The present invention relates to an apparatus and a method for charging a battery of an integrated inverter system, wherein the apparatus comprises: a battery unit storing a first voltage; a charging unit supplying a second voltage for charging the battery unit; an inverter unit receiving the first voltage from the battery unit in a normal mode to drive a motor and charging or discharging the battery unit by depressurizing or boosting the second voltage supplied from the charger unit in a charging mode; and a control unit controlling the inverter unit in the normal mode to drive the motor, determining whether the second voltage is reduced or boosted in the charging mode, and controlling the inverter unit based on determination results to reduce or boost the second voltage to charge the battery unit. The present invention simplifies a battery charging system of a vehicle by charging the battery through the inverter, and it is possible to secure a space by reducing the size of electric parts.
본 발명은 통합 인버터 시스템의 배터리 충전 장치 및 방법에 관한 것으로서, 제1 전압을 저장하는 배터리부, 배터리부를 충전하기 위한 제2 전압을 공급하는 충전부, 정상 모드에서 배터리부로부터 제1 전압을 공급받아 모터를 구동하고, 충전 모드에서 충전부로부터 공급되는 제2 전압을 감압 또는 승압하여 배터리부를 충전하는 인버터부, 및 정상 모드에서 인버터부를 제어하여 모터를 구동시키며, 충전 모드에서 제2 전압의 감압 또는 승압 여부를 판단하고 그 판단 결과를 토대로 인버터부를 제어하여 제2 전압을 감압 또는 승압함으로써 배터리부를 충전시키는 제어부를 포함하는 것을 특징으로 한다.
