基于PLC的电动汽车智能充电站Word文档格式.docx

1、而且覆盖面也已经慢慢变小了，造成了电动汽车很大的一个进步空间。本文中所研究设计的就是电动汽车的充电站。此项研究对推动电动汽车的产业有着非常重大的帮助。本本文中所研究的电动汽车充电站，嗯，借鉴了国内外非常优秀的电动汽车充电站，一些非常成熟的经验和宝贵的经验，我查阅了非常多的相关资料，了解了国内外电动汽车充电站地发展和研究成果，分析了电动汽车充电站的各种优点和缺点。制定了一系列有关电动汽车充电站的一个整体方案，根据电动汽车充电站的主控单元去入手分析，就发现可用可编程控制器，也就是plc的工作原理，去选择电动汽车充电站的硬件，设计出了电动汽车充电站的一个非常完美的控制系统。以及人机交互模块和计费剂量

2、系统模块儿，还有语音模块儿和打印模块儿等等，不仅成功地完成了控制系统软件的设计和触摸屏的软件设计，以及各模块通讯协议的设计等等，尤其是plc程序的设计，这样就可以满足每个地方的数据需要。而且可以持续的去实现和完成电动汽车充电站的设计。与此同时，还利用了射频式非接触的读写方式，去完成了充电站计费系统的一些功能。在自主研发的上位机系统管理软件都可以去实现这样的使用，而且在终端装置可以检测到数据的存储，还有处理和分析，方便管理者去统计和分析。本文中研发的电动汽车充电站具有保护系统，还有处短路保护和漏电保护之外，同时还有紧急按钮可以去嗯，遇到紧急危险情况时停止充电功能，按照这样的设计方案。电动汽车充电

3、站操作非常的简洁，而且提供的电源电压在220V左右。额定输出的攻略在7000瓦左右，运行起来非常的安全，可以实现预期每一个地方的功能，而且非常利于推动电动汽车行业的发展。关键词：电动汽车；充电站；PLC；系统。Intelligent Charging Station of Electric Vehicle Based on PLCAbsrtact: With the continuous development of society, the demand for petroleum resources has become higher and higher, and there is a

4、very big contradiction between energy supply and demand. According to statistics, since 2012, the proportion of oil consumption of traditional fuel vehicles has reached 33.6%. Automobile exhaust is also one of the most important reasons for air pollution, so energy saving and emission reduction has

5、become a topic of increasing importance in every country and every automobile industry. Therefore, electric vehicles have been produced, electric vehicles have many advantages, such as zero emission, energy saving and so on. However, because the electric vehicle industry has become a goal of future

6、automobile development, the current process of Chinas charging stations and battery exchange stations and other new energy vehicle-based equipment has begun to be very slow. And the coverage has slowly become smaller, resulting in a lot of room for improvement of electric vehicles. The charging stat

7、ion of electric vehicle is studied and designed in this paper. This research is of great help to promote the electric vehicle industry. In this paper, the electric vehicle charging station studied in this paper, well, draw lessons from the very excellent electric vehicle charging station at home and

8、 abroad, some very mature experience and valuable experience, I have consulted a lot of relevant information, understand the development and research results of the electric vehicle charging station at home and abroad, and analyze the advantages and disadvantages of the electric vehicle charging sta

9、tion. A series of overall plans about the charging station of EV are formulated. According to the analysis of the main control unit of the charging station of EV, it is found that programmable logic controller （PLC） can be used to select the hardware of the charging station of EV, and a very perfect

10、 control system of the charging station of EV is designed. As well as human-computer interaction module and dosimetry system module, voice module and print module, etc., not only successfully completed the control system software design and touch screen software design, as well as the communication

11、protocol design of each module, especially the PLC program design, so as to meet the data needs of each place. And it can realize and complete the design of charging station of electric vehicle continuously. At the same time, the radio frequency non-contact reading and writing mode is used to comple

12、te some functions of charging station billing system. The system management software developed independently can be used in this way, and the storage of data can be detected in the terminal device, as well as processing and analysis, which is convenient for managers to statistics and analysis. The e

13、lectric vehicle charging station developed in this paper has a protection system, besides short circuit protection and leakage protection, it also has an emergency button to stop charging in case of emergency danger. According to this design scheme. Electric vehicle charging station operation is ver

14、y simple, and the supply voltage is about 220 V. The strategy of rated output is about 7000W. It runs very safely. It can achieve the expected functions of every place, and is very conducive to promoting the development of electric vehicle industry.Key words: electric vehicle; charging station; PLC;
