I'm not sure if you still have your Mach-E (if it is still at the dealership or if you sold it already?), but I'd be really interested to hear what your final mileage and battery state of health ended up being. I think you must have had one of the higher mileage Mach-Es and probably DCFCed it more than most people.
At that rate, if degradation was linear (and we know it isn’t) we would expect 70 % SOH at about 176k miles, sound about right?I still have it. I hooked a tiller up to the back and use it to plow the horse manure into the pasture.
Definitely better then sending it to the glue factory.I still have it. I hooked a tiller up to the back and use it to plow the horse manure into the pasture.
I'm gonna put on my tin foil hat and say that I think one of these days we're gonna see "battery gate". I just have a feeling that these companies are going to do whatever they can to prevent warranty replacements, even if it means fudging numbers (software).
Battery degradation also depends on calendar age. Actually for most vehicles it will degrade mostly from calendar aging rather than mileage (unless you put more than ~20k miles per year).
SoH <70%. Which also means the power output will be noticeably reduced, and you’ll probably get the weird effects near the bottom of the pack like suddenly losing 5% after merging on the highway (due to high internal resistance). Most of us have probably seen the “suddenly losing charge” effect with a phone or laptop battery that was going bad.
Yeah, but the way it came out was "If you guys haven't noticed I'm always around 50% SOC". My opinion, and that of other of commenters (cited), is that he should have never said anything. He didn't need to let people know he's OCD about that because it comes across as "This is what you should do". That's also because he cited a guy who has an entire list of do's and don't for EV batteries (cited). He's respected by a lot of people and his videos often appear for people looking to purchase an EV. When those things are said, and then it came out the he "yelled" at a Rivian owner for being at 85% SOC (cited), it just doesn't bode well for potential EV buyers that are on the fence. Additionally, Kyle isn't keeping any car for more than a couple years, so why does he even care?
You might not be worried about the health of the battery or warranty since you'll never hit the years or mileage, but for many people (myself included) they'll have the car well past the warranty period and want to have a car that can continue to meet their needs. For example, for the Mach E it's 8 years or 100k miles. In my opinion 100k miles isn't an exorbitant amount of miles for someone to hit before that 8 year period. In my case, I've got 8k miles and I've owned my Mach E for about half a year and work from home so I don't even have the typical commute that many would have. So I want to be considerate of the battery health so I don't get to a point where I hit the 8 year/100k miles mark and I'm just barely above the threshold for the warranty with the realization I'll have the car for another 4-5 years or 50k-100k miles.
While there's gonna be outliers, and that's understandable, age is going to kill the battery before miles. I have 41k on my MME and I'm at 93% SOH. I would hit the 100k mark well before the 8 years and at well above 70% SOC. The mfgs didn't give you a warranty that you'll ever likely use, especially at the cost of a replacement battery. They would go out of business if they did. The warranty is based on the absolute harshest conditions. If you want to baby your battery go for it, my larger point is that everyone who says "you need to baby the battery" is just hurting EV adoption. It's like those who say never go below 1/4 tank of gas because your gas pump will go out. I fill up an ICE vehicle with 10 miles of range left. I've never had a gas pump go out, but if that's what Joe wants to do, have at it.
Not even an issue at 30,000 miles unless you notice the significant reduction in mileage. But you also have to take into consideration all the factors that affect these batteries. Such as outside temperature you're driving habits, and so forth. I have a 2023 Mach-E select with 36,000 miles on it and the only time I see any difference is when the temperature outside changes dramatically, either extremely hot or extremely cold. But when I get to around normal temperatures and charge I get the regular mileage 180 MI for 80%.
Yes.
