System and methods for balancing a vehicle battery system are presented. In certain embodiments, a method for balancing a vehicle battery system including a plurality of sections may include calculating a plurality of quanta of energy required for each of the plurality of sections to reaching a balancing point. Based at least in part on the calculated plural of quanta of energy, it may be determined that the plurality of sections of the battery system are unbalanced. To balance the battery system, a balancing system may be selectively actuated to change the amounts of energy stored in one or more of the plurality of cells such that the plurality of quanta of energy are within a particular range.
