Abstract:
A battery pack wherein each battery is mechanically and electrically connected by a magnetic device to a busbar. In case of failure of any accumulator, it is disconnected completely passively because its failure generates an inactivation of the magnetic device. The disconnection causes the gravity drop of the accumulator and the possibly completely passive implementation of an accumulator shunt.
