2022 Mustang Mach-E recently hit 250,000 miles. Zero problems.

250,000 Miles In, My Ford Mustang Mach-E Is Probably The Best Car Decision I Have Made Without Spending a Single Penny on Repairs, Except One Hiccup Related To My Phone

It’s not every day you see an EV, let alone any car, cross 250,000 miles without a single repair bill. What this Mustang Mach-E owner revealed might just change how you see electric vehicles.

"Not many people expect an EV to outlast most gas cars, let alone do it without needing a single repair. But every now and then, someone posts something that completely flips the script. That’s what happened when I read David Blenkle’s post in the “Mustang Mach-E Owners” Facebook group this morning. David had just marked a jaw-dropping 250,000 miles on his 2022 Ford Mustang Mach-E Premium Extended Range RWD, and even more impressively, he’s done it without spending a single penny on repairs. The car is still running on its original brakes, holding 92% of its battery health, and burning through tires only because it racks up serious mileage.”


Not my car.

So theoretically, you could drive it for 500,000 miles and retain around 84% battery health?

My iPhone is down to 80% after just a few years. WILD!

Yeah that sounds about right. The main difference is that EVs have hundreds or even thousands of cells in their battery packs along with a sophisticated battery management system (BMS) whereas your phone typically has just one battery cell and no BMS to manage its health so yeah, a phone will typically fail well before it should if it were managed properly. EV battery pack degradation typically runs about 1% per year on average so you're looking about 20 years before you hit 80% health which would still give you an extremely usable range.

I get that they arent directly comparable, but it certainly gives some perspective.

Cant wait to see what future EV battery tech looks like 10 years from now.

lol It'll look pretty much like it does today, just as current batteries look pretty much like they did 10 years ago. A 2015 Tesla Model S battery is pretty much the same as current Tesla batteries. Don't hold your breath for dramatic changes. Changes in the technology are incremental and iterative, not dramtic.

This may not be the right way to think of it, but I think of it like cellphone tech. It was a big jump from flip phones to iPhones, but now I only get a new iPhone every 3 or 4 years because the changes are so incremental. So we had the big jump to EVs and now the changes are just incremental and a lot of the changes are just external
cosmetics.

Yes.
This is why I really don’t worry about EV batteries.

If solid-state ever gets to the point of production for vehicular use, the expectation is that cell technology will have 10,000 charge cycles of lifetime before being down to 80% state of health.

Battery chemistry:
NMC (the early Mustangs) is around 2000.
LFP is around 5000.

The math:
A full cycle (full 0% to 100% to 0% charge cycle) means 350 miles per cycle for the Scout. With the NMC battery for the BEV, that’s 2000 * 350 miles = 700,000 miles to 80% state of health—still totally useable battery, just lower range. The Scout with an LFP battery will be 150 miles on battery, 5000 cycles, 750,000 miles. Solid state: 10,000 * 350 miles = 3.5 million miles.

Battery lifetime is not a concern now and will be even less so in the future, especially as manufacturers continue to learn how to optimize between battery lifetime and battery performance.
