I got a secondhand Zombie from someone who abandoned their build. It was fully populated, but the software version was really old so I had to manually (with UART) flash both the board and the wifi board.

There's another guy in Hout Bay who bought the EUR350 one and is currently building it.

I'm ...

Hey elShankos, good to see you are making progress! I'm in Cape Town as well, and moving at the same pace. I've managed to get a Zombieverter properly configured on the bench, so if you need and help with wiring things up do let me know - happy to meet up and debug if needed.

Hello.

I bought 3 x Volvo/Eltek 3kw water cooled chargers from Zapatero when he parted out his Subaru AWD build. They have been sitting in my garage for the last 2 years, and I've realised that an Outlander unit would be more appropriate for my build.

I paid EUR299 for each of them, I'd be happy ...

Howdy! Interesting project. I have thought about similar configurations in a fair amount of depth over the last few years. Some thoughts, in no particular order -

1. The cleanest transfer case solution I have seen is to use the Land Rover LT230 to drive front and rear axles. Bulletproof transfer ...

Hi tensa,

I had quite a lot of trouble as well a few months ago. In the end, what worked was to actually just bite the bullet and update via UART.

I posted my feedback here if you need a bit of guidance. If I were to do it again I would just go straight to UART reflash.

Well, if you go electric AWD, you’ll need to figure out how to control both motors. Maybe one pedal signal split to two controllers? The alternative is one controller that is capable of controlling two motors. I’m not sure if anything supports that.

The rest of the low voltage, high voltage and ...

As far as I am aware the leaf BMS is tightly integrated to the overall operation of the vehicle. I think the only way you would be able to pull this off would be to purchase leaf replacement modules from a place like Alibaba and swapping out the old modules with the new ones, retaining the original ...

Hi Marvin,

I had quite a lot of trouble with updating past 2.15 on my quite old Zombieverter. The behaviour was as you described - no spot values or parameters. With 2.17 the issue was intermittent, and with 2.20 I pretty much never had any success.

I tried many different ways to solve the ...

Well, tom91, I just managed to get this working this afternoon while avoiding my day job. There were several issues which I will mention here as a possible help to others.

Mainly, this was an issue of user error, with a bit of undocumented 'earlier owner modification' sprinkled over.

To get my ...

I have managed to successfully connect the ESP32 to the ZombieVerter. In the end, I changed nothing from my last post. For clarity, here is the configuration that works for ZombieVerter V2.20. A lot of this is documented in many places, but I'm repeating it here anyway.

1. Connect the ESP32 to CAN1 ...

Although I no longer need to get the ESP32 communicating with the ZombieVerter because my Olimex is back up and running, I feel honour bound to try answer the original question because I couldn't find an answer when I was looking, and others will probably land on this forum post when they want to ...

Alright, mission accomplished!

Flashed the Zombie with an ST-Link V2, flashed the Olimex with a UART cable, all working now.

Thanks again for your guidance johu. The most surprising thing about all of this for me was that the Zombie can fail in a 'soft' way, resulting in a somewhat functional ...

I bit more info. I managed to totally lose connectivity to the Olimex and had to reflash it via UART.

The guide from the GitHub repo were good -

If you are looking for a pinout, the wiki has a good diagram -

I'm in awe that you can figure that out from my feedback. Make sense though. Ok, I will go buy an ST-Link v2, download the 2.20a hex file and load it. Thanks johu.

Turns out I was wrong on the successful comms with the Zombie. I was looking in the files section to see if I should delete some old stm32_vcu.bin files, and I found a json file called 2c389.json. The contents were suspiciously familiar:


"43014149","isparam":false}
}
"serial": {"unit":"","value ...

It locks up immediately after the call http://192.168.4.1/fwupdate?step=1&file ... _vcu-2.bin

The one immediately before, http://192.168.4.1/fwupdate?step=0&file ... _vcu-2.bin, gives me a 200. But the one that locks up does not give me a response.

Ok, I appear to be getting somewhere. I shortened all my CAN network stubs to less than 30cm. I spaced all my stubs along the main CAN line. Terminated on both ends.

Now, when I select NodeID 3 in the interface:

1. The red banner on the top disappears
2. In Chrome Developer Tools > Network I am ...

So I got out my multimeter to test out assumption (1) above. Turns out that:

1. I get 120 ohm across my IVT shunt CAN lines - it has a resistor in it according to the specs, so this is expected.
2. I get 0 ohm across the Zombie CAN EXT (A above) lines
3. I get 0 ohm across Zombie CAN EXT2 (B above ...

Well, I'm not having any joy. It's probably user error on my part, which I'm sure is exasperating for the old hands on here because once you know, it's obvious :)

When you say CAN1, do you mean A or B in the picture below? I know I have seen posts on here that mention that the references change ...

Hi johu! Good info, thank you kindly.

Hello,

Starting a new thread because my earlier questions were around the Olimex interface, which I have given up on.

I am posting to find out if there are any software configurations required to get the ESP32 web interface board communicating with the Zombieverter.

After my Zombieverter Olimex ...

1. Cheap
2. Both a charger and a DCDC in a compact package
3. Supported by the Zombieverter

Yes, I followed that diagram. Definitely no CAN comms from inverter.

It is possible that the pins are broken in the socket. I'll open it up, strip the connector and connect to the wires directly.

Hi tom!

Ok, so absence of data on those two does not signify absence of life in my inverter. Thanks for clearing that up.

tmphs = 0 and tmpm = 0 in run mode.

But, the inverter is not connected to the motor, and there is no water cooling connected, so perhaps that's not unexpected. I will ...

Hello,

I have been making use of the wiki and forum posts to wire up my Outlander Rear inverter to the zombieverter. I have made good progress with precharge and the throttle, but I am unable to get my InvUDC to go above 0V, or to get my InvStat to go On.

I would like to confirm that I have met ...
