I want to know how they are getting that much energy safely delivered to the battery. That’s probably 200+ kWh of energy getting dumped into the battery in 10 min. That’s going to cause a lot of heat and require a massive delivery system. Maybe a local capacitor that slow charged and then dumps all at once, but I didn’t see any details on the article.
Possibly capacitors, but most likely there will be battery storage for charging systems. The Tesla V4 superchargers can deliver 1 MW of total power spread across 4 individual cars, but can only draw 350kW from the grid. To get the additional power, they have batteries connected to the system that charge up when the supercharger is delivering less than 350kW.
