DEVICE FOR ELECTRICALLY INTERCONNECTING CELLS IN A BATTERY PACK BY MEANS OF CELL CONNECTORS AND BATTERY PACK WITH SUCH CELL CONNECTORS

The device for electrically interconnecting cells (12) in a battery pack (11), comprises cell connectors (15), which are electrically insulated from one another on a mounting plate (16) and are arranged for connecting two cell poles. Each cell connector comprises a flexible bracket extending itself by a connection-area. The flexible brackets are coupled with a spring-elastic structure with the connection-area in meander-shaped manner and are distanced with its apex regions from the mounting plate. Each cell connector is held in connection-area between two brackets on the mounting plate.

Each cell connector comprises a flexible bracket extending itself by a connection-area. The flexible brackets are coupled with a spring-elastic structure with the connection-area in meander-shaped manner and are distanced with its apex regions from the mounting plate. Each cell connector is held in connection-area between two brackets on the mounting plate. The bracket turned away from its respective connection-area is held in the bracket-end on the mounting plate. The cell connectors are mounted by rivet-like hot-fittings on the mounting plate. The bracket-ends run-out from the mounting plate, where each bracket comprises a hole (25) in a contacting area formed for connecting with a cell pole. The hole is formed in vertical region of the bracket. The mounting plate comprises a through-hole in the contacting region in which the holes are arranged in mounting condition of the cell connector. The contour of the holes passes a cell pole over a lateral surface mounting on the bracket. The holes of the cell connector comprise a connection piece, whose materials are selected in such a way that the connector pieces are connected together with materials of the lateral surface of the cell pole in a hot-joining process such as welding or soldering, or cold joining process in power- and/or material fit manner. The mounting plate is mounted with a stamping grid made of copper, copper alloy, aluminum or aluminum alloy, from double-frame and a single-piece conductor web, which has an end formed as connecting pin. The cell connector is made of copper, copper alloy, aluminum or aluminum alloy. The contacting areas are made from copper, copper alloy, aluminum, aluminum alloy, steel, nickel or nickel alloy. An independent claim is included for a battery pack.
