• BorgWarner to supply the entire system, including the eFan, e-motor and integrated inverter
• Start of production slated for Q4 2025
• Acquisition of Drivetek AG in December 2022 supported new business win

BorgWarner has been chosen by a global commercial vehicle OEM to provide its high-voltage eFan system for use in the European and North American markets. This is the first time that BorgWarner has secured an eFan system business in North America and is calling it the first global win in the eFan high-voltage, low-power segment. The eFan system, which can be applied to battery-electric and fuel-cell electric vehicles, will be installed on the OEM’s heavy-duty battery-electric trucks to meet the highest cooling requirements and deliver superior performance. BorgWarner will supply the complete eFan R10 system, which includes a fan, e-motor, and integrated high-voltage inverter capable of producing up to 10 kW power and 40 Nm torque within a temperature range of minus 40 to 80 degrees Celsius.

“BorgWarner has applied its expertise in fan performance, electric motors and power electronics to develop highly efficient eFan systems for a range of electric vehicles,” said Joe Fadool, President and General Manager, BorgWarner Emissions, Thermal and Turbo Systems. “We are pleased to extend our work with this global OEM to the supply of our high-performance eFans, further supporting our sustainability strategy to create a cleaner, more energy-efficient world,” added Fadool.

BorgWarner’s eFan system is designed to be compatible with a range of high-voltage commercial vehicle electrical systems, with an operating voltage range from 600V to 850V without derating. The company said that electric motors and power electronics are liquid-cooled for durability and compactness, ensuring long-term reliability. The fans are optimized for low speeds, offering high efficiency and minimal noise during battery charging. BorgWarner’s eFan portfolio includes high-voltage options for both low- and high-power segments, with a modular design that allows for scalability and varying power levels from 5 kW and 20 Nm torque to 40 kW and 160 Nm. Customers can choose from open fans or ring fans, as well as external or integrated inverters, with scalable components and tailored interfaces and connectors to meet specific requirements. In December 2022, BorgWarner acquired Drivetek AG to enhance the company’s inverter expertise and capabilities, supporting the growth of its eFan business. Production is expected to begin in Q4 2025, with initial volumes exceeding 3,000 and rising to nearly 74,000 by 2031 across North America and Europe.
