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.

Method for charging an electrical energy store by means of voltage pulses

A battery system () for use on a vehicle electrical system () of a motor vehicle, comprising a negative pole (), a positive pole (), a battery module () and a switching unit () that has at least one actuatable switch and a current sensor () for measuring a battery current (IB) flowing through the battery system () is disclosed. The switching unit () is operable in a safety mode in which the at least one switch and the current sensor () 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.
