Abstract
A charging device for charging a battery () by an external power supply () includes a temperature sensor () for detecting the temperature of the battery, a charger () receiving electric power from the external power supply to charge the battery, and a control device () controlling the charger such that the battery is charged at a charging rate determined based on the temperature difference between a charging/discharging limitation start temperature and the battery temperature. Preferably, the control device () determines the charging rate based on the difference between the amount of charge corresponding to full charge of the battery () and the current remaining amount of charge, and the temperature difference. Preferably, the vehicle () on which the battery () is mounted repeatedly carries out charging and vehicle-running. The control device () determines the charging rate according to the temperature increase expected amount when the vehicle runs next time.
