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).
