일반적으로 전기자동차는 2차전지로 이루어진 배터리를 주동력원으로 사용한다. 이러한 배터리는 차량의 구동부에 전기를 공급할 경우 열이 발생함에 따라 저항도 함께 상승하여 방전이 가속되고 충전효율도 감소되므로, 냉각수단이 마련된 배터리 케이스에 내장된다.Generally, an electric vehicle uses a secondary battery as a main power source. Such a battery is built in a battery case provided with a cooling means, since electric power is supplied to the driving unit of the vehicle, the resistance rises as the heat is generated to accelerate the discharge and reduce the charging efficiency.

통상적인 전기자동차의 배터리 케이스는 공급덕트가 마련되어 전기자동차의 주행시 공급덕트를 통해 냉각공기를 제공하여 안착부에 안착된 배터리를 공냉식으로 냉각시킨다.A battery case of a typical electric vehicle is provided with a supply duct to provide cooling air through a supply duct at the time of running of the electric vehicle, thereby cooling the battery placed in the seat portion by air cooling.

하지만, 이러한 통상의 배터리 케이스는 배터리에 열이 발생함에 따라 배터리의 냉각시 결로에 의한 응축수가 발생하여 케이스의 바닥에 고이게 되는 문제가 있고, 바닥에 고인 담수(응축수)를 외부로 배출할 수 있는 수단이 마련되지 않기 때문에 배터리에 배선된 전선이나 커넥터 또는 PCB기판이 담수에 의해 누전이 발생하여 배터리의 성능에 치명적인 영향을 끼치는 문제점이 있다.However, such a conventional battery case has a problem that condensation water due to condensation is generated at the time of cooling of the battery as heat is generated in the battery, so that the battery is floated on the bottom of the case, and fresh water (condensed water) There is a problem that electric wires or connectors or PCB boards wired to the battery are leaked by the fresh water and the performance of the battery is severely affected.

더불어, 이러한 배터리 케이스는 한번 장착 후, 착탈이 되지 못하게 되어있는 구조를 가진다는 문제와 함께, 이로 인해 내부에 오염물 및 먼지등이 투입될 경우, 이를 제거할 수 있는 방법이 없었으며, 배터리의 전원량이나 전원유무 또한 외부로에서 케이스 자체에서는 확인이 불가하다는 불편함도 있었다.In addition, there is a problem that such a battery case has a structure in which it can not be attached and detached after being mounted once, and there is no way to remove it when pollutants and dust are put into the inside of the battery case, There was also the inconvenience that it was impossible to confirm the presence of power or power in the case itself.
