I have quite a few homebrewed ones, and if I recall the PH2 has one or two charging feats.
Here are my homebrewed ones:
IMPROVED CHARGE (General, Fighter)
You are extraordinarily accurate when you charge.
Prerequisites: Base attack +1
Benefit: When you charge you get a +1 competence bonus to hit. (This stacks with the normal bonus from charging.)
________
MASTERFUL CHARGE (General, Fighter)
Your charges are incredibly powerful.
Prerequisites: Base attack +4, Improved Charge, Run
Benefits: When you charge, you can move three times your normal speed. Your threat range increases by one while you charge (this stacks with all other threat range increasing feats and effects).
________
SUPREME CHARGE (General, Fighter)
You can attack those near the line of your charge.
Prerequisites: Base attack +10, Improved Charge, Masterful Charge, Run
Benefit: Whenever you charge you may take an attack of opportunity on any one enemy within reach at any point before the last 10’ of your charge. All your charge bonuses apply to this attack of opportunity.
________
BREAK THE LINE (General, Fighter)
Your charges can break an enemy line.
Prerequisites: Base attack +13, Str 13+, Improved Bull Rush, Improved Charge, Masterful Charge, Power Attack, Run
Benefit: When you charge and attack an enemy in a square adjacent to another enemy, if your attack is successful you may make a free bull rush attempt on all enemies in squares adjacent to the one you attacked. If the squares they would occupy at the end of the bull rush are occupied, they fall prone in those squares.
