I've been looking arround the interwebs and the forum for someone who had the same problem as me but in vain.

I'm building a car with the model 3 from and rear subframes, and i'd like to use the power steering rack.

I've tried to connect just the 12v to it but no success, it doesn't go in failsafe ...

I can test a new software version, to confirm that all is correct.

Hello,
I did the oven test, here is the setup, an old Stator from a LDU sport, extended wires for the temps sensors and a thermo couple hoked up to my multi meter to have the actual temperature and an other multi meter to measure the resistance of the two stator thermistors.
The thermo couple was ...

I'm sure i have some laying arround here, how many would you need ?

I do not know the details about the why it fails, but the mappings are at the end of the flash memory in Foccci. So to clean up everything, a "mass erase" of the STM32 on the Foccci board should help. How to do this? Using an STlink programmer, which is connected to the Foccci board via the 3-pin ...

Argh, yes something goes sideways when playing with mappings for a while. Need to implement the clear mapping command over SDO. Now you can only resolve it with an ST Link by deleting the last flash page (loosing parameters and mappings)


Do i need to reflash the wifi board or the Focci itself ...

I am experiencing some strange behavior with my focci 5.1 and wifi interface, after playing around with the can mapping and having every message configured properly but one, I can't add messages anymore.

So i got everything powered up, 12v permanent to focci and bms, wakeup of focci when i plug my ...

Got some 5.1 boards but i can't seem to find any information about pinout that are user freindly.
Also on the contactors control on version 4.5b that i integrated in an other project, they were High side switched, is that still the case ?
I want to update this schematics :

I finally got arround to making my CCS2 and type 2 work with orion BMS.

I just got one last issue with locking the plug in the socket when charging in AC, it simply doesn't lock at all. for now the BMS sends OBCState to 2 as soon as a plug is plugged.

What am i missing ?

Just got a new thing while remaking my can man

i haven't done the comments to remove the json issue, could this be linked ?

Edit : I've commented the lines, reuploaded the code to the ESP the wired way, but still no luck. same behaviour, i can't add can messages to the can map. I'm ...

Digging up a relatively old thread but, i'm in the same situation. How did you send 0xFF from foccci to your orion bms ?
i wasn't able to understand what's the special can sauce that enables the orion bms to not have the cp and pp connected to it.

i have a foccci and orion bms 2 wired up and ...

I confirmed that this schematic works. Charged in CCS2 yesterday.

Do you see fly them around? Or any chance to get replacement and solder them?

Sadly i don't see them, i openend the box quite a few times. i'll get some replacements on the road asap.


Q13 looks like the pad has been completely ripped off. you might need to scrape a bit of the mask off the ...

I noticed that the wakeup functionality of my 4.5a board doesn't work, it gives 12V but i can't draw the 160mah that my setup uses.
I belive that the missing Q13 and Q11 could be the culprits. I wasn't able to find the schematics of V4.5a on the github

Could someone ...

With platormio i did an upload but then i couldn't connect to the wifi anymore.
I updated the firmware via the arduino ui, then with platformio i did a uploadfs.

here is what i get when i change the node ID or the can speed.

with arduino ui (1.8.19) i can't use the esp8266 upload ...

Hello,
I just installed the latest version on my esp 32 can lite module so now i have the button to change the CAN speed just under the node ID, amazing.

Problem is that it seems to not work, as in the can speed doesn't change when i change it on the button.

regardless of the can spee ...

Yes, AC and DC charging. AC monophase 6.6kW

Hi,
The DC link capacitor is rated at 430V on the SDU i was runing a 102S pack limited to 429V and it blew up.
I also know of a system runing 440V on an SDU without problems, so i guess parameters play a big role.

Yes, they are exactly the same casing, bolt holes and everything. As far as i know the powerstage is the same. Just swap your logicboard and make the busbars.
Yes your link to an FDU is what you would need.

Yes same inverters, the phase wires are about 40mm shorter on the Front drive unit, so you'll need to make some little busbars to be able to connect the phase wire to the motor.

for the wakeup,
The orion bms expect a 12v when the plug is inserted/ when the bms needs to send the charge commands.
The OBC sends a 12V when the AC is applied.

Updated taking your advice.
I've added a PDF version as well.

Hi,
Most likely one on the igbt is dead, that's why the inverter shuts off. The SDU inverter is really hard to repair, and usually it'smore economical to get a front drive unit and take the inverter.

Hello,

I'm planing the integration of the focci module in one of my conversions.
I wasn't able to find a wiring diagram so I made one, if those who have integrated it could correct me if need be, i'll make the updates so it can be usefull for others.
Focci board 4.5a as it is what I have.

Focci ...

I just got my boards ealier this week. I all new to the pico workflow, how am i supposed to use the firmware folder ? I've read that you can setup visual studio to compile the firmware, i that what i need to do ?

I'm not that handy with the fimware/code side of things if you couldn't tell.
