It's not a real scenario to fully deplete your battery when you get home and where you HAVE to have a fully charged pack inside 2 or 3 hours.

You only need to charge to get to a fast charger

edit: yes, Hummer is 200kWh

There's more than one Tesla onboard charger...literally. You could get master/slave OBC's in a Tesla to double up the 45A (to the battery) "19kW" charger to 38kW...

You can do a lot more than 48A from the wall...

You are correct. The 38kW was a Brain fart where I used the pack voltage.

My Model X Signature would, however, pull 72A from the EVSE, a lot more than 48A, and a Master/Slave OBC will pull 48A each (23kW wall power), again a lot more than 48A.
