The power of charging piles is getting bigger and bigger. With the increasing power loss of heat energy from charging piles, it is easy for charging piles to overheat. Except for the heat dissipation of the inherent structural materials of the charging piles, there is no other way to dissipate heat, which will cause the power supply circuit of the charging pile to have a drastic reduction in life due to long-term overheating.

When the platform early warning control module detects that the circuit load temperature is greater than or equal to the set threshold, the platform early warning control module sends information to the current control module, and the current control module controls the current output of the charging pile to decrease; The physical cooling module is installed in the charging pile. When the platform early warning control module detects that the circuit load temperature is greater than or equal to the set threshold, the platform early warning control module sends information to the physical cooling module, and the physical cooling module cools the circuit of the charging pile.

[0005] Furthermore, the load temperature detection module is composed of a temperature sensor and a wireless transmission unit.

[0006] Furthermore, the wireless transmission unit is a ZigBee wireless transmission module, and the ZigBee wireless transmission module uploads the temperature information collected by the temperature sensor to the platform early warning control module in a star-shaped or sheet-shaped network topology.

[0008] Furthermore, when the platform early warning control module detects charging abnormality, the abnormal information is uploaded to the cloud platform and a log of the abnormal information is generated.

[0009] Furthermore, the above-mentioned physical cooling module includes a controller and a blower. The air outlet of the blower is toward the circuit load of the charging pile. The controller is interactively connected with the platform early warning control module. When the platform early warning control module detects that the circuit load temperature is greater than or equal to the set threshold, the platform early warning control module sends information to the controller of the physical cooling module, and the controller controls the blower to start.
