Explosion-proof and flame-proof battery pack for new energy automobile

Abstract

The invention relates to the technical field of new energy automobile batteries, and discloses an explosion-proof and flame-proof battery pack for a new energy automobile. The explosion-proof and flame-proof battery pack comprises a shell and a battery panel group, an air inlet pipe is welded to the right end of the shell, and an air outlet pipe is welded to the left end of the shell; a driving motor is mounted on the inner wall of the left side of the shell through screws, and the output end of the driving motor is rotationally connected with a first rotating shaft through a bevel gear. The device is simple in structure and novel in design, the heat dissipation of a new energy battery is facilitated, and the temperature of the battery in use is reduced; a positive electrode and a negative electrode of the battery panel group are conveniently fixed, the positive electrode and the negative electrode of the battery panel group are prevented from loosening in the running process of the automobile, and dust is prevented from being accumulated at the positive electrode and the negative electrode of the battery panel group to influence electric conduction; a power supply is conveniently cut off, and the positive electrode and the negative electrode of the battery panel group are disconnected, so that protection is performed, the oxygen content in the shell is reduced, the combustion condition is blocked, and the explosion-proof and flame-proof battery pack is suitable for wide popularization.

Description

technical field [0001] The invention relates to the technical field of new energy vehicle batteries, in particular to an explosion-proof and flame-proof battery pack used in new energy vehicles. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels and new vehicle power devices), and the comprehensive vehicle power control and advanced technology in driving, the formation of advanced technical principles, with With the popularization of new energy vehicles and new technology and new structures, the safety of new energy vehicle batteries has been paid more and more attention by people. [0003] When the existing new energy vehicle battery is in use, it is not easy to dissipate heat, and it is easy to increase the temperature of the battery pack, which has potential safety hazards. When the existing battery pack is connected by wires, the use of conductive clips is easy to m...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an explosion-proof and flame-proof battery pack for new energy vehicles, which can dissipate heat from the new energy battery, reduce the temperature of the battery during use, and facilitate the fixing of the positive electrode and the Negative electrode, to prevent the positive and negative electrodes of the battery plate group from loosening during driving, to avoid the accumulation of dust on the positive and negative electrodes of the battery plate group, which will affect the conduction, and it is convenient to cut off the power supply, so that the positive and negative electrodes of the battery plate group are disconnected, so as to protect and reduce Oxygen content inside the shell, the advantage of blocking combustion conditions, solves the problem of inconvenient heat dissipation, potential safety hazards, and the use of conductive clips when the existing battery pack is connected by wires, which tends to accumulate dust around the positive and negative electrodes of the battery pack , the battery pack cannot be sealed to block the problem of burning conditions
