BorgWarner wins multiple component contracts in electric vehicle market

Date: 09/05/2023
Electrical engineering expert BorgWarner is trying set its foot strong in electric vehicle (EV) component market by supplying multiple key components to leading and emerging EV makers in the world. Recently it has announced winning some contracts from global electric vehicle makers for supplying, battery packs, cooling systems and motors.

BorgWarner to supply its high-voltage eFan system to a global commercial vehicle OEM for use in both the European and North American markets. Its eFan system can be used both in battery-electric vehicles (B-EVs) and fuel cell electric vehicles (FC-EVs). This cooling unit is designed for heavy-duty battery-electric trucks for reliable and efficient cooling.

eFan R10 system consists of fan, e-motor and integrated high-voltage inverter. With a operating voltage range from 600V up to 850V without derating, eFan R10 is capable of up to 10 Kw power and 40 Nm torque with an operating temperature range from minus 40 degrees Celsius 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.”

The electric motor and power electronics are liquid-cooled to achieve compactness and robustness. Fans can work efficiently at low speeds with high efficiency generate less noise during battery charging.

BorgWarner’s eFan system is modular and scalable and customisable delivering high-voltage options for wide range of powers from 5 Kw and 20 Nm torque up to 40 Kw and 160 Nm. Customers can opt for either open fans or ring fans and also can choose either external or integrated inverters with interfaces and connectors as per the customer requirements. BorgWarner gained expertise in this field by acquiring a company called Drivetek AG.

BorgWarner also wins a contract from Georgia based electric bus maker to supply battery packs where BorgWarner to sell pair of standardized ultra-high energy packs and a battery management system.

“We are eager to work together with our electric powertrain customer as we continue to cultivate and grow our relationship as partners focused on the future of electrification,” said Volker Weng, Vice President and General Manager, BorgWarner Drivetrain and Battery Systems. “This new business win with our battery technology broadens our industry reach and delivers a more efficient option for school transportation.”

BorgWarner’s battery packs are fabricated with safety and protection features such as current overcharge protection, cell-level passive propagation resistance, and electrical disconnection at the individual cell wire bonds. 98 kWh capable battery packs offer energy density of 274 Wh/liter and 177 Wh/kilogram. Production of these battery packs to start in March 2023.

BorgWarner to also supply its HVH eMotors to use in Chinese automaker’s DHT and REEV, with mass production expected to start in August 2023 in Tianjin. HVH motor takes smaller space but handles higher power by using optimized conductor-winding structure that shortens the motor length.

BorgWarner also said this motor is designed with a reduction in heavy rare earth materials, leading to a lower motor cost. The optimization of the auxiliary slot provides reduced motor NVH levels, meeting customer requirements for a quieter vehicle, offers optimal cost and increased efficiency.
