1. The Importance of Coolant Heating in Electric Vehicles

With the rapid development of electric vehicles, thermal management has become increasingly important for batteries, motors, and electronic control systems. Especially in cold environments, low coolant temperatures can affect battery performance, charging efficiency, and overall vehicle operation.

EV coolant heating systems require heating elements that can provide fast heating, stable performance, and compact design. Thick Film Heater has become an ideal solution for new energy vehicle thermal management applications due to its fast heating response, high efficiency, and excellent reliability.

It is widely used in applications such as battery coolant heaters, motor cooling circulation systems, and other EV thermal management equipment.

2. Structure and Advantages of Thick Film Heater

A Thick Film Heater is generally made by printing resistive materials onto a metal substrate through thick film technology and then sintering them at high temperatures to form a stable heating circuit.

Compared with traditional heating elements, Thick Film Heater offers several advantages:

• Fast heating response: The heating layer is directly integrated with the metal substrate, providing efficient heat transfer.
• Compact design: Its lightweight and thin structure makes it suitable for limited installation spaces in electric vehicles.
• Precise temperature control: Heating power and temperature control solutions can be customized according to customer requirements.
• High reliability: It can withstand long-term operation and demanding automotive environments.

Our Thick Film Heaters are mainly manufactured using 444 stainless steel and 443 stainless steel materials.

These materials provide excellent corrosion resistance, high-temperature stability, and mechanical strength, making them suitable for EV coolant heating applications.
