Battery module including connection terminals arranged in zigzag-shaped manner

The present invention relates to a battery module capable of improving coupling space efficiency, and more particularly, to a battery module comprising one or more battery cells inside a case, and connection terminals arranged at central portions of respective side surfaces of the case, each of the connection terminals includes at least one pair of a positive terminal and a negative terminal. A positive terminal and a negative terminal are connected to a battery cell in a case, both the positive terminal and the negative terminal protrude to the outside, and the positive terminal, a gap between the positive terminal and the negative terminal, and the negative terminal are arranged at the same interval with respect to a center of the case. 本发明涉及一种能够提高联接空间效率的电池模块，并且更具体地说，涉及以下电池模块，该电池模块包括在在壳体内部的一个或更多个电池单元、以及布置在壳体的各个侧表面的中心部分的连接端子，其中，连接端子中的每一个包括至少一对正极端子和负极端子。正极端子和负极端子连接到壳体中的电池单元，正极端子和负极端子二者均突出到外部，并且正极端子、正极端子与负极端子之间的间隙、以及负极端子相对于壳体的中心以相同的间隔布置。
