  1. The BMW i3 94Ah has 94Ah NMC111 (Also known as NMC333) battery modules rated for 4600 charge/discharge cycles to 80% capacity made by Samsung SDI.

    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.

  2. 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.

  3. 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.

  4. 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
