Abstract
An execution device of a controller for a vehicle is configured to, when the heater is driven, execute predicting a temperature of a battery that is to occur at a preset time when the heater has been stopped at a determination time that is earlier than the preset time, calculating, based on the predicted temperature of the battery at the preset time, a maximum discharge amount of the battery applicable at the preset time, and stopping a heater at the determination time on condition that the calculated maximum discharge amount at the preset time is greater than or equal to a predetermined lower-limit discharge amount at which a delayed response at start-up of the vehicle falls within an allowable range.
Claims4
A controller for a vehicle, wherein
- the vehicle includes a battery configured to store electrical energy for driving a drive motor and a heater configured to heat the battery,
- the battery is configured to be charged by a power supply facility such that a state of charge at a preset time reaches a predetermined target state of charge,
- the controller comprises an execution device, and
- the execution device is configured to, when the heater is driven, execute:
- predicting a temperature of the battery that is to occur at the preset time, in a case where the heater has been stopped at a determination time earlier than the preset time;
- calculating, based on the predicted temperature of the battery at the preset time, a maximum discharge amount of the battery applicable at the preset time;
- and
- stopping the heater at the determination time on condition that the calculated maximum discharge amount at the preset time is greater than or equal to a predetermined lower-limit discharge amount at which a delayed response at start-up of the vehicle falls within an allowable range.
