4% degradation on my 70D after 5 years and 200K kilometers. Very impressiv car only one doorhandle and schocks rear fix .👍👍

I wish this information is more readily available from Tesla. It would be nice to be able to see the energy usage due to speed, hills, head wind, a/c, heater, etc.

I have a 2014 Model S 60 with 60,000km in Japan .I AC charge 10 or 8 amps @100v on 50 Hz all the time because there are no Tesla chargers near. I do DC charge with the chademo adapter ,but it's rare. If you like I can give you the numbers off scan my Tesla.

Using your math, my 2020 Model Y has about 3% degradation (304 vs 316) in 81xx miles. 70% has been charged on AC. Another great video with great info.

I thought you bought back Optimus Prime! LOL

People have unique perspectives and each are valuable, thank you for yours Bjorn. Very insightful 👏

Yet, another, reason why we went for Tesla...the confidence that you leave the car to manage battery health and longevity, on its own. Just plug it in when you get back home (or arrive at destination), and let it do its thing.

Thanks for posting, 3% is impressive after 4 years and 100,000 miles. I’ve heard predictions of 500,000 miles as the effective life of the battery pack, and this seems to confirm it.

The cell has been through around 370 charge cycles. Degradation is around 3%. If it remains linear, after 2000 cycles, we're looking at approximately 16%. Definitely better than expected 20% but still in line with expected results for the battery cells used.

One day a company will sell a “CarFax” on EV’s where it shows battery degradation. It’s only a matter of time.

Thank for the video! A white board would help a lot with the explanation.

Please make video for Hundai ioniq degradation (28 kwh, 38kwh). Thanks before. And bonus video for nissan leaf XD

Beautiful Model X! Thank you so much, Bjørn

I have 92.2 kwh in nominal full pack after 55 kkm in the same car. When it was new typcal range was 450 km.

I like this in-depth analysis, although it can be a bit confusing in its field definitions. My Apple laptop would show detailed system parameters, so it is a pity that EVs don’t provide access to it through the dash.

Thoughts on the story of the Model S than has done 400,000km and only 10% degradation?

@Bjorn Do we know charging habbits? Like how often was it charged to 100% and what was typical daily charge?

Thank you for your effort and help with these videos / tutorials. We live in Norway as well and have currently TMS 2018 mod. but we would like to upgrade to TMX 100d.

Would be nice to refresh testing on battery drain when the car is switched off maybe on the newest Model 3s?

Hi Bjørn! Have you tested phantom drain on Tesla when you use Power Off feature in the Safety & Security. I was thinking if the car still uses any energy. You could test this in your garage.

Not bad at all for 4 years

My M3LR has 0 kwh dc charging and I usually charge with 4kw ac max. Curious if degradation is lower and by how much

My Subaru Forester is 22 years old now, still going strong. Yes, not an option in Europe, but in Africa, where I stay, electric cars won't be an option any time soon am afraid...

Thank you, Bjorn!!!!

VERY interesting! I think you are right to use the specification battery size rather than the actual size for the degradation test. The customer bought the car based on its specified range which will not include this "Extra" capacity! One thing you might like to report on is the one-year, five-year, battery degradation for all the cars you test?? I realize this might be a pain in the ass, but will be a very useful piece of information for people who would like to buy second-hand EV's or intend to keep the car for its full life! I suspect that this is another area that tesla is continually improving which adds value to their cars! Significant battery degradation, particularly for DC Fast-charge users, is something that all EV owners should be aware of and take into account when buying an EV!

It would appear an ev should last much longer then a fossil. If batteries can run 500,000 miles or more. Not many fossils top that number. An ev if kept in good shape could last a person a lifetime.

Hi Bjørn, I'm planning to buy my first EV soon, considering Polestar 2. Is there any chance for summer range tests or battery degradation test in one-year old P2?

Can you do degradation test on the Audi Etron 50?

