How to use and maintain the on board charger of electric vehicle ( 2 )
As the professional manufacturer of the on board charger, we are "very responsible" and "must" explain to customers how to ensure the safety of charging lines.
Mainly the following points
① Ensure that the diameter of household main wire is not less than 4mm2 and is national standard copper wire; In case of national standard aluminum wire, it shall not be less than 6 mm2 (under normal conditions, 5-6A current per square of copper wire and 3-4A current per square of aluminum wire);
② The copper wire diameter of charging plug-in wire shall not be less than 2.5 mm2, and the aluminum wire diameter shall not be less than 4 mm2, such as 60v30a charger , AC current 11a. Some car factories force users to arrange electric vehicle charging lines separately and meet the above requirements. I think it is very necessary.
③ 32A leakage protection switch shall be installed in the main wire entering the home; The electric vehicle charging line shall be equipped with a leakage protection switch consistent with the charger power; The high-quality 16a and 3C certified plug-in is selected for the charging plug-in, which is not the plug-in sold at the stall for a few yuan
④ The charging plug , socket, charging gun and charging base are vulnerable devices. They should be regularly checked for damage or aging. If there are problems, they should be replaced in time.
