Looking inside the Leaf drive unit (Inverter & PDM)

[mcgousha]

Not sure if this will be of interest to anyone here, but as this community has been such a great source of information to me, I wanted to give something back.

I have a bunch of videos and pictures that I took as I disassembled the Leaf drive unit I am using in an EV conversion.

I figured i would share these here in case they are of use to anyone.

The drive unit is a 2nd generation one from 2014 with the components in a single stack and the EM57 motor.

The videos of the inverter are here:

And the PDM/Charger are here:

I'll upload the photos in a follow up post. I hope somone out there finds this stuff as fascinating as I have.

That looks like a good candidate for the "Sticky" topic I'm building...

 

[mcgousha]

Let me know if there is anything i can do to help your topic (if there are any specific pictures or videos you need i can try to take them.)

 

[LeftieBiker]

It will just consist of (labeled) links to helpful topics. Maybe others will chime in on what videos would be especially helpful.

It took a while, but I finally got around to taking a look inside the Leaf Gen 2 gearbox.

Hope this is of interest to some of you.

At the 1:24 mark of this video:

I noticed the external plug that has the 12v/CAN/resolver wires. Is that easy to get a hold of? Does anybody have a link to a place I can order that?

Thanks for the deep dive, hey Hi my can you tell me what this Nissan leaf 292A2 3NF1A pushes on inside the 6.6kw PDM unit, I'm having trouble with mine i have to rap tap on the end of mine to make it a little longer to make the car work and not give me Error P31E0-13 HV system interlock Error EVC-300.

 

[xboxice]

it plugs in here but what does it pushes on inside.

There is an anvil in the lid that compresses the spring arm of a microswitch in the PDM.

Thanks my Leaf is ZE1 so a bit different I think here is the cover that presses against something inside PDM

 

[xboxice]

Here is the access cover that presses against something inside the ZE1 2018-19 PDM unit

 

[nlspace]

Is that the cover plug for the connection to the Drive Inverter below the PDM? i think there is a microswitch in the lower plenum of the PDM in that location.

Yeah it is

 

[xboxice]

Yeah it is

Can you take a picture of what that looks like

[nlspace]

The microswitch is mounted to the bottom cover
May have to trim the plastic off the tapered section of the plug so the dowel rod can compress the switch. Or extend the length of the dowel rod, weld plastic or epoxy. Lubricate the oring so the plug slides in easily. Examine and clean the flange surface, etc. Whatever it takes to extend the dowel to contact the switch.

You are installing the plug with the UP arrow pointing up?

 

[xboxice]

Yea
