The liquid cooling system mainly includes radiator, liquid cooling plate, water pump and cooling oil. Liquid-cooled charging piles are widely used in high-power DC fast charging equipment to meet the charging needs of high-performance electric vehicles. The system adopts a liquid-cooled power cabinet design, which has a built-in liquid-cooled charging module. The heat is transferred to the heat dissipation cabinet through liquid cooling pipes, and it has the characteristics of high protection and low noise. Intelligent charging process control and perfect charging process monitoring and protection, real-time collection and display of vehicle battery information charging status information; there are multiple options such as timed charging, quantitative charging, fixed amount charging and automatic full charging; the flexible shared charging pile adopts fast charging technology to support various types of batteries.
