Ah, that's a good commute for the LEAF. Yet I am usually skeptical.
11 bars is roughly 80% to 85% of the battery. Reserve the bottom 20% for sanity's sake, and you have about 60% of the original usable battery for the commute. That is about 12.6 kWh, assuming the car is about to drop a bar.
Assuming even in cold weather you can probably get over 3.5 mile per kWh, need about 9.7kWh at worst. So you are fine, this year.
Battery capacity has lost 3% to 4% per year. 5 year old car, down 15% to 20%. Assuming 4%, next year you might have 76%, year after 72%, year after 68%, and so on.
In year 3, reserving the bottom 20%, this leaves just 48%. This is about 10kWh. Still OK, and with a 20 percent safety margin.
DCQCs are only needed for longer trips. Unneeded for commute.
Things to watch.
Do find covered or shaded parking at work, if you can.
Check your garage temperatures. If much warmer than outside, add insulation and ventilation as needed to reduce temperatures.
