a battery box

Abstract

The invention discloses a battery box, comprising an outer box body and a box cover; the outer box body includes a bottom plate, and four side walls extending upward from around the bottom plate and distributed in parallel; the inner wall and the outer wall of each side wall are respectively arranged There are several support strips and heat dissipation strips distributed along the vertical direction, the support strips and heat dissipation strips located on the same side wall are symmetrically distributed on both sides of the same side wall, and the supports on the two side walls distributed in parallel The strips and heat dissipation strips are symmetrically distributed; the space for inserting into the side of the insulating partition is maintained between the adjacent support strips on each side wall, and the two sides of the insulating partition are respectively inserted into the parallel In the symmetrically distributed insertion spaces on the two distributed side walls, the hollow cavity of the outer box is divided into several storage cavities capable of accommodating several battery packs through the insertion of insulating partitions. Beneficial effects: the effective and flexible partitioning of the inner cavity of the battery box is realized, the displacement of the single battery due to vibration is reduced, and efficient heat dissipation is provided.

Description

technical field [0001] The invention relates to a box body, in particular to a battery box, which belongs to the technical field of electric cabinets. Background technique [0002] With the continuous progress of the times, human beings have higher and higher requirements for environmental quality, and green environmental protection has become a major theme of environmental protection. Among them, expanding the use of electric vehicles and reducing the use of fuel-efficient vehicles is the practice of green environmental protection. Specific measures on a theme. [0003] The battery box is an important part of the electric vehicle, and the structural design of the battery box is directly related to the safe working condition of the battery pack in the box. A traditional battery box generally only includes a box body and a box cover fastened on the box body. The box body includes a bottom plate and side plates, and the inner cavity of the box is used to accommodate battery p...

AI Technical Summary

Problems solved by technology

[0004] However, there are defects in the structure of the traditional battery box: the working environment of the battery pack is harsh, mud, water, changes in external temperature difference, and vibration of the vehicle body are likely to affect the working characteristics of the battery and the safety of the battery. Often, when the vehicle is running, the battery is prone to displacement due to vibration, which leads to the short circuit between the single batteries, which may eventually cause accidents such as the explosion of the battery box; at the same time, the temperature of the single battery during the operation of the electric vehicle It will continue to rise, and the power battery is sensitive to temperature. If the heat in the battery box during the operation of the electric vehicle is not effectively dissipated, it will directly affect the performance and service life of the battery
