I just recently purchased the 48V Version of the odrive to power a small electric vehicle.
Really love the feature to power two motors from one board. Closed loop yaw control really makes a difference in driving dynamics!
I used Benjamin Vedders VESC before and hope to get a little better control with the odrive, mainly due to the encoders used. Yeah, I know that the VESC also supports encoders, but they have always worked a little sketchy for me.
Long story short, I was hooking up all the electronics last night. I guess I was a little tired, as I hooked up my battery (~36V LiIon) to the AUX Channel where the braking resistor goes, polarity was not reversed though. Visible results are a blown 30A Fuse in my Battery leads and a hole in one of the DRVs.
If I understand the schematic properly, current should be going from the AUX+ through the body diodes of the High Side MOSFETS to the DC Link and should then be charging up the DC Caps.
Should neither cause excessive current flow nor any other problems, right?
I checked all current rails on their own:
3V3 is fine.
5V seems to have a short to GND with ~3Ohms
DC Link, dont know, because the DRV 5V Buck causes problems obviously.
Changed both DRVs, no change in symptoms.
I am currently lack Ideas what the Issue could be?
Bests and thanks,
