Re: MLBEvo DBC & LIN Files
Not sure I got it right. You moved the Instruments using vcds and recorded the CAN Düring this? And then play back this recording? This does not help. The vcds uses diagnostic commands (uds on isotp), but you want plain CAN in the car.

Re: QCA7000 Foccci+Clara User thread
Ok, at least the results are stable, that's a good basis for finding the issue. There are two indications, that something with the wiring is wrong: - The CP PWM is reported with 0%. This shows that either the CP is not wired to the charger, or the charger does not provide the PWM at all. - The cable...

Re: First-Time Config of FOCCI And CCS1 vehicle charging
The 0% CP duty is clearly pointing to an error, either of the charger, or of the wiring. First point is to take a multimeter, and measure on the unconnected charger whether there are 12V between CP and PE. Second, check whether the CP of the inlet is connected to the CP pin of foccci. Third, with re...

Re: Use ESP32 Web interface also as GVRET CAN device?
Many thanks for updating the wiki. I also now updated the wifican documentation, and added links to the wiki and to this thread.

Re: Drawing power out of CCS port (V2x, inverse charging, bidirectional CCS)
Physically this exacty is the case. You can charge and discharge. The only blocker may be the software of the car, which could have a supervision that stops the thing. Some results are mentioned above in the thread, the MG is showing how great it could work.

Looks like some good progress. Next steps from my point of view: 1. Find a working serial-to-usb, to get a log file. This would help a lot to understand what is going on. 2. I propose to by a cheap STlink adapter for flashing new software. Flashing via the web interface works often, but sometimes cr...

Re: Drawing power out of CCS port (V2x, inverse charging, bidirectional CCS)
Exactly. If the hybrid solar inverter has a battery voltage range of lets say 200 to 450V, it perfectly matches to a car battery. Somebody uses this here: https://www.goingelectric.de/forum/viewtopic.php?p=2193381#p2193381 He uses an inverter which allows to set the battery type "lead acid"...

Re: Advice on charger for vag batteries
The theory says, that it is not a good idea to charge cells which went below a certain voltage thresholds. Because at low voltage, chemical things happen which cannot be reverted (https://electronics.stackexchange.com/questions/219222/is-draining-a-li-ion-to-2-5-v-harmful-to-a-li-ion-cell) So if the...

Re: Going from 4WD to 2WD with the touch of a button, what is the correct approach
Does it make a difference in consumption to run in the one motor in neutral? I understand, some cars have a mechanical clutch to decouple the motor if not used.

Re: Use ESP32 Web interface also as GVRET CAN device?
No. A blocker on the PC would not prevent the esp from connecting your router. Are you sure your router provides a 2.4GHz wifi, not only 5GHz? Is the router near? Are you sure the wifi name and password is the same as the router expects?

Tested two Tesla Model Y - thanks to the great people in the Linux day in Augsburg! They stop at the PreCharge. Most likely it expects a physical voltage on the port during the PreCharge.

Re: Use ESP32 Web interface also as GVRET CAN device?
This is normal. With pin 37 high, the device is a "Station", it does not publish an own wifi network. It will try to connect your home network, so it does not appear in a wifi list. The only relevant thing is that you provided the right name and password in the credentials file.

Re: First-Time Config of FOCCI And CCS1 vehicle charging
The enable should be 1 from the beginning. Sending enable=0 would terminate the process, so you should always send 1.
In step 8, no ramp down to zero is necessary. Just send enable=0 or press the button on Foccci for 1s. The (fast) rampdown will be done by the charger.

Re: Charging one battery from another as an alternative to parallel packs.
As I understand, the OBCs are step-up-converters, they are able to make a power-factor-correction, following the sinus input voltage of e.g. 0 to 330V and boost it to e.g. 400V battery voltage. Not sure, because our nominal voltage of 230V AC are ~320V peak voltage, and my empty battery has 300V, so...

Re: Charging one battery from another as an alternative to parallel packs.
What about using two buck-boost converters back-to-back, to allow both batteries have any voltage, and the software can select in which direction the current flows. Would allow to use any pack as "range extender", no matter of the nominal voltage or capacity or state-of-charge.
