For the sixth technology of BMW eDrive technologies utilised in the NEUE KLASSE, the firm has basically refined the cell structure and mobile chemistry. With the new BMW round cell specifically intended for the electric powered architecture of the NEUE KLASSE designs, it will be achievable to considerably maximize the variety of the best-vary model by up to 30 per cent (according to WLTP).

The new BMW round cells arrive with a typical diameter of 46 millimetres and two various heights. In contrast to the prismatic cells of the fifth BMW battery cell era, the nickel material in the sixth-technology BMW round cells is higher on the cathode side, although the cobalt articles is reduced. On the anode facet, the silicon written content will be improved. As a consequence, the cell’s volumetric electricity density will make improvements to by additional than 20 percent.

The battery process performs a important purpose in the human body composition of the NEUE KLASSE. Based on the model, it can be flexibly integrated into the set up space to preserve house (“pack to open up body”). The cell module degree is so eradicated.

The battery, travel coach and charging engineering in the NEUE KLASSE will also have a larger voltage of 800 volts. Among the other items, this will optimise how vitality is equipped to immediate recent superior-electrical power charging stations, which can accomplish a considerably bigger charging capacity with a existing of up to 500 amperes – as a result lowering the time it usually takes to cost the car or truck from 10 to 80 per cent by up to 30 per cent.

Battery mobile factories in China, Europe and USMCA – every single with overall potential of up to 20 GWh for every 12 months

To source the battery cells wanted for the NEUE KLASSE, the BMW Group has previously awarded contracts in the two-digit billion-euro range for design of battery cell factories to CATL and EVE Strength. Equally partners will create two gigafactories in China and Europe. Each of the battery mobile factories will have a total yearly potential of up to 20 GWh. Strategies connect with for two far more battery cell factories to be crafted in the North American absolutely free trade zone,
USMCA, for which the partners have not nonetheless been nominated.

The 3 locations in which the battery cell factories will be designed will also gain economically from the generation of new source chains, new networks for subcontractors and new careers.

CO2-decreased production employing green power and secondary material

The BMW Team is specially centered on retaining the carbon footprint and usage of methods for manufacturing as reduced as doable, starting off in the supply chain. Mobile manufacturers will use cobalt, lithium and nickel that include things like a proportion of secondary materials, i.e. uncooked products that are not newly mined, but already in the loop, in manufacturing of battery cells. Merged with the commitment to use only environmentally friendly electric power from renewable energies for generation of battery cells, the BMW Team will reduce the carbon footprint of battery cell manufacturing by up to 60 %, when compared to the latest technology of battery cells.

Reuse of uncooked resources will be 1 of the achievements components for e-mobility in the long run. Circular loops lower the will need for new raw elements, lower the danger of infringing environmental and social criteria in the source chain and commonly consequence in noticeably lessen CO2 emissions. That is why the very long-time period objective of the BMW Group is to use thoroughly recyclable battery cells. In China, the company is at the moment creating a closed loop for reuse of the uncooked products nickel, lithium and cobalt from superior-voltage batteries, therefore laying the cornerstone of a ground-breaking materials cycle.

The cobalt and lithium applied as raw elements for the new generation of BMW battery cells will be sourced from accredited mines.
