply request includes the user ID and the information indicating a request for power supply and does not include the battery type information and information for identifying a battery charge rate, the acquirer registers “power supply” in the request details associated with the user ID in the information included in the user information 162 of the storage 160. The acquirer 120 outputs information including the user ID and indicating that the power supply has been requested (which will be referred to as “power supply request information” below) to the matching processor 130.
When the acquirer 120 acquires a power reception request output by the communicator 110 and the acquired power reception request includes the user ID, the information indicating a request for power reception, the battery type information, and the information for identifying a battery charge rate, the acquirer updates the information associated with the user ID in the information included in the user information 162 of the storage 160. The acquirer 120 outputs the power reception request information including the user ID and indicating that the power reception has been requested to the matching processor 130.
When the acquirer 120 acquires a power supply request output by the communicator 110 and the acquired power supply request includes the user ID, the information indicating a request for power supply, the battery type information, and the information for identifying a battery charge rate, the acquirer updates the information associated with the user ID in the information included in the user information 162 of the storage 160. The acquirer 120 outputs the power supply request information including the user ID and indicating that the power supply has been requested to the matching processor 130.
The acquirer 120 may delete information for which a predetermined period of time has passed out of the registered information.
The matching processor 130 matches a power receiving vehicle to a power supply vehicle based on the information registered in the user information 162 of the storage 160 and the information stored in the battery-related information 164. By matching the power receiving vehicle to the power supplying vehicle, the matching processor 130 selects the vehicle that can supply power to the power receiving vehicle. In other words, the matching processor 130 selects the vehicle to which the power supplying vehicle can supply power.
Because the system voltage of the vehicle 200-a is higher than the system voltage of the vehicle 200-b, power can be supplied from the vehicle 200-a to the vehicle 200-b.
Because the system voltage of the vehicle 200-a is lower than the system voltage of the vehicle 200-c, power can be supplied from the vehicle 200-c to the vehicle 200-a. In other words, the vehicle 200-a is a target receiving power from the vehicle 200-c.
Because the system voltage of the vehicle 200-b is lower than the system voltage of the vehicle 200-c, power can be supplied from the vehicle 200-c to the vehicle 200-b.
The vehicle 200-d is a vehicle in which a voltage controller (VCU) is mounted. The VCU is, for example, a DC-DC converter which boosts electric power supplied from the battery and outputs the electric power to a DC link DL. For this reason, the vehicle 200-d can receive and supply power from and to the vehicle 200-a to the vehicle 200-c. In the present embodiment, description will be continued on a case in which a vehicle 200 is not equipped with a VCU. A case in which a battery charge rate is used, instead of a system voltage will be continuously described. In other words, whether power supply is possible is determined based on a comparison result of battery charge rates.
