I did this upgrade on my 2015 model EVSE this weekend. I used a 25' generator power cord from home depot with L14-20 connectors which was close out priced at $14. I cut the female end off with about 1 foot of cable to make an RV adapter with a 14-50 plug. Cut a few more 1 foot sections for more adapters. I used some thermistors that I had from old laptop battery packs to replace the thermistor in the original plug (yellow wires) and put one of them near the red wire splice. With the cover still off I plugged it in and charged my car. I used a IR thermometer to see if any of the new connections were hot and they were not.

This upgrade is sufficient to fully charge overnight, which the L1 charging does not do. I can still choose to use free public charging that is about a mile walk from work, but I no longer have to.

Good Job!!

Looks like this mod has helped quite a few folks now. I am a happy user for over 2 years and many many charges. I have 23K miles on my vehicle now. Never needed to go bigger than 12A and 240V so far. I am told charging at the slow rate may be helping my batteries from not losing their capacity. So far I haven't lost a single bar!!.

Cheers!

I really like this thread and how some very intelligent people have improved on this modification of a very simple pass through device that Nissan provided.
But some seem to think the leaf operates with 240vac input. When rather its 120vac inputs.
And the Nissan provided adaptor designed with components that directs multiple voltage legs at or about 120vac very basic.
I look at the mod coming out of CA for 300+$ as a friend has one so I dissected it with him with a time clock running. After showing him the differences, he understood the labor rates and component list.

I plan to make adjustment to my adaptor and build separate plug adaptor to bring single phase neutral back in.

Buts let's face it.. You could do the same with two 20ft long 8awg wires and get the same results, but the Nissan box looks nicer.

And yes I am and then some.

Pray tell us the difference and the results of that dissection.

No. What it is, is what it is.

Happy to report.. 25K miles done and almost 3 years of ownership. I have used this mod right from the beginning and have not had an issue at all. It has been in rain, dropped many times and is till robust and has shown no signs of any problems. I have to guess that I must have charge the car over 1000 times by now. Whether just topping off from 70% to 100% or going from as low as 19% to 100%, this EVSE mod has never had any issues and nothing has ever over heated. This EVSE has been used in Northern California Bay Area weather which ranges from 95F to 32F.

Cheers!! PM if you have any questions!!
