Hi! was discussed before: viewtopic.php?f=9&t=4511

That's great
150A and no motion is pretty good, wouldn't even bother to get closer

No communication this time, undo last change... ppvariant is just relevant for calculating cable capacity for type 2 cables. Can't be the culprit. Have you checked your port contactors that they are not stuck? Iso resistance of port? Does CP measure fine seen from the port? Test also with ActuatorTe...

Yes exactly. PE should be solidly connected to the chassis not far away from the charge port so that would serve as a ground reference for the signals

I guess the design is still young enough for shuffling pins

Via the A/C inverter it will just boost
Via MG1 it will just buck. You need an additional relay to connect the battery to the buck side while charging. At least then you don't need the extra current sensor because it will use the MG1 ones

So charging feature would work but not powering the dcdc converter while driving.

Good news, I also bought one of those 2nd hand from someone who went a different way. So I have both hardwares. Is it version 1.3? Early versions don't have the user PWM connection. Stupid question, how does it know whether it's in charge mode, and is charge mode also what happens during regen? Bec...

The booster is limited to 100A, so this will get you 10 kW

The order has gone through now, I'm excited! On another note I wanted your input on this. Here is the current pinout: focci_pinout.jpg The two contactor outputs are on different plugs. The LEDs and button are not on the plug that is more charge port oriented but on the car oriented one. Now I though...

Also, does any of what you described require using new pins or telling the buck/boost what to do? Any code or software? Or does it just happen by being connected? Sorry, just found this. With the SMT version of the Prius controller this is integrated. In drive mode the "user PWM" pin runs...

I like to use my cheap Chinese grid tie inverter

screen capture would help. Is it the new "green" interface or the old "white" one?

Yes I see it now and no that will not cause an issue

Yes indeed. It's 28€ just for the QCA chip and like 20€ for the remaining board :) Order went wrong. Went through till payment, then suddenly jumped to order history. Cart and history empty :( Couldn't start over because the QCAs are now stuck in the zombie order. Meh, they'll figure it out. I have ...

Veeery nice! Udo will like that.
I think you have the book, right?

Maybe you can be somewhat compatible? But don't want to restrict you Attached some notes also, but the table from the book is more up to date

Very tidy install and great re-use factor!
Are you using the stock battery-to-drivestack cable as well?

Another milestone reached today. I ordered 10 QCA7005 chips to JLCPCBs factory and can now select it for assembly :) They are a bit expensive at 28€ a piece but that is better than loosing chips to nasty soldering, let alone the time this consumes. So this quantity will appear in the shop in about 2...

First cut of a breakout board with mini mainboard for first tests

Good luck! Various proprietary solutions exist, would be nice to have an open source one

No, this is just needed for actual resolvers as they output like +/-1V. Your chip likely outputs between 1-3V or something, so unipolar already

Great to read :) That's very strange as I'm running the inverter (on a Zoe motor) without the mod. I even faintly remember that the pin drew excessive current when feeding it 12V. Another user reported the mounting holes to be off and they fit my inverter perfectly. I wonder if there's different rev...

Just tried opening the project and there seem to be some missing files: Fehler traten beim Laden der Footprints auf: Footprintbibliothek "/home/johu/Projekte/e-umbau/kicad/Nissan-Leaf-Gen-3-Adapter-Board/V0.0.4/Footprints" nicht gefunden. Footprintbibliothek "${KICAD_LIB}/JLCPCB/JLCPC...

Now continuing with some more gate driver research. The isolators are ISO7421 from TI. https://www.ti.com/product/de-de/ISO7421 They have one forward one reverse channel. Traced the 6 forward channels that gives me the 6 gate drive signals and the 6 reverse channels give me the 6 desat signals. The ...

Thanks very much for writing this up - again.
