I think fast charging negatively impact battery life because of the heat it produces. It would be nice to be able to choose the amperage we want for a specific charge, when we're not in a hurry.
Which is why i still think that the best solution at the moment is still battery swapping stations. That way you get the best of both worlds. Your vehicle is back at full charge within a couple of minutes (the only limitation is how fast the mechanical operations can be performed), and the batteries themselves can be charged as slowly as needed to preserve long term battery life.
i mean the engineers developing this must be taking that into account, we don't have to be worrying about this.
I would imagine they've considered batter degradation here. It could be that the approach they use doesn't cause significant damage to the battery.
They actually tell you it’s better to charge it with the slow charger most of the time. The fast charger does have a negative effect on battery life. I don’t know how significant it is though.
It'd be interesting to see what the difference is there. The ideal would be if you have a charger capable of rapid charging, and you can dial it down if you want to assuming there is a negative effect on the battery.
