The invention discloses an electric vehicle battery pack structure which comprises a battery module and a lower shell, and a longitudinal beam is arranged in the lower shell in the central axis direction of the lower shell so as to divide the inner space of the lower shell into two symmetrical containing cavities used for containing the battery module; the longitudinal beam is provided with a first installation part used for being longitudinally and fixedly connected with the middle of an automobile body. The left side of the lower shell is provided with a second installation part used for being fixedly connected with a left longitudinal beam of the automobile, and the right side of the lower shell is provided with a third installation part used for being fixedly connected with a right longitudinal beam of the automobile. According to the electric vehicle battery pack structure, the problems that in the prior art, due to the fact that a battery pack center installation point is transversely arranged, the design difficulty is increased, the space in a battery pack cannot be utilized to the maximum degree, and the expansibility of a battery pack platform is extremely poor can be solved.

    本发明公开了一种电动汽车电池包结构,包括电池模组和下壳体,所述下壳体内沿其中轴线方向设有一纵梁,以将所述下壳体内部空间分割为两个对称的用于容置所述电池模组的容置腔;所述纵梁上设有用于与汽车车身中部纵向固定连接的第一安装部;所述下壳体的左侧设有用于与汽车左纵梁固定连接的第二安装部,所述下壳体的右侧设有用于与汽车右纵梁固定连接的第三安装部。本发明所述的电动汽车电池包结构,其可解决现有技术中电池包中央安装点采用横向布置,以致设计难度加大、电池包内空间无法实现最大化利用,且电池包平台扩展性极差的问题。
