No 800V architecture for Max Pack - confirmed

[Kieran]

The 800V cars seem to have a much easier time charging at 200+kw.

Yes, but I'm curious how much wear and tear this will be on those batteries. There's no doubt that slow charging is easier on current tech batteries. (Many/not all) early Tesla owners learned the hard way that too much supercharging accelerated the degradation of your battery, resulting in significant range loss in just a few years of ownership. My own S75 lost about 12% in the first 2 years because I was supercharging all the time. Then I got a home charger and degradation has plateaued.

Hummer charges fastest until somewhere in the 60% range where it significantly falls off. If we weren't stopping for an extended period of time, 20-25 minutes tended to be the sweet spot for charge time. Then hop to the next one.

That's consistent with every EV I've experienced so far. 15-60% is optimum. After 60% or so, it gets painfully slow. It seems to be true regardless of capacity or voltage, too. I'm not sure why. I can charge my 2017 Tesla S75 to 60% in about 20~25 minutes too, and it maxes out at about 130kW charge rate at around 25-28% SOC. The Long Range+ model S I demoed was the same, 60% in about 20 minutes, and that was with the higher power (250kW version 3) superchargers. I've heard the same from model 3 owners, and from a Rivian R1T owner friend of mine.

This is why I keep saying we need the 60% capacity to be the target range of the vehicle, or something. A 500mi range car would get 250 useful miles between stops on a long road trip (charging from 10-60% each time) which would be a 15-20min stop. Some cars advertise something like "charge 200mi range in 20 minutes" which I think is a lot more useful / informative than reporting the max range for driving from 100% to 0% which no one does, ever.

Yes, makers will tailor their bms resulting in different charging curves. I honestly think some like to push a peak rate for a bit to show the customer the fastest charge rate, even if it results in a less area under the curve for a given time.

But the biggest question is how to make money from fast charging... Or put in this way: How do you make money selling water from a expensive vending machine???

For future proofing (yes, I know that term is "cringe" in the tech world). I like to keep my vehicles for 10+ years, my 4Runner is 11 years old with 160,000 miles. I've cancelled my pre-order for the R1T. I'm going to get another ICE vehicle, maybe a Tundra or Sequoia, until EV towing range and charging infrastructure are more robust.

Fair point. My intention is also long term, but the lack of quad max 800V made the drop to Quad Large easier, but not super thrilled having been dragged along to this point. I still wouldn't have had a vehicle any sooner however since delivery in Vancouver only just started.

As another member mentioned, I may get the Road tires and aero rims in addition to the 20's for added efficiency when road tripping.

I just want them to release these range estimates already. That will be the clincher for so many people. And if it’s not 355-360, I’m going quad all the way.

you can already get 330 + on conserve mode with quad motor so why wait.
