That'd be an interesting idea, although there's some unique challenges from the US perspective.I wonder if they are going to harmonise the charge ports between US/EU to simplify production. Older stations would need to be retrofitted, however that didn't seem like much of an issue in the EU when the European standard was mandated.
The EU move from Type 2 DC-Mid to Type 2 CCS only affected Superchargers - for AC charging, European Teslas used the same Type 2 standard as everyone else.
Moving from the proprietary Tesla connector to either Type 1 CCS or Type 2 CCS for cars would cause major problems with the fleet of installed AC chargers, including at destination charging. You'd need to provide an adapter from the proprietary connector to either J1772 or Type 2 for those cars. Additionally, if you used Type 2 CCS, you'd still need to provide a J1772 adapter (just J1772 to Type 2, instead of J1772 to proprietary connector) for charging at unbranded public charging. (And, if you shipped Type 2 native Wall Connectors, you'd need to offer Type 2 to proprietary connector adapters for the existing fleet, or offer retrofits to Type 2 CCS (which isn't even practical on current Model S/X, unless you convert them to Type 2 DC-Mid, at which point you need three cables for a while on Superchargers).)
(I agree that the world standardizing on Type 2 CCS would be helpful, but I see the costs to Tesla being rather high to do it.)
Would there also be a need for a new charge port if plaid pack chemistry allowed higher charging speeds than currently available? not sure what the limiting factor is for the current charge port design?
There is, AFAIK, some headroom to go higher voltage in the existing connector. Going for something like 118 cells in series would get you a maximum voltage of 495.6 (within the 500 V limits), and would increase charge power by ~23% over today with no increase in current...
