毕业设计（论文）-纯电动汽车电池管理系统(bms).doc

1摘摘 要要随着工业发展和社会需求的增加，汽车在社会进步和经济发展中扮演着重要的角色汽车工业的迅速发展，推动了机械、能源、橡胶、钢铁等重要产业的发展，但同时也日益面临着环境污染、能源短缺的严重问题纯电动汽车以其零排放，噪声低等优点越来越受到世界各国的重视，被称作绿色环保车作为发展电动车的关键技术之一的电池管理系统(BMS)，是纯电动车产业化的关键车载网络数据采集系统就是这样一个电池管理系统，可以直接检测及管理电动汽车的储能电池运行的全过程，实现对车载多级串联锂电池、电池温度、车速等数据的监测、采集和分析本论文是基于 CAN 总线的车载网络数据采集系统选用 STM32F103VB 作为系统的核心芯片，通过芯片自带的 12 位 ADC 对端口电压分别进行采集和监测，并通过 CAN 网络将采集到的数据发送到汽车仪表盘，为车辆状态量实时监测提供数据来源关键词关键词：纯电动车，电池管理系统，电池状态，STM32F103VB2AbstractWith industrial development and social demand, vehicle of social progress and economic development play important roles. Although the rapid development of automobile industry promote the machinery, energy, rubber, steel and other important industries, it is increasingly faced with environmental pollution, energy shortages and other serious problems. With the merit of zero-emission, and low noise, the pure electric vehicles which is called green cars has got more and more attention around the world. As one of the key technologies for the development of electric vehicles ,battery management system (BMS) is the point of the pure electric vehicle industry. Vehicle network data acquisition system is a battery management system that can directly detect and manage the storage battery electric vehicles to run the whole process, to achieve the data monitoring, collection and analysis of the on-board multi-level series of lithium battery, battery temperature, speed, and other The thesis is based on the vehicle CAN bus data acquisition system to chose STM32F103VB network as the core of the system chip.12-bit ADC which comes from the chip collect and monitor the port voltages and sent the collected data to the car dashboard through the CAN network , which offer real-time monitoring of vehicle status amount of data sources. Key words：：Pure electric cars, Battery Management Systems, The battery state, STM32F103VB3摘 要..............................................................................................................................................1 Abstract ............................................................................................................................................2第一章 前言................................................................................................................................5 1.1 本课题研究的目的和意义.............................................................................................5 1.2 车载网络数据采集系统的国内外研究现状.................................................................6 1.3 本论文研究的主要工作.................................................................................................7 第二章 车载网络数据采集系统设计的原理...............................................................................9 2.1 车载网络数据采集系统的功能概述...............................................................................9 2.1.1 车载网络数据采集系统的结构.......................................................................10 2.1.2 基于 STM32 的车在网络数据采集系统设计控制框图...................................10 2.2 信号的采集与处理 ......................................................................................................11 2.3 车载系统的网络通讯 ....................................................................................................12 2.3.1 CAN 网络的基本概念........................................................................................12 2.3.2 CAN 网络在车载数据采集系统中的应用........................................................13 2.3.3 系统主要性能指标...........................................................................................14 2.4 系统预期误差的评估 ..................................................................................................15 第三章 基于 STM32F103VB 数据采集系统的硬件设计...............................................................16 3.1 STM32F103VB 简介 .........................................................................................................16 3.2 STM32F103VB 电源模块的设计....................................................................................17 3.2.1 电源电路的设计.................................................................................................17 3.2.2 STM32 启动模式电路选择设计..........................................................................18 3.3 STM32F103VB 外围接口电路的设计............................................................................19 3.3.1 模数转换器的电路设计.....................................................................................19 3.3.2 测温电路设计 ..................................................................................................20 3.3.3 复位电路的电路设计.......................................................................................21 3.4 STM32F103B 通讯电路的设计........................................................................................21 3.4.1 CAN 通讯接口电路设计......................................................................................21 3.4.2 JTAG 程序调试接口电路设计..........................................................................22 3.4.3 RS485 通讯电路设计...........................................................。
