PROBLEM TO BE SOLVED: To provide a charging circuit, wherein the variations in voltage, from cell to cell, is suppressed in the process of charging multiple power storage cells. SOLUTION: The charging circuit includes multiple power storage cells connected in series, an alternating-current power supply that charges the power storage cells, as many double series diodes as the power storage cells which are respectively connected in parallel with the power storage cells, and as many capacitors as the power storage cells which are connected between the midpoint between two diodes comprising each double series diode and the alternating-current power supply. During charging, the voltage of each power storage cell is charged uniformly, by alternating-current power supplied from the alternating-current power supply. COPYRIGHT: (C)2011,JPO&INPIT
