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

Sat Feb 12, 2011 8:14 am

This morning I found that, in one of my listserves, a fellow EV advocate "Phil" posted this message:
The Nissan Leaf ships with an 120V 12A portable EVSE for "on the go" charging. I just completed designing and testing an upgrade to it that allows 240V charging while still retaining the 120V capability. This means you can use the supplied EVSE at home without needing to install an (expensive) additional unit and still have a reasonable charge rate. (over 2.8kW) The full safety features including the GFCI protection are still 100% functional, and the unit automatically switches voltage.

We will be offering an upgrade service for these to Leaf owners soon. It would be nice to gauge interest from current and future Leaf owners. Please contact me off-list for more info.

Here's the modified unit charging at 240V 12A:

This shows the new L6-20P 240V/20A NEMA twist-lock installed, along with an adaptor cable so you can still charge at 120V:

Since he is asking for feedback to gauge interest, and since I know many of our forum members would want to respond, I don't think he would mind if I shared his announcement here. As you can see in the photo labels above, his e-mail address is:

Can he post some pictures and results of his modified unit charging a leaf successfully at 240v?

I am really hoping "Phil" will offer the mod as a reasonably priced kit so I can do the mod myself. I really don't want to be without my EVSE for any length of time if I can avoid it and I see no point in shipping the unit back and forth if I can do the work myself.

I am a little skeptical. I would want to know that the input voltage and current are being passed through. I could easily allow for a dual voltage input, but the output would remain the same. I would also want to know that the car would accept the full capacity of the updated voltage and current without a negative effect. I want to see a video of this "in action".

For home charging I am considering purchasing a European L1 and just converting the plug to a US 240v.

4/8/11 update. I remove my skepticism. Great work!

i am very interested but concerned over the logistics of this.

does it require that i send in my unit? if so, that would be a hassle since its the only charge option i have.

i *could* go without since i still have my 2006 Prius, but that would be torture. as much as i loved my Prius before...since the Leafs arrival, the love has tarnished... A LOT.

This is pretty awesome. He must have found an auto-ranging power supply that properly fits in the case! Hopefully I can just pick up the power supply from him (I already have the L6-20 plugs) :D.

Please stay tuned for details. To answer a few questions:

No kit available as of now
Unit will need to be sent in but that could change, but turn around is quick
Current is the same over each voltage and unit is tested at 240
Price TBD
Unit will be tested by a forum member here next week so you will receive his real-world feedback soon


Let me know if you have any other questions.
