Abstract
When warming-up of a battery is in progress (S), a battery charge state at the warming-up start time of the battery is set to a battery hold capacity SOC(S, S), and a charge power for the battery is controlled so that a battery charge state SOC is kept at SOC. When a present time is in a timer charge reservation time (S), the charge power for the battery is controlled so that SOC becomes a full charge state SOC(S). Even if SOC has a tendency to temporarily decrease due to a rapid increase of heater consumption power just after start of warming-up of the battery, by keeping SOC at SOC(SOC=SOC), SOC can reach a full charge state as intended during the timer charge reservation time. A proportion of charge using low-priced midnight power is increased to a maximum then running cost can be suppressed.
