Abstract
According to the charge control method of the present invention, as an electric storage means, a group of capacitors is used that includen (where n is an integer of 2 or more) electric double layer capacitors, from first ton-th electric double layer capacitors, having an equal electrostatic capacity, and that is configured such that adjacent electric double layer capacitors are connected either in series or in parallel by a switch and then-th electric double layer capacitor and the first electric double layer capacitor are connected in parallel by a switch. Among then capacitors Ci constituting the electric storage unit, adjacent capacitors are sequentially switched from a series connection to a parallel connection, or then-th capacitor Cn and the first capacitor Care switched to a parallel connection state, whereby variations in the inter-terminal voltages of the capacitors are suppressed.
