ABSTRACT:
A method for balancing charge of a plurality of series-connected batteries includes alternately coupling each of a plurality of energy storage circuits across a respective one of the batteries and in parallel with each other. 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.
