What if Tesla made semi truck PowerPack based super-chargers

    There're posts around that during the unusual rush to see the solar eclipse
    there was long wait times at SuperChargers..
    and with the TM3 coming this may happen more often.
    So I wonder if this might be a partial solution?

    What if Tesla made semi-truck based Super-Chargers?...
    • each completely filled with PowerPacks,
    • (maybe have natural gas generators too, or a 2nd generator truck, that are only used if pre-charged packs are depleted),
    • that could simultaneously feed 10+++ EV cars,
    • and send them (someday anonymously) to park in lots along routes that are expected to get congested
    (or are used until a more permanent solution is built).

    Hmmm, does anyone know how many cars 1 PowerPack could possibly charge simultaneously or in total?
    Would this be competitive to the price of building a permanent Super-Charger site?

    Thought a little about this previously, works even better with self driving semis... Would have been handy during eclipse..

    Please move this from the Model 3 forums to charging forum.

    Consider this:
    A supercharger site on average costs $300,000

    a 53 ft truck can hold 24 powerpacks if you didn't need the inverters, 12 if you do. Even at a price of $200 / kWh @ 210 kWh a piece with the powerpacks alone it's cheaper to build an entire supercharger site complete with stalls and everything. Semi trucks typically cost over $100k so consider that cost as well.

    A Powerpack would only charge 2 or 3 cars as they hold 210 kWh. It would be very expensive for them to do this and not help out that much.

    According to the Tesla website 1 powerpack is 50kW (AC) and 210 kWh (AC).

    So, modified to do DC charging, it could charge 1 or 2 cars at a time, and charge up to 3 full charges (4, SR Model 3) before being depleted. You might get at most 20 on a semi.

    Thank you kindly.

    Sorry, I knew this wasn't the ideal spot but didn't see a charging forum.. and don't know how to move it.

    It's interesting for an emergency vehicle/tow service on a small scale, but doing this instead of building additional supercharging stations is not a good financial move and likely not sustainable.

    How about Powerpack based battery swapping for semi's? ;)
