摘要:
The invention relates to a battery with battery cells and a method for monitoring and controlling the battery cells of the battery. The battery has a plurality of battery cell stacks which are connected in series. A battery cell stack may have an individual battery cell or may be constructed from battery cells which are connected in parallel. Sensors monitor the charge state of individual battery cells, individual battery cell stacks, individual pairs of battery cells and/or individual pairs of battery cell stacks. A charge compensation device has a target value table of the permissible charge state of individual battery cells. The charge compensation device varies the charge compensation depending on the charge state and, when the target value for the charge state of individual battery cells is reached, the charge compensation of the battery cells is interrupted.

Disclosed is a method for controlling the operating point (AP, AP1, AP2) of a battery (1), such as a lithium ion battery, a nickel metal hydride battery or a lithium polymer battery. The charging state (SoC1, SoC2) of the battery (1) is recorded as a state variable which determines the current operating point (AP1, AP2) of the battery (1). The current operating point (AP1, AP2) is set by a corresponding set value (SoCAP1, SoCAP2) for the charging state (SoC1, SoC2) which is continuously adjusted depending on the temperature (T) and/or on the age state (SoH) of the battery.

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).
