There
are times when I wished our Ioniq 5 charged more slowly, like when I want to grab a bite. On a good day, back to 80% in 15 minutes, with a 10 minute grace period before the per-minute charges kick in, and there's barely time to sit and eat the meal.
But one thing 5 minute charging would improve is throughput. We're in the middle of a house remodel, and no room in the garage at the moment for the car to get near the charger. So we've been charging at public chargers a lot, and in the three or four times I've hit a public charger recently, I've had to wait on another car to unplug about half the time. Granted, this is the Seattle area where you can't swing a golf club without hitting an EV, but I've had the same problem on road trips, too.
