Abstract

A storage battery arrangement includes a plurality of battery cells each having a cell housing having at least one cell terminal protruding from an end of the cell housing. The storage battery arrangement also includes a plurality of control units each having a control unit housing and electronic circuitry provided inside the control unit housing for monitoring and controlling at least one of the plurality of battery cells. The control units each include at least one control terminal extending to the outside of the control unit housing, the control terminal being electrically connected to the electronic circuitry. The size and shape of each of the control unit housings are substantially similar to the size and shape of the cell housings so that the control units can be arranged side-by-side among the battery cells and electrically connected the same way to the battery cells.
