BMW plans to begin series production of high-voltage batteries for the all-electric BMW iX5 at its new Woodruff plant in South Carolina in December 2026. According to the company, test and pre-series batteries are already being produced at the facility. The batteries will then be shipped to the nearby Spartanburg vehicle plant, where the iX5 will be assembled.
The Woodruff plant is part of BMW’s global “Local for Local” production strategy, under which batteries are assembled close to the company’s vehicle manufacturing plants. In addition to Woodruff, BMW has established or is establishing similar battery assembly sites in Germany, China, Mexico, and Hungary.
AI and digital planning intended to improve battery assembly
According to BMW, the Woodruff plant uses AI-supported production processes, digital twins, and virtual reality applications. More than 300 employees and 250 robots are expected to support the assembly of high-voltage batteries. The company says all production steps are continuously monitored and documented in real time. AI assistants are intended to analyze the resulting data and support manufacturing operations.
Gen6 battery with 800-volt architecture for the BMW iX5
The batteries are based on BMW’s sixth-generation high-voltage battery technology. Cylindrical battery cells are integrated directly into the battery pack using the company’s Cell-to-Pack design.
The battery-electric BMW iX5 will feature BMW’s sixth-generation eDrive technology with an 800-volt architecture. According to the company, the high-voltage battery provides a usable energy capacity of 144 kWh in the U.S. and 141 kWh in Europe, making it the largest battery ever offered in a fully electric BMW model.
