Abstract: A device for determining cell voltages across series-connected battery cells of a cell stack is provided. The battery cells are combined to form packs having a plurality of series-connected battery cells. Each pack has an associated voltage measuring device for determining the cell voltages of the individual battery cells of the respective corresponding pack. The device has a voltage follower for at least two adjacent packs, which is connected to the current path between the two adjacent packs and receives a potential of the one pack as input signal, and also a reference voltage, and provides a supply voltage for the voltage measuring device of the other pack at low impedance as output signal.

Abstract: A filter arrangement for filtering parasitic induction currents may include an electrically conductive housing part that at least partly surrounds a cavity, an electric ground connection on the housing part for establishing an electric connection to an electric ground, a busbar in the cavity, and at least one electric filter component electrically connected between the busbar and the housing part and mechanically secured to the housing part and to the busbar. A voltage converter may include at least one such filter arrangement.

Abstract: A charge redistribution circuit (2) for an energy storage unit (1) with several storage elements (4) which are connected in series comprises several charge redistribution control units (5) for monitoring and redistributing the load, each of which is assigned an energy storage sub-group (3) of storage elements (4). The charge redistribution control units (5) take the energy used for their own supply in each case from the sub-group (3) assigned to them, and are thus supplied with a voltage which is higher than the voltage of the individual storage element (4) and lower than the voltage of the energy storage unit (1). The charge redistribution circuit (2) is established in such a manner that a monitoring and—when necessary a charge redistribution is achieved for each individual storage element (4).
