Yes, it should be lifetime. You also have a very small amount of DC charging 31.9 kwh.

No, your actual capacity of 55.3 kWh includes the buffer. So If your conversion constant is 286 Wh/mi ( it could be 285 or 287 also), then your degradation would be 55.3/.286/208 = about 7%. That equals what you calculated and is excellent for your battery at this stage. It looks like your...

Thanks for sharing the data. Also, it's good that you showed the ALL tab since it shows the complete data set. Your battery certainly appears to be in good shape, at least capacity wise. You have 55.3 kWh nominal full pack which represents the total battery capacity. As a comparison, my...

Just screen shot pictures will work for most things you need to understand.

Please post your data and there are plenty of people here glad to help you interpret it!

What is your llifetime Wh/mi? I am at 292 Wh/mi lifetime after about 170k total miles. If I am driving moderate speed on the freeway, I get around 265 Wh/mi.

What version of SMT are you using? I didn't know you could get the CAC values from the older cars. Where did you get the parts (cable and adapter for SMT)?

Your numbers look pretty accurate. I would expect SMT to match closely to the TeslaMate values you have shown, although what TeslaMate calls usable is not really usable, unless you include the 4.0 kWh buffer. In SMT, your 61.5 kWh equivalent value is called Nominal Full Pack. My car is the...

There is another easy way to calculate the constant for your car without requiring use of SMT. If you have an app like Tessie or possibly TeslaMate, they usually keep track of your charge data. If you have a pretty good history of your charge data from the app all you need to do is take total...

I remember when Jason posted these numbers and there wasn't much SMT data at that time to compare to. But I was suspicious of those numbers from Jason because they didn't match well with what I saw from my own car that had a 4.0 kWh buffer when I bought it new in 2015, and also had a full...

The battery does look good as far as degradation goes. But it still leaves the question of how the display shows 385 miles at 100%, when the new rated range number was 370 miles, unless it really is a long range +. I agree it is a little bit of a red flag that the owner got rid of the car after...

You're looking at the right place, so it doesn't appear to have the option to change the display to ideal miles. Did you find out any more information? You can use the energy screen method to calculate the approximate capacity of the battery to help determine degradation if you are still...

My car (70D) I bought new in 2015, and it always had a 4.0 kWh buffer. I am not sure where the idea of a lower buffer of 2.4 came from but I think maybe the 60 kWh cars did have a smaller buffer. But the 70 cars always had 4.0 kWh. Is your battery the original? That is very little...

I am not sure how TeslaMate derives those capacity numbers but they are incorrect. The 70D started at 68.88 kWh nominal full pack with a 4.0 kWh buffer. So usable new was 64.88 kWh. My verification of this is from TM-Spy which is CANBUS data, the same as SMT. However, rated range is calculated...

Actually, I don't think your range numbers sound that bad if you consider everything. Did the 2020 also come with 19" rims? Usually the rating of 402 would be with the smaller wheels, so with the 21" you would expect less than that. And if you average efficiency is 330 Wh/mi, you are doing...

There is an easy way to get a very good estimate of your battery kWh. It is a sticky thread in the M3 battery and charging forum. Maybe that is how you got your estimate, but if not, you could check that out.

It seems like if it was a mistake or bug they would have fixed it right away. If your window sticker says 359 that is most likely correct. Maybe Tesla just made the displayed miles more in line with what typical owners would experience driving. I don't think Tesla has to make the display...

The old Teslas originally used a fixed buffer of 4 kWh. Now I believe they use a value that can vary with total battery capacity. I think it is now 4.5 % of nominal full pack. That would be about 4.36 kWh for your 96.9 kWh battery. What is your CANBUS buffer reading? I know this is not...

Any updates on this situation? According to Tesla, you have about 3.3% degradation to your battery, which of course you know is BS. I think there is a health check feature in your car that you can use to check your battery. I'm curious if you have tried that to see what it says.

Did you get a reman or new pack? Because 230 miles was the full rated miles for an original S70 when new. So whatever you got, that's pretty good.

Did you have any warning signs prior to your failure? How much degradation did your original battery have prior to the failure? What did Tesla guarantee for capacity on the refurb pack?

I agree with you here. I should have been more precise and said they can adjust the displayed range.

It's not just the 2024 model Y that is showing less than the "advertised" EPA estimate. People are claiming that the 2024 Model S Plaid is showing only 347 miles at 100% charge with an advertised range estimate of 359 miles. When Tesla was asked about this they said "it is normal to lose...

Have you asked Tesla about this? They should have some kind of response for such a big discrepancy.

I think the bottom line is that CAC is useful for comparing cell to cell, but not the best method for determining nominal capacity for reasons like you mentioned.

