    Just give an AVILOO degradation test device to the taxi company, let them run the test and collect the device two days later again. They will be happy because they have information about the degradation, you are happy because you have more data on your hands with not too much work, and we are happy because we can watch more degredation videos.

    Very interesting! EQC is an underappreciated car. What would also be interesting is degredation per kilometre driven. From an engineering standpoint it's cool to see it per cycle, but as a customer, all you're usually really interested in is the effect of kilometres, IMO.

My wife and I also have Volvo xc90 T8 hybrid since end of 2020, which is better in every way and basically the same price. The most underwhelming aspects of the EQC are the lack of practicality , less than zero off road capability (car bottoms out over minor speed humps, didn’t happen on my BMW 530e which I owned immediately previously to the EQC), and the interior design/ feel/ quality which is for all intents and purposes, lifted straight out of a 2020 c class.

Just a side note as an 2018Ioniq driver with 198k km behind me the degradation really shows the most in the lower % where the "guestemate" becomes more hectic. Imo the real degradation is exactly in these last 20~25% where the charge just vaporize in thin air.

    Once this car turns 6-7+ years old, then i want to see how degrated the batteries are.

    Coming up to 4 years with the Kia e-Niro, 73,000 km and no discernible loss of range. My MO for charging is to 80% once a week or when we get in the 25% - 30% range unless I am doing a long journey or a remember to do what the manual says and take it to 100% once a month. Have only ever had the car below 10% once. They say that an NMC pouch cell battery like mine will be done in 1,000 cycles but the data suggests that partial charging brings that up to 2,000 to 3,000 cycles before the owner will notice a drop in range. So far this year my average added % on each plugin is 32%....so about 20 kWh of the 64 KWh battery. Sorry, but I’m a bit of a stats nerd. Given my winter/summer average efficiency of 14.5 kWh/100 km that’s 138 km of range added every time I plug in. So doing that 2,500 times gives me 342,500 km...before the car gets below 80% of its original range. At my age, doing an average of 20,000 km a year I am not too worried.

    First year it charged at 7kwh (32 amp single phase) charger and now (Due to moving and not having that charger) I use the granny charger that does maybe 2kwh.
    The car doesn't give me any information at all, but I can share with you my most recent trip to work
    Morning temp was ~10c
    I started the day with 88% reported soc
    drove 89.6 km to office.
    Afternoon was ~22c
    drove 88.4km back home.
    Total distance: 178 km
    end of trip soc was 27%
    Assuming total usable capacity of 42kwh, I used 25.62kwh which gave me an economy figure of 14.4 kwh/100km
    That is the best case scenario, because ~60% was in traffic moving slowly and the rest was at 90km/h (speedometer reading)

    What happens when your battery degraded too much for your needs? Do you recycle the whole car so the "bad" battery can be used for stationary purposes? Or do you replace the battery for a lot of money? Given it's out of warranty. I don't understand how this is more gentle to the environment than an ICE. You don't replace the engine every 100.000 - 200.000 km and even if you would, it's not as dirty to produce than a battery. Apart from the exhaust pollution, I really can't see the disadvantage of ICE. Can someone enlighten me please?

    After 4 years they’ll accumulate over 1million kilometres, from here they will continue running for another 1-2 years before being exported to Saudi Arabia where they’ll continue running presumably since people actually buy them

    Thanks again for an interesting video, but I'd like to make two comments. Less than quarter million km and "high mileage" do not rhyme on Mercedes. And did you really check the trip computer error? The speedo is of course as inaccurate as in any other car (for no valid reason), but the trip computer on an already 10 year old Merc does not read the speedo but the sensor readings on CAN-bus that are much more accurate. So the 115 km/h average probably means cruise control setting 120 on the speedometer?

    Hi. I can't see the formula for the degradation/cycles on the Tests File, but i think the logic behind it is flawed. For that result to have meaning, degradation would have to be linear and we know it is not, most of the degradation happens in the first cycles and after those it drops in a more linear matter if nothing abnormal happens. So a car with 200 cycles and 4% degradation is not worse than a car with 600 cycles and 7% degradation, that is because both could have had those 4% drop in 200 cycles and the other 400 cycles just add 3% of degradation. And by you calculation it looks like the those two cars would have different results but you can't be sure the first car is worse because the car still didn't do those other additional 400 cycles. Hope you understand what I'm trying to say.

    Think about this nugget: with an EV, the moment you disconnect your car that is 100%, the efficiency of your vehicle drops as you drive.
    If your battery 🔋 weighs 800kg, at 50% you're hauling 400kg of dead weight. Imagine your battery reaches 50% charge it is like you gradually picked up 5 grownups for the drive.

    Accuracy of degradation test in cold weather?
    I did a similar degradationtest with my Ioniq, 28 kW, from 2019, with 32000km. The car was changed to 100% in my cold garage ( ca 1° C). The charing stoped three ours before the test started. The I drove i on highway in constant speed at 90 km/h down to 2%. Outside temperature was -3°. The consumption was 13,3 kWh/100 km and the range was 175 km. That makes a total energy consumption of 23,275 kWh (=98%). 100 % = 23,75 kWh. If I assume that the battery hold 28 kWh at the start ( when the car was new) that makes a degradation of 15%. Is the assumption correct or does the battery hold less in cold weather?

      No. The first cycles will cause more degradation and after those it starts to slow down to a more steady rate of degradation. That happens because the chemicals inside the battery are still "green" at those first cycles and as they "mature" they become more stable and settled in, that makes the rate of degradation to slow down after those initial cycles.

    Degradation is a bad thing. And it is bad because you start with so little, that any amount is drastic. First you get like around 20% less then what is stated on the label. And to be fare this is exactly the amount (20%) with all the ICE engines and their consumption. But their fuel capacity is big and filling speed combined with filling stations availability makes those 20% more fuel consumptions just irrelevant. Also I just looked at the speed tests. The difference between 90 and 120 km/h is like mind blowing. Between 20% and 30% less efficient with 120km/h. With ICE cars most of the time this difference is between 0% - 10%. 20% is max for passenger cars, but there are some cases when cars are more fuel efficient around 120 then 90. May be pickups or Vans will reach 30%, may be. Unfortunately those 30km/h are more than 30% increase in speed and depending on how far is your destination it might mean a lot of time spend on the road. Lets say 200km, with 90km/h this will take ~135minutes. With 120km/h it will take ~ 100minutes. 35 minute difference for 200km is a lot. Here where max speed is 140km/h on the highway you can get 400km with only 3hour drive without stopping for a brake. And this is the main route for summer weekend vacations. I do not see that happening with any EV on your table. You either slow down and stop for a brake or you keep up with 140km/h and stop for a charge. Both will take the same time, one of them will be more expensive and if you find a spare or a working fast charger.
    And this is why I do not think that Pure EV's are the answer. An enormous vehicle with so much resources in, big battery, big everything and it gets just around 300km of range with 120km/h speed. And even that is not enough, anything less is just waste of time. I do not see the point of that. What are you saving. Make a plug-in with 1/3 of that battery, with around 80-100 city driving real world range around 120-150hp electric motor suitable for everyday driving. Then leave the rest to a small ICE engine with the same power and 35l fuel tank.
