Abstract
The invention is directed to a rechargeable battery pack for an electrical load with the load being connected to the rechargeable battery pack by a connection cable. A housing of the rechargeable battery pack has an inner space for accommodating a large number of rechargeable individual cells which are electrically connected to one another and supply the load via the connection cable. To provide the housing with a high level of stability, provision is made for the receiving space in the housing to be subdivided into individual receptacles by partition walls. A cell pack includes a predefined number of the individual cells and is arranged in a corresponding individual receptacle. Each cell pack forms an independent unit which is held in the individual receptacle. The individual cells of a cell pack are electrically and mechanically connected to one another by cell connectors.
