Abstract
A method for performing supplementary charging on a low-voltage battery based on redundancy power conversion, includes: determining whether supplementary charging is required for a first low-voltage battery or a second low-voltage battery in a parked state; determining whether supplementary charging mode entering using a voltage of a high-voltage battery is possible when it is determined that the supplementary charging is required; and converting and supplying a charging voltage of another low-voltage battery to a low-voltage battery that requires supplementary charging among the first low-voltage battery or the second low-voltage battery when a condition that does not allow the supplementary charging mode entering is determined.
