    • When warming-up of a battery is in progress (S12), a battery charge state at the warming-up start time of the battery is set to a battery hold capacity SOC hold (S14, S15), and a charge power for the battery is controlled so that a battery charge state SOC is kept at SOC hold . When a present time is in a timer charge reservation time (S11), the charge power for the battery is controlled so that SOC becomes a full charge state SOC full (S17). 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 hold (SOC = SOC hold ) 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.
    • 当电池预热正在进行时(S12),将电池的预热开始时间的电池充电状态设定为电池保持容量SOChold(S14,S15),并且电池的充电电力为 控制为使电池充电状态SOC保持在SOChold。 当当前时间处于定时器充电保留时间(S11)时,控制电池的充电功率以使SOC变为满充电状态SOCfull(S17)。 即使由于在电池预热开始之后加热器消耗功率的快速增加而使SOC暂时下降,通过将SOC保持在SOChold(SOC = SOChold)SOC可以达到预期期间的预期的完全充电状态 定时充电预约时间。 使用低价午夜电力的费用比例增加到最大,可以抑制运行成本。
