Abstract

The invention discloses an air compression system of a fuel cell electric vehicle. Air is provided for a fuel cell and an air storage tank of a braking air circuit simultaneously by adopting an air compressor, so that the system is high in integration level and relatively low in cost; and moreover, relative to a conventional air compressor used for braking, the air compressor provided by the invention is in a variable load continue working state for a long time, so that the abrasion of the air compressor is reduced, and the reliability is relatively high.

Description

technical field [0001] The present application relates to the technical field of fuel cell electric vehicles, and more specifically, relates to an air compression system for fuel cell electric vehicles. Background technique [0002] A fuel cell electric vehicle is a vehicle that uses hydrogen and oxygen in the air to generate electricity through an electrochemical reaction in a fuel cell under the action of a catalyst, and is used as the main power source to drive the vehicle. In the existing fuel cell electric vehicle, air is supplied through two independent systems of the fuel cell air circuit air compressor and the brake air circuit air compressor. The air compressor of the brake air circuit works intermittently, and the start-stop mode often occurs. When the air compressor starts, the load impact is large and the wear is relatively large. Contents of the invention [0003] In view of this, the present application proposes an air compression system for a fuel cell elec...
