...and lived to tell the tale.
After some unplanned trips and bad math gymnastics, a missed CCS charging opportunity, and the extra current draw of toting the whole family in the car, I arrived at home Wednesday night with a 2 or 3% SOC on the display.
"Home" in this case is the duplex we're renting while I remodel the house. Home = no charge, house (& work) is where I charge during the day.
So I figured I'd get the kids up early and we would charge downtown on a Level 2 station while getting breakfast, putting enough juice in the box to get the i3 to the house and get the kids to school.
Wouldn't you know that the bank of Blink chargers downtown had some sort of communication breakdown with Blink HQ and were therefore "on the blink" (¯\_(ツ)_/¯) -- they couldn't authorize my charging session.
There are other chargers nearby but none I've been to, and the clock was running. So I trudged back up the hill the "home" and crept the final few blocks effectively on E -- I think it was 0% and 1 mile remaining when I parked.
Thankfully I have a backup vehicle, so I wasn't really sweating it (though untested until now, this post gave me reassurance: viewtopic.php?t=1918
Thursday night I brought home a 100' extension cord and nourished my depleted battery. Friday morning's drive was no drama, and I visited a CCS charger after starting the day.
I'll say this: I appreciate that the i3's state of charge is stable. If this were my phone, I would have been stranded at 5 to 7%!
