    Can someone help me calculate how much a kwH costs when you have to pay for a charging station's time?

    For example: Chargepoint stations near me cost $1/hr for the 30A j1772

    cheapest you could pay would be based on 240x30 = 7200wH @ one dollar would be 13.9 cents / kWh. It might be fed with 208v in which case you get less power and it will cost more per kWh.

    A valid comparison...

    A valid calculation if comparing to the cost of electricity at home. However, if you are using this to determine cost per mile you need to remember conversion loss. 20% + would be normal.

    Yea, i'm comparing it to cost of electricity at home. I have a crappy situation where my condo has decided to not let me install my own charger. They want to use a 3rd party company (for valid reasons), but this company charges ~55 cents per kwh AND has me paying for the charger install. It so happens that San Jose has free parking for EVs and chargepoint stations in all the overnight garages. And the closest one is 1 block away. It's not a dedicated spot, but it is a solution for the time being while I figure my parking situation out.

    remember that Chargepoint charges you for the time that you are plugged in, not necessarily time to charge.

    Not around me. The Chargepoint stations supplied by Beam in NYC have unlimited monthly charging for $98/month. http://www.beamcharging.com/beam-locations.html

    It's great for getting people not use it as a permanent parking spot.

    ChargePoint chargers think that you've unplugged once charging is done, at least on the Model S.

    Also, note on the Chargepoint.net site, if you click on Connections, Verdek EV Solution is offering free EV charging in exchange for access to your charging history. There are other offers/discounts available on that page. Regardless, nearly all the ChargePoint stations around New England are free (at least, for now).
