A battery pack comprising a power cell for providing power to a load or for receiving a charge from a charger, a first protection circuit for protecting from overvoltage and/or overcurrent conditions, and a second protection circuit for protecting from overtemperature conditions. The protection circuits independently control one or more electronic switching devices, through which passes substantially all of the current supplied by the power cell. When overvoltage and/or overcurrent conditions exist, the first protection circuit causes at least one of the switching devices to move to a non-conducting condition. Similarly, when an overtemperature condition exists, the second protection circuit causes at least one of the switching devices to move to a non- conducting condition.
Bloc-batterie comprenant un élément de pile pour envoyer du courant à un consommateur ou pour recevoir la tension provenant d'un chargeur, un premier circuit de protection contre la surtension et/ou une surintensité du courant, et un second circuit de protection contre les températures excessives. Les circuits de protection contrôlent de manière indépendante un ou plusieurs dispositifs d'interruption que traverse le courant provenant de l'élément de pile. Lorsqu'une surtension ou qu'une surintensité de courant se produit, le premier circuit de protection déplace un des dispositifs d'interruption vers une position d'ouverture de circuit. De même, lorsqu'une surchauffe se produit, le second circuit de protection déplace au moins un des dispositifs d'interruption à une position d'ouverture de circuit.
