Neat. Whats the output from these two commands: curl --version echo "$BASH_VERSION" I am using curl 7.68.0 (x86_64-pc-linux-gnu) and bash 5.0.17(1)-release. Why don't you modify the wiki to leave a hint or try to change the script so that it works on both versions? Might help the next per...

I am stuck at this step... I am not sure if it is something I am doing wrong? This is the verbose output of curl when I try to upload index.js. Screenshot - verbose curl output index_js.png I am not an expert, but it appears like it worked correctly? However, when I then go to 192.168.4.1/list, I st...

Edit: Right, I got the inverter out and back in, in case this helps someone in the future: "I updated ESP firmware from dc8b939.. to b61ccb1.. which has fewer print statements" I believe I have had this issue appear recently as I finally got around to implementing the Tesla PCS controller...

I tried to update the inverter controller firmware using the web portal, and it appears I temporarily bricked my controller by not updating the ESP-32 firmware first:/ upon refreshing the web portal after uploading the new firmware, the parameters section is empty and the activity light on the contr...

The logs provided by Solition1DC and P.S.Mangelsdorf contain no PCS messages so you have a hardware / wiring problem. Is there any indicator in the wifi portal that will confidently confirm the PCS is powered up if the HVDC isn't connected? The only value I see changing on mine during first powerup...

Given past experiences with Tesla chargers I would not try using the PCS with anything under 200v (250v to be safe) but I could be wrong. Thank you for the advice, I think I will just assemble a test pack at 250V. I am not in a position to collect CAN logs (yet) but I can make diagrams. V3 PCS cont...

Ken, Did you ever finish this project? Did you finalize the development of your crimp type edge connection PCB for the interface between the Telsa Flex PCB Model 3 module to the 3rd Party BMS? I somehow missed the notification on this. The system isn't fully assembled yet (embarrassed to say, but l...

I was going to add this directly to the Wiki but having never edited the wiki here before I don't know the ettiquete, and upon second thought I decided to share here first so that my work can be checked. I put together the attached diagram in preparation for bench testing my PCS before installation ...

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 i...

Step 2 : ??? Oh that's easy : Find QCA700x datasheet without having to sign NDA Write/port complete 7 layer network stack Implement CCS protocol (includes making decisions on stuff that's ambiguous). Repeatedly stab a voodoo doll you made of the IT dweeb who thought that as it's a "power"...

Stumbled on this browsing ebay- https://www.ebay.co.uk/itm/BMW-i3-Rapid-Charge-Interface-Module-Control-Unit-6135-9380352-Warranty/313113013065?hash=item48e6fd6b49:g:5j8AAOSwjE1e4kRT]BMW i3 charge port controller , part number 6135-9380352 Looking at the Munro i3 report, starting page 2093, it look...

Attaching photos of the X420 connector I have for info, last three pins not used on this one either. Just got hold of service manual and wiring diagrams, send a PM 22.gif 23.gif I just went though the wire labels and the connector datasheet again, turns out I was wrong. Tesla is using the manufactu...

That's interesting. So pins 10 and 11 are cp can that is not used by the pcs anyway. Sounds like they deleted them from the loom. Pin 12 is a ground that actually needs to be connected to the case of the pcs so I would also suspect they deleted that in favor of just using the case ground. My pin nu...

Update : 20/04/21 : attached pinout and connector data document Can you double check the X420 pinout in your PDF? I only ask because I am re-using the harness from my pack, and in the harness connector to X420, there are no wires in the sockets for pins 10,11, or 12, at least according to the pin n...

Yes, came as part of the pack:

Very interesting. That looks considerably easier to deal with than the busbars mine came connected to. What year/region/model was your donor, if you know?

Did your connector come from the factory with red and black cables?

I disassembled my pack myself, so hopefully I can help here. This is the HVDC connector into the PCS. 16214466548277475829813774427512.jpg 16214467035994290852159284330301.jpg 16214467595561513012667050070407.jpg I think it is either made to spec for Tesla or it is a Tesla made part, none of the num...

I just placed an order for your PCS controller, extemely excited to get this going... A charger suitable for my model 3 modules is the last missing component before I can start testing.

Good idea about fabricating a thin plate and threading in a stud. I'm going to try and replicate the technique.

We actually just cut off the ends of the busbars with a cut-off wheel on a dremel tool, then re-used existing holes to attach our own connecting bus bars made from Eriflex flat bus bar material. I don't remember seeing any copper colored material at the cut ends. Very possible they used different m...

I am going with an off the shelf BMS... I would prefer to solder additional cables to the original board to use any BMS Not a topic for this thread but be extremely careful with "off the shelf" BMS systems and Tesla batteries. We have seen several examples of destroyed modules and very po...

I thought I would share this here, as an aside replying to the prior discussions about using edge connectors with the flex pcb cables on these modules. This is a photo of a partial solution, tested on a spare flex PCB from eBay. Tesla model 3 BMS flex pcb with crimp contact.jpg As excited as I am fo...

Very cool. I am using a model 3 pack in my conversion... my box design is completely different, I will have to do a writeup when I am done. I am in a cold climate, so I decided to use a high strength fire retardant structural foam to provide most of the structural connection and double as insulation...

The "spoof enova commands" plan is currently stuck until I find a newer version of the enova interface software to interpret a fault the inverter is spitting out, in the meantime I decided to disassemble the power stage and learn what components were used in the construction. At the core a...

Since it sounds like the V2 or V3 openinverter system is an option, am I right in thinking the next step is to determine if the current sensors and gate drivers already present in the inverter are compatible with the brain board?
