The invention provides a power battery crumple protection system and an electric vehicle, and relates to the technical field of electric vehicle protection devices. The power battery crumple protection system comprises a power battery pack body electrically connected with an electric vehicle and anti-collision steel beams which are arranged on the front portion and the rear portion of the power battery pack body respectively. The power battery pack body is fixedly connected with the electric vehicle through a fastening bolt; the power battery pack body comprises a power battery, a power battery cooling system and a protective cover plate, crumple guide grooves are formed in the two sides of the anti-collision steel beams in the vehicle body direction respectively; the fastening bolt can bebroken when the collision energy reaches a preset value, and the anti-collision steel beams drive the power battery pack body to crumple along the crumple guide grooves, so that the crumple space ofthe whole electric vehicle is enlarged, collision energy transmitted to the power battery is reduced, the possibility that the power battery is on fire or even explodes due to extrusion and collisionis reduced, the safety of the electric vehicle is improved, the implementation cost is low, and great production and popularization significance is achieved.

    本发明提供了一种动力电池溃缩保护系统及电动汽车,涉及电动汽车防护装置技术领域,该动力电池溃缩保护系统包括:电连接于电动汽车的动力电池组本体以及分别装设于所述动力电池组本体前后部的防撞钢梁,所述动力电池组本体通过紧固螺栓固定连接所述电动汽车,包括动力电池、动力电池冷却系统和保护盖板,所述防撞钢梁的两侧沿车身方向分别装设有溃缩引导槽,所述紧固螺栓可当碰撞能量达到一预设值时发生断裂,使所述防撞钢梁沿所述溃缩引导槽带动所述动力电池组本体发生溃缩,从而提高整车的溃缩空间,减少传递到动力电池上的碰撞能量,降低了动力电池因挤压碰撞而发生着火甚至是爆炸的可能性,提高了电动汽车的安全性,实施成本较低,具有较大的生产推广意义。
