Sorry Tom, don't have a Charge Port Controller unit. I was trying to get the Zombie to go into charge mode and I was looking to see what should I select on
General Setup

3. Interface parameters
I have it set to CPC
Which is not working so it looks like ..I am doing it wrong..

I was trying to copy what Jamie had implemented in the video below. At 6 minutes

DIY BMW E91 EV Episode 6

If anyone has got this working I would appreciate some advice.
Thanks

There's a bug in the outlander charger implementation, I had to set interface to chademo for PP detect to work and go in to charge mode.

Thanks I will try that

This is an update on my project.
In Feb this year I had the first drive out of the workshop and up and down a small country road.
All was good only had to push it home once. 12v battery went low and car stopped.

In May i got a peugeot 208 50kW battery and it has taken me a few months to get it fitted into the car. 10 modules in the boot and six in the front with room for another two modules at a later stage.
The plan is to but a Kilovac contactor in the boot with a safety disconnect and fuse.

I had a bmw Sbox with welded contactors which is for scrap. So I have being playing with the possibility using this with Kilovac contactors.
I have bolted it together and mounted in a enclosure to see if it would fit together neatly. See photo.


The big questions I have for the forum members who understand the code is.....

1. Can I use the sbox shunt and use the Zombie outputs to drive the three contactors. ( negative and positive Kilovac and sbox precharge contactors)

If so what should I select in shunt drop menu.

2. Should I use the Zombie to drive all three contactors and select sbox in drop down menu.
3. I might have a problem with my pre charge LS output on my zombie.
Is there a way to test this or should I just get a new
NCV8402 mosfet fitted to my zombie.

I haven't put any thought into which BMS I should use.

Did you already have an ISA previously? If so, and you're changing at least the two main contactors, neatest solution sounds like moveing away from the S-Box/hybrid idea. I toyed with the same thing and if the S-Box isolation monitoring was fully working, it would be a benefit. But to me it sounds like the Kilovacs and ISA and ZV standard setup would be most straightforward.

Spent some time thinking about my setup and i have decided to scrap the sbox idea and go with the ev standard zombie Kilovac and Isa shunt setup. So i need to source a isa shunt

[manifold]

I am planning doing same for my outlander project. Scrapping s-box and going with Kilovac EV200HAANA and IVT-S-1K-U3-I-CAN2-12/24 shunt. Just sourcing all the bits to build a HVJB up now.

Progress is slow.

I have built the HV Junction box but I am still having issues with the pre charge circuit on my Zombie,


Does anyone know if its possible to command this LS output to activate a test to see if the precharge circuit is functioning
The shunt has been wired up since this photo was taken

Spent today working on my HV Junction box with the ISA shunt.
The three contactors are working as required and ucd and ucd2 are reading 246volts from ten batteries , will add the remaining six batteries from the front battery box in the next week or so.
I seem to have an issue with the INVvdc value. It's at 50% of the udc most of the time.
When I power up the Zombie it's at 100% the same value as udc ,,,,, but when I spin the motor the value drops back down to 50%.
When i changed the inverter can from can1 to can2 the correct valve showed up on INVdcu,,,, but again when I spin the motor it drops back down to 50%.
The actual voltage measured with a multimeter never changes 100% 246v.
I have purchased a second inverter but the issue is the same with both inverters.
All advice/ Suggestions are very welcome.
Below I are my parameters and spot values.
Thanks
Kevin

InvUDC values are not to be trusted. I don't think it matters. Zombie uses ISA shunt as the source of truth. My inverter spits out garbage for InvUDC

[Bigpie]

The invudc in the current release uses the wrong bytes.

Thanks Robertwa for your response. It's good to hear that other zombie/Gs450h users are having similar experiences.. Will try improved larger diameter standoffs (18mm) on the inverter but I will be surprised if it makes any difference
