    Any chance the car will allow car to carcharging? You know, when you've blown your KWh and a good Tesla buddy can spare you a few electrons? Answers, thoughts?

    Cheers.

    It seems like it should be feasible, especially if both have supercharger capability. Probably need a special adapter, though.

    Jomo - Good one!

    TXjak - YEs, just in an emergency situation. DC current transfer.

    How about going double Galaga style? You know connecting up side by side and blasting away.

    For the record, I don't think this is a good idea and do not try that at home or anywhere else for that matter.

    I don't think it's a good idea either, sort of like siphoning gas from one tank to put in another - option of last resort. But it will be essentially what a AAA type charge will be (battery to battery, unless they install an onboard generator on their trucks.).

    Actually, from my recall of the photo and caption I saw of one of their trucks, they did go the generator route. Don't remember the output they claimed, though.

    I think that picking up a charge from anywhere is a good idea if feasible.
    DC charging would have to be the way to do it. All they can do is split up the total charge between them [(CarA_Charge+CarB_charge)/2]. In other words, if car A was at 100%, and Car B was at 80%, they will both get to 90% and then stop. If A was at 100 and B was at 50, they will both go to 75% and stop.

    Seams like a good idea, but will require a DC to DC cable and "charger curcurit" to regulate/negotigate the charge speed.

    DC to DC makes it posible to charge as "supercharger" - e.g. charge 50 miles in aprox 10 minutte
