It's -20C today in Canada where I live, and this is when ICE people plug in their block heaters. So I didn't feel too self conscious about using my charge port at work for the first time. All they currently have is 120V outlets... for block heaters. I'm working on getting charger stations put in... next year. Anyway, at the app-reported charge rate of 6 km/h, the math says it will take my full 8 hour work day to get back to the same state of charge as when I left home this a.m. So that's fair. Of course, my main reason for plugging in was to have stress free use of interior climate warming feature before heading out... not feeling bad about subtracting useful range in doing so. Or will the mobile charger at 120V12A have enough jam to do both? Maybe not enough to maintain at least some charging rate AND do climate control warming when it's -20C outside. I'm about to find out later in the day... Also, I imagine keeping a "trickle charge" on all day is a means of keeping the battery pack warmed, hopefully avoiding the dreaded "regen has been disabled" warning I get when having parked outside in the negative temperatures for hours. We'll see. Report to follow.
