My garage does have electrical (110V) but not 240 volts required for n EVSE. In fact, I do not believe it has a ground because I plugged in the trickle charger cable and the lights on the unit started flashing. When I investigated, this seems to indicate no ground. When I plugged into an outlet with a known ground, the lights did not flash.

I have another related question.

My first quote to have an EVSE installed in garage came back at $2800 which is way more than I'd like to spend. I have a detached garage so the buried cable increased the cost.
...

Could you do the trenching yourself and lower that price? Perhaps hire some cheap labor to get it done?


The electrician actually asked me if I wanted to do it myself. I said no because I wouldn't know how to do it, nor would I have the strength even if I did know how to do it. There are also complications that likely contributed to increasing the cost such as moving a slab of cememt, and trenching around a tree with roots.

So I'm going to pursue plan B and just have an outlet installed on the outside of my home to eliminate the trenching and any work inside the garage.

Good idea, but I'm not so sure about a plug outside. I personally would hard wire in that case.

Given the expense and complexity of a higher power charger ... crazy question, do you really need one?

If you could fix the grounding issue with the garage 120V outlet, could you get by with L1? I've actually been using L1 almost exclusively for the last 2 months (I have an L2 in the garage, but it's hard to get to ... long story) ;) I do have a quick charger in the neighborhood if I outstrip my L1 charging ability. But at ~30 miles per day on average, I was fine with L1 charging.

(Nissan does seem to recommend that the L1 charger be used only on a 120V circuit which has been validated to be able to handle the continuous load, but that might be a lot cheaper than the higher power install you're looking at).

Living in MN you might have been able to get by this summer with L1 only......but winter is an entirely different animal for an EV :) I also got by all summer and through December but by January, I cried uncle and got my first L2. The thing is even with only a 30 mile commute, in the bitter cold and snow you may only see 35-40 miles range, and thats with a 12 bar battery. 30 miles would be doable in all conditions, assuming you have at least a 11 or 12 bar battery but the problem becomes when to charge. To completely fill your battery you'd need to be plugged in 20+hrs/day, doesn't leave a lot of time to drive and you'd have to have access to a quality 120v outlet almost all the time.
My first L2 was a 40a Juicebox and it made all the difference in the world. No longer did I have to constantly look for places to plug in, in a little more than 3hrs I could go from almost empty to full! Another big plus with L2 is pre-heating your car. With L1 you actually lose charge preheating, even if plugged in. You lose almost a percent every 2 minutes in very cold temps, 30 minutes of preheating and you could be down 15%, which means you'd be starting your day at 85% instead of 100%, not so great if you need every percent. With ~18a L2 you break even using morning warmup, with 27.5a(or the max a Leaf will take) you can actually full preheat and gain about 10%/hr, very nice indeed. With 27.5a not preheating you gain ~30%/hr, again in ~3hrs you can basically fully charge your car. Much better than the 20+hrs using the OEM L1 EVSE.

Living in a much warmer climate is a different story, there you might be able to get by with just L1 and be quite happy :)

If I were the OP I'd just go with the outside house outlet, people do it all the time with RVs and don't seem to have an issue. Personally I went with either a L14-30 or L6-30 outlet for my outside outlets but then your limited to ~24a L2, you need a 14-50 outlet(which is a fair amount larger and what most RVs use) to be able to pull 30a continuous.
Note it is possible to find 14-50 extension cords, they aren't cheap($100+ for a 20' model) and they are quite thick, but still cheaper than $2800. Note personally I would not run an extension cord where you mow or over a sidewalk, but thats just me. I guess if you coil it up when not in use it might be OK, thats the OPs call.

Well, that's a good point, I don't think the L1 even keeps up with the cabin preheat load.
Here in MN, we try to forget about the winter until it is upon us. :D

I bought the juicebox. It is worth it if you will use the wifi features. When it is cold outside, I can look at my phone and know for sure I plugged in and it is charging without getting out of bed.

Yes the Dipsoda and similar 16a L2 EVSEs are quite a bargain but note in a very cold climate the 16a may not be enough to stop a slowly discharging battery using preheat. I've noticed I need ~19a @240v to not slowly discharge my battery during a 1/2hr morning warmup. If your OK with not starting out with a 100% charge in extreme cold temps, your fine, if you need every % I might suggest a 20+ amp L2 EVSE on at least a 30a circuit. I have a 20a L2 EVSE and I still start out with a 100%(or 80% if I have this enabled) charge even on the coldest mornings using morning warm up.

I recommend a 14-50 four-wire receptacle in a weatherproof box supplied from a 50-ampere breaker (savings in wire for 40-ampere circuit would be minimal) so that you have a full capacity RV receptacle with neutral that gives future flexibility. I also strongly recommend that you have the electrician check out (and repair) the 120-volt circuits in you detached garage for safety. UL listed plug-connected EVSEs have supply cords not exceeding 12 inches long so you need to have the EVSE on hand and determine desired mounting location before having the receptacle installed.

As far as EVSE recommendations, good advice has been given in earlier posts. I have an Aerovironment 30-ampere unit at home that has been in continuous use since June 2011 (designed to be hard wired on a 40-ampere circuit), a Clipper Creek 40-ampere unit with 14-50 plug for use on a 50-ampere RV circuit at my workshop/garage, and a coup!e of EVSE Upgrade Nissan units (one 12-ampere fixed and one 20-ampere adjustable, both 120/240-volt with twist lock plugs) for portable/backup use. All are quality units and I recommend any of them.
