통상적으로, 전기 차량에는 동력원으로 사용되는 배터리는 20~24개 가량 장착되며, 전체 배터리의 무게는 전기 차량의 성능에 따라 달라지나 대개 300 내지 500㎏에 달한다.Typically, the electric vehicle is equipped with about 20 to 24 batteries used as a power source, the weight of the total battery depends on the performance of the electric vehicle, but usually reaches 300 to 500 kg.
따라서, 이러한 배터리의 무게를 지지할 뿐만 아니라 배터리가 요동하지 않도록 고정시키기 위해서 배터리 트레이가 필요하다.Therefore, a battery tray is needed not only to support the weight of the battery but also to fix the battery so that it does not rock.
또한, 전기 차량은 배터리가 전체 전기 차량 무게의 25∼30%를 차지하므로 동력 성능에 많은 영향을 미치고 있는 실정이며, 전기 차량이 부하를 최소로 받도록 배터리를 최적의 위치에 배치하여야 한다.In addition, the electric vehicle has a lot of influence on the power performance because the battery occupies 25 to 30% of the total weight of the electric vehicle, the battery should be placed in an optimal position so that the electric vehicle receives the minimum load.
한편, 500Kg정도의 배터리 트레이(Battery Tray)를 차량에 탑재하기 전에 진단부를 이용하여 배터리 제어부(BMS ; Battery Management System)와 각각의 배터리 사이에 연결된 전압선(Voltage Wire)의 단선 유무를 간이 체크(Check) 한다.On the other hand, before mounting the 500Kg battery tray (Battery Tray) in the vehicle, by using the diagnostic unit to check the disconnection of the voltage wire (Voltage Wire) connected between the battery control system (BMS) and each battery (Check ) do.

도 1에 도시된 바와 같이 전압선(130)이 연결된 상태에서 전기 차량의 진단부(200)를 통해 배터리 팩(120)(Battery Pack)의 내부 단선 유무를 체크하면, 도 2와 도 3에 도시된 바와 같이 각각의 배터리와 배터리 제어부(110) 간의 전압값에따라 전압선(130)의 단선 유무를 확인하였다.As shown in FIG. 1, when the voltage line 130 is connected and the internal disconnection of the battery pack 120 is checked through the diagnosis unit 200 of the electric vehicle, the battery pack 120 is illustrated in FIGS. 2 and 3. As described above, the presence or absence of disconnection of the voltage line 130 was checked according to the voltage value between each battery and the battery controller 110.
도 2는 진단부(200)를 통해 정상적으로 전압선(130)이 연결된 경우 각각의 배터리로부터 평균 12V를 표시하고 있는 정상적인 상태, 즉, 각각의 배터리와 배터리 제어부(110) 간의 전압선(130) 단선이 검출되지 않은 상태를 나타낸다.2 is a normal state displaying an average of 12V from each battery when the voltage line 130 is normally connected through the diagnosis unit 200, that is, disconnection of the voltage line 130 between each battery and the battery controller 110 is detected. Indicates a status that is not present.
도 3은 진단부(200)를 통해 정상적으로 전압선(130)이 연결된 경우보다 약간의 차이값을 표시하고 있는 비정상적인 상태, 즉, 7번, 8번 사이의 전압선이 단선된 상태를 나타낸다.FIG. 3 illustrates an abnormal state in which a slight difference is displayed than when the voltage line 130 is normally connected through the diagnosis unit 200, that is, a state in which voltage lines between the seventh and eighth lines are disconnected.
도 4는 다수개의 배터리 상호간의 전압차를 도시한 도면으로, 전기 차량에 탑재되는 배터리의 개수가 많기 때문에 이들 상호간의 자연스런 전압차가 발생하는 것을 나타낸다.FIG. 4 is a diagram illustrating voltage differences between a plurality of batteries. Since the number of batteries mounted in an electric vehicle is large, it shows that a natural voltage difference occurs between them.
