The battery has to be warmed during charging, when the air temperature is cooler. This uses more energy, the cooler it is outside.

OP might be unfamiliar with CARE (which apparently stands for California Alternate Rates for Energy). It's CA specific and for low income households/people only:

CARE rates apply to households with either low income or a member who is disabled. We qualify because my son is permanently disabled. In addition we qualify for Medical rates (larger baseline allowance and capped tier 2 rate). Even with those discounts, my rate is $.15/KWH. I have 16 KW of PV that produces 26,000 KWH annually. That gets me to essentially 0 consumption from SDG&E. I use a lot of power because I live on a 5 acre ranch where there aren't any sewers or city water. The house is all electric at this point except for the propane stove. I've reduced my propane and electric bills by $5000-$6000 annually. And yes, going solar was cheaper than paying SDG&E and Amerigas. Adding the Leaf to replace my Maxima saved me $3000-$4000 in gas annually depending on the price of gas. $8k-$10k/yr in savings pays for a lot of PV.

I am in CT, and have noticed SIGNIFICANTLY longer charging times during the recent cold snap where daytime highs have been in the teens and twenties and overnight lows around zero. Haven't measured them yet. This is with Level 1 charging.

I tried to opportunity charge at an L-2 station at a Chili's last night. Slow as molasses! It's frigid here too, but even with temps up in the teens it was only about 1/2 as fast as usual. I think I gained 5% charge in 20 minutes, when normally it would be 10%.
