BorgWarner will provide first high-voltage eFan system to a major European commercial vehicle OEM. More into details, the eFan system will be used on battery electric heavy-duty long-haul trucks. The system will be implemented on vehicles for the European market. Production is expected to commence in late 2024.
BorgWarner’s eFan system to play a key role in cooling strategies
«We are a long-standing technology partner of this customer and this business win signals continued confidence in BorgWarner’s thermal management expertise», said Joe Fadool, President and General Manager, BorgWarner Emissions, Thermal and Turbo Systems. «Vehicle manufacturers face technically challenging emissions goals that are driving a transition from fossil fueled combustion engines toward CO2-neutral drivetrains across transportation segments. Our eFan system will perform a key role in cooling strategies for high-voltage electrified vehicles».
According to BorgWarner, which has recently completed the acquisition of German battery specialist Akasol, new generations of fully electric heavy-duty trucks will require dedicated high-voltage thermal management solutions like the eFan system to cool components such as the e-motor, battery and electronics. BorgWarner has specifically optimized its fan design for performance and efficiency using computational fluid dynamics. The HV eFan is driven by a robust e-motor, which is powered by the vehicle’s electrical system via an inverter. The power density of the motor is very high, rated at 40 kW output with compact dimensions. Similarly, it is optimized for speeds below 3000 rpm. The electric motor is liquid-cooled, and the entire package is completely encapsulated for reliable long-term operation. The system has a wide operating range from less than 650 volts up to 850 volts, ensuring compatibility with a variety of high-voltage commercial vehicle electrical systems.
