- BorgWarner will expand its Battery Management System supply for additional BEV and PHEV models starting in 2029.
- The modular architecture with BMU and CMUs enhances flexibility, safety, and battery performance optimization.
On February 16, BorgWarner announced the expansion of its series-production Battery Management System supply to a global original equipment manufacturer. The extended program builds on an existing partnership that began in 2023 and will support additional B-segment and C-segment Passenger Cars as well as light Commercial Vehicles. The expanded Battery Management System application will cover battery-electric vehicle and plug-in hybrid electric vehicle platforms starting in 2029, reinforcing the company?s position in Electrification and advanced battery control technologies.
Expanded Battery Management System Program for 2029
The expanded Battery Management System agreement enables BorgWarner to support a broader range of electrified models across multiple vehicle segments. Beginning in 2029, the system will be integrated into new battery-electric vehicle and plug-in hybrid electric vehicle platforms, including B-segment and C-segment Passenger Cars and light Commercial Vehicles. This long-term supply arrangement reflects continued collaboration with the original equipment manufacturer and highlights growing demand for scalable battery solutions.
Supporting BEV and PHEV Applications
The Battery Management System is designed to meet the performance and safety requirements of both battery-electric vehicle and plug-in hybrid electric vehicle architectures. By offering compatibility across different electrified powertrain configurations, BorgWarner strengthens its portfolio within Components & Subsystems while addressing evolving OEM platform strategies.
Modular Architecture with Centralized Control
BorgWarner?s Battery Management System features a modular architecture consisting of a central battery monitoring unit connected to cell monitoring units installed in each battery module. This configuration allows precise and continuous supervision of key battery parameters across the entire pack.
Battery Monitoring Unit and Cell Monitoring Units
The central battery monitoring unit coordinates data from distributed cell monitoring units, enabling accurate measurement of charge levels, battery health, and operating temperatures. The Battery Management System actively controls cell voltages to optimize performance, improve efficiency, and extend overall battery life while maintaining functional safety standards.
Design Flexibility and Safety Advantages
As a standalone supplier, BorgWarner does not rely on specific battery manufacturers, giving original equipment manufacturers increased sourcing flexibility. The modular Battery Management System supports high expandability, allowing adaptation to different battery sizes and vehicle platforms. This approach enhances vehicle design flexibility, improves integration efficiency, and strengthens safety features through precise monitoring and control capabilities.
Through this expanded supply program, BorgWarner reinforces its strategic role in Electrification by delivering a scalable Battery Management System solution tailored for next-generation Passenger Cars and Commercial Vehicles.
