BMW Opens US Battery Plant in Woodruff to Power the American-Built iX5
Based on BMW Group’s own announcement of November 13, 2026.
BMW has started building batteries in the United States. The company today officially opened Plant Woodruff in South Carolina, where series production of its sixth-generation (Gen6) high-voltage batteries has begun — 15 miles from the Spartanburg vehicle plant they are made for. The first car to receive them is the new BMW iX5, which will be the first fully electric BMW ever assembled in America.
What the Woodruff plant makes
One product, one destination: Gen6 battery assemblies for Spartanburg’s electric models.
The batteries assembled at Woodruff go into the electric BMWs built at Spartanburg, starting with the iX5. BMW board member Raymond Wittmann said the plant will assemble at least six fully electric models by 2030, and called Woodruff’s start much more than the launch of a new site — it lays the foundation for the first series production of fully electric BMW vehicles in the United States. BMW calls the arrangement “Local for Local”: the battery plant and the vehicle plant sit in the same state, 15 miles (25 km) apart.
The battery itself: what Gen6 promises
The figures BMW quotes for its Gen6 cells are generational, not incremental.
Against its Gen5 cells, BMW claims more than 20% higher energy density, charging times reduced by up to 30% and range 30% higher — even more in certain models — with CO2e emissions reduced by around 28% per watt-hour. The cells also carry a high share of recycled — secondary — cobalt, nickel and lithium. These are the same Gen6 numbers behind BMW’s Neue Klasse models now reaching Europe; the iX5 takes the technology into an American-built car. For context, the electric BMWs on sale in the US today still run on the previous generation — our BMW i4 battery guide covers what that looks like in a car you can buy now.
The fourth plant in a three-continent network
Woodruff completes the map: Gen6 battery assembly now runs in Europe, Asia and North America.
Woodruff is the fourth Gen6 site to start series production, after Debrecen in Hungary, Irlbach-Straßkirchen in Germany and Shenyang in China, with a fifth site completing the network. Inside the plant, BMW says production uses AI-supported processes, digital twins and virtual-reality training, under a consistent zero-defect approach. More than 300 employees work at the site, alongside around 250 robots.
Bottom line
A plant opening does not put a new car in a showroom. The iX5 is still to come, and BMW has not yet published the figures that will matter most — its battery size, range and charging speed. But the direction of travel is now fixed in concrete: the batteries for America’s electric BMWs will be made in South Carolina, not shipped across an ocean. For anyone tracking where EV batteries are actually built, that is the part of this story worth watching.
