Been slowly repairing the car every now and then. When making a loading test with an electronic load, the NiMh battery turned out having 7 defective modules out of the total of 40. I managed to get some (9pcs) replacements and redid the test. I balanced all modules (over night) to the same voltage f...

Around a year ago I "finished" switching to the EQC modules and managed to shoehorn 40kWh of energy to the trunk of the RX8 (half an EQC pack, as it conveniently has two parallel 400V strings). Then I got the conversion registered. Today the car passed it's first normal MOT, so once again ...

Hi, Thank you both crasbe and johu. Both resolutions work. The reason why I ran into this problem was because I am lazy... I am running the Linux on a Windows environment inside a Virtual Box. When changing the PC, I did not want to go through all the trouble of installing a whole new Ubuntu on the ...

Hello, I am trying to get the development environment running on another computer. Followed the instruction and executed the following commands on the terminal: sudo apt-get install git gcc-arm-none-eabi Installation goes through with no errors. When trying to make I get the following error: arm-non...

I opted for those batteries in the first place as I had some modules readily available. I was able to package half of a Think City battery in to the trunk, so 11,5kWh. However, the maximum continuous power output from this small pack is only around 20kW. As I wanted to preserve the sporty performanc...

I stumbled upon an old 450h with around 375 000km on it. Got it for cheap as it has (according to the fault codes) a defective aux oil pump of transmission and a single cell block failure of the NiMh battery. The car is driveable, but goes into some safety shutdown every now and then. I was planning...

Potentially a stupid beginner mistake, but bare with me... I cloned the template project, followed the given instruction and finally tried to compile without making any changes yet, but I get the following error: LD stm32_yourname obj/canhardware.o:(.rodata._ZTV11CanHardware[_ZTV11CanHardware]+0x8):...

I haven't tried disconnecting the INV Pin 18, but I did disconnect PDM Pin 15 and everything works fine. You might be wondering why I disconnected PDM Pin 15, right? Originally everything was working as expected with both connected to switched 12V controlled by INV LS switch. Then with some SW devel...

I was able to get my Volt heater heating up with the instruction given here . Special thanks to Thyristor for posting the CAN log. My first test setup was somewhat hacky with temporary wiring so after the successful test, I pursued to make the final connections and wiring. Unfortunately I was not ab...

I've checked the schematic, the complete layout and the jumpers multiple times, and all seems to be in order on that front. I have not checked how the Zombie actually sets up the speed of the CAN3. I have just assumed that it is tested and correct... When I succeeded in the control with the PEAK CAN...

I have been playing around with the Zombie and trying to get the Volt/Ampera heater control working. The heater control code actually monitors the GP12V input pins status and the heater is only enable whenever this input is pulled high. There is also a spot value for this on the web interface with t...

This is good news and extremely interesting! My design already includes common mode chokes, and I saw significant improvements by adding an Ethernet transformer, but I guess the OEM did it better! If you have any more detailed information about this filter I'd be interested. Sorry for not being cle...

I have cloned the newer firmware, but when I tried to make it I get a couple of errors referring to missing include files. I was able to generate a .uf2 by commenting out the deep sleep functionality. Anyway, I have made quite a bit of my own changes to the older version, so am a bit reluctant to st...

First of all, thank you Catphish for the great piece of equipment. I've tested the balancing by sending the balance_threshold via CAN and noticed that some of the cell voltage measurement values started to fluctuate quite heavily. at first I was somewhat alarmed by the fact that the maximum cell vol...

That is a good approach. Using one of the Zombie's output pins to keep the relay conducting, you can skip the "fancy" delay relay and just use any old relay that you can find.
Also, you could make the delay time a configurable parameter on the web interface if you like.

I was not happy with the "standby" power consumption of the Zombie either and also figured the manual switch would be the simplest solution. It, however, leaves a bit too much room for the infamous human factor. This is why I opted to include a delay relay to the system. If I recall right,...

In my own experience the best results were achieved with a short twisted unshielded cable. In my own car I'm using the 5v version with an external transformer. It's still not perfect, but with checksum checking, the majority of the data is valid, and any bad frames are simply ignored. I've now test...

I asume I do not have any check sum checking going on. The basis of my code version originates from here: https://github.com/catphish/lg-daisychain I was wondering about the updates being a bit old... I did some digging and found this: https://github.com/catphish/ti-daisychain-bms At least this vers...

Thanks for the tips. I have to check that checksum verification. The OEM slave boards with the bq-chip have a particular LAN transformer so I took it from one of the unused OEM boards and fitted onto your board. It is quite interesting that on the contrary to your suggestion, the OEM wiring harness ...

Hi, I finally got to the point in my build that I was able to test your board in my RX8. I have 40kWh worth of modules from a Mercedes EQC 80kWh pack installed. The EQC battery has the same bq-series cell instrumentation ASICs. I made some slight addition/modifications to your code so that I have mi...

Yes.

According to this thread https://openinverter.org/forum/viewtopic.php?t=1756 , the problem might be a filled up flash. All the symptoms seem to point to this direction. Here is what I get with "http://192.168.1.26/list": [{"type":"file","name":"chart.min...

Hi, This .bin file is a blank file. I recall Damien giving me the link for it. If you flash this file then power down and repower the Zombieverter then use the latest recommended .bin file on the github page it might cure your problem. I have tried thid method myself and it has worked for me. This ...

Thank you. I will give it a try.

After quite a while of working on my battery assembly for the RX8 it became time to implement the associated modification to the Zombie this evening. I flashed in my bin file and noticed that the activity led is not blinking anymore. In previous occasions this has been due to some coding bug and the...
