ABSTRACT:
Battery pack which includes rechargeable battery cells in conjunction with a charge protection circuit to prevent damage to the battery pack. The battery pack further includes a component in which predetermined battery parameters definitive of a battery pack characteristic may be stored, together with a battery parameter sensor, and a micro-controller responsive to the sensing of a battery parameter for controlling the battery pack characteristic based upon the sensed parameter. In one aspect, the sensed parameter may be the onset of substantially full charge as provided by a current source operably connected to the battery pack and subject to being disconnected when a predetermined cell temperature is reached which is indicative of full charge.
