Embodiment Construction

[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0049] In the related art, the air filter can only adsorb harmful gases in the air, but cannot desorb them. After the vehicle is used for a long time, the adsorption efficiency of the air filter on harmful gases gradually decreases, resulting in the harmful gases in the air. The battery creates a hazard and shortens the life of the air filter.

[0050] In order to overcome the above problems, the present application proposes an air filter system...

Abstract

The invention provides an air filtering system, a control method and a vehicle. The air filtering system comprises a fuel cell, an air compressor, an air filter, a desorption system and an electronic control unit, the fuel cell is used for providing electric energy, the air compressor is connected with the fuel cell and used for providing filtered air for the fuel cell, the air filter is connected with the air compressor and used for filtering the air, and the desorption system is used for desorbing the air. The desorption system is connected with the air filter and used for desorbing the air filter, and the electronic control unit is connected with the desorption system and used for controlling the desorption system to desorb the air filter. By arranging the desorption system and controlling the desorption system to desorb the air filter under the control of the electronic control unit, harmful gas and dust adsorbed by the air filter are discharged, so that the adsorption efficiency of the air filter is improved; harmful gas is prevented from entering the fuel cell through the air filter and the air compressor to damage the fuel cell.

Description

technical field [0001] The present invention relates to the technical field of vehicles, and in particular, to an air filtration system, a control method and a vehicle. Background technique [0002] Due to the requirements of fuel consumption and environmental protection regulations, new energy vehicles have become the development trend of automobiles, and hydrogen energy vehicles have gradually become the mainstream models in the future. Fuel cell power generation requires air and hydrogen to react, but SO in the air 2 , NO X , NH 3 Gases such as n-butane and n-butane are more harmful to fuel cells, so the air filter of hydrogen energy vehicles should filter the above harmful gases in the air in addition to filtering dust. [0003] In the related art, after the vehicle is used for a long time, the adsorption efficiency of the air filter for harmful gases gradually decreases, which causes the harmful gases in the air to harm the fuel cell and shortens the service life of ...
