20130130086 | ELECTRICAL ENERGY STORAGE DEVICE WITH FLAT STORAGE CELLS - In an electrical energy storage device with a plurality of flat storage cells for storing and delivering electrical energy having flat current conductors arranged at the narrow sides of the storage cells, and with a retaining apparatus for fastening the storage cells, at least one storage cell is fastened by the retaining apparatus at at least two, particularly opposite, narrow sides. In this arrangement the retaining apparatus exerts a tensile force on the storage cell that acts in the extension plane of the storage cell, by which the storage cell is tensioned. The retaining apparatus may also be equipped with a cooling device for cooling the storage cells, wherein the storage cells may particularly be cooled via their current conductors. | 05-23-2013 |
20130141049 | BATTERY AND METHOD FOR OPERATING A BATTERY - The method for operating a battery including several electrochemical cells and a battery control unit, includes collecting operating parameter data of the battery, transmitting the operating parameter data to the battery control unit, and determining whether a predefined relationship of the collected operating parameter data with regard to predefined operating parameter values exists for the battery, and carrying out normal operation of the battery if it does. If, it has been determined that the predefined relationship with respect to the predefined operating parameter values does not exist, a query is transmitted to a decision unit as to whether an exception operation of the battery is to be carried out, and a response to the query by the decision unit is determined. The response is then transmitted to the battery control unit, and an exception operation of the battery is performed by the battery control unit depending on the response. | 06-06-2013 |
