BorgWarner has announced that it will be supplying Li Auto, its advanced integrated drive module (iDM220), to the company’s new energy vehicles. This is BorgWarner’s first iDM business in China and is currently installed in two of Li Auto’s model lines, including the L8 and L9 range-extended electric vehicle (REEV).
The iDM is produced in the BorgWarner Wuhan plant using inverters from its Suzhou plant. In addition, its Tianjin plant indirectly supplies the traction motor and generator motor for the front axle on Li Auto’s L7, L8 and L9.
The iDM220 is a highly-integrated electric drive module operating at 400V, providing over 200 kW of maximum power and an estimated 4,500 Nm of peak torque. The module offers efficient, smooth and quiet operation.
The iDM incorporates an electric motor with a compact, hairpin-wound stator with an outer diameter of 220 mm, an integrated off-axis gearbox, and a 400V silicon-based inverter, significantly reducing the weight and size of the entire system.
All subsystems used in the iDM are part of the company's technology portfolio and are available either as fully integrated module or as stand-alone solutions for new energy vehicles.
Dr Stefan Demmerle, President and General Manager, BorgWarner PowerDrive Systems, noted that the company’s iDM220 is designed to meet the needs of diverse installation adaptations by providing a scalable, modular architecture and is expected to power smart, efficient and reliable mobility solutions for the customers.
