I'm seriously considering attaching a trailer with a generator to my Model S to make it possible to drive from Seattle to Alaska. There are several generators available out there that can fit the purpose. For example: Generac 5735 GP17500E - 17,500 Watt Electric Start Portable Generator It's lightweight enough to put on a trailer that can be towed by a Model S with an Ecohitch. I have even tested this generator at a local dealership, it works perfectly at 40 amps with a NEMA 14-50 plug.r Of course, the next question is: "Can I charge while driving?" So I'm wondering how exactly the "charge cable connected" interlock works. Is it possible to work around it by connecting to one of my installed dual chargers? It's also quite likely that this insane mode will cause all kinds of calibration issues for the BMS sensors, but I can live with that.
