Abstract: A wasteful consumption of electric energy supplied to charge a battery is reduced when the battery is charged with a low charging efficiency due to a high battery temperature. The battery, typically comprising nickel-hydrogen secondary cells, is prevented from being deteriorated due to a high battery temperature after the battery is charged. While the battery is being charged, the battery is cooled by a battery cooling unit to prevent the charging efficiency from being lowered. If the battery temperature rises above a predetermined temperature, a contactor is opened to temporarily stop the charging of the battery, and the battery is cooled by the battery cooling unit. After the battery is charged, the battery is cooled if the battery temperature is high.
