NF 5KW EV Coolant Heater Supplier
Description
High-voltage coolant heaters (HVCH) were originally developed to heat ethylene glycol in electric vehicle HVAC modules to ensure optimal cabin comfort. Today, their use has expanded to include battery preheating, an essential function in cold climates that helps maintain EV performance and range. As China's leading automotive PTC heater supplier, NF offers customized products to meet customer requirements.
Key factors in selecting an HV PTC heater
1. Voltage level matching:
Make sure the heater supports your system voltage, such as a 400V or 800V battery platform.
2. Power requirements:
Select the power based on the size of the vehicle interior and the heating speed requirements. The common range is 3kW to 15kW.
3. Heating method:
Water heating type: heats the coolant, suitable for the vehicle thermal management system.
Air heating type: directly heats the air, suitable for rapid cabin heating.
3. Control and communication interface:
Supports communication protocols such as CAN/LIN, which facilitates integration with the vehicle system.
4. EMC performance:
Excellent electromagnetic compatibility design can reduce interference and improve system stability.
5. Safety and protection mechanism:
With over-temperature protection and short-circuit tolerance, it improves safety in use.

FAQ
1. What is EV 5KW PTC Coolant Heater?
EV PTC coolant heater is a heating system specially designed for electric vehicles (EV). It uses a positive temperature coefficient (PTC) heating element to heat the coolant circulating in the vehicle's heating system, providing warmth to passengers and defrosting the windshield during colder months.
2. How does the EV 5KW PTC coolant heater work?
EV PTC coolant heater uses electric energy to heat the PTC heating element. The heating element in turn heats the coolant that flows through the vehicle's heating system. The warm coolant then circulates to a heat exchanger in the cabin, providing heat to the occupants and defrosting the windshield.
3. What are the benefits of using EV 5KW PTC coolant heater?
The EV PTC Coolant Heater has several advantages including:
- Improved cabin comfort: The heater quickly heats up the coolant, allowing passengers to enjoy a warm and comfortable cabin in cold temperatures.
- Efficient heating: PTC heating elements efficiently convert electrical energy into heat, increasing heating performance while minimizing energy consumption.
- Defrost Capability: The heater effectively defrosts the windshield, ensuring clear vision for the driver in frosty conditions.
- Reduced energy consumption: The heater only heats the coolant and not the entire cabin air, helping to optimize energy use and help improve the overall efficiency of the vehicle.
4. Can the EV 5KW PTC coolant heater be used for all electric vehicles?
Electric vehicles equipped with liquid heating system are compatible with EV PTC coolant heater. However, compatibility and installation requirements specific to your vehicle model must be checked.
5. How long does it take for the EV 5KW PTC coolant heater to warm up the cab?
Warm-up time may vary depending on outside temperature, vehicle insulation and desired cabin temperature. On average, the EV PTC coolant heater provides noticeable cabin warmth within minutes.
