Nobody tried above 500V, I guess. Regarding unloaded tests: Different chargers behave differently. Alpitronic make a perfect regulation, no matter whether they are with no load. Others overshoot the voltage and shut down.

Well, this could be the trigger to integrate also the ISO schema besides the currenty used DIN schema. Seems possible, but some work to do. Is your charger rated for 800V?

The target voltage of 790V will also not work. The DIN schema, which Foccci/Clara uses, supports ususally 500V maximum voltage. This limit normally would be visible in the ChargeParameterDiscoveryResponse here: https://github.com/uhi22/clara-logs/blob/180cabf76ad4bb507d5f524c00889ba4d2cc3177/2024-05...

Do you have any chance to measure the CP with an oscilloscope? There could be not much wrong, the charger just needs one diode and two resistors to make the ABB happy. Or maybe the ABB is broken, and just providing a strange error message...

All the values were consistent with CCS1 No. In the log we see e.g. [931600] ResistanceProxPilot [ohm] 895, this is for sure not consistent (or at least the explanation is missing). And it is not consistent that later in the log the ResistanceProxPilot jumps to around 200 ohms. It would be really h...

Could also be normal. The PP resistor should be in the plug and nothing else is mandatory on the PP. Is it possible to take a multimeter and measure the PP resistance while everything is off and disconnected?

Okay, then my proposal is: At startup of the esp:
If numberOfBinFiles>1 then deleteAllBinFiles()
This keeps a single file forever, and cleans up multiple ones.

From my understanding there are two classes of parameters: one is stored in flash, the other is volatile. Maybe you try to store a volatile parameter. Or does the issue happen for all?

Just to be sure, "sharing the same PE" means, that the following signals are together: - Ground of Foccci - Ground of the 12V supply that feeds Foccci - PE of the CCS socket - minus of the multimeter if you measure the PP voltage on car side (around 4.5V if nothing is connected). - ground ...

Regarding the topic "ESP file system gets full due to multiple bin files", I understand that one fix is to delete the bin file after successful update. The above commit implements this fix in the javascript, means: in browser. Right? This helps in case of successful flashing, but for the u...

Yes, there seems to be confusion with the pins. There are three: 1. The PE, protective earth, chassis ground. This needs to be connected to the ground of Foccci. This is the reference point for your multimeter. The single 6mm pin in the center. 2. The CP. Control pilot. This needs to be connected to...

The dealer announced it here https://m.mobile.de/auto-inserat/tesla- ... 8c&type=ad
Quite expensive, 30k euro for such a broken car.

In a comment to the video ( we got a confirmation from mizettelzettel that pyPLC together with 350V physical voltage convinced a Tesla model 3 to close the contactors, and drawing 4kW over 30mins was working without error.

No, the coordinator setting cannot be changed by the car, and also pyPLC does not touch this. It is only changed by writing a PIB. At least I see no other way.
"Always" is the correct CCo setting for the Evse.

As @jrbe proposed, we could try to improve the docu using AI. This thread is intended to discuss the possibilities and the results.
Any Idea welcome.

To cover the typical mistakes "CP and PP mixed up or not wired" just added hints in the trouble-shooting chapter: https://github.com/uhi22/foccci#no-comm ... r-possible

Could the following concept work: - for the high-power stuff use a 22kW charger from a car. This takes 3 phase AC and provides HV DC. I think Damien reverse-engineered a MG charger which seems to be controllable via CAN easily. - into the type 2 direction, use an Arduino which measures the CP PWM an...

To simplify trouble shooting the CP and PP lines, added ResistanceProxPilot to the serial logging. If the charger is plugged in, we should see something like cpDuty [%] 5 ResistanceProxPilot [ohm] 1495 The CP PWM duty cycle should be between 4 and 6 percent (5% nominal), and the PP resistance betwee...

On my daily way, I see a Tesla M3 (or Y?) at a "dealer". It has quite some crash impact on the back, but I think a lot of parts are still in a good shape (battery, drive unit). It is sitting there since weeks. Personally I do not have plans, but if anybody is interested, maybe it is possib...

Also wondering if this is a change I may have to make. I found these bits of doc in the CCS1 protocol documentation and it seems that in a certain setup, 4.7k is optional? There are two different use cases: CCS type 1 and CCS type 2. The upper picture, with Rs3 and Rs4 and button in the connector, ...

Does the charger provide 12V between CP and PE if just sticking the multimeter probes into the CCS plug?

1. At room temperature, after running some minutes, my AR7420 is around 52°C (measured with infrared thermometer). Touching with the finger is okay for 10s, then it hurts. If yours is much hotter, just use a new one. Maybe killed by overvoltage or something. 2. I see no error in your original.pib. I...

The plan is, that the bin and hex files are available at the link https://github.com/jsphuebner/FlyingAdcBms/actions How does this work? Johu configured a "continuous integration job" to the github. This job automatically builds the software and stores the results. Each run is listed on th...
