What year pdm? My van has a 2017 AZE0 from a 30kWh Leaf and the pictures below are from a 2015 24kWh.

If you can’t tiger the dcfc contactors externally then you’ll need to hardwire them unfortunately


I've come to that conclusion as well. So in preparation I lifted the lid on my spare AZE0 ...

I confirmed today that the quick charge contactors are not closing when I power pin 2 with 12 volts and earth pin 10.

What is required to close the contactors in the PDM? I suppose I could brute force it by wiring directly to the contactors but I'd rather not.

I looked again at how the Leaf PDM is wired to the Chademo socket and changed around PDM pins 20-22 as per this diagram.

Sadly still no charge. I suspect the quick charge contactors aren't closing. Can someone ...

I know this is an old thread but the topic is relevant to my situation. I'm trying to get Chademo working on my van. I'm using a full Leaf stack from a 30kWh AZE0. The wiring is shown below.

I want the sound of a horse trotting as my sound generator. It's on my to-do list but quite close to the bottom.

I couldn't get the online tool to connect to my display but flashing it with my linux laptop, with the command below, worked a treat!

This is what I get when I try and build from source.

Is there a way to provisionally edit a subject on a closed post that would then get moderator approval?

A bit more info, when I go to 192.168.4.1/update I can do OTA updates but none of the above files fix the "No SPIFFS Files" error. I had a look at the terminal output, shown below and noticed several warnings.

PXL_20260301_170540547.jpg It's long overdue for an update. I got the van on the road at the beginning of March and has done over 800kms so far (my dash is stuck in km, one of these days I'll figure out how to switch it to miles! :D). It still has some electrical gremlins to chase down. The problem ...

As Tom says draw a diagram, then post it on here so we can see what is going on.

Are you using the service plug from the Leaf pack and is it fitted correctly?

Is this of any help?

The ZV supports the Nissan Leaf battery pack. The Leaf PDM is also supported but I'm not sure how easy it is to implement outside of the full Leaf stack.

Another option for removing the battery would be to slightly loosen all the bolts holding the battery, then remove all but 4 bolts. Lower the car down so the battery is sitting on a dolley with wheels, then remove the last bolts, jack the car up, slide the battery out and lower car. See my HalfPint ...

I had (and still have) an electrical fault that randomly kills my ignition feed for lights, windows, wipers, etc. I thought it was a loose connection somewhere, understandable given the state of the wiring, but it turned out that the body computer was getting ...

Major milestone achieved, it drives!!! I took a very short trip to Aldi (next door) after giving it a quick wash. I need to sort out 3 issues before it can be properly driven on the road. First, I need to implement a CAN bridge for both Leaf batteries ...

Do you actually need 70cm, how tall is your battery? I was able to support my van on 4 large axle stands, place the battery on a trolley made from an old door and casters. The casters are tall enough that I can get a floor jack underneath each end of the battery box and the door is thin enough that ...

A long overdue update on the van. I've had the battery box welded and painted.

Life has gotten in the way of working on the project but the battery box is coming together. It should be ready to go to the powder coaters on Friday.

It's currently being welded with some more strengthening to be added along the bottom and in the middle.

If you use the full Leaf battery then the ZV can get battery voltage, current and power from the Leaf BMS.

Both batteries will be connected to one contactor box although each battery will retain it's own service disconnect plug. After the initial connection the parallel connection will mean they are always at the same voltage. Today I checked both batteries and they are within 4 volts of each other ...
