Information providing system and method, and server used for information providing system and method
An information providing system includes a plurality of vehicle, a charging station, and a management server. The management server is configured to communicate with the plurality of vehicles and the charging station. Each of the vehicles allows charging of a power storage device mounted therein using electric power from the charging station and performs inter-vehicle charging for charging another vehicle using electric power of the power storage device. The management server obtains a congestion degree in the charging station and a destination of a vehicle. When a charging station is installed as an annex at a destination of the vehicle, and when the congestion degree exceeds a threshold value, the management server selects a candidate vehicle capable of performing inter-vehicle charging from among other vehicles that aim at a destination identical to the destination of the vehicle, and transmits information about the selected candidate vehicle to the vehicle.
1. A server configured to communicate with
a plurality of vehicles each equipped with a power storage device and
a charging station configured to supply electric power,
each of the plurality of vehicles being configured to
allow charging of the power storage device using electric power from the charging station, and
perform inter-vehicle charging for charging another vehicle using electric power of the power storage device,
the server being configured to
obtain a congestion degree in the charging station based on information from the charging station,
obtain a destination of each of the plurality of vehicles,
when the charging station is installed as an annex at a destination of a first vehicle included in the plurality of vehicles, and when the congestion degree in the charging station exceeds a threshold value, select at least one of candidate vehicles each permitting the inter-vehicle charging from among vehicles that are included in the plurality of vehicles and that aim at a destination identical to the destination of the first vehicle, and
transmit, to the first vehicle, information about each of the candidate vehicles selected.
2. The server according to claim 1 , wherein
the first vehicle is configured to, when a user selects from among the candidate vehicles a second vehicle with which the inter-vehicle charging is desired, transmit, to the server, information for specifying the second vehicle selected, and
the server is configured to make pairing between the first vehicle and the second vehicle.
3. The server according to claim 2 , wherein
the server is configured to, when pairing between the first vehicle and the second vehicle completes, transmit reservation request information for securing a charging execution location for the inter-vehicle charging to the charging station, and
the charging station is configured to secure the charging execution location in accordance with the reservation request information.
4. The server according to claim 2 , wherein
the server is configured to
when pairing between the first vehicle and the second vehicle completes, determine a charging execution location for the inter-vehicle charging based on location information about each of the first vehicle and the second vehicle, and
transmit location information about the charging execution location to the first vehicle and the second vehicle.
5. The server according to claim 1 , wherein the information about each of the candidate vehicles includes at least one of a power-suppliable amount, an available time, and an electric-power unit price about each of the candidate vehicles.
6. An information providing system comprising:
a plurality of vehicles each equipped with a power storage device;
a charging station configured to supply electric power; and
a server configured to communicate with the plurality of vehicles and the charging station,
each of the plurality of vehicles being configured to
allow charging of the power storage device using electric power from the charging station, and
perform inter-vehicle charging for charging another vehicle using electric power of the power storage device,
the server being configured to
obtain a congestion degree in the charging station based on information from the charging station,
obtain a destination of each of the plurality of vehicles,
when the charging station is installed as an annex at a destination of a first vehicle included in the plurality of vehicles, and when the congestion degree in the charging station exceeds a threshold value, select at least one of candidate vehicles each permitting the inter-vehicle charging from among vehicles that are included in the plurality of vehicles and that aim at a destination identical to the destination of the first vehicle, and
transmit, to the first vehicle, information about each of the candidate vehicles selected,
the first vehicle being configured to display, to a user, information about each of the candidate vehicles from the server.
7. A method of providing information to a vehicle equipped with a power storage device,
the vehicle being configured to communicate with
a charging station configured to supply electric power and
a server,
the vehicle being configured to
allow charging of the power storage device using electric power from the charging station, and
perform inter-vehicle charging for charging another vehicle using electric power of the power storage device,
the method comprising:
obtaining, by the server, a congestion degree in the charging station based on information from the charging station;
obtaining, by the server, a destination of the vehicle;
when the charging station is installed as an annex at the destination of the vehicle, and when the congestion degree in the charging station exceeds a threshold value, selecting, by the server, a candidate vehicle permitting the inter-vehicle charging from among other vehicles that aim at a destination identical to the destination of the vehicle;
transmitting, from the server to the vehicle, information about the candidate vehicle selected; and
displaying, in the vehicle, information about the candidate vehicle.
