Title:
電気車両用の耐炎防爆電池パック及びその製造方法
Document Type and Number:
Japanese Patent JP7379556
Kind Code:
B2
Abstract:
The present invention discloses a flame-retardant and explosion-proof battery pack for an electric vehicle and a manufacturing method thereof, the battery pack comprising: at least one battery brick consisting of a plurality of batteries, which are electrically connected to define a positive electrode welding sheet and a negative electrode welding sheet; a battery brick positive electrode conducting wire and a battery brick negative electrode conducting wire, which are electrically connected to the positive electrode welding sheet and the negative electrode welding sheet, respectively; and a battery brick cover and a battery brick container, which define a first storage space that is sufficient to accommodate the plurality of electrically-connected batteries, wherein the first storage space is filled with a flame-retardant oil so that the plurality of electrically-connected batteries are immersed in the flame-retardant oil, and the positive electrode conducting wire and the battery brick negative electrode conducting wire are exposed outside the first storage space to form a battery brick assembly. The implementations according to the present invention can overcome the existing defects of electric vehicle battery packs that tend to burn and explode easily.
