Abstract
A vehicle system includes DC/DC converters configured to receive electrical currents from high voltage battery modules and output regulating electrical currents to a low voltage battery. The vehicle system includes a control system coupled to the DC/DC converters, the high voltage battery modules, and the low voltage battery, where the control system is configured to control the DC/DC converters to recirculate one or more of the electrical currents back to one or more of the high voltage battery modules in order to balance states of charge in the high voltage battery modules.
