The invention relates to a battery tray, a power battery pack and a vehicle. The battery tray is provided with an accommodating cabin for accommodating a battery monomer, wherein each battery monomeris provided with a monomer explosion-proof valve, the battery tray comprises a tray main body, a gas channel is formed in the tray main body, the tray main body is provided with a gas inlet hole and agas outlet hole so as to make flame, smoke or gas exhausted from each monomer explosion-proof valve enter the gas channel through the corresponding gas inlet hole, a storage bag is arranged in the gas channel, and a phase change material is arranged in the storage bag. Through the technical scheme, once the internal air pressure of a certain battery monomer is increased, the monomer explosion-proof valve on the battery monomer is opened, and flame, smoke or gas in the battery monomer directly enters the gas channel of the tray main body through the gas inlet hole in the tray main body, so that the flame, smoke or gas cannot enter the battery accommodating space, and secondary damage to the battery or influence on other batteries caused by the flame, smoke or gas is avoided.

    本公开涉及一种电池托盘、动力电池包及车辆,电池托盘设有用于容纳电池单体的容纳舱,每个电池单体具有单体防爆阀,电池托盘包括托盘主体,托盘主体的内部形成有气体通道,托盘主体上设有进气孔和排气孔,使得从每个单体防爆阀排出的火焰、烟雾或气体经由对应的进气孔进入气体通道;气体通道里设有收纳袋,收纳袋里设有相变材料。通过上述技术方案,一旦某一电池单体内部气压增大,致使其上的单体防爆阀开启时,电池单体内部的火焰、烟雾或气体将直接通过托盘主体上的进气孔进入托盘主体的气体通道内,使得该火焰、烟雾或气体不会进入电池容纳空间,从而避免该火焰、烟雾或气体对电池造成二次伤害或者影响其他电池。
