NF 0.5-3kW PTC High Voltage Heater for EV Car or BTMS

Introducing our High voltage coolant heaters— engineered for high-performance electric vehicles (EVs) to deliver precise thermal management, enhanced energy efficiency, and superior cabin comfort. As global EV adoption accelerates, reliable, low-power-consumption heating solutions capable of consistent operation across extreme ambient temperatures have become critical. Our EV coolant heaters are purpose-built for integration into modern EV architectures, providing intelligent temperature regulation for both battery packs and passenger cabins.

Leveraging advanced PTC (Positive Temperature Coefficient) ceramic heating elements and closed-loop liquid thermal management, these heaters achieve rapid thermal response—reducing warm-up time by up to 40% compared to conventional systems. Maintaining battery cells within their optimal temperature range (typically 20–35°C) not only maximizes charge/discharge efficiency and regenerative braking performance but also mitigates capacity degradation, thereby extending battery service life and total cost of ownership.

Safety and long-term reliability are foundational to our design philosophy. Each unit undergoes rigorous validation—including IP67 ingress protection testing, vibration endurance per ISO 16750-3, and thermal cycling over 10,000 cycles—and is constructed using aerospace-grade aluminum housings and UL-certified insulation materials. The modular, CAN-enabled design ensures plug-and-play compatibility with major EV platforms and simplifies OEM integration or aftermarket retrofitting.

Beyond functional performance, the system enhances user experience through intelligent pre-conditioning: cabin heating can be scheduled remotely via vehicle telematics, enabling occupants to enter a thermally comfortable environment without drawing power from the traction battery during standstill—thus preserving driving range.

Whether deployed in urban commuter fleets or long-haul applications, our HV coolant heater  represent a mature, scalable, and certified solution aligned with industry standards. Partner with us to advance thermal efficiency, safety, and sustainability in next-generation electric mobility.
