A system includes a battery pack designed to store electrical energy at a rated voltage and having a first and second battery module, each having a plurality of battery cells, and at least one switch selectively coupled to the battery modules. The system further includes an on-board charger that receives electrical power. The system further includes an ECU that determines a current voltage of the battery modules. The ECU also controls the at least one switch to transfer the electrical power to a combination of the battery modules until the current voltage of the first battery module or the second battery module reaches the rated voltage. The ECU also controls the at least one switch to transfer the electrical power to the first battery module when the current voltage of the first battery module is less than the current voltage of the second battery module.
