Abstract

The invention relates to a new energy vehicle battery pack assembly and a new energy vehicle. The battery pack assembly comprises an upper housing, a lower housing and a battery module; the inner sidefaces of the upper and lower housings are provided with symmetric framework structures; battery modules are fixedly arranged in the framework structures of the inner side faces of the upper and lowerhousings. According to the new energy vehicle battery pack assembly and the new energy vehicle, the battery pack assembly is simple and compact in structure, high in safety performance, strong in loading capacity, convenient to the install and dismantle and high in universality, the fastening of the battery modules can be achieved, the requirements of the installation reliability of the battery modules are met to greatly improve the vibration resistance and anti-impacting performance of the battery modules and the battery pack assembly, the overall structure of the battery pack assembly is simple, the processing and the assembling are convenient and easy, the rigid strength is high, the battery pack assembly is easy to process and produce, the barycenter and stability of a vehicle body are not affected, and a light-weight designing concept is thoroughly presented.

Description

technical field [0001] The invention belongs to the technical field of automobile parts, and in particular relates to a new energy vehicle battery pack assembly and a new energy vehicle. Background technique [0002] With the intensification of the energy and environmental crisis, it is particularly important to study an energy-saving and environmentally friendly vehicle that can alleviate energy pressure and reduce environmental pollution. Pure electric vehicles are one of the main development directions of the future automotive industry; electric vehicles are based on power batteries and drive The motor replaces the traditional power source of the car, and the power battery is the core component of the electric car. As the main power source of pure electric vehicles, the power battery must be installed and fixed reliably, which plays a vital role in its safety. [0003] In order to ensure sufficient continuous driving capability, electric vehicles need to install a large ...
