The invention relates to a connecting device, a battery module and an electric vehicle. The connecting device is a layered structural member, is used for connecting a first battery cell and a second battery cell in series, and comprises a conductive pole, and a first cover plate, a first insulating layer and a second cover plate which are arranged in a stacked manner; the conductive pole sequentially penetrates through the first cover plate, the first insulating layer and the second cover plate, so that the first end of the conductive pole is positioned on the first cover plate, and the second end of the conductive pole is positioned on the second cover plate; the first end is used for being electrically connected with a positive tab of a first battery cell, and the first cover plate is electrically connected with the conductive pole; the second end is used for being electrically connected with a negative tab of a second battery cell, and the second cover plate is in insulated connection with the conductive pole; the first cover plate is used for being connected with a shell of a first battery cell, and the second cover plate is used for being connected with a shell of a second battery cell. According to the connecting device provided by the technical scheme, the conductive pole is used for realizing electric connection between the positive and negative tabs in the two battery cells, so that the first battery cell and the second battery cell are connected in series.

    本申请涉及一种连接装置、电池模组、以及电动车。连接装置为层状结构件,用于串联第一电芯与第二电芯,连接装置包括:导电极柱,以及层叠设置的第一盖板、第一绝缘层和第二盖板;导电极柱依次贯穿第一盖板、第一绝缘层和第二盖板,使导电极柱的第一端位于第一盖板,导电极柱的第二端位于第二盖板;第一端用于与第一电芯的正极耳电性连接,且第一盖板与导电极柱电性连接;第二端用于与第二电芯的负极耳电性连接,且第二盖板与导电极柱绝缘连接;第一盖板用于与第一电芯的壳体连接,第二盖板用于与第二电芯的壳体连接。上述技术方案所提供的连接装置中,导电极柱用于实现两电芯中正负极耳之间的电连接,实现第一电芯与第二电芯的串联。
