Abstract
The invention relates to a method for compensating for the measuring error in detecting current in an energy storing means ( ), in which the detecting current is effected via a first current converter ( ) and a second current converter ( ) for higher currents, and the converter values ( ), ( ) of the two current converters ( ), ( ) are converted in an electronic evaluation unit ( ) into measured values ( ). The measured values for the battery current I ( ) are measured with both current converters ( ), ( ) upon reaching a threshold ( ), and from this the offset ( ) of one current converter ( ) is determined and corrected by the measured values ( ).
