2500 amps? I don't think liquid cooling is enough to allow for that.
You are probably thinking of the megawatt charger for the semi, which is different.
A regular V3 supercharger caps out at 250kW. There are rumors that the V4 might get closer to 400kW, but as far as I know those remain rumors. There's also a rumor of an upgrade of V3 superchargers to about 325kW, which would at least be getting close to CCS1.
Only going on what the article says "the Tesla charging connector is the most proven in North America, offering AC charging and up to 1 MW DC charging in one slim package".
