High Voltage Coolant Heater (PTC heater)for Electric Vehicle( HVCH) W15

Short Description:

The electric High Voltage Heater (HVH or HVCH) is the ideal heating system for plug-in hybrids (PHEV) and battery electric vehicles (BEV). It converts DC electric power into heat with practically no losses. Powerful similar to its namesake, this high-voltage heater is specialized for electric vehicles. By converting electrical energy of battery with DC voltage, ranging from 300 to 750v, into abundant heat, this device provides efficient, zero-emission warming-all throughout the interior of the vehicle.

Product Details

Our high-voltage coolant heaters can be used for improving battery energy performance in EVs and HEVs. In addition it allows comfortable cabin temperatures to be generated in a short time enabling a better driving and passenger experience. With high thermal power density and fast response time due to their low thermal mass, these heaters also extend pure electric driving range as they use less power from the battery.
The heater is mainly used to heat the passenger compartment, defrost and demist the windows, or preheat the power battery thermal management battery, and meet the corresponding regulations and functional requirements.
The main functions of the high voltage coolant PTC heater(HVH or HVCH) are:
-Control function: the heater control mode is power control and temperature control;
-Heating function: convert electric energy into heat energy;
-Interface functions: energy input of heating module and control module, signal module input, grounding, water inlet and outlet.

Powerful, Efficient, Fast
These three words perfectly describe the electric High Voltage Heater (HVH).
It is the ideal heating system for plug-in hybrids and electric vehicles.
The HVH converts DC electric power into heat with practically no losses.

Technical advantages
1.Powerful and reliable heat output: fast and constant comfort for the driver, passengers and battery systems
2. Efficient and rapid performance: longer driving experience without wasting energy
3.Precise and stepless controllability: better performance and optimized power management
4.Fast and easy integration: easy control via LIN, PWM or main switch, plug & play integration


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.
