BorgWarner has secured a contract from a premium European automaker to supply an 800-volt Integrated Drive Module (iDM) for a Range Extended Electric Vehicle (REEV). Mass production is scheduled to begin in 2029.
Highlights
- BorgWarner will supply an 800V Integrated Drive Module to a premium European OEM for a range extended electric vehicle platform launching in 2029.
- The iDM uses a single electric machine for both generator and propulsion functions, consolidating two major REEV components into one unit.
- The system features next-generation Viper power switches and dual-side cooled power module technology for high-voltage, high-current operation.
- An all-wheel-drive mode is available when additional traction is required.
Single-Machine Design Combines Generator and Drive
The iDM integrates generator and drive functionality into a single electric machine. This approach consolidates two core REEV functions into one product, reducing complexity in the vehicle architecture.
The system pairs with an inverter, two clutches, a dual-mass flywheel, and the customer’s internal combustion engine. Beyond energy-efficient generator operation, the module supports an all-wheel-drive mode when needed.
Viper Power Switches and Advanced Thermal Management
The inverter within the iDM incorporates BorgWarner’s next-generation Viper power switches and dual-side cooled power module technology. The platform is designed for high-performance electric drive applications and targets strong electrical performance and thermal management under demanding high-voltage and high-current conditions.
Global Collaboration Led by China Team
Dr. Stefan Demmerle, Vice President of BorgWarner Inc. and President and General Manager of PowerDrive Systems, noted that the China-based team led development in collaboration with a global engineering group. The result is a solution that balances performance, efficiency, and packaging for next-generation range extended vehicles.
