Tesla has only one charging advise. This charging advise is the same regardless of the chemistry tou have in the cells. Its also the same if you live in a very hot or very cold climate. Tesla do not at all aim for the lowest degradation. Tesla tries to male sure you do not run out of juice at...

It would be interresting to hear about this car, about the battery and range etc. Could you report back when you know?

Cyclic aging is very very small during normal operation. We can reduce the cyclic aging by using smaller cycles and do these at lower SOC. 10% DoD series. Lowest degradation is 35-55% SOC in this test. On a Tesla display this is around 32-53% displayed SOC due to the buffer. Even using the...

Except from short range, no, I work far away from home and aim to arrive with low SOC. I still have a little to be able to cirmumnavigate any accident etc, as I go live into readinnes when I arrive at work (not good to be late). So I aim to arrive with ~ 10-20% and I have the car parked not...

I often use that picture to show both how similar the three chemistries behave and show a good average for Calendar aging for NCA. That picture is very good for these two things, but it is not the conclusion in all aspects. The very high droop is not present in all NMC test, in many cases it is...

Most answers already given. For longevity you would like to have the battery below 60% as much of the time as possible. The cells do not need to be stretched. Ever, really. Low SOC and small cycles reduce the degradation. The technique to ”stretch” is to help the BMS to estimate the battery...

[Sense] is subjective in this case. If longevity and to reduce degradation is the goal, low SOC is preferable both for calendar- and cyclic aging. You can not reduce degradation by charging past 55-60%. As long as the energy from 55-60% or less is enough for daily driving (chemistry...

Nope, its not. This is how calendar aging is affected by SOC and temperature. For NCA cells (Panasonic) stay at 55% displayed SOC or lower. For NMC/NMC(A) (LG) stay at 60% displayed or lower. 50% is on the good side and causes about 50% of the calendar aging above 60%. The calendar aging...

The LG M50 cells are not high power cells. A lot of tests shows that they are not, neither for charging nor discharging. We can also see in tests that high charging power clearly causes a extra wear from quite low charging power so from that we can assume that Tesla need to limit the charging...

Well, yes. I guess he means keep it connected? Low SOC cutvthe calendar aging in half, which makes extra sense hot days. When deiving, these apply: (My MSP but from memory it was the same values for my 2021 M3P) Target for passive cooling of the batt is 40C. (Most certainly means using...

If it was for the past 6 years, it is not NMC. Before 2021 all batteries was NCA. (The Not worry part is correct :) )

Think average temperature. The SEI build up speed is set by SOC x Temp. So if you use the average cell temp you will get it right. This is LG M-50, from a report testing them. Probably not exactly the cell in Teslas but probably very close in these behaviours.

Tesla do not set up the cars properly from the factory. It is very probable that the car is out of spec even before mounting the spacer/shim. Correct Toe is very important to tyre wear so anyone need to check an S after delivery. Reducing the high negative camber is not a bad thing, but...

Up to 60% is okey with LG NMC(A). I would guess you would se about ~ 3-4% the first year. Or better. Equals 7-8% or so after 5 years. The above taken from tests with similar LG cells. I have collegues using the LG Pack with low SOC and they see very low degradation rates. Lower than I wrote...

Nope. Having sentry On, the car already is awake. If sentry was off and the car was sleeping, it will be awake for 20 minutes or less. It will draw ~ 75Wh, so 0.075kWh or around 0.1% on a 3/Y. I have logged a lot with scan my tesla/teslalogger. My M3P 2021 (HW3) used 220W during sentry...

There’s most certainly not any issue about a rapid degradation. But the BMS varies the estimate a bit up and down. And we can not safely compare a calculated range (displayed range/ SOC) as SOC is roundedwich means several km from the rounding error.

Does’nt cool here either. On the other hand perhaps it do not need any cooling Sub freezing :D Might be slight OT, but the iPhones was programmed to shut down when outside temperature limits. Apple problably did not think these cold get outside the lower limits so the the screen always stated...

Cabin overheat prot. Does’nt work?

Nothing very important. The older Pana NCA holds up good. Charges fast and deliver good power. LG seems to hold up very well. Charges slow and delivers less power.

Perform the enegy graf calculation instead of the miles thing. (Info about that early in hte thread)

2023 Y LR AWD = 330 miles, still? 2024 Y LR AWD = 304 still, or 310?

It is very probable that there is a large imbalance between the cells, causing the enetgy onboard to be lower than 100%, as the cell with the highest voltage set the charging stop when it reaches 100%. Charge to the set 100%. Let the car sleep overnight without sentry/cabin overheat etc. It...

One issue is to know the original (full) range. Just grabbing a number someone remembers might make it wrong. As there is a overhead before the range starts to drop you need to know that and apply the overhead to your calculation. We know the initial capacity of most Teslas. We can use the...

