BorgWarner Expands Battery Management System Program with Major OEM

On February 11, 2026, BorgWarner Inc. announced a significant expansion of its series-production battery management system (BMS) program with a global original equipment manufacturer (OEM). This expansion is set to support an increasing range of B-segment and C-segment passenger cars, as well as light commercial vehicles, specifically tailored for battery-electric vehicle (BEV) and plug-in hybrid electric vehicle (PHEV) applications. Production for these vehicles is slated to commence in 2029.

BorgWarner has been supplying its advanced BMS to this particular customer since 2023, showcasing a longstanding relationship and trust in BorgWarner’s capabilities. Dr. Stefan Demmerle, Vice President and President of BorgWarner PowerDrive Systems, expressed his enthusiasm for the expanded program, noting, "We're pleased to expand our series-production battery management program, highlighting our customer's confidence in our production-proven design that's already performing in real-world vehicle applications."

This expansion comes at a time when the automotive industry is undergoing a significant transformation towards electrification. BorgWarner's BMS is crucial in meeting the growing demand for efficient, safe, and durable electric vehicles.

BorgWarner's BMS is designed as a modular system, consisting of a central battery monitoring unit (BMU) and various cell monitoring units (CMUs). This architecture enables comprehensive monitoring of critical battery metrics, such as charge levels, battery health, temperatures, and cell voltages. The system also performs passive cell balancing, which optimizes performance and ensures long-term durability.

The BMS supports fast direct current (DC) charging communication and incorporates built-in controls and diagnostics that are essential for meeting stringent safety requirements, including Automotive Safety Integrity Level D (ASIL D) functional safety goals. This focus on safety is particularly pertinent as the automotive industry continues to embrace electrified platforms.

The scalable nature of the architecture allows for configuration across a broad range of BEV and PHEV battery pack designs, making it adaptable for various applications operating up to 800 volts. The compact module-level units facilitate flexible packaging options, which is crucial as vehicle designs evolve.

BorgWarner's extensive experience in global automotive electronics underpins this expanded program. The BMS design has been validated in series production, enabling customers to efficiently scale their electrified vehicle portfolios while capitalizing on established functionalities and a solid supply chain.

BorgWarner's expansion of its battery management system program marks a pivotal development in the realm of electric mobility. As the automotive industry transitions towards a more electrified future, BorgWarner's commitment to innovation and quality positions it as a key player in the market. This initiative not only enhances their competitive edge but also contributes significantly to the global movement towards sustainable transportation solutions.

In summary, BorgWarner is not just adapting to the changing landscape; it is actively shaping the future of electric vehicles through advanced technology and strategic partnerships.
