PROBLEM TO BE SOLVED: To provide heater operation control for making the temperature of a battery reach a predetermined temperature at a finish time of charging of a timer.SOLUTION: When a finish time (TIME_e) of external charging is set, a residual time (t_r) from a present time (TIME_c) at the setting time till the finish time is calculated (S305). A temperature increasing time (t_h) required to increase the temperature of a power storage device to a target temperature by driving a heater is specified by using a predetermined corresponding relationship (S306). The predetermined corresponding relationship is the corresponding relationship of the residual time, the temperature of the power storage device at the present time, environmental temperature (Tout) and the temperature increasing time. On the basis of the finish time and the temperature increasing time, the operation of the heater is started so that the temperature of the power storage device at the finish time reaches the target temperature (S309). The heater is operated during only the temperature increasing time, so that the temperature of the power storage device is made to reach the target temperature at the finish time by the operation of the heater.SELECTED DRAWING: Figure 4 |
