摘要
随着经济的发展, 电力电子设备的更新速度更是突飞猛进, 然而传统的能源煤, 石油, 天然气的储量却在日渐减少, 这样带来的能源问题就引起了广大用户的关注, 作为生活中的重要组成部分, 汽车越来越被称为了生活得必须品,能源的减少引发了汽车动力的改革, 而以电能代替传统的汽油的汽车便走进了人们的视野中, 它污染小, 对周围的影响也小。电动汽车的主要特色就是它的电池工程, 而对电池的管理系统也就成了试下研究的热点。电池管理系统作为电动汽车上不可缺少的一部分, 在对电动车的电池管理, 充放电控制, 电池监控等方面有着很重要的作用。
本课题拟以中国长安纯电动汽车的设计要求和主体设计规划为蓝本, 设计一款以单片机作为主要控制器的电池管理系统, 实现对电池的综合检测管理的设计。主要包括电压检测、电流检测、充电检测、放点检测, 并针对性的设计外围CAN总线接口电路, 以方便上级控制系统和我们设计的电池管理系统有机结合。

ABSTRACT
With the development of economy, the updating speed of power electronic equipment is advancing by leaps and bounds. However, the traditional energy of coal, oil, natural gas reserves but in dwindling, energy problem has caused attention of the majority of users, as an important part of life, more and more vehicles is known to life necessities, energy reduction caused by the reform of the electric vehicle, and the electrical energy takes the place of the traditional gasoline car went into people's field of vision, it little pollution, influence on the surrounding is small. The main feature of electric car is its battery engineering, and the battery management system has become a hot spot for the study. As an indispensable part of electric vehicle, battery management system plays an important role in battery management, charge discharge control, battery monitoring and so on..
This paper intends to China Changan pure electric vehicle design
requirements and the main planning and design is modeled, design a microcontroller as the main controller of the battery management system, the design and implementation of the overall detection of battery management. Mainly includes voltage detection, current detection, charging test and detection, and according to the design of peripheral interface circuit of CAN bus to superior control system and the design of battery management system, the organic combination of convenience.
Keywords : electric vehicles, charge management, lithium battery
