Rough calculations: 720 KM is 450 miles.My longest road trip is 720km which requires 2 x 40 min DC fast charging stops with Chevy Bolt in summer. The MME FE will need 1 DC fast charge for 30 min for this trip. Not a big deal. I need the break to have something to eat and use washroom.
Ontario and Quebec have a good network of DC fast charging stations on the major roads I travel.
As per my post #30, you have in the winter about 140 miles of range on a LR AWD then a 40 minute stop to get to 80% capacity. That will give you another 120 miles, then another 40 minute stop. You have now driven 260 miles with 190 miles to go. Another 40 minute stop to get another 120 miles.
I calculate three stops not one. This is an additional 2 hours of stopping time. Granted in an ICE, on a 450 mile trip I would stop once for gas, 10 minutes and two to minute "pit stops" total of 30 minutes.
In the summer two stops not one.
