Model X P90DL degradation test after 100k km

[@Jer_Schmidt]

Thanks for another informative video! My 2013 S85 is at 6% degradation after 104k miles (167k km).

[@chengyuxi7144]

keep in mind that he uses super/fast charging a lot and multiple aggressive range test, AKA a battery abuser. 8% @100k km is pretty impressive given the abuse.

[@whathappenswhen4767]

from what i have understood is that charging your Tesla batt at very high speed, will degrade battery faster. also do not EVER let it get below 20% charge or youll get even more degradation. As well as, dont charge pass 80% or youll get even more degradation. Also outside temperature is another one. If you live in a very cold environment, ill make your batt weaker.

[@aaronmorton2072]

I’m glad you’re still doing good. I am a United States citizen, and your videos have always intrigued me from all the way over there. Keep doing you!

[@M1kke78]

Really waiting for the MCH's sound proofing episodes

[@RFjellstroem]

You make a really good showcasing of how much abuse the Tesla batteries can take. The 90 packs have the highest degradation chemistry of all the Teslas (that is why Tesla ditched it for the new 100 packs etc, and why 90-packs get supercharger power limit). So you have the highest degradation chemistry, charge mostly on DC fast charging (not necessarily that bad, but bad for 90-packs), pull trailer which hits you double (almost twice the cycling/km compared to typical, plus the extra degradation/cycle because of high temperature). I think your high-abuse 100.000 km is equal to about 250.000 km for typical use of new Tesla batteries (~170.000 typical km from cycling, +10-15% each for the chemistry, DC charging and high temperature). And still only 8% degradation. Quite impressive in my opinion.

[@kasmopaya2676]

Yes i think so too, at least 200.000 km worth of normal driving. Very good degradation for that. Hearing hat the 90 packs are so bad, i wish even more Optimus was ordered October 2016 for the 100kWh pack. A proper X needs a 100 pack. Part of the reason Optimus has to go now. The 100 pack can charge faster then 120kw. Poor Optimus, doomed from the beginning.

[@RFjellstroem]

@@kasmopaya2676 I believe (but am not sure) that it was Panasonics silicon mix in the anode that wasn't quite ready for primetime yet for the 90-pack (it is now from what I'm hearing). Since the silicon mix wasn't quite right and silicon changes volume dramatically when charged/discharged (could possibly be exacerbated by heat too like all chemical reactions) the 90-packs were subject to internal structure changes in the cells, particularly rapid ones when supercharging, that could damage the cell capacity. This is very possibly NOT a problem for 90-packs that are charged at home like most are, and they could have "Tesla-normal" (very good) degradation. But for use cases like Bjørns, the 90-packs have higher degradation than other Teslas (but still good compared to "EV-normal")

[@exio4]

the rate might be quite high because of the consumption - as you had to recharge a lot more to get these kilometers than most people

[@MarioDallaRiva]

Thanks, Bjorn. Maybe you could perform this test with your buddies' Model X with fewer Km's on the odometer(?) It would be interesting to see the results. I'm assuming they don't tow as you did of course.

[@Muturucgaming]

Bjorn, do the ventilated seats feel different on the new seats?

[@whuzzzup]

In addition to "degradation after x km" it would be interesting to have "degradation after x kWh charged via [supercharger|slowcharger]".

[@kbhasi]

3:04 I seriously thought he was going to cut to a montage. Then the song suddenly stopped.

[@kelvynbettridge]

These are very informative. Thanks Bjorn

[@MehmetcanKarahan]

There's something special about the Bjorn + Optimus Prime videos, going to really miss these.

[@Ulricdabe]

Hi, Same here on my S90D AP1 March '16 with 190K km (less than 10% SuC charge) V1 pack, 8,5% degradation. 398km (459 km new), that's life

[@bjornnyland]

The real degradation is 10.5 % because you forgot about the 2 % degradation that Tesla was hiding from you: kzbin.info/www/bejne/l6eqhnp8p7GljMU

[@ivanp104]

Hej Bjørn, Vilka däck hade du på när du gjorde testet? Hade du ventilation på under hela färden? När och varför fick du ditt batteri utbytt? Tack för mycket bra videos!

[@berttroubleyn3475]

I have a Model S with 100-pack. Deepest discharge I have ever done was 7 percent. Got 118 kW from the second I plugged it in. So the 100-pack seems more immune to this low SoC-throtling.

[@0ooTheMAXXoo0]

The battery has to be warm enough. The rate of charge will be slower if the battery is not warm enough.

[@bjornnyland]

This has nothing to do with not warm enough batteries.

[@benthecaptain7419]

Some more math for you. Your 100,000 km was done at 324Wh/km which is roughly x1.4 a normal 250Wh/km consumption (Fwiw we get about 230Wh/km in our '18 X75D) so you could say Optimus has the equivalent of +140,000km wear (almost 300,000km Total!). OR you could express this as Charge Cycles. Each cycle is 82kWh when new and now 75kWh. So this averages 78.5kWh. Your total kWh used is almost 64,500kWh and this battery is about half the indicated lifetime of that (I am assuming.) 32,250kWh used in total on this pack assuming the same use with both batteries. Based on an average of 78.5kWh per cycle you are about 410 cycles into the life. I think the batteries are supposed to give 1,000 cycles before they hit 80% (or was it 70%?) of original capacity. Which is -20% degradation. After 243,000km one would expect an 80% charge/range remaining. Of course if you can keep the charge between 20% and 70% at lower charging rates the wear can be reduced by about 1/4. So that's not too far from 1 million km!!!

