Electric Vehicle High Voltage Coolant Heater (PTC) Heater (HVCH) W09

Short Description:

High Voltage Electric Heating (HVH or HVCH) is the ideal heating system for plug-in hybrid vehicles (PHEVs) and battery electric vehicles (BEVs). It converts DC electrical energy into heat with virtually no loss. Powerful as its namesake, this high-voltage heater is specialized for electric vehicles. By converting the battery’s electrical energy with DC voltage, ranging from 300 to 750 V, into abundant heat, this device provides efficient, emission-free heating throughout the vehicle’s interior.

Product Details

Our high-voltage coolant heaters can be used to improve the energy performance of electric and hybrid vehicle batteries. In addition, it helps to generate comfortable temperatures in the cabin in a short time, resulting in a better driving and passenger experience. With high thermal power density and fast response time due to their low thermal mass, these radiators also extend pure electric driving range as they use less battery energy.
The heater is mainly used to heat the passenger compartment, defrost and defogge windows, or preheat the thermal management battery of the power battery, and meet the corresponding regulations and functional requirements.
The main functions of PTC High Voltage Coolant (HVH or HVCH) heaters are:
-Control function: the heating control mode is power control and temperature control;
-Heating function: convert electrical energy into thermal energy;
-Interface functions: heating module and control module energy input, signal module input, grounding, water input and output.

Powerful, efficient, fast
These three words perfectly describe High Voltage Electric Heating (HVH).
It is the ideal heating system for plug-in hybrid and electric vehicles.
HVH converts DC electrical energy into heat with virtually no losses.

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




By 2030, electric vehicles (EVs) will constitute 64% of global new car sales. As the greener and more cost-efficient alternative to fossil-fueled cars, EVs will soon be a fixture of everyday life. Therefore, our main new products in recent years are electric vehicle parts, especially High Voltage coolant heater. From 2.6kw to 30kw, our heaters can meet all your requirements.
