GM Will Dump The ‘Ultium’ Branding To Rethink How It Does Batteries: Exec

• GM is ready to ditch the Ultium model identify amid a broad shift in battery technique, an govt informed Bloomberg.
• GM will proceed utilizing underlying batteries and expertise platforms, but additionally incorporate LFP and nickel-rich prismatic cells.
• A brand new Battery Cell Growth Heart goals to speed up R&D.

When Common Motors launched the Ultium electrical car platform and battery system 4 years in the past, it stated that this plan—one frequent structure and household of modular batteries for all future fashions—would underpin thousands and thousands of EVs for years to return. It could additionally, in principle, imply GM might make sufficient batteries at scale for EVs to grow to be extremely worthwhile. 

However truly scaling up has been a nightmare. Now, GM needs to kill the Ultium model identify, whereas preserving the underlying tech, and alter its strategy in direction of batteries.

That element comes from an interview with former Tesla govt and GM’s present battery chief Kurt Kelty in Bloomberg. And moreover abandoning a reputation that hasn’t actually caught on, Kelty stated these strikes imply large adjustments for GM’s battery sport. 

At the moment, GM’s foremost battery associate is LG Power Resolution. Now, Kelty stated the automaker plans to include completely different battery chemistries and ranging cell shapes to tailor them to explicit fashions. GM’s present Ultium packs energy a dozen fashions, from the $35,000 Chevy Equinox EV to the $100,000 GMC Hummer EV, simply in numerous sizes.

That is prone to change for future fashions.

In accordance with Kelty, there is a “important” change coming to GM’s battery plans that will probably be revealed on the Investor Day Presentation later in the present day. Which means ditching the one-type-fits-all philosophy and tailoring battery packs to particular person fashions, one thing Tesla and BYD have been doing for years. That will embody utilizing the present pouch cells for some fashions, however probably utilizing the easier-to-assemble prismatic cells for others.

GM EVs at present are geared up with nickel-cobalt-manganese-aluminum cells made by the three way partnership with LGES. Now it plans to diversify. The automaker is in talks with Japan’s TDK Corp to supply lithium-iron-phosphate (LFP) batteries within the U.S. utilizing tech licensed from CATL. 

The next-gen Chey Bolt EV will trip on the Ultium platform, however it would use LFP batteries, as has been introduced beforehand. (Though initially, it might not use U.S.-made packs.)

LFP batteries are cheaper to supply than nickel-manganese-cobalt (NMC) cells, boast higher thermal efficiency and last more. However they’re much less power dense and therefore extra appropriate for entry degree fashions, just like the rear-wheel drive Tesla Mannequin 3 and the Commonplace Vary Ford Mustang Mach-E.

To speed up these plans, GM will conduct battery R&D on the Wallace Battery Cell Innovation Heart at GM’s campus in Warren, Michigan and on the new Battery Cell Growth Heart that will probably be formally introduced on Tuesday. The latter is anticipated to be up and working by 2027 and collectively the 2 amenities will be capable of develop new packs and get them prepared for manufacturing in 18 months.

GM can be constructing a brand new $3.5 billion battery plant in Indiana in partnership with Samsung SDI to develop nickel-rich prismatic cells.

Kelty stated all of that is meant to “considerably” scale back battery weight, drive down prices and make manufacturing much less advanced. GM final yr stated was abandoning its aim of promoting 400,000 EVs by mid-2024. Its EV gross sales have been nowhere near that, however they’re enhancing steadily. And this revised battery technique would possibly assist it unlock a brand new section of mass manufacturing whereas doubtlessly enhancing the vary and charging speeds of its EVs.

For all these challenges, together with software program points and shifting gross sales goalposts a number of instances, GM is doing comparatively nicely in electrical gross sales. It simply posted one more consecutive quarter of EV deliveries and will shut the yr as America’s no. 2 electrical automaker behind Tesla.
