The present invention relates to a manufacturing method of a battery connection busbar for an electric vehicle, and more specifically, to the manufacturing method of the battery connection busbar for the electric vehicle, which easily manufactures the bus bar which electrically connects a plurality of batteries used in the electric vehicle without defects. According to the present invention, the manufacturing method of the battery connection busbar for the electric vehicle, in the manufacturing method of the busbar which electrically connects the battery of the electric vehicle, includes the steps of: a cutting step of punching and cutting a metal plate into a busbar shape with a press; a deburring step of removing a burr formed on an edge portion of the busbar in the cutting step; a masking step of covering and masking a terminal portion formed at both ends of the busbar; a coating step of forming an insulating coating layer on the outer peripheral surface of the busbar with both ends masked; a masking removal step of removing caps covered on both ends of the bus bar; and a coating removal step of further removing a portion of the coating layer adjacent to the cap after removing the cap.

    본 발명은 전기차용 배터리 연결 버스바의 제조방법에 관한 것으로서, 특히 전기차에 사용되는 다수개의 배터리를 전기적으로 연결하는 버스바를 불량없이 용이하게 제조할 수 있는 전기차용 배터리 연결 버스바의 제조방법에 관한 것이다. 본 발명의 전기차용 배터리 연결 버스바의 제조방법은, 전기차의 배터리를 전기적으로 연결하는 버스바의 제조방법에 있어서, 금속판을 프레스로 버스바 형상으로 펀칭하여 절단하는 절단단계와; 상기 절단단계에서 상기 버스바의 모서리 부분에 형성된 버를 제거하는 버제거단계와; 상기 버스바의 양단에 형성된 단자부에 캡을 덮어 마스킹하는 마스킹단계와; 양단이 마스킹된 버스바의 외주면에 절연성의 코팅층을 형성하는 코팅단계와; 상기 버스바의 양단에 씌워진 캡을 제거하는 마스킹제거단계와; 상기 캡 제거 후 상기 캡에 인접한 부분의 코팅층을 일부 더 제거하는 코팅제거단계;를 포함하여 이루어지되, 상기 버제거단계에서는 다이의 라운딩 홈에 상기 버스바의 모서리 부분을 배치한 후 가압하여 버를 제거하는 것을 특징으로 한다.
