Study On Parameters Optimization And Dynamic Performance Simulation Of Extend-Range Electric Vehicle

Development of traditional fuel vehicles change a lot of people’s daily live,it has changed the way people travel and increased the efficiency of people travel.But in serious pollution of the energy shortage today, the development of traditional fuel vehicles is limited to a certain extent, the development of new energy vehicles is the trend.Extended range electric vehicles as a new energy models of new energy vehicles, how its dynamic performance is one of the key point.Before pure electric vehicle technology is not a major breakthrough, to increase electric car program research is necessary. This paper focuses on extended-range electric vehicle dynamic performance analysis and optimization, and compared with traditional fuel vehicles.The main contents are:First, access to information for a definition of their present development of electric vehicles by the program.Derivation of the core components of electric vehicles by the program.parameter calculation formula and design requirements of data into the derivation of the formula used to calculate the range extender(APU), the motor and battery parameters.Extended range electric vehicles for stress analysis, the selected parameters into which the core components of the formula in order to obtaining the dynamic performance of the core component parameters are optimized combination of orthogonal analysis.Calculated and applied Lab VIEW interface design and performance calculation.Calculation traditional fuel vehicles and extended-range electric vehicle dynamic performance and value in terms of the use of economic and compare the use of electric vehicles by the program of economic performance is better than traditional fuel vehicles.Finally, by electric car program as well as traditional fuel vehicles based on NEDC conditions were simulated and analyzed to compare their performance and emission performance power, then calculation and simulation results for comparison, the extended range electric vehicles and fuel vehicle dynamic performance basic the case of equal emissions by electric car program has a significant advantage.
