alt Hacker NewsI have as far as I'm aware the cheapest 800v car on sale in the US (Hyundai Ioniq 5) and in the right weather conditions a 20-80% charge is legitimately 10 minutes.
The weather conditions do unfortunately matter. Travelling during the post-Christmas blizzard last year was very much less than ideal. The battery heaters in my car could not keep up with how bitterly cold and windy it was and I had multiple 30-45 minute charging sessions because it wasn't ever warm enough to accept more than ~120kW.
I'm looking forward to traveling with it in the warm season and seeing how things compare.

Same with the EV6. Charged at a Rivian station from 20-80% in 15 minutes.
Now (in China) there are also cars with sodium-ion batteries, instead of lithium-ion batteries.
Sodium-ion batteries have the disadvantage of a worse energy per weight ratio, but they also have an advantage (besides the fact that they will become cheaper when their production will be more mature): they work much better at low temperatures, not losing capacity or charging speed until minus 40 Celsius degrees.
Therefore, they may become preferable in colder climates, where they will not have the problems described by you.
