Supercharging A Kia EV9 Shows That Tesla Isn't Ready For The 800V Revolution... Yet.

If you were hoping that Supercharger access would revolutionize EV charging, well... There are a few things you should know. If you have a "400V" EV then yep, Superchargers are the place to go for reliable charging with short cords and free adapters. If on the other hand you have an 800V EV like a Lucid, Porsche, or a Kia, Hyundai, or Genesis... Then things are a bit different. You see, V3 Superchargers don't natively put out the voltage required to charge your battery. Yep, even on 800V EVs that aren't actually 800V like this Kia EV9. In order to charge, these EVs have to boost the voltage using an onboard DC-DC conversion circuit that not only reduces charging efficiency, it reduced charging speeds dramatically. 10-80% in 20 minutes? Try an hour if you're low voltage charging....
