A battery device with a hierarchical structure

Abstract

The invention provides a battery device with a hierarchical structure, including a battery and a battery box for accommodating the battery; the battery box includes side walls respectively arranged on both sides of the battery box and a battery box arranged at the bottom of the battery box. The upper and lower bottom plates; the side wall and the upper and lower bottom plates enclose a battery installation position for accommodating the battery; the side wall includes a first panel arranged on the inner side and a second panel arranged on the outer side; the side surface of the first panel facing the battery installation position is specifically It is a carbon fiber board, and its plane is perpendicular to the upper and lower bottom plates; the side of the first panel facing away from the battery installation position is specifically a carbon fiber board, and is specifically an outwardly curved arc surface; the second panel faces and backs The two sides of the battery installation position are carbon fiber boards, and they are all outward arc surfaces; the interiors of the first panel and the second panel are filled with nanofiber fillers; the application of this technical solution can make the battery device face It can absorb energy efficiently when impacted.

Description

technical field [0001] The invention relates to the field of automobile safety, in particular to a battery device with a hierarchical structure. Background technique [0002] With the rapid development of electric vehicles in recent years, more and more electric vehicles have emerged and become a new and convenient means of transportation for people. However, in the complex traffic environment, traffic accidents will inevitably occur, which will give people While threatening life safety, it also brings different degrees of property loss. Compared with fuel vehicles, electric vehicles not only need to consider the protection of occupants in collisions, but also battery safety issues unique to electric vehicles. However, the traditional battery box is mainly made of sheet metal stamping, which has a simple structure and lacks the necessary frame structures such as energy absorption and buffering. When an accident occurs, the traditional battery box can not play a good role i...

However, the traditional battery box is mainly made of sheet metal stamping, which has a simple structure and lacks the necessary frame structures such as energy absorption and buffering

When an accident occurs, the traditional battery box can not play a good role in absorbing and protecting the battery, especially when the vehicle is in a high-speed state, causing the battery to withstand a large amount of impact energy, causing short-circuit explosion and other hazards, posing a serious threat to the safety of passengers
