为了保证磷酸(suan)铁锂(li)电池(chi)(chi)(chi)组使用(yong)的(de)安全(quan)性(xing)和可靠性(xing)，开(kai)(kai)发和制造(zao)电池(chi)(chi)(chi)组协(xie)同管(guan)理系(xi)统(tong)至(zhi)关重(zhong)要。电池(chi)(chi)(chi)管(guan)理系(xi)统(tong)提供与充电电源、开(kai)(kai)关设备、负载、数据显示设备等外部系(xi)统(tong)交互(hu)的(de)接口(kou)。

虽然磷酸铁锂电(dian)(dian)(dian)池(chi)(chi)(chi)在短路、过充(chong)、挤压(ya)(ya)、针刺等情况(kuang)下仍是安全的(de)(de)(de)，但电(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)循环寿命(ming)会受到很大(da)影响(xiang)。磷酸铁锂电(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)生产(chan)工(gong)艺复杂(za)。单(dan)节电(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)一致性(xing)差会比密封(feng)阀控制的(de)(de)(de)铅酸电(dian)(dian)(dian)池(chi)(chi)(chi)大(da)，从而导致电(dian)(dian)(dian)池(chi)(chi)(chi)组在充(chong)电(dian)(dian)(dian)后期单(dan)个单(dan)节电(dian)(dian)(dian)池(chi)(chi)(chi)电(dian)(dian)(dian)压(ya)(ya)迅速上(shang)(shang)升，差值(zhi)过大(da)严(yan)重影响(xiang)电(dian)(dian)(dian)池(chi)(chi)(chi)寿命(ming)，为了避免(mian)上(shang)(shang)述(shu)现象的(de)(de)(de)发生，就需要(yao)通过电(dian)(dian)(dian)池(chi)(chi)(chi)管理系统来(lai)保(bao)证电(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)安全性(xing)和(he)可靠性(xing)。

电(dian)池(chi)(chi)(chi)管(guan)理系统(tong)(tong)(tong)是电(dian)池(chi)(chi)(chi)保护和管(guan)理的(de)(de)核心部件，不(bu)仅能确保电(dian)池(chi)(chi)(chi)的(de)(de)安全可(ke)靠使用，而且(qie)还能更好地发挥电(dian)池(chi)(chi)(chi)的(de)(de)性能和延长使用寿(shou)命(ming)，作(zuo)为通信(xin)的(de)(de)备用电(dian)能，管(guan)理系统(tong)(tong)(tong)起到了(le)高压直流电(dian)源(yuan)与(yu)电(dian)池(chi)(chi)(chi)之间的(de)(de)桥梁作(zuo)用。电(dian)池(chi)(chi)(chi)组管(guan)理系统(tong)(tong)(tong)必须满足通信(xin)供电(dian)系统(tong)(tong)(tong)的(de)(de)要(yao)(yao)求。因此，电(dian)池(chi)(chi)(chi)管(guan)理系统(tong)(tong)(tong)的(de)(de)安全管(guan)理模式对电(dian)池(chi)(chi)(chi)安全至关重要(yao)(yao)。电(dian)池(chi)(chi)(chi)组管(guan)理系统(tong)(tong)(tong)主要(yao)(yao)包括数据(ju)采(cai)集单元、计算与(yu)控制(zhi)单元、均(jun)衡单元、控制(zhi)执行单元和通信(xin)单元。
