Abstract

Claims (55)

1 . A control device comprising a processor configured to:

acquire electric power supply information indicating suppliable electric energy by each of a plurality of vehicles and electric power demand information indicating demanded electric energy of a facility to which each of the vehicles supplies electric power;

fix a master vehicle that controls electric power supply of each of the vehicles from among the vehicles based on the electric power supply information;

control electric energy when each of the vehicles supplies the electric power to the facility based on the electric power supply information of the master vehicle and the electric power demand information;

acquire vehicle model information indicating a vehicle model of each of the vehicles;

determine whether each of the vehicles is provided with an electric power generation function using predetermined fuel based on the vehicle model information;

acquire a remaining amount of the predetermined fuel from the vehicle provided with the electric power generation function; and

fix the master vehicle based on the remaining amount and the electric power supply information.

2 . The control device according to claim 1 , wherein the processor:

determines whether the remaining amount is equal to or less than a threshold value for each of the vehicles provided with the electric power generation function; and

outputs instruction information for instructing refueling of the fuel to the vehicle that is provided with the electric power generation function and for which the remaining amount is determined as equal to or less than the threshold value.

3 . The control device according to claim 2 , wherein the processor executes control to, when any of the vehicles provided with the electric power generation function stops electric power supply to the facility, increase electric energy supplied by the master vehicle so as to supplement electric energy supplied by the vehicle that is provided with the electric power generation function and that stops the electric power supply to the facility.

4 . The control device according to claim 3 , wherein the processor:

determines whether a new vehicle is connected to the facility; and

executes control to adjust the electric energy supplied by the master vehicle and electric energy supplied by the new vehicle to the facility when the processor determines that the new vehicle is connected to the facility.

5 . The control device according to claim 4 , wherein the processor executes control to reduce the electric energy supplied by the master vehicle to electric energy immediately after the electric power supply to the facility is started and increase the electric energy supplied by the new vehicle to the facility after a certain period of time has elapsed.

6 . The control device according to claim 3 , wherein the control device:

determines whether any of the vehicles provided with the electric power generation function stops the electric power supply to the facility; and

starts electric power supply to the facility by driving an external power source when the control device determines that the any of the vehicles provided with the electric power generation function stops the electric power supply to the facility.

7 . The control device according to claim 6 , wherein the processor executes control to adjust the electric energy supplied by the master vehicle to the facility and electric energy supplied by the external power source to the facility when the external power source starts the electric power supply to the facility.

8 . The control device according to claim 1 , wherein the processor:

determines whether the master vehicle stops electric power supply to the facility; and

fixes a new master vehicle from among the vehicles based on the electric power supply information when the processor determines that the master vehicle stops the electric power supply to the facility.

9 . The control device according to claim 1 , wherein the processor fixes the vehicle in which the remaining amount is the largest as the master vehicle.

10 . The control device according to claim 1 , wherein:

the control device is implemented in at least one of the vehicles; and

the processor acquires the electric power supply information in accordance with a predetermined wireless communication standard.

11 . A server comprising a processor configured to:

acquire electric power supply information indicating suppliable electric energy by each of a plurality of vehicles and electric power demand information indicating demanded electric energy of a facility to which each of the vehicles supplies electric power;

fix a master vehicle that controls electric power supply of each of the vehicles from among the vehicles based on the electric power supply information;

control electric energy when each of the vehicles supplies the electric power to the facility based on the electric power supply information of the master vehicle and the electric power demand information;

acquire vehicle model information indicating a vehicle model of each of the vehicles;

determine whether each of the vehicles is provided with an electric power generation function using predetermined fuel based on the vehicle model information;

acquire a remaining amount of the predetermined fuel from the vehicle provided with the electric power generation function; and

fix the master vehicle based on the remaining amount and the electric power supply information.

12 . The server according to claim 11 , wherein the processor:

determines whether the remaining amount is equal to or less than a threshold value for each of the vehicles provided with the electric power generation function; and

outputs instruction information for instructing refueling of the fuel to the vehicle that is provided with the electric power generation function and for which the remaining amount is determined as equal to or less than the threshold value.

13 . The server according to claim 12 , wherein the processor executes control to, when any of the vehicles provided with the electric power generation function stops electric power supply to the facility, increase electric energy supplied by the master vehicle so as to supplement electric energy supplied by the vehicle that is provided with the electric power generation function and that stops the electric power supply to the facility.

14 . The server according to claim 13 , wherein the processor:

determines whether a new vehicle is connected to the facility; and

executes control to adjust the electric energy supplied by the master vehicle and electric energy supplied by the new vehicle to the facility when the processor determines that the new vehicle is connected to the facility.

15 . The server according to claim 14 , wherein the server executes control to reduce the electric energy supplied by the master vehicle to electric energy immediately after the electric power supply to the facility is started and increase the electric energy supplied by the new vehicle to the facility after a certain period of time has elapsed.

16 . The server according to claim 13 , wherein the server:

determines whether any of the vehicles provided with the electric power generation function stops the electric power supply to the facility; and

starts electric power supply to the facility by driving an external power source when the server determines that the any of the vehicles provided with the electric power generation function stops the electric power supply to the facility.

17 . The server according to claim 16 , wherein the processor executes control to adjust the electric energy supplied by the master vehicle to the facility and electric energy supplied by the external power source to the facility when the external power source starts the electric power supply to the facility.

18 . A non-transitory storage medium storing a program that causes a processor to:

acquire electric power supply information indicating suppliable electric energy by each of a plurality of vehicles and electric power demand information indicating demanded electric energy of a facility to which each of the vehicles supplies electric power;
