Abstract

The invention relates to the technical field of new energy vehicles and provides a power battery box of an electric vehicle. The power battery box comprises a lower box body and a battery bracket which are made of carbon fibers, wherein the battery bracket comprises u-shaped beams which are distributed in a crossing manner and open downwards, grooves corresponding to openings of the u-shaped beams are formed in the bottom wall of the lower box body and matched with the opening sizes of the u-shaped beams, and the u-shaped beams and the bottom wall of the lower box body are closed to form a closed cavity. The power battery box of the electric vehicle adopts the carbon fibers and corresponding concave structures are arranged on the lower box body and the battery bracket, so that the battery bracket and the lower box body are closed to form a hollow whole cavity structure, the weight of the battery box is reduced while the overall rigidity and strength of the battery box are improved, and light weight of the whole vehicle is realized. Besides, the battery box made of the carbon fibers has the characteristics of insulation, flame retardance and the like, so that the safety of the whole vehicle can be improved. Further, the battery box adopting the whole cavity structure better facilitates assembly and batch production, and the product consistency is improved accordingly.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a power battery box of an electric passenger vehicle. Background technique [0002] Power battery is currently the only source of power energy for electric vehicles, and it is one of the important factors affecting the performance of electric vehicles. The safety of the battery pack directly affects the safety of the vehicle, and the battery box, as the carrier of the battery pack, plays a key role in the safe operation and protection of the battery pack. The design of the battery box needs to fully consider various factors. In electric vehicles, due to the limited space, the battery box should not only contain more batteries, but also perfectly match the vehicle, so the design requirements for the battery box will be higher. [0003] At present, the power battery boxes of electric vehicles at home and abroad are mostly connected by engineering plastics and steel be...
