If EV enthusiasts don't care that their range extender is fuel inefficient by design, then that kinda makes the point
re: SAE J1772 that is good news. Of course I start thinking of all kinds of "improvements", i.e. if the charging stations could dynamically control the current and voltage based on feedback from the car (based on voltage/current feedback from the charger) then it would mean less circuitry needed in every car, just a $3 microcontroller that controls the charge profile instead of power circuitry, and it could have a unique identifier so they know which account to draw the funds from if it is a pay service.
And having driven off with the gas pump attached once, I am glad they thought of a proximity switch. But it does kinda kill this as a standard for battery trailer/on the go electrical source, even if you make a streamlined right angle J1772 connector.
