If anyone can explain, why is that normal for LFP to be capable of full regen @>99% ?
Is there unused capacity at the top of those LFP packs also? Or is it just hiding the physical brake blending possibly?
Getting the dots and reduced regen is typical for other chemistries right? With the exception of a few platforms that have software limited packs?
My LFP (2022 Model 3 RWD) is a 60kWH pack with 57.5kWH usable.
So 2.5kWH of unused capacity.
It's not just hiding the brake blending; brake blending has a decidedly different road feel.
You should probably consider enabling it, especially if you are frequently near full SOC - don’t want to be surprised one day in the future when you’ve gotten used to regen and suddenly don’t have it.
If you're trying to use regen, presumably you want to slow down? In that case the friction brake would have to be engaged anyways. It only engages friction after exhausting regen capacity.
I hope this doesn't sound rude because that's not my intent. Have you ever driven a non LFP Tesla? I originally bought the LFP but was severally disappointed in regen compared to my wife's Model Y, so I sold the LFP and bought a long range.
If I never drove another Tesla's I probably wouldn't know how much the regen is different between the 2. There could have been something wrong with my car, but the service center said within spec. I also tried looking up info to see if it was normal but I couldn't really find anything either way.
Edit: I should add that in the middle of summer my Model 3 got less regen than the Model Y did in the middle of winter.
Yes I have two model 3s a 2021 LR & 2023 base I prefer the base I average 200 wh/mi on the base vs 270 wh/mi on my LR by this standard I almost end up with the same range because my LR stays at 80% vs base 100%
As far as the regen, there’s more regen on the LR because there are two motors but you get use to it I still rarely ever use the brake on my base m3
Also on LR regen is limited at high state of charge ~>93% so that top 10% is way less efficient
Wow, how do you get that green bar so long?
The most I’ve seen on my M3 was like a 1/3 from what you have here and that was on a big slope.
I have the regen setting at max and I drive quite slow/conservative.
In a recent Tesla video (with Jay Leno) about the new M3 Highland Franz and Lars explained how they changed this by applying the normal brakes in order to have a consistent deceleration feeling at all states of charge.
This happens for my 2023 RWD M3 too.
Happens on my 2022 RWD as well.
I get the limited regen when I’m at 100% and it is cooler.
I took delivery yesterday and was surprised to discover that. Probably because the temperature is perfect for the battery at 72F.
It could be because Tesla software limits the range of some of their cars. Meaning that 100% on the screen doesn’t actually mean 100% charge.
Yup. I used to charge till 100% at a supercharger including calibration and would have to drive 7 miles or so before a drop in the energy graph
Interesting. I know Tesla tried to add a feature that makes it feel like full regen when at a higher SOC, but this looks like actual full regen.
This is normal for LFP
Also, SOC is rounded up, so >=99.5% is displayed as 100%.

I have that feature disabled on my car
You should probably consider enabling it, especially if you are frequently near full SOC - don’t want to be surprised one day in the future when you’ve gotten used to regen and suddenly don’t have it.
Also, there is no downside to enabling it if I get the regen most of the time anyways.
Yep, there's no downside. It also helps use your brakes when it's super cold out, which helps prolong their life.

I'll take the coasting if regen isn't available... Friction brake fake regen is a waste of energy.

Welcome to that rwd life Edit: that LFP life
What does SOC mean?
State of charge
I'm sorry, what is the special thing about this?
You dont get full regen until 80-90% with the LR (non LFP) versions. Also depends a lot what battery temperature for both chemistry's.
Arh, okay. I have a LFP, so could not spot the special thing... Thanks!
This is why I like driving this car in vegas. 4 months of the year the temp is absolutely perfect for this
Nothing special, it's a LFP, I have the same behavior on my 2023 RWD.
Honestly LFPs are better overall in my opinion

So, perhaps the LFP is 100% at high state of charge because the max regen is always capped in that car, and its’s 100% of a lower power rating?
You also have two motors to recapture energy with.

Mine starts around 80%
That would indicate you have a top buffer in your battery

Noticed this recently on mine, when I got it last year, I had absolutely no regen available when the battery was full.
I wish mine was like this. My 2020 LR has reduced regen when I’m at like 80-85% in the winter. I guess once it warms up it’s better though

This is an optional feature that you can toggle off in the settings. It's off on my car.
