According to the present invention, an operation method of a vehicle battery system comprises: a step where a high-voltage battery supplies high-voltage direct current power to a first electronic component according to control of a control module when a charging capacity of a low-voltage battery is a threshold value or less; and a step where the low-voltage battery supplies low-voltage direct current power of the low-voltage battery to a second electronic component according to control of the control module when the charging capacity of the high-voltage battery is the threshold value or less. The present invention can increase energy use efficiency of a vehicle battery.

    본 발명의 차량 배터리 시스템의 동작 방법은 저전압 배터리의 충전 용량이 임계값 이하인 경우, 고전압 배터리가, 제어 모듈의 제어에 따라, 제1 전장 부품으로 고전압 직류 전원을 공급하는 단계; 및 상기 고전압 배터리의 충전 용량이 임계값 이하인 경우, 상기 저전압 배터리가, 상기 제어 모듈의 제어에 따라, 상기 저전압 배터리의 저전압 직류 전원을 제2 전장 부품으로 공급하는 단계를 포함한다.
