The information comes from powerdevil and/or Solid, You can try it from the 
command line in a Plasma session (when powerdevil is running):

qdbus local.org_kde_powerdevil  /org/kde/Solid/PowerManagement 
batteryRemainingTime

I think that goes into the upower backend for solid to get actual power 
information, and from there .. you might want to ask in general KDE channels 
(e.g. on IRC in #kde on Freenode) or start chasing through the stack yourself.
