Nissan Leaf EVSE upgrade - Reviews? Reliable?

Fri Aug 22, 2014 1:10 am

Hi,

New to the EV scene. I am looking to charge faster than the standard 110v supply that came with my 2013 Nissan Leaf.

Just wondering will the EVSE upgrade to the existing 2013 Nissan supplied 110v EVSE to make it 220v capable work as good,better, or worse, than say a wall mounted level 2 EVSE such as the Siemens?

The upgrade costs $287, while a new Siemens Level 2 will cost me $600.
Will it get the same result?

As I have a number of other EV projects at home so cutting costs would be great if possible.

I can't provide actual comparison experience. However I can say I chose to do the EVSE upgrade and am very happy with my decision. It is capable of charging as fast as the car can handle (so yes, same as wall mounted Level 2) and seems to do so quite well. I opted for the adapters so that I could plug into just about any plug out there - but so far have only used my 240v plug.

I like that it is more portable in case I ever want to plug in elsewhere, but have yet to have a need to do this. Having the standard 14-50 plug installed in my garage was easy enough (electrician did it) - no need to really get into EVSE discussion with him so it was a quick normal job (no special knowledge/skill required to do it). I believe that helped to keep the cost of install down (even with professional doing the job).

So, my opinion is that a more permanent mount EVSE really is unnecessary for my home use. IF I were to plan on sharing with others (or had other vehicles of my own) then perhaps it could make a difference.

Other things to consider is that some other EVSEs out there can do fancy things like meter the power or turn on/off at scheduled times. While nice, I didn't consider these necessary for my use. Not all can do these things so if you need/desire them read the details...

Getting something like the Sieman's unit isn't necessary to get faster charging. I would advice you to get the upgraded EVSE! I have had mine for more than 18 months and it has worked flawlessly! it will charge the car way faster than the L1 that came with the car, it will be money well spent.

At home I prefer a wall mounted unit. And my upgraded EVSE worked perfectly also.

I agree that the EVSE Upgrade for the 2013 SV works great and can deliver VERY CLOSE to full 6.6kW charging capability. I think it's 5.8kW. It will charge you from nearly empty to full in less than 5 hours, the longest it has ever taken my car to charge was 4hrs and change. The upgrade and certified electrician listed on Angie's List wiring were money well spent. Oh, and I have been using my upgraded EVSE for more than a year. My only complaint might be the twisting of the cord, but there's probably a method discussed on this forum to help keep the cord looking prettier... I just don't care enough to bother. I hope these posts have helped! :)
OOps... My bad... Thank you. Yes, it will deliver 4.8kW, not 5.8.kW

The EVSE upgrade will only provide 4.8kW to the charger. This will provide around 4.3kW to the batteries.
For full 6.0kW charge rate, you need a 40A circuit.

I say get both. The advantage of the wall unit is that it will allow the car to charge at its maximum rate of approx 6.6 kw, while the evse upgrade unit will only do 4.8 kw. Plus I think it looks better in a permanent installation than a device that is meant to be portable. The difference in charging power usually is not a big deal, but sometimes you want to get a quick charge after work so you can do errands later, and in that case it makes a big difference. The advantage of the evse upgrade is that it's portable, it's cheaper, and most importantly you are able to adjust how much current it draws. That is very helpful when you are charging in a strange location away from home. As well as it supports 120 volt charging up to 16 amps if you buy the 5-20 adapter. The advantage of having both is a biggie. You get the advantages of both, plus you have a backup in case one of them breaks. I'd say either unit is as reliable as the other.

Of course, there are portable solutions that will also provide up to the 6.6kW / 30 amps (or more) that a Nissan LEAF requires:

I went with the Siemens wall mount personally. I've debated about getting my portable upgraded, but I really never use it. Would be nice in an emergency though... I will consider it. For now, I'm happy with my wall mounted unit :)

My solution was an OpenEVSE built by GlennD here on MNL for 425+shipping - Built in future proofing, adjustable capacity to 50A in 2A increments, multiple plug options if I need them, 120V or 240V, mounts on the wall or portable. I love being able to charge at 27.5 amps. An hour gets me more than 30% of recharge capacity, which is great when I come home for lunch.

I have the OEM trickle charger in the car. Not really for emergencies, but to just store it there. I can't ever see using it. If I am out and about and need a charger I will stop at a L2. I guess if there are no L2's then I would use it (but will probably call for a tow rather than charge at 5% an hour for half a day).
