锂电(dian)池管(guan)理系统的主要模(mo)块(kuai)(kuai)有充电(dian)模(mo)块(kuai)(kuai)、数(shu)据采集模(mo)块(kuai)(kuai)、均衡(heng)模(mo)块(kuai)(kuai)、功(gong)率计算(suan)模(mo)块(kuai)(kuai)、数(shu)据显示(shi)模(mo)块(kuai)(kuai)和(he)存储通信(xin)模(mo)块(kuai)(kuai)等，起到(dao)电(dian)池管(guan)理和(he)保护作用。

锂电(dian)(dian)池(chi)管理系统(tong)利(li)用(yong)微机技术(shu)和检测技术(shu)，动(dong)态监测电(dian)(dian)池(chi)的运(yun)行(xing)状态，精(jing)准计算出电(dian)(dian)池(chi)的剩余电(dian)(dian)量还有多(duo)少，以便对电(dian)(dian)池(chi)进行(xing)充放(fang)电(dian)(dian)保护，确(que)保电(dian)(dian)池(chi)处于佳(jia)状态，节省运(yun)行(xing)成(cheng)本，延(yan)长电(dian)(dian)池(chi)的使用(yong)寿(shou)命。

锂(li)电(dian)池管理(li)(li)系统采用模(mo)块(kuai)化、分布式(shi)设计。该系统由两级控制结构组成，即本(ben)地(di)测(ce)量(liang)(liang)(liang)模(mo)块(kuai)和(he)中(zhong)央处(chu)理(li)(li)模(mo)块(kuai)。中(zhong)央处(chu)理(li)(li)模(mo)块(kuai)可(ke)通过RS232接口(kou)与(yu)上位机(ji)通信(xin)，并以CAN总线网络的(de)形(xing)式(shi)与(yu)本(ben)地(di)测(ce)量(liang)(liang)(liang)模(mo)块(kuai)通信(xin)。本(ben)地(di)测(ce)量(liang)(liang)(liang)模(mo)块(kuai)是(shi)为数据采集、充放(fang)电(dian)控制、电(dian)量(liang)(liang)(liang)测(ce)量(liang)(liang)(liang)、利(li)用CAN总线技术与(yu)中(zhong)央处(chu)理(li)(li)模(mo)块(kuai)通信(xin)。

锂电(dian)(dian)(dian)(dian)池(chi)管理系统内置(zhi)数据(ju)采集模块(kuai)，能采集电(dian)(dian)(dian)(dian)池(chi)的(de)各种参(can)数数据(ju)，如电(dian)(dian)(dian)(dian)流、电(dian)(dian)(dian)(dian)压(ya)、温度等参(can)数；充电(dian)(dian)(dian)(dian)模块(kuai)具有(you)预充电(dian)(dian)(dian)(dian)、恒流充电(dian)(dian)(dian)(dian)和(he)恒压(ya)充电(dian)(dian)(dian)(dian)三种模式，能按照采集的(de)参(can)数对(dui)(dui)电(dian)(dian)(dian)(dian)池(chi)进行(xing)放电(dian)(dian)(dian)(dian)控制；均衡模块(kuai)通过15W开(kai)关电(dian)(dian)(dian)(dian)源对(dui)(dui)单个电(dian)(dian)(dian)(dian)池(chi)进行(xing)均衡充电(dian)(dian)(dian)(dian)，让(rang)电(dian)(dian)(dian)(dian)池(chi)均衡一(yi)致(zhi)；电(dian)(dian)(dian)(dian)量(liang)估计单元主要(yao)对(dui)(dui)采集到的(de)状态参(can)数进行(xing)分析，并根据(ju)研究实验得(de)到的(de)电(dian)(dian)(dian)(dian)量(liang)估计算法对(dui)(dui)当前电(dian)(dian)(dian)(dian)池(chi)电(dian)(dian)(dian)(dian)量(liang)进行(xing)估计。
