BorgWarner Secures Global Hybrid EV Heater Contracts

Auburn Hills Michigan-BorgWarner., a global leader in sustainable mobility and automotive technology, has secured contracts with two major OEMs to supply its high-voltage coolant heater (HVCH) technology for plug-in hybrid electric vehicles (PHEVs). This development highlights the growing importance of thermal management solutions in electrified mobility.

First-Time Entry and Expanded Partnership
One of the contracts represents BorgWarner’s first eHeater program with a legacy hybrid vehicle automaker, marking a strategic expansion into new hybrid platforms. The second contract builds on an existing partnership with a different OEM, integrating HVCH across several light PHEV platforms, including pick-up trucks. Both programs are expected to begin production in 2028, with BorgWarner supplying 400V and 800V HVCH units tailored to each application.

HVCH Technology Advantages
BorgWarner’s high-voltage coolant heaters are designed for efficient cabin and battery heating, particularly in cold climates. The units feature:

BorgWarner’s high-voltage coolant heaters feature a compact and modular design to minimize size and weight, while resistive heating elements with smart controllers ensure precise and efficient heat transfer. The units offer low thermal mass and high power density, enabling faster heating and cooling, and provide battery thermal optimization to support faster EV charging. Built for long-lasting durability with heating elements rated over 15,000 hours, the HVCHs also include robust safety features, such as anti-vibration construction, non-flammability, and automatic shutdown in case of overheating.

These features not only enhance passenger comfort, but also maintain optimal battery temperature, ensuring system performance and longevity a critical consideration for hybrid vehicles operating in diverse climates.

Strategic Importance for OEMs
Thermal management has become a key differentiator in the hybrid and EV markets. By integrating BorgWarner’s HVCH technology, OEMs can deliver enhanced driving experience, energy efficiency, and faster charging, which are increasingly critical factors for consumer adoption. The contracts also reinforce BorgWarner’s position as a technology leader in electrified vehicle thermal solutions, helping OEMs meet both performance and sustainability goals.

Looking Ahead
As the hybrid EV market continues to expand, innovative thermal management systems like BorgWarner’s HVCH will play a central role in shaping the performance, safety, and comfort standards of next-generation electrified vehicles.

Race Perspective:
This development reflects a broader trend where OEMs are investing in advanced thermal solutions to improve battery life, optimize charging, and elevate passenger experience. Companies like BorgWarner that can deliver reliable, efficient, and scalable solutions are well-positioned to capture growth in the electrified mobility market.
