Charging controller

Provided is a charging controller that controls a process of charging a battery from an external power source. When an outside air temperature is equal to or lower than a predetermined temperature, the charging controller charges the battery from a time earlier than a scheduled time of use of the battery by a predetermined time until the scheduled time of use. Thus, even when the outside air temperature is equal to or lower than the predetermined temperature, the temperature of the battery has been raised by heat generated during the charging by the time of use of the battery.
