1. A motor vehicle comprising:
- a storage battery connecting in series at least two parallel circuits, each of the at least two parallel circuits including a first cell group and a second cell group connected in parallel, said second cell group being capable of electrolysis of the electrolytic solution thereof or recombination of the generated gas thereof;
a power supply unit including a charger/discharger for controlling charge/discharge of said storage battery and adapted to charge said storage battery up to a voltage at which the electrolytic solution of said second cell group is electrolyzed or a voltage at which the generated gas is recombined; and
a motor-generator for driving a motor by electric power supplied by said power supply unit when said motor vehicle is in power running, and for generating electric power when said motor vehicle is in regeneration;
wherein when said motor vehicle is in regeneration, said storage battery is charged by the electric power of said motor-generator up to a voltage at which the electrolytic solution of said second cell group 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.
