信息(xi)来源：本(ben)站 日期：2017-11-06
电(dian)池(chi)能正常工(gong)作，很大(da)程度上得益于保护(hu)板(ban)，因(yin)而(er)保护(hu)板(ban)也有电(dian)池(chi)保护(hu)神(shen)之称.
锂(li)电(dian)池保护(hu)(hu)板主要由维护(hu)(hu)IC（过(guo)压维护(hu)(hu)）和MOS管（过(guo)流维护(hu)(hu)）构(gou)成，是用来(lai)保护(hu)(hu)锂(li)电(dian)池电(dian)芯安全的器材(cai)。锂(li)电(dian)池具有放电(dian)电(dian)流大、内阻(zu)低、寿数长、无回忆效应等(deng)被人们(men)广泛运(yun)(yun)用，锂(li)离子电(dian)池在运(yun)(yun)用中禁(jin)止过(guo)充电(dian)、过(guo)放电(dian)、短(duan)路，不然将(jiang)会使电(dian)池起火(huo)、爆破等(deng)丧(sang)命缺陷(xian)，所以，在运(yun)(yun)用可充锂(li)电(dian)池都(dou)会带有一块维护(hu)(hu)板来(lai)维护(hu)(hu)电(dian)芯的安全。
过充电保护(hu)板：保护(hu)板有(you)必要(yao)(yao)具(ju)有(you)防(fang)止电芯电压超越预设值(zhi)的(de)(de)才干过放电维护(hu)：保护(hu)板有(you)必要(yao)(yao)具(ju)有(you)防(fang)止电芯电压底于预设值(zhi)的(de)(de)才干。
(过流(liu)保(bao)护(hu)电流(liu)，短路保(bao)护(hu)）
保(bao)护(hu)板(ban)作为锂电(dian)芯的安全保(bao)护(hu)器材,既要在设备的正常作业电(dian)流规模内,能可靠工(gong)作，又要在当电(dian)池被意外短路或过流时能迅速(su)动作,使电(dian)芯得到保(bao)护(hu)。
定义：当充电电流为(wei)500mA时，MOS管的导通阻抗(kang)。
由于通讯设(she)备的(de)(de)(de)工作频率较高，数据(ju)传输要求误(wu)码率低(di)，其脉冲串(chuan)的(de)(de)(de)上升及(ji)下降沿陡，故对电池的(de)(de)(de)电流输出能力和电压稳定度(du)要求高，因(yin)而保护(hu)板(ban)的(de)MOS管开关导(dao)通(tong)时电阻要小，单节电芯保护(hu)板(ban)通(tong)常在<70mΩ，如太大会导(dao)致(zhi)通(tong)讯设备(bei)作业不正常，如手机在通(tong)话(hua)时突然断线、电话(hua)接不通(tong)、噪声等现象。
定义：IC作业电压(ya)为(wei)3。6V，空(kong)载状(zhuang)况(kuang)下，流经保护(hu)IC的作业电流，一般(ban)极(ji)小。
保(bao)护板(ban)的自(zi)耗(hao)电(dian)流(liu)直接影响电(dian)池的待机时(shi)刻，通常规则保(bao)护板(ban)的自(zi)耗(hao)电(dian)流(liu)小于10微安。
保护板有必要能通过国标规则的轰动,冲击(ji)实验;保护板在40到85度能安全工作,能经受±15KV的非触摸ESD静电测验。

首要要依据自己电(dian)(dian)(dian)(dian)(dian)机功率（需(xu)求(qiu)实践功率，一(yi)(yi)般骑行速度会(hui)(hui)对(dui)应(ying)(ying)一(yi)(yi)个相应(ying)(ying)实践功率）来(lai)核算电(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)需(xu)求(qiu)供(gong)(gong)给(ji)(ji)的(de)(de)继续电(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)。比(bi)方(fang)电(dian)(dian)(dian)(dian)(dian)机继续电(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)20a（48v下(xia)(xia)1000w电(dian)(dian)(dian)(dian)(dian)机），那(nei)么(me)就需(xu)求(qiu)电(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)能够长时(shi)刻(ke)供(gong)(gong)给(ji)(ji)20a电(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)而温升很(hen)低（哪怕夏日外面35度温度，电(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)温度也最(zui)好操控在50度以下(xia)(xia)）。