Vehicle Thermal Management System (VTMS)

The Vehicle Thermal Management System (VTMS) is an electronic product designed and developed by Hirain to intelligently manage vehicle temperature. The system adjusts the operation of components like pumps, fans, compressors, valves, and dampers based on sensors and environmental parameters (temperature, pressure, light intensity, humidity). This precise control of heating and cooling enhances electric motor thermal management, cabin comfort, and battery thermal management, supporting the intelligent development of new energy vehicles.
