The invention discloses an explosion-proof and anti-flammable battery charging protection device for an electric vehicle. The anti-explosion and anti-flammable battery charging protection device comprises a charger protection component and a battery protection component; the charger protection component comprises a charger outer box made of a metal compression-resistant material, a charger circuit board is arranged in the charger outer box, an air inlet is formed in one side face of the charger outer box, and an air outlet with an exhaust fan is formed in the other side face, opposite to the air inlet, of the charger outer box. The air inlet and the air outlet are respectively provided with a pressure cover which can close and separate the outside under the impact of the internal air pressure of the charger outer box. The battery protection component comprises a battery storage box made of a metal compression-resistant material, a storage battery and a cooling tank are arranged in the battery storage box, and the cooling tank can automatically open a valve of the cooling tank to release a refrigerant under the impact of internal air pressure of the battery storage box. According to the invention, the problem of disaster loss caused by battery short circuit explosion due to self reasons in the charging process or in the driving and parking process can be solved.

    本发明公开了一种电动车防爆防易燃电池充电保护装置,其包括充电器保护构件和电池保护构件;充电器保护构件包括由金属抗压材料制作而成的充电器外盒,充电器外盒内设有充电器电路板,充电器外盒的一侧面设有进风口,充电器外盒与进风口相对的另一侧面设有自带排风扇的出风口,进风口和出风口上均设有能在充电器外盒的内部气压冲击下关闭隔断外界的压力盖;电池保护构件包括由金属抗压材料制作而成的电池储存箱,电池储存箱内设有蓄电池和冷却灌,冷却灌能在电池储存箱的内部气压冲击下自动打开其阀门释放制冷剂。采用本发明,能解决在充电过程中或在行驶、停放中自身原因引起电池短路爆炸带来的灾害损失问题。
