I purchased the 2012 Volt 11-30-11 and since then my average kw's per day went from 54kw daily to 162 kw daily. This is a 108kw increase per day..I am using the 110v charger. is the problem my charger or is it constantly pulling electricity ..the cars storage temp. is about 40 Deg F. average..I would appreciate any knowlage on this..P.S. there has been some talk on electric rates..Last month I used 4689 Kw's and my tatal bill = 400.42 do the math and this months cost is $0.0854 per Kw. for Winter. Summer rates go up about $0.025 more. In Nebraska. More math is telling me thay its costing me about $ 9.22 a day to drive 15 miles. something is wrong..
