ABSTRACT:
A battery charging apparatus that charges a plurality of batteries to equal voltage levels. The apparatus has a transformer that acts as a flyback circuit to charge the plurality of batteries. The transformer has a primary winding and a plurality of secondary winding circuits, each secondary winding circuit having a secondary winding and a diode. A different secondary winding circuit is coupled across each battery. The diodes cause only the battery having the lowest voltage among the plurality of batteries to receive energy on a transformer pulse. This occurs until that battery is charged to the level of the next lowest voltage battery, at which time both batteries will receive energy during the pulse. The sequence is followed until all the batteries are charged equally and to a predetermined threshold level.
