The only reason I said double was to discount winter explanations. He mentions what? 25 miles is longest trip he might take? He uses other options for anything greater. So sorry, no need to charge to full.
One reason to charge to full is to avoid discharge to near zero.
Like cash in the bank, having reserve range is always a good thing. If you plan on arriving home with 0% left, what if there is a detour? Or you have to go someplace right after getting home? Anything from a run to the grocery to an emergency.
Battery life will be better if discharges below 30% are avoided. On the flip side of this, leaving the battery fully charged especially when hot also decreases battery life. Staying in the center is best, and there is no ideal way to do this for everyone. So as a general plan with twice the range needed in summertime charge to perhaps 80%, and try to time charging to finish near departure time. In wintertime, charge to 100% if needed to avoid deep discharges. Worry a lot less about charging to 100% or leaving the car at 100%.
If winter is cold like the Yukon, you probably need a lot more than twice the summer range. For milder winters, twice summer range is probably OK.
