Thick Film Liquid Heaters in the Future New Energy Vehicle Market

Thick Film Liquid Heaters in the Future New Energy Vehicle Market

With the rapid growth of the new energy vehicle (NEV) industry, efficient and reliable heating solutions are in high demand. Thick film liquid heaters are emerging as a superior alternative to traditional PTC heaters, offering significant advantages in energy efficiency, longevity, and performance, making them highly suitable for future NEV applications.

Advantages of Thick Film water Heaters Over PTC Water Heaters

1. Higher Thermal Efficiency (97% vs. 90%)

   • Thick film heaters convert 97% of electrical energy into heat, reducing energy waste and improving battery range in EVs.

   • PTC heaters typically have around 90% efficiency, making them less optimal for energy-sensitive applications.

2. Longer Lifespan (30,000 hours vs. 15,000 hours)

   • Thick film technology ensures double the service life compared to PTC heaters, reducing replacement costs and maintenance needs.

   • This makes them ideal for long-term use in electric vehicles, where durability is critical.

3. Faster Heating & Precise Temperature Control

   • Thick film heaters achieve instant heating with rapid thermal response, improving cabin comfort and defrosting efficiency.

   • Their uniform heat distribution prevents local overheating, enhancing safety and reliability.

4. Compact & Lightweight Design

   • Thick film heaters are smaller and lighter than PTC heaters, helping reduce vehicle weight and optimize space utilization.

5. Lower Energy Consumption

   • Due to their higher efficiency, thick film heaters consume less power, which is crucial for extending EV range in cold climates.

Future Prospects in the NEV Market

As automakers focus on energy efficiency, fast heating, and longer battery life, thick film liquid heaters are expected to gradually replace PTC heaters in:

• Battery thermal management systems (maintaining optimal battery temperature)

• Cabin heating & defrosting (improving passenger comfort)

• Heat pump-assisted systems (enhancing overall HVAC efficiency)

With advancements in material science and manufacturing processes, thick film heating technology will likely become a standard solution in next-generation electric vehicles, contributing to higher energy savings and sustainability.
