NOVELTY - The battery pack has a bottom-side holding device (5) which is arranged at bottom side (3) of housing (1), and cover-side holding device is arranged on one side of cover (2) of the housing. A device for electrical contact with positive terminal is electrically contacted with positive terminal of battery cell, and the device for electrical contact with negative terminal is contacted with negative terminal of battery cell. The device for electrical contact with positive terminal or the device for electrical contact with negative pole is integrated in the bottom side of housing.    USE - Battery pack mounted in motor vehicle e.g. electric vehicle and hybrid vehicle.    ADVANTAGE - The integration of the device for making electrical contact is obtained so that improved protection against accidental contact of the device for electrical contact can be achieved after the assembly of housing with battery cells. The mechanically rigid attachment is provided so that good electrical contact and good thermal contact with the battery cell can be achieved. The spring element is provided in a simple and releasable mechanical fixing, for fixing and holding battery cell, such that defective battery cells can be replaced without having to disconnect the remaining battery cells from the holder. The spring elements allow simple and secure mechanical attachment of the battery cells during wire bonding process. The improved electrical contactability of the receiving device arranged in the battery cell can be attained by the maximum opening. The battery pack is simple to manufacture for axial fixation of battery cell, so that slipping of battery cell in relation to the bottom and top side of clamped condition of battery cell is prevented.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for arrangement for mounting battery cells.    DESCRIPTION OF DRAWING(S) - The drawings show the perspective views of the housing.
