Re: Can Bus question
It would be helpful if you describe your observed behavior and expected behavior. E.g. nothing is shown on your display, or values are arriving but with wrong values or missing completely or start ok and later are stuck or or or.

Re: Reverse engineering OEM Hardware
Looks good. Just wire CANH, CANL and ground to the wifican and add a 12V supply. Then clip it to a CAN and show us what you see. What is missing?

Re: The motor turns in the opposite direction
This leads to the next question. Which is the expected behavior? (E) It is normal, that the angle spot value changes multiple times from 0 to 360°. Because the angle is a "virtual angle" which counts per (resolver?) pole pair, not per physical revolution. (F) During one physical revolution...

Re: Reverse engineering OEM Hardware
So, I got my CANcrocodile, along with an ESP32-S3-Pico board. My wonderful friend CHATgpt just doesn't seem to be able to dumb things down enough for me to create an interface to use the CANcrocodile to sniff the CAN Bus. Did not get the point where you are stuck. Do you have the CAN hardware runni...

Re: The motor turns in the opposite direction
There is confusion, maybe due to the translation. Which of the statements is true? (A) The motor is spinning in the opposite direction. You select forward, and it moves backwards. You select backward, and it moves forward. (B) The car always moves backwards. You select forward, it moves backwards. Y...

Re: Type 2 to CHAdeMO Converter/Charger?
There are also 11kW public chargers, and drawing 22kW from them could blow the fuse. Means: evaluating the PWM makes sense.
And: There are public chargers with fix cable and plug. Means: Having a type 2 socket in the charger gives more flexibility.

Re: Dacia Spring 27 kw and Fronius Symo Gen 24
For the beginning, find out how many CAN busses go to the battery (hopefully 1). Find out the baud rate (with oscilloscope). Record some CAN traces (savvycan). Eg recording a complete short charging session and a short drive.

Re: First-Time Config of FOCCI And CCS1 vehicle charging
It does not help to try random things. The goal is to find the root cause, why the PP resistance is not 150 ohm. This is a simple resistance measurement, where not much can go wrong. Theres a certain chance, that fixing this issue could also fix the failed cablecheck. To find the issue with the PP r...

Re: First-Time Config of FOCCI And CCS1 vehicle charging
There are physical connection issues. Back to 8th of May: 2. When plugging and unplugging, you should see in the web interface resistanceproxpilot changing between 10000ohms (means infinite) to whatever your charger has. 3. If nothing helps, disconnect everything, use a resistor (something between 1...

Re: First-Time Config of FOCCI And CCS1 vehicle charging
I use Putty on windows10 for logging, this adds nice wall-clock time and date at the beginning of each session. And if you repower the foccci before plugging in the CCS, you also get fresh time stamps of clara, starting at zero milliseconds. Both helps a lot for orientation.

Re: Develop a QCA7000 board?
The plan is that Clara announces both, DIN and ISO2013, and the charger selects what it likes. I do not plan to remove the DIN support. For testing, there is a parameter to force DIN or ISO, but in the end the "both" setting will be the usual way.

Re: Develop a QCA7000 board?
At the moment, Foccci/Clara only support the DIN schema for the high level communication (din:70121:2012). This is fine for most use cases. However, the limitation of the DIN is, that the maximum voltage is 500V, reported by the charger. To use higher voltages, we need to step to the ISO15118, which...

Re: First-Time Config of FOCCI And CCS1 vehicle charging
Found out, that the ISO1 (aka ISO 2013) needs less ressources, and also KIA EV6 uses this schema, so it should be fine for us. Now it fits. In case someone needs the ISO2 (aka ISO 2016), a bigger controller is necessary. What a crazy thing. [Edit] We are off-topic here, so let's discuss the DIN/ISO ...

Re: First-Time Config of FOCCI And CCS1 vehicle charging
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.
