The big CATL cells can withstand 3C charge/discharge and can also withstand continuous charge/discharge of more than 1C. Take our 62kwh for example, fast charge power of Leaf is 47kw, at maximum current of 150A, we replace with180Ah big CATL cells, so the charging rate is even less than 1C.

    There are more than 75000 Nissan Leafs in Norway but no possibility to upgrade batterpacks. I have a 30 kwh 2016. Does a upgrade to a 62 kwh require any upgrade of brakes and suspensions? Does a switch to a bigger battery pack also require any upgrade of software and connectors?
    Maybe there is a need of a new certification from the authorities since the car probably gets heavier?

    • @CoraLiu-VIVNE
      @CoraLiu-VIVNE  9 днів тому +1

      Leaf is a very nice car, and it's a shame that it will become a disposable car if you can't replace the battery.
      No, you don't need to upgrade the brakes and suspensions for 50kWh or 62kWh. For the software, just reprogram the BMS and the car can will recognize the new battery.
      The 62kWh weighs 48kg more than the original 30kWh, but the 50kWh weighs almost the same as the original 30kWh, so maybe the 50kWh is a better choice for you people there.

    From 39% to 67% (28% of battery capacity) in 23 minutes with power 42kW gives total capacity around 58kWh, not 75kWh. Or I'm calculating wrong? Or charging curve (battery percents) is not lenear?

      @CoraLiu-VIVNE  Місяць тому +3

      Wow amazing! your calculation is correct. You are really careful and smart.👍
      Due to the mistake of the colleague who was responsible for installing the battery pack, the battery was installed with the wrong BMS at the beginning(installed as 62kWh). I found this problem when I was doing the fast charging test. However, it was too late to change the BMS and do the fast charging test again, so we continued to complete the test with the 62kWh BMS (the test results were the same). After the fast charging test was completed, we changed to the 75kWh BMS, and then did the high-power discharge test.

It looks like building new packs from CATL cells is pretty easy since they are large capacity cells compared to the original leaf cells. So, it only takes a few of them, compared to 96.
