Research On The Layout Of Key Parts Of A Pure Electric Passenger Car And Competing Products

In today 's world,with environmental pollution and the depletion of non-renewable energy sources such as oil,more and more countries are beginning to promote green travel,setting the development of pure electric vehicle technology as a national development strategy,and formulating development strategies and policies to vigorously develop pure electric vehicles.Great efforts have been made in the field of new energy vehicles,especially pure electric passenger car technology,to promote global car electrification.The pure electric passenger car is different from the traditional fuel car.It needs a large change in design in principle and structure,and it needs a reasonable arrangement of high-voltage key components to meet the performance requirements of the vehicle.At home and abroad,very significant results have been achieved in the research and development of high-voltage key components and layout of high-voltage key components for pure electric passenger vehicles,forming a complete set of R & D system.At present,pure electric passenger vehicles mainly come from two platforms,one is based on traditional fuel models,and the other is a new pure electric vehicle platform.Regardless of which platform is developed for pure electric passenger vehicles,all There are major differences in the layout of key components from traditional fuel models.This article takes the layout of key components of a pure electric passenger car as the main research object,and conducts research on the layout of key components of pure electric passenger cars with its competing models Emgrand EV and BYD E5.The layout of parts is modeled and the results are analyzed,so as to optimize the layout of key parts and the layout of a pure electric passenger car.First,the structure and principle of key components of pure electric passenger cars are analyzed,and the key components are divided into four modules: power battery,power assembly,electronic control system,and charging and distribution system.The layout of the study provides bedding.Secondly,the analysis and research on the layout of the pure electric passenger vehicle,front cabin and key components,including the difference between the layout of the pure electric passenger car and the traditional fuel vehicle,the analysis and research on the common layout of common vehicles and the key zero The principles and requirements that should be paid attention to during the layout of components.Then carry out analysis and research based on the layout plan ofkey parts of pure electric passenger car for a pure electric passenger car and its competing models Emgrand EV and BYD E5,and determine the current key parts of pure electric passenger car Layout plan.Finally,A2Mac1 competing product analysis software is used to model and analyze the layout of key components of competing car models,thereby optimizing the layout plan of key components of a pure electric passenger car,while accumulating experience and optimizing the layout plan for the follow-up The project development model provides reference basis.The analysis results show that the key components of a pure electric passenger car adopt the "all-in-one" integrated layout method in this article,which can reduce the number of key components and related system components and simplify the complexity of the key component system To effectively optimize the layout of key components of a pure electric passenger car.
