Abstract: The invention relates to a method for charging an electrical energy store, the electrical energy store comprising at least one electrical energy storage unit and a predefined maximum permissible energy-store voltage limit value being specified for the electrical energy store. The electrical energy store is charged with a pulsed charging voltage, a maximum value of the pulsed charging voltage being greater than the predefined maximum permissible energy-store voltage limit value over a pulse duration in the case of at least one pulse. The invention further relates to a corresponding device for charging the electrical energy store, to a corresponding computer program, to a corresponding machine-readable storage medium and to a corresponding electrical energy store.

Abstract: A battery system (10) for use on a vehicle electrical system (50) of a motor vehicle, comprising a negative pole (21), a positive pole (22), a battery module (5) and a switching unit (60) that has at least one actuatable switch and a current sensor (65) for measuring a battery current (IB) flowing through the battery system (10) is disclosed. The switching unit (60) is operable in a safety mode in which the at least one switch and the current sensor (65) interact such that the battery current (IB) is limited to a prescribed maximum value or is interrupted for a prescribed maximum period of time if the battery current (IB) exceeds a prescribed limit value and hence starting of the motor vehicle is prevented.
