For prototyping's sake, you can do something like:
while true; do grep whatever /sdcard/bat_log.txt > \
/sys/kernel/debug/ieee80211/wlan0/mesh_params/alm_batt.txt
done
i.e. writing that file would update some state that the ALM calculation
uses.
If you want to do something more permanent, then maybe you can
directly read the battery details from some platform device, but
that will be pretty platform specific.
