Sorry you don’t understand how preconditioning works in the cold.
Well, actually CHAdeMO is usually going to get you 33kw. Unless it's below zero, you'll be fine since the car will warm up enough while driving. I've never experienced any slowdown at CHAdeMO chargers in Oregon or Washington in the winter when my battery isn't warm.
Canada might be another story. Never taken my car anywhere below 0F.
But Bjorn has. And even with a cold battery in Norway, he still starts off at 37kw charging. Within 2.5 minutes the battery is heated enough that the battery heater turns off. And within 4 minutes he's getting full charge rate of 50.
So you have 4 minutes of slightly reduced charge speed. Lets see. 4 minutes at a 14kw charging rate difference. That's a missed charge of less than 1kw. But then the car is charging at 50kw. So not preconditioning will cost you like 61 seconds longer charge on CHAdeMO (125A).
And if you're using a CHAdeMO (100Amp) - there's no slowdown at all.
Still think preconditioning is necessary for CHAdeMO? It's nice, but I don't think it's necessary unless you live somewhere colder than Norway.
