A list of different charger types, with their minimum supported voltage, is available in the wiki: https://openinverter.org/wiki/CCS_Fast_ ... (Overview)
The most critical is the Tesla Supercharger, which rejected requests below 230V.

Hi, sorry to hear this.
Seems we have some inconsistent information about the intended supply voltage range.
The protector diode (U5, TVS, SMAJ16A) is designed for operating voltages up to 16V, will start current draw between 18V and 20V. Data sheet: https://www.littelfuse.com/assetdocs/tvs-diodes ...

Added the feature "pretended cable check". It can be configured to be
"no", so doing a real HV cable check (option A above) or
"yes", which just does nothing but reports "cable is ok".

git commits https://github.com/uhi22/pyPLC/commit/26aef0d132421442c0e868df914ab8ce29dd4021 and https://github.com ...

Do you use a voltage measurement board, to give the beaglebone the possibility to know the physical voltage? If not, then turning on the boost converter during cable check does not make sense, because we can anyway not measure the voltage. So option B is the way to go.

That is half-way good news. Congratulations that you got it running so far.
The error message comes from the situation, that during cable check we want to apply a voltage to the HV pins, and physically want to read back this voltage. This is to confirm that there is no shortcut between DC+ and DC ...

Ah, das ist die Variante mit dem Buck-Converter. Der Aufdruck "5V" ist falsch. An dem Pin kann man extern Spannung einspeisen, 7 bis 20V (die geht dann über D11 zum Buck-Converter, der 5V draus macht). Wenn man die ganze Baugruppe aber eh mit 5V versorgt, also 5V an P9_5, ist die Einspeisung an ...

This depends on the board version. I only have a quite old board, this has the "VCC" of the phoenix connector connected to the 5V line. (Also my board has manual patches, not sure whether all boards have this). As I understand, the newer boards do not have a 5V on the phoenix connector, they have a ...

I'd even propose to NOT close the feedback loop in the way to post the summary into the forum. I'd propose to review the result, and only if it contains wrong ideas, to add explanation to the original source (GitHub). Because: The next time somebody asks the AI a similar question, it will come to ...

The wiki is talking about 2s or 3s timeout https://openinverter.org/wiki/Foccci
Any chance to log the CAN traffic, to understand whether there are such long gaps in the communication?

Sounds like 80 cells (16*5).
The ground fault is strange. Does the inverter produce lot of high frequency AC swing on the DC lines? Then maybe the capacitance between battery and chassis leads to AC current. You could make some experiments with the Touran, adding some nano or microfarads between DC ...

Which target current? No idea where negative Target current should come from, hmm.
Congratulations for the ID.4 success, hopefully you can trick it to play, and it is not too nervous about negative charging currents.

Seems you missed to update the OpenV2Gx. The cableCheck response does not show the intended
DC_EVSEStatus.EVSEStatusCode = dinDC_EVSEStatusCodeType_EVSE_IsolationMonitoringActive;

Just for the records: Some guy recorded pcap files while running Chinese Elejoy CCS-to-AC adaptor. https://teslamotorsclub.com/tmc/posts/8602625/
Not a big surprise, they are also using the good old DIN spec like we do with pyPLC.

Which hardware setup do you use to capture the communication with wireshark?

Progress: Integrated the stop-button in pyPLC and in the setup description.

The only way to find out whether this adapter works is to try. I see the risk that the fast adapters use a different, incompatible chipset.

Using 3 PLC nodems on one CP line works, but sniffing the complete traffic does not. The sniffer only forwards the broadcast traffic (first SDP) but nothing ...

Success on the Ioniq (not a big surprise ).
But how to stop it? Suddenly noticed that I have no stop button, neither in the car nor on the discharge box. Finally pulled the banana plug of the CP line, this worked as intended.

Feature update of the demo box:
- pyPLC controls the precharge voltage
- pyPLC sends the measured HV to the display in all states
- display shows the log file number (so that for testing it is easier to match the pcap file to the actual test situation, just by making foto/video of the test session ...

The Hyundai/KIA platform (Ioniq5, 6 etc) has the OBC in the "famous" ICCU, and it has fuses in the AC lines. Picture and schematic here: https://www.goingelectric.de/forum/view ... 7#p2406347

Progress with the demo box:
- Adjustable HV, consisting of a bunch of small DCDC converters, which are controlled in groups by 5 FETs.
- HV measurement using the muehlpower board
- supply by two 18650 cells and a circuit board from a power bank to get 5V
- relay to connect/disconnect the bulbs

Ali delivered a quite solid CCS plug. Adding 10A 1000V DC PV fuses directly in the plug.

This looks like out of spec. For starting the high level communication with the car, the charger shall apply 5% PWM, and only then the car shall send the slac request. With 50% PWM the car shall use classic low level comm only.

Isn't the service disconnect normally in the middle of the battery, to cut the HV into two halfes?

Does it apply 5% PWM together with the PLC? And does it fall back to higher PWM afterwards?

FoccciCape &Co are moving to their new home Plan is to integrate a controllable step-up for precharge and HV measurement.
