Problems solved by technology
If the energy storage battery is used, for example, in a battery system with an integrated converter, a so-called BDI, the inductive component of the energy storage battery impedance can lead to this inversion at a high operating frequency of the converter. Correspondingly high energy losses in the power electronic switching devices of the
This can therefore lead to increased wear of the switchgear, lower efficiency of the BDI, and increased manufacturing outlay for implementing a cooling system with sufficient cooling capacity

Description
technical field [0001] The invention relates to an electrical energy storage battery and a method for producing an electrical energy storage battery. Background technique [0002] The DC power is usually taken from or fed into the electrical energy storage battery. Therefore, currently known configurations of energy storage batteries are optimized for the specific energy or power density and ohmic internal resistance of the energy storage battery. [0003] In many applications of electrical energy storage batteries, the storage cells are interconnected into battery modules in a series or parallel arrangement in order to adjust desired output parameters such as overall voltage, voltage range, stored energy or power density. Document DE 10 2010 035 114 A1 discloses, for example, a battery unit having a plurality of battery cells each having battery cells galvanically coupled via bus bars. Document EP 2 413 414 A2 discloses a flat battery (Akkuflachzelle) with anode and catho...
