I just learned two interesting facts about J1772 today. My employer is about to upgrade our 3 Level 1 outlets (120V/20A) to 2 dual-plug ChargePoint CT4000 stations. This will increase our charging capability from Level 1 to 7.2kW Level 2 and increase the number of charging cars to 4. Great news so far. The Leaf owners will be ecstatic.
The first thing I learned is that latest-technology EVSEs ONLY support J1772. There is no support for 120V outlets in the station. Unfortunately, we have several early adopters that don't have J1772 ports. These include my conversion, a Solectria Force with a Zivan charger, and a couple of electric motorcycles. Since the old outlets are being removed to put in the new stations, we have to do something. The second thing I learned is that I am suddenly WAY more interested in a J1772 adapter than I used to be! Since my charger is dual-voltage, I at least have the option of doing an adapter. Some of the other vehicles will be much more difficult. Since I have a twistlock receptacle (NEMA L6-30P) under my gas flap, and already have 220V-twistlock and 110V-twistlock adapter cords, I'm looking for a J1772 to twistlock adapter. I don't think such a thing exists, so I will probably have to make my own. I don't really feel like converting my car and all my pigtails to J1772-compatible. Call me lazy. And cheap. I also don't feel bad about connecting J1772 to my twistlock connector since it is rated for 250V/30A. I've seen discussion on the list for Rush Doughterty's adapter box and/or bare J1772 socket. That sounds like it could work and I could then wire that to a female twistlock connector. Other thoughts on how to get J1772 support into a conversion? My charger is an Elcon 2000+, so I'm never going to get the benefit of the J1772. I will be drawing about 10A on the 220V line.
