The opening / closing member 24 not only prevents the upward movement of the positive electrode portion 21 and the negative electrode portion 22 from interfering with each other so as to enable charging of the electric bus B, and also in the situation where charging is not required. By preventing the external exposure of the 21 and the cathode portion 22 it is possible to prevent a safety accident.

이와 같이, 양극단자(11)와 양극부(21) 및 음극단자(12)와 음극부(22) 간의 도킹이 이루어진 후 상기 전기버스(B)가 상기 가이드레일(13)을 따라 이동하면서 충전이 이루어지게 된다. 이처럼, 본 발명에 의하면 기존의 버스정류장을 이용하여 배터리를 충전할 수 있도록 구성됨으로써, 전기버스(B)의 충전을 위한 별도의 충전소가 요구되지 않게 되어 배터를 충전을 위한 공간확보의 어려움을 극복할 수 있게 되고, 전기버스(B)의 운전자가 차량에 탑승한 상태로 배터리의 충전이 가능하게 됨으로써 배터리 충전을 신속하고 편리하게 할 수 있게 되며, 일정구간마다 설치되어 있는 버스정류장을 이용하여 수시로 충전이 가능함으로써 소용량 배터리의 사용이 가능하게 된다.As such, after the docking is performed between the positive electrode terminal 11 and the positive electrode portion 21 and the negative electrode terminal 12 and the negative electrode portion 22, the electric bus B moves along the guide rail 13 while charging is performed. Will be done.
