Abstract
A charge control device for providing a constant charge voltage with temperature compensation to a battery being charged by a constant current charger is provided. The device includes a first electrical connector that couples to a positive terminal of the battery and a second electrical connector that couples to a negative terminal of the battery. A current bypass circuit electrically couples to the positive and negative terminals of the battery through respective first and second electrical connectors. The current bypass circuit includes a bypass path for a portion of a charge current from the constant current charger to flow, thereby maintaining a substantially constant voltage across the battery terminals at a particular temperature.
