GM's Ultium propulsion strategy for EVs: 400 miles or more, up to 1,000 hp
https://www.greencarreports.com/news/11 ... o-1-000-hp

General Motors provided Wednesday the most comprehensive picture yet of how its “all-electric future” will take form—quickly, efficiently, and profitably, as the company emphasized. . . .

. . . the company previewed 11 fully electric vehicles in different stages of development . . . it distilled the philosophy behind its so-called BEV3 architecture to a very simple common thread: One cell family, one motor family, endless possibilities.

The so-called Ultium battery packs will range from 50 to 200 kilowatt-hours, with a driving range of “up to 400 miles or more,” while motor power (via one, two, or three motors) will add up to a total of 235 hp to 1,000 hp per vehicle.

Through GM’s $2.3 billion joint venture with LG Chem, at an upcoming facility set to break ground in Lordstown, Ohio, in April, the company will have a dedicated cell capacity of more than 30 gwh per year, with room to expand. Groundbreaking for the new facility will be this spring.

GM’s cell modules will have a built-in battery management system that allows the automaker to upgrade cells down the line more easily, and the large-format cells cut out 80 percent of the wiring versus using smaller cells.

Depending on the vehicle, GM can stack its large-format pouch modules horizontally or vertically, with a total of 19 different battery and drive unit configurations. That will be a dramatic reduction in complexity compared to the 555 different internal-combustion powertrain combinations the company has today.

The new architecture can support front-, all-, or rear-wheel drive, using versions of the same motor family mounted in front or in back.

GM has what amounts to a single component set that spans cars, crossovers and trucks, with a platform shared among the cars and crossovers. One key difference between GM’s strategy and those of some other automakers is that it’s not a skateboard—meaning that the components come together in a way that does not suggest building “rollers” that can then fit propulsion systems. That leaves the option open for most or all of the cars and crossovers to share some common body or chassis components while trucks might be body-on-frame.

Trucks also deviate from the format in offering the possibility of double-stacking battery packs, which allows GM to connect them to enable 800-volt charging and 350-kw DC fast-charging capability. Ultimately that will enable charging rates of up to 100 miles in 10 minutes for either the 400- or 800-volt versions. . . .

Prior to both of these models [GRA: Hummer, Cadillac Lyriq], a refreshed version of the Bolt EV will launch late this year, followed by the Bolt EUV—a version built on a wheelbase 3 inches longer but carrying over the existing battery pack and front-wheel drive. The EUV will be the first of many vehicles outside of Cadillac to offer its SuperCruise driver-assist system.

Prior to the introduction of the EUV, GM is anticipating that Bolt EV sales will double year over year, to 50,000, with 30,000 for the U.S. . . .

Seeing as how the demand is for AWD CUVs, why on earth would GM make the same mistake that Ford (C-Max, Escape PHEV) and Hyundai/Kia have made and not offer the EUV with AWD? This is dumb.

The refreshed bolt sounds pretty good depending on price. New seats and interior and adaptive cruise and new infotainment screen and software, plus a few other things.

2021 bolt range will be the same but that was expected since it increased for 2020.
A downside of that is that charging speeds still top out around 50 kw.

The EUV, besides not having AWD, gets the same pack so that means the EUVs range will be shorter than the bolt.

IEVS:
Nikola To Merge With VectoIQ And Be Listed On NASDAQ
https://insideevs.com/news/402148/nikola-merge-vectoiq/

Nikola Corporation, which develops electric and hydrogen fuel cell vehicles, announced a surprising definitive agreement to merge with VectoIQ Acquisition Corp., described as "a publicly-traded special purpose acquisition company".

Once completed, the combined $3.3 billion company will be named Nikola Corporation and is expected to remain NASDAQ-listed under the new ticker symbol “NKLA” (VectoIQ was already listed on NASDAQ as VTIQ). The area of interest will remain similar: "the development of next generation smart transportation".

The deal includes also a $525 million private placement of common stock so the new entity will have a surplus of cash. . . .

Nikola Corporation boasts that so far it collected more than 14,000 pre-orders for its trucks, which represents more than $10 billion in potential revenue and two-and-a-half years of production.

The company hopes to generate first revenues from selling all-electric vehicles by 2021, and from selling hydrogen fuel cell vehicles in 2023. . . .

2019 Bolt DC FC rate tops out at 55 kW. I've hit it. IIRC, it's the same on 2020 but the tapers are more gradual instead of the weird sharp drops on 2017 to 2019.

If the DC FC rate isn't increased for 2021, that's unfortunate.

What technical reason would keep them from raising it to something like 100.

I was wondering that too. It could be their cell or pack design or max cooling, or it could be they are saving that as a feature for higher end models they are listing. One would think that with this new platform they were going on about that at 60+ kWh they would be able to hit more than 55 kW

Yah. We just came through Harris Ranch and noticed that there were 8 Chademo/CCS stations being installed there. Interestingly enough the two that we could see not in their crates were 150 KW for both Chademo and CCS. These are being installed right beside the 16 V2 Superchargers.

Those should Give you the full 75-80 KW when at a low SOC on the Plus.

Right, so if Nissan can hit 80 kW without any real battery thermal system, then its a bit bizarre that Chevy can't hit at least the same or higher.

^^^Maybe they're just being more conservative, to enhance battery life. It's the average charging rate that matters to me rather than the max. rate, at least until the range and charging infrastructure increase to the point that sub-80% charges make sense for me. Ideally, I'd like to see a battery that can take at least a 1.5C charge rate to 80% or more, with no worries.
