High Quality High Voltage PTC Electric Heater
New-energy vehicles such as electric cars face one common challenge: driving range loss caused by heating and air-conditioning. Conventional cars reuse waste heat from the engine, but electric and new-energy vehicles have no engine and lack a sufficient heat source. The high-voltage PTC electric heater fills this gap as a dedicated heating solution.

High-quality High Voltage PTC Electric Heater
New-energy vehicles such as electric cars face one common challenge: driving range loss caused by heating and air-conditioning. Conventional cars reuse waste heat from the engine, but electric and new-energy vehicles have no engine and lack a sufficient heat source. The high-quality high voltage PTC electric heater fills this gap as a dedicated heating solution.
Why PTC Heating Matters
The Heating Challenge in Electric Vehicles
Unlike conventional vehicles, which capture free waste heat from the internal-combustion engine to warm the cabin in cold weather, electric and new-energy vehicles have no engine and no such residual heat source. This means every kilowatt of heat used to warm the cabin, battery or interior in winter must come directly from the traction battery.
The consequences are significant: at low ambient temperatures, relying on the battery alone for heating can cut real-world driving range by 20–30%, while battery performance and charging efficiency also drop sharply when the pack is cold. Passenger comfort and daily usability suffer at exactly the moment drivers need them most.
Without engine waste heat, EV cabin and battery warming in winter directly drains the battery. The PTC electric heater supplies high-efficiency heat when it is needed most, protecting driving range and passenger comfort.
The PTC Electric Heater Solution
The high voltage PTC coolant heater was purpose-built to close this gap. Instead of a fixed-resistance heater that wastes energy, it uses positive temperature coefficient (PTC) ceramic heating elements that self-regulate: as the element heats up, its resistance rises automatically, so it draws less current and stabilizes at a set temperature without complex control or overheating.
This delivers three practical advantages for electric, hybrid and fuel-cell vehicles:
- High-efficiency, on-demand heat- heat output matches demand, supplying cabin warming, Battery Thermal Management System For New Energy Vehicles heating, seat heating and rear-view mirror defrosting with minimal wasted energy.
- Range protection- efficient heat delivery means the traction battery spends less energy on heating, preserving range and protecting battery health in cold climates.
- Inherent safety- the self-limiting PTC characteristic prevents thermal runaway and overheating, reducing the load on the vehicle's control and protection systems.
For our NFSR02-12 model, this translates into 7kW rated heating power across a working voltage range of DC250~490V, with a low-voltage control supply of DC 9V–16V, capable of operating across a storage temperature range of -40°C to 125°C. Compact, lightweight and easy to install, it integrates cleanly into a vehicle's thermal-management loop as the primary heat source in both driving and parking modes.
Three Applications, One Heater
Water heating
Cabin coolant circuit warming
Battery heating
Battery thermal management in low temperatures
Energy storage heating
Energy storage thermal systems in low temperatures
How It Works
The PTC heating element warms the coolant in the circulating pipeline through heat exchange. Its positive temperature coefficient makes it inherently self-limiting and safe, with high sensitivity and a wide operating temperature range.
