Abstract
(EN)
The present application relates to a battery module, a battery pack, and a vehicle. The battery module comprises a plurality of battery units and a fire-preventing structure, anti-explosion valves being provided on the battery units. The anti-explosion valves of the plurality of battery units all face towards the fire-preventing structure. The fire-preventing structure comprises a fire-preventing structure body and a first extension part connected to one end of the fire-preventing structure body, and/or the fire-preventing structure comprises a fire-preventing structure body and a second extension part connected to the other end of the fire-preventing structure body. In the present invention, by means of the fire-preventing structure, when thermal runaway occurs in a battery unit, flames and high-temperature particles expelled from the anti-explosion valve are stopped by the fire-preventing structure body and the first extension part and/or the second extension part, preventing the flames and the high-temperature particles from burning adjacent battery units, thus preventing the battery unit in which thermal runaway has occurred from causing thermal runaway to also occur in battery units adjacent to the anti-explosion valve thereof.

La présente invention concerne un module de batterie, un bloc-batterie et un véhicule. Le module de batterie comprend une pluralité d'unités de batterie et une structure de prévention contre l'incendie, des soupapes anti-explosion étant disposées sur les unités de batterie. Les soupapes anti-explosion de la pluralité d'unités de batterie font toutes face à la structure de prévention contre l'incendie. La structure de prévention contre l'incendie comprend un corps de structure de prévention contre l'incendie et une première partie d'extension reliée à une extrémité du corps de structure de prévention contre l'incendie, et/ou la structure de prévention contre l'incendie comprend un corps de structure de prévention contre l'incendie et une seconde partie d'extension reliée à l'autre extrémité du corps de structure de prévention contre l'incendie. Dans la présente invention, au moyen de la structure de prévention contre l'incendie, lorsqu'un emballement thermique se produit dans une unité de batterie, des flammes et des particules à haute température expulsées de la soupape anti-explosion sont arrêtées par le corps de structure de prévention contre l'incendie et par la première et/ou la seconde partie d'extension, empêchant les flammes et les particules à haute température de brûler des unités de batterie adjacentes, empêchant ainsi l'unité de batterie dans laquelle un emballement thermique s'est produit de provoquer également un emballement thermique dans des unités de batterie adjacentes à la valve anti-explosion correspondante.

本申请涉及一种电池模块、电池包及车辆。所述电池模块包括多个电池单体以及防火构件,所述电池单体设置有防爆阀;所述多个电池单体的所述防爆阀均面向所述防火构件,所述防火构件包括防火构件主体以及连接于所述防火构件主体一端的第一延伸部;和/或,所述防火构件包括防火构件主体以及连接于所述防火构件另一端的第二延伸部。本申请通过防火构件,当电池单体发生热失控时,电池单体的防爆阀喷出的火焰与高温颗粒被防火构件主体以及第一延伸部和/或第二延伸部挡下,防止喷出的火焰与高温颗粒烧毁相邻电池单体,避免已发生热失控的电池单体引发与其防爆阀相对的邻近电池单体也发生热失控。
