Abstract

A system for a drive energy store of a hybrid or electric vehicle is provided. The system includes a receiver which is designed to receive state information of the drive energy store, the state information specifying whether a defect is present or imminent in the drive energy store; and a charging controller, which is designed to adjust a maximum charging voltage and/or a maximum state of charge for a charging process of the drive energy store by a recovery mechanism and/or a load point shift and/or an external charging station to a reduced value if the state information indicates that the defect is imminent.
