Investigation To Parametric Matching And Experimental Technique For Fuel Cell Electric Vehicles

Since 2000, The Ministry of Science and Technology of the People's Republic of China has launched the Clean Vehicle Action Plan and High Technology Development Program (863) major scientific and projects on Special Electric Vehicles, has greatly promoted China's automakers independent research and development of new energy vehicles, while further industry turned into preparations for the new energy Automotive Technology to develop standards and regulations put forward new demands. For this reason, the study of fuel cell vehicle propulsion performance, fuel economy, reliability and test methods is of very practical significance.In this thesis, brief background and fundamentals of fuel cell vehicles, fuel cell vehicle characteristics and types of fuel cell vehicles are introduced, including national and international standards and related conditions.According to relevant technical materials approaches for deter-mination of fuel cell vehicle performance indeces to make a fuel cell vehicle powertrain selection. In the theoretical calculations and engineering analysis, key parameters of the fuel cell, lithium-ion batteries, motors and drive train components are studed for a system match, in the case that the power capability and fuel economy can match the technical requirements.Various components of powertrain operating principle and characteristics are investigated by use of simulation software ADVISOR. In comparison of simulation results under different conditions with real vehicle test results, it is indicated that the model can reflect the performance characteristics of fuel cell vehicles, and the vehicle's power and economy can meet pre-defined technical goals.Model tests of fuel cell vehicles are performed for writing up evaluation the test standards for the vehicle power performance studying and formulating Fuel Cell Vehicle the Maximum Speed Test Method draft. Further, for fuel economy evaluation testing methods for accurate estimation of the vehicle driving range and the rational ues of limited fuel are of instructive significance. As Fuel Cell Hybrid Electric Vehicle Energy Consumption Measurement Method draft can be provided to be technical support. For reliability analysis and reliability test design, provide key components for fuel cell vehicles a valuable may be easily analyzed reference. This thesis supplices basic efforts for the fuel cell vehicle powertrain selection and parameters determination. The technical foundation is also laid for dynamic performance and fuel consumption tests in the study of fuel cell vehicle development test standards. Therefore, the results of this research on promotion of China's industrialization of fuel cell vehicles to achieve the goal of sustainable development in the automotive industry are obtained. Such a continuous effort made for clean environment and ensuring energy security is of a certain practical significance.
