The Automotive Cells Company (ACC), a joint venture between Stellantis, Mercedes-Benz, and TotalEnergies, has reached a production milestone of five million battery cells at its facility in Douvrin, France. The current output at the site is sufficient to supply nearly 40,000 electric vehicles.
ACC plans to commission a second production block at the Douvrin plant next year, adding 12.9 GWh of capacity. This expansion will bring the total site capacity to nearly 26 GWh, with a final goal of 40 GWh across three blocks. The new capacity is intended to support Mercedes-Benz electric vehicle production.
Founded in 2020, the company employs approximately 2,500 people across its research center in Nouvelle-Aquitaine and the gigafactory in Hauts-de-France. Its NMC-chemistry batteries are currently used in eight premium electric models from the Stellantis Group, including the Peugeot E-3008 and Opel Grandland.
Despite production progress, ACC has faced challenges with high defect rates and supply bottlenecks. Stellantis recently announced temporary production pauses at its French plants in Sochaux and Rennes, partly due to limited battery supplies. ACC is currently working to stabilize production and reduce defect rates to meet demand.
