The present disclosure relates to a battery module comprising: a plurality of battery cells each including an electrode tab; and a bus bar connected to the electrode tab to electrically connect the plurality of battery cells to each other. The bus bar includes a plate having a plurality of holes. The electrode tab of each of the battery cells is inserted into at least a part of the plurality of holes of the plate. The electrode tab inserted into the holes and the plate are coupled to each other by a welding bead, and the welding bead has a width and a height defined by equation 1 and equation 2, respectively. La présente invention concerne un module de batterie comprenant : une pluralité d'éléments de batterie comprenant chacun une languette d'électrode ; et une barre omnibus reliée à la languette d'électrode pour relier électriquement la pluralité d'éléments de batterie entre eux. La barre omnibus comprend une plaque présentant une pluralité de trous. La languette d'électrode de chacun des éléments de batterie est insérée dans au moins une partie de la pluralité de trous de la plaque. La languette d'électrode insérée dans les trous et la plaque sont couplées entre elles par un cordon de soudure, et la largeur et la hauteur du cordon de soudure sont définies par l'équation 1 et l'équation 2, respectivement. 본 개시는, 각각이 전극 탭을 포함하는 복수개의 전지 셀, 상기 복수개의 전지 셀을 서로 전기적으로 연결하도록 상기 전극 탭에 연결되는 버스바를 포함하며, 상기 버스바는 복수개의 홀이 형성되는 플레이트를 포함하고, 각각의 상기 전지 셀의 전극 탭은 상기 플레이트의 복수개의 홀 중 적어도 일부에 삽입되고, 상기 홀에 삽입된 전극 탭과 플레이트는 용접 비드에 의해 서로 결합되며, 용접 비드가 식 1 및 식 2에 의해 각각 정의되는 폭과 높이를 가지는 배터리 모듈에 관한 것이다.
