Re: Develop a QCA7000 board?

Good question, did anybody find a reasonable priced source in the meanwhile? (I'm dreaming of below 10€)

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.

Great, congratulations! - The "maxPower" parameter didn't seem to stop me from setting voltage/chargeCurrent to values exceeding the set max wattage. - MaxVoltage didn't seem to prevent me from setting target voltage higher (did not prevent the output power) - MaxCurrent did not prevent me...

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: Open source CCS using AR7420

Normally there should be no need to "call .ino files" and "adding header files". The arduino IDE should automatically treat the ccs32.ino as main file and show all the files in the project, without the need of calling or adding something. The only arduino-specific things need to ...

Do you talk about this: [705380]? This is not a "log value numbering", this is the time since Foccci was powered-on, in milliseconds.

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 ...

Trying to support DIN and ISO in one software runs into out-of-memory (RAM and ROM) at the moment. https://github.com/uhi22/ccs32clara/tree/iso-test

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.

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

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...

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

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:

This keeps a single file forever, and cleans up multiple ones.

Re: Save parameters to flash returns ok but params not stored.

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?
