The Design And Implementation Of Big Electric Car Smart Charging System

With the rapid development of social economy,energy production demand,the traditional oil,coal and other energy of the day will eventually dry up,Chinese as the world's largest country car ownership,exhaust emissions on atmospheric environmental pollution has become increasingly serious,green new energy vehicles will be the future travel choice.In this paper,aiming at the current status of urban green environmental protection traffic management,taking the electric vehicle charging pile as the research background,relying on the charging pile enterprise management platform,a set of intelligent electric vehicle charging system is designed.This article investigates the basic situation of a number of electric car manufacturers in a city,understands the distribution of existing electric vehicle charging piles,finds the basic reason for the current difficulty in charging electric vehicles,after many arguments,and detailed understanding of electric vehicle exchange service exchange information system And business processes to determine the business needs of the study and detailed analysis of various requirements.After in-depth study of software technology research theory,under the guidance of mentors and professional technicians,the EV charging system was designed in detail.The design of the system first determines the system architecture,including the system's physical architecture and deployment structure;secondly focuses on the system.The core business function modules are designed in detail;once again,the interface parameters involved in the system are configured;finally,the system's data transmission system and system security design content are discussed in detail.After the system is implemented,the test environment,configuration parameters and joint debugging with the third-party interface are used to perform detailed tests on the functional modules implemented in the system.The professional test methods and manual tests are used in the test to achieve the test results.Expected design requirements.In the part of system realization,this paper establishes the queuing model and uses the algorithm to compare the charging efficiency of the charging pile under the traditional model and the smart model.The charging status of a month's electric vehicle in a city charging station is used as the data source.The simulation software isused to simulate the example.The model calculation data shows that the electric vehicle has higher charging efficiency and can save queuing time in the intelligent system mode.
