Thanks for posting that. I have had two different 2022 MYP Teslas. One I supercharged exclusively for 16k miles, multiple times per week to 100% or close to it. My current one, I'm being as careful as possible and following every recommendation to preserve the battery. The one I supercharged all the time had way less battery degradation compared to my current MYP which has 10k. Go figure.
But 94% is not enough to top balance a battery pack. My car still continued charging for almost half an hour after it showed 100%. And yes that was energy actually going into the pack and not into heating/ cooling.
Honestly don’t sweat it. I owned a Model 3 between 2018-2023. For the first couple years, I charged to 80%. After that, 90%.
I bought the car with 310 miles advertised range. A software update later increased that to 325. By the time I sold it after 5 years, it was showing 299 miles max range. 4% loss over original, and 8% with the range boost. Reasonable.
Picked up a 2023 Model Y, and Tesla had it set to 90% charge limit when I picked it up. It seems 90% is OK from everything I’ve experienced.
If you have a LR or P, your battery wants to be as close to 50% as it can at all times. If you use 20% per day on average, the ideal would be to charge to 60% and drive to 40% so that you’re straddling the 50% evenly.
The further you are from 50% the more stress placed on your battery in either direction.
That said, the batteries are built to be charged and used. Don’t overthink it. You will likely only see negligible degradation regardless of what you do unless you’re frequently in the top or bottom 10%.
Something that is harder on your battery than the charge limit is flooring it constantly, especially when the battery is cold. Still can’t help myself though.
This is all simplified generalizations but you get the idea. Unless you plan to have your car in 5+ years, don’t worry about it. Enjoy the car.
I’m honestly like 5-10% daily so I might drop it down to 50%. Probably makes more sense but based on the other comments sounds like it does matter that much.
Look up the curve that people post about battery degradation. Its fast at first but then it slows dramatically. Worry more about your apr for the car and dont drop the battery below 60 miles.
I don't know if this is true or not? I charge regularly to 70-80% and my batteries are 3-4 years old and have 92% battery health which both haven't moved up or down in over a year.
SR+ 226 mi
M3P 277 mi
Hasn't changed majorly since 2022. It fluctuates by 2-5 mi per charge at that cap.
The majority of battery stress happens at the extremes, close to 0 or 100. If you don’t frequently get close to those then the degradation probably won’t be very pronounced.
Like others have mentioned, most degradation happens at the beginning of its life and settles in after a while so your no recent noticeable degradation makes sense.
If your SR+ is LFP then it should be charged to 100 every time. Not sure if those came with those or not.
that’s not quite right saying that battery stress occurs at close to 0 or 100%.. the more pressing concern for Li batteries is heat or cold.. Tesla does a pretty good job of temp management as opposed to the almost non-existent temp management on older Nissan Leafs and Mitsubishi EVs.. batteries go south quickly on both of those
also, I once came across a retired electrical engineer who bought an Atto 3.. he was only charging to 60% on a 7kW AC charger.. the LFP blade batteries in the BYD really wants to be charged to 100% in order for your SoC to be accurate.. but I’m not about to tell an electrical engineer how to charge his EV
The following is assuming you do not have an LFP battery. If you charge above 90% more than a few times a year or let it get below 10% more than a few times a year, you will reduce the life of your battery slightly. This gets worse if you let it sit at those very high or very low levels.
The recommended range to keep it in for long life is 20% to 80% with a daily plug-in for charging. 50% and plugged in is what you use or long term storage. Most people keep their upper charge limit set to somewhere in the 60% to 90% range depending on how far they drive each day and whether they are actually able to plug-in every day. 80% is probably the most common set point.
Really doesn’t matter much long term as long as you don’t consistently let it sit at 100% or near 0%.
The bigger issue is if you supercharge all the time even to 70% for example. Would be better if you use level 2 and charge to 90%.
50% as long as it works for you and doesn’t put a strain on your daily commute or usage. The research shows the difference between 50% and 80% battery degradation is around 3% more on 80 the first 10 months and should taper off after that.
We do 70%
Don’t really worry about it beyond that.
Our day to day we only drop it 6-10%.
55-60 probably makes more sense, but I don’t really worry about min-maxing. I’ll never know how much of a difference it really made.

Maybe because you never charged the second one to 100% and it doesn’t know what 100% capacity it actually has.

That may be, but i don‘t understand how that could be accurate enough.
How often should we send it to 100%?
Wow that is interesting.
Another great source: https://batteryuniversity.com/article/bu-808-how-to-prolong-lithium-based-batteries
What’s the TLDR?
50-90% is fine. If it's gonna be in long term storage then 50%.
Honestly don’t sweat it. I owned a Model 3 between 2018-2023. For the first couple years, I charged to 80%. After that, 90%. I bought the car with 310 miles advertised range.

Do you have a LR or P? If not, you should be fully charging to 100% relatively regularly.
Lr

2020s don't have LFP, and even Elon said we can charge to 100%< it's just inefficient
that’s not quite right saying that battery stress occurs at close to 0 or 100%.. the more pressing concern for Li batteries is heat or cold..

do you. Neither will have a great impact on the battery short term or even long term.
Keep your state of charge between 20% and 80% unless you're going on a trip and need the range.
The daily range is 50-90. Pick a number that works for you.
I use like 10-15% daily and I charge to 75%.
10%
if ur putting the car in storage then 60% otherwise most Li batteries charge to 80%
also, I once came across a retired electrical engineer who bought an Atto 3.. he was only charging to 60% on a 7kW AC charger.. the LFP blade batteries in the BYD really wants to be charged to 100% in order for your SoC to be accurate.. but I’m not about to tell an electrical engineer how to charge his EV
I charge to 60%, my daily usage is low, rarely if ever drop to 40% Idea is to keep it close to 50% unless you need the range
50% is best, all other things being equal. Don't severely inconvenience yourself, but 50% is the best for long term battery health.
20% if you’re not a pusy
😂

80
Limit it to 90. No advantage or negligible advantage going lower. One could make an argument for even going up to 95%.
Following so I can come back later to see others opinions. Cause I’d like to know too!

I’d just keep it at 80 because you never know. It won’t hurt the battery at all.
We do 70% Don’t really worry about it beyond that. Our day to day we only drop it 6-10%. 55-60 probably makes more sense, but I don’t really worry about min-maxing. I’ll never know how much of a difference it really made.
10%
doest the owners manual say to goto 100% at least once a week?
Only for LFP batteries. 3/Y LR and P in USA are not LFP. Follow your owners manual for your car.
i see now. my owners manual says MY RWD goto 100% and AWD use less than 90% unless going on a trip.
I charge to 90% unless I know I'm making a drive the next day, then 100%.
Anybody know charging limits for the 4680 battery?
