Large Round Battery Cells like Tesla, BMW Confirms New EV Strategy webfi network



BMW’s new battery strategy is similar to that of Tesla. There were numerous rumors about this before, and now BMW has confirmed them and added further information: The company’s next generation of electric cars, known as the New Class, will use round battery cells, at least half of them in a format known from Tesla.

Thanks to higher density and new technology, the 46xx batteries should cost 50 percent less than those previously used. However, BMW does not want to produce them itself, but with partners. With CATL and Eve Energy, these have already been found for four of the six planned factories.

Optimized BMW chemistry half in Tesla format.

The three companies involved announced this in part on Friday. In its announcement , BMW writes of a newly developed sixth generation of its own lithium-ion cells as a “huge technological leap”. The energy density should increase by more than 20 percent, the charging speed by 30 percent and the range by 30 percent, probably in comparison to the current BMW electric cars i4 and iX. New integration concepts are also expected to reduce costs by up to 50 percent.

The cell format and chemistry have been fundamentally optimized and designed specifically for the new class from 2025, BMW writes of itself September 2020 as the basis for its own production. Instead of always 80 millimeters as with Tesla, BMW wants to use two different heights, but does not name them specifically.

Inside, the proportion of nickel in the cathode should be higher and that of cobalt lower and the anode should contain more silicon, the German company has now announced. The new electric cars coming from 2025 should charge with 800 volts and up to 500 amperes, i.e. 400 kilowatts. At the more economical end of its range, BMW, like Tesla before it and then more and more other Western manufacturers , also wants to use LFP chemistry for its new batteries, which does not require nickel and cobalt.

    400kW in a country that had switched off its non coal power stations and is facing a cold winter with no gas and possibly huge power shortages. A well they also sell e-bikes…

    BMW's new strategy: COPY TESLA. This means current buyers of BMW's expensive but mediocre ev are suckers who paid for their failed experiments.
