The BMW Group partnered with Rimac Technology to develop the new, all-electric BMW i7. At the heart of the vehicle is a newly developed high-voltage battery based on the sixth generation of BMW eDrive technology. Their goal is to increase range and charging speed.
BMW’s Gen6 battery technology uses cylindrical 4695 lithium-ion cells. According to the company, this cell design achieves a volumetric energy density that is approximately 20 percent higher than that of the prismatic cells of the previous generation. The high-voltage battery combines this new cell technology with the familiar module structure of the Gen5 architecture. This combination is intended to increase the range of the BMW i7. At the same time, the goal is to increase charging power to shorten charging times.
Production at Rimac
In addition to collaborating on the development of the battery pack, Rimac Technology will also handle its production. All battery manufacturing takes place in Croatia. The assembled packs are then transported to the BMW plant in Dingolfing for final assembly. This plant serves as the central production site for the BMW 7 Series. The new BMW i7 is scheduled to be unveiled for the first time on April 22, 2026, at “Auto China 2026.”
