发明名称 Power supply unit, distributed power supply system and electric vehicle loaded therewith
摘要 A power supply unit with improved charge/discharge operation for use in distributed power supply system or electric vehicles. The power supply unit includes a storage battery comprising a plurality of circuits connected in series. Each of the plurality of circuits includes a first cell group and a second cell group connected in parallel. The first cell group includes lithium secondary cells or electrical double layer capacitors. The second cell group utilizes an electrolyzable electrolytic solution, or is capable of generating recombinable gas. The second cell group may include lead cells, nickel hydrogen cells, nickel cadmium cells and/or fuel cells. A charger/discharger is provided for controlling charge/discharge of the storage battery adapted to charge the storage battery up to a voltage at which the electrolytic solution of the second cell group is electrolyzed, or to a voltage at which the generated gas is recombined.
