IPC: H02J7/00
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To realize a quick charging without overcharging by determining the temperature rise rate per unit time when charging a secondary battery and by stopping the charging when the temperature rise rate begins to increase after decreasing from the initial value. SOLUTION: The temperature of a secondary battery 21 is detected by a temperature sensor 22, for example as a change in resistance value of a thermistor, and moreover this change in the resistance value is converted into a battery temperature information by a temperature detection circuit 17 and then input to a control circuit 16. The control circuit 16 turns a switch element 15 on and quick charging is started. As this quick charging begins, the control circuit 16 calculates the temperature rise rate per unit hour of the second battery 21 and monitors whether the temperature rise rate has decreased or not. If the temperature rise rate decreases, the control circuit 16 calculates the temperature rise rate in succession, and then monitors whether the temperature rise rate has increased or not. When the temperature rise rate rises, the control circuit 16 turns the switch element 15 off state and stops the quick charging.
