BorgWarner has secured a major contract with a global automotive manufacturer to provide its 400-volt High-Voltage Coolant Heater (HVCH) for integration into a variety of plug-in hybrid electric vehicles (PHEVs). This includes several vehicle segments, such as mid-size pickup trucks, sport utility vehicles (SUVs), and minivans. Production is expected to begin in 2027, and the contract marks BorgWarner’s largest HVCH deal for PHEVs in North America, based on projected production volumes.
The 400V HVCH is designed to be compact and versatile, making it compatible with various vehicle types without the need for platform modifications. It features brazed aluminum fin construction and thick-film heating elements, achieving a high thermal power density of up to 10 kW. This design improves heat transfer, coolant flow distribution, and reduces the risk of bubble formation and gas entrapment.
The HVCH system is built to provide consistent thermal energy to both the vehicle cabin and battery, regardless of outside temperatures. By maintaining stable thermal conditions, the system supports faster battery charging, extends battery life, and enhances overall vehicle performance and driving range.
BorgWarner continues to strengthen its position in the electrification market through key partnerships and innovative product offerings. As a global leader in automotive solutions, BorgWarner specializes in powertrain technologies, including turbochargers, transmission systems, and electric vehicle components. The company is committed to sustainability, developing products that improve fuel efficiency, reduce emissions, and boost vehicle performance. Headquartered in Auburn Hills, Michigan, BorgWarner operates worldwide and is at the forefront of advancements in electric and hybrid vehicle technologies.
