Developed for pure electric commercial vehicles, this system integrates battery thermal management, electric drive cooling, and cabin air conditioning through an integrated design. It employs intelligent multi-way valve control technology and a modular architecture to achieve cross-domain thermal coordination and efficient waste heat recovery. Not only does it significantly reduce system energy consumption, but it also enhances the filling efficiency by 35% through the industry’s first micro-bubble exhaust technology, providing a more energy-efficient, reliable, and intelligent thermal management solution for new energy commercial vehicles.
Through highly integrated design, the system is compact and easy to install, reducing the number of piping connections and components, which lowers installation difficulty and maintenance costs. Compared to distributed design, it can reduce connections by 30%, further reducing the risk of system leakage. Additionally, integrated design facilitates unified management and maintenance, improving repair efficiency.
By integrating the thermal management circuits of the battery, motor, and air conditioning systems, the system achieves coordinated heat utilization. Through the switching of a four-way reversing valve, it ensures rational distribution of cooling capacity. It also features an automatic exhaust valve, which improves the exhaust efficiency of the coolant circulation circuit by 35% under the same conditions.
The system uses a frequency conversion control logic for the compressor, which automatically adjusts the speed based on the temperature inside the cabin, achieving energy savings while ensuring cooling effectiveness. It employs CAN communication to enable network control, allowing users to view backend data via a mobile app. The unit also has a self-diagnostic function for faults, enhancing safety and reliability.
In response to the increasing battery capacity and the growing cooling demands of batteries, the dual system solution can better protect the normal operation of the battery and extend its service life, providing customers with a better experience.