New nominal full pack for an S 70 was 68.88 kWh. So what is being labelled as Usable (new) and Usable (now) in you chart is incorrect. Those chart values are the same as SMT nominal full pack values. The actual usable does not include the buffer so those readings should be 4.0 kWh less than...

I think this represents how most people feel about the situation here. I came extremely close to purchasing a service plan since my car was a perfect candidate for one, and I really liked the idea of having the BMD. But I'm just very lucky I didn't go through with it. I know now that if I...

Oh yeah, I totally get that! But once you were home and safely plugged in, you could have taken SMT readings correct? I think you said have SMT capability.

I don't know what the blue snowflake does to the numbers since I never see cold temperatures like that. You were showing 0% on the battery, so I am wondering what it showed for miles if you switched it to miles? The graph showed -1.2% which is about -3.7 miles for you. It would have been...

According to the Tesla website, the plaid with 21" has an EPA range of 320 miles which equals about 515 km. Do you know what standard they use in your car to get 560 km (348 miles) for full range? That's a pretty big difference. Is that a realistic value under typical driving conditions?

Your max full pack was 98.4 and currently is at 97.5. How much change have you seen in the corresponding full rated range in miles for those two cases? Do you still see the full rated range?

They must have made some of the Gen 1 cables better than others. I have used mine every day for over 8 years and always charge at 40 amps. I can barely feel it warm at the end of charging. Maybe I just got lucky in that regard.

Your degradation over time looks pretty good. However, your mileage of 276 is not consistent with EPA rating of 240 mileage when new, as the post above states. Also, Europe had their own system (NEDC?) which was different than used in the U.S. If you want to compare your car's absolute...

That's less than 2% degradation in 3 years! Are you trying to challenge @KenC?

News must travel slow in Portugal.

For the MS cars, SMT calculates SOC as (Nominal Remain - Buffer)/(Nominal Full - Buffer). For this case that would be (53.8 -4.0)/(73.7 - 4.0). This equals 71.449 or 71.4, which matches the SMT readout. However, for SMT SOC to match the car's display, the proper equation should be: (Ideal...

Other than the fixed buffer size (4.0 kWh), the old MS cars calculate the SOC % and full pack value the same as the M3 does. Unless they did something different for the performance models, which I don't think so but I guess it's possible.

The 75D was rated at 259 miles EPA when new. So 80% should have been around 207 miles instead of 226. If it is now at 185 miles at 80%, that is about 11% battery degradation from new EPA value, which is pretty normal.

The BMS determines the battery kWh capacity and it is given as the Nominal Full Pack value from the CAN bus reading. The energy screen calculation gives you the same value, although because it contains uncertainty errors, it may be slightly different than the SMT reading. So the energy screen...

Why is your HV battery showing 2.68 kW? That seems like a lot if your car is just sitting there. Your DC-DC input power is much lower at 320 W.

If you have a Standard Range Plus then you should have shown about 240 miles for a 100% charge when the car was new. Is that what you saw? If you only showed about 220 miles when the car was new, you have a Standard Range where a certain percentage of your battery capacity was locked out, and...

Are those fairly recent events? I'm just wondering if you used to be able to get down close to zero in previous years, and now for some reason it won't do it.

Besides what others have said here, you show you were only charged to 20%. Many people have shown their cars to have large cell imbalances at low SOC, but it improves significantly at higher SOC. I don't know what exactly that means because my car shows about the same cell imbalance regardless...

I wouldn't say using % is better, but rather a personal choice. I actually prefer using miles because it gives me more information. But I can see the argument for using %, and I think most people probably do that. I wish they would give the option to display both at the same time, and then I...

My 2015 70D is also showing about 20-25 mv balance, from an original of about 4 mv. My rated range is now down to about 195 miles, with about 162k miles on the car.

You would have to continue driving after the car reaches 0% SOC to reach the EPA miles, and even then there is no guarantee you would get all the EPA miles if you continue to drive below 0%. There are many cases of people being stranded on the side of the road for trying this. So yes, it is...

He might have been talking about the energy screen, in which case the screen is exaggerating your available miles. Because if you are driving at EPA energy efficiency, the screen will tell you that you will achieve rated miles, when in fact, you are getting 95.5% of that. Whether that...

You are mixing up two different things here. The indicated range of 265 and 245 you mention is the rated range for the car and is the number displayed next to the battery icon. These values correspond to the amount of energy available in the battery as determined by the BMS, which is normally...

What data will you access to, and is it anything different than what the owner can already observe?

The full rated value is calculated but I'm not sure how SMT does it. I think your nominal full pack is right on the cusp of the degradation threshold of 76 kWh. Do you remember the maximum NFP you have seen? @AlanSubie4Life could verify if that is the case. If your rated constant is 245...
