> "the difficulty would be apportioning the metering as we didn't have allocated parking spaces" There are already various technical solutions to this. Most chargers now days are "connected" - ie have a WiFi chip or cellular modem built in to the charging unit. Identification/billing can be apportioned via a RFID card or app interface. In future, "Plug & Charge" will make it possible for the vehicles to securely identify themselves to the charger for automatic billing, doing away with the need for an app or RFID. If cost of the chargers is an issue (ie you want a large number of outlets but it's initially split between only a few EV owners who are willing to pay for them), then consider something like Ubitricity (ubitricity.com) where the outlets are "dumb" and the billing smarts are built into the cable which EV owners purchase.
