It may drain the 12 volt battery if done for enough hours. I'm not entirely sure that the car can detect the EVSE if the latter isn't plugged in, but it may take nothing more than having it plugged into the charging port. Or it may not...


Ahh. Makes sense. Well. It’s only 6 steps out the door so no real excuse not to just plug it in.
Thanks again.

8A will work fine but why. The spec says 6A max but why. The car can take whole lot more. 8Aa is just to p protect poor 120VAV wiring.

Its just a timing thing. Timing it to be full just before I hit the road. Honestly most of the time it will be on 12 amps. We charge 2 or 3 times a week. When we need to charge fast we use the Juice box.

Does your LEAF have built-in timer? If so then you can program an "end-time only" timer that does that. Sorry I don't know what the "SE" trim level means for Canadian LEAFs.
I noticed you're still working with polymers.

There's no such thing as an SE trim for Canada. See specs tab of http://nissannews.com/en-CA/nissan/cana ... -press-kit.

YAh. That’s a typo. It’s an SV.

Our EVSE is on a heavy duty "time of use" contactor that shuts off when it hits the high rate and turns on at the low rate (the utility can also load shed and shut it off if they want). A lot of times I will get home and plug it in and it will start charging and then hit the on peak time and the evse is essentially "unplugged" and the can sits for a bit waiting and goes to sleep. If you don't change anything once the EVSE gets power again it will wake up the car and start to charge again, I have done this many times with no issues so far. I also often come home and plug in during the on peak time and once we hit the off peak the car will just start charging. I have never had any faults or warnings from the car doing this.

As was mentioned a regular light switch shutting off with the EVSE load on probably isn't the best for the switch, but being only 8 amps I don't think it is a safety issue, it may just wear out that switch sooner. You could swap that switch with a heavy duty 20a one if it does fail.

I'd also advise against flipping the switch during charging, probably not good for your switch at all. Other than being quite inefficient I don't see any problem charging at 8a @ 120v, just slow as heck :D

Yes the fault should go away as soon as power is re-applied.


Yah. The coiled cable works well in this situation. The black button (hard to see) switches between 8 and 12 amps. I hose clamped it to the board and screwed the board to the wall. Need to repaint the board yet but it looks pretty good and isn’t visible from the street.


Mercedes supplies a Lear EVSE that comes with a coiled cable but the Lear has a poor reputation for reliability.

Well, the smart is a Mercedes product so it’s probably the same one. We haven’t had any problems in the three years we have had it. Either with the EVSE or the car.

My stock EVSE is in a sealed bag. I have an OpenEVSE unit as carry along. I will turn in the stock EVSE at lease turn in. I could set the EVST to 16A for a 20A circuit. But why bother. I carry it along for an emergency but I really do not plan to use it. .

M old OpenEVSE had a bad 120V adapter but since I never used the EVSE I did not notice.

I am sure that some are happy with L1 charging but I am not that person. For Me I charge at L2 240VAC and 40A. That fits my needs.

Quick Charge Power has a L3 adapter but I really do not need the added range and shorter charging time. For me 40A at 240. If I traveled to San Diego it would make sense.. It is priced similar to Tesla" Super Cahrge's rates.

But for most Mercedes owners that is pocket change. I think the whole adapter is 3K plus install.
