Abstract
(EN)
Disclosed are a battery box and a vehicle. The battery box comprises a box body (1), multiple batteries (2), insulating films (3), and a structural adhesive (4). The insulating film (3) covers outside a shell (21) of the battery (2), and the insulating film (3) is provided with an opening (31) such that a corresponding portion of the shell (21) is exposed out of the insulating film (3). The structural adhesive (4) is arranged between the batteries (2) and the box body (1). The area of the opening (31) is A1; the total area of a surface, corresponding to the opening (31), of the shell (21) is A; the thickness of the structural adhesive (4) is L1 and the volume resistivity thereof is ρ1; and the thickness of the insulating film (3) is L2 and the volume resistivity thereof is ρ2, with the relationship of A1, A, L1, ρ1, L2 and ρ2 satisfying formula (I). The insulating film (3) is provided with the opening (31), part of the structural adhesive (4) adheres the shell (21) of the battery (2) to the box body (1) at the opening (31), and part of the structural adhesive (4) adheres the insulating film (3) to the box body (1) at an outer side of the opening (31), thereby ensuring the bonding strength between the batteries (2) and the box body (1). In addition, since A1, the area of the opening (31) of the insulating film (3) satisfies the above relationship with A, L1, ρ1, L2 and ρ2, the covering area of the insulating film (3) on the battery (2) meets the requirements for insulating strength, thereby effectively ensuring the safety performance of the battery box.

L’invention concerne un boîtier de batteries et un véhicule. Le boîtier de batteries comprend un corps de boîtier (1), plusieurs batteries (2), des pellicules isolantes (3), et un adhésif structurel (4). La pellicule isolante (3) recouvre à l’extérieur une coque (21) de la batterie (2), et la pellicule isolante (3) comporte une ouverture (31) de sorte qu’une partie correspondante de la coque (21) est exposée hors de la pellicule isolante (3). L’adhésif structurel (4) est agencé entre les batteries (2) et le corps de boîtier (1). L’aire de l’ouverture (31) est A1 ; l’aire totale d’une surface, correspondant à l’ouverture (31), de la coque (21) est A ; l’épaisseur de l’adhésif structurel (4) est L1 et sa résistivité volumique est ρ1 ; et l’épaisseur de la pellicule isolante (3) est L2 et sa résistivité volumique est ρ2, la relation de A1, A, L1, ρ1, L2 et ρ2 satisfaisant à la formule (I). La pellicule isolante (3) comporte l’ouverture (31), une partie de l’adhésif structurel (4) colle la coque (21) de la batterie (2) au corps de boîtier (1) au niveau de l’ouverture (31), et une partie de l’adhésif structurel (4) colle la pellicule isolante (3) au corps de boîtier (1) au niveau d’un côté extérieur de l’ouverture (31), assurant ainsi la force de soudage entre les batteries (2) et le corps de boîtier (1). De plus, puisque A1, l’aire de l’ouverture (31) de la pellicule isolante (3) satisfait à la relation ci-dessus avec A, L1, ρ1, L2 et ρ2, l’aire de couverture de la pellicule isolante (3) sur la batterie (2) satisfait aux exigences de force isolante, assurant ainsi efficacement la performance de sécurité du boîtier de batteries.

一种电池箱及车辆,电池箱包括箱体(1)、多个电池(2)、绝缘膜(3)以及结构胶(4)。绝缘膜(3)包覆电池(2)的壳体(21)外部,且绝缘膜(3)设置有开口(31)以使壳体(21)的对应部分露出于绝缘膜(3)。结构胶(4)设置于电池(2)与箱体(1)之间。开口(31)的面积为A 1、与开口(31)对应的壳体(21)表面的总面积为A,结构胶(4)的厚度为L 1、体积电阻率为ρ 1,绝缘膜(3)的厚度为L 2、体积电阻率为ρ 2,且A 1、A、L 1、ρ 1、L 2以及ρ 2之间满足式(I)。由于绝缘膜(3)设置有开口(31),且结构胶(4)的一部分在开口(31)处将电池(2)的壳体(21)粘接于箱体(1)、一部分在开口(31)外侧将绝缘膜(3)粘接于箱体(1),由此保证了电池(2)与箱体(1)之间的粘接强度。同时,由于绝缘膜(3)的开口(31)面积A 1与A、L 1、ρ 1、L 2以及ρ 2之间满足上述关系,从而使得绝缘膜(3)在电池(2)上的包覆面积满足绝缘强度需求,由此有效地保证了电池箱的安全性能。
