A motor vehicle with electric drive device and a rechargeable electrochemical energy storage

The invention relates to a motor vehicle with a system voltage, in particular a high-voltage system voltage, having at least one electric drive device, and a rechargeable electrochemical energy storage. The energy store comprises in turn a plurality of modules which each include an electrode stack at least comprising at least two unit cells. In each unit cell, an anode material having an anode layer, an electrolyte having the electrolyte layer and a cathode material containing cathode layer stacked sequentially, wherein in each case an electrically conductive and insulating for the charge-transporting ion bonding layer is disposed between two adjacent unit cells, the cathode layer of a first outermost unit cell of at least one electrode stack to the positive terminal and the anode layer of a second outermost unit cell of an electrode stack to the negative pole of the respective module is at least electrically connected to two adjacent unit cells in the at least one electrode stack are arranged in such a way that the anode layer of one unit cell with the cathode layer of the other unit cell is electrically connected, wherein all the modules are electrically interconnected in parallel and in a have substantially the same effective electric power, and wherein the total capacity of the electrochemical energy storage device is divided between the modules so that a module, each having a partial capacity, in particular from 20 100 to 0.02 100, and each module of the plurality of modules each the system voltage provides.
