We did a charging station for a Chevy       Volt earlier this year.  We actually ran the charger for about a       week to come up with the design, based on their mileage ,etc.        This also accounted for battery and inverter losses.  We added       about a 3400 w array (off grid) and they drove about 40 miles       round trip/ day.  We went with the 120 vac slower charger to keep       a slower and more efficient discharge rate of the main system       battery.  I believe that charging at slower rates is almost always       going to be more efficient due to Puekert's exponent.

Friends:
 
Have             any of you researched the energy usage for an electric car?              The car in question is a Tesla Sedan.
 
Thanks             in advance.
