Rechargeable battery e.g. nickel-metal hydride battery, for use as electro-chemical energy storage in e.g. electric vehicle, has line elements comprising specific distance to each other in region, where distance is lesser than region

摘要

The battery (2) has multiple battery cells (5.1-5.10) that are arranged in a serial connection. Each battery cell has a plus contact element (6) and a minus contact element (7) that electrically contact with one another by line elements (13-15) e.g. line bars. The line elements form six line elements (16.1-16.5) that have current directions aligned opposite to each other in a region (B) during operation of battery. The line elements (13, 14) have specific distance to each other in the region, where the distance is lesser than the region.
