Lithium battery pack dust collection device for new energy vehicle

Abstract

The invention discloses a lithium battery pack dust collection device for a new energy vehicle. The device comprises a lithium battery pack and an electrostatic dust collector, wherein a damping spring is arranged at the bottom inside the lithium battery pack, and a placing plate is arranged at the top of the damping spring; the electrostatic dust collector is connected with the side face of the lithium battery pack in a running through manner; a ventilator is connected with one end of the electrostatic dust collector and is positioned on one side of the lithium battery pack in a running through manner; and a filter screen is arranged inside the other end of the electrostatic dust collector. In the device, the electrostatic dust collector has energy consumption less than that of other dustcollectors, airflow pressure loss is generally 10-50 millimeters of water, and the dust collection efficiency is 90-99.9 percent. The device is suitable for removing dust having a size of 0.05-50microns, can be used in high-temperature high-pressure situations, can be continuously operated, and can be used for sufficiently cooling a lithium battery by matching with the ventilator to avoid damaging the lithium battery caused by high-temperature overheating.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a lithium battery box dust removal device for new energy vehicles. Background technique [0002] New energy vehicles refer to all other energy vehicles except gasoline and diesel engines, including fuel cell vehicles, hybrid vehicles, hydrogen energy vehicles and solar vehicles, etc., and their exhaust emissions are relatively low. According to incomplete statistics, the world's existing There are more than 4 million liquefied petroleum gas vehicles and more than 1 million natural gas vehicles. At present, most of the new energy vehicles on the Chinese market are hybrid vehicles and pure electric vehicles. According to the definition announced by the National Development and Reform Commission of the People's Republic of China, the new Energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels, the use of...

AI Technical Summary

Problems solved by technology

[0003] Most new energy vehicles are driven by lithium batteries, and lithium batteries will generate a lot of heat when they are working, and a lot of dust will adhere to the surface of lithium batteries due to static electricity. These dusts will seriously affect the heat dissipation of lithium batteries and affect the normal operation of lithium batteries. Therefore, a dust removal device for lithium battery boxes for new energy vehicles is needed