别(bie)的(de)(de)如果48v下(xia)(xia)20a电(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)，超(chao)压一(yi)(yi)倍（96v，比(bi)方(fang)ecpu3档）后继续电(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)到50a左右。如果喜爱长时(shi)刻(ke)超(chao)压运用，那(nei)么(me)请选用能继续供(gong)(gong)给(ji)(ji)50a电(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)的(de)(de)电(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)（仍(reng)是留(liu)意(yi)温升问题）。这儿的(de)(de)电(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)继续电(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)不是商家标称(cheng)的(de)(de)电(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)放(fang)电(dian)(dian)(dian)(dian)(dian)才(cai)干(gan)。商家标称(cheng)几(ji)C（或几(ji)十几(ji)百安培）都是电(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)放(fang)电(dian)(dian)(dian)(dian)(dian)才(cai)干(gan)，而真的(de)(de)在这种电(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)下(xia)(xia)放(fang)电(dian)(dian)(dian)(dian)(dian)，电(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)发热很(hen)严(yan)峻的(de)(de)，如果不做(zuo)好散(san)热，电(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)寿数会(hui)(hui)很(hen)短。（而我们电(dian)(dian)(dian)(dian)(dian)动车运用电(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)环境(jing)是电(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)扎堆排放(fang)，根(gen)本不留(liu)空隙，包的(de)(de)很(hen)严(yan)实，更别(bie)提怎样做(zuo)好强行风冷(leng)散(san)热了）。我们的(de)(de)运用环境(jing)很(hen)恶劣(lie)。电(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)放(fang)电(dian)(dian)(dian)(dian)(dian)电(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)需(xu)降额运用。评估电(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)放(fang)电(dian)(dian)(dian)(dian)(dian)电(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)才(cai)干(gan)就是看这个电(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)下(xia)(xia)电(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)对(dui)应(ying)(ying)温升是多少(shao)。
这(zhei)儿论说的仅(jin)有准则(ze)其实(shi)是(shi)(shi)运(yun)用进程中(zhong)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)池的温(wen)升（高温(wen)是(shi)(shi)锂电(dian)(dian)(dian)(dian)(dian)(dian)(dian)寿数死敌）。最好电(dian)(dian)(dian)(dian)(dian)(dian)(dian)池温(wen)度(du)操(cao)控在50度(du)以(yi)下。（20-30度(du)之间最好）。这(zhei)也意(yi)味着如果(guo)是(shi)(shi)容量型(xing)锂电(dian)(dian)(dian)(dian)(dian)(dian)(dian)（操(cao)控在0.5C以(yi)下放(fang)(fang)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)），供给20a的继(ji)续放(fang)(fang)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)流需求(qiu)40ah以(yi)上容量（当然最主要是(shi)(shi)要看电(dian)(dian)(dian)(dian)(dian)(dian)(dian)池内(nei)阻(zu)）。