Isabel scores high on the cuteness factor 💕
With a BMW I3s, 2019, 45000 KM, still above 120Ah battery capacity . Just an amazing car. Thanks for the test!
Bjorn - appreciate all you do - take care of the family first. ABC - Always Be Caring!
I have a 94ah 09/2016 with 147850km. I can also confirm the data.
At 100tkm I still had 98% according to the aviloo test
I would like to continue driving it until 200tkm and then drive another bev.
I have owned the I3 since 03/2019 and am mega satisfied.
According to the battery spec sheet the 94 Ah Samsung SDI cells are rated for 4600 cycles to 80% capacity, or roughly 920000km assuming 200km on a charge, so that definitely seems to line up with that.
You’re a good Dad.
Thanks for doing these tests of older evs. This is the info people really need.
Love to see your daughter! She's very well behaved too.
Colics are true nightmares not only for the child but for parents as well. We went through this with our son and I'm so glad it's over
Any techniques you found useful? My newborn has colic.
No Worries Björn, bring your Kids every Time :D
ABC = Always Bring Child
@@bjornnyland Have you updated this to google sheeet? Where did you get 30,3kWh. I found only that when i3 94ah have been new it had 29,5kWh usable.
Thanks Bjorn I really appreciate this car!!!
Samsung SDI prismatic batteries for the win.
6000 cycles to 20% degradation, 30 year pack life. Samsung does not show a pack "degradation by age" chart.
At 6000 cycles to 20% degradation the mileage would be:
1st Gen 110km x 6000 = 660,000 km for the 21.40 kWh pack
2nd Gen 166km x 6000 = 996,000 km for the 33.77 kWh pack
Danke! Great informative video!
Danke Schön :)
That's pretty good for a small battery, the smaller the battery the more cycles or more deep cycles vs the same amount driven in a car with a larger battery. We have 53k miles (85,000 km) now on our Ioniq 5 and when I checked it at 50k it only has lost 0.9% capacity. BMS was still reporting 100% SOH but it's actually lost about 0.5kwh when charged to 100% then you read the remaining energy. The low loss is likely because we most always charge at home and only to 80%. We only need to charge to 100% or fast charge when going on trips.
From some lg document's i've read, the smaller the energy density in the cells, the better the cycle count they can achieve. Basically, even though a smaller battery has to do more cycles it degrades less. A bigger battery needs to do less cycles but it degrades more per cycle. They basically cancel eachother out.
Out 2019 i3 120Ah is down to 96,6% @58.000 km. In theory it will reach 70% @ 500.000 km. It is rapid-charged quite often.
Batteries often lose a couple percent early on in their life before stablizing at a set rate of degradation. I'd say 500000 km is *very* conservative, especially considering the earlier 94 Ah Samsung SDI batteries were rated for 4600 cycles, or roughly 920000 km to 80% capacity assuming 200 km per cycle.
It'll probably last even more than that.
I like you, your family and your videos with family. It feels that you are littlebit my friend who dont know my family 😄
Alles gut ❤
7 years old BMW better then new VW ID...
Would you recommend buying a good i3 on the used market for small trips, in denmark? They are quite cheap
Very important test. Could you include a column for cell chemistry?
Don't worry about Axel, our second born was very demanding too... It ended in elementary school
Alles gut!
I have a question: is it possible that not linear scale of percentage is due to degradation of battery?
Great Car. I just testet our 150.000km Kia eSoul 64kwh ONLY 2% Degradation with 80% DC charging. Test with Aviloo. Crazy! Cant beliebe it😅
Another great video! I love my ⚡️🔋BMW i3s 120ah 💯🤩 for 60000km kilometers until today. Looking forward to the next 60000km 😅
No degradation tests for the stellantis family of cars? Peugeot, Citroen; Opel, DS, Jeep?
It might be good to include the chemistry of the battery in the table, in this case it is probably chemistry NMC333 (according to ev database).
It has 94Ah NMC111 (Also known as NMC333) battery modules rated for 4600 charge/discharge cycles to 80% capacity.
Assuming that you go 200km on an average cycle, which you easily do if you don't do lots of highway driving, that would mean it is rated for 920 000 km until 80% capacity, and is likely why degradation is so low.
I believe low degradation levels like these will be getting more and more common now as batteries advance over time, will be interesting to see how these hold up in 25 years time from now.
@@swecreations In my opinion, newer batteries with reduced cobalt content (NMC811) degrade faster than older NMC333 batteries such as this one.
Can degradation be tested by (almost) emptying the battery and then seeing how much energy it uses to fill up?
If there's no log for the number of cycles, how can Bjorn know how many cycles this car has had? We can't use distance travelled because someone could be doing lots of small charges which degrades the battery less than someone going from 0-100%
TeslaBjørn! Be aware of when you charge to 100% on the i3 on the home charger and you let the car decide, when it is full, you get about 2-3% more juice on the battery, than if you stop, when it says 100 have been reached.
Can you explain this? 100% is 100%. What do you mean by 2-3% more?
@@pilotandthecity8527 I found out much to my surprise, that if I when using Monta’s Smartcharge system, did set the SoC of the car too low ( first time because I was too lazy to open the BMW app to check, then the charger would continue to charge until the car shut off charging. In the app it paused the charging session, and I would then go in the app, and manually stop the charging session.
