Condolences to all in the rest of the country with this brutal weather. About all we had here was a 4.4 shaker overnight.
BDG777 a few observations and suggestions.
1. Mitsubishi EVSE: going from 8A to 12A is a 50% increase in power supplied to the car. You will have absolutely no problem fully charging overnight. What you do is plug in the EVSE, push the button on the EVSE to change it to 12A, then plug the car in (you can't change from 8A to 12A after you've plugged the car in).
2. Typical charge rate at 120vac 8A is four bars for five hours of charging. Typical charge rate at 120vac 12A is six bars for five hours of charging. Depending on the weather and how you drive, in warm weather and no HVAC, one bar normally equates to between four to five miles of driving. Figure half that for your present serious winter conditions.
3. REMOTE at home: I would not hesitate to use it in the morning before leaving for work. Even if you lose a bar or two, why not start off being comfortable? Simply leave the seat heat switch ON for the entire winter.
4. REMOTE at work: you have an L2 Blink in your parking lot. After work, why not simply pull up to it, plug the car in, and using the REMOTE heat or defrost your car for 5-10 minutes before taking off for home? You will lose negligible charge, if any.
5. Heater/defrost settings - there's a good writeup somewhere on this forum for optimizing these settings. Note your RR display: it not only drops when you turn on the heater, but it also drops in response to the fan speed setting. To maximize range I would turn on the heater sparingly, otherwise leaving it off completely.
