The invention relates to the technical field of power batteries, and concretely relates to a battery pack and an electric vehicle. The battery pack comprises a battery pack shell, a fixing piece, a collision guide piece and a battery module; the battery module, the fixing piece and the collision guide piece are all arranged in the battery pack shell; one end of the collision guide piece is propped against the battery pack shell, the other end of the collision guide piece is propped against the battery module, and the collision guide piece is used for supporting the battery pack shell and the battery module; and one side of the fixing piece is respectively connected with the collision guide piece and the battery module, the other side of the fixing piece is connected with the battery pack shell, the collision guide piece is fixed on the fixing piece, and the collision guide piece disperses the received extrusion force to the fixing piece. The collision guide piece supports the battery pack shell and the battery module, the end face, subjected to extrusion force, of the battery pack shell is prevented from collapsing, parts in the battery pack are prevented from deforming and piercing the battery module due to extrusion force, meanwhile, the collision guide piece transmits the extrusion force borne by the battery module to the whole battery pack, and the extrusion force is resisted through the overall strength.

    本发明涉及动力电池技术领域,具体是一种电池包及电动汽车,所述电池包包括电池包壳体、固定件、导撞件和电池模组;电池模组、固定件和导撞件均设置在电池包壳体的内部;导撞件的一端与电池包壳体相抵接,导撞件的另一端与电池模组相抵接,导撞件用于支撑电池包壳体和电池模组;固定件的一侧分别与导撞件和电池模组连接,固定件的另一侧与电池包壳体连接,导撞件固定在固定件上,导撞件将受到的挤压力分散到固定件上;本发明的导撞件支撑电池包壳体和电池模组,避免电池包壳体受到挤压力的端面发生溃缩,也避免了电池包内的零部件受到挤压力形变刺穿电池模组,同时导撞件将电池模组受到的挤压力传到整个电池包,通过整体的强度来抵抗挤压力。
