What are the two main aspects of charging gun safety?The editor of car charging gun is recommended as follows:
1. Safety of mechanical properties
(1) in the selection of materials
Charging gun should have strict requirements on the plastic material of the gun body. It must have requirements of different environments such as high temperature resistance and low temperature resistance.
(2). It is a requirement for the cable. Not only the diameter size of the cable and the thickness of the film shall be limited to a certain extent, but also the cable shall undergo tests such as resistance to high temperature and aging to ensure that it will be used for a long time without oxidation.
(3) the requirements for the entire structure design of the charging gun, if the design is not reasonable, may not have any direct impact in the short term, but after long-term environmental damage such as wind, sun and sun, its brittleness will gradually emerge."It's possible that a charging gun could easily fall to the ground and break, which could lead to psychological fear among users, who may even question the safety of all charging guns in general.The structural design of the charging gun should be done in strict accordance with national standards, which is an important issue to consider outside the standards.
2. Safety of electrical performance
It is mainly reflected in the reliability of the metal terminal inside the charging gun.The reliability of the terminal directly determines the tightness of the charging interface, and tightness will bring two direct effects. First, the charging gun will rise in temperature during the connection process, and at the same time, it will cause the heating of the cable, resulting in unsafe risks.2 it is embodied in the terminal plating on the tightness of if tightness design is unreasonable, can cause the charging plug, pull out a gun, the interface is too loose or too tight, "repeated thousands of times even tens of thousands of times of insertion, coating without handle, it is easy to oxidation and wear and tear", which directly affect the use effect of charging gun, and the safety in the process of the charge.In addition, the processing of the entire charging gun mold is subject to strict heat treatment and a total of 21 related tests.
