Hello,

I am trying to use a battery pack that will plug into the barrel jack of the 4G Jetson Nano Developer Kit for a project that requires it to be portable.

My question is, how do I measure the battery percentage if it is possible, so that I can send a notification out from my Nano when the battery is low?

I have been having a hard time finding a solution or workaround for this situation, so any information or ideas will be very helpful.

Kind regards,
Paul

hello paulamoruso,

please check /sys/class/power_supply/, there should be a sysnode called BAT, please check capacity for the battery percentage.

It seems there is nothing under power_supply.

Any ideas on what I should do about this?

Thanks again,
Paul

hello paulamoruso,

please refer to Jetson Nano Product Design Guide,
did you use module pin PMIC_BBAT to enable Nano’s power?
