Description

전기 자동차의 배터리 트레이{BATTERY TRAY FOR ELECTRIC AUTOMOBILE}Battery tray for electric vehicles {BATTERY TRAY FOR ELECTRIC AUTOMOBILE}

본 발명은 전기 자동차의 배터리 트레이에 관한 것으로, 보다 상세하게는 전기자동차의 배터리 트레이에 구비된 휴즈의 교환을 안전하고 빠르게 교환할 수 있는 전기자동차의 배터리 트레이에 관한 것이다.The present invention relates to a battery tray of an electric vehicle, and more particularly, to a battery tray of an electric vehicle that can safely and quickly replace the exchange of the fuse provided in the battery tray of the electric vehicle.

일반적으로 전기 자동차는 에너지 저장장치로 배터리를 사용한다.In general, electric vehicles use batteries as energy storage devices.

이러한 전기자동차는 약 12V 모듈 단위로 생산되는 배터리를 직렬로 연결시켜 높은 전압을 발생시키게 된다. 이때 사용되는 모듈의 개수는 필요 전력량에 따라 상이하나 일반적으로 250V에서 350V 사이의 전압을 이용하게 된다. 12V의 배터리로 이 같은 높은 전압을 내기 위해서는 20~30개 정도의 배터리 모듈을 직렬로 연결하여 사용하게 된다.Such electric vehicles generate high voltage by connecting a battery produced in units of about 12V modules in series. In this case, the number of modules used varies depending on the amount of power required, but generally, a voltage between 250V and 350V is used. To produce such a high voltage with a 12V battery, 20-30 battery modules are connected in series.

상기와 같이 다수개 연결되는 배터리를 배터리 팩이라 하며, 이를 배터리 트레이라 칭하는 외부 케이스에 배터리 시스템을 구성하는 다른 전장품들과 같이 위치시킨다.A plurality of batteries connected as described above is called a battery pack, and the batteries are placed together with other electrical components constituting the battery system in an external case called a battery tray.

또한 도 1에 도시된 바와 같이. 상기 배터리 직렬 연결의 중간단 즉, 배터리 트레이(1)의 상면에는 휴즈(3)를 장착하여 과전류가 흘렀을 경우 배터리 및 그 주변기기를 보호한다.As also shown in FIG. 1. A fuse 3 is mounted on an intermediate end of the battery series connection, that is, an upper surface of the battery tray 1 to protect the battery and its peripheral devices when an overcurrent flows.

그러나, 배터리 트레이의 제작공정은 먼저, 배터리 트레이 내부 전장품들을 조립 후 차량 바디 아래에 차량을 리프트로 들어올린 후 배터리 트레이 리프트를 올리면서 차량에 장착하는 것으로서, 그 조립 공정이 상당히 복잡하다. 이에 따라, 휴즈는 배터리 트레이의 상면에 장착되어 있음으로써, 배터리 트레이에 문제가 발생하여 배터리 트레이를 탈 장착할 경우 작업자는 300V 이상의 고전압에 노출된 상태에서 작업을 하게 되어 상당한 위험이 따르고 휴즈를 갈아 끼우는데도 배터리 트레이 전체를 내려야 함으로 상당한 시간과 작업량이 요구되는 문제점이 있다.However, the manufacturing process of the battery tray is, first, assembling the electrical equipment inside the battery tray, and then lift the vehicle under the vehicle body as a lift and then mount the battery tray lift to the vehicle, the assembly process is quite complicated. As a result, the fuse is mounted on the upper surface of the battery tray, so when a problem occurs in the battery tray, when the battery tray is detached and a worker is exposed to a high voltage of 300 V or more, the worker is exposed to a high risk, and the fuse is changed. There is a problem that requires a considerable amount of time and work because the entire battery tray must be lowered.

본 발명은 상기 전술한 바와 같은 문제점들을 해결하기 위해 창출된 것으로서, 전기자동차의 배터리 트레이에 구비된 휴즈의 교환을 안전하고 빠르게 교환할수 있는 전기자동차의 배터리 트레이를 제공하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the problems as described above, and an object thereof is to provide a battery tray of an electric vehicle that can safely and quickly replace the exchange of a fuse provided in the battery tray of the electric vehicle.
