Abstract

A method is provided for implementing electric-shock protection in a transformer-free AC charging device (202). The method includes supplying an input end of the AC charging device (202) with alternating current from a charging socket (122), providing the output end of the AC charging device (202) with direct current (106) for charging a high-voltage battery, and using the peripheral charge controller (220) for controlling the charging socket (122). The peripheral charge controller (220) is arranged within a housing of the AC charging device (202).

First claim

What is claimed is:

1. A method for integrating a peripheral charge controller into a non-DC-isolated AC charging device of an electric vehicle, the method comprising using a safety circuit to implement electric-shock protection in the non-DC-isolated AC charging device, arranging the peripheral charge controller within a housing of the AC charging device of the electric vehicle and coupling the peripheral charge controller to a charging socket, supplying an input end of the AC charging device with alternating current from the charging socket, using an output end of the AC charging device for providing direct current for charging a high-voltage battery of the electric vehicle, the peripheral charge controller coupled to the input end and output end of the AC charging device within the housing via a control unit, and using the peripheral charge controller for executing identification of a charging plug disposed in the charging socket and controlling the charging socket based on the identification of the charging plug.

2. The method of claim 1 , further comprising using the peripheral charge controller to monitor a charging socket flap.

3. The method of claim 1 , further comprising using peripheral charge controller for executing charging plug control.

4. The method of claim 1 , further comprising using the peripheral charge controller to execute temperature monitoring.

5. The method of claim 1 , further comprising using the peripheral charge controller for providing different charging standards based on the identification of the charging plug.

6. The method of claim 5 , wherein the charging standards are selected in accordance with a country name or a country charging standard.

7. The method of claim 1 , further comprising using a software module of the peripheral charge controller to act on the AC charging device.

8. A charging system of an electric vehicle, comprising: a non-DC-isolated AC charging device and a peripheral charge controller module arranged within a housing of the AC charging device, wherein the system is configured to execute the method of claim 1 .

9. The system of claim 8 , further comprising a 12 V interface to an actuating system of a charging peripheral.

10. A method for integrating a peripheral charge controller into a non-DC-isolated AC charging device of an electric vehicle, the AC charging device having a housing and the peripheral charge controller being arranged in the housing of the AC charging device, the method comprising:
using a safety circuit to implement electric-shock protection in the non-DC-isolated AC charging device;
coupling the peripheral charge controller to a charging socket;
supplying an input end of the AC charging device with alternating current from the charging socket;
using an output end of the AC charging device for providing direct current for charging a high-voltage battery of the electric vehicle; and
using the peripheral charge controller to:
monitor a charging socket flap,
execute charging plug identification of a charging plug disposed in the charging socket,
control locking of the charging plug in the charging socket; and
controlling the charging socket based on the identification of the charging plug.

11. The method of claim 10 , further comprising using peripheral charge controller for providing different charging standards in accordance with a country name or a region name.

12. The method of claim 1 , wherein the identification of the charging plug includes identifying a voltage level of the charging plug in the charging socket.

13. The method of claim 10 , wherein the charging plug identification includes identifying a voltage level of the charging plug in the charging socket.

14. The method of claim 10 , further comprising using peripheral charge controller for providing different charging standards in accordance with charging plug identification.

15. The method of claim 1 , wherein the identification of the charging plug includes identifying a voltage type of the charging plug in the charging socket.

16. The method of claim 10 , wherein the charging plug identification includes identifying a voltage type of the charging plug in the charging socket.
