电池能(neng)正常工作，很大程度上(shang)得(de)益于保(bao)护板(ban)，因而保(bao)护板(ban)也有电池保(bao)护神之称.
锂(li)(li)电(dian)(dian)(dian)池(chi)(chi)保护(hu)板主要(yao)由(you)维(wei)(wei)护(hu)IC（过(guo)压维(wei)(wei)护(hu)）和MOS管（过(guo)流(liu)维(wei)(wei)护(hu)）构(gou)成，是用(yong)来保护(hu)锂(li)(li)电(dian)(dian)(dian)池(chi)(chi)电(dian)(dian)(dian)芯(xin)安全(quan)的器材(cai)。锂(li)(li)电(dian)(dian)(dian)池(chi)(chi)具(ju)有放电(dian)(dian)(dian)电(dian)(dian)(dian)流(liu)大(da)、内阻低、寿数长、无回忆效应等被(bei)人们广泛运(yun)(yun)用(yong)，锂(li)(li)离子电(dian)(dian)(dian)池(chi)(chi)在运(yun)(yun)用(yong)中禁(jin)止过(guo)充电(dian)(dian)(dian)、过(guo)放电(dian)(dian)(dian)、短路，不然将会使(shi)电(dian)(dian)(dian)池(chi)(chi)起火、爆破等丧命缺(que)陷(xian)，所(suo)以，在运(yun)(yun)用(yong)可(ke)充锂(li)(li)电(dian)(dian)(dian)池(chi)(chi)都会带有一(yi)块维(wei)(wei)护(hu)板来维(wei)(wei)护(hu)电(dian)(dian)(dian)芯(xin)的安全(quan)。

(过流保护电(dian)流，短路保护）
保(bao)护(hu)板作(zuo)(zuo)为锂电(dian)(dian)芯的安(an)全保(bao)护(hu)器材,既要在设备的正常(chang)作(zuo)(zuo)业电(dian)(dian)流(liu)规(gui)模内(nei),能可(ke)靠工(gong)作(zuo)(zuo)，又(you)要在当电(dian)(dian)池(chi)被意外(wai)短路或过(guo)流(liu)时能迅速动作(zuo)(zuo),使(shi)电(dian)(dian)芯得(de)到保(bao)护(hu)。
定义(yi)：当充电电流为500mA时，MOS管的导通阻抗。
由于(yu)通讯设备的工作频(pin)率较高，数据传(chuan)输要求误码率低，其脉(mai)冲串(chuan)的上(shang)升及下(xia)降沿陡，故对电(dian)(dian)池的电(dian)(dian)流输出能力和电(dian)(dian)压(ya)稳定度要求高，因而保护板的MOS管开关导通(tong)时电(dian)阻要小，单(dan)节电(dian)芯保护板通(tong)常在<70mΩ，如太大会导致(zhi)通(tong)讯(xun)设备作(zuo)业不正常，如手机在通(tong)话时突然(ran)断线、电(dian)话接不通(tong)、噪声(sheng)等(deng)现象。
定义：IC作(zuo)业(ye)电(dian)压(ya)为(wei)3。6V，空载状况下，流(liu)(liu)经保(bao)护IC的作(zuo)业(ye)电(dian)流(liu)(liu)，一般极小。
保(bao)护(hu)板的自耗电(dian)流(liu)直接影响电(dian)池的待机(ji)时(shi)刻，通(tong)常(chang)规则(ze)保(bao)护(hu)板的自耗电(dian)流(liu)小于(yu)10微安。
保(bao)护板(ban)有必要(yao)能通(tong)过国标规则的轰动,冲击(ji)实验;保(bao)护板(ban)在(zai)40到85度能安全工作(zuo),能经受±15KV的非触摸ESD静电(dian)测验。

过充保护：在给产品充电(dian)(dian)时，电(dian)(dian)压(ya)到达电(dian)(dian)池(chi)最高(gao)电(dian)(dian)压(ya)（4.2V）时，保护板就会(hui)主动断电(dian)(dian)封闭，显现(xian)充溢不(bu)在继续充电(dian)(dian)了。构(gou)成的一(yi)种过充保护效果(guo)。

首要要依据自己电(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)功(gong)(gong)(gong)率（需求(qiu)实(shi)践功(gong)(gong)(gong)率，一(yi)般(ban)骑行(xing)速度(du)(du)会对(dui)应(ying)一(yi)个相应(ying)实(shi)践功(gong)(gong)(gong)率）来核算电(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)需求(qiu)供给(ji)的(de)(de)继(ji)续(xu)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)流。