New energy battery pack and manufacturing method thereof

Abstract

The invention discloses a new energy battery pack and a manufacturing method thereof. The new energy battery pack comprises an upper shell, a lower shell and a heat dissipation pipe, the heat dissipation pipe is installed in the lower shell, series mold frames are installed at the two sides of the heat dissipation pipe, battery modules are installed in the series mold frames, and prepregs are installed between the battery modules. The manufacturing method of the new energy battery pack comprises the following steps: 1, processing raw materials; 2, injection molding processing; 3, accessory quality inspection; 4, assembling pretreatment; 5, assembling; 6, surface treatment; and 7, circuit detection. The battery module can be protected through the prepregs, the prepregs are soft and flexible, flexible pressure reduction is carried out through elastic deformation when the battery module is pressed, the battery module and internal electrical elements are prevented from being damaged by pressure, the safety of the battery module is ensured, and the service life of the battery module is prolonged.

Description

technical field [0001] The invention relates to the technical field of new energy batteries, in particular to a new energy battery pack and a manufacturing method thereof. Background technique [0002] New energy generally refers to renewable energy that is developed and utilized on the basis of new technologies, including solar energy, biomass energy, water energy, wind energy, geothermal energy, wave energy, ocean current energy, and tidal energy, as well as the energy between the ocean surface and the deep layer. Environmental protection and renewable new energy, such as thermal cycle, are getting more and more attention from various countries, thus promoting the development of new energy batteries. New energy vehicles are developing rapidly under the promotion of national policies. Electric vehicles refer to vehicles powered by on-board power supplies. , a vehicle that drives the wheels with a motor, the battery output as the main power needs to be protected by a battery...

AI Technical Summary

Problems solved by technology

[0003] Existing battery packs are made of metal materials, which not only have a heavy weight, but also the battery pack shell needs to bear the weight of the internal battery module and BMS control system, etc. The weight of the battery pack shell will affect the energy density of the battery pack and the cruising range of the whole vehicle, thereby reducing the performance of the electric vehicle; the existing battery pack lacks a protective structure, so that the battery module inside the battery pack is easily squeezed during the bumping process of the car, thereby shortening the life of the battery module. service life, but also increases the maintenance rate of the battery pack during use, thereby increasing the maintenance cost of the battery pack and reducing the practicability of the battery pack. Therefore, we propose a new energy battery pack and its manufacturing method to solve the above problems
