Oh wow you’re right. Those supercharger stations must be pushing a lot of amperage. I had no idea it only took 15 minutes for 200 miles range. I assume there would be battery degradation over time but still impressive.
So batteries are happiest to charge with high power between like… let’s call it 25-60%. Most of the time the cars will have you pull over to charge at 10-20% and you’ll only charge up to 70-75% tops.
Charging in that band would take like 15-20 mins. If you charge to 100%, it could easily take 30 mins just for the final 30% because the batteries can’t fast charge as they top off.
It really depends on the vehicle. The fastest ones (Kia/Hyundai) will charge 10-80% in ~18 minutes (350kW max). Something like a Nissan Leaf can take an hour or more.

There is degradation over time. Long term results are showing 10% capacity loss over a 10 year period. So if you start with a 300 mile range, after 10 years of use charging and discharging, you have 270 miles of range.
You’re only charging for 15ish minutes.

Anywhere from 150 to 350 kilowatts! Usually 400-800 volts. It’s pretty serious.
