Temperature sensor: complete charging pile
Aug 31 , 2022
The charging pile has a professional term called "over temperature protection", which means that the corresponding protection function is activated when the temperature exceeds a certain threshold. There are many temperature sensors installed in each charging pile. They monitor the temperature in the charging pile at all times. Once they find that the temperature of the device is too high, they wi...
