BorgWarner supplies integrated drive module to Chinese EV maker

BorgWarner, a global leader in delivering innovative and sustainable mobility solutions based in Auburn Hills, Michigan, U.S.A., has begun supplying its advanced integrated drive module (iDM220) to Chinese automaker Li Auto’s new energy vehicles (NEVs). This marks BorgWarner’s first iDM business in China, a significant milestone in the electric vehicle industry.

The iDM220, currently installed in two of Li Auto’s model-lines, including the L8 and L9 range-extended electric vehicles, is a highly-integrated electric drive module operating at 400V. It is capable of providing over 200 kW of maximum power and an estimated 4500 Nm of peak torque. The module offers high efficiency, smooth and quiet operation, and exceptional performance.

An integrated drive module (iDM) in an electric vehicle (EV) is a comprehensive system that combines multiple key components of the electric drivetrain into a single unit. Specifically, the iDM integrates an electric motor with a compact, hairpin-wound stator, an integrated off-axis gearbox, and a 400V silicon-based inverter. This integration significantly reduces the weight and size of the entire system, making it a more efficient solution for new energy vehicles. In essence, an integrated drive module is a holistic solution designed to streamline the electric drivetrain, making EVs more efficient, compact, and potentially more affordable.

“We are delighted to kick-off our first iDM production in China and expand our partnership with Li Auto,” said Dr. Stefan Demmerle, president and general manager, BorgWarner PowerDrive Systems. “BorgWarner’s iDM220 is designed to meet the needs of diverse installation adaptations by providing a scalable, modular architecture. We look forward to assisting Li Auto in unleashing their future sustainability capabilities by contributing industry-leading electrification solutions.”

The iDM is produced in the BorgWarner Wuhan, China plant using inverters from the BorgWarner Suzhou, China plant. Additionally, BorgWarner’s Tianjin, China plant indirectly supplies the traction motor and generator motor for the front axle on Li Auto’s L7, L8, and L9 models.
