The Automotive Electric PTC Coolant Heater is the ideal heating system for plug-in hybrids (PHEV) and battery electric vehicles (BEV). It converts AC electric power into heat with practically no losses.


Powerful similar to its namesake, this Automotive Electric PTC Coolant Heater is specialized for electric vehicles. By converting electrical energy of battery with AC voltage220v, into abundant heat, this device provides efficient, zero-emission warming-all throughout the interior of the vehicle.


This Automotive Electric PTC Coolant Heater is suitable for electric / hybrid / fuel cell vehicles and is mainly used as the main heat source for temperature regulation in the vehicle. Automotive Electric PTC Coolant Heater is applicable to both vehicle driving mode and parking mode. In the heating process, electric energy is effectively converted into heat energy by PTC components. Therefore, this product has faster heating effect than internal combustion engine. At the same time, it can also be used for battery temperature regulation (heating to working temperature) and fuel cell starting load.

(1) Efficient and rapid performance: longer driving experience without wasting energy

(2) Powerful and reliable heat output: fast and constant comfort for the driver, passengers and battery systems

(3) Fast and easy integration:Rrelay Control

(4) Precise and stepless controllability: better performance and optimized power management

Users of electric vehicles don't want to go without the comfort of heating that they are used to in combustion engine vehicles. That's why a suitable heating system is just as important as the battery conditioning, which helps to extend service life, reduce charging time and increase range.

This is where the third generation of NF high voltage PTC heater comes in, providing the benefits of battery conditioning and heating comfort for special series from body manufacturers and OEMs.

CE certificate



It is mainly used for cooling the motors, controllers and other electrical appliances of new energy vehicles (hybrid electric vehicles and pure electric vehicles).
