That is a lot of hype and short on accurate facts IMO. While the battery in a models will certainly take a 175kw charge I am not at all sure the cables can handle it. I watched Jack charge a single cell out of a model 3 at 10 Amps to 4.2 V. There are 46 cells in parallel in a Model 3 so that is equivalent to 460 Amps. 460 x 96 modules is 182Kw. The battery wasn’t even warm. However, even if the rest of the system can take 175Kw you still won’t charge the car in minutes. A Tesla Supercharger is limited to 250 Amps. The Hypercharger likely has a current limit as well. In addition, power is Amps times Volts so you don’t get max power till the voltage rises. At empty a Model 3 is around 270 volts. 270 x 460 A is 123KW. You can’t cheat physics.
