CHEMICAL CELL BATTERY WITH VOLTAGE BALANCE Russian patent published in 2009 - IPC H01M10/44 H02J7/00 

FIELD: electric engineering.

SUBSTANCE: invention relates to electric engineering. According to the invention, chemical cell battery (CCB) with voltage balance contains a multiple set of single CCBs or their modules connected as a serial electrical circuit, leveling unit for each two CCBs or modules of several CCBs ensuring voltage leveling for each two CCBs and modules of several CCBs. The output of the leveling unit connected parallel to CCB or CCB module. The battery also includes control unit for leveling unit. The leveling unit for each two CCBs or modules of several CCBs is represented as an equaliser to level voltage misbalance to CCB. The equaliser is made from choke connected to the point of serial connection of two CCBs or two CCB modules and to the poles of serially connected CCBs or two CCB modules via switches. Diodes are in parallel connection with the above-mentioned switches. The said diodes are open in current flowing direction from CCB minus side to plus side or from CCB module minus side to its plus side.

EFFECT: simplified circuit and improved weight and dimensions.
