I have Gen 1 mobile connector that came with my 2015 P85D dual onboard 40 amp charge circuits ( 80 amp or 16 kw capable)
On new 2020 mobile connector is 48 amp max at 220v. A) will car charge at 16kw ( with a HPWC? B) will it charge faster with 2015 gen 1 mobile unit than with new 48 amp capped unit?

It's always the lower number of the two. Your gen 1 mobile connector will only charge at a maximum of 40 amps. If you have a wall connector capable of 48 amps or more then that's what that car will charge at since it has the dual onboard chargers and is capable of 80 amps.

Your 80A capable car can be charged at 80A if you hook to the correct source.

You can hook to HPWC that's properly configured with a 240V 100A breaker and your car can charge with 80A 240V fine.

(EDIT: HPWC Gen 1 and Gen 2 could provide the above spec but current HPWC Gen 3 with WiFi are capped to the maximum of 48A.)

If it is hooked a Mobile Unit that's hooked to a properly configured circuit or better such as 240V 100 A breaker, the maximum that your car can get is limited by the Mobile Unit.

Gen 1 can supply a higher Amperes at 40A (and kW) than Gen 2 can.

Gen 2 Amperes and kW are capped at a lower limit (32A).

Gen 1 mobile maxes out at 40 Amps in the US, but numerous people have had the plugs get hot and melt down. It’s best to manually adjust the amps to 32 to guard against this. The Gen 2 mobile connectors max out at 32 Amps, I believe.

A 14-50 outlet is limited to 40a continuous (car charging). Done. The Gen1 UMC would support this amount. Gen2 supports 32a on a 14-50.

a 14-50 is the highest power adaptor available for the UMC.

If you want 48a, you need a WC (Gen1, 2, or 3) hardwired.

If you want more than that, you will need a Gen1 or Gen2 WC, also hardwired.

Yes, your Model S will charge faster with the wall connector than with the Gen 1 mobile connector.

You are wrongly calculating 16kw.

220*48=11,520 or 11.5 kw.

I have gen 2 model s and charge with 50a and get 35mph
