For USB sure.... I'm pretty sure this doesn't charge over USB.

I'm surprised, and you'll be surprised, but this is true!! I gotta start actually looking shit up before saying something....

		J1772 is significantly more than a single resistor. And, while the signaling is analog, all practical implementations are going to use digital circuitry to generate and detect it.
