Abstract
The invention relates to a method for compensating for the measuring error in detecting current in an energy storing means (1), in which the detecting current is effected via a first current converter (9) and a second current converter (10) for higher currents, and the converter values (14), (15) of the two current converters (9), (19) are converted in an electronic evaluation unit (13) into measured values (17). The measured values for the battery current IBatt. (6) are measured with both current converters (9), (10) upon reaching a threshold (24), and from this the offset (27) of one current converter (10) is determined and corrected by the its measured values (30).

A method for compensating for measuring error in detecting current in an energy storing means (1), in which the detecting current is done via a first current converter (9) for low currents and via a second current converter (10) for higher currents, and the converter values (14), (15) are converted in an electronic evaluation unit (13) into measured values (17), characterized in that the measured values of the battery current (6) are measured with both current converters (9), (10) upon reaching a threshold (24), and from this measurement the offset (27) of one current converter (10) is determined and corrected by the its measured values (30).
