Re: Nissan L1 EVSE third-party upgrade to both 120V and 240V

The PowerGrip Plug with the nice handle is not even very expensive.
I wonder if they have a whole series of these?

LOL! You guys. I was regaling others about my building an AC-DC adapter for my tape recorder, without actually using a transformer to get me from 240v to 12v AND using a metal headphone jack. Now that was only UK household current, so 13A, but it still tingled a tiny bit when I went to go plug the jack into the recorder! Ah, the innocence of youth! :D

Sometimes I wonder if the actual driving of the car is actually more dangerous than the electricity used to charge it... ;)

I call FUD on the dangers of the 240v outlet connectors. If that concerned buy one with a cover.

1. Motor vehicle crashes 43,200
2. Falls 14,900
3. Poisoning by solids and liquids 8,600
4. Drowning 4,000
5. Fires and burns 3,700
6. Suffocation 3,300
7. Firearms 1,500
8. Poisoning by gases 700
9. Medical & Surgical Complications and Misadventures 500
10. Machinery 350

wiki says about 550 electrocutions in 1991 in the US. It would seem to me far more dangerous to ride in the car.

So for those who don't already realize it, this is my L1 EVSE we modified here, and I am very much looking forward to getting it back and testing it over the next few days. :D

For those of you concerned about turn-around time....all told, my unit will have been away for just 7 days. Now I'm not saying that's how long it will take to modify any further units, but I think that's pretty good going considering mine had to be thoroughly examined before any reingineering could take place.

Will you be able to open your EVSE when you get it back, or will it be glued shut or "forbidden"?

As part of your deal with them, are they providing you with any information about what they found and/or what they have done?

Will you have it at the Gathering on the 19th Feb. in Santa Ana?

The Leaf EVSE doesn't meet official J1772-2010 spec because it still enables charge even without the presence of the diode. In reality this isn't a big deal, as the diode is designed to prevent power in the event of a low resistance short. Such a short could be caused by dropping the charge plug in a muddy puddle which just happens to have the resistance needed to trick the pilot into charge. The lack of a diode in this puddle would fail to start the charge if the EVSE met official spec. However, the GFCI protection would trip in any event thus rendering the hazard inert.

As Panasonic originally shipped it, the EVSE has been resealed from the weather. The user may open the unit but should there be an issue and the unit has been opened it would void the upgrade warranty and would be unsupported.

That's really interesting! Doesn't the J1772 document specifically call out the diode being required for this exact reason?!

I agree that it isn't a big deal, but when you have industry groups running around saying that J1772 is three laws safe ;), you would think they would cross their T's and dot their I's (or i's)...
