Probably useful for trucks, marginal utility for your typical EV owner. Articles like this seem to be speaking to people who don't own an EV and are still focused on the ICE car model of "plugging in" your car periodically at a public location. That isn't how EVs work for the vast majority of people.
BYD has cars supporting this afaik. And working in the electrical charging point data sector at the moment, we see that fast charge is a breaking point to make people decide the switch is worth it.
Right now, EVs are only good for people who have houses with garages that let them charge. If you need to use street parking or something then EVs don't work. But maybe if such technology improves everyone can use EVs.
This is their first model that will be rolled out in the EU and the US so they might be more likely to see faster charging EVs including some that would peak at nearly twice that speed.
You're right, but many EVs today can't take full advantage of the faster chargers currently available. I have one of the faster charging vehicles available (EV6) and even at 350kW chargers, I've never seen faster than 200kW, and usually much lower than that.
