The invention discloses an electric vehicle storage battery protection device which comprises a protection device body, a protection cavity is formed in the protection device body, and an elastic lifting plate with certain elasticity is fixedly arranged on the lower wall in the protection cavity. According to the invention, by means of a damping device in array, when a device shell is collided, impact force borne by a storage battery pack in the collision process is reduced through multi-point shock absorption, the integrity of the storage battery pack is protected, and an output power supplyof the storage battery pack is cut off while the device is impacted; and when the protection device is damaged by a large impact force, the combustion possibility of a crushing impact part is reducedat the first time through carbon dioxide stored in the protection device, and carbon dioxide gas stored in the protection device is exhausted to form a fireproof protection wall around the storage battery through triggering impact, so that the integrity of the storage battery pack is further protected.

    本发明公开的一种电动车蓄电池保护装置,包括保护装置主体,所述保护装置主体内设有防护腔,所述防护腔内下壁固定设有具有一定弹性的弹性托举板,本发明通过阵列的减震装置在装置外壳受到撞击时,通过多点的减震降低在碰撞过程中蓄电池组受到的撞击力,保护了蓄电池组的完好性,并在装置受到撞击的同时将蓄电池组的输出电源进行切断,并在保护装置因较大冲击力破坏时通过内部存储的二氧化碳在第一时间减少破碎撞击处的燃烧可能性,并通过触发撞击将装置内部存储的二氧化碳气体排出对在蓄电池周围形成防火保护墙,进一步的保护了蓄电池组的完好性。
