Model 3 PCS Controller Support Thread

[muehlpower]

I have two EU and one US model PCS here. The US is from an early M3, I don't know about the EU parts. How do I recognize the compatible versions?

[P.S.Mangelsdorf]

I'm hoping to get back to wrestling with my PCS, (no DC-DC or charge working) some time this spring/early summer. It's a bit down the list though, behind axles, CHAdeMO, and roll cage.

Since the PCS software is closed source, how can we best help figure out what messages work?

The original Arduino based PCS software is open source : https://github.com/damienmaguire/Tesla- ... PCS_V6.ino

I am wanting to use a complete Model 3 battery in my EV conversion. I believe the PCS Controller board is only DCDC, charger, and charge port? Can the Tesla contactors and precharge be bypassed if using the penthouse? I'm thinking I could get the vehicle minimally functional, as in driving and charging, using the standard openinverter precharge and the PCS Controller board for DCDC and charger. I have not purchased a PCS Controller board yet and it looks like only a few people have gotten the charger to work. Is anyone using the complete penthouse?

Simply finding the correct can messages for that firmware version.

For this, is it necessary to get the CAN from a functioning car to allow the reverse engineering, or is it possible with only the PCS on the bench and probing its CAN?

I presume we need a functioning car so we need to start gathering up CAN logs?

Or is it possible with some educated/controlled fuzzing in Savvycan if ID's etc are narrowed down enough? I don't know if Tesla firmware changes typically mean drastic changes to CAN or minor tweaks. I have a 2019 EU PCS about ready to power up and test

Yes; that can be done but you need a proper CanBus description file (dbc) then.

Hello,

I just bought a board from Damien with the 35 way ampseal variant. Does anyone have a pinout for this board? Been looking everywhere but can only seem to find the Me-mx variant pinout.

Thanks

Until I get a wall charger set up, what would be the minimum requirement to be able to use the PCS with 240V single phase domestic supply to allow some testing and light charging of Tesla pack!? Is a fused connection to the AC charge input allowed? If US versions are 120VAC on two pins, will EU PCS work with similar?

Were you able to bench test the PCS before the attaching it to the batteries? I would like to test mine as well but I am struggling with the Arduino side of things. I have downloaded the .ino file from Damien but haven’t been able to run the code bc of the dependent libraries. I have been looking all over the internet for the needed librarie but the code will not run with the libraries I have downloaded. Is there a specific place that can holds them all or does the community have a better way of finding the libraries?


(EDIT: I solved the problem, there are multiple libraries that can be used by the Arduino code that Damien provides but they will continue to give you errors. You need the Metro library from collins80/metro.h, due_can from collins80/due_can, due_wire from collins80/due_wire, DueTimer from the arduino libraries, wire_eeprom from collins80, and AverageValue from Arduino )

[Gilbo]

I have been able to run the Arduino code that Damien provided and have been able to attach all but one wire to the Due which is the EVSE_ACT wire which is meant to go into pin 44. I do not know where I am meant to get the EVSE_ACT wire from but any advice would be really helpful. I also have managed to get Damiens board to read the voltage but there does not seem to be any more communication between Damien's board and the PCS. I attached what I see with the arduino Due and Damien's board plugged into the PCS, while the PCS is connected to wall voltage (not a charger) and the battery pack. If this is similar to what is expected I would really appreciate anyone letting me know if this is close.

I've not got this far yet but getting close to having to get back to the PCS, so not much help to your quries unfortunately. Keen to see how you get on, cheers

EVSE_ACT is not used on the dedicated controller, so I'm not sure where that should be. There's no activation pin persay on the J1772, and the code has provisions for pilot and prox so its not that. I'm lost as well.

Did anyone ever supply you with the pinout for the V3 PCS board?

Hello !
I use stm32 version v2 board with commercial firmaware (demo version for 5 minutes) made by JLCPCB (US version PCS) and have some error bits.
errbits0_2 8 (PCS_a032 unused I think)
errbits1_0 577 (can't explain this errors)

Can you explain this errors for me ?

Hello !
I concluded that my chargers have the wrong firmware with a modified DBC, could you read the firmware of your working charger? Or tell me in which direction I should move, I purchased 6 US chargers and none of them work

P.S.
I unpacked a rather old firmware from MODEL 3 and found the firmware of all modules there, including the PCS, but the firmware extension confuses me:
PCS_DCDC_charger_P3_A1_U1_CPU1_CRC.bhx
PCS_DCDC_charger_P3_A1_U1_CPU2_CRC.bhx
Tell me, is it just a firmware file or encrypted firmware

Cannot find a network to connect 192.168.4.1, tried using CAN wires nothing. Get red blinking lights, green light on wifi blinks quick only when turning on. Looked at videos did not find instructions on entering program screen. What is being overlooked?

New 35 pin board wired as follows:

The main board should have 2 leds. One on sold marked 3v3 and one blinking at 10hz marked "accty". The wifi module should also have two leds. One red on always indicating the module has power and the other flashes green at powerup indicating the module receives data from the stm32 on the main board. At this stage you need a laptop or other wifi enabled device and search for networks. You should find on with ssid "inverter" and password is "inverter123". Once connected, open a browser and navigate to 192.168.4.1 to bring up the web interface. Would be great if someone could please update the PCS wiki page as there is a lot of info that needs to be captured.

Boards are programmed and power tested prior to dispatch as with all the kits. As I have repeated in multiple threads I do not as yet have a workshop up and running to allow me to work on ev parts. Perhaps if those who have their PCS up and running could jump in to help those who do not then some progress could be made. Assuming this doesn't happen then the only thing I can suggest is to ask someone with a non working PCS and controller to send it to me so as we can get to the bottom of this. I have one US and one EU PCS successfully tested on both the original prototype controller and the new V2 stm32 version.

Hello !
Can I send you a controller made by jlcpcb (stm32 - all works fine) ? And one US PCS

[Jack Bauer]

Sure. Will be in touch in a week or two to arrange.

[Wise]

Sure. Will be in touch in a week or two to arrange.

Hello ! Can you tell me when can I send you a charger?

[nkiernan]

If its a help to have a couple of PCS and controller units for a comparison test I should be able to send a set too

[Jack Bauer]

Will advise soon. I need a bit of a basic workbench setup before I can do anything useful:)

[Ken_S]

I'm beginning the process of integrating my PCS under the hood of my vehicle... I am rewatching Damien's demo video, but in case the answer isn't in there, does anyone know how the shell of the PCS should be grounded? My current mounting solution connects it to chassis (12v) ground, I am wondering if this needs to be changed.

[Jack Bauer]

Can those with non working pcs who have offered please contact me via pm to arrange shipping to me? Hopefully we can then get to the bottom of these issues. Thanks.
