J1772 to NEMA 14-50 adapter
In 2010 we finally created a national EV charging standard - the J1772 connector. In order to use a legacy charger (for the Rav4EV, as an example) an adapter is needed - along with a portable charger for the car in question. Here is one fine example of an adapter that allows use of the new charging station with an "old" charger. This one is made with a custom machined inlet. The unit from ModularEVpower.
Another option using a Chinese-made inlet: tucsonev
