초록

This invention includes a trickle charging circuit that works with a series charging element to charge battery cells with a low, constant current when the voltage of the cell is below a predetermined operational range. The trickle charging circuit includes a control transistor that is actuated by a current source when both the power supply and undervoltage battery cell are coupled. The trickle charging continues until a minimum operational voltage of the cell is reached. The invention includes a means for rapid charging the cell once the cell voltage is ...
