finish charging as close to your departure time as you can and don't charge to 100% if your one way destination does not drop you to 80% SOC or lower.
Don't charge at work on L2 AT ALL if you do not absolutely need it to make it home and even then, I would still recommend you stopping on the way home for a 15 min QC instead. Reasons are L2 is too slow and its simply a few hours at high SOC during the hottest part of the day.
This I have come to believe is THE NUMBER ONE SOURCE OF DEGRADATION for many of the people here.
How significant do you think this is at battery temps <70° F? I charged my 2013 to 93% this morning and had a post-charge temp of 60°. We are on a fairly early schedule some days, which happen to be the days we have the most after-work driving (roughly 11 kWh between leaving work and parking for the night, when lights and climate control are on for most of the trips). In summer, an 80% charge should finish the day above 30%, but maybe not in winter.
It's VERY convenient to jump on the L2 at work when we come in. All three were empty when I parked today. Utilization is pretty high later in the day. When I went back at 9:30 to unplug (two hour limit on use of those spaces), all were occupied, and I'll bet someone will be in the one I vacated pretty quickly. So, if I don't charge when I arrive, it's likely I would have to run down the stairs to the garage more than once in the early afternoon to find an opening. (Which, admittedly, would be less of an impact on my job than sneaking looks at the forum!)
The "cost" for me of charging at home is not so much the ten bucks or so per week, but the inconvenience. Our garage is too full of recreational equipment to put the car in, so the L1 has to be run out the cat door in the garage door to the car, deployed and put away every time it's used. Add the fun of doing this in the rain, and the few seconds needed to pull up to the L2 at work first thing in the morning looks really good. OTOH, that will seem less "worth it" if the car has 1 kWh more degradation in a few years. I am hoping to eke out driving this car well over five more years.
