Full-sealing battery box

Abstract

The invention discloses a full-sealing battery box. The full-sealing battery box comprises a box body (4), an upper cover (1), a battery pack (10) and a BMS, wherein a sealing gasket (2) and a sealing strip (3) are arranged between the box body (4) and the upper cover (1). With the technical scheme above, structure form of the box body and the upper cover of the battery box is arranged rationally and reinforced, the sealing strip and the sealing gasket are added for sealing each port of the box body of the battery box, thus, protection grade of the battery box reaches IP67 grade standard, risks of being liable to be watered and affected with damp to cause short circuit of a power source of a battery electric vehicle are overcome, and all-weather safety driving of the battery electric vehicle is realized.

Description

technical field [0001] The invention belongs to the technical field of new energy electric vehicles and relates to the power technology of pure electric vehicles. More specifically, the present invention relates to a fully sealed battery box. Background technique [0002] The power battery box is currently the only source of power energy for pure electric vehicles. As the core component of pure electric vehicles, the safety of the battery box directly affects the safety of the entire vehicle. [0003] The battery box should first be designed and developed to meet the requirements of IP67 protection level for electrical equipment enclosures, so as to ensure that the fully sealed battery box is sealed and waterproof, and the battery pack will not be short-circuited due to water ingress. Therefore, the manufacturing process of the battery box must ensure its sealing and waterproof. [0004] Once any part of the box leaks, avoid the blockage of the cooling air flow, lagging and...

AI Technical Summary

Problems solved by technology

[0004] Once any part of the box leaks, avoid the blockage of the cooling air flow, lagging and causing inconsistent working temperature of the battery module, which will lead to and cause a decrease in the working performance of the battery pack, making the power source of the vehicle unstable

However, the defect of the structure of the prior art is that the protection ability is insufficient, especially no special measures have been taken in the aspect of waterproofing, which cannot meet the requirements of safe use.
