BorgWarner has secured contracts with two major global original equipment manufacturers to supply high-voltage coolant heater (HVCH) technology for plug-in hybrid electric vehicle platforms, with production scheduled to begin in 2028.
The contracts include a 400V technology deployment across one OEM's PHEV platforms and an 800V HVCH system for another global OEM's light PHEV platforms, including a pick-up truck. One contract marks BorgWarner's first eHeater win for a hybrid program with the respective legacy automaker.
The HVCH technology enhances vehicle cabin and battery heating, improving overall driving experience and system performance. The system includes a resistive heating element and smart controller for efficient heat transmission to coolant, enabling heating in cold conditions.
BorgWarner's HVCH features a compact, modular design that minimizes size and weight. The technology delivers low thermal mass, high power density and efficiency for faster heating and cooling. It optimizes battery temperature and supports fast charging by maintaining ideal thermal conditions.
The heating elements are designed for durability, lasting over 15,000 hours with anti-vibration properties and non-flammable characteristics. The system includes functional safety concepts with automatic shutdown capabilities if issues are detected.
"Securing these contracts is a milestone for our company and validates our technology leadership and expertise in battery and cabin heating," said Dr. Volker Weng, Vice President of BorgWarner Inc. and President and General Manager, Turbos and Thermal Technologies. "We value our strong relationships with both automakers, one marking our first BorgWarner eHeater win with the company and the other building upon our existing partnership through the expanded supply of our HVCHs on additional vehicle platforms."
The contracts expand BorgWarner's presence in the hybrid vehicle market as the automotive industry continues transitioning toward electrification.