如果(guo)是(shi)(shi)动(dong)力型(xing)锂电(dian)(dian)(dian)(dian)(dian)(dian)(dian)，依(yi)照1C继(ji)续放(fang)(fang)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)是(shi)(shi)正常的。哪(na)怕A123超(chao)低内(nei)阻(zu)动(dong)力型(xing)锂电(dian)(dian)(dian)(dian)(dian)(dian)(dian)，也平常最好在1C放(fang)(fang)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)（不超(chao)越(yue)2C为好，2C放(fang)(fang)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)其实(shi)只能放(fang)(fang)半个小时就没(mei)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)了，没(mei)太(tai)大运(yun)用价值(zhi)）。容量选择就看车子存放(fang)(fang)空间巨细(xi)，个人(ren)开销预算，希望(wang)车子活动(dong)规模巨细(xi)等要素。（小容量的一般有必要动(dong)力型(xing)锂电(dian)(dian)(dian)(dian)(dian)(dian)(dian)）
串联(lian)(lian)运(yun)用锂电(dian)(dian)(dian)的(de)大(da)(da)忌是(shi)电(dian)(dian)(dian)池(chi)(chi)自(zi)放(fang)(fang)电(dian)(dian)(dian)严(yan)峻不(bu)(bu)均衡。只(zhi)需我们(men)都一样(yang)不(bu)(bu)均衡没联(lian)(lian)系，问题是(shi)这(zhei)种状(zhuang)况是(shi)急(ji)不(bu)(bu)稳定(ding)状(zhuang)况，好(hao)(hao)的(de)电(dian)(dian)(dian)池(chi)(chi)自(zi)放(fang)(fang)电(dian)(dian)(dian)很小(xiao)，要坏(huai)的(de)电(dian)(dian)(dian)池(chi)(chi)自(zi)放(fang)(fang)电(dian)(dian)(dian)很大(da)(da)，自(zi)放(fang)(fang)电(dian)(dian)(dian)不(bu)(bu)小(xiao)不(bu)(bu)大(da)(da)的(de)状(zhuang)况一般(ban)是(shi)由好(hao)(hao)转坏(huai)的(de)状(zhuang)况，这(zhei)个进(jin)程是(shi)不(bu)(bu)稳定(ding)的(de)。所以需求把(ba)自(zi)放(fang)(fang)电(dian)(dian)(dian)大(da)(da)的(de)电(dian)(dian)(dian)池(chi)(chi)选择出来，只(zhi)留(liu)自(zi)放(fang)(fang)电(dian)(dian)(dian)小(xiao)的(de)电(dian)(dian)(dian)池(chi)(chi)配组(zu)（一般(ban)合(he)格(ge)品自(zi)放(fang)(fang)电(dian)(dian)(dian)都小(xiao)，厂家是(shi)测(ce)量过的(de)，问题是(shi)很多不(bu)(bu)合(he)格(ge)品流(liu)入商场）。
在(zai)自放电(dian)(dian)(dian)小(xiao)的(de)(de)基础上，选择容(rong)(rong)(rong)量(liang)(liang)(liang)邻近的(de)(de)串(chuan)联。即便容(rong)(rong)(rong)量(liang)(liang)(liang)不邻近也(ye)不会影响电(dian)(dian)(dian)池(chi)(chi)(chi)(chi)寿(shou)数(shu)，可是(shi)(shi)会影响整组(zu)电(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)可用容(rong)(rong)(rong)量(liang)(liang)(liang)，比方15个(ge)容(rong)(rong)(rong)量(liang)(liang)(liang)是(shi)(shi)20ah，只1个(ge)是(shi)(shi)18ah，那么这组(zu)电(dian)(dian)(dian)池(chi)(chi)(chi)(chi)总容(rong)(rong)(rong)量(liang)(liang)(liang)只能是(shi)(shi)18ah。