7kw High Voltage Coolant Heater for Electric Vehicles
Product Description
This high-voltage liquid 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.
The electric 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.