比(bi)方电(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)继(ji)续(xu)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)流20a（48v下(xia)1000w电(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)），那么就需求(qiu)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)能够长时(shi)刻供给(ji)20a电(dian)(dian)(dian)(dian)(dian)(dian)(dian)流而温(wen)升很(hen)低（哪怕夏日外面35度(du)(du)温(wen)度(du)(du)，电(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)温(wen)度(du)(du)也最好操控(kong)在50度(du)(du)以下(xia)）。别的(de)(de)如果(guo)48v下(xia)20a电(dian)(dian)(dian)(dian)(dian)(dian)(dian)流，超压一(yi)倍（96v，比(bi)方ecpu3档）后继(ji)续(xu)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)流到50a左右。如果(guo)喜爱长时(shi)刻超压运(yun)用，那么请选用能继(ji)续(xu)供给(ji)50a电(dian)(dian)(dian)(dian)(dian)(dian)(dian)流的(de)(de)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)（仍是留(liu)意温(wen)升问(wen)题）。这儿的(de)(de)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)继(ji)续(xu)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)流不是商(shang)家标(biao)称的(de)(de)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)放(fang)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)才(cai)(cai)干(gan)。商(shang)家标(biao)称几(ji)C（或几(ji)十几(ji)百(bai)安培）都是电(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)放(fang)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)才(cai)(cai)干(gan)，而真(zhen)的(de)(de)在这种电(dian)(dian)(dian)(dian)(dian)(dian)(dian)流下(xia)放(fang)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)，电(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)发热(re)很(hen)严(yan)峻的(de)(de)，如果(guo)不做(zuo)好散热(re)，电(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)寿数(shu)会很(hen)短。（而我(wo)们电(dian)(dian)(dian)(dian)(dian)(dian)(dian)动车运(yun)用电(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)环境是电(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)扎堆排放(fang)，根本不留(liu)空隙，包(bao)的(de)(de)很(hen)严(yan)实(shi)，更(geng)别提怎样做(zuo)好强行(xing)风冷散热(re)了）。我(wo)们的(de)(de)运(yun)用环境很(hen)恶劣(lie)。电(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)放(fang)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)流需降额运(yun)用。评估电(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)放(fang)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)流才(cai)(cai)干(gan)就是看这个电(dian)(dian)(dian)(dian)(dian)(dian)(dian)流下(xia)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)对(dui)应(ying)温(wen)升是多(duo)少。
