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.
