The modern charge standard is not 480v it’s 800 volts BMW, Porsche, KIA, and VW already have vehicles that can use the 800v standard. To fully charge 82kWh in 5 mins would take 1200 amps DC which sounds like a lot but your avg diesel starting motor draws well over a 1,000 amps at 24v and those cables are air cooled not much thicker than your thumb. The 800v standard uses liquid cooled cables and would be of similar thicknesses. The next standard after 800v will be 1200v DC polycarbonate and silica insulation at those voltages is a few tens of MM thick the plugs are black when plugged in they are fully two-way digital communication for the charger negotiation protocols only when the plug is fully seated and liquids flowing and ground safety verified would current be allowed to flow. The process is an order of magnitude safer than a user manually pouring flammable liquids into an open container hole with vapors leaking out of said opening. It is impossible to be shocked by a DC fast charger the whole cord is off line until a complex handshake happens and if you were dumb enough to pull the plug which is locked in my a magnetic lock I might add in a millisecond the charger senses the break in continuance and cuts off the DC current simply put you cannot be shocked even with willful user error or malfeasance.
The question was for a Tesla. Those vehicles you listed have 800V battery packs, which is perfectly suited for 800V charging without lossy and expensive DC-DC converters. Teslas cannot charge at 800VDC.
Teslas use 375V battery packs, and their Supercharger is 480VDC.
