I would imagine it gives out DC, otherwise you'd need an enormous rectifier/regulator in the car to be able to handle that kind of power. It would make more sense to rectify and regulate the voltage at the charging station rather than burden each vehicle with the bulk and weight of the extra circuitry.

Then someone will look at that and say, hey we know how to build small efficient diesel engines cheaply so why not cut out the heavy expensive batteries and just put diesel in every vehicle.....

It depends by vehicle - the Zoe I had was AC charging. It's an AC motor anyway, so all they are doing is reversing the direction through the conversion system

Even if the vehicle receives an AC charging feed, there will have to be rectification and voltage regulation for charging. For slow-charging vehicles it's practical to have that circuitry on-board. But, if you're fast-charging at hundreds of amps, you're gonna need some pretty big rectifier diodes!

Yeah exactly ^ The articles I've seen say that slow chargers tend to feed AC in to the vehicle's on-board charger up to about 20KW, but those 100+KW fast chargers feed DC direct in to the battery and have the power electronics in the charging station.
800V @ 500A DC |

That is a staggering amount of power! In fact I'm amazed they can fit the circuitry that can handle that into the charging station.
To put it into perspective, the closest PSU I can find is 800V @ 400A, available courtesy of the Suzhou Lingfran Electric Co., Ltd: https://www.alibaba.com/product-deta...445757754.html Should just about fit in a Tesla boot I reckon!

I'm amazed they can fit a consumer-safe connector of that scale in to a car.
Apparently the connector and the cable are liquid cooled, and the proof of concept 400KW charger's cooling system could heard over the neighbouring truckstop! |

Yeah, that's certainly some achievement to produce a connector capable of handling that amount of power safely!
Especially when you consider the average domestic mains plug/socket tends to char and burn if you run it at the full rated power for more than about 10 minutes .... And that's just 240v @ 13 Amps!

Like everything else in the pipedream realm
Nobody understands the power/weight ratio. DC at that power needs a rather fat cable. Car starter is 12 volts @ 100Amps and look at the size of the battery to starter cable. Think of the heat that would be generated if a connection became slightly loose. Then the connectors being used by Joe Public. Hopefully not in my time.
