Movable body rescue system, server, and movable body rescue method
A depleted EV transmits first information including a current location of the depleted EV to a server. Each of the other vehicles transmits second information including a current location of the vehicle to the server. When the server receives from the depleted EV a help signal requesting power supply from another vehicle to the depleted EV, the server selects, from among the other vehicles, a rescue EV to supply electric power to the depleted EV, using the first information and the second information.
1. A movable body rescue system comprising:
a first movable body equipped with a first power storage device storing electric power for traveling;
a plurality of second movable bodies each equipped with a second power storage device storing electric power for traveling; and
a server configured to communicate with the first movable body and the plurality of second movable bodies, wherein
the first movable body is configured such that the first power storage device can be charged by receiving electric power from any one of the plurality of second movable bodies,
each of the plurality of second movable bodies is configured to supply electric power stored in the second power storage device to the first movable body,
the first movable body is configured to transmit first information including a current location of the first movable body to the server,
each of the plurality of second movable bodies is configured to transmit second information including a current location of the second movable body to the server, and
when the server receives from the first movable body a help signal requesting power supply from any one of the plurality of second movable bodies to the first movable body, the server is configured to select, from among the plurality of second movable bodies, a power-supplying movable body to supply electric power to the first movable body, using the first information and the second information.
2. The movable body rescue system according to claim 1 , wherein
each of the plurality of second movable bodies is configured to transmit to the server a signal indicating whether or not the second movable body can supply electric power to the first movable body, and
when the server receives the help signal from the first movable body, the server is configured to select, using the first information and the second information, the power-supplying movable body from among second movable bodies each indicating by the signal its ability to supply electric power to the first movable body.
3. The movable body rescue system according to claim 1 , wherein
when the server receives the help signal from the first movable body, the server is configured to select, using the first information and the second information, a second movable body closest to the first movable body of the plurality of second movable bodies as the power-supplying movable body.
4. The movable body rescue system according to claim 1 , wherein
the second information includes a stored power amount of the second power storage device,
when the server receives the help signal from the first movable body, the server is configured to select, from among the plurality of second movable bodies, a second movable body storing a prescribed and required power amount in the second power storage device as the power-supplying movable body, and
the required power amount is calculated from the stored power amount of the second power storage device, and a power amount that allows travel from a location of power supply to the first movable body to power supply equipment capable of charging the second power storage device.
5. A server comprising a communication device configured to communicate with a first movable body and a plurality of second movable bodies, the first movable body being equipped with a first power storage device storing electric power for traveling, the plurality of second movable bodies each being equipped with a second power storage device storing electric power for traveling, wherein
the first movable body is configured such that the first power storage device can be charged by receiving electric power from any one of the plurality of second movable bodies,
each of the plurality of second movable bodies is configured to supply electric power stored in the second power storage device to the first movable body,
the communication device is configured to
receive first information including a current location of the first movable body from the first movable body, and
receive, from each of the plurality of second movable bodies, second information including a current location of the second movable body, and
the server further comprises a processor configured to perform a process of selecting, from among the plurality of second movable bodies, a movable body to supply electric power to the first movable body, using the first information and the second information, and
the processor is configured to perform the process when the server receives, from the first movable body through the communication device, a help signal requesting power supply from any one of the plurality of second movable bodies to the first movable body.
6. A movable body rescue method used in a system including a first movable body, a plurality of second movable bodies, and a server configured to communicate with the first movable body and the plurality of second movable bodies, wherein
the first movable body is equipped with a first power storage device storing electric power for traveling, and is configured such that the first power storage device can be charged by receiving electric power from any one of the plurality of second movable bodies,
each of the plurality of second movable bodies is equipped with a second power storage device storing electric power for traveling, and is configured to supply electric power stored in the second power storage device to the first movable body, and
the rescue method comprises
transmitting first information including a current location of the first movable body from the first movable body to the server,
transmitting, from each of the plurality of second movable bodies, second information including a current location of the second movable body to the server, and
when the server receives from the first movable body a help signal requesting power supply from any one of the plurality of second movable bodies to the first movable body, selecting, from among the plurality of second movable bodies, a movable body to supply electric power to the first movable body, using the first information and the second information.
