A charge balancing system comprises a plurality of series connected batteries and a plurality of energy storage circuits. The system also includes switching circuitry for alternately connecting each energy storage circuit across a respective one of the batteries and in parallel with each other. The switching circuitry can also be controlled to couple a plurality of the energy storage circuits across a relatively-highly-charged battery and then across a relatively-weakly-charged battery.Field of SearchSERIALLY CONNECTED BATTERIES OR CELLSSwitchable to parallel connection With discharge of cells or batteries With individual charging of plural batteries or cells Having variable number of cells or batteries in series Bypassable battery cell PARALLEL CONNECTED BATTERIES BATTERY OR CELL DISCHARGING With charging BATTERY OR CELL CHARGING | |
