Abstract
(EN)
The present invention relates to a battery pack and a vehicle. The battery pack comprises: a first battery module, a second battery module, a container, and a fire-resistant member. The first battery module comprises a plurality of battery units, and the battery units each are provided with an explosion-proof valve. The second battery module comprises a plurality of battery units, and the battery units each are provided with an explosion proof valve. The first battery module and the second battery module are disposed within the container. The fire-resistant member is vertically disposed, and the explosion-proof valves of the first battery module and the second battery module face the fire-resistant member disposed therebetween. The above technical solution is different from existing techniques in that the fire-resistant member is used to separate the battery units of the first battery module and the second battery module, thereby preventing thermal runaway of individual or collective battery units, while also reducing the volume and the area of the fire-resistant member by half to reduce costs and improve energy density.

La présente invention porte sur un bloc-batterie et sur un véhicule. Le bloc-batterie comprend : un premier module de batteries, un deuxième module de batteries, un récipient, et un organe ignifugé. Le premier module de batteries comprend une pluralité d’unités de batteries, et les unités de batteries comportent chacune une soupape antidéflagrante. Le deuxième module de batteries comprend une pluralité d’unités de batteries, et les unités de batteries comportent chacune une soupape antidéflagrante. Le premier module de batteries et le deuxième module de batteries sont disposés dans le récipient. L’organe ignifugé est disposé verticalement, et les soupapes antidéflagrantes du premier module de batteries et du deuxième module de batteries font face à l’organe ignifugé disposé entre elles. La solution technique ci-dessus est différente des techniques existantes en ce que l’organe ignifugé sert à séparer les unités de batteries du premier module de batteries et du deuxième module de batteries, empêchant ainsi la fuite thermique d’unités de batteries individuelles ou collectives, tout en réduisant également le volume et l’aire de l’organe ignifugé de moitié pour réduire les coûts et améliorer la densité d’énergie.

本发明涉及一种电池包及车辆。所述电池包包括第一电池模块、第二电池模块、箱体以及防火构件,第一电池模块包括多个电池单体,电池单体设有防爆阀;第二电池模块包括多个电池单体,电池单体设有防爆阀;第一电池模块和第二电池模块均设置在箱体内;防火构件竖直设置,第一电池模块的防爆阀和第二电池模块的防爆阀均面向防火构件,防火构件位于第一电池模块的防爆阀和第二电池模块的防爆阀之间。区别于现有技术,上述技术方案通过防火构件将第一电池模块的电池单体与第二电池模块的电池单体隔开,避免电池单体集体热失控;同时,使防火构件的体积、面积减少一半,降低成本,提高能量密度。
