What are the common faults of small DC charging guns and how to solve them?

- The charging gun cannot be inserted or unplugged: There may be dirt or foreign matter on the interface, or the charging gun does not match the interface. The solution is to clean the interface and the charging gun plug to ensure that there are no foreign matter; if it does not match, replace the appropriate charging gun.

- Unable to charge normally: The reason may be line fault, fuse blown, charging pile fault, etc. First check whether the charging line is damaged or short-circuited, whether the fuse is blown, and if there is a problem, replace the corresponding parts; if it is not a line and fuse problem, contact the charging pile operator to repair the charging pile.

- The charging process is interrupted: It may be poor contact, battery failure, over-temperature protection, etc. Check whether the connection between the charging gun and the interface is firm; if there is a problem with the vehicle battery, the vehicle needs to be repaired; if it is over-temperature protection, wait for the device to cool down before trying to charge.

- The charging gun leaks electricity: Stop using it immediately. This may be due to internal circuit damage or component damage. Contact a professional for repair in time.
