This is interesting product. Did you get yours from some distributor or is it sample from Isabellenhütten?

Good, and pictures shows also udc and power values so CANbus should be fine to both inverter and shunt.

When you press throttle, pot and pot2 are getting higher, right? And how about potnom and torque, does those change value too?

Looking for wiring harness between inverter and car. That resolver cable part number is 8556A131.

Yes, connection to inverter is simple, still looking nice and water proof oem connector. Sometimes its possible to find connector with inverter, but I have few spare rear inverters already

Has anyone found oem wiring harness for rear inverter? Tried to find part number without success yet. Yes, there is 3D print option, just would be cool to find correct wiring harness part number to see if its possible to find it.. and most likely only cut inverter data connector from it

Strange, maybe noise on fault signal to OI board triggers it? According to datasheet:
"When the voltage on the DESAT terminal exceeds 7 volts, the output voltage (VOUT) to IGBT gate goes to Hi-Z state and the SSD/CLAMP output is slowly lowered. FAULT output goes low, notifying the microcontroller of ...

2) no, I have not found how to use desat


IGBT driver /FAULT = desat output is open collector type and output of all six driver is connected parallel to one signal and on IGBT module there is pull-up to 5v. Same applies to /UVLO signal.

Now looking at your pinmap these pins are not "5V", but ...

Not sure you have the same heater, but mine and some others heater did not work with messages zombie sends. My heater model code is exactly as Damiens, so there must be some mystical difference:

I have not checked the difference as I control ...

What OBC does this one have? Could it be same as here:

OpenInverter CAN tool has been absolutely great, beside normal usage I update Zombieverter firmware quite often and there has been no problems at all.

Using Innomaker USB2CAN adapter with Linux and kernel buildin drivers and no need to compile driver like with some adapters. One nice feature is to ...

I stripped out all of the UDS stuff for now, Leaving that for the CAN-Bridge...
It should have a pretty good basis for CCS charging; So if you happen to have your system wired up with the DC Bus connections, I'd be interested to see if you can play around with the code to get it to work.


Nice ...

Finally found matching NW12 water connectors, from BMW dealer.
17108417218 / 8417218 is straight for 17mm hose, this was only 2€ from BWM!
81318423188 / 8423188 is 90deg sadly only for about 9mm hose, 10€ from BMW

This may not be aggressive enough, probably PI-control would be preferable and not oscillate as much
..
Right now my reaction is to disable traction control entirely. I think it would indeed be a good idea to disable regen in that case.


I've been testing same with ZombieVerter, best result with ...

When using mostly with zombie I can't see all spot values, just for example I12 and current time values. What makes values to be shown?

Also I think I saw current CAN mappings in the beginning but now shows nothing. Tried to add one mapping which did not show up in UI, so I verified with OIC tool ...

Many thanks, this has been great solution to add wifi range! Will try with external antenna some day to get even better.

are you using Windows? I've some fresh boards coming and will do some step by step instructions for boards out of the box.

The bad size given might be a library version issue https://github.com/espressif/arduino-esp32/issues/6482


I only use Linux, esptool would be nice but I did not get it to ...

In first place I did try wrong branch, after getting correct one it gives me some errors about setValueSdo() function, commented errror lines to get lilygo-tcan compile somehow.

I have not used esptool.py before to flash whole thing, so I compiled using Arduino 2.3.3 and same board settings as ...

I don't know how to put this to not sound quite wild, but... I'm pretty sure the Kempower charger I mostly test my car at doesn't connect PP, either at all or at least not during the actual charging session.


All logs I have taken from many Kempower it does have normal PP value and no problem ...

Ordered some 3B0122291B and sadly those was larger NW16. One from amazon with bleeder seemed to be physically much larger on pictures. So hunt continues

Is anyone familiar with VAG parts, cooling connections are Normaquick NW12 which is not so easy to find. VAG might have part number to connector by itself or hose with connector for sure. Maybe I haven't found good spare part diagram to find part number.

Solved. CAN mapping showed none and always "Command or parameter not supported", no matter if I programmed bootloader and Clara with erase. Finally I did STM32CubeProgrammer full chip erase, which I believe is only erasing eeprom, programmer flash with openocd and voila.

Maybe I got into some ...

My home EVSE is Tesla Wallbox gen 2. Does anyone know is there something tricky with these, does it try to communicate using 5% CP?


This mystery is now solved also. Wallbox plug temperature sensor must haev failed about the same time as I moved to Foccci, I didn't notice Wallbox red LED ...

I might be too tired to find my mistake, cleared clara can map and run previously working oic script which no longer works for some reason. Tried with long time used 0.0.9 and also git version 0.1.0.

oic -n 22 can clear
CAN all mapping removed successfully.

EDIT: SUCCESS!! Edited hwIf_handleContactorRequest by commenting out contactor 2 delay:
ContactorOnTimer2=0;//-CONTACTOR_CYCLES_SEQUENTIAL;

And Kempower seems to ramp quite fast actually, so I would say these worked before there came contactor delay.

---older thinking---

Did not work before ...

Enable? Just to notice, current code does read button while AC charge, so without mod lock won't release.

Precharge 306v sounds about right for 79% SOC.

Before this log I did long CCS on another station, I highly doubt car contactor fault. I'll check from logs where you found this 324V, so I can see is same jump problem with all Kempower stations, as I just posted one log and tried yesterday two ...
