BMW’s future vary of Neue Klasse electrical automobiles will characteristic superior new lithium-ion battery cells that can increase vary by as a lot as 30 per cent.
The automaker’s Gen 6 battery is at present below growth on the BMW Group Battery Cell Centre of Excellence in Munich, Germany and adopts a cylindrical form. The form of the cell will enable BMW to ditch the present prismatic cells it at present configures in modules which might be bolted collectively to create a pack and as an alternative, enable for a brand new cell-to-pack design to be adopted.
The brand new design will enable the battery pack to be mounted straight into the car’s body. This received’t simply enhance chassis stiffness and journey high quality however will contribute to a price saving of fifty per cent for the battery pack. Charging the battery from 10 to 80 per cent may also take 30 per cent much less time than BMW’s present EV fashions.

Auto Information notes that the brand new cell makes use of extra nickel and silicon whereas utilizing much less cobalt. Certainly, the cathode within the battery cell has 50 per cent much less cobalt whereas the anode has 20 per cent much less graphite. The German automotive producer may also use recycled cobalt, nickel and lithium and produce the cells utilizing renewable power.
“Power density is way greater than earlier than,” BMW’s Simon Erhard mentioned. “You’ll be able to put extra cells into the battery pack. With Gen 6, we’re integrating cylindrical battery cells straight into the car. It’s now a part of the physique. The principle problem is to attain the precise compromise between stiffness and adaptability. Probably the most built-in [design] can be the place the car flooring is the higher a part of the battery pack.”
BMW plans to construct various electrical crossover fashions based mostly on its Neue Klasse platform at its South Carolina manufacturing unit from mid-decade. Dealing with manufacturing of the Gen 6 battery cells can be Envision AESC, working out of a manufacturing unit in South Carolina able to producing sufficient batteries to energy 300,000 EVs yearly.
