Abstract
At a timing of time tbattery temperature Tbat lowers to Tbat_start and a warm-up request occurs, SOC at this time is a level, like time t, which allows a vehicle to travel by itself up to a battery charging facility and allows a battery charger to be connected to the battery charging facility. Since a warm-up permission judging value is set to SOCs_low that is substantially 0 at time t, in response to judgment of 'SOC≧SOCs_low (≈0)', warm-up of the battery is carried out from time tas shown by a solid line, then Tbat can be increased from time t. A battery charge time can be thus shortened. With this, in order that the battery does not freeze while the battery is unused, a control that warms up the battery by a battery-driven heater is performed while shortening the battery charge time.
