Battery pack for new energy automobile

Abstract

The invention discloses a battery pack for a new energy automobile, the battery pack comprises a bottom cover, an upper cover and battery units, two battery packs are arranged between the bottom cover and the upper cover, the two battery packs are symmetrically arranged along the central axis of the bottom cover, each battery pack is formed by a plurality of battery units which are distributed in a rectangular array, the battery unit comprises a mounting plate fixedly mounted at the top of the bottom cover, the top of the mounting plate is slidably connected with a gas storage box and a limiting plate, the outer wall between the gas storage box and the limiting plate is jointly slidably connected with a protective cover, and a storage battery is mounted in the protective cover; a plurality of transmission connecting rods are hinged between the bottom of the protective cover and the top of the mounting plate, and the gas storage tank is mounted on the outer wall of the impacted surface of the protective cover, so that the two sides of two battery packs can be protected, and damage and extrusion between battery units caused by hard impact are prevented; and meanwhile, the fuses among the battery units are disconnected.

Description

technical field [0001] The invention relates to the technical field of battery packs for new energy vehicles, in particular to a battery pack for new energy vehicles. Background technique [0002] With the development of science and technology, new energy vehicles have gradually entered people's lives. New energy vehicles generally use battery packs to provide power sources for vehicles. The connection of multiple batteries forms a battery pack, including lithium iron phosphate batteries and ternary lithium batteries. . [0003] In the daily use of electric vehicles, in the event of an accident, such as an impact, the battery pack is easily squeezed by external force, causing the battery to form a depression and causing damage to the battery. Most of the existing battery packs are arranged in a matrix. , which leads to the fact that when the external battery is squeezed, the adjacent battery is easily implicated, resulting in different degrees of hard squeezing and damage t...

AI Technical Summary

Problems solved by technology

[0003] In the daily use of electric vehicles, in case of accidents, such as collisions, the battery pack is easily squeezed by external force, causing the battery to form a depression and causing damage to the battery. Since most of the existing battery packs are arranged in a matrix , when the external battery is squeezed, it is very easy to implicate the adjacent battery, causing the battery other than the impact to be hard squeezed and damaged to varying degrees
