Abstract: A method of manufacturing a bipolar battery stack (10) provides a first bipolar electrode (12) with an electrically conductive carrier foil (121) and a central region (124) coated on both sides with electrode material. A carrier foil edge (125) completely surrounds the central region (124) and is free of electrode material. A first sealing bead (201) is on the carrier foil edge region (125) to surround the carrier foil central region (124). An electrically insulating, ion-permeable, planar separator (18) is placed on the first sealing bead (201) laterally beyond the carrier foil central region (124). A second sealing bead (202) is applied to the edge region of the separator (18) beyond the carrier foil central region (124) to form a ring encircling the carrier foil central region (124), and another one is placed on the second sealing bead (202). The method repeats these steps a predetermined number of times.

Abstract: In the electrical energy storage element in accordance with the invention, a plurality of electrochemical cells that are each formed with a cathode and an anode as electrodes and an electrolyte are arranged stacked above one another. They are enclosed at one side by a top plate formed from an electrically conductive material, in particular aluminum, and at the oppositely disposed side by a base plate formed from an electrically conductive material, in particular aluminum. The base plate is coated by a cathode or by an anode and the cover plate is coated in a complementary manner by an anode or by a cathode. The anodes and cathodes are each formed at oppositely disposed surfaces of an electrically conductive carrier film which preferably comprises aluminum, copper, steel or an electrically conductive plastic.

Abstract: A method determines and/or predicts a maximum power capacity of a battery by using a model of the battery based on an electric equivalent circuit diagram that predicts the maximum power capacity of the battery. The maximum power of the battery is prognosticated for a defined prognosis period and for the different operating modes with respect to the charging or discharging operation, considering the maximum allowable operating voltage and the maximum allowable operating current.

Abstract: A method is provided for determining and/or predicting the high current carrying capacity of a battery, wherein the parameters of a model of the battery impedance are used as a basis, and from which the high current carrying capacity of the battery is determined. Different parameters are used as the basis for the charging and discharging processes.
