锂电池性能一致性监测装置许强;周海洋;霍海波【摘要】为保证便携设备的正常使用,有必要对其内置锂电池进行实时监控.基于DS2438电池监测芯片开发的锂电池监控装置能实现锂电池状态实时监测,状态异常时通过蜂鸣器自动报警.该装置通过STM32微控制器控制DS2438电池管理芯片及其相应的外围电路,实现对锂电池温度、电流、电压及剩余容量的测量,能将数据通过串口通信传输到PC机.【期刊名称】《电源技术》【年(卷),期】2019(043)001【总页数】3页(P71-73)【关键词】锂离子电池组;一致性监测;STM32;DS2438【作者】许强;周海洋;霍海波【作者单位】上海海洋大学工程学院,上海200120;上海海洋大学工程学院,上海200120;上海海洋大学工程学院,上海200120【正文语种】中文【中图分类】TM912.9目前，大部分新能源汽车使用锂电池组，特斯拉就是其中一个例子，作为一款新能源汽车，2016年第三季度在美国的销售额已经超过了传统车型(如奔驰S系列、宝马7系列等)。

在环保要求不断提升的今天，驾乘电动汽车出行已经成为一种时代的趋势[1]。

锂离子电池电极由低密度的锂化合物和纯碳组成，所以很轻，比能量高。

离子电池没有记忆效应，使得锂离子电池日常使用维护简便。

但锂电池过放电时容易损坏，无法在较高温度环境下正常工作。

锂电池已经成为便携式设备首选电源，随着便携式设备增多，对锂电池的需求量越来越大。

对锂离子电池的监测可以确保锂电池在温度、电压、电流合适的情况下进行工作，所以对锂电池的监测很重要。

本文通过软件和硬件两部分的设计分析设计出了监测锂电池的装置，有一定的实际意义。

1 锂电池一致性当用电装置需要较大的能量和功率时，单只锂电池就无法满足要求，须多只单体电池串联并联。

单体电池串并联基础是电池性能一致性。

单体电池的一致性主要指电压、容量、内阻和自放电率的一致性。

1.1 容量一致性容量一致性是指配组单体之间容量偏差值保持在一个可接受范围内(如±1%)。

NI发布最小最轻便的测量设备将PDA转换成一个数据采NI发布最小、最轻便的测量设备, 将PDA转换成一个数据采集工具需要虚拟仪器专家的帮助吗？免费咨询电话:8008203622,或点击“请NI工程师回电，提供免费技术咨询！”新闻发布－2005年6月－工程师和科学家现在可以利用最新NI CompactFlash数据采集设备将标准PDA 转换成自定义的便携式测量工具。

尺寸仅比标准邮票大一点的NI CF-6004设备，可插入任何带有CompactFlash插槽的PDA，即可创建一个具有最新PDA设备处理和无线通信功能的手持式仪器。

NI CF-6004是一个14位的多功能数据采集设备，可以直接插入一个PDA CompactFlash插槽，从而在手持设备的四个模拟输入通道上提供了高达200KS/s的单通道采样性能。

该产品也提供了四条数字I/O线来控制和测量LVTTL 或LVCMOS信号。

工程师可以使用用于Pocket PC和Palm OS的NI LabVIEW图形化编程环境来在PDA上采集、分析和查看数据。

“CompactFlash数据采集设备的微型体积开拓了许多新型的便携式数据采集和监控应用。

”，NI研发部高级副总裁Tim Dehne先生说，“虚拟仪器技术就是让用户通过图形化编程和模块化硬件来自定义他们自己的仪器——正朝着小型化的方向发展，使得数据采集越来越便利、越来越轻便。

”NI CF-6004的灵活性和移动性使它成为诸如现场监控和诊断、实验室和教育设备之类应用的理想之选。

与购买几个传统的手持式仪器相比，工程师可以通过使用一个单一的带有LabVIEW 和NI CF-6004数据采集设备的PDA来节省宝贵的空间。

因为工程师可以在LabVIEW里定义他们自己特定的仪器然后轻松地应用到手持设备，所以他们也可以在日后作出改动，并重新配置这些应用来重新定义他们的PDA以用于新的测量。

此外，由于PDA通常比笔记本更加便宜，所以基于PDA的数据采集是手持式和便携式仪器的最佳选择。
