How about setting up a 1-900 line for customer support or inquiries?.. its a common practice in Europe.

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

Now that I finally have a "week of May 2" on the dashboard, I have a few questions arising from earlier thread comments.

I would like to use the modified EVSE as my sole charging method, other than Public infrastructure, which, given my Shasta County California location, is likely to be minimal.

My best bet for local charging likely will be RV resorts. Is the "L6-20 receptacle" the RV standard?

I can then buy the adapter cord, and install the same receptacle in my garage and carport.

If I understand correctly, the "quick220":

Will not work in GFI outlets. I would like to get it to charge and friends and acquaintances homes and businesses, but haven't codes required all exterior outlets to be GFI for some time now? Just how useful has anyone found the "quick220" to be in practice?

Any results noted as to charging efficiency of using the modified EVSE in L1 as opposed to L2 mode? Any reason to expect any difference?

Any other suggestions?

I got my Quick220 couple days ago (Package P-102):

Pretty nifty.
My wife might even start using the Quick220 as her power source for an electric kiln she has for her ceramic studio (in garage).

I expect to receive a modified L1/L2 EVSE today from Phil.
edtoakrun: give me a few days and I will report back how useful the A220-20L is along with the modified L1/L2 EVSE.
For now, I expect to be using the combination daily as my primary source of L2 charging for the Leaf.

Correct that the Quick220 will not work in GFCI outlets. The way GFCI works is by comparing the current through the "hot" leg vs. the current through the "neutral" leg and opening the circuit if they don't equal. When using a Quick220, your only utilizing the "hot" leg from each outlet and not using the "neutral" at all, so this will cause an immediate imbalance.

I've been checking out various 120 volt outlets in my area and all the outdoor ones I've ran into have all been GFCI. Even the ones at parks and other recreation sites seem to have been upgraded to GFCI as well.

Regarding the charging efficiency, I doubt you'll be able to tell any real difference between 120/240 volt charging. Since nobody has taken apart the Nissan charger yet, we don't know for sure what the efficiencies are yet, but once we can start pulling the SOC from the OBD port we'll be able to make some educated guesses.

Interestingly, new electrical code requires either GFCI or AFCI on all circuits; the "Quick 220" will be unusable in a house like this. The good news is that any houses that comply with the new code will likely have 240v available from a range or dryer.

A "Quick220" will work properly on AFCI. IIRC the code only requires AFCI in bedrooms currently.

Garages/kitchens should still be a good source of non-GFCI power.

Based on what I've read, the most common plugs at RV parks are the NEMA 6-50 and the NEMA 14-50. but i haven't actually driven around conducting my own survey so I can't say for sure.

See my sig if you want to buy some adapters. :)

Most AFCI breakers include GF detection (at a higher level than the 5ma GFCI threshold). There is one manufacturer who recently came out with AFCI breakers that don't include GF detection, which is very convenient if you need to AFCI protect an MWBC. Sorry forget the name but I bet it can be found on Google.

Ingineer wrote:IIRC the code only requires AFCI in bedrooms currently.

That was the 2002 NEC. Under the 2008 NEC, effective in CA since January 1, 2011, most residential 120V 15A/20A receptacles are to be AFCI protected (excluding kitchen, bathrooms and a few other things).

Ingineer wrote:Garages/kitchens should still be a good source of non-GFCI power.

Kitchen, maybe, for the non-countertop receptacles (e.g. disconnect the garbage disposal, or microwave/hood or whatever). Otherwise, kitchen and garage receptacles are to be GFCI protected.

Phil told me that the modded L1 EVSE actually runs more efficiently on 240V. I did a 20 kWh charge in 8.5 hrs and the warmest spots on the modded EVSE were the Ready & Charging lights. :^)

Geek, are you sure that you saw a 6-50 at an RV park? I suspect you saw a TT-30; a 120v 30amp connector that is useless for Phil's mod.

Just curious if 6-50s are more common than I thought...
