Abstract: A method for connecting cell outgoing conductors of a first and a second cell. Here, a connection between the first and second cell outgoing conductors is produced by means of a connecting apparatus, which includes a first and a second component. At the same time, however, the first and second components also have the function of pre-bending the cell outgoing conductor of the first and second cells, respectively, in order thus to enable a particularly low physical height of the cell outgoing conductor arrangement. A system according to the invention includes a first and a second cell, which have cell outgoing conductors that are connected and shaped in this way.

Abstract: The invention relates to a battery with battery cells and a method for monitoring and controlling the battery cells of the battery. The battery has a plurality of battery cell stacks which are connected in series. A battery cell stack may have an individual battery cell or may be constructed from battery cells which are connected in parallel. Sensors monitor the charge state of individual battery cells, individual battery cell stacks, individual pairs of battery cells and/or individual pairs of battery cell stacks. A charge compensation device has a target value table of the permissible charge state of individual battery cells. The charge compensation device varies the charge compensation depending on the charge state and, when the target value for the charge state of individual battery cells is reached, the charge compensation of the battery cells is interrupted.

Abstract: An electrochemical cell is provided. The cell includes a plurality of electrode sheets separated by at least one separator sheet. A positive extension tab is attached to a current collecting tabs of positive electrode sheets, and a negative extension tab is attached to current collecting tabs of the negative electrode sheets. The dimensions of the positive extension tab and the negative extension tab are selected such that temperature difference between positive extension tab and the negative extension tab are minimized when the electrochemical cell is in use.

Abstract: An energy storage cell having a flexible envelope, which cell is attached flat to a heat-conducting plate.

Abstract: An energy store (ESP1) for storing electrical energy, particularly for a motor vehicle, has the following characteristics. The energy store has at least one flat cell (Z1, Z2) having a flat cell body (ZK), which is bounded by two base surfaces (G11, G12, G21, G22), which extend parallel to a cell body plane, and by a first (ZB) and several second (ZD) side surfaces, which extend perpendicularly to the cell body plane (ZE) and connect the base surfaces. Furthermore, a cooling device having a cooling element (KF) is provided, wherein the cooling element is thermally coupled with the first side surface (ZB) in order to dissipate heat from the flat cell through the side surface. For improved heat removal, the cooling device also has a cooling plate (KB), which is thermally coupled with one of the base surfaces (G12, G21) of the at least one flat cell.
