Power supply unit, distributed power supply system and electric vehicle loaded therewith
First Claim
1. A power supply unit capable of being charged and discharged, comprising:
- at least a first cell; and
a plurality of second cells connected in parallel to said first cell, and capable of selected one of the electrolysis of the electrolytic solution and the recombination of the generated gas;
wherein a plurality of said parallel circuits each including the first cell and the second cells are connected in series, and wherein a charger/discharger is adapted to charge said cells up to a voltage at which the electrolytic solution of said second cells is electrolyzed or a voltage at which the generated gas is recombined.

Abstract
A power supply unit, a distributed power supply system and an electric vehicle loaded therewith, capable of charge/discharge operation are disclosed. A first cell group is connected in parallel to a second cell group in which the electrolytic solution can be electrolyzed or the generated gas can be recombined. A plurality of the parallel circuit pairs are connected in series, and the series circuit is connected with a charger/discharger to constitute the power supply unit. The charger/discharger charges the power supply unit up to a voltage at which the electrolytic solution of the second cell group is electrolyzed or the generated gas is recombined.

9. A distributed power supply system,
wherein a first power supply unit including a first cell group and a second cell group is connected in parallel with a second power supply unit, wherein in the case where said second power supply unit is deficient of power, power is supplied as an assistance from said first power supply unit; wherein in the case where extraneous power is generated by said second power supply unit, said first power supply unit is charged by a charger with the power of said second power supply unit to a voltage at which the electrolytic solution of said second cell group of said first power supply unit is electrolyzed or the generated gas is recombined.
