In the present invention, when a resistance value of the insulation resistance is large, an insulation resistance measurement unit controls the first insulation measurement switch in an on state to measure the insulation resistance of a battery through a first insulation measurement resistance unit. When the resistance value of the insulation resistance is smaller than the previous case, the insulation resistance measurement unit controls the second insulation measurement switch to be in an on state and measures the insulation resistance of the battery through the second insulation measurement resistance unit. As described above, according to the present invention, since the insulation resistance is measured for each section (that is, a section having a large resistance value of the insulation resistance and a section smaller than this) according to the resistance value of the insulation resistance, the insulation resistance is measured. Therefore, the safety of the vehicle and vehicle occupants can be ensured, and the insulation resistance of the battery can be measured with relatively high accuracy.

    본 발명은 절연저항의 저항값이 큰 경우에는, 절연저항 측정부가 제1 절연 측정 스위치를 온 상태로 제어하여 제1 절연 측정 저항부를 통해 배터리의 절연저항을 측정하고, 절연저항의 저항값이 앞선 경우에 비해 작은 경우에는, 절연저항 측정부가 제2 절연 측정 스위치를 온 상태로 제어하여 제2 절연 측정 저항부를 통해 배터리의 절연저항을 측정한다. 이와 같이, 본 발명에 의하면, 절연저항의 저항값에 따라 구간(즉, 절연저항의 저항값이 큰 구간 및 이보다 작은 구간 등) 별로 절연저항의 측정이 이루어지기 때문에, 차량 및 차량 탑승자의 안전을 도모할 수 있음과 동시에, 배터리의 절연저항을 비교적 높은 정확도로 측정할 수 있다.
