Good morning all,

I have a gen3 Leaf PDM here, and cannot find confirmation online about HV connections,

I have attached an Image of said PDM, The Black circle represents DC in & Dc out for charging, Left connection being + and the right connection being -, The blue circle is for aux DC out - for ...

Also probably good to note. We have tested gp2 completely disconnected by continuity to gnd, and found the same results as testing connected to the relay.

Thankyou for the reply,

Yes the Vcu stays in charge mode when cable is disconnected from the PDM. Also stays stuck in charge mode without gp2 configured.
However, when gp2 is configured and supplying Bms with wake signal (via a relay) when the charge cable is removed, and then the gp2 removed from ...

hi guys,

also having an issue with GP2, I am using it to switch a coil on a relay to control our pump during charging and also our bms wake signal, it doesn't enable reliably every time and when it does it doesn't then cut off when the charge cable is then removed keeping the VCU in charge mode ...

Hi guys, Has anyone tested CHAdeMO with 2.00??

We took our car to the local fast charger this morning to test, following testing driving and AC which were both successful

However we failed to get the car to charge on CHAdeMO..
I have attached our settings for reference.

It seems as though the VCU ...

Further from my post yesterday I have also noticed after going in to run or charge mode, UDC remains at pack voltage. see attachment

Afternoon all!

Trying to work out the gen 3 pdm

I have attached a image woth some annotations of what I have worked out connection wise. Please feel free to correct me if they are incorrect.

I cannot find anywhere the polarity of the AC in connections.

Anyone able to help?

Tia!

hi guys,

Following the (very exciting) release of V2.00 firmware - Thankyou Damien and anyone else involved.

We have successfully charged using AC however we failed to successfully charge using CHAdeMO..

Should '42 - interface' not be an option as apposed to the bullet points currently shown ...

SUCSESS!!!

We have CHAdeMO Charging! 8-)

So we bypassed the logic board within the PDM (Gen 2) tried it at our local charging station and it charged!

So now on to the next challenge, As it is, the way the CHAdeMO is integrated means that only AC OR CHAdeMO charging will work at one time. It ...

In our setup (gen 2) we are not relying on the pdm for any communication due to the zombieverter taking charge of this, so could we bypass that logicboard and wire direct to the contactor relay coils?

So following on from catphish Posts, we have had a chance to test the CHAdeMO.

I Can confirm that CAN now works! :D I have attached some supporting images.

However no current flow. We have established that the CHAdeMO Contactors are not closing. Within the pdm - (Picture attached from Johannes ...

Yes, so on the pdm p8 is fast charge relay (+) and p24 is fast charge relay (-) We have connected p2 and p10 from the fast charge port, but as stated the contactor does not seem to be shutting. During the test we conducted no voltage was present at P5&6.

Regarding CHAdeMO with the leaf pdm, Using Damien's video guide we wired up the zombie and the pdm accordingly, however we have come across some issues, The zombie side seems to be working, as when 12v is applied at p2 of the CHAdeMO plug, the zombie precharges and closes our systems contactors, and ...

Brilliant, Thankyou so much for these, extremely helpful!

I have heard people have successfully had CHAdeMO working with the zombie, however what is not clear is weather the zombie is controlling the start/stop signals etc or if people are using a series of relays to implement this and just using ...

Following my previous reply here is some supporting info..

attached are my pinouts for the pdm (Gen2) and also the pinout i'm using for my fast charge plug.
As you can see my pdm plug is missing pins which are in the schematics posted. but does have fast charge related pins.
Do you have the ...

Thanks for your replies,

Paulheystee, that schematic, is it for a gen1 leaf? It doesn't seem to match up with the pdm wiring I Have for my gen 2.

Hi guys.

getting to the stage to implement the Chademo charging on my project.
Software wise the latest version on GitHub has Chademo 'implemented' using can 3
However after an afternoon of scouring the forum I cannot seem to find any discussion about the physical wiring and process of Chademo ...

Any progress on debugging the latest firmware?

Hi guys following my wifi nightmare, i have (In short bursts) been able to reconnect and confirm i am on the latest firmware,
i have a couple of questions regarding this firmware..

After loading the firmware it shows i am still on version 1.00a but i have defiantly loaded 1.01 and also the can ...

If this is reference to my previous post, we are only using firmware from github. Any advice as to why the wifi was lost?

Tia

sorry should have included that info, still have power led and activity led flashing on the VCU board itself so not the same as in the wiki videos

SOC is for informational purposes only. Please see the video links in the wiki page. Are you running the latest release firmware?


Have checked over the videos, decided to reflash the VCU with another version,
It did go to 100% and 'update complete' on the interface, so I power cycled it and now ...

SOC is calculated using data from "BattCap" at the isa shunt. The interaction of the charge parameters is explained in the instructional videos to the best of my recollection. However I suspect your battery is full. Charge is terminated when 1)Idc drops below IDCspnt AND 2)UDC exceeds Voltspnt. So ...

Good afternoon all!

Having an issue with my ZombieVerter / Leaf Gen2 Setup..

I have the setup in the car - (complete gen2 motor, inverter & PDM)
I am using LG Chem batteries, 300v (4x 5 batteries in series strings)
and obviously the ZombieVerter!

I am currently trying to get the setup to charge ...

Hi there,

Sorry for that, I was thinking of which thread to put it in but given the VCU showed no errors and presumed it was leaf issue, I thought it would be best here!

I have now tried with 230Vdc, With no change,
Also tried a hall effect throttle to see if it made any difference, again no ...
