u.s.a. standard type 1 charging connector

Introduction：

When new energy vehicles charge the battery, the charging gun is a necessary accessory. Since the charging current standards of new energy vehicles have not been unified at this stage, the current overload during charging is prone to safety hazards, and even lead to serious battery explosions. At the same time, in the direction of the safety system, the existing charging guns control the current by detecting the temperature of the charging gun through the algorithm of the control system, etc., but this system control method has certain limitations. And so on, it is very easy to cause program errors to cause failure. On the other hand, because the inside of the charging gun is directly connected to the charging pile through a cable, the charging connector is always in a charged state, which is also an important safety hazard. Although the existing charging connector is conductive The outside of the chip is wrapped with insulating rubber to avoid electric shock. However, the aging of the rubber still cannot avoid the occurrence of electric leakage, especially for charging piles that use alternating current. Once electric leakage occurs, it will cause serious safety accidents. Similarly, if Controlling only through the program algorithm has certain limitations. Compared with the program algorithm, modifying the internal mechanical structure of the charging gun can further improve the safety of the charging gun.
