Three-in-One Integrated Thermal Management Controller

600V DC/ 800V DC | Natural Cooling | CAN2.0 | IP67

Product Features

• Highly integrated control system:

  Integrates the low-voltage refrigeration system controller, compressor drive, and high-voltage PTC control into a single unit, reducing costs while enhancing electromagnetic compatibility (EMC) and interference resistance, and minimizing external wiring connections.

  
  

• SiC power devices: 

  Replaces the original IGBT with SiC (Silicon Carbide) power devices, providing higher voltage withstand capability and reducing heat generation.

  
  

• Enhanced connection reliability:

  Replaces conventional connectors with metal cable glands, improving overall reliability and sealing performance.

  
  

• Improved cooling efficiency:

Changes the cooling method of the compressor power module from low-voltage refrigerant cooling to natural air cooling, reducing the risk of compressor-related failures.

• 
  

  Compact and easy to install:
  Features a compact design for easy installation and efficient space utilization.

  
  

• Wide voltage platform compatibility: 

  Supports both 600 V DC and 800 V DC rated vehicle voltage platforms.

  Q: How does a PTC water heater work?

• A: The PTC heater works by passing electric current through PTC ceramic material. The material’s resistance increases as temperature rises, automatically adjusting the heating power to maintain a constant temperature.

• Q: Which vehicle types is it suitable for?

• A: Suitable for most electric buses, electric trucks, and electric construction machinery (excavators, loaders, etc.).

• Q: How does it perform in low-temperature environments?

• A: PTC heaters remain stable in low-temperature conditions, making them ideal for electric vehicles in cold regions.

• Q:  What are the core advantages of EVLINK PTC water heaters?

• A:High reliability, fast and uniform heating, patented thermal expansion control, moisture protection, and exceptional performance under extreme conditions.
