Ken - there are lots of websites and apps available that show this. Many of these sources would have overlapping charging stations. To name a few - Coulomb (mychargepoint.net), PlugShare app, Charge locator app, the DOE website, EV charger news, etc.
For PlugShare, you can enter your house if you offer it as a charging point, even if it is only Level I. I'm registered for Level I and Level II charging on this. They also have a website (PlugShare.com).
By the way, does anyone have a 'reverse' adaptor for J1772? That is, you have a Nissan Leaf, but the charging station is a 220V AC 50 amp RV outlet, found at RV parks. How can a Leaf owner take advantage of this to charge up the car?
