How BMW will supply cheaper, longer-range EVs from 2025

BMW has introduced it is going to be utilizing newly-developed cylindrical battery cells from Chinese language battery giants CATL and EVE Power in its upcoming Neue Klasse autos from 2025.

This confirms previous reports from earlier this 12 months noting that CATL signed an settlement with BMW to be nominated because the provider of the brand new cylindrical cells.

BMW has already given CATL and EVE Power contracts which can be “within the two-digit billion euro vary”, or no less than $A15 billion, to supply the brand new round battery cells.

Utilizing its in-house Battery Cell Competence Centre, BMW mentioned it has been capable of “considerably scale back prices for the high-voltage battery”, thanks partly to the brand new cylindrical battery cell.

BMW claims these new battery cells will scale back manufacturing prices by as much as 50 per cent in comparison with its present, fifth-generation prismatic battery cells.

BMW additionally mentioned it’s focusing on manufacturing value parity between battery-electric autos (BEVs) and internal-combustion engine (ICE) autos, however didn’t give a timeline of when to anticipate this.

Along with decreased manufacturing prices, BMW mentioned it’s attainable to “considerably enhance the vary” of a flagship Neue Klasse mannequin by as much as 30 per cent, in line with WLTP testing.

The spherical battery cells will even be 20 per cent extra power dense in comparison with present, fifth-generation BMW battery cells.

The German carmaker has mentioned these new spherical battery cells have been specifically designed for Neue Klasse fashions, and have “essentially refined” cell format and cell chemistry.

There’s additionally the choice of lithium iron phosphate (LFP) battery chemistry too, which is finest identified for being cheaper to supply however much less power dense.

The high-voltage parts in Neue Klasse autos may have a voltage of 800V, in comparison with the present 400V within the iX, in addition to an amperage of 500 amps.

BMW claims it will scale back 10 to 80 per cent charging time by as much as 30 per cent.

These new BMW spherical battery cells will measure in at 46mm in diameter, however are available in two totally different heights. BMW hasn’t disclosed what these heights are but.

When the spherical batteries come to market they are going to compete squarely in opposition to Tesla’s 4680 cylindrical lithium-ion battery cells, that are going to be produced by Panasonic and measure 46mm and 80mm lengthy.

BMW mentioned it’s going to start manufacturing “near-standard manufacturing of samples” in late 2022.

These new cylindrical battery cells might be produced in two gigafactories in China and Europe, with plans for 2 extra in North America.

Every of those battery cell factories may have a complete annual capability of as much as 20GWh.

BMW says it goals to scale back the carbon footprint of battery manufacturing by as much as 60 per cent, in comparison with the present era of battery cells.

BMW’s new collection of EVs primarily based on the Neue Klasse architecture is set to debut in 2025 on a 3 Series-sized vehicle.

It’s nonetheless unknown what this primary Neue Klasse automobile might be often called. It might put on the i3 badge, which is at present used on a 3 Series EV for China and was beforehand used on the quirky hatch.

The brand new 3 Collection-sized EV might be constructed at a brand new manufacturing unit being constructed in Debrecen, Hungary.

Seeking to the long run, BMW is “pushing ahead” with the event of all-solid-state batteries and goals to have high-voltage batteries of this sort prepared for collection introduction by the tip of this decade.

The German carmaker additionally plans to disclose a demonstrator automobile fitted with this solid-state battery expertise “nicely earlier than 2025”.

Not like some other automakers, BMW has but to make any bulletins about when it’s going to finish growth and manufacturing of ICE autos.

The carmarker’s newest plan requires it to supply a complete of two million all-electric automobiles by 2025. By 2030, the corporate expects half of its annual world gross sales to be EVs.
