What is the reason for the heat of the new energy EV charging plug
The reasons for the heating of the new energy EV charging plug:
1. The plug of the EV charging plug is loose and the contact surface is oxidized: the plug is loose and the contact surface is oxidized, which will lead to poor contact during charging. If there is loose contact contact during charging, the voltage between the contacts is sufficient to break down The air gap thus forms an arc, which sparks so that it ignites nearby combustibles and creates a fire. If the charging socket is not connected firmly, poorly maintained, and a poorly conductive oxide film will be formed on the joint during long-term operation, the oxidation of the charging plug will easily cause excessive contact resistance and cause the plug to overheat.
2. There is a problem with the electronic lock of the charging socket of the EV charging plug: In terms of the charging socket, the model and size of the charging port are uniform, and the vehicle charging socket has corresponding regulations on safety requirements such as current, and the charging socket should be equipped with an electronic locking device to prevent Accidental disconnection during vehicle charging. When the electronic lock is locked, the charging socket may continue to charge, causing the charging socket to overheat.
3. There is a problem with the quality of the charging socket of the EV charging plug: due to the different materials of the battery core, the charging socket will heat up when the current is too large. However, different materials have different heat dissipation properties. If the material is not good, it will lead to poor heat dissipation and heat generation.
