Congrats on your car! I've loving mine so far.

there is no real efficiency gain with 220v over 110. the formula is always the same:
Wattage / Voltage = Amperage
you are billed in kilowatt hours, the 220 will pull ~the same kilowatts as 110 but in less time because they are both charging the same wattage motor. so wattage in the above equation is constant. so you will be billed on the watts used to charge to 100%
there's a voltage drop in the cable, the bigger the cable the bigger the drop, the formula for this is slightly more complicated but if the cable is only 3-5 feet it doesn't really matter.