这儿论说的(de)仅有准则其实是(shi)(shi)(shi)运(yun)用进(jin)程中(zhong)电(dian)(dian)池的(de)温(wen)升（高温(wen)是(shi)(shi)(shi)锂(li)电(dian)(dian)寿数死(si)敌(di)）。最好(hao)电(dian)(dian)池温(wen)度操控在50度以(yi)下。（20-30度之间最好(hao)）。这也意味着如果是(shi)(shi)(shi)容(rong)(rong)量型(xing)锂(li)电(dian)(dian)（操控在0.5C以(yi)下放电(dian)(dian)），供给(ji)20a的(de)继续放电(dian)(dian)电(dian)(dian)流(liu)需求40ah以(yi)上容(rong)(rong)量（当(dang)然最主要(yao)是(shi)(shi)(shi)要(yao)看电(dian)(dian)池内(nei)阻(zu)）。如果是(shi)(shi)(shi)动力型(xing)锂(li)电(dian)(dian)，依照1C继续放电(dian)(dian)是(shi)(shi)(shi)正常的(de)。哪怕A123超低内(nei)阻(zu)动力型(xing)锂(li)电(dian)(dian)，也平常最好(hao)在1C放电(dian)(dian)（不超越2C为好(hao)，2C放电(dian)(dian)其实只能放半(ban)个(ge)小(xiao)时就(jiu)没(mei)电(dian)(dian)了，没(mei)太大运(yun)用价值）。容(rong)(rong)量选择就(jiu)看车(che)子存放空间巨细，个(ge)人(ren)开销预算(suan)，希望车(che)子活动规模巨细等要(yao)素。（小(xiao)容(rong)(rong)量的(de)一般有必(bi)要(yao)动力型(xing)锂(li)电(dian)(dian)）
串联运(yun)用锂电的大(da)(da)(da)忌是(shi)(shi)电池自放(fang)(fang)电严峻不(bu)(bu)均(jun)衡(heng)。只(zhi)需我们(men)都一样不(bu)(bu)均(jun)衡(heng)没(mei)联系，问题(ti)是(shi)(shi)这种状(zhuang)(zhuang)(zhuang)况(kuang)(kuang)是(shi)(shi)急(ji)不(bu)(bu)稳(wen)定状(zhuang)(zhuang)(zhuang)况(kuang)(kuang)，好的电池自放(fang)(fang)电很(hen)小，要坏(huai)的电池自放(fang)(fang)电很(hen)大(da)(da)(da)，自放(fang)(fang)电不(bu)(bu)小不(bu)(bu)大(da)(da)(da)的状(zhuang)(zhuang)(zhuang)况(kuang)(kuang)一般是(shi)(shi)由好转坏(huai)的状(zhuang)(zhuang)(zhuang)况(kuang)(kuang)，这个(ge)进(jin)程是(shi)(shi)不(bu)(bu)稳(wen)定的。所以需求把自放(fang)(fang)电大(da)(da)(da)的电池选(xuan)择(ze)出来(lai)，只(zhi)留自放(fang)(fang)电小的电池配(pei)组（一般合(he)格品(pin)自放(fang)(fang)电都小，厂家是(shi)(shi)测(ce)量过(guo)的，问题(ti)是(shi)(shi)很(hen)多不(bu)(bu)合(he)格品(pin)流入商场）。
在自放电小的(de)(de)基(ji)础上，选(xuan)择(ze)容(rong)(rong)量(liang)(liang)邻(lin)近的(de)(de)串联。即便容(rong)(rong)量(liang)(liang)不邻(lin)近也不会(hui)影响电池(chi)(chi)(chi)(chi)寿(shou)数，可是(shi)(shi)(shi)(shi)会(hui)影响整(zheng)组(zu)电池(chi)(chi)(chi)(chi)的(de)(de)可用容(rong)(rong)量(liang)(liang)，比(bi)方15个(ge)容(rong)(rong)量(liang)(liang)是(shi)(shi)(shi)(shi)20ah，只(zhi)1个(ge)是(shi)(shi)(shi)(shi)18ah，那么这组(zu)电池(chi)(chi)(chi)(chi)总容(rong)(rong)量(liang)(liang)只(zhi)能是(shi)(shi)(shi)(shi)18ah。用到最终(zhong)会(hui)是(shi)(shi)(shi)(shi)这个(ge)电池(chi)(chi)(chi)(chi)没(mei)电了，维护(hu)板(ban)要(yao)维护(hu)了，整(zheng)组(zu)电池(chi)(chi)(chi)(chi)电压还(hai)比(bi)较高（由于其它15个(ge)电池(chi)(chi)(chi)(chi)电压是(shi)(shi)(shi)(shi)正常的(de)(de)，还(hai)有电）。所以(yi)整(zheng)组(zu)电池(chi)(chi)(chi)(chi)的(de)(de)放电维护(hu)电压凹(ao)凸能看出整(zheng)组(zu)电池(chi)(chi)(chi)(chi)容(rong)(rong)量(liang)(liang)是(shi)(shi)(shi)(shi)否一起（条件是(shi)(shi)(shi)(shi)整(zheng)组(zu)电池(chi)(chi)(chi)(chi)满电的(de)(de)时分(fen)有必(bi)要(yao)每个(ge)电芯都充(chong)溢电了）。总归，容(rong)(rong)量(liang)(liang)凹(ao)凸不均衡(heng)不影响电池(chi)(chi)(chi)(chi)寿(shou)数，仅(jin)仅(jin)影响整(zheng)组(zu)容(rong)(rong)量(liang)(liang)，所以(yi)尽量(liang)(liang)选(xuan)择(ze)容(rong)(rong)量(liang)(liang)邻(lin)近的(de)(de)拼装。

