Go to http://database.ul.com/cgi-bin/XYV/cgif ... tsrch.html
In the "Category Selection" use "Electric Vehicle Plugs, Receptacles and Couplers".
Click "Search". Seven Results. The Yazaki result (for example) shows the 30A limit. BMW shows a higher limit (60A), but others for L2 also show 30A.
Also, on the http://evsolutions.avinc.com/products/
page (and the Coulomb products page) just about everything is shown with a 30A limit, i.e. conforming to the UL listing.
Thanks. I've not been able to find any UL entries for the current J1772 products. That suggests that the entries in the database might be for the last generation of J1772 hardware.
I've also not been able to cross-reference the part numbers listed in the UL database to confirm or deny what products have the 30A limit. (For example - the Yazaki part numbers.)
I agree completely that the datasheets from AeroVironment, Coulomb, etc. show 30A for their L2 units. It's clear, though, that the connector themselves have to support up to the 80A continuous rating per J1772. The connectors have to be up to the task even if a particular EVSE manufacturer chooses to build an interface with a lower rating.
Back to the 30A, though -- we're talking about 30A into the car, though, and 30A at 220V is still enough to support both a 3.3kW and 6.6kW on-board charger.
