    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.
