Sulian Plastics

Connects the battery-pack water-cooling plates with the cooling jackets of the drive motor, reducer, transformer and electronic control unit, enabling continuous coolant circulation. Pipeline distribution and flow design achieve heat exchange, keeping the battery at the set temperature for long periods and ensuring stable operation of the three-electric system and battery safety. Also usable for grid energy-storage module cooling.
