The invention discloses a battery pack pressure relief protection system, a design method thereof and a vehicle, and relates to the technical field of batteries. The battery pack pressure relief protection system comprises a battery pack box body, a fireproof heat insulation wall, a pressure relief flame path and a gas collecting tank. The battery pack box body is used for accommodating a batterymodule, the fireproof heat insulation wall is arranged in the battery pack box body, and the fireproof heat insulation wall divides the interior of the battery pack box body into a plurality of mutually independent isolation areas; one-way pressure release valves are arranged on the battery pack box body at the two ends of all isolation areas, the gas collecting tank is laid above an explosion-proof exhaust port of the battery module, and the two ends of the gas collecting tank are communicated with the one-way pressure release valves respectively; the pressure relief flame path and the one-way pressure relief valves are located at the same end of the battery pack box body, and the one-way pressure relief valves are used for collecting air flows in the gas collecting tank into the pressurerelief flame path. Through the processes of gas collection guide, one-way pressure relief and flame path collection, the flowing direction of high-temperature gas flame can be well controlled, and the safety of the battery pack is improved.
本发明公开了一种电池包泄压防护系统及其设计方法和车辆,涉及电池技术领域。本发明的电池包泄压防护系统包括电池包箱体、防火隔热墙、泄压火道和集气槽;电池包箱体用于容纳电池模组,防火隔热墙设于电池包箱体内部,防火隔热墙将电池包箱体内部分为多个相互独立的隔离区域;在每个隔离区域两端的电池包箱体上均设有单向泄压阀,集气槽铺设于电池模组的防爆排气口上方,集气槽的两端分别与单向泄压阀连通;泄压火道与单向泄压阀处于电池包箱体的同一端,单向泄压阀用于将集气槽中的气流汇集到泄压火道内。本发明经过集气引导、单向泄压、火道汇集的过程,可以很好地控制高温气焰的流动方向,提高了电池包的安全性。
