With the brand new BMW spherical cell specifically designed for the electrical structure of the NEUE KLASSE fashions, it is going to be attainable to extend the vary of the highest-range mannequin by as much as 30% (in accordance with WLTP).

The brand new BMW spherical cells include a regular diameter of 46 millimeters and two totally different heights (46xx). In comparison with the prismatic cells of the fifth BMW battery cell era, the nickel content material within the sixth-generation BMW spherical cells is greater on the cathode facet, whereas the cobalt content material is lowered. On the anode facet, the silicon content material will probably be elevated. Consequently, the cell’s volumetric vitality density will enhance by greater than 20%.


BMW is switching to a cylindrical format, 46mm in diameter with two totally different heights (46xx) for its six-generation of cells, shifting from the prismatic format of gen 5.

The battery system performs a key position within the physique construction of the NEUE KLASSE. Relying on the mannequin, it may be flexibly built-in into the set up house to save lots of house (“pack to open physique”). The cell module stage is thus eradicated.

The battery, drive practice and charging know-how within the NEUE KLASSE may even have the next voltage of 800 volts. Amongst different issues, it will optimize how vitality is provided to direct present high-power charging stations, which may obtain a a lot greater charging capability with a present of as much as 500 amperes – thus lowering the time it takes to cost the car from 10 to 80 % by as much as 30%.

The BMW Group has already awarded contracts within the two-digit billion-euro vary for manufacturing of the brand new BMW battery cells. By leveraging the great in-house experience of the corporate’s personal Battery Cell Competence Middle, the workforce from growth, manufacturing and buying has been in a position to cut back prices for the high-voltage battery considerably, as a result of new battery cell and new integration idea for battery know-how developed by BMW.

Based mostly on present market assumptions, prices may be lowered by as much as 50 %, in comparison with the present fifth era. The BMW Group has set itself the purpose of bringing manufacturing prices for fully-electric fashions right down to the identical stage as automobiles with state-of-the-art combustion-engine know-how.

To produce the battery cells wanted for the NEUE KLASSE, the BMW Group has already awarded contracts within the two-digit billion-euro vary for building of battery cell factories to CATL and EVE Power. Each companions will construct two gigafactories in China and Europe. Every of the battery cell factories can have a complete annual capability of as much as 20 GWh. Plans name for 2 extra battery cell factories to be constructed within the North American free commerce zone,
USMCA, for which the companions haven’t but been nominated.

The BMW Group is especially centered on conserving the carbon footprint and consumption of assets for manufacturing as little as attainable, beginning within the provide chain. Cell producers will use cobalt, lithium and nickel that embrace a proportion of secondary materials, i.e. uncooked supplies that aren’t newly mined, however already within the loop, in manufacturing of battery cells.

Mixed with the dedication to make use of solely inexperienced energy from renewable energies for manufacturing of battery cells, the BMW Group will cut back the carbon footprint of battery cell manufacturing by as much as 60 %, in comparison with the present era of battery cells.

Reuse of uncooked supplies will probably be one of many success elements for e-mobility sooner or later. (Earlier submit.) Round loops cut back the necessity for brand new uncooked supplies, decrease the danger of infringing environmental and social requirements within the provide chain and customarily end in considerably decrease CO2 emissions. That’s the reason the long-term purpose of the BMW Group is to make use of totally recyclable battery cells.

In China, the corporate is at the moment making a closed loop for reuse of the uncooked supplies nickel, lithium and cobalt from high-voltage batteries, thus laying the cornerstone of a ground-breaking materials cycle.

The cobalt and lithium used as uncooked supplies for the brand new era of BMW battery cells will probably be sourced from licensed mines. This implies the corporate retains full transparency over extraction strategies and, on this approach, can guarantee accountable mining. The sourcing of each uncooked supplies from licensed mines takes place both instantly by way of the BMW Group or through the battery cell producer.

The BMW Group has been actively concerned for a few years in initiatives to develop requirements for accountable uncooked materials extraction and promote compliance with environmental and social requirements for uncooked materials extraction by way of certification of mines. On this approach, the corporate can be making itself much less technologically, geographically and geopolitically depending on particular person assets and suppliers.

Growth of future BMW battery cells at in-house competence facilities. The BMW Group is continually working to additional develop vitality storage methods. For instance, its sixth-generation battery know-how additionally affords the choice of utilizing cathodes product of lithium iron phosphate (LFP) for the primary time. This implies the crucial uncooked supplies cobalt and nickel can then be prevented totally within the cathode materials.

In parallel, the BMW Group can be pushing ahead with growth of all-solid-state batteries (ASSBs). The corporate goals to have high-voltage batteries of this sort prepared for sequence introduction by the top of the last decade. The BMW Group will current a demonstrator car with this know-how on board nicely earlier than 2025.

The BMW Group has been systematically constructing experience within the discipline of battery cell know-how since 2008. Since 2019, this know-how has been concentrated on the BMW Group’s Battery Cell Competence Middle (BCCC) in Munich. The BCCC spans your entire worth chain—from analysis and growth to battery cell design to manufacturability.

To make sure improvements in battery cell know-how are put into observe shortly and effectively, the BMW Group depends on a community of round 300 companions, with cooperation between established corporations, startups and schools, amongst others.
