Abstract

The invention discloses fuel cell compressor test equipment, a test method, a coolant flow rate determination method and application, and belongs to the field of new energy automobiles. The fuel cellcompressor test equipment is characterized by comprising an air inlet system, an air compressor, an exhaust system and a cooling system. The air inlet system comprises an air inlet pipeline II, a hotfilm flowmeter I, an air inlet pipeline I, an air filter and an air inlet air conditioner. One end of the air inlet pipeline II is connected with an air inlet of the air compressor, and the other endof the air inlet pipeline II is connected with one end of the hot film flowmeter I. The other end of the hot film flowmeter I is connected with one end of the air inlet pipeline I. The other end of the air inlet pipeline I is connected with one end of the air filter, and the other end of the air filter is connected with the air inlet air conditioner. The hot film flowmeter I is used for detectingand recording the air flow. The invention aims to provide the fuel cell compressor test equipment, the test method, the coolant flow rate determination method and the application, so as to test the performance of the air compressor in the new energy automobiles.

Description

Technical field [0001] The present invention relates to the field of a new energy automobile air compressor, and more specifically, to a fuel cell compressor test equipment, a test method, a cooling liquid flow rate determination method, and application. Background technique [0002] In the fuel cell system, the air compressor is an extremely important part of the system. It is a device that converts the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy, and is a pressure generating device for compressed air. With the continuous development of fuel cells, the performance and control of air compressors greatly affect the stability and use efficiency of fuel cells. Therefore, the detection of air compressor performance is becoming more important and urgent. [0003] And as the performance of air compressors continues to develop, it is necessary to conduct complete and detailed inspections of air compressors ( The air compressor used in the air...
