Method for compensating for measuring error in detecting current in an energy storing means

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...

More Information
Summary: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), (10) 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 measured values (30).
