Which is the best thermal solution for super charging pile

    In recent years, domestic new energy vehicle companies have launched 800V high-voltage platform models, achieving a qualitative leap in energy replenishment speed. The accompanying problem is that the energy replenishment anxiety is shifting from the vehicle end to the pile end, and the construction of high-power fast charging piles and stations is urgent.

    At present, the high-power charging station technology in the industry mainly adopts three types: air cooling, liquid cooling, and natural heat dissipation. The air-cooled charging station adopts forced ventilation for heat dissipation, and the air is sucked in and guided to the inside of the charging station through a fan, taking away the heat and discharging it. The air cooling method has the advantages of simple structure and low cost, but the heat dissipation efficiency is relatively low, the fan noise is loud, and there may be insufficient heat dissipation in high-temperature environments. Therefore, air-cooled charging stations are more common in small devices and low-power applications.

    Liquid cooling technology uses liquid as a heat transfer medium and sets up a dedicated liquid circulation channel between the cable and the charging gun. The cooling liquid used for heat dissipation is added to the channel, and the cooling liquid is circulated through a power pump to carry out the heat generated during the charging process. Liquid cooling technology has high heat dissipation efficiency and is suitable for high-power fast charging scenarios.

  The natural cooling series charging station has unique craftsmanship, innovative cooling methods, selected high-quality electronic components, and patented natural cooling modules, achieving intelligent temperature control and silent operation. Due to its heat dissipation structure, which does not require additional cooling equipment and materials, it not only reduces manufacturing costs, but also has high stability and reliability, and low operation and maintenance costs.

    Generally speaking, the speed comparison of charging stations needs to consider multiple factors, including the power of the charging station, charging method, battery capacity, etc. The cooling efficiency of air-cooled charging stations is relatively low, and the charging speed is slow. However, the cost of air-cooled charging stations is low, so they still have certain advantages in some ordinary charging scenarios. Liquid cooling technology has high heat dissipation efficiency, with a charging efficiency of up to 95%. The cooling system also takes up less space and has lower noise. Although it has high operating costs, it is still a better choice for high-voltage charging platforms.
