USB PD battery charge level for Orin/Thor

Robotics & Edge Computing Jetson Systems Jetson AGX Orin

Hi, I’m testing USB PD battery packs with AGX Orin Devkit, this might also useful in future for Thor owners too, although afaik there’s not commercial OTS Battery pack with 140W right now.

You can get data from PD about voltage/current/etc in /sys/class/power_supply/
Most crucial info for me (and probably everyone else) is to get battery charge in %,

There are some info here:

This probably needs cooperation from battery manufacturer’s side too, but I’m willing to message them, or otherwise order some USB PD controllers to play with, and write some open source code.

I believe this can be very useful for Nvidia Jetson community since it would be easier to integrate Off the shelf battery packs for robotic systems with Nvidia Jetson.

Thanks!

I guess the question I had for the community is:

Did anyone successfully developed anything with USB PD with Jetson/Else, specifically with the Battery_Status?

Hi i_love_nvidia,

What’s the Jetpack version in use?

Sorry that we don’t have related experience about using “USB-PD battery packs” on Jetson device as there’s no battery on the devkit by default.
You may request the vendor of the battery for the usage and we could help to check how to configure the kernel or device tree on Jetson to enable it.
