ABSTRACT:
A switched capacitor system for automatic battery equalization can be used with series coupled batteries as well as primary and backup batteries which are alternately couplable to a load. The system includes a plurality of capacitors and a plurality of switching elements. Each of the capacitors is switched back and forth between a predetermined pair of batteries for the purpose of transferring charge therebetween and equalizing the output voltages of each of the batteries in the pair. The capacitors and switching elements can be configured in a modular fashion. Multiple modules can be used, for example, in combination with multiple batteries which are series coupled to one another. The system could be used in electric vehicles and in battery back-up systems of all types.
