[0002] The battery is installed in the battery box of the electric vehicle. The battery needs some auxiliary components in order to connect with the external power supply. The auxiliary components are also installed in the battery box, but the shape of the auxiliary components is not regular, which leads to the Partially empty, so some material needs to be filled to protect the battery
However, traditional materials are heavy and easy to wear, which not only easily damages the battery, but also makes the specific capacity of the battery box drop rapidly

[0018] The battery pack 3 and the auxiliary components 4 are both arranged in the box body 2, the box cover 1 covers the opening of the box body 2, the battery pack 3 is electrically connected with the auxiliary components 4 to realize the charging and discharging of the battery pack 3, and the box body 2 includes The front side wall and the rear side wall are oppositely arranged, the battery pack 3 is pressed on the front side wall, the auxiliary component 4 is pressed on the rear side wall, there is a gap between the auxiliary component 4 and the box cover 1, and the gap is filled with buffer Insulation Materials.
[0019] The composition of the buffer insulating material is calculated in parts by mass:
[0041] The average density of the buffer insulating material in this embodiment is 1.08g / cm 3 . In addition, the fluidity of the buffer insulating material is reduced to a certain extent compared with Example 1, and it is not easy to enter the void.

Abstract
The invention discloses a battery box for an electric vehicle. The battery box comprises a box cover, a box body, a battery pack and an auxiliary assembly, wherein a gap is located between the auxiliary assembly and the box cover and filled with a buffer insulation material. The buffer insulation material comprises by mass, 50-60 parts of linear low-density polyethylene with a density of 0.92 to 0.925 g / cm<3>, 20-30 parts of polyethylene glycol with a molecular weight of 800-1000 and 10-30 parts of an additive. According to the invention, the linear low-density polyethylene with low density isused as the main body of the buffer insulation material, so the gap can be filled with low-mass substances as much as possible, the material has a good specific heat coefficient and thermal stability, and temperature rise during the use of batteries can be reduced as much as possible.
Description
【Technical field】 [0001] The invention relates to an electric vehicle battery box, which belongs to the field of materials. 【Background technique】 [0002] The battery is installed in the battery box of the electric vehicle. The battery needs some auxiliary components in order to be connected to the external power supply. The auxiliary components are also installed in the battery box, but the shape of the auxiliary components is not regular, which leads to the inside of the box. It is partially vacant, so it needs to be filled with some material to protect the battery. However, traditional materials are heavy and easy to wear, which not only easily damages the battery, but also causes the specific capacity of the battery box to drop rapidly. [Content of the invention] [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an electric vehicle battery box, which reduces battery damage and reduces the...
