I suspect the EVSE will go the way of the Dodo eventually due to pricing
pressure. The auto industry (GM) put the J1772 into law to make their
expensive inductive charger competitive. Now it is hitting their profit
margin and sales numbers.

 We're already seeing the requirements being softened, it used to be that
it had to be permanently mounted to the wall and wired in. Now we have
cord-mounted level 2 EVSEs with UL approval.

The cord-mounted EVSE is interesting since it doesn't protect the user from
a shock when plugging in to the utility in pouring rain. The GFCI outlet
protects the user so the main purpose of the EVSE is now redundant.

The remaining functions can be moved vehicle side without compromising
safety.
Ground detect circuit - vehicle or coupler
Pilot circuit - Coupler
Contactors - Vehicle or coupler
Proximity - already in coupler

If the contactors and ground detect circuit moves into the vehicle then the
cord can become a dumb one with just a resistor between two pins to
indicate max power draw.

It will take some time but we'll get there.