保护(hu)板意(yi)图是用来(lai)保护(hu)电(dian)(dian)(dian)池防(fang)止过充(chong)电(dian)(dian)(dian)和过放电(dian)(dian)(dian)，防(fang)止大(da)电(dian)(dian)(dian)流(liu)损(sun)坏电(dian)(dian)(dian)池，而且满电(dian)(dian)(dian)时(shi)做电(dian)(dian)(dian)池电(dian)(dian)(dian)压均(jun)(jun)衡（均(jun)(jun)衡才(cai)干一般都比较(jiao)小，所以如果(guo)有自放电(dian)(dian)(dian)大(da)的(de)电(dian)(dian)(dian)芯(xin)保护(hu)板是很难均(jun)(jun)衡的(de)，也(ye)有任何状况都做均(jun)(jun)衡的(de)保护(hu)板，就(jiu)是从开端充(chong)电(dian)(dian)(dian)就(jiu)做均(jun)(jun)衡，好像很少）。
为了(le)电(dian)(dian)池组寿(shou)数(shu)，主张任(ren)何时分电(dian)(dian)池充电(dian)(dian)电(dian)(dian)压(ya)都不(bu)(bu)要超越3.6v，意味着维护板保(bao)护动作电(dian)(dian)压(ya)不(bu)(bu)高(gao)于3.6v，均衡电(dian)(dian)压(ya)主张3.4v-3.5v（每(mei)个电(dian)(dian)芯3.4v现已充进大于99%电(dian)(dian)量了(le)，指的停止状况，大电(dian)(dian)流充电(dian)(dian)时电(dian)(dian)压(ya)会升高(gao)）。电(dian)(dian)池放电(dian)(dian)保(bao)护电(dian)(dian)压(ya)一般2.5v以上就能够（2v以上问题不(bu)(bu)大，一般很少有时机用到彻底(di)没电(dian)(dian)，所(suo)以这个要求(qiu)不(bu)(bu)高(gao)）。
充(chong)电(dian)(dian)(dian)(dian)(dian)器主(zhu)张最高电(dian)(dian)(dian)(dian)(dian)压(ya)（最终一步充(chong)电(dian)(dian)(dian)(dian)(dian)能够为(wei)最高恒压(ya)充(chong)电(dian)(dian)(dian)(dian)(dian)形式）为(wei)3.5*串数，比(bi)方(fang)16串的(de)为(wei)56v左(zuo)右(you)。平(ping)常充(chong)电(dian)(dian)(dian)(dian)(dian)能够每节(jie)(jie)均(jun)(jun)匀3.4v截止充(chong)电(dian)(dian)(dian)(dian)(dian)（根本充(chong)溢了(le)），这样电(dian)(dian)(dian)(dian)(dian)池寿数有保证，可(ke)是(shi)由于保护板(ban)还(hai)没(mei)(mei)开端(duan)均(jun)(jun)衡(heng)(heng)(heng)，如果(guo)电(dian)(dian)(dian)(dian)(dian)芯(xin)有自(zi)放(fang)电(dian)(dian)(dian)(dian)(dian)大(da)的(de)，会随着时刻(ke)推移，体现为(wei)整组容(rong)量逐步下降(jiang)(jiang)。所以(yi)还(hai)需(xu)求定(ding)时（比(bi)方(fang)每周）把电(dian)(dian)(dian)(dian)(dian)池每节(jie)(jie)充(chong)到3.5v-3.6v并坚持几个小(xiao)时（只需(xu)均(jun)(jun)匀大(da)于均(jun)(jun)衡(heng)(heng)(heng)发(fa)(fa)动电(dian)(dian)(dian)(dian)(dian)压(ya)就(jiu)能够了(le)），自(zi)放(fang)电(dian)(dian)(dian)(dian)(dian)越大(da)，均(jun)(jun)衡(heng)(heng)(heng)需(xu)求时刻(ke)越长(zhang)，自(zi)放(fang)电(dian)(dian)(dian)(dian)(dian)过(guo)(guo)大(da)的(de)电(dian)(dian)(dian)(dian)(dian)芯(xin)现已很难均(jun)(jun)衡(heng)(heng)(heng)，需(xu)求除掉。所以(yi)选择(ze)保护板(ban)的(de)时分(fen)，尽量选择(ze)3.6v过(guo)(guo)压(ya)维护的(de)，3.5v左(zuo)右(you)发(fa)(fa)动均(jun)(jun)衡(heng)(heng)(heng)的(de)。（商(shang)场上(shang)大(da)部分(fen)是(shi)3.8v以(yi)上(shang)过(guo)(guo)压(ya)维护，3.6v以(yi)上(shang)发(fa)(fa)动均(jun)(jun)衡(heng)(heng)(heng)）。