The safety of the charging cable is mainly reflected in two aspects
Jul 30, 2023
What are the two main aspects of the safety of the charging cable? Xiamen Nankong Electric to help you answer?
1. Safety of mechanical properties
(1). In the selection of materials
The charging gun should have strict requirements for the plastic material of the gun body, and must have the requirements of different environments such as high temperature resistance and low temperature.
(2). It is a requirement for the cable, which not only needs to have certain restrictions on the diameter of the cable and the thickness of the film, but also passes tests such as high temperature resistance and aging resistance to ensure that it is used for a long time without oxidation.
(3). The requirements for the entire structural design of the charging gun, if the design is unreasonable, may not cause intuitive impact in the short term, and once after long-term wind and sun and other environmental damage, its brittleness will gradually become prominent. "It may be easy for the charging gun to break when it falls on the ground, and this will bring psychological fear to the user, and even the user will question the safety of all charging cables in a partial way." The structural design of the charging gun should be done in strict accordance with the national standard, which is an important issue to be considered outside the standard. ”
2. Safety of electrical performance
It is mainly reflected in the reliability of the metal terminals inside the charging gun. The reliability of the terminal directly determines the tightness of the charging interface, and the tightness will bring two direct effects, one is that the temperature rise of the charging gun during the connection process, and at the same time will cause the heating of the cable, causing unsafe hidden dangers; The second is reflected in the tightness of the terminal coating, if the tightness is not reasonably designed, it will cause the interface to be too loose or too tight when plugging and pulling the charging gun, "repeated tens of thousands of times or even tens of thousands of times of plugging and unplugging, the plating is not well treated, it is easy to be oxidized and worn", which will directly affect the use effect of the charging gun, as well as the safety of the entire charging process. In addition, the processing of the entire charging gun mold must undergo strict heat treatment and related 21 inspection tests.
