Abstract: When an output voltage of a secondary battery cell E1 is obtained, only SW1 and SW2 are turned on. As a result, a capacitor C1 is charged by a secondary battery cell E1. With a delay of a time period ÄT, SW1 and SW2 are turned off. SW4 and SW5 are turned on. As a result, electric charges of the capacitor C1 are moved to a capacitor C2. Those operations are repeated until the potential of the capacitor C2 becomes almost equal to the output voltage of the secondary battery cell E1. When the potential of the capacitor C2 becomes almost equal to the output voltage of the capacitor C2, the potential of the capacitor C2 is detected by the voltage detector 11. A first terminal of the capacitor C2 is connected to a ground potential. As a result, the voltage of the secondary battery cell E1 can be stably detected. When the secondary battery cell E2 is detected, only SW5 is turned on. As a result, the capacitor C2 is charged by the secondary battery cell E2.
