ABSTRACT:
A process for improving the charge state of a motor vehicle battery arrangement having at least one battery and a generator driven by an internal combustion engine. Output power of the generator being at least partially utilized in order to charge the battery arrangement in the vehicle. The generator has an output voltage, which varies due to fluctuations in the speed of rotation of the internal combustion engine, and which is controlled so that it does not exceed a specific threshold value. Immediately after a starting process, at least under specific operating conditions, a raising of the specific threshold value U.sub.limit occurs during a specific period.
