Please do this, it will go a long way in helping us, who can not as yet afford an AC motor, achieve the EV dream.

Tuned in and hoping for an update. This project has a lot of potential if it succeeds.

Does this mean MUU,MVU and MWU will be fed with the same pwm signal?

Watching this for a reply as well. Would be interesting to know the capabilities of having u,v &w combined into one output.

This is impressive work, I'm inspired.

Good day, I have a question thus slightly off topic. Has anyone made any effort to look into Ground fault detection or Loss of isolation fault monitoring in the Gen 2 inverter?

More testing of the I-10 (12) "UDC"/"V" output, all measurements with internal 12v "ON" and "vdc":

I10-12 @ Buss vdc
0.533 @ 0.00
0.873 @ 56
0.990 @ 75
1.120 @ 96
1.453 @ 150
1.490 @ 156


From lack of things to do, I tried to find the most linear relationship between these points and this is ...

Pin #1 is labeled IGCT and is Ignition on according to this attachment.

NODD and VLO are the ones giving me a headache at the moment because I don't have anywhere to test them.

Trying to upload a few pages of what I found. Is there a way we can share the Toyota manuals or it's illegal? For now just trying to upload screen shots of C5 connector signals.

You're right they look very familiar. Good Lord makes my version of how to control the motor look pedestrian.

This is going to be interesting.

Good day, just stumbled upon this thread. I am curious about how you were able to control a DC motor using the Prius inverter.

It was written above:
Its a mash up of a couple of Damiens designs. The simple DC controller generates the PWM for the motor, and the board layout is from the Prius ...

Been a little while since my last update, but made a bit of progress.

Added some conduit under the car for the rear battery cables:

Got it back on 4 wheels and ran the E46 on a 12V battery and achieved 'First Roll'!

Meanwhile the PCBs turned up for ...

Is there a chance of you posting a schematic of how the high voltage junction box is wired.
