BorgWarner has announced three major business wins for its High Voltage Coolant Heater (HVCH) technology strengthening its footprint in the electric vehicle (EV) markets of China, Korea, and Japan. The deals, with production starts set over the next few years, mark significant steps in the company’s ambition to support electric vehicle manufacturers across Asia with efficient reliable thermal management solutions that enhance EV performance and comfort.
In China, a prominent domestic automaker has selected BorgWarner’s HVCH for its new battery electric SUV with production scheduled to begin in the second quarter of 2025. BorgWarner’s coolant heater will play a crucial role in this SUV, ensuring optimal battery temperature management to improve energy efficiency and extend driving range, two critical factors in China’s competitive automotive landscape.
Similarly in Korea, a leading EV manufacturer has chosen BorgWarner’s HVCH for its upcoming electric pick-up truck model with production expected to commence in early 2025. BorgWarner’s technology will be instrumental in managing cabin temperature and battery performance, enhancing the overall driving experience in a vehicle designed for both utility and passenger comfort. The decision reflects a broader trend among Korean automakers to integrate advanced thermal management solutions that offer both efficiency and energy savings in increasingly diverse EV models.
In Japan, BorgWarner has secured its first HVCH contract with a Japanese automaker marking a milestone in the company’s expansion into Japan’s EV market where competition is rising amid surging interest in electric mobility. Production for this project is planned to begin in 2028. The HVCH technology, known for its compact, modular design, will support cost-efficient, high-performance thermal management tailored to meet the evolving needs of Japan’s automotive industry, which is under pressure to enhance battery efficiency and lower emissions in line with national climate goals.
The HVCH units are built with a compact, modular structure that minimises size and weight, a crucial advantage in electric vehicles where space and energy efficiency are key concerns. By promoting uniform temperature distribution within the battery pack, BorgWarner’s HVCH technology helps improve battery energy performance and extend driving range. Additionally, the heater’s high thermal power density and low thermal mass enable rapid cabin heating and reduce power draw from the battery, directly benefiting energy consumption and driving comfort.
BorgWarner’s HVCH technology utilises Thick Film Element (TFE) technology, allowing flexible heating element design that meets diverse EV requirements. Operating across a wide power range of 3 to 10 kW and supporting supply voltages between 250 and 800 volts, the HVCH is engineered to serve a broad array of applications in both battery electric and hybrid vehicles. By immersing the heating elements in coolant, BorgWarner achieves efficient heat transfer, meeting demands for rapid heat generation and optimising overall EV performance.
