      Going back to the Ultium platform. I said that the batteries on the trucks are stacked up on each other and amongst other things that make it an 800V system. While true that the batteries on the Escalade, Hummers and Chevy EV pick up truck ARE stacked on top of each other, that does NOT make the system an 800V system.  The fact that the two battery packs are connected IN SERIES makes them an 800V system. And that was what I was inferring to when I said "amongst other things".   I read somewheres that GM knew to make the Ultium platform an 800V system at launch but figured the EV charging system was not capable of charging at those 800V fast charging speeds then so a 400V system was good enough.     Again, I do not know if this is misinformation.    GM went to dual 400V systems on two battery packs connected in series to emulate an 800V system on the trucks in that GM knew that range and charging speeds and all that where GM has an advantage to other truckish EVs were going to be a factor.  The EV range on these truck EVs are amongst the best EV ranges in the world. Never you mind that there are two huge battery packs with a shyte ton of KW/H to them making at least one of the three trucks, the Hummer EVs, a very piss poor efficient EV.  (The Hummer SUV and the Hummer pick-up are blended into one product in my rants)  Some folk talk about how bad the efficiency is.  But most applaud the range of these EV trucks.   Also, these two huge battery packs make for extremely heavy EVs.  I would assume the most heavy of ANY civilian EVs on sale to date.

      In other news. The usa still sucks shyte!!!    If its a Democrat problem, then arrest all democrats on  raping women, sex trafficking and sex with under age girls.   Yeah about that.... Trump is also on that list so... Lets get this right.  The main idea on this is that trump is on that list...  And it would be your president.  Shameful, disgraceful and disgusting. Unlawful, unruly and ungodly. Not trustworthy, not ethical, not honourable and quite frankly, quite phoquing scary that americans are capable of accepting this shyte as their representative of their country and people.  ALL americans...

      GM's Ultium formerly known as, is actually a 400V system.  The Chevy EV pick-up truck, the Hummer EV and the Escalade are dual 400V set-ups working in tandem to emulate a 800V set-up.  I guess the way the battery packs are set-up in that truck platform. The batteries stacked up one on top of the other. Amongst other things, I suppose.  The other Ultium platformed EVs with the single battery pack is just a 400V set-up.  But I also read somewhere that GM has an 800V successor platform ready to go on sale in China right now.  But is stalling due to reasons. Stalling here and there...   Rumours and/or disinformation it could be though.

      The sad part was the Auto Industry had agreed on the 800V standard before Ford went forward with the F150 Lighting and your right Porsche Taycan took the standard and brought it to market first. Ford like so many other auto companies had bought the tear down on the Tesla and knew what Tesla was, why then only build to their 400V equal when the spec was agreed upon to 800V. GM did this and was not that far behind Ford in bringing their 800V EVs to market, so I feel Ford took short cuts to be second when they could have built better accepting that Rivian was already out at 400V and they could have hit the market with 800V on par with GM at the time. Will be interesting to see what happens as the Koreans have stated to have mid-size and possible full size 800V EV pickups as well as Hybrid pickups coming out soon. Interesting times for sure.
