Design And Simulation Of Power System For Pure Electric Logistics Vehicle

In recent years,with the increasing problem of environmental pollution and energy shortage,people have gradually paid attention to the development of new energy electric vehicles.Pure electric vehicles are one of the main development targets in the future.They mainly have low driving noise and no pollution emissions Features.The main evaluation indicators of pure electric vehicles include power performance and economic performance,so they should be taken as the main factors to consider during the development and design of pure electric vehicles.However,due to technical influences such as power batteries,the cruising range of pure electric vehicles has not made significant progress.Therefore,in this case,the reasonable matching of the power system parameters of electric logistics vehicles is particularly important.In this paper,a van transporter on the market is used as a prototype.According to the transportation needs of electric logistics vehicles,with the help of automobile design theory and ant colony genetic optimization algorithm,the parameter matching and optimization design of the power system of pure electric logistics vehicles are completed.The main contents of the study are as follows:Study the current development status of electric vehicles at home and abroad,and analyze the design matching and optimization status of electric vehicle power system parameters;Study and analyze the transportation conditions of logistics vehicles,summarize the characteristics of transportation conditions of logistics vehicles,and analyze the power and economic indicators of pure electric logistics vehicles;The force analysis of pure electric logistics vehicles,combined with the transportation conditions of the logistics vehicles and their power performance and economic performance requirements,carried out preliminary selection and selection of the drive system,transmission system and energy system in the power system of pure electric logistics vehicles.The parameter design matches,confirms the type and rated power of the drive motor,and completes the design of the reducer transmission ratio and the selection of the power battery;By setting up a simulation model of the pure electric logistics vehicle power system in AVL-Cruise simulation software,and setting the corresponding calculation tasks,the maximum speed,climbing performance,acceleration performance,and cruising range of the electric logistics vehicle were simulated;Finally,the ant colony genetic optimization algorithm was used to optimize the power system parameters of the pure electric logistics vehicle,and the optimized data was substituted into the simulation software for simulation.Through the analysis and comparison of the simulation results before and after the optimization,the feasibility of the ant colony genetic optimization algorithm for the parameter optimization of the power system of pure electric logistics vehicles is verified,and a new solution is provided for the parameter optimization of the power system of electric logistics vehicles.