用到最终会是(shi)(shi)这个(ge)电(dian)(dian)(dian)池(chi)(chi)(chi)(chi)没电(dian)(dian)(dian)了(le)，维护(hu)板要(yao)维护(hu)了(le)，整组(zu)电(dian)(dian)(dian)池(chi)(chi)(chi)(chi)电(dian)(dian)(dian)压(ya)还比较高（由于其它(ta)15个(ge)电(dian)(dian)(dian)池(chi)(chi)(chi)(chi)电(dian)(dian)(dian)压(ya)是(shi)(shi)正常的(de)(de)，还有电(dian)(dian)(dian)）。所以整组(zu)电(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)放电(dian)(dian)(dian)维护(hu)电(dian)(dian)(dian)压(ya)凹(ao)凸能看(kan)出整组(zu)电(dian)(dian)(dian)池(chi)(chi)(chi)(chi)容(rong)(rong)(rong)量(liang)(liang)(liang)是(shi)(shi)否一起（条件是(shi)(shi)整组(zu)电(dian)(dian)(dian)池(chi)(chi)(chi)(chi)满(man)电(dian)(dian)(dian)的(de)(de)时(shi)分有必要(yao)每个(ge)电(dian)(dian)(dian)芯都充溢电(dian)(dian)(dian)了(le)）。总归，容(rong)(rong)(rong)量(liang)(liang)(liang)凹(ao)凸不均衡(heng)不影响电(dian)(dian)(dian)池(chi)(chi)(chi)(chi)寿(shou)数(shu)，仅仅影响整组(zu)容(rong)(rong)(rong)量(liang)(liang)(liang)，所以尽量(liang)(liang)(liang)选择容(rong)(rong)(rong)量(liang)(liang)(liang)邻近的(de)(de)拼装(zhuang)。
拼装电(dian)(dian)(dian)(dian)(dian)池有必要做到电(dian)(dian)(dian)(dian)(dian)极(ji)间良好的(de)欧姆触摸(mo)电(dian)(dian)(dian)(dian)(dian)阻(zu)。就是(shi)电(dian)(dian)(dian)(dian)(dian)线和电(dian)(dian)(dian)(dian)(dian)极(ji)触摸(mo)电(dian)(dian)(dian)(dian)(dian)阻(zu)越小越好，不然触摸(mo)电(dian)(dian)(dian)(dian)(dian)阻(zu)大电(dian)(dian)(dian)(dian)(dian)极(ji)会(hui)发(fa)热，这(zhei)个(ge)热量会(hui)顺着电(dian)(dian)(dian)(dian)(dian)极(ji)传递(di)给电(dian)(dian)(dian)(dian)(dian)芯内部影响电(dian)(dian)(dian)(dian)(dian)池寿数(shu)。当(dang)然拼装电(dian)(dian)(dian)(dian)(dian)阻(zu)大的(de)体现(xian)就是(shi)相同放电(dian)(dian)(dian)(dian)(dian)电(dian)(dian)(dian)(dian)(dian)流下电(dian)(dian)(dian)(dian)(dian)池组压降(jiang)大。（压降(jiang)一部分是(shi)电(dian)(dian)(dian)(dian)(dian)芯内阻(zu)，一部分是(shi)拼装的(de)触摸(mo)电(dian)(dian)(dian)(dian)(dian)阻(zu)和电(dian)(dian)(dian)(dian)(dian)线电(dian)(dian)(dian)(dian)(dian)阻(zu)）

保护板(ban)(ban)(ban)意图是用来保护电池防止(zhi)过(guo)充(chong)电和过(guo)放电，防止(zhi)大(da)电流损坏电池，而且满电时做(zuo)电池电压均(jun)衡(heng)（均(jun)衡(heng)才干一般都比(bi)较小(xiao)，所以(yi)如(ru)果有自放电大(da)的(de)电芯保护板(ban)(ban)(ban)是很难均(jun)衡(heng)的(de)，也有任(ren)何状况(kuang)都做(zuo)均(jun)衡(heng)的(de)保护板(ban)(ban)(ban)，就是从开端(duan)充(chong)电就做(zuo)均(jun)衡(heng)，好像很少）。

保护板(ban)的内阻(zu)(zu)越(yue)(yue)低越(yue)(yue)好，越(yue)(yue)低越(yue)(yue)不发热。保护板(ban)限流巨细(xi)是靠康铜(tong)丝取样(yang)电阻(zu)(zu)决议(yi)的，但继续电流才干是mos决议(yi)的（由(you)于(yu)mos内阻(zu)(zu)决议(yi)温升）。
