Charging piles are mostly used in public places, etc., so higher requirements are needed for the safety of charging piles. DC charging piles have large charging currents and fast charging speeds and are currently the main fast charging equipment. However, due to the large charging current, the electrical components of the charging pile body will generate a lot of heat when it is running. Excessive temperature can easily cause the charging pile to spontaneously combust, leading to a fire.

[0003] After searching, a charging pile system with big data technology was proposed according to the Chinese utility model application number CN202120182254.5. The control valve is opened to allow the liquid carbon dioxide in the storage tank to enter the discharge nozzle and become gaseous carbon dioxide. The gaseous carbon dioxide will reach the fire extinguishing nozzle through the material guide hose and be sprayed out from the fire extinguishing nozzle. It will be sprayed onto the location where a fire has occurred or is about to occur on the charging pile host, and the corresponding location will be cooled and extinguished, thereby achieving the purpose of fire prevention of the charging pile host. However, after the liquid carbon dioxide in the storage tank is used up, it needs to be replenished. Since the liquid carbon dioxide needs to be stored and transported under low temperature conditions, special equipment and facilities are required to maintain its low temperature state. The operation is complicated and the cost is high, which affects its use. Therefore, a DC charging pile is proposed to solve the above problems. Utility Model Content
