The invention discloses an automobile lithium battery pack protection device, which comprises a protection shell, wherein a battery pack storage cavity is formed in the protection shell, a heat dissipation opening is formed between the upper wall face of the battery pack storage cavity and the upper end face of the protection shell in a communicating mode, and a charging electromagnetic iron corecavity is formed in the upper wall surface of the battery pack storage cavity on the left side of the heat dissipation opening in a communicating manner. According to the invention, the lithium battery pack of the electric vehicle is subjected to heat dissipation treatment, so that a good discharging environment can be provided for the lithium battery pack; the device can be used for placing the lithium battery pack in a closed mode, so that the battery can be effectively prevented from being affected with damp while gas generated in short-circuit state can be exhausted in time, and explosioncaused by excessive gas in the lithium battery is effectively reduced; and the device can seal the lithium battery pack in time while the safety protection equipment of the lithium battery pack is completely invalid, so that damage to an automobile caused by explosion of the lithium battery pack is reduced, and automobile owner loss is reduced.

    本发明公开的一种汽车锂电池组保护装置,包括防护壳体,所述防护壳体内部设有电池组存放腔,所述电池组存放腔上壁面与所述防护壳体上端面之间连通设有散热口,所述散热口左侧的所述电池组存放腔上壁面连通设有充电电磁铁芯腔,本发明通过对电动汽车锂电池组进行散热处理,能够为锂电池组提供良好的放电环境,同时本装置能够对锂电池组进行封闭放置,能够有效防止电池受潮的同时还能够将短路状态下产生的气体及时排出,有效的降低了锂电池内部因气体过多而爆炸,同时本装置在锂电池组安全防护设备完全失效的同时,能够及时的将锂电池组进行密封,减少锂电池组爆炸而对汽车产生损坏,减轻车主损失。