其实选择(ze)适宜均(jun)(jun)衡(heng)(heng)(heng)发(fa)(fa)动电(dian)(dian)(dian)(dian)(dian)压(ya)比(bi)维护电(dian)(dian)(dian)(dian)(dian)压(ya)还(hai)重要(yao)，由于最高电(dian)(dian)(dian)(dian)(dian)压(ya)能够靠调节(jie)(jie)充(chong)电(dian)(dian)(dian)(dian)(dian)器最高电(dian)(dian)(dian)(dian)(dian)压(ya)约束（就(jiu)是(shi)平(ping)常让维护板(ban)没(mei)(mei)时机(ji)(ji)做高压(ya)维护），但(dan)如果(guo)均(jun)(jun)衡(heng)(heng)(heng)电(dian)(dian)(dian)(dian)(dian)压(ya)高了(le)，电(dian)(dian)(dian)(dian)(dian)池组没(mei)(mei)时机(ji)(ji)均(jun)(jun)衡(heng)(heng)(heng)（除非(fei)充(chong)电(dian)(dian)(dian)(dian)(dian)电(dian)(dian)(dian)(dian)(dian)压(ya)大(da)于均(jun)(jun)衡(heng)(heng)(heng)电(dian)(dian)(dian)(dian)(dian)压(ya)，但(dan)这样影响电(dian)(dian)(dian)(dian)(dian)池寿数），电(dian)(dian)(dian)(dian)(dian)芯(xin)因自(zi)放(fang)电(dian)(dian)(dian)(dian)(dian)容(rong)量会慢(man)慢(man)下降(jiang)(jiang)（自(zi)放(fang)电(dian)(dian)(dian)(dian)(dian)为(wei)0的(de)抱负电(dian)(dian)(dian)(dian)(dian)芯(xin)是(shi)不存在的(de)）。
保护板(ban)(ban)继续放电(dian)(dian)(dian)电(dian)(dian)(dian)流(liu)(liu)才干。这(zhei)(zhei)个(ge)是(shi)最不(bu)好谈论的(de)东西。由(you)于单说维护板(ban)(ban)限流(liu)(liu)才干没含(han)义(yi)。比方一个(ge)75nf75管(guan)(guan)你让它继续通过50a电(dian)(dian)(dian)流(liu)(liu)（这(zhei)(zhei)时发热功率大概30w左右，同口板(ban)(ban)至少2个(ge)串联60w），只(zhi)需有(you)散(san)热片满(man)意散(san)热是(shi)没问题的(de)。能(neng)够(gou)一向坚(jian)持在(zai)50a乃至更高(gao)不(bu)烧管(guan)(guan)。可是(shi)你不(bu)能(neng)说这(zhei)(zhei)个(ge)保护板(ban)(ban)能(neng)继续50a电(dian)(dian)(dian)流(liu)(liu)。由(you)于我们的(de)保护板(ban)(ban)大多都放在(zai)电(dian)(dian)(dian)池盒里边和电(dian)(dian)(dian)池离的(de)很近(jin)，乃至是(shi)近(jin)靠着。所以这(zhei)(zhei)么高(gao)温度会导(dao)热电(dian)(dian)(dian)池升(sheng)温，问题来了(le)，高(gao)温是(shi)电(dian)(dian)(dian)池的(de)死敌(di)。
所以(yi)保(bao)(bao)护(hu)(hu)板(ban)(ban)的(de)运(yun)用环境(jing)决议了如何选择限流(liu)巨细（而(er)不(bu)是(shi)保(bao)(bao)护(hu)(hu)板(ban)(ban)自(zi)身电(dian)流(liu)才干(gan)）。如果是(shi)把保(bao)(bao)护(hu)(hu)板(ban)(ban)从电(dian)池盒(he)拿出来，那么(me)几乎随便一个带散热(re)片的(de)保(bao)(bao)护(hu)(hu)板(ban)(ban)都(dou)能搞定50a继续电(dian)流(liu)乃(nai)至(zhi)更高(gao)（这时只考(kao)虑(lv)保(bao)(bao)护(hu)(hu)板(ban)(ban)才干(gan)，不(bu)必忧虑(lv)温升(sheng)给电(dian)芯(xin)带来危害）。下面说说我(wo)们常用环境(jing)，就是(shi)和电(dian)池在同(tong)一个密(mi)闭空间里。这时保(bao)(bao)护(hu)(hu)板(ban)(ban)的(de)最(zui)大(da)发热(re)功率最(zui)好(hao)操控在10w以(yi)下（如果是(shi)小保(bao)(bao)护(hu)(hu)板(ban)(ban)需求(qiu)5w以(yi)下，大(da)体积保(bao)(bao)护(hu)(hu)板(ban)(ban)能够10w以(yi)上，由于自(zi)身散热(re)好(hao)，温度不(bu)会太(tai)高(gao)），至(zhi)于多少适宜，主张继续电(dian)流(liu)时整个板(ban)(ban)子最(zui)高(gao)温度不(bu)超(chao)越(yue)60度（50度以(yi)下最(zui)好(hao)）。理论上保(bao)(bao)护(hu)(hu)板(ban)(ban)温度越(yue)低(di)越(yue)好(hao)，对电(dian)芯(xin)越(yue)没(mei)影响。
