Everything wired up according to the pinout supplied at first post.

Can't get any pcs values from Web interface, connecting and logging in went great

I have selected eu version,

Is there any more changes to get things working?

Got 5v at pin one and pcs is mounted in penthouse,
Also got 13v at pin6(pcs-enable) with or without communication cable connected.


Attached a picture of my pcs:

Is the 12V battery connected?

Yes 12v battery is connected to m8 studs, it is 13v at battery poles for the moment. Should i try without the battery connected?

My pcs controller came presoldered so this is my first test,
3v3 led is on and the other one is flashing.
I have also solder for external can but that's not yet connected.


Edit number 2: After some experimenting i got the dcdc charging to work, works perfekt.

Now got ahead trying with controlling via canbus, Read the manual to gen 2 controller, but it seems that can message is shifted a bit.

0x102 b0: 0x0 b1: 0x78 b2: 0x1 b3: 0xA (idcspnt 10A) b4: b5: 0x1(enable) b6: 0x46(soc 70) b7: 0x0

Bit 1 and 2 results in udclim @ 376vdc

When enable Di1/Input 1 and can enable i got my smart charge adapter to apply 400vac 3phase.
Proximity: on enable: on canenable: on

The only thing i get really confused about is the parameter: uac, it is around 6600V

Think i have read everything on wiki but i don´t get it to work, anyone else that got it to work, besides Damien? =)

Another thing i read i the manual, can it be so simple that my unit not are registered correctly and my 5 minutes of charge is finish? i did buy a "full" kit

Hello ! I can't find design files for V2 tesla model 3 PCS - can you help me with this ? Also I can't find this design files on Patreon..

Just published on Patreon. Apologies I had forgotten.

Hello

Did not get my EU pcs to work correctly yet...

Is there anybody that got things going as planned?
The problem may be that the multiplexing canbus is wrong.
I still got around 6000vac when evse enable 3phase.

Otherwise the most of parameters seems to be correct

I did buy an extra charger from a Mitsubishi in the mean time to get things going

Best regards Fredrik

Just wondering if there's much ongoing work on this project? Was thinking of using the Model 3 PCS but wanted to know if it's stable or likely to be in the near future.

I have a US M3 pcs running in the grey goose as a daily driver past 6 months. The controller was also tested on a EU pcs from a 2019 vehicle before release. I know some folks have had issues recently and I will be investigating as much as possible soon.

Hello ! I can't get firmware for Model 3 charger from https://openinverter.org/shop/index.php ... duct_id=67

Can you help me ?

Do not think it has been released yet because it has not been fully tested, if someone knows there should be JOHU

Have you designed your own board or need to reflash

I bought board on JLCPCB

Tell me who to contact about the release date of the working firmware for Tesla Model 3 PCS ?

This question was asked above and I did not see an answer: Does the PCS need pre-charge or can it be connected direct to the HV battery?

I am only the programmer, not the developer of the PCS firmware. I have coded what others have reverse engineered and I have no direct facilities for testing or more reverse engineering.
Anyway, I uploaded the firmware as it stands to the link posted above. It may or may not work. Actually it is known not to work on EU models.

Im trying to design my system, and would like to use the PCS controller, with an Orion BMS.

However both have pilot and proximity signals, so I am confused.

Can they coexist , if so what would be the recommended way to do that?

Can someone please clarify the polarity on the J1772, HVDC and 12V connections on the PCS?
I'm using a US Model 3 PCS.
In exchange here's the info on the PCS controller connectors and terminals. Connectors already come with seals.
Thanks in advance.

I also have this question. Can anyone provide the HV pinout for the PCS?

Much appreciated.

In an effort to assist those using the PCS I have now released fully functional and commented firmware for the original SAM3 Arduino Due based PCS controller :
https://github.com/damienmaguire/Tesla- ... r/Software

This was heavily tested in my E46 touring before moved to the STM32 version.

An update from my side, too. I worked with fredd a bit and discovered one byte that needs to be 5d on the US version and 2d on the EU version was always sent as 5d. Maybe that is why his EU version didn't fire up the charger.

Yes think we did come very far with the STM32 software

After some weeks of programming and optimizing the PCS controller shows all values correct.

Even the dcdc converter works at full power. maximum draw so far is: 14v@200A

The only problem left is that the charger wont start, think we need you Damien to have a quick look at canbus logs to see what the problem can be.

The last question was eu/us version 2d/5d but that did not fix the problem.

I think that the problem can be some "emulated" messages to pcs unit.

Attach 3 log files if anyone have some spare time to check

With the current software, if the PCS sees 12V first, is precharge of the HV necessary?

I'm having a hard time with getting precharging set up when I want the inverter off, i.e. for charging. I've got a plan but its a bit more complex than I would like and parts are not playing nicely.

Alright so I've got my PCS wired up and no luck yet. Question: Do I need to change the PIN setting, and if so where do I find what my PCS needs?

Do you use software from Johu or Damien?

Have you followed the pinout in pdf at page one of this thread? I did my work on an original batterypack so i got the original cable with markings on each line.

Seems like the US and EU version got the same pinout.

Yes I have the correct wiring.

I'm not referring to the pinout. In the web interface, under the Version heading, there is a setting labeled PIN with a string of numbers. Does that setting need to be changed for each PCS?
