Please (re)read the first post. He will clearly announce when it's available.

Ditto. Awesome work. Thanks !!
That sounds great! Count me in...Ingineer said:I have updated the first post in this thread with new information and details.
At 120V, is it the case that the EVSE still provides a 16A pilot signal, but the LEAF detects the voltage and only draws 12A? Or does the Rev 2 EVSE upgrade detect the voltage and only offer a 12A pilot signal at 120V?Ingineer said:Because of the demand for this, I am going to go ahead and release this as a fixed 16 amp upgrade. It is not user-adjustable down to any lower unless you use 120v. (it runs at 12a on 120v)
That does not answer the question about the pilot signal when running from a 120 volt source. I am curious about that too. Does the rev 2 unit when plugged into a 120 volt source produce a 12 amp pilot or 16 amp pilot?DaveinOlyWA said:120 volt runs at 12 amps no matter what
MikeD said:If you don't mind answering, what mechanism is used (in both 120v and 240v operation) to limit this EVSE's current output to 12a (120v) and 16a (240v) in the Rev 2 EVSE? Obviously there is more going on than a relay to simply connect the input to the output. Perhaps it is designed to disconnect the relay if output exceeds the 12a/16a specifications?
MikeD said:mogur: Perhaps it is largely academic to ask, but how does the EVSE react if a charger tries to draw more than the current that is implied by the pilot signal?
Right - but I think the question is - is the pilot signal the same or different when the EVSE is plugged into 120V vs 240V? Or does it always send out a 16A pilot signal "knowing" that the LEAF charger will only pull 12A on 120V?Ingineer said:The LEAF's on-board charger (and all other dual-voltage EV chargers on the market) will only draw up to 12 amps from a 120v source because of the design of the charger, not because of the EVSE, the Pilot signal, or good will.
MikeD said:Ingineer: So if a future EV's on-board charger could draw 16a (instead of the current Leaf's 12a) at 120v, then your Rev 1 or 2 EVSE (and the unmodified one, for that matter) would function fine (at ~1.92kW instead of ~1.44kW at 12a) if connected to an appropriate circuit like a dedicated 120v/20a GFCI circuit.
Do you think that is likely to happen (perhaps as a selectable charger option) within the next 5 years or so? (I.e, is your middle name Oracle?!).
