Abstract
Apparatus and methods for quickly and safely recharging and magnetically balancing a series of batteries or battery groups to their full charge capacity. The battery charging system includes a multi-output transformer having an impedance in the primary, a secondary with multiple outputs, and circuitry for charging each of the batteries or battery groups whereby the portion of charging current flowing from each of the multiple outputs to each of the batteries or battery groups relates inversely to the voltage of each of the batteries or battery groups.
