    I left for a long trip to Europe and wanted to share this information with you.
    When I left my battery was at 237miles on June 1st 2016 end of the day.
    on July 26th end of day I had left 126 Miles.

    This give an average consumption of 2 miles per day when car is left unplugged.
    So I could live the car unplugged for about 4 months.

    Ciao!

    12 V is entirely backed by the DC DC converter so as long as the main pack has enough juice, so will the 12 V. Charging does nothing for the 12 V.

    Just because you "could" doesn't mean you should. Tesla says plug it in to best preserve the battery life. But hey, it's your battery so you can abuse it if you want to.

    Doesn't anyone RTFM anymore?

    Interesting information, thanks for posting. Note that in very cold climates the loss could be greater. You didn't say whether you car was indoors in a climate controlled environment, outdoors in the shade, or outdoors in the sun.

    Was there a reason you decided not to plug your car in while you were away? Was it parked in an airport parking lot with no plug availability?

    Did you have the Energy Saving switched On and the Always Connected OFF?

    Good to know that situation works for you. What kind of charging do you have at your office location? 240V? Amps?

    Which is unlike the Kia Soul EV that I had plugged in and accidentally left in ACC mode (as opposed to ON) overnight to install the recent CarPlay/Android Auto update. Ended up with a dead 12V batter and a day of trickle charge to get it back on the road...

    Yeah, it's got this weird "not quite on" accessory mode and Kia's solution is to show a brief warning on the display. Otherwise it's been a great EV compared to the other limited, non-Tesla crop with a decent range that are available at the moment.

    Yeah, I do kind of like the Soul EV, and might be considering that to replace our Civic Hybrid eventually. I saw an article that was "What is the best EV?", and they split it out into: if money is no object (Tesla) or if money is an object (Soul EV).

    Isn't there a proper protocol to follow when not using your car for weeks/months at a time to prevent battery damage? I thought it was like leaving your car at half charge, and keeping it plugged in.
