Ubuntu having two power tools which can work efficiently through terminal and can give you complete information about your power statistics, they are powetop and powerstat. you can install them with

sudo apt-get install powertop


sudo apt-get install powerstat

To run powertop you must be root user , so run it as sudo.I mean

sudo powertop

Then you will see ( captured in my PC , usually No battery :P , just for Idea )

enter image description here

powerstat you can run as normal user also , it will provide the complete status information of the battery.

hope that helps you about Command line power monitoring tools.
