Title
(EN) BATTERY BOX
(FR) BAC DE BATTERIE

Abstract
(EN)
The present application relates to a battery box, comprising: an upper cover (1) comprising a main component and an explosion-proof exhaust structure (3), wherein the main component comprises a top plate (11) at an upper portion and a side plate (12) at a side surface and has an opening at a lower portion, the explosion-proof exhaust structure (3) is disposed at the side plate (12), and an exhaust passage is provided between the top plate (11) and the explosion-proof exhaust structure (3); and a lower box (2), wherein the upper cover (1) covers an upper portion of the lower box (2), and batteries (5) are arranged in the lower box (2) and are each provided with an explosion-proof valve (51). The explosion-proof exhaust structure (3) of the upper cover (1) of the battery box is disposed at the side plate (12), and is employed to discharge sharply increased heat caused by thermal runaway of the battery box from the side surface, thereby effectively reducing potential safety hazards posed by hot air emissions entering a vehicle passenger compartment from the top of the battery box. In addition, structural improvements of the present battery box can be directly made to existing upper cover structures, such that the invention has the advantages of low improvement costs and good effects.

La présente invention concerne un bac de batterie, comprenant : un couvercle supérieur (1) comprenant un composant principal et une structure d'échappement antidéflagrante (3), le composant principal comprenant une plaque supérieure (11) au niveau d'une partie supérieure et une plaque latérale (12) au niveau d'une surface latérale et a une ouverture au niveau d'une partie inférieure, la structure d'échappement antidéflagrante (3) est disposée au niveau de la plaque latérale (12), et un passage d'échappement est disposé entre la plaque supérieure (11) et la structure d'échappement antidéflagrante (3) ; et un bac inférieur (2), le couvercle supérieur (1) recouvrant une partie supérieure du bac inférieur (2), et des batteries (5) étant disposées dans le bac inférieur (2) et comportant chacune une soupape antidéflagrante (51). La structure d'échappement antidéflagrante (3) du couvercle supérieur (1) du bac de batterie est disposée au niveau de la plaque latérale (12), et est utilisée pour décharger une chaleur fortement augmentée provoquée par un emballement thermique du bac de batterie à partir de la surface latérale, ce qui permet de réduire efficacement les risques de sécurité potentiels posés par les émissions d'air chaud entrant dans un compartiment passager de véhicule à partir de la partie supérieure du bac de batterie. De plus, des améliorations structurales du présent bac de batterie peuvent être directement apportées à des structures de couvercle supérieur existantes, de telle sorte que l'invention présente les avantages de faibles coûts d'amélioration et de bons effets.
