I keep the house at 60 sometimes lower so I don't mind cool. as long as the chill is gone I am totally ok.
its 54 miles. 19057 intersection of rt13 and edgely road to 08215 egg harbor city (right on rt30 just before rt50)
over the burlington bristol bridge down jacksonville road to rt206 to rt30
max speed 50mph the entire way. (posted limit) average speed 35mph IIRC) stop and go in the beginning rt13 to the BBB to rt130 once on jackson ville typically 4 or 5 lights the rest of the entire trip to destination so a pretty constant 50mph non stop once on jacksonville...
With these additional details, I think that there is a pretty good chance that you can make it for several years to come except when it is actively snowing. You will need to get comfortable with using the lower part of the battery pack; there is still plenty of useful charge below "Low Battery Warning". I get similar distances quite easily in winter at those temperatures since I don't need to use the cabin heat (dressing warmly, the norm in winter anyway, and the steering wheel heater are plenty for me most of the time). But some people are adamant that not using the cabin heater during the trip is not an option.
In my view, the things you have going for you are:
• The relatively slow speeds of your commute; there is a huge difference in range at your reported speeds versus blasting along at 65 mph, as so many people do.
• Your comfort at cooler temperatures (I keep my house thermostat at 62º mornings and evenings and 52º at night). If you can do this commute with preheating and skip the cabin heat, it will help the range. Be aware, however, that the 2012 has no heater-off switch. If you need to use the defroster the heater will come on and suck down power. [I don't think they still have it, but EVSEupgrade.com used to have a climate control mod that will allow you to turn the heater off and still be able to blow air on the windshield. It is a big help on my 2012. Another option is a DIY approach: Easy Climate Control Fan-Only Solution - 5 cents, 5 mins
A possible problem would be if you park outside at home. If you have an enclosed, attached garage, it should help keep the car and battery warmer (a cold battery has reduced capacity/range). Charging the battery will help warm it up some. At work, the combination of driving to get there and charging while there will also help keep the battery warmed up some. If you park outside or your garage gets below freezing at night, that will reduce your range.
I expect that as the temperature declines you will get a feel for how your range also declines and can decide if you are pressing your luck. Be aware that wind, rain, and snow (of course), can reduce range significantly. If that happens, the way to make the trip is to slow down, since you don't have any enroute charging options.
Some things to consider: what if the workplace charging isn't working or is blocked? What if it starts snowing hard during the day? You aren't getting home in the LEAF!
