They don't read this form, they know little, lol.Odd there was no mention made of wireless communication, repairability to replace a bad brick, and compare those to the "others" they have seen...
Well, all you need is to look at the past. Tesla was the first EV in this millennium. Then was the Bolt. I'm ignoring the Leaf because that was a piece of crap from day 1.EV's look good on paper. EV's look really good if you want to save the planet and go Green. EV's are excellent for thumbing your nose at Middle East/Russian oil and large oil companies. Etc. But since EV technology is so new and yet unproven over a long period of time, what you get today inside your EV, might not be what you get inside your 2025 EV or 2026 EV, or 2027 EV, etc. It.s not like EV manufacturers are building EV's blind but more what looks good today might not look good 16 months from now. Be it current EV's/batteries in production, on the blackboard or AI developed. Maybe I'm over stating things and once we get a solid picture of long term EV batteries - everything will work out.
Yet for now (being 1 to 5 years) I'm leaning towards a hybrid motor for stability and hopeful high resale value. Yea - EV's are the future but starting to wonder when future becomes a 99% guarantee that what you bought at GM, Ford, Toyota, Honda, etc., (EV wise) holds up long term as a good purchase versus a 2023, 2024 EV purchase being devalued because of faulty this or that, or worse some new and better EV/battery technology coming down the road. Change is good but right now things are changing too quickly and everyone seems to be going in different directions regarding EV development. Boy this sounds like AI baloney.
(Weird stuff I learned years ago: Unnaturally aspirated combustion is literally as old as steam engines. The first practical work-doing steam engine of the modern age dating back to 1801 and 1802 used the exhaust from the cylinders send up the chimney ("blastpipe") to increase the flow of air through the firebox, and it was enough boost that "lifting the fire" was a hazard to be avoided with careful valving.)So I don't think there's much to worry about. Look at a turbocharged engine... That exists almost forever now, and you'll rarely hear someone say "I won't buy a car without a turbocharger".
"But Tesla does aluminum."Steel battery pack frames are far stronger than aluminum.
Yup, I wonder if GM will ever make improvements on this design? /sGM could definitely do better on the number of components for the battery carrier.
"We can't say anything negative about that... please don't dwell on that, lol."Two parallel 400 volt packs is what allows GM to support 350KW charging
From what I read, almost everything supports the heat pump system.The contactor assembly is complex, but I suspect this is to support the heat pump system
It would be awesome to hear the running commentary of the GM engineers on cost/benefit/performance criteria involved while these two pick their way through the pack. We never will, but it would be fun. The GM people might even agree with many observations but post out other factors the two from Munro missed. Keep in mind that Munro's ultimate goal is one part instead of say 100. Laudable, but there are other factors to consider. There are trade-offs.They completely missed the coolant structure. Those plastic runs are compressible and will expand when compressed. This allows GM to tighten down the battery module to prevent water leakage.
"But Tesla doesn't do this with their battery battery pack. You just replace the whole pack. We don't understand, this must not be a good idea."GM has definitely designed to swap out modules, thus the capacity loss when a cell has a problem and won't hold a charge.
"But with Tesla you just replace the whole pack if something goes wrong..."The nylon lines appear to be designed to last more than the standard 10 years of a cooling hose.
"But Tesla uses aluminum"Copper is a better conductor than aluminum. Makes for a far better buss bar.
At a minumum, they did not delve deeply into engineering design tradeoffs.These two guys are clueless when it comes to engineering design tradeoffs.
Those 23 OSB sheets weigh about 1700 pounds (or the approximate weigh of a Hummer EV battery pack), lol. Plus the plywood sheets.For those wondering why GM chose steel over aluminum.
GM is actually in the process of replacing the packs in the Hummer to resolve a water leak issue.... they are going from version 1 to version 3 packs. xDbut I suspect that and others will be addressed over time as GM does iteration, 2, 3, 4, etc.
