Abstract: Battery assembly comprising a plurality of battery blocks, where each battery block comprises a first metal plate fixedly connected to the positive terminals of a plurality of rechargeable battery cell members and a second metal plate fixedly connected to the negative terminals of the cell members, further comprising a printed circuit board provided with an electronic circuit configured to monitor, control and/or balance said battery blocks, where the metal plates of subsequent battery blocks are fixedly connected to each other such that the battery blocks are electrically configured in series, and where the PCB is mechanically fixed to mounting flanges of the metal plates with mounting means that also provides an electric connection between the metal plates and the PCB. The advantage of the invention is that a self-supporting battery assembly that can be produced in a cost-effective way is provided.

Abstract: The invention concerns a battery assembly (1), comprising: at least a first block (4) of rechargeable battery cell members (3) that are arranged side by side in at least one row and that are electrically configured in parallel, wherein each cell member (3) has a first and a second electrode terminal (24, 25); a printed circuit board (PCB) (10) provided with an electronic circuit (11) configured to monitor, control and/or balance said first block (4) of cell members (3); and interconnecting means (6, 7, 8, 17, 18, 20, 28) arranged to connect the first electrode terminals (24) electrically to each other and to the PCB (10).
