BMW Group and Rimac Technology cooperate on innovative high-voltage battery for the BMW i7

Munich / Zagreb. The BMW Group is cooperating with
Rimac Technology (Croatia) on the new all-electric BMW i7.

The aim of the joint project is to bring the Gen6 technology
developed by BMW for an innovative high-voltage storage system for
more range and higher charging speed to the new all-electric BMW 7
Series Sedan.

The sixth generation of BMW eDrive technology (Gen6) is finding its
way into the BMW brand’s top-of-the-range all-electric model in the
form of its 4695 lithium-ion cylindrical cell. The cell is
characterised, among other things, by a 20 percent higher volumetric
energy density compared to the prismatic cells of the Gen5.

The high-voltage battery, which combines Gen6 cell technology with
the established Gen5 module design, enables the new BMW i7 to achieve
a significantly increased range.

BMW i7 customers can also charge much faster thanks to the newly
developed technology. The charging capacity is increased and the
charging time reduced accordingly.

The new BMW i7 will celebrate its world premiere on April
22^nd  at Auto China 2026 in Beijing.

“We are quickly rolling out the technologies of the Neue Klasse
across our entire model portfolio – including, of course, in our
all-electric luxury sedan. The teams of both companies have developed
a tailor-made solution for the new BMW i7,” says Dr. Thomas
Engelhardt, Senior VP Development High-Voltage Storage and Charging at
the BMW Group. “The excellent collaboration with Rimac Technology
is a good example of European innovative strength.”

The high-voltage battery is manufactured on state-of-the-art
equipment at Rimac Technology in Croatia and delivered ready for
assembly at BMW Group Plant Dingolfing, the world’s only production
facility for the BMW 7 Series.

Mate Rimac, Founder and President of Rimac Group, CEO and CTO Bugatti
Rimac says: “BMW has always been known for pushing engineering to the
highest level, which made this collaboration especially exciting for
us.
Together, we developed a high-voltage battery system that
unlocks the full potential of the new cylindrical cells in record
time, delivering significant improvements in energy, range, and
charging performance.
We are proud to now see this system being
produced at scale at our new Rimac Campus.”
