Charging an Electrical Energy Store on an Electric Vehicle at a Socket with Reduction of the Charging Current After Failure and Restoration of the Power Supply
First Claim
Patent Images
1. A method for charging an electrical energy storage device of an electric vehicle at a power socket which serves as a power supply, the method comprising the act of:
- following a failure of the power supply and a subsequent restoration of the power supply, using a charging current, which is automatically reduced compared to the charging current before the failure of the power supply, to charge the electrical energy storage device.

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.

12. An electric vehicle, comprising:
-
an electrical energy storage device which is chargeable at a power socket which serves as a power supply, wherein the vehicle has a variable charging current limit for the purpose of limiting a maximum charging current, and the vehicle is configured to automatically reduce the charging current limit following failure of the power supply.

13. A control device for a charging cable fitting for the purpose of charging an electric vehicle at a power socket, wherein the control device is configured to save a reduced charging current limit, for the purpose of limiting the charging current, prior to a failure in the power supply, such that the saved, reduced charging current limit is used for the purpose of limiting the charging current for the charging process following restoration of the power supply.
