GM Set To Stroll Away From Ultium Label Amid Battery Technique Shake-Up – CleanTechnica – TechnoNews

In 2020, Common Motors held a splashy week-long ceremony at its Technical Heart in Warren, Michigan, to introduce its new Ultium battery and EV platform applied sciences. CEO Mary Barra enthused that Ultium was “a multi-brand, multi-segment EV strategy with economies of scale that rival our full size truck business with much less complexity and even more flexibility.”

Ultium, after all, is a made-up phrase created by GM’s advertising division. It was new, recent, and urged the longer term. Nonetheless, it meant nothing to anybody outdoors the corporate. That left loads of room for GM to fiddle with the content material of the thought with out altering the title.

In keeping with Wikipedia, Ultium refers to a complete electrical car drive system consisting of battery packs, drive motors, and a wi-fi battery administration system, developed in partnership with Analog Gadgets. The wi-fi BMS is claimed to require 90% much less wiring, which reduces battery pack quantity by 15% and helps decrease the price of battery packs. Ultium battery cells function massive format pouch cells that use nickel cobalt manganese aluminum (NCMA) chemistry. They had been initially scheduled to be manufactured by Ultium Cells LLC, a three way partnership between GM and LG Vitality Resolution. GM appears to not have gotten the memo about cylindrical battery cells that use LFP chemistry till a lot later.

In China, Ultium-branded battery cells are cylindrical and use nickel manganese cobalt (NMC) chemistry provided by CATL. In April, GM began altering course for its Ultium battery expertise when it introduced a three way partnership with Samsung SDI for its subsequent US battery manufacturing unit that can manufacture prismatic and cylindrical Ultium battery cells. The second era Chevrolet Bolt will use Ultium cells with lithium iron phosphate chemistry.

GM Could Be Prepared To Transfer On From Ultium

In keeping with Bloomberg, the title Ultium might quickly disappear at GM. It has employed Kurt Kelty, who previously labored at Tesla, to be answerable for its electrical car battery program. On the corporate’s investor day on October 8, 2024, he’s anticipated to announce that GM is taking a brand new path ahead for its electrical automobiles, one which will see the demise of the Ultium model. The brand new route will see using completely different chemistries, quite a lot of shapes for battery cells, and other ways to package deal them for its future electrical automobiles. Kelty may even clarify how the brand new initiative will lower the price of batteries.

Kelty says the strategic rethink isn’t a revolution a lot as a “significant” change made vital by battery manufacturing issues which have constrained gross sales and an absence of title recognition with shoppers for the Ultium model. GM’s battery meeting vegetation have had persistent issues with the automation that packs battery cells into modules, which delayed the launch of the Hummer EV and saved different automobiles from stepping into mass manufacturing. Its EV meeting strains have solely lately began shifting at scale.

The Ultium model, initially meant to be the auto trade’s model of “Intel Inside,” by no means turned a promoting level for shoppers, individuals accustomed to the matter advised Bloomberg. It was strictly a advertising ploy that meant little to clients as a result of GM gave them little particular details about what it stood for. It’s arduous to determine a brand new model that doesn’t correlate with what clients know, or suppose they know.

Constructing Ultium batteries to date has been problematic, making it tough for GM to promote greater than 70,000 EVs to date this yr, with gross sales solely lately beginning to rise. GM had hoped to have the ability to construct 400,000 EVs by the center of 2024 and have manufacturing in place to provide 1 million of them by the tip of 2025. Going ahead, GM’s battery pack — which at present varieties the premise for a dozen EVs starting from the small Chevrolet Equinox to the 9,000 pound electrical Hummer — will now not be “one type fits all,” in keeping with Kelty.

GM Emphasizes Distinction From Different Automobile Corporations

Along with Kelty’s presentation on batteries, CEO Mary Barra, GM president Mark Reuss, CFO Paul Jacobson, and others plan to talk at Tuesday’s occasion in a coordinated effort to steer buyers that GM is in a distinct place than different auto firms. They may say the corporate’s core enterprise is more healthy and its future expertise bets, equivalent to EVs, self-driving automobiles, and software program associated providers, are beginning to achieve traction. “The market wants to hear that the EV strategy will be profitable immediately and what they will do about their problems in China,” David Whiston, a Morningstar Inc. analyst, mentioned.

In 2021, Barra pushed the Ultium story arduous at an Investor Day occasion. Morgan Stanley auto analyst Adam Jonas even urged GM ditch its 100-year-old title and name your entire firm Ultium. Barra claimed the corporate might double income to $280 billion by 2030 partly as a result of the Ultium battery pack might give rise to all kinds of EVs rapidly. She mentioned GM might increase its lineup sooner than market chief Tesla and achieve a much bigger slice in a quick rising sector of the auto enterprise. In actual fact, GM has simply introduced that EV gross sales had been fairly robust within the first half of 2024 and getting stronger.

The Ultium technique resulted in heavy and costly automobiles which have lengthy vary, however aren’t individually optimized. Hyundai and Volkswagen have a method just like GM’s, however Tesla and China’s BYD tailor battery packs to every mannequin. Kelty has been engaged on a future plan that applies a extra personalized strategy to every car, whereas decreasing prices and weight. “We’ve got so many different products in different areas, that we need to find an optimal solution for each one,” he mentioned. “It’s not necessarily the same form factor or same chemistry.”

Welcoming LFP Batteries To The GM Household

Kelty mentioned, some future automobiles will nonetheless have pouch cells and modular building just like Ultium, whereas others might get their very own bespoke, devoted battery pack like Tesla makes use of. GM might follow the floppy pouch cells that its EVs use now. Others might go to steel-encased prismatic cells that Kelty mentioned will be simpler to package deal.

The corporate has been in discussions with Japan’s TDK to make batteries in a US manufacturing unit that use lithium iron phosphate expertise licensed from CATL. When the second era Chevy Bolt goes into manufacturing subsequent yr, it can use LFP batteries, however they won’t come from TDK. It would take some time for that partnership to bear fruit. Who will provide these batteries is unknown at the moment, however it’s a certain wager they are going to adjust to the present US Treasury guidelines in order that these automobiles might be eligible for the total federal EV tax incentive.

If GM can ship, Kelty could have a narrative that EV-wary buyers need to hear. “Our next-gen battery packs will have significantly less other parts, significantly less weight, significantly less cost,” he mentioned. “All that is for our next generation that is being developed right now. We’re moving fast.”

The Takeaway

GM has definitely had its struggles with electrical automobiles, starting with the battery fires related to the primary era Chevy Bolt. Maybe these points are a part of the rationale Honda determined to stroll away from its partnership with GM to construct the brand new Honda Prologue and an Acura mannequin on the GM manufacturing unit in Spring Hill, Tennessee. Each of these automobiles are primarily based on the so-called Ultium platform.

Ever for the reason that earliest days off the EV revolution, producers have been entranced by the pliability that battery energy brings to automotive design. Early leaders like Faraday Future bragged about creating modular platforms that could possibly be diversified to fulfill buyer wants and tastes. The EV of the longer term could possibly be longer, shorter, wider, narrower, greater, or decrease as buyer tastes dictated and would all be primarily based on one extremely versatile chassis, identified within the trade as a skateboard or platform. Volkswagen has taken this route with its MEB platform and Hyundai/Kia is doing one thing comparable with it E-GMP design.

Errors are the most effective lecturers, nevertheless. GM has made just a few, however now thinks it has its home so as and is able to grow to be a excessive quantity producer of electrical automobiles. Definitely CleanTechnica has had loads of damaging issues to say about GM over time. We might be solely too pleased to be confirmed improper.
