Abstract:
1. A power supply device mounted on a vehicle, comprising: a power storage unit capable of being charged; and a control unit controlling charging of said power storage unit, said control unit including a change instruction generation unit generating a change instruction instructing change of state of charge of said power storage unit, based on information representing possibility of use of said vehicle by a user, a target value setting unit setting, when charging of said power storage unit starts, a target value of state of charge of said power storage unit to a first value based on the condition of said power storage unit, and setting, when said change instruction is received after the start of charging of said power storage unit, said target value to a second value higher than said first value, and a charge processing unit executing a charging operation based on said target value, wherein information representing the condition of said power storage unit is information of temperature around said power storage unit; said control unit further includes an amount of change calculating unit calculating an amount of change in state of charge of said power storage unit necessary to increase temperature of said power storage unit; and said target value setting unit stores said second value in advance, and calculates said first value by subtracting said amount of change from said second value.
