Abstract: Defining magnetic locks with permanent magnet and inductive coil that can be controlled instantaneously on demand within a battery pack by injection of a low electrical current from one or more BMSs. Whatever the positioning of the magnetic locks within the battery pack, one or more controlling BMSs can be positioned either on each accumulator or busbar, or on a branch to control on demand the set of accumulators in electrical series or in parallel, in the branch, either singly or at overall pack level.

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.
