Charging device for electric vehicles and automatic trobleshooting method thereof

1. An automatic troubleshooting method for a charging device of an electric vehicle, comprising:

detecting an operation of the charging device; and

when an abnormal situation specified by a predetermined abnormal situation definition is detected, automatically performing a troubleshooting procedure corresponding to the predetermined abnormal situation definition,

wherein the charging device further comprises a network connection unit, which is configured to enable the charging device to remotely connect to a charging management server via a network connection;

wherein the method further comprises detecting the operation of the network connection unit, and when detecting that the network connection is interrupted, enabling the charging device to perform a cooling procedure first and then enabling the network connection unit to perform a network connection establishment procedure to re-establish the network connection.

2. The automatic troubleshooting method of claim 1 , wherein

the method further comprises detecting the operation of the network connection unit, and when detecting that the network connection is interrupted, enabling the network connection unit to perform a network connection establishment procedure to re-establish the network connection.

3. The automatic troubleshooting method of claim 2 , wherein the method further comprises when detecting that the network connection is interrupted and the network connection has not been restored after the network connection unit has performed the network connection establishment procedure, clearing temporary network information of the network connection unit and enabling the network connection unit to perform the network connection establishment procedure again after clearing the temporary network information of the network connection unit.

4. A charging device of electric vehicles, which performs the automatic troubleshooting method as claim 3 .

5. The automatic troubleshooting method of claim 2 , wherein the method further comprises when detecting that the network connection is interrupted and the network connection has not been restored after the network connection unit has performed the network connection establishment procedure, enabling the charging device to perform a rebooting procedure.

6. A charging device of electric vehicles, which performs the automatic troubleshooting method as claim 5 .

7. A charging device of electric vehicles, which performs the automatic troubleshooting method as claim 2 .

8. The automatic troubleshooting method of claim 1 , wherein

the method further comprises detecting the operation of the network connection unit, and when detecting that the network connection is not interrupted but the network connection unit can't be remotely connected to the charging management server, enabling the network connection unit to perform a server connection procedure to establish a connection with the charging management server.

9. The automatic troubleshooting method of claim 8 , wherein the method further comprises detecting the operation of the network connection unit, and when detecting that the network connection is not interrupted and the network connection unit still can't be remotely connected to the charging management server after the network connection unit has performed the server connection procedure, clearing temporary network information of the network connection unit and enabling the network connection unit to reperform the server connection procedure again to establish the connection with the charging management server after clearing the temporary network information of the network connection unit.

10. A charging device of electric vehicles, which performs the automatic troubleshooting method as claim 9 .

11. The automatic troubleshooting method of claim 8 , wherein when detecting that the network connection is not interrupted and the network connection unit still can't be remotely connected to the charging management server after the network connection unit has performed the server connection procedure, rebooting the charging device.

12. A charging device of electric vehicles, which performs the automatic troubleshooting method as claim 11 .

13. A charging device of electric vehicles, which performs the automatic troubleshooting method as claim 8 .
