The invention relates to a vehicle electrical system that includes a first energy accumulator which has a first maximum open circuit voltage when the first energy accumulator is fully charged, and a second energy accumulator which has a second maximum open-circuit voltage when the second energy accumulator is fully charged. The second maximum open circuit voltage is higher than the first maximum open circuit voltage. The vehicle electrical system also includes a generator configured to generate electrical energy for the vehicle electrical system and a control unit that is configured to detect a recuperation mode of the vehicle. The control unit is also configured to cause the generator, while the vehicle is in the recuperation mode, to generate electrical energy with a charge voltage which is in or above a buffer voltage range, wherein the buffer voltage range lies between the first maximum open circuit voltage and the second maximum open circuit voltage.
