Abstract

A power storage system for a vehicle includes a battery, a temperature sensor, a battery heater, a charger, and a controller. The battery is configured to supply electric power to a motor for traveling of the vehicle, and configured to be charged with external power supplied from an external power supply. The temperature sensor is configured to detect a temperature of the battery. The battery heater is configured to raise the temperature of the battery. The charger is configured to be connectable with the external power supply, and deliver the external power to the battery and the battery heater, respectively. The controller is configured to perform charge control. The charge control is a control that charges the battery with the external power. The controller is configured to store a map. The map specifies, for each temperature of the battery, a ratio of a temperature-elevating power supplied to the battery heater to a maximum power of the external power at the time when a charging time is minimized. The controller is configured to calculate the ratio, using the map, from the temperature of the battery measured at the time when charging is started. The controller is configured to perform temperature regulation control during charging, using the temperature-elevating power corresponding to the calculated ratio. The temperature regulation control is a control that supplies a part of the external power to the battery heater during charging so as to raise the temperature of the battery.
