ABSTRACT:
An interface circuit device for safe and efficient charging and/or discharging of any multicelled battery or pack of batteries. The device includes circuitry for protection of said battery or pack of batteries from overcharge, overdischarge and overheating during charge or discharge. The cells of the multicelled battery or individual batteries of the battery pack are charged individually in parallel and discharged together in series through said device, while being individually sensed and individually disconnected by a protective circuitry. The device is preferably part of the product powered by the battery, not part of the battery.
