Clarifies that the inverter is NOT part of the PDU. However, the inverter doesn't appear to be required to be swapped out in the 2015 model for the upgrade since it only "Converts direct-current electricity to alternate current when driving, utilizing the motor, and then recovers energy by converting alternate current to direct current during deceleration (regeneration)."

Further since it is below the PDU, it shouldn't have to be removed.

Do I need to change the software after replacing the upper unit and installing the harness with the charging slot?

I have a 2014 Nissan Leaf S. It did not come with the CHAdeMO DC quick charge port and only charged at the 3.3kW rate. However after doing some research I found it was possible to upgrade my OBC to a stock 6.6kW charger. I have since done so using a salvage 6.6kW charger I ordered online. No software update was required. It took approximately 7 hours to remove the original stock charger and replace it with the higher power one. The operation was pretty straight forward. The only issue I have is I don't (yet) have the CHAdeMO port but it should be pretty simple to add one.

So the simple answer is YES it can be done at least on the later models 2013+. I've seen one other person who has done this and posted detailed instructions online. If anyone is interested I can try to dig up the forum where the procedure is explained in detail with pictures etc...

I've found a great deal on a 2015 SV but it doesn't have quick charge, which is mandatory for me, so I might buy it for $2500 less than the best deal I've found on one with quick charge, and add it myself. I'm undeterred by a day of DIY installing salvage yard parts but would like to hear from someone who has already done this. All info appreciated. Thanks.

I have a 2012 Leaf with the 3.3kw (240 vac) charger. I wonder if the 6.6kw charger can be easily swapped in this model year? Anyone done that successfully? I don't believe this subject is related to the QC (CHAdeMO) charge system - however, it would certainly shorten my charge times to 1/2 current. I already have the 30 amp circuit and controller (OpenEVSE).
Appreciate any help on this one.

You might want to look at the Brusa Charger installation topic.

PLEASE don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

Leftie;
I recall I did - $$$'s. A salvaged OEM charger, plus the fun of installing 8-)

I would love if you could dig that up. I haven't been able to find the correct wiring harness for the QC.

See http://www.mynissanleaf.com/viewtopic.php?f=37&t=21106. Lots of useful information on doing the swap there. I know I saw this done on another site too but can't seem to find it now.

I got a good deal on a CHAdeMO port and installed it. I still need to connect the logic lines (pins 1-4 & 7-10) of the CHAdeMO port since my Leaf S does not have the correct wiring harness. It should be possible to run some wire to the VCM or OBC to connect these lines without replacing the whole wiring harness. I just need to know what CHAdeMO pin goes to what VCM/OBC connector pin...

I know this thread is dead but I wanted to post an update just in case someone else comes across this.

Yes, it is possible to install a QC port on your Nissan Leaf if it did not originally come with it. I just finished my conversion today and charged at a CVS using the DC QC charger. It charged just fine no issues.

To do this mod you'll need at least these two manuals:

EVC - EV CONTROL SYSTEM
VC - VEHICLE CHARGING SYSTEM

If you look hard you can probably find these online for free. I know the Nico club had them but they no longer allow you to download.

You'll also need to be handy with a soldering iron and be able to read schematics...

What I did:
I got a used 6.6KW charger and used QC port. The prices for the two wire harnesses were a bit more then I wanted to pay so I wired it external to the harness. I got some connectors, 9 conductor wire, a relay and fuse. I opened the OBC (PDM) and connected the QC port with the 9 conductor wire. There is a vent hole near the rear bottom rear of the the charger. I removed the filter and fit the wire in snugly. The filter was then relocated to the back of the cover. I had to drill a new hole. PDM Pin 9 also needs to be run into the 9 conductor wire so it can be connected to the relay.

Since the wire harness does not include pin 8 for the VCM I had to carefully open it and solder a wire to the pin 8 on the VCM. There is a plugged hold in the fire wall conveniently located near the VCM to run the wire from pin 8 under the hood to the relay. The VCM is located behind the glove box. Pin 5 of the VCM is routed to fuse box IPDM Pin 55 (light grey wire). The last wire (12v) is in another fuse box. I don't have it's ID right now but it's next to the battery. This fuse box will have fuse #33 missing. One connection was there waiting for the fuse. One connection was missing. The missing connection is here the last wire was installed with the fuse.

I hope this helps. I typed this fast and from memory so it may not be clear but I hope it is clear enough you give someone the clues they need to do this themselves. I think I'm the first person to pull this off as I have not found anyone else on the internet that has gotten a QC port working. I tucked everything nicely using zip-ties and if you didn't know you would assume the car was stock.
