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

Re: Doing useful things with the Prius Gen2 buck/boost converter
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...

Re: Develop a QCA7000 board?
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...

Re: Doing useful things with the Prius Gen2 buck/boost converter
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...

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

Re: Develop a QCA7000 board?
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...

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

Re: i3 controller hacking from diyelectriccar.com
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 drew this up for a customer so thought I might as well post it here. Pain: you have no VCU and no CAN communication with the inverter but want to limit throttle for whichever reason. Solution: limit max throttle output voltage with a shunt reference (or Zener, but they are less predictable I th...

Sound like a cause for failure? No, 5V pins are on many other connectors. Can you please attach pictures directly to your post (attachment in Full Editor).

Re: First-Time Config of FOCCI And CCS1 vehicle charging
Gain=0 and x*0 is 0 Make Gain=1 and you'll get your data
In the diagram it looks like you're feeding 5V to Foccci? This is not necessary
The CCR might be redundant as the driver chips are quite strong, lets say 5A total contactor current (limited by reverse protection diode)
