  In-House PTC Liquid Heater Manufacturing

  Proprietary R&D and in-house manufacturing ensure product  consistency, reliable quality, and long-term supply stability.

  
  

  
  

The system integrates a compressor, condenser, expansion valve,  plate heat exchanger, coolant pump, fan, ECU controller,  and temperature sensors. During battery charging and discharging, heat generated by the cells  is transferred to the battery cooling plate and carried by  the coolant to the plate heat exchanger.  The refrigerant absorbs the heat and releases it through  the condenser, thereby maintaining a stable  and uniform battery cell temperature.

Applications

The BTMS is widely used in buses and other large vehicles. It consistently creates a comfortable interior environment for passengers, regardless of whether the season is cold or warm. Furthermore, thanks to its compact size and high-performance capabilities, it is the preferred choice for structural engineers when positioning heat sources.
