What is a Liquid Cooled Split Charging Terminal, and what are its main advantages compared with traditional air-cooled charging equipment?

Traditional air-cooled charging piles rely on fans to dissipate heat. When operating at high power, they produce loud noise and are easily affected by dust, sand and moisture. Dust accumulation inside the modules will gradually reduce heat dissipation efficiency and shorten service life. In contrast, liquid cooling brings prominent benefits. First, it supports ultra-high output power, commonly ranging from 250kW up to 720kW. The liquid cooled charging gun and cable have lower temperature rise even under continuous high-current operation, so the cable can be made lighter and more flexible for users to operate easily. Second, the sealed liquid cooling circuit prevents dust and water from entering core power units, greatly lowering failure rates and extending equipment service life. The running noise is much quieter because high-speed cooling fans are largely removed.

In the split structure, the heavy power conversion modules are centrally placed in the power cabinet, while only compact charging terminals are arranged beside parking spots. This layout saves space at charging bays and facilitates centralized maintenance of power cabinets. Operators can deploy multiple charging terminals sharing one centralized power cabinet with dynamic power allocation. When one vehicle finishes charging, the system redistributes idle power to other connected EVs to improve power utilization rate. This charging terminal is widely used in large charging stations, highway super charging stations, commercial vehicle depots and heavy-duty EV charging hubs. It carries comprehensive safety protection including overvoltage, undervoltage, overcurrent, leakage, overtemperature and liquid leakage monitoring. With high reliability and great power scalability, liquid cooled split charging terminals have become the preferred solution for large-scale high-power charging infrastructure projects.
