Title
(EN) Battery tray, power battery pack and vehicle
(ZH) 电池托盘、动力电池包及车辆
Abstract
(EN)
The invention relates to a battery tray, a power battery pack and a vehicle, the battery tray comprises a tray body, the tray body comprises a bottom plate and side beams, the side beams are arrangedaround the bottom plate, and the side beams and the bottom plate jointly define an accommodating space of a battery monomer; and a gas channel is formed in the bottom plate, a plurality of gas inlet holes and at least one gas exhaust hole are formed in the bottom plate, the gas inlet holes are used for guiding flame, smoke or gas exhausted by the single batteries into the gas channel, and the gasexhaust hole is used for exhausting flame, smoke or gas in the gas channel. Through the above technical scheme, the above technical scheme is adopted, and once the internal air pressure of a certain battery monomer is increased, the single explosion-proof valve on the explosion-proof valve core is opened; and when the battery is charged, smoke or gas in the battery monomer directly enters the gaschannel of the tray body through the gas inlet hole in the tray body, so that the flame, smoke or gas cannot enter the battery accommodating space, and secondary damage to the battery or influence onother 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,所述电池托盘包括托盘本体,托盘本体包括底板和边梁,边梁设置在底板的四周并与底板共同限定出电池单体的容纳空间;底板内部形成有气体通道,底板上设置有若干进气孔和至少一个排气孔,进气孔用于将电池单体排出的火焰、烟雾或气体导入气体通道,排气孔用于将气体通道内的火焰、烟雾或气体排出。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,电池单体内部的烟雾或气体将直接通过托盘本体上的进气孔进入托盘本体的气体通道内,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。