Theres 2 or 3 Superchargers in the whole of Ireland. Also 1 Service Centre as well o.0

[@ashishpatel350]

How many times was It super charged in the batteries life? That's one of the main culprits for battery degradation

[@bjornnyland]

Lots

[@bradleycross5987]

Yes you are asking for the secret counter that Tesla keeps track of in the car/BMS. Of course you could track it manually too

[@Muturucgaming]

Can you do a test to see what happens if your car shuts off due to low battery charge while moving?

[@bjornnyland]

It doesn't because it has bricking protection.

[@SteveStonestream]

Hello Mr. Nyland, I plan a roadtrip to Norway and maybe Sweden with my Model S. Can you recommend some nice places to visit? And at which points i should pay attention ?

[@roomempty343]

you will pay big attention to ze norge police for their insane low speed limits, hidden signs where they sitting near traps hunting on fat tourist prey.

[@CoolSilver]

At least your BMS was calibrated and your 12 V battery was good. 8% I guess is high but they say the first year you lose the most. I need to test my car like this being just under 27k km. From what stats I've gotten I'm still less than 1% degradation

[@brk00034]

Hı, did you replace battery pack until this km ?

[@hwjkim]

do you litsen to Twice? wow...how did you know them ;;

[@mojohn2154]

What exactly does he mean by "the infamous power limit 200 kW"? Does it mean that when you are low on charge your maximum power output is limited?

[@antonkeule]

Honza Mokry yes

[@mojohn2154]

​@@antonkeule 200 kW still doesn't sound too bad :D

[@antonkeule]

Honza Mokry the Maximum is (i believe) ~ 400 kw. Yeah sure, still impressive and only in the low SoC.

[@bjornnyland]

+Honza Mokry yes

[@andrew7455]

Doesn't Tesla give the information about current battery degradation like the Nissan Leaf does?

[@RubenKelevra]

They just give an estimation on the available km for the given state of charge.

[@andrew7455]

@@RubenKelevra, then, I assume the only correct way to check the battery degradation is to measure the number of kilowatts that car receives from the wall.

[@awo1fman]

@@andrew7455 No, the only correct way is the way Bjørn does it, to see how much you get out of it. What you put in from the wall includes several kinds of charging losses that have nothing to do with the battery.

[@bjornnyland]

+Andrew Obviously not

[@RubenKelevra]

@@andrew7455 as Bjørn pointed out in his video (did you even watched it?) older batteries have higher internal resistances, leading to higher charging loss for the same amount of capacity. But you don't want to measure the efficiency, but the capacity. So you have look how much you can take out of the battery, when it's degraded. That's why he's doing test rides.

[@alexandreesquenet3736]

Can you read the SOH with an OBD, like for the Kona?

[@e-mobilitydrivingsolutions4449]

Isn't the estimated range calculated by using last driving profiles? I would use the kWh total of the Battery pack as the value to define the condition. The range will change from day to day.

[@bjornnyland]

[@lyckokaka]

Thumbs up for the Twice song at 3:07!

[@stighaaland5357]

Not bad at all. I saw a model s on the Like Tesla channel which only had a 3% degradation after 5 years, and 120k kilometres. They only used what the screen tells them what is available. But this person never supercharged the car in 5 years.

[@bjornnyland]

They didn't know about the 2 % that Tesla was hiding. So in reality it was 5 % degradation. kzbin.info/www/bejne/l6eqhnp8p7GljMU

[@Larsema1]

The new batteries are better. On the other hand, they will soon be charged much faster.. up to 3 times faster. I wonder how fast they will degrade then. Or after how many times the charging speed will be restricted. Guess I better keep on watching the coming episodes :)

[@sadlogic]

Since last charge km times Wh/km doesnt add up to the KWh. Strange.

[@bjornnyland]

You did a classic round-off error. Try the other way: 71.1 kWh / 329.8 km = 215.585 Wh/km which rounds up to 216 Wh/km

[@sadlogic]

[@AGUADILLAN1]

Is this degradation on the new battery pack you got when the other one went bad?

[@TBasianeyes]

yes

[@mwojciak]

Can you ask for battery replacement if degradation is high? Lets say 10% after 100kkm.

[@DavideMoriello]

10% is still not high. I think 18% is high

[@janaebert3059]

This would completely destroy the ecological aspect of the car.

[@mwojciak]

@@janaebert3059 so you say that everyone should stick with original battery forever, becouse of ecological aspect? ;)

[@dschledermann]

10% is not that much. Certainly not something you are going to notice in daily use. The degradation is likely to level off after 10%, so it has to drive around 300.000 km before reaching 18%.

[@awo1fman]

@@janaebert3059 Nope. Used car battery packs are disassembled and turned into home batteries and other "second life" uses. Cells that are truly dead are recycled.

[@robertfader3046]

As a person that drives Teslas everyday for a living this is a realistic for most peoples driving habits but is a false representation of how the battery will degrade these vehicles it's all how you drive it and maintain it in this cause this would be realistic for someone who puts extreme stress on the vehicle and in most cases if he was to actually set autopilot to the speed limit like he is supposed to even with pulling a trailer he wouldn't be seeing any degredation and this vehicle has obviously been run down to nothing many times and realistically if you run a gas car dry a few time if your lucky you will only need to replace the low pressure fuel pump it's simple the vehicle is smart enough to equalize the cells and slowly charge to lengthen the life of the battery his next test should be to compare the etron and see how long it's battery can last under the same extreme conditions
