Problems solved by technology

[0004] Protection devices such as lithium battery outer boxes mainly protect the internal lithium battery pack, and the internal structure and safety of the battery system itself need to be considered. However, the existing lithium battery explosion-proof and anti-collision protection devices are difficult to process and assemble due to their complex structure. High, high cost, not suitable for low-cost lithium battery solutions

Abstract

The invention relates to a lithium battery protection box comprising a box body and a box cover, wherein the box cover is provided with a first connecting flange, the box body is provided with a second connecting flange, the first connecting flange is fixedly connected with the second connecting flange via a bolt and a nut, the a plurality of reinforcing brackets are symmetrically arranged on an inner side of a wall board of the box body, and rubber buffer blocks are arranged on the reinforcing brackets. The lithium battery protection box has the advantages of simple structure, convenient manufacture and assembly, high strength, good shock absorption and anti-collision performance, and capability of protecting a lithium battery pack more effectively.

Description

technical field [0001] The invention relates to the technical field of industrial lithium battery protection, in particular to a lithium battery protective box. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels, the use of new vehicle power devices), integrated vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Automobiles with new technology and new structure. [0003] As a new high-voltage, high-energy-density rechargeable battery, lithium-ion secondary batteries have a wide range of civilian and national defense applications due to their unique physical and electrochemical properties. Its outstanding features are: light weight, large energy storage (high energy density), and long service life. In the case of the same volume and weight, the storage capacity of lithium batteries is 1.6 times that of nickel-...
