Yep, 80% seems to me to be a good daily target for myriad reasons including that one. I've noticed it a bit more on the Tesla as that regens more aggressively than my truck so you notice it a bit more when it's not.

 

Agreed, you definitely don't have to charge every night. I just do, as I can't be bothered with timing it based on current SOC.

 

Some of you may have heard this story already but I thought it was pretty cool.

An F-150 Lightning owner spent 26 months "breaking every rule" of EV ownership by charging to 100% every single night for 60,000 miles.

 

Of note, that battery analysis was done with FDRS, the platform Ford dealers use for diagnosis and module reprogramming etc. That’s the information Ford techs get when they are diagnosing battery issues etc. In other words, it is Ford’s own assessment of battery health. I don’t have FDRS, but I do have a utility to get some of the data points via the OBDII port and mine also reports 100% health. Mine will be four years old in August. There is a big reserve buffer on my battery, roughly 13 kWh, so that likely factors in as does the fact that mine is mostly L2 charged and mostly within the sweet spot ranges. There’s been no indication that Ford has been quietly releasing buffer, either, the batteries just seem to be holding up quite well. There are obviously a number of people who do report degradation on their lightnings, but it’s generally been just a few points.

 

I'll take bets on that costing $140k. Its not going to.

Again...most people who buy a family vehicle want to use it to travel with their family. Thats not an unusual thing no matter how you try and spin it.

Thats the second highest in the country only to CA. In 2025 overall it was about 7% and that includes people rushing to buy them before the tax credit expired. Thats not enough to sustain the investment all of these carmakers have made into EVs and you know it.

I have owned way more Lexus vehicles than you have Paul, and I was a consistent customer of the brand for a lot longer than you. So please spare me. I'm the one trying to buy another Lexus right now...where is the Lexus EV in your garage? Did you even consider an RZ instead of your Ioniq 5 or Model Y? No. Why? Because its not a compelling offering.

Just look at the competition, the Germans blow Lexus out of the water when it comes to performance and luxury, and EV performance is just the latest example of the same issue.

 

Yeah, the EPA needs to step in and set up some rules for how "battery health" is calculated to prevent companies like Ford from hiding degradation in a hidden buffer. Degradation isn't linear anyway, but buffer shenanigans make it look even less so.

 

Right on cue! And still failing to understand that battery SoH and battery degradation aren't the same thing. While it's almost certain that you never bothered to read it, your argument is with the article writer for misusing the term, not with Ford for correctly understandng what the measured state of health of its own EV battery according to its own factory diagnostic tools actually reflects.

 

Wrong, I'm not failing to understand anything. Battery degradation is physics. SoH is a made up marketing term that can be almost anything they program their algorithm to show. Automakers shouldn't be allowed to hide battery degradation in a buffer and mislead the people that think SoH means something. It implies that it is a measure of degradation, and it clearly is not in Ford's case.

 

And again, and speaking directly to your lack of knowledge, in this specific case the SoH is never made available to the user without the owner digging into data that can't be accessed via any other means than via OBDII data extraction. In this case, it's an engineering term, not a marketing term. It is not a metric meant for anyone other than Ford engineers and techs. And in the case covered by the article, it was those techs who provided the data, not the user.

I think you're just envious because mine's quite a bit bigger than yours.



 

Everybody and their mother has an ODBII reader. Ford knows this and puts a stupid, misleading number out there to fool the idiots of the world into thinking their battery is good as new after 50k or 60k miles. Actual degradation is what engineers care about. IF they didn't want you to see it, it wouldn't be readable via ODBII. There is plenty they hide that can't be read by ODBII.

Not sure why your panties are in a wad over somebody wanting standardization. Just report the 100% range of the entire battery (including buffers) and let people see how it degrades honestly.

 

pretty simple. rz wasn't out when i got the ioniq. y (and no other) has full self driving which was the appeal. but yeah, the rz really had poor range (improved now) and the software wasn't stellar either. but this is all irrelevant as i'm not the one after a 'family' 3 row suv as you've pointed out a 100 times.

as i've said many times and you've confirmed over and over and over... the tz is not what you want, so why not just let it go?

 

Right, it was an inferior product which is why you didn’t consider it. Pretty sure the RZ was out, it came out in 2022 as a 2023 model.

It’s not irrelevant because you are accusing me of being “as usual” blanketly negative about Lexus when I have been a staunch fan of the brand and an excellent customer spanning 7 vehicles and 20 years, and am way more likely to have another Lexus in my garage in the future than you are.

Stop arguing with me about my situation and my criteria like I said before. You keep making all of these snide comments about it trying to paint me as being unreasonable and a fringe case and it’s ridiculous, as several other people have also told you including your fellow admin. Let it go.

Im here discussing this vehicle with my fellow CL members. You keep making it about me.

 

TZ is great. I would trade in my gx if it only had 301 mile of range. 300...meh.

 

See? Lexus was so close!

 

lol, no idea why you're making this about me, i'm not a target customer for a tz.

ok not lexus as a whole perhaps, although once you went mercedes, pretty sure you posted a mountain of comments about how bad the ls500 was.

sure ok. too bad you won't stop repeating about the family trip a thousand times and how you think th tz is 'pathetic', but ok.

nice try. you keep making it about you as the archtetype tz customer needing to get to the middle of nowhere where there's hardly any charging available (not lexus' fault).

ok, i'm done.
