Hi Mike - I also have an Escort EV, converted by US Solar/US Electricar back in 1992. It is powered by 18 US-125 lead acid batteries, and is quite heavy - 3,400 pounds as weighed on a certified scale (vehicle empty/ready to drive). http://www.evalbum.com/4331
I typically use about 450 Wh/mile for my normal 10 to 15 mile days, measured while charging. Longer runs (deeper pack discharge) tend to use the charger more efficiently since more of the charge time is in the Bulk phase as opposed to the Finishing phase of charging. I have seen as low as about 400 Wh/mile while charging after 30 to 40 mile runs. With my previous EV, I could measure energy used while driving, and the difference was about 200 Wh/mile reported while driving, and about 250 Wh/mile as measured at the plug after charging. Of course, much of the difference can be attributed to charger losses. Since your EV is likely much lighter than mine, I would say that about 350 Wh/mile is what you can expect for shorter (10-15 mile) charges, and perhaps 300 Wh/mile for deeper discharges, so your 305 Wh/mile number doesn't seem to be implausible, especially if you are measuring at the battery pack, and not from the wall.
