Since there's so much discussion on the CHAdeMO adapter, I decided to post a new thread about a possible SAE J1772 DC (Combo) adapter for the Model S. First thing to point out is what the socket and connector looks like: The top two are the socket and connector for J1772 DC. The bottom two are the socket and connector for J1772 AC. The bottom right J1772 AC connector can plug into the top left J1772 DC socket The top left J1772 DC connector can NOT plug into the bottom left J1772 AC socket because of the plastic slot pointed out by the red arrows. This extra plastic slot is also why the existing J1772 to Model S adapter will not directly work with the new J1772 DC connector. Next thing to understand is that there are two DC modes: DC Level 1 - uses only the top J1772 AC half of the socket and provides up to [email protected] DC Level 2 - uses the bottom two extra large DC pins and provides up to [email protected] A recent presentation by the SAE confirms a Supercharger to SAE DC Level 1 adapter can be made for less than $100! It'll basically be exactly the same as the current J1772 adapter except modifying the plastic slot previously mentioned. http://www.sae.org/events/gim/presen...rds_status.pdf Making an SAE DC Level 2 adapter will be a bigger challenge since there needs to be a connection to the two large DC pins on the bottom from the two large pins in the top of the Model S connector.
