【摘要】：为解决当今全球环境污染、石油资源枯竭等问题,低碳、环保已经成为我国能源发展的主旋律。相对于传统的以汽油为动力的汽车,电动汽车具有显著的低碳环保作用,它是全部或部分由电能驱动电机作为动力的汽车。因为它以电代油,不仅能够实现零排放,噪音低,而且是解决交通拥堵、能源短缺和环境污染问题的重要途经之一,而电动汽车充电桩是为电动汽车车载蓄电池提供续航的电能。研究和改进电动汽车充电桩的相关技术问题,既可以为充电桩充电控制系统的设计和建设提供一定的科学理论与实践应用支持,也对促进电动汽车充电桩的产业快速发展及提高电动汽车用户的生活水平具有重要意义。电动汽车及充电桩的相关技术取得了很大进步,但距全面推广应用仍然存在很多问题亟待去克服和解决。调查分析发现,充电桩的技术瓶颈主要在于充电效率不高和计费控制系统的智能化水平低。由于当前市场上电动汽车充电桩的计费控制系统,既存在充电时间长、充电数据易产生丢失、充电标准混乱的问题,还存在充电计费信息向用户告知功能还不够完善等智能化水平不够高的问题,而这些问题对电动汽车充电桩的推广和使用产生了一定的阻碍。本论文采用ARM微控制器进行充电桩计费控制系统的设计,完善了充电计费信息向用户告知和掉电存储的功能,对于提高充电桩计费控制系统的智能化水平具有实际意义。另外,本充电桩计费控制系统的一个重要创新点是采用IC卡进行识别认证充电桩用户,保证了电动汽车用户的信息和财产安全。本论文首先对电动汽车直流充电桩计费控制系统的功能结构、工作原理进行了分析,对主要应用技术、通信方式等进行了介绍;接着,对以STM32F107为核心的ARM微控制器在充电桩计费控制系统中的应用进行了需求分析,进而提出了ARM微控制器在直流充电桩计费控制系统中的应用方案;设计了基于ARM微控制器控制的直流充电桩计费控制系统,设计中增加了GPRS短信发送和掉电存储功能。最后,通过MATLAB仿真软件对系统的模拟开关量控制、模拟输入电压采集等进行验证后,说明可以进一步提高直流充电桩计费控制系统的智能化水平。
[Abstract]:In order to solve the problems of global environmental pollution and oil resource depletion, low carbon and environmental protection have become the main theme of energy development in China. Compared with the traditional gasoline powered vehicle, electric vehicle has a significant low-carbon environmental protection role, it is all or part of the electric drive motor as the power vehicle. Because it uses electricity instead of oil, it can not only achieve zero emissions, low noise, but also is one of the important ways to solve the problems of traffic congestion, energy shortage and environmental pollution. And electric vehicle charging pile is to provide electric energy for electric vehicle car-mounted battery. Researching and improving the related technical problems of charging pile of electric vehicle can provide certain scientific theory and practical application support for the design and construction of charging control system of charging pile. It is also of great significance to promote the rapid development of electric vehicle charging pile industry and improve the living standard of electric vehicle users. Great progress has been made in the related technologies of electric vehicles and charging piles, but there are still many problems to be overcome and solved. Through investigation and analysis, it is found that the technical bottleneck of charging pile is low charging efficiency and low intelligent level of charging control system. Because of the charging control system of electric vehicle charging pile in the current market, the charging time is long, the charging data is easy to be lost, and the charging standard is confused. There are still some problems such as charging information informing users that the function is not perfect and the intelligence level is not high enough. These problems have hindered the popularization and use of electric vehicle charging piles. In this paper, ARM microcontroller is used to design charging pile charging control system, which improves the function of charging information informing users and storing power down. It is of practical significance to improve the intelligent level of charging pile charging control system. In addition, an important innovation of the charging pile charging control system is to use IC card to identify and authenticate charging pile users, which ensures the information and property safety of electric vehicle users. In this paper, the function structure and working principle of DC charging pile charging control system for electric vehicle are analyzed, and the main application technology, communication mode and so on are introduced. The application of ARM microcontroller based on STM32F107 in charging pile charging control system is analyzed, and the application scheme of ARM microcontroller in DC charging pile charging control system is put forward. The charging control system of DC charging pile based on ARM microcontroller is designed. The functions of GPRS short message sending and power down storage are added in the design. Finally, the simulation software MATLAB is used to verify the analog switching control and analog input voltage acquisition, which shows that the intelligent level of DC charging pile charging control system can be further improved.
