Abstract
An enhanced battery pack having an enhanced protection system addresses a potential weakness of the conventional protection system of a conventional battery pack. The enhanced protection system includes both the convention protection circuit and a redundant protection circuit. The redundant protection circuit is either a duplicate copy of the conventional protection circuit or is at least a functional equivalent of the conventional protection circuit. The components of the redundant protection circuit are electrically coupled into the enhanced battery pack in a parallel fashion with the corresponding components of the conventional protection circuit. Consequently, if one or more components of the conventional protection circuit fail due to defective conditions of the one or more components of the conventional protection circuit, the redundant protection circuit will still be operable to allow the enhanced battery pack to function while the enhanced protection system continues to protect the enhanced battery pack.
