Yes a logical next step would be to pair this to a hybrid PV inverter or something

​​@@EngineersFearI was thinking the same thing, there are hybrid inverters that support these voltages

theoreticly you can pair it with a hybrid inverter. and very probably it would work but don’t forget that most hybrid inverters have no galvanic isolation and that could be a safety risk. Use a galvanic isolated bidirectional charge module instead. like this one to exchange energy from homestorage and car: BEC75025 or this one to directly go to AC: BEG1K075G

@@mizettelzettel I would expect there to be a DC/DC converter with isolation transformer between battery and grid - also to increase the input voltage range

@@EngineersFear true maybe you are right, i thought they don't do it due to efficency reasons like in the bigger industrial ones. (blueplanet SMA trumpf) and in most of the hybrid i have read inverters its mentioned in the datasheet that you cannot use multiple inverters on one battery. I was assuming its because they are not isolated. Ah but maybe its just because it doesn't work with the power limits of the battery. Ok then that would be really cool to have it directly on the inverter :D Would be interessting if someone can get the inveter to do the precharge phase for the model 3. otherwise we need some sort of isolated software adjustable high-voltage low-power supply that can do it.

That's very good news! I rely on the voltage reported by the charger. Have the voltage measurement ready but never bothered to actually hook it up ;)

Great. Did you use pyPLC or something else as charger? Any chance to record a pcap?

That is a very good result, congrats. It would be amazing if Tesla just provided V2G or V2L for all of their new vehicles. If the Model Y is capable of V2G with a software update, I would definitely buy. I am glad they pushed the envelope with the best-of-breed technologies on the CyberTruck. We have NEM3 in California as of 2024 and PG&E will pay a high price for electricity at certain times of the month and specific hours. You need to know these hours and be able to feed back to the grid from your batteries to take advantage. It is all about capitalizing on this opportunity or getting screwed over by high electricity rates. I think this would be bring more value from your Tesla. I don't drive a high amount of miles and would benefit from V2G or V2L. Love to see the tech folks push the envelope.

@@ReddyToGo. yes pyPLC, sorry i didn't recorded pcap. i canged my setup to non bidi at the moment, and i don't have time to do it again at the moment. i only have some grafana graphs from the homestorage where i can see the power flow from the past.

Thank you. Yes, totally overcomplicated.

Let's turn it the other way around: Goal is to use the current model Y - and not only that. Not waiting that somebody will hopefully do something in the future.

@@ReddyToGo. That is obvious. For my user case Im looking forward for Tesla to implement it in the near future

of course 😄 github.com/uhi22/pyPLC/

Thank you. I am gonna take a look at it. A video on how to get this code running on a raspi or similar would be great.

At least it should get it to the next step where it closes the port relays. Next question is, how long does it keep them closed when it doesn't detect charge current?

Answer: you can "extract" 5kWh from a Tesla before it closes the session with an error :)

​@@MastroGippoThat's not bad, how do you know that?

I did it

@@MastroGippo Great, did you need to apply physical voltage during precharge? Do you have a pcap or other log?

Sagen wir mal NOCH nicht ;)

Mega Projekt respekt :-) Drücke die Daumen das es alles läuft ;-)

@@EngineersFear Hab ein Update vom openV2Gx gepusht. Wäre cool, wenn das nochmal jemand am Model Y testen könnte. Oder jemanden kennt in Bayern wo ich das mal testen könnte...
