The invention relates to a battery pack and an electric vehicle. The battery pack comprises the following components of: a plurality of battery cells which are stacked in the thickness direction of the battery cells to form a battery cell group; a box body enclosure frame which is integrally formed and is provided with an opening; a fixing plate matched with the opening; and a bottom plate matched with the box body enclosure frame. The bottom plate is fixed below the box body enclosure frame, the fixing plate is fixed at the opening, and the bottom plate, the fixing plate and the box body enclosure frame form a cavity for accommodating the battery cell group. According to the battery pack, related structural features of a battery module in a traditional battery pack are omitted, battery cells are directly put into the battery pack, and the size of the battery pack is greatly reduced.

    本公开涉及一种电池包及电动汽车,电池包包括:多个电芯,多个所述电芯沿自身厚度方向堆叠形成电芯组;箱体围框,所述箱体围框一体成型,所述箱体围框具有开口;固定板,与所述开口相配合;以及,底板,与所述箱体围框相配合;所述底板固定在所述箱体围框下方,所述固定板固定在所述开口处,所述底板、所述固定板及所述箱体围框组成容纳所述电芯组的腔室。本公开省略了传统电池包中电池模组相关的结构特征,将电芯直接放入电池包中,大大减小了电池包的体积。
