Re: MEB Chargers
The VCDS does not translate the raw CAN messages. The process is like this: - For example, SavvyCAN (or the real car) sends a CAN message with the intended charge current. The sender would be the BMS in this case. Let's say this is byte 1 of the CAN message with ID 345 (just as an example). - The ch...

Re: MEB Chargers
Assume we have a log of a working vehicle, which includes the start of the charging session. If we are lucky, we could replay this log against a single charger, and the charger would react. Of course before replaying, we removed the messages which are coming from the charger from the log, to avoid c...

Re: GS450h Transmission and Inverter Loss of drive
Maybe it would be helpful to create a time plot of the interesting spot values, to understand what is happening first and what next. For example to see the throttle increasing during slowly pushing it, and observe the torque and speed during this.

Re: [DRIVING] VW Touran powered by Nissan Leaf [FINISHED]
It was around 120km in my case. I was hoping, that the way bigger battery has much less resistance, so that the heat produced with guessed 20kW highway cruising is negligible. Are there any data sheets available for the ID battery regarding the resistance and heat capacity? This would allow some sim...

Re: [DRIVING] VW Touran powered by Nissan Leaf [FINISHED]
The temperature increase while just moderate driving is surprising. Maybe there is still unintended resistance in the module connections (oxide, missing screw torque?). For comparision, my also air-cooled Ioniq, which has a quite low temperature increase while highway driving in summer. The blower o...

Re: Open source CCS using AR7420
Not sure what you intend to do. Two EVSEs on the same line will destroy the PWM duty and the 12V level. So the real car will not start the communication most likely. And the real charger will most likely detect wrong CP voltage levels and deny charging.

Yes, two different "languages". The VCDS talks UDS, the real car environment talks plain CAN. Yes, CAN logs of a working vehicle are a good starting point. So find out the part number and software version (should be visible in VCDS), and find out in which vehicle versions the charger is us...

Re: charging station / wallbox hardware basics
Use an oscilloscope to check whether the EVSE transmits the homeplug coordinator packets. These should be strong (several volts) directly on the modem, a little bit weaker on the CP line (because of the serial resistor) and more weaker on the PEVs modem (because double resistors).

Re: charging station / wallbox hardware basics
Did it also needs 150 ohms? Yes, I recommend to use the resistor on both, the PEV and the EVSE. It prevents damaging currents. A possibility for the PEV side is shown here: https://github.com/uhi22/pyPLC/blob/master/doc/hardware.md#dieterlv For the software part, did I need to set PEV MAC address m...

Re: WTB: Standalone Eltek charger controller
Maybe we can just turn this discussion into an technical discussion about your Eltek, to collect data and ideas. Do you have data sheets, protocol descriptions or something like this which you could share?
And this maybe Johu could shift the thread into a more appropriate sub-forum.
