Device and method for balancing the state of charge of battery cells and battery module, battery, battery system, vehicle, computer program and computer program product

摘要

The invention relates to a device for balancing battery cells, characterized by: means for determining measured values for a voltage or a state of charge of each of the battery cells; a device for calculating a compensation requirement for each of the battery cells from the determined measured value for the battery cell and a lowest determined measured value from all battery cells; and means for discharging the battery cells based on the respective calculated compensation demand so that the balancing of the battery cells can be distributed over a common time period, a battery module, a battery, a battery system, a vehicle, a method, a computer program and a computer program product.
