Abstract

A method is provided for charging an electrical energy store on an electric vehicle at a socket providing a power supply, particularly a single-phase 230 V or 120 V domestic socket. The charging current used to charge the electrical energy store after failure and subsequent restoration of the power supply is automatically reduced over the charging current prior to failure of the power supply.
