Abstract
An energy storage system supplies electric energy to consuming devices in a vehicle, particularly in a motor vehicle. The system includes a first power grid having a first energy accumulator and a second power grid having a second energy accumulator, the first and second power grids being electrically coupled such that electric energy from the first power grid is feedable to the second power grid for regenerating the second energy accumulator. The energy storage system is operatively configured such that it is detected when a number of conditions has been met, the number of conditions including at least that an external charging device is connected to the first power grid for charging the first energy accumulator. In the event that the number of conditions has been met, regeneration of the second energy accumulator is carried out.
