...There is something wrong with that car, charging station or the driver if it takes an hour to charge from 10% to 80%.
Here is a youtube Tesla Model 3 report charging at -7C from 10% to 80% in 37 minutes...
Nothing wrong with either the driver or the car. Really nothing "wrong" with the charging station except that it wasn't designed to be very fast. The comment in the video was with regard to the
50 kW fast-charge stations from Circuit électrique as
shown in the video, not the faster charge stations to be found elsewhere or that will become more common over time.
"Most of the chargers that were on convenient routes to my destinations
were only 50 kW fast-chargers. If the IONIQ 5 was at 10%, it would take over an hour to charge back up to 80
on one of those."
The difference in your video is the higher wattage charging station. As your video also shows, the charge rate will decrease as the battery charge level increases due to internal resistance building up in the battery. This is normal with current EV battery and charging technology.
As a side note: Neither a Tesla nor Hyundai will force you to stand in the cold Canadian air while charging. That's just a case of exaggerating and embellishing a story for a reaction and attention.
You can sit inside the comfort of your car, go have a cup of coffee, or grab lunch at McDonald's as shown in one of the other videos. Actually, dining in comfort while charging the car was a pretty common theme in the IONIQ 5 road trip videos, which makes more sense than standing outside for no reason and freezing.