I got my MS LR (Raven) in sept of 2019. It now has 85.000 km on the odo and I use Superchargers 99% of the time and always charge to 90%. Since januari 2020 I write down regularly what the car says the range is with 90% state of charge : always around 506 km and now and then up to 521 km again. So the 3,5 % degradation isn't even degradation at all, because it's compared with brand new and some degradation during the first half hear is normal. Recently I got 412,5 km from 90% to 2% doing my job (all types of roads, 40 stops). So I don't see any degradation so far despite always Supercharging. I'm planning to drive my car until the end en will always use Superchargers for at least another 2 years. It's for free, it's only 5 km away from home and I have only 3 kW at home. When my new house is built, I want to be able to charge overnight and will habe solar panels. When brand new 100 % said 578 km and in March of 2020 it said 560 km, so also 3% degradation after 6 months. Since then I never charged to 100% again but maybe I will in 2 weeks whan I'm going in holidays. Maybe I'm lucky, maybe always using SuC is not that bad, time will tell... In the meantime I save o lot of money and if I lose some range in the long run, it's not a disaster. Charging rate btw is still normal (up to 144 kW).

I have a 2018 tesla model x with 217000 km. Using it a lot with caravan. Want to look at the degradation?

Regenerated charge is much bigger than DC charge :)

Hur många EV har topp buffer så de riskfritt kan laddas fullt varje gång? När du laddar fullt, hur längre låter du då MX:en i detta fall stå med full laddat batteri? När tar batteriet skada av detta?

Would charging from a 120v prolong the batter compared to charging at 240

It says it regenerated 5761 kWh. It this true? It would mean that around 28.000 km has been driven on regenerated power 🤯 more than 1/4 of the odometer…

2018 X 100d 10,000 miles from new shows 90.5 nonamal full pack ?

will you test the dacia spring?

I think the BMS should be use to check the degradation, so 6.7% in this case. Substracting buffers and internal losses just add misleading complexity and dependencies on the measurements. I belive this is how Tesla will claim if the battery is still in warranty levels that is what it matters 😅

How many charge cycles has it done?

Ac charging helps :)

Am I the only one who is missing the original Degradation tests?

Can anyone recomand me which Tesla model s variant is most efficent and longest range? Is it raven or ??

Any sign of the Kia EV6 yet to test drive.

About 7% on my Model 3 after 3 years and 66,845.

I don't understand why you use 90 kWh as the "specification" for what is advertised as a 100 kWh battery. You used 90 as the spec to calculate the degradation as only 3%. Why not use 100? Where do you get the figure of 90 as the spec? Maybe I missed something in your explanation....

Bjorn, if it’s a 100D, shouldn’t the specification be 100 kWh? I didn’t understand why you divided by 90. Am I missing something?

My favourite car😎

How much do you charge the battery up to on a normal day to day basis ?

So how come the model name is 100D and it has got like 93Kw battery from new?

I have an identical car (X100D, 2017, 98'660 Km). DC Charge 3'091 KWh, AC Charge 21'619 Kwh. Nominal Full Pack today: 89.1 KWh (versus versus the 93.7 KWh above). Always charged max. 80%. Careful driving (summer/winter mix): 21.5 KWh/100 km. Summary: NOT ALL TESLAS ARE THAT GOOD! If you believe in FSD, buy a Tesla. If you lost that faith (like me), there are plenty of other EVs out there today. The absolutely only Tesla-USP: Supercharger network. NB: FSD. No Tesla will ever drive autonomously. I would be happy if the wipers would work automatically.

A lot of calculation, but "Usable remaining: 88.5" Its already there on the tester.

Do Teslas not have a top buffer?

If you drive the car for ~400km to emptying the batterie and calculate the battery capacity based on the consumption per driven Km as showed in the cars Info computer… what’s with the regeneration? Every de acceleration and breaking will virtually add battery capacity and give a wrongful picture of the level of degradation !? I’ve been thinking that true over and over and even in my EQC with induction motors it is not really possible to set the car in “neutral” for every breaking to only use the hydraulic breaks and avoid an misleading picture of the cars consumption including the regeneration

It’s not unusual to have a car that’s mostly AC charged, according to market research. Most cars are mostly AC charged. Specifically, in North America’s 90% of charging is destination charging, and that’s overwhelmingly AC. You’re an outlier, Bjorn! :-D

What did you mean by 'compared to spec'? You wrote 90kWh as spec for this 100D. Why did you choose this amount?

Not bad a all, but Bjørn to many numbers and very confusing in the beginning.

Only 2 years in and 30000km. I have 431km on a full 100% charge. It used to be 460km on a full charge when new. Thus 6.3% degradation.

The batteries are good until they go into the last part/stage of their lifecycle. From then on, in no time they are gone. *That part would be interesting to see.

Why don't you start from 100 kwh? For me degradation is 6,3 %

omg why does it show "kWh" on some lines and "kWH" on others... 🤢 Disappointing for an app aimed at data nerds 😒
