Change capacity level in uevent.


I am trying to figure out what is the purpose of the capacity level attribute for batteries. On my laptop, It only have two states: normal and full. Is it possible to make it change a little bit more depending on the capacity of the battery (for example: full, almost full, normal, low, almost empty)?

I tried to set a udev rule:

KERNEL=="BAT1", SUBSYSTEM=="power_supply", ATTR{status}=="Discharging", ATTR{capacity}=="[4-8][0-9]", ATTR{capacity_level}="Almost_Full"

but it did not work (but  also tested if the rule is triggered and it is, so I assume that the problem is not the conditions for triggering the rule)

Do you know if this is possible to do?
Thank you for your help.
