BorgWarner to supply eFans for electric truck

BorgWarner said it has been selected to supply its high-voltage eFan system to a global commercial vehicle OEM for use in both the European and North American markets. This marks the first eFan system business in North America for BorgWarner, as well as its first global win in the eFan high-voltage, low-power segment.

The eFan system, which can be applied to battery-electric vehicles (BEVs) and fuel cell electric vehicles (FCEVs), will be on the OEM’s heavy-duty battery-electric trucks. Start of production slated for the fourth quarter of 2025.

For this project, BorgWarner is supplying its complete eFan R10 system, which includes a fan, e-motor and integrated high-voltage inverter. The eFan R10 is capable of up to 10 kW power and 40 Nm torque with an operating temperature range from -40º to 80º C (-40 º to 176º F).

“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.”

BorgWarner’s eFan system has an operating voltage range from 600 to 850 V without derating, ensuring compatibility with various high-voltage commercial vehicle electrical systems. Designed for long-term reliability, the electric motor and power electronics are liquid-cooled for compactness and robust operation. Additionally, the fans are optimized for low speeds with high efficiency and minimum noise during battery charging, the company said.
