BorgWarner’s battery management system (BMS) has been selected for an expanded series-production program with a global original equipment manufacturer. 
The company has supplied the BMS to the customer since 2023. The expanded program will support additional B-segment and C-segment passenger vehicles, along with light commercial vehicles, for battery-electric (BEV) and plug-in hybrid (PHEV) platforms beginning in 2029.
The BMS features a modular architecture consisting of a central battery monitoring unit (BMU) connected to cell monitoring units (CMUs) located at individual battery modules. The system monitors state of charge, state of health, and temperature, measures cell voltages, and performs passive cell balancing to support battery performance and durability.
The platform supports fast direct current (DC) charging communication and incorporates functional safety measures aligned with Automotive Safety Integrity Level D (ASIL D) requirements. The architecture is scalable across a range of BEV and PHEV battery pack configurations and is suitable for applications operating at voltages up to 800 V.
The module-level design enables flexible battery pack integration across multiple vehicle segments. The electronics platform is designed to accommodate future feature updates as vehicle electrification requirements evolve.
