Control temperature of DC charging connection of electric vehicle charging pile

China [CN]

At present, with the widespread popularization of new energy vehicles, further development involves three major issues related to electric vehicles. One is the driving range, the second is the breakthrough of key charging technology, and the third is the reasonable layout of charging facilities and their safety. At present, the solution to the former is basically clear, but the safety of charging involves a wide range of aspects. However, as the core area of ​​charging, DC charging stations are bound to put forward higher requirements for charging gun products. When charging, the charging gun cannot be charged in time due to excessive temperature, which will lead to safety problems such as burning of the charging gun. So what is the temperature of the DC charging gun generally monitored by?

For the temperature control of the electric vehicle charging gun itself, it is mainly to detect the temperature of the charging gun by setting a temperature sensor in the charging gun, and to control the temperature of the charging gun by using the characteristics of temperature sensors such as NTC thermistors. This temperature measurement method is easy to install, has high accuracy, and also has the advantages of high stability.

The liquid-cooled charging gun in the DC charging gun can reduce the risk of overheating during charging. This is mainly because the liquid cooling mechanism in the liquid-cooled charging gun can effectively dissipate heat, thereby preventing key components in the charging gun from reaching dangerous temperatures. It is by maintaining optimal working conditions that they can effectively alleviate the safety hazards caused by overheating and ensure the safety of electric vehicle charging.
