市场上选择聚合物锂电池的原因

2022-04-18

聚(ju)合物锂电(dian)(dian)池是为(wei)电(dian)(dian)子设(she)备提供动(dong)力的(de)(de)(de)能源,可充电(dian)(dian)且容(rong)量很(hen)大。它们(men)的(de)(de)(de)各种排(pai)放速(su)率足以为(wei)一些苛刻的(de)(de)(de)设(she)备提供动(dong)力,使(shi)其成为(wei)镍(nie)镉(ge)(NiCd)电(dian)(dian)池等电(dian)(dian)池的(de)(de)(de)首要选择。

典型的聚合物锂电(dian)池(chi)(chi)(chi),无论电(dian)池(chi)(chi)(chi)编号(hao),都(dou)应该有两个(ge)主连(lian)(lian)(lian)(lian)接(jie)器(qi)(qi),即主连(lian)(lian)(lian)(lian)接(jie)器(qi)(qi)和(he)平衡连(lian)(lian)(lian)(lian)接(jie)器(qi)(qi)。主连(lian)(lian)(lian)(lian)接(jie)器(qi)(qi)可以(yi)用来快速(su)给电(dian)池(chi)(chi)(chi)充(chong)电(dian),但要牺牲(sheng)多个(ge)电(dian)池(chi)(chi)(chi)的电(dian)压平衡。它(ta)也是一个(ge)连(lian)(lian)(lian)(lian)接(jie)器(qi)(qi),直接(jie)插(cha)入实(shi)际的RC电(dian)子。正常(chang)情(qing)况(kuang)下,连(lian)(lian)(lian)(lian)接(jie)到连(lian)(lian)(lian)(lian)接(jie)器(qi)(qi)的红线为(wei)正,黑线为(wei)负(fu)。平衡连(lian)(lian)(lian)(lian)接(jie)器(qi)(qi)是导线较细的连(lian)(lian)(lian)(lian)接(jie)器(qi)(qi)。这个(ge)连(lian)(lian)(lian)(lian)接(jie)器(qi)(qi)插(cha)入一个(ge)电(dian)池(chi)(chi)(chi)充(chong)电(dian)器(qi)(qi),以(yi)平衡充(chong)电(dian),保持(chi)电(dian)池(chi)(chi)(chi)内的电(dian)池(chi)(chi)(chi)电(dian)压几乎相等(deng)。

聚合物锂电池(chi)主要有(you)五(wu)个(ge)参数(shu),具体如下:

1、电压;电压是电池内(nei)电动势(或电位差)的直接量度。它决定了电机(ji)的转速。

2、电池数(S评级):S是(shi)一组电池中电池单体的总数。

3、容(rong)量:容(rong)量是电池中储存(cun)的(de)“燃(ran)料”的(de)数(shu)量。容(rong)量越大(da),充电前的(de)运行(xing)时间(jian)就越长。

4、放电(dian)率:放电(dian)率(C级)与(yu)容(rong)量(liang)读数直(zhi)接相关。这(zhei)是一(yi)个衡量(liang)电(dian)池(chi)一(yi)次能(neng)被抽出多(duo)少容(rong)量(liang)的标准(zhun)。

5、C数:充电(C级)是可以安全地给电池充电的速率。
