Bjørn Nyland has been driving the new Leaf in Ladetour recently, which has a nominal 100kW charging rate. So we were looking forward to seeing how that works out in the real world.
The max speed he got was.... under 50kW, just like previous Leafs (but no #Rapidgate). Why? Nothing to do with the car - it's that almost no CHAdeMO stations actually support more than 50kW, even if they support significantly more for CCS. Bjørn couldn't find one, despite being in the EV paradise of Norway. And since CHAdeMO is seen as "on its way out", it's questionable how many, if any, will bother to upgrade their chargers in the future.
In short... who knows if you actually could get the theoretical 100kW charge rate. Even if you could in theory, good luck at getting more than 50kW in practice, at least outside of CHAdeMO strongholds like Japan. Possibly ever, if the trends don't reverse for CHAdeMO.
