【摘要】：传统的燃油汽车虽然给人们的日常生活和交通带来了巨大的便利,但同时也消耗着大量的燃油,并且排放出大量的尾气,使得能源危机和空气污染进一步加重,影响了人们的健康生存。在能源和环境问题的双重压力下,要保持汽车行业的可持续发展,研究环保和清洁的电动汽车势在必行。但是电动汽车的快速充电问题却成为其发展的主要瓶颈,本文的主要内容是研究电动汽车智能充电系统。本文以苏州市应用基础研究计划项目(工业部分)为依托,运用现代高频开关电源技术、PWM脉冲控制技术和ARM处理器,对电动汽车智能充电系统展开了研究和设计。论文研究的主要内容如下:(1)论文首先讨论了当前国内外对电动汽车充电系统的研究状况,并阐述了常用的电动汽车蓄电池的性能、充放电特性、充电方法以及控制技术。通过对传统充电方法和常规快速充电方法的对比分析,提出了分阶段正负脉冲充电,其负脉冲可以有效地消除蓄电池在充电过程中产生的极化现象。采用高频开关IGBT设计了主充电电路,详细的分析了整流、滤波电路、脉冲宽度调制电路的设计方法与工作原理。(2)论文设计了蓄电池监测电路,实时的监测蓄电池的端电压、充电电流和内部温度。根据蓄电池的实际充电状态来选择相应的充电参数能够有效的避免蓄电池发生过度充电。(3)采用Lab VIEW设计了上位机管理系统。对整个充电系统的状态进行监控,并将系统的充电数据保存至数据库。论文最后对系统主充电电路进行了仿真,并通过模拟充电参数完成了上位机管理系统的调试。根据仿真和调试结果,较好的达到了预定的设计要求。本文研究的电动汽车智能充电系统对电动汽车的发展具有一定的推动作用。
[Abstract]:Although the traditional fuel vehicles have brought great convenience to people's daily life and traffic, they also consume a lot of fuel and discharge a lot of exhaust gas, which makes the energy crisis and air pollution further aggravated, affecting the people's healthy survival. Under the dual pressure of energy and environment, it is necessary to maintain the automobile industry. It is imperative for the sustainable development of the electric vehicle to study the environmental protection and clean electric vehicles. However, the fast charging problem of the electric vehicle is the main bottleneck of its development. The main content of this paper is to study the intelligent charging system of the electric vehicle. This paper, based on the Suzhou application basic research project (industrial part), uses the modern high frequency switch. Power technology, PWM pulse control technology and ARM processor have been studied and designed for the intelligent charging system of electric vehicles. The main contents of this paper are as follows: (1) first, the research status of electric vehicle charging system at home and abroad is discussed, and the performance, charging and discharging characteristics and charging of the commonly used electric vehicle batteries are expounded. Method and control technology. Through comparison and analysis of traditional charging method and conventional fast charging method, a phased positive and negative pulse charge is proposed. The negative pulse can effectively eliminate the polarization of the battery during the charging process. The main charge circuit is designed by high frequency switch IGBT, and the rectifier and filter circuit are analyzed in detail. The design method and working principle of pulse width modulation circuit. (2) a battery monitoring circuit is designed in this paper to monitor the terminal voltage, charge current and internal temperature of the battery in real time. According to the actual charging state of the battery, the corresponding charging parameters can be effectively avoided. (3) the design of the battery is designed by Lab. The state of the whole charging system is monitored and the charge data of the system is saved to the database. Finally, the main charging circuit of the system is simulated, and the host computer management system is debugged through the simulation of the charging parameters. According to the simulation and the test results, the intended design is achieved. The intelligent charging system of electric vehicles in this paper has a certain role in promoting the development of electric vehicles.
