EV Coolant Heater

 

 

 

 

EV Coolant Heaters are used to provide heat for the air conditioning systems or battery packs of battery electric vehicles (BEVs) and hybrid electric vehicles (HEVs). They can also supply heat to other vehicle components requiring temperature regulation.

 

Effective thermal management is critical for maximizing the performance and driving range of modern electric and hybrid vehicles. As a smart, fail-safe liquid electric heating solution, the PTC water heater serves as a core component of vehicle thermal management systems. It heats the engine coolant to deliver stable and reliable thermal output for cabin heating and high-voltage battery thermal regulation. Featuring superior safety performance, excellent heat storage capability and seamless compatibility with vehicle HVAC systems, the water-cooled PTC heater has become the mainstream and preferred solution across the automotive industry.

 

 

NF's PTC EV coolant heater fully embodies the performance characteristics of PTC technology.

It utilizes a ceramic PTC heating element for safety and reliability and features a specialized water channel design that ensures high heat exchange efficiency.

 

Equipped with a fully proprietary controller, it integrates multiple functions-including water temperature protection, PCB overheat protection, overcurrent, overvoltage, and undervoltage protection, short-circuit protection, a sleep mode, and stepped power regulation-offering a user-friendly, safe, and reliable solution.
