The invention relates to a battery pack, an automobile and a battery cell mounting method. The battery pack comprises a box body, a cross beam and a battery cell group, the two ends of each cross beam are fixedly connected with the first side wall and the second side wall of the box body correspondingly, and a mounting position is formed between every two adjacent cross beams. The battery cell group comprises a plurality of battery cells, one battery cell group is arranged in each mounting position, the battery cells are fixedly connected with the inner bottom wall of the box body, and the battery cells located at the two ends of the battery cell group abut against the first side wall and the second side wall respectively; glue is poured between the battery cell group and the adjacent cross beam to form a glue layer; the glue layers are formed by pouring glue between the battery cell groups and the adjacent cross beams, so that metal particles remained in the gaps between the battery cells and the cross beams can be fixed in the glue layers; in addition, as the gaps between the battery cells and the cross beams are filled with the glue layers, metal particles and welding slag generated after glue sealing can be prevented from entering the gaps between the battery cells and the cross beams, and the safety performance of the battery pack is further improved.

    本发明涉及一种电池包、汽车及电芯安装方法。该电池包包括箱体、横梁以及电芯组;横梁的两端分别与箱体的第一侧壁以及第二侧壁固定连接,相邻两根横梁之间形成安装位;电芯组包括多个电芯,每一安装位内设置有一组电芯组,电芯与箱体的内底壁固定连接,且位于电芯组两端的电芯分别与第一侧壁以及第二侧壁相抵;电芯组与相邻的横梁之间灌封胶水以形成胶水层;通过在电芯组与相邻的横梁之间灌封胶水形成胶水层,能够将残留在电芯与横梁间隙内的金属颗粒固定于胶水层内;此外,由于胶水层将电芯与横梁之间的间隙填满,能够阻挡封胶后产生的金属颗粒、焊渣进入到电芯与横梁之间的间隙内,进一步提升电池包的安全性能。
