Every time I see the timeline, I get discouraged.
I'm 74 now so...

Hey, the average lifespan of a man is 70, so you’re already beating the odds. That’s promising!

I think it depends on timing and what the used market looks like in my area, but have been eyeing up a Volvo C40 or possibly an Ioniq. I'd jump on a F150 if I could convince my wife lol.

Edit: forgot the ID4

I did finally find a deal for a used '24 Ranger with 25k miles left on the warranty for $15k less than a new one. Pretty stripped with almost no bells and whistles but at least I have a truck capable of my immediate needs for the moment.

It kinda makes sense with the R1S now that there’s an R2. I wonder if they would ever make a R2T.

Interesting, and not surprising.
This isn’t an impossible problem to solve, but it’s also a problem that requires some new ideas.

The standard for estimating battery state of charge (SOC) is the voltage. But the difference between an LFP cell voltage at very low SOC and 100% SOC is very small. So that standard doesn’t work well for automobiles—it’s fine in other applications. The standard for knowing the SOC to higher accuracy is counting coulombs. But the count isn’t perfect, so the method means SOC drifts based on use, so unless drivers are willing to drive down to very low SOC (5% or less) and then charge all the way up to 100% without using the battery, there’s no other great way to reset the drift.

Oh, I'd seen they were dropping it, but wasn't aware of the calibration issue. But it is a bit of a bummer, as I had actually somewhat considered an R1S for a while, and the Standard was going to be what I was going to go with, as it was the only one even sort of close to the price point I wanted.

I understand the need to differentiate between the R1 and R2 series, but personally I'd have been quite happy with a de-contented R1S. Removing things like the electronically controlled HVAC (even the vents and where they are positioned/blow air is controlled via touchscreen and electronics), the electric releases for the center console, the doors, etc. Then of course a bit less fancy on the inside.

But I suppose that won't happen now (or possibly ever), because of the R2.

I guess charging to 100% will reset the drift - but not account for any lost capacity (which is a second issue).

Yeah, that’s a separate issue. And the LFP batteries are more resilient to long-term capacity loss compared with NMC, but honestly, even the 2000 cycle lifetime of NMC is more than enough. An NMC battery’s 2000 cycles on a Scout will mean 700,000 miles, or 38 years if cycled once a week before it’s down to 70%-80% capacity.

The tracking algorithms for the battery state of health are patented, proprietary, and…wrong but good enough.
(All models are wrong, but some are useful. — George Box, 1987)

Because the variety of algorithms there is now an SAE standard in the works (J3257). Similar to the wild claims of towing capacity up until the mid 2000s, it’s time for a standardized way of determining the state of health of an EV (PHEV, EREV, BEV) battery.

Sounds like a way to go to a mid-upper level R2 to make better margins

This seems like good timing with gas prices going up and all. 300,000 EVs coming off lease.
