No free charging here! From what I could tell it's 0.45 a kwh. That's about the same as gas prices for my PHEV. I of course fill up almost exclusively at home where it costs me under 1.25 for 54 to 57 km of driving. My battery is a 13.5 kwh PHEV battery that keeps about 17% in reserve for hybrid driving. So really 1.06 to fill it up with electricity for 83@% charge of a 13.5 kwh battery. Our electricity is about 0.095/kwh where we live. Gas is $1.67/liter today, )was much higher a few weeks ago at $1.85/ liter)
So gas to drive 55km is $6.06 at today's price as my Tucson gets 6.6L/100 in hybrid mode. Doesn't really pay to publicly charge a PHEV unless the charger is free. Lately the free ones seem to be not working some of the places I frequent, and who really wants to wait 2 or more hours to do so anyhow.
