Abstract
This disclosure describes vehicle systems and methods for controlling charging of an auxiliary (i.e., low voltage) battery of an electrified vehicle. Exemplary charging methods may dynamically adjust a low voltage setpoint of a power converter during the low voltage support. The proposed systems and methods therefore achieve constrained low voltage support by controlling the power drawn by the power converter at an appropriate level during the low voltage support.
