The present application discloses an explosion-proof valve for a battery pack (1), the explosion-proof valve (2) being capable of removing moisture in the battery pack (1), the explosion-proof valve (2) being provided with: a water absorbing material (21) configured to be capable of absorbing moisture; the drain valve (22) is configured to be opened when the water amount absorbed by the water absorbing material exceeds a preset threshold value so as to drain water to the outside of the battery pack (1); and the fan (23) is configured to be capable of enhancing the flow of gas in the battery pack (1) towards the water absorption material (21). The fan may be provided as a bladeless fan disposed inside the water absorbent material. The drain valve may be provided as a gravity valve, a density valve, and/or a thickness valve. The explosion-proof valve can further comprise a squeezing device to squeeze out moisture absorbed by the water absorbing material (21). The explosion-proof valve not only can be used for exhausting and relieving pressure, but also can be used for discharging moisture in the battery pack. The invention further relates to a battery pack comprising the anti-explosion valve and a related vehicle.

    本申请公开了一种用于电池包(1)的防爆阀,所述防爆阀(2)能够用于去除电池包(1)中的水分,所述防爆阀(2)设置有:吸水材料(21),其配置成能够吸收水分;排水阀(22),其配置成能够在所述吸水材料所吸的水量超过预定阈值时打开,以将水分排至电池包(1)外部;风扇(23),其配置成能够加强电池包(1)内的气体朝向所述吸水材料(21)的流动。所述风扇可设置成布置在吸水材料内侧的无叶风扇。所述排水阀可设置成重力阀、密度阀和/或厚度阀。防爆阀还可包括挤压装置以挤出所述吸水材料(21)所吸收的水分。所述防爆阀不仅能用于排气泄压,还可用于排出电池包中的水分。本申请还涉及包括该防爆阀的电池包以及相关车辆。
