Abstract
A vehicle battery system and a method of controlling charge of a battery in the system are provided. The system includes a first battery module that has a plurality of battery cells connected to each other in series and a second battery module that has a plurality of battery cells connected to each other in series. The second battery module is connected to the first battery module in series. A controller then monitors a state of charge of each of the first and second battery modules, such that when the state of charge of one of the first and second battery modules is less than a predetermined level, the controller performs active cell balancing between the battery cells of the first battery module and the battery cells of the second battery module.