I better explain how the system works here in Denmark. Normally every kWh used is added a tax of 0,946 Dkr or 13,9 US cents. But with a home charger and a subscription plan with an electricity provider you get this tax refunded for electricity charged onto your EV. I use a company, NRGi for both my normal electricity usage and for charging my BMW i3S. And they use Monta’s system and app to run the charger. The App has Smart charge allowing you to charge within the cheapest period with in a time slot you define and to a SoC you define by setting current state of charge and the required SoC and the end and you define, the time the car has to be ready. This means I often is able to fully charge my car up to 100% for less than a dollar.
What I experienced after having set the smart charging to a too low starting point and the car itself had to stop the charging, was that I drove much longer on the first 1% from 100 down to 99%.
I asked people in a Danish BMW i3 forum on Facebook if they had noticed the same. One guy had sat in his car and watched the car continue charging from 95% to 100% and until it ended the charging. When reaching 100 the car had received 12,4 kWh, but the charger did not stop until 12 minutes later having delivered 13,3 KWh. So it actually charged another 0,9 kWh onto the battery, before the car turns off the charging session. So on the first 1% you get much farther, than normal!
On the flip side I noticed, when I DC charge to 90% and then go, then the first 2 % has left the battery almost before I get out of the parking lot.
@@pilotandthecity8527If you let the car charge until it stops it will continue roughly 12 minutes after it reaches 100% on the meter. I have an example where the car (120 Ah battery pack) when the car reached 100.% having received 12,4 kWh continued to charge for 12 minutes charging to 13,3 kWh so you get an extra 0,9 kWh. At 155 w/km you get 5,8 km extra on the first 1% on the meter.
During those final minutes of charging it will be balancing the battery cells.
@@tonrotterdamI will not claim you are wrong. But the charger continues to pump in juice after the 100% mark is reached on the cars battery indicator. 0,9 KWh to be exact is added.
Regardless what we call it, it is my experience that I go much further on the first 1%, than I usually do.
On the flip side of it, when I charge with DC to 90% then the first 2% bleeds of in a few hundred meters rather than kilometers. I think that is due to balancing the cells.
On the degradation per cycle, I guess the decimal point does not match the "%" unit. Should be 0.68%/cycle.
Bjørn's units are %/1000 cycles, IIRC. The 1000 is not shown due to the narrow column width.
I wonder if the Mini Cooper SE would be the same since it has the same battery?
They may have the same Samsung cells, but I know that the Mini Cooper battery is shaped like the letter T, may affect cooling and increased degradation.
@@andersantonsen9524These Samsung SDI prismatic cells are rated for 4600 cycles to 80% and incredibly stable, they will have very good degradation performance regardless.
Have you tried lavender to help baby sleep
Hej Björn! Vår dotter hade mjölkprotein intolerans. När wifie slutade med mejeriprodukter så slutade min dotter gråta. Kan vara värt att testa!
Han sa i en tidigare video att hans fru har slutat dricka mjölk. Det är förmodligen så att det bara är att härda ut tills tarmarna mognar. :(
Thank you for the tip :)
@@bjornnylandSnakk med de på helsestasjonen om allergitest(ikke legen, de mente at det var for tidlig), vi testet vår 6mnd sønn og fant ut at han hadde melk,egg,fisk,erter allergi. Når mor sluttet med disse produktene ble alt mye bedre med sønnen.
One child seems easy. With the second one it is two against two, and feels like triple the job. All the best for you and wife!
As my friend always saying I buy car only from the company that have high quality standards for materials they use. Looks like BMW is one of them .
Maybe I’m too st00pid to understand the calculation, but I am always getting values for degr/cycles which are off by 1 decimal 😭
8:06 can you test model 3 LFP 55KWH or atlest 2year old / 50K on odometer and compare it to to raven or M3 LR how ironphosphate battery degradate with others!!
And then....
Wondeing the degradation in a car with LFP when charged to 80% vs 100%
❤❤❤
That’s a pretty good number, can you hook with some computer and check again
Why? I already checked service menu and it corresponds with my test. If you hook it up to the computer you will find the exact same value as what the service menu reported.
@@bjornnyland great then …
@@GreenDriveIndiaHis testing lines up well with the rated specifications of the battery cells used, which is 4600 cycles to 80% battery capacity.
I think Isobel needs a bigger seat.

I just bought 2017 BMW i3 33kWh+rex. It is my therapy EV. I have lost my mind with Tesla Model Y because four heatpumps have broke. I have lost faith to the car and I need BMW therapy. Tesla is shiiiiit.
I totally get it, except the REX-part. Or is it some sort of Shakti mat style therapy where you also have to suffer a bit? 😂
@@bowbinger I think littlebit of suffering is part of the therapy. Its because its suffering all the time with Tesla in winter. You have to think day and night when my heatpump will broke next time. In trueth on my area isnt too much fast chargers and Tesla offers enough range but i3 without rex does not fit here😪
@@Seikkailusankar1 I wish you warm and safe travels and many trouble free miles before the first check engine light, or oil service notification 😉
@@bowbinger Thanks! Fingers crossed for trouble free driving. I have been into motorcycling and building them all my life. i hope i can do well with these skills with rex. BMW motorcycles are known very reliable but this is scooter engine 😁
@@Seikkailusankar1 It sounds like a single „Monday Car“ case. A few cars were affected by dust contamination of some AC pipes (or tubes), because a supplier forgot to protect the pipes for transport. When the AC has to be replaced, the AC pipes and AC pumps should at least be flushed or replaced.
did this some year ago. need a baby cam hehe
What about kindergarden? It is healthy for the children AND parents :)
Isabel is starting on 1 August.
