...Then either I don't need the extra power that's in the truck battery, because I'm not there consuming it, and if it's that important, there's a smaller backup battery.What happens when you are at work or on a road trip...
Houses use the most power when you're at home, you know.
High amperage circuitry is super-expensive, which is why you wouldn't add any that you didn't need in the charging circuit. With DC charging, the car provides some information to the station, like voltage level and whether it's ready to charge or stop, but the station does all the work pushing the voltage. That's the point of a DC charging connection.I do not know, nor have I seen any circuit diagrams for the DC fast charging circuit on a Tesla or any other EV for that matter. It might be a direct connection to the battery, but I suspect there is some control circuitry in the DC fast charging circuit also.
Tesla does do some weird things by repurposing the conductors in the charging cable as need be, but aside from that, the connection to the battery is as direct as possible to reduce heat-loss.
