Abstract
A charge current control system is disclosed. One embodiment of the present invention includes a voltage detecting component that determines whether voltage stored by a load is at a voltage threshold. Also included are current supplying components that supply a charge current to the load that attains a plurality of magnitudes. The supply of the charge current is facilitated by a single charge current pass component over the course of a charge cycle. The magnitude of the charge current is based on the outcome of a determination of whether the minimum voltage threshold is reached.
