Vehicle power supply control system, vehicle power supply control method, and storage medium
A vehicle power supply control system includes a communicator configured to receive an emergency notification for notifying that an emergency situation has occurred and a controller configured to control charging and discharging of a secondary battery that supplies electric power to an electric motor for outputting a travel driving force of a vehicle. The controller is configured to perform control for extending an electric power supply range in the secondary battery in a case where the communicator has received the emergency notification.
1. A vehicle power supply control system comprising:
a communicator configured to receive an emergency notification for notifying that an emergency situation has occurred; and
a controller configured to control charging and discharging of a secondary battery that supplies electric power to an electric motor for outputting a travel driving force of a vehicle,
wherein the controller is configured to perform control for extending an electric power supply range in the secondary battery in a case where the communicator has received the emergency notification, and
wherein the controller is configured to:
confirm whether or not a state of charge (SOC) of the secondary battery is greater than or equal to a predetermined value in a case where the communicator has received the emergency notification;
in a case where it is confirmed that the SOC is greater than or equal to the predetermined value, perform control for decreasing a lower limit value of a range in which the secondary battery can discharge the electric power; and
in a case where it is confirmed that the SOC is not greater than or equal to the predetermined value, perform control for increasing an upper limit value of a range in which the secondary battery can be charged, then, charge the secondary battery, and then, perform control for decreasing the lower limit value of the range in which the secondary battery can discharge the electric power.
2. The vehicle power supply control system according to claim 1 ,
wherein the controller is configured to:
confirm the SOC of the secondary battery in a case where the communicator has received the emergency notification; and
in a case where the state of charge is not a state of full charge, extend the electric power supply range in the secondary battery and operate an internal combustion engine of the vehicle to charge the secondary battery.
3. A vehicle power supply control method using a computer comprising:
performing communication for receiving an emergency notification for notifying that an emergency situation has occurred;
controlling charging and discharging of a secondary battery that supplies electric power to an electric motor for outputting a travel driving force of a vehicle; and
performing control for extending an electric power supply range in the secondary battery in a case where the emergency notification has been received,
wherein the performing of the control for extending the electric power supply range comprises:
confirming whether or not a state of charge (SOC) of the secondary battery is greater than or equal to a predetermined value in a case where the emergency notification has been received;
in a case where it is confirmed that the SOC is greater than or equal to the predetermined value, performing control for decreasing a lower limit value of a range in which the secondary battery can discharge the electric power; and
in a case where it is confirmed that the SOC is not greater than or equal to the predetermined value, performing control for increasing an upper limit value of a range in which the secondary battery can be charged, then, charging the secondary battery, and then, performing control for decreasing the lower limit value of the range in which the secondary battery can discharge the electric power.
4. A computer-readable non-transitory storage medium storing a program for causing a computer to:
perform communication for receiving an emergency notification for notifying that an emergency situation has occurred;
control charging and discharging of a secondary battery that supplies electric power to an electric motor for outputting a travel driving force of a vehicle; and
perform control for extending an electric power supply range in the secondary battery in a case where the emergency notification has been received,
wherein the performing of the control for extending the electric power supply range comprises:
confirming whether or not a state of charge (SOC) of the secondary battery is greater than or equal to a predetermined value in a case where the emergency notification has been received;
in a case where it is confirmed that the SOC is greater than or equal to the predetermined value, performing control for decreasing a lower limit value of a range in which the secondary battery can discharge the electric power; and
in a case where it is confirmed that the SOC is not greater than or equal to the predetermined value, performing control for increasing an upper limit value of a range in which the secondary battery can be charged, then, charging the secondary battery, and then, performing control for decreasing the lower limit value of the range in which the secondary battery can discharge the electric power.
