V2 vs V3 charging speed on legacy S/X

[brico84]

I have a 2017 S75. It tops out supercharging around 110 - 120. So my question is.... now that I am seeing all these new chargers at 150KW, 250KW, etc, will I see a speed increase at the higher KW superchargers?

For example, right now I can stay at 110KW+ supercharging for a few minutes before it starts to decline down the curve. I know the higher level superchargers won't make it go higher than 110KW, but I am wondering if maybe it will maintain the higher level KW transfer rates for a longer period of time, or will it be exactly the same no matter what?

Thanks, sorry if this a stupid question.

No. The tapering effect is due to the car switching from constant current (CC) to constant voltage (CV) phase, and the BMS will make this switch at the same point in the charging session regardless of what it is plugged into. And once it's in CV phase, the battery itself is only going to take whatever power it can accept at the given constant voltage.
