Ok then I suggest to make a graph with the web GUI of the amp limit setting (of cp line) maybe it jumbos around a bit..m.art.y wrote: ↑Fri Jul 29, 2022 12:35 pmTesla gen2 and gen3 chargers are essentially the same control wise just that gen3 has more power. So Arber just to confirm your Tesla gen2 charger is not doing this? I wasn't sure if this is normal or not just wanted to ask. Otherwise if that behaviour is not normal your guess about CAN intervals makes sense. My CAN lines has 60 Ohm resistance so should be all good there. Besides I only noticed this when I started using EVSE, before I was just applying AC manually and the charger didn't seem to do this.arber333 wrote: ↑Fri Jul 29, 2022 12:10 pm Could be that your CAN telegram repeat time is too long and charger sees lack of signal and throttles back. When is sees the signal again it quickly revs back up.
Or could be that rev3 needs some fast heartbeat telegram similar to outlander at 30ms interval?
Try to shorten that time between telegrams maybe it will help...

Re: Tesla Charger Support Thread
Hi, this repo has SAM3X version of control board for Tesla gen3 charger but there is no arduino software for it. While gen2 arduino code works with gen3 charger it is limited to 16A per phase. I tried increasing what I thought were the limits in the code but it had no effect or stopped working altogether. Would you by any chance have a gen3 arduino code somewhere or would hint what need changing to be able to use full power from gen3 charger?

Re: Tesla Charger Support Thread
All modules are powering up, based on LEDs on each module.
Board LEDs are as shown, with upper LED (of two stacked amber LEDs) flashing (might appear solid in photo - it's not).
I can read battery voltage at DC connections on charger, but it is not outputting DC voltage (in other words, contactors are open but battery is not being charged).
Any suggestions?

Please post the output of http://192.168.4.1/cmd?cmd=json
Very likely the CAN termination solder jumper below the wifi module isn't closed

Solder looks good. I heated it up and added solder to both sides again, just in case.

Re: Tesla Charger Support Thread
So state=EVSEActivate which means it should be charging but at the same time there is absolutely no comms from the chargers. The mapping bug didn't exist in v1.07.R so it must be something with the physical bus. Maybe bus shorted when soldering in the connector?timbradley wrote: ↑Mon Aug 08, 2022 2:53 am Solder looks good.

Re: Tesla Charger Support Thread
Thanks Johu!
I had the soldering done by a local PCB manufacturer. He's pretty darn talented. The only solder I did myself was the termination jumper.
I can inspect the board under magnification, any other suggestions to search out the issue?

Re: Tesla Charger Support Thread
greetings, to see who can guide me since I am starting a project with my bmw x5. to use a Tesla gen2 charger I bought the card but when comparing it with others I see that it is missing a piece that goes in point 1C4 and I would like to know if it is necessary for me to have this and if it is necessary what should I do because I don't know what it is. Thank you

Assuming you're using a Gen2 charger, and a v5 board, you can actually view the schematic for yourself here :bmwx5projet wrote: ↑Tue Aug 09, 2022 3:48 pm greetings, to see who can guide me since I am starting a project with my bmw x5. to use a Tesla gen2 charger I bought the card but when comparing it with others I see that it is missing a piece that goes in point 1C4 and I would like to know if it is necessary for me to have this and if it is necessary what should I do because I don't know what it is.

Looks like this is the FTDI chip (USB to serial). This is, I believe, used to configure the charger settings. I have one, but have not set it up yet.
I see the v5 board also has a separate serial header (conn9). So, I guess you could make do without IC4 if you had as separate FTDI board/adapter and connected it to conn9. FTDI boards are cheap and easy to get.

Re: Tesla Charger Support Thread
Ok i have an issue.
Not with the charger... it runs just fine.
Not with the board... it also does its job.
Maybe the formware? Or my settings?
I replaced 3x of my 3kW eltek chargers which were charging ar 9kW but would not abide by EVSE Cp signal.
I put in Tesla gen2 charger and used open source firmware with serial setup.
I did setup in evse mode with 20A phase limit.
Charger only goes up to 8.5kW! Why would that be? And i tested at various voltages as to eliminate constant power tapering. Also i tested on various L2 EVSE in Slovenia. See the photos.
Did anyone come across similar behaviour?

Re: Tesla Charger Support Thread
Hi, are you using the arduino code with SAM3X version of the board? In that case you can plug in USB cable and open serial terminal in arduino. It reports very clearly what each charger is doing and what amperage it is charging at. Can you take a look if each charger is charging at 16A AC? It also shows there what cable limit it is receiving from EVSE. Or can you take a screenshot?

Re: Tesla Charger Support Thread
Didn't know this version of firmware existed where did you find it? I'm using Tom's firmware on SAM3X board. So can you access serial debug info at all? Mine works and AC current ramps up to 16A max but then it drops to ~2A and ramps up again, does this every 10 seconds or so..

That is exactly what i am seeing. Goes up to 8.5kW and dances about 500W. Could that mean each of the modules sees something faulty in its CAN command and starts to reduce but is then overcome by correct telegram? Or is it that Cp sensing is not very precise. I count some 2m of unshielded wire from socket to charger.
Yeah... about debug... the way i installed the charger i have to gat it down and take the lid off. My plan is to put a small cable through the lid and use it to connect to FTDI to have serial connection. Then i will be able to see debug...any day now.

Re: Tesla Charger Support Thread
Post a canbus log of it and I will take a look at it. From turning charger on couple of those cycles and turning off.

I wasnt able to connect to CAN even with the alternative firmware.EV_Builder wrote: ↑Wed Aug 10, 2022 8:45 pm Post a canbus log of it and I will take a look at it. From turning charger on couple of those cycles and turning off.
I will setup a twisted pair as well then...

Re: Tesla Charger Support Thread
Hello, thank you very much for responding to my concern, the card is a V5aB3, would it be mandatory to put the chip in it for it to work and if so, how do I program it?chrskly wrote: ↑Wed Aug 10, 2022 12:01 pm Assuming you're using a Gen2 charger, and a v5 board, you can actually view the schematic for yourself here :
Looks like this is the FTDI chip (USB to serial). This is, I believe, used to configure the charger settings. I have one, but have not set it up yet.
I see the v5 board also has a separate serial header (conn9). So, I guess you could make do without IC4 if you had as separate FTDI board/adapter and connected it to conn9. FTDI boards are cheap and easy to get.

Re: Tesla Charger Support Thread
Sorry, I'm causing issues here by trying to chip in to answer questions, but only getting it about half rightbmwx5projet wrote: ↑Thu Aug 11, 2022 1:40 am Hello, thank you very much for responding to my concern, the card is a V5aB3, would it be mandatory to put the chip in it for it to work and if so, how do I program it?
You can use the board, as-is, without having to add anything. The board has a WiFi interface and can be configured/managed completely from there (of course!).
See previous comment from Damien on this ...