Thats about the same as where I get the calculation from 5 years at 90% at NC average temp. Driving more than average probably cause the average SOC to be slightly lower than a low mileage car that usually charhes to 80-90% So, 4.5% calendar aging or so the first year and ~ 10% in total, plus a...

The car always shows the EPA equivalent, even in WLTP-land. (WLTP is never displayed).

This is not really true. If it was very important to drive asap, Tesla would probably put that in the manual. IRL, the drive asap is a myth. 100% do age the battery in about the same rate as 80%. I guess ypur answer was aimed to Snos rap75? (NCA chemistry) The real difference is being at or...

Zero on screen means there ”should” be another 4.5% below that. 0% should be resonably safe from getting stranded, but the older the car get (BMS might be off) a little margin might be good).

Precisely as @AlanSubie4Life says, it doenst make much sense having lost very little in the first four years ans loosing another 10% the next year. Are you sure that you had 294 miles one year back? I would say that your battery started with ~ 77.8 kWh capacity and lost, perhaps slightly less...

I would calculate your probable degradation to around 10%, if you did charge the car as most people do. Not knowing the exact charging behaviour and the average cell temp, I used the most used charging behaviour and average temp for your area. That would put your car at around 70kWh, if you...

Canadian car, China built? All Y here in EU is ~531km (330mi) at full range, which includes the LG pack when it reaches the maximum. Initial range is often lower as the LG starts low sccording to the BMS.

Still the Panasonic 82kWh in this car or? We would expect around 76kWh after one year, if you normally charge to 70-90%. Its slower in the end of the year, so it looks about normal, a bot depending on the climate. My ex 2021 M3P are about 76.8kWh after 3.5 years and 80K km.

A full battery box on the Y with BYD Blade makes up ~ 60.5 kWh. Thats around 75-76% of what the LG/Panasonic li ion gives. So, with the BYD Blade and CATL LFP you will actually get a ”SR+” car. Combined with Dual motors, it would be a ”SR-”

Yes, same form factor (2170 /21700).

What SOC had it mostly been at ? What kind of climate? Parked outside or garage? In average temperatures we would expect around 10% (10-11%) calendar aging if the SOC was mostly 70-90%.

3 China only. Y Mix of China and Berlin. Same batteries on LR/P in both cases (LG NMC 78.8 kWh). S/X only made in US, so we get those.

You bet me on it :) 200mi@90% would be ~ 222 at 100% I see around 48.6kWh, doing a approx math…?

Use the energy graph, get these values on the same picture and post here, and we will do the math for you. The setting down right must be normal range, and the state of charge not too low (causes rounding errors), > 50% is good.

Just do it, and show it. Its very easy :) The energy graph is sourced from the BMS real data so this will take the uncertiness of third party app inconsistencies or doubts from these away. It is hard values, more non arguable than third party apps. For one thing, that car will need to loose...

Cyclic aging with partial discharging (not very big DoD) will have a appearent aging close to NIL. We did guess very early after the LFP’s was introduced that the BMS might not being able to track the capacity very well, and that the degradation we see could be a calculated from calendar aging...

Ahh, thought you asked for the stock setup. 10.5” square seems a bit wide in front. 9-10” inch if square I guess. ( My new low rolling resistance setup is 9” square with 245/40-20 but that setup is not for performance at all. Just to drive very efficient whichp it does very well)

The research has always known that 90% is safe from a calendar aging perspective. But then year at 80-90% daily charge will cause a calendar aging at about 15-16% or so (general value, did bit look into this cars place and average temperature etc). We know that the lithium battery industry...

The term[usable] is very miss-used and misunderstood so not valid in this case. Your picture probably shows the full capacity, normal “usable” was 74.3 kWh, from 77.8 kWh total. Initial capacity was 77.8kWh ( the EPA tests indicated delivering even more than that). You do not need to drive...

Care to take a picture and post?

My 23 MSP started a bit low on range and the BMS estimated capacity (slughtly below 96kWh) but one month in, the range was full and battery estimate 98.4 kWh (99.4 kWh full pack when new, so probably correct). Did you do any full charge lately?

I would charge when possible during the day, to keep the cycles in reasonable size. Also, charge late so the 80% is reached just before the morning shift starts. (I take it, it is not driven 24h/day, from the estimated miles after 10 years?)

Yes, you will be fine at 80%. I do not think ypu need to save for a new battery. (60% and lower would reduce the degradation but that do not seem like an option for you.)

We do not have that option either. Some kind of regulation probably, I do not know more than that.

Dendrites doesn’t form in this battery. Most probably a new myth forming. The 16V battery has 4 NMC cells in series. The built in BMS disconnects the 16V battery if the State of charge of the 16V battery goes below 10% or 13.8B or 3.46V in any of the four cells. After disconnection the...

21” arachnid is 9.5” front, 10.5” rear.

No, it is not bricked but undervoltage protected. The BMS need to see the correct voltage before it reconnects and charges.
