The Audi e-tron GT charges at 270KW. Pretty close already. A standard petrol/gas pump pushes 22MW, or ~7MW equivalent when taking into account ICE efficiency.

- gambiting 5y agoRight, but I think aiming for petrol pump equivalency isn't very helpful when planning a charging standard right now - this theoretical 7MW charging station would be absolutely insane in order to provide that much power through a single cable(I would love to see a calculation for how thick it would need to be to make that happen), second of all how do you cool down a battery charging at 7MW, and third of all how do you get that kind of power to the charging site(especially if we're talking about multiple charging points running at once). Even right now the new FastNED or Ionity charging stations that have the latest 300kW chargers are very difficult to install due to the huge power requirements, especially with several of them running in parallel. Tesla Superchargers do actually slow down when multiple cars are charging at once. So going back to the charging standard - the "default" CCS plug supporting "only" 350kW is going to be sufficient for a long time I think. And if it's not it can be made to support more with very minor changes to the design - after all it's literally just two prongs thar carry the power.
- Symbiote 5y ago7MW is about half a high speed train at maximum power, but that's using a 25kV supply. But running the cables is presumably easier when the railway has that convenient strip of land all across the country.
