Chinese EV brand to fit integrated drive modules

0

BorgWarner has entered into a partnership with an undisclosed New Energy Vehicle (NEV) brand from China to supply fully integrated drive modules (iDM) for a pure electric vehicle (EV) that is expected to go into mass production in 2021. This deal is with a long-term customer and represents BorgWarner’s first iDM project in China.

The iDM system integrates efficient power electronics with an advanced transmission system and drive motor featuring a high-voltage hairpin stator for good NVH levels, and full software functionality with an option for high-level control of vehicle dynamics and energy management.

The iDM product range has a scalable and modular architecture and a wide range of gear ratios and electric motor sizes, and can be integrated at either the front or rear axle, depending on the architecture and application. It is available in three different power levels, operating at 220-480V of direct current (VDC), providing up to 150Kw power and up to 3,000Nm torque, which can be further extended to 160Kw and 3,800Nm as needed for different vehicle platforms.

All components used in the iDM are part of BorgWarner’s technology portfolio, and are available as a fully integrated module or as stand-alone units. The software architecture meets current market requirements and can be adapted to common platforms like AUTOSAR, as well as allowing safety aspects such as ASIL D to be achieved. To handle the increasing volume of data exchange within modern vehicle systems, the power electronics can be used with a CAN or CAN FD bus and Flexray.
