Abstract:
1. A charging device for charging a battery mounted on a vehicle by an external power supply, said vehicle configured to increase limitation on electric power charged to and discharged from said battery according to increase in temperature of said battery when said battery temperature exceeds a predetermined temperature, said charging device comprising: a temperature sensor for detecting the temperature of said battery, a charger receiving electric power from said external power supply to charge said battery, and a control device controlling said charger such that said battery is charged at a charging rate determined based on a temperature difference between said predetermined temperature and said battery temperature, said vehicle on which said battery is mounted being capable of repeatedly executing a charging operation towards said battery from outside the vehicle and a vehicle-running operation, said control device determining said charging rate based on a temperature increase expected amount when said vehicle runs next time and said temperature difference.
