Is it sufficient to just tap the Proximity, Pilot and Output pins into a CCS socket? I know that it might be limited to 7 kw CCS.

Doesn\'t your Leaf already have a J1772 connector. What would be different?

Some sites are CCS only, no J1772. I still need the OBC for signalling and CAN, but by-passing the AC-DC.

I thought the J1772 was a part of the CCS connector. I guess it\'s just not usable separately. That sucks. I thought about buying a Leaf in Puerto Rico, but the Chademo(CDM) connector put me off. It put the salesman off too. He didn\'t know what it was for.
I don\'t think the island has an Chademo chargers,
Probably not many CCS chargers either.
so I guess that\'s not unexpected. I had to explain to him about fast DC charging. He only knew about the J1772. He also didn\'t expect to sell the car any time soon. Nissan made them take it.
My Leaf will have J1772, CDM and CCS.

CCS plug will not fit in the J1772 socket. There is no AC supply on the J1772 part of the CCS, the AC pins are unused, but two additional DC pins. I always think that\'s a bad physical design.
You can:
A. External DC (400V) to AC (220V) converter into J1772, no internal mod to vehicle.
B. Tap into X and P, using existing C.
C. Tap into X, using existing C, custom P
D. Full custom X, P and C
If adding the CCS socket is all it take, then it\'s easy to do, at least for dumb 7kw. Eventually, i can monitor the battery voltage and translate the pilot signal for higher power.
Furthermore, DC is easier to implement for storage buffered fast charger, and transfer the DC-AC cooling to the station, rather than the vehicle. In fact, if all i do is CCS and CDM, i can probably disable the cooling system. I have no cooling on the main batteries, and my expansion batteries and booster/inverter are A/C air cooled inside the passenger compartment.

Opened up the OBC just to take a look. I didn\'t want to disconnect the cooling hosts (from under the car), but they made it difficult. First of all, needed to order a T35 security torx (w/ hole) and had to get the other 13 sizes as well. Needed to hammer the torx bit into the screw, but the lower one sit right next to the seat bell mounting bump and impossible to hammer. Had to loosen all bolts and jack it up with a 2x4.
Hooked up 1K to 12V and Pilot, 150 to promiXity and ground. The car beeped, but no charging. I guess the OBC needs power from the AC pins, or to hack the circuit board with 12V supply and regulators.
Better to look around for another new ($1500) or used ($400) OBC to play with.
