Can you upgrade my upgraded EVSE?

Fri Jan 05, 2018 9:05 am

Greetings, fellow Leaf enthusiasts. I purchased a used upgraded 2013+ EVSE from another member on this site, and am totally happy with it. However, I've come to realize that the previous owner did NOT elect to upgrade to 16A L1 charging capability, and the unit tops out at 12A.

I would really like to upgrade my existing unit to be able to charge at 16A on 120V - as described on EVSEUpgrade.com. I'm willing to pay to have this work done. Unfortunately, I can not get anyone from that website to reply to my repeated emails.

Perhaps there is someone on this forum who could take my existing upgraded unit, and modify the max charging amperage on 120V from 12A ---> 16A?

Please PM me if this is something you'd be interested in doing, and what fee you would charge.

I realize there are stand-alone chargers out there that can do this for around $220 - but I'm already invested in my current upgraded EVSE and would like to find a way to make it work to meet my needs.

Thanks!
Matt

If it was upgraded by ingineer he should be able to modify it for a small fee.

AFAIK it's nothing that really needs to be "upgraded" but rather you just have to pay the $20(or is it $25??) to purchase a 20a adapter cable and then EVSEUPGRADE will send you the "unlocking" sequence to let your EVSE charge at 16a @ 120v. At least I believe thats how my EVSEupgrade'd EVSE would work, if I wanted to fork over the extra money as I already have a 20a adapter cable.

When I had the original EVSE from my 2011 upgraded after the crash, I specifically asked for it to be upgraded to the highest currents for both 120 and 208/240 volts. I said I would sign whatever disclaimers were needed, but it still came with maximum of 12 amperes at 120 volts. It is adjustable down to 6 amperes at either voltage and goes up to 20 amperes for Level 2. I believe it is the latest upgrade version of the 2011/2012 EVSE.

If I underestand correctly, the 2011/12 Leaf itself was only capable of 12A charging. My vehicle is 2013, and my EVSE is the 2013/14 version.

If that's all that is required, that would be amazing. Coincidentally, Mark from EVSE Upgrade replied to one of my emails on Friday and now we're in touch on the topic. He asked for pictures of my unit, hopefully to verify it came from them so he can send me whatever this unlocking sequence is.

My "plan B" - if my EVSE Upgrade'd unit can't be further upgraded to 16A L1 charging - is this unit I purchased which should arrive today:

https://www.amazon.com/gp/product/B077VWBCJ4/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

I would then trade/sell my upgraded unit for a stock EVSE and keep the stock Nissan EVSE at home for 12A charging and carry the 16A unit with me to work for 16A charging. This would actually be nice in a way, as I wouldn't have to constantly be unplugging/transporting/plugging-in a single EVSE. Plus, I'd have to constantly be reprogramming the charging rate on my upgraded EVSE from 16A at work down to 12A at home.

When I had my '13 EVSE upgraded back in '14 I had it upgraded to 20a L2, and assumed L1 would be 16a. Unfortunately that was not the case and it would only go up to 12a max. I called EVSEupgrade and they said all that would be required to be able to charge at 16a 120v was to purchase their 20a 120v to L6-30 adapter cable. They said they'd then give me the sequence to unlocking the 120v to 16a. Truthfully if I had known this from the beginning I would have paid the $20?? for the cable and had it included with my returned upgraded EVSE. As it was they wanted to charge another $8.95(or whatever it was, which I thought was high for such a little cable) because the cable wasn't ordered when I had my EVSE upgraded. I explained if I had known at the time it wasn't going to go up to 16a 120v I would have ordered the cable, but no one told me and their website didn't make it clear.
I wasn't too happy with how the whole thing went down and since I already had a EVSE that went up to 16a and more @ 120v, I just dropped it. Like you?? I have the opportunity to charge at work on a rather robust 20a circuit so I wanted to take advantage of as much current as I could. In the end I ended up using a EVSE where I could set the 120v charging at 18a and never had a problem. It's a dedicated outlet and I generally only charged for an hour or two max at a time and while things get warm, they never get hot nor have I ever blown a breaker.
Don't get me wrong, I was happy with the EVSEupgrade people and their quality, I just wasn't too happy about having to pay for something I already had(a 20a 120v to 240v adapter cable) and a code I should have been given with my $300 upgrade.
Let us know how it works out, if you have the L6-30 upgrade(which it sounds like you do) I believe all they'll make you do is pay for the converter cable and shipping to you(should be less than $30). I wish you luck with your other EVSE, I have one similar and it indeed charges at 16a on both 120v and 240v but note you can't dial it down. IOW plugging it into a 15a outlet will blow your breaker, for that reason I'd not have that be my only EVSE in the car as if you need to charge somewhere you only have access to 15a, you won't be able to :(
I don't believe you said, but you do have a post '12 Leaf with the 6.6kw charger don't you? If not(a S model without the charger package) you'll be limited by your car's charger to 12a @ 120v and 16a @ 240v, no matter how large a EVSE you have :)

I will be following this thread to see how it works out. I would really like to upgrade the 120-volt output of my upgraded unit to the full 20 amperes since I have a 30A twist lock receptacle on my portable generator. I was disappointed when my unit would only go up to 12 amperes after I did everything I could to make it clear that I wanted maximum output when I sent it in for original upgrade.

You could always rebuild it with OpenEVSE parts. O[penEVSE supports up to 16A on L1. The default is 12A for compatibility. I have upgraded three units so far. Nothing in the unit is reusable so you need all new parts. This is unlike an Aeroenvirement unit I did that used the original coil and contactor, In the Nissan EVSE everything is potted in epoxy.

Are you sure open EVSE maxes out on 120v? Neither my Juicebox nor 30a Chinese EVSE treats 120v any different than 240v, my Chinese EVSE can output to a maximum of 30a @ 120/240v and my Juicebox can be set up to 60?? amps, either 120 or 240v. If course most Leafs top out at 27.5a @ either 240 or 120v and the older ones top out at 16a @ 240v and 12a @ 120v. The S models without the charger package tops out at 16@ 240v but I'm not sure if they still top out at 12a @ 120v or if they also go to 16a @ 120v.....
Funny thing is my old '12 EVSEupgrade'd EVSE hooked to my '13S(with charge package) will output 20a on either 240v or 120v(not adjustable) :? EVSEupgrade offered to upgrade it again for a $100?? fee, but I thankfully declined ;)
