An electric power storage system for a vehicle includes a temperature sensor configured to detect a temperature of a battery, a battery heater, a charger connectable with an external power supply and configured to deliver external power to the battery and the battery heater, and a controller. In the system, a first electric power is supplied to the battery heater when the state of charge of the battery is larger than a predetermined value and the temperature of the battery is equal to or lower than the predetermined temperature, and a second electric power is supplied to the battery heater when the state of charge of the battery is equal to or smaller than the predetermined value and the temperature of the battery is equal to or lower than the predetermined temperature. The first electric power is smaller than the second electric power.
