Will the latest and best battery chemistry be the same 3 years from now?
Sponsored
My math was bad.….thanks for fixing it.Not doubting you, just curious how you came up with that number?
The only thing I could come up with is charging at 350kW/hr for 10 minutes adds 100mi range (350/6=58.3kW added). If the range is 400mi that would make the battery pack roughly 233kW which would make 1.7kW/mi which sounds very very reasonable (though a 233kW battery pack is outrageous).
Edit:
Here is a link showing that the Ultium system can have up to double the energy density of normal Lithium and that they plan to use 200kW (which is a round number so I assume an estimate) batteries in their trucks.
"With each 24-cell Ultium battery module good for 8.9 kWh, expect to see six-module packs rated for 50-kWh usable capacity in the smallest, lightest vehicles, and the mighty 200-kWh (usable) pack topping the range in the GMC Hummer EV."

Not sure... what will the inflation rate be the next 3 years?Will the latest and best battery chemistry be the same 3 years from now?
That's how they get the mid-gate.I'll never understand why they kept that cab-to-bed transition detail from the Avalanche. That looks so stupid IMO.
According to the GM reps:Well it's more like 1.5 years by the time the WT comes out.
There is a path, and it is possible. That's all I'm saying.
They must have pulled everything forward about 6 months. Last I remember, the consumer WT wasn't supposed to be available until spring/summer 2024.According to the GM reps:
Fleet / Commercial WT EV is coming out this summer.
RST for consumers coming out fall.
Consumer WT is coming out winter 2023.
TFL put a video out on this today. The 400 mile range is only on the WT4 trim which starts at $79k. Even WT3 has a lower range, though they didn't have numbers for it.I thought the same thing because that's logical...however:
"The peak charging power of the Silverado EV is 350 kW as standard. GM expects ten minutes of charging through an 800-volt DC charger that can charge at up to 350 kW to provide a range of approximately 100 miles. The company is estimating a range of over 400 miles on a full charge, hinting that it’s not downsizing the battery pack (24-module pack). The Silverado EV WT includes bidirectional charging support, so, it can supply up to 10.2 kW of power from its battery pack to charge electric equipment or even another EV at the job site, while not leaving the driver stranded after a day’s work."
"The WT and the RST both get about 400 miles of full-electric range. A front trunk, which is standard with both models, provides even more storage capacity."

(No clue if that's a reputable source...it is the internet)
There is no mention of different battery sizes or a SR vs ER model. Ford always clarified in the Lightning the difference.
Well, given the production rates of the Hummer EV and just about every other Ultium EV, does it really matter if they are only making 10 or 20 a month?Not sure... what will the inflation rate be the next 3 years?
How skinny margins is Chevy willing to take to get the "starting at" headlines like Ford did?
Does it really matter if they only build less than 5% of their EV truck in that config? We are likely just discussing a unicorn config.
I dont know, and you dont know. Shine up your crystal ball... and I'll shine mine. Its just conjecture.
The problem is I think there are a lot of overly optimistic people trying to rationalize the price lower because it what they want. Not because it is likely.
My guess, there are very very few Sub $50k Silverado EV's ever made, if any. If there are any at all it is done as a loss leader in limited quantity or it will be neutered in some major capacity like battery pack size.
Yes. Five years? Maybe not, but it is not looking promising for anything to overtake Li-ion NMC as the best chemistry for the most energy-dense (and fun) chemistry. LFP may become more popular as a platform, but it will not have the umpf of NMC. Forget Si-ion and solid state as near-term replacements.Will the latest and best battery chemistry be the same 3 years from now?
Silverado EV will NEVER have 200kWh battery. 160kWh is max.There is 0% chance that they are going to sell a 200kWh battery truck for $42K. I doubt we'll ever see anything at that price.
They've already said that 3WT/4WT (shown in the video) starts at $75K which might have a 200kWh battery. We also know that the volume RST trim (which is roughly equivalent to Ford's XLT trim) will be $107K.
Payload is 1300lbs in 3WT/RST.
What, may I ask, leads you to this definitive statement? Do you not believe a battery could never be packaged in the frame that would yield this result, or do you truly believe that no battery could ever exceed 160 kWh? I ask because I am currently testing a 3 MWh battery we are designing for a customer.Silverado EV will NEVER have 200kWh battery. 160kWh is max.
Uh, “m” is milliWatthour. I think you meant Mega with a capital M! So 3000 kWh, not 0.000003 kWh.ask because I am currently testing a 3 mWh battery we are designing for a customer.
I can see them going with 160 since that should let them squeak into 400 mile range. But I think we'll have 300kWh "max tow package" trucks in less than 15 years and 200kWh in less than 5 years. We'll see.Silverado EV will NEVER have 200kWh battery. 160kWh is max.
