BMW's next-generation electric vehicles will arrive mid-decade. New batteries will offer up to 30% more range than BMW's current models as part of Neue Klasse, a new platform and family of technologies.

BMW's sixth-generation electric drive technology will be used in the Neue Klasse. The Bavarian manufacturer will switch to round cells designed for Neue Klasse-based vehicles. BMW will switch to round cells from prismatic ones.

The new battery cells will have a 46-millimeter diameter and two heights, depending on their application. The cathode will have more nickel and less cobalt.

On the anode side, silicon will be increased, resulting in a 20% higher volumetric energy density.

Neue Klasse will introduce an 800-volt electrical system to improve DC fast charging. BMW says this will cut 10 to 80% charging times by 30%.

The company promises 30 percent more range thanks to new batteries in its top-tier vehicles. The automaker estimates battery prices will drop by up to 50% compared to fifth-generation batteries.

BMW will open battery plants in Europe and China with a total annual capacity of 20 GWh to produce Neue Klasse batteries. No partners have been chosen for two more North American cell plants.
