To use them just open the console command section (this varies depending on your region in some cases) and then type in bat and then one of the 3 commands as shown below;
xpsmall - gives 250 XP
xpmed - gives 1000 xp
xplarge - gives 2500 xp
The reason why these commands are used is so that you level up and still get the perk points, unlike some other commands, they are in 3 different versions just incase you want a slight boost.
WARNING: If you use the xplarge command on a new character there is a chance you will not get all the perk levels, to be on the safe side use the xpsmall command for a few levels then move up.
