Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but these embodiments should not be construed as limiting the present invention.

[0014] The hardware structure of the present invention is as figure 1 As shown, includes an air supply controller, GPS / GIS interface, telemetry, flow meter and air compressor. The input end of the air supply controller is connected with the GPS / GIS interface, vehicle speed sensor, remote detector and flow meter, and the output end is connected with the air compressor, and the air flow is adjusted by controlling its speed. The air output from the air compressor enters through the flow meter The fuel cell. The above-mentioned air supply controller obtains information such as the road surface type, average vehicle speed, and average slope of the driving section in real time through the GPS / GIS interface; collects the speed of the vehicle in real time through the mea...

Abstract

The invention relates to a method for controlling an air feeder of an automobile fuel battery. The air feeder comprises an air feeding controller, a global positioning system (GPS) / global information system (GIS) interface, a remote detector, a flow meter and an air compressor, the air feeding controller real-timely acquires information of road surface types, average automobile speeds, average gradient and the like of road sections where an automobile travels through the GPS / GIS interface, an automobile speed sensor measures and real-timely collects speeds of the automobile , the remote detector real-timely collects speeds of a front automobile, expected automobile speed at the next moment of the automobile is obtained by means of weighted average, expected power at the next moment is calculated out according to the expected automobile speeds and the average gradient, accordingly, expected air supply quantity is calculated out, actual air flow is fast identical to expected air flow by means of optimized control, influence of dynamic response time lag of the air compressor is eliminated, oxygen starvation is avoided, prediction control of air supply is achieved, power supply efficiencies of the fuel battery are improved, and service life of the fuel battery is prolonged.

Description

technical field [0001] The invention belongs to a control method for a fuel cell electric vehicle, in particular to a control method for a vehicle fuel cell air supply device. Background technique [0002] A fuel cell is an electrochemical device that uses hydrogen as a fuel and oxygen as an oxidant to directly convert the chemical energy of the fuel into electrical energy. It is not limited by the Carnot cycle. As long as there are enough hydrogen and oxygen, it can be continuously It has the characteristics of high specific energy, low noise, no pollution, zero emission and high energy conversion efficiency. It can be widely used in various fields such as small power stations, communication power supplies, robot power supplies, automobiles, power systems, and family life. Fuel cell technology is considered to be the preferred clean and efficient power generation technology in the 21st century. Fuel cells can be divided into alkaline fuel cells, phosphoric acid fuel cells,...
