UNIT OF STORAGE BATTERIES, CONTAINING STACKS OF ASSEMBLIES MADE ON THE BASIS OF BOARDS AND ACCUMULATOR BATTERIES Russian patent published in 2019 - IPC H01M2/10 H01M10/44 H02J7/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to a battery pack comprising a stack of assemblies made from boards and accumulator batteries. Each assembly made on the basis of boards and accumulator batteries includes a circuit board, an electric connector installed on the circuit board, and an element of the accumulator battery attached to the side of the circuit board. Battery cell elements are arranged between circuit boards to form a layered structure, and the connectors are connected to each other. Circuit boards and connectors electrically connect elements of accumulator battery to each other, at that, stack of batteries is equipped with control board, which is configured to measure voltage on each cell of battery through communication line, as well as identification of any faulty battery cells. Besides, each assembly includes a heating element and switches. Technical result of invention is increase of service life of accumulator batteries due to prevention of deterioration of characteristics of accumulator batteries.

EFFECT: device is easy to maintain due to absence of need for soldering of terminals of faulty element of storage battery and repeated soldering.
