90%+ Battery Capacity After 250K

[superdave80]

No.

Have you ever actually removed and broken up an EV “battery” or seen an MMe “battery” removed?

To put it in numbers-
They treat a 300 mile range car like one with 250 in hopes that in 10 years it will still have 270 miles of max range instead of 260.

I think you are getting that backwards. People want to have the 300 mile range for long trips, so they treat it like a 250 mile car when they are doing their short range/daily driving.

What do you think we are losing by charging to 90% when we only use 10-30% on a daily basis? You gain nothing by charging the last 10%.

You gain horsepower.

The Mach E loses noticeable horsepower at 90% charge and significant horsepower the lower you charge.

At the end of the day, the studies have shown a pretty insignificant range loss when you limit your charging even after 100,000 miles or more. A couple percent difference maybe.

So you spend years obsessing about protecting your rang for what? An extra 5 miles of range that you also NEVER use?

How many times have you gotten below 10% charge in the lifetime of owning the car? For me it’s zero.

But even if you do, if you baby the car you end up with 10% charge vs someone who charges to 100% all the time ends at 8% for the same trip?

So do you stop to charge every time you hit 89%? If not, why are you busting people's chops if they charge to 90% and go about their day?

Yeah, I do. I keep mine at 95% and charge at home regularly.

I’m busting chops because people seem to be obsessing and/or worrying and they don’t necessarily need to. Unnecessary anxiety is a bad thing. Trying to help here!

Interesting to see a couple of modules lifted out, but still not a cell change which just isn’t practical or even possible as far as I can see.

Interesting stuff about the cooling system having just been involved in some transmission cooling system maintenance.

All not really rocket science, though, to the skilled, trained and experienced.

I've never had a problem travelling the speed limit when my MME was at 60%. Of course I wasn't pulling a heavy trailer or driving 90 mph like some of the idiots I see on the road. This car seems to have more horsepower than most cars on the road even at 50%. I don't believe I've ever heard a complaint that the MME doesn't have enough horsepower at 70% charge. I keep my MME between 40-90% for daily driving and charge to 100% as the manual recommends.

Ironically, horsepower is a lot like range.

You don’t use all of it all the time. But you use ALL of the horsepower waaaaaaay more often than you will use ALL of the range.

I paid extra for the GTPE for better acceleration. It’s definitely faster and more fun near full charge.

People are asking “why charge above 90%?” Horsepower is the reason. If that doesn’t matter to you, it doesn’t matter to you. But it matters to some.

The counter argument- “why you shouldn’t charge above 90%” is so that you don’t have an extra 2% degradation at 100,000 miles, just doesn’t matter to me. I also believe that it shouldn’t matter to most of us as we won’t have our cars then and it would be highly unlikely to ever impact us.

Maybe some people here regularly drive their cars down to 2% charge, but that would surprise me.

But people flooring their cars occasionally? Yeah that seems WAY more common.

I saw that somebody liked the hp in their car down the road the other day as they left half of their tires on the road. Acceleration marks weren't pretty. I got past that about 50 years ago.

Sad, it’s still super fun! You should give it a whirl sometime again. Relive the glory days!

The individual modules are fairly easy to take apart into their individual cells (Monroe did a teardown of them a while back). The only hard part is that the cells are spot welded onto a common metal plate. Not sure how easy that would be to re-weld the new cells into place.

The average person wouldn't be able to do it, but I could see someone setting up a business to collect old modules, strip out the bad ones, and replace them with 'good' used cells from other modules. But there won't be any real demand for it until the first Mach-e batteries start to go out of warranty around 2030.

I have seen some videos on businesses (I think it was in UK) that were setting up to recycle batteries (not Mach-E's but this just a general comment on the idea). they did do battery rebuilds and recycling of batteries that couldn't be reused.

Do you know what their biggest problem was?

Getting old battery packs in the first place!

Between batteries lasting for a very long time, and the secondary use market and the fact that EVs are pretty new, they were having hard time getting enough batteries to make it profitable.

Farei um post sobre isso, mas meu Ford Mustang 2022 tem 108 mil quilômetros e está 92% saudável.

Don’t think it’s the premium option required.

I seem to remember just setting up a dashboard for my car in the Car Scanner app, making the right selection/s for the values you want to see and Presto! You’re there.

Yes, I think the trick is "making the right selection/s" which is the ultimate question. I am running Car Scanner app, with the car setup as an EV, but I am unable to find a setting for HV battery SoH.

Any and all relevant advise welcome. Trolls will be ignored.
