動(dong)(dong)力(li)電(dian)(dian)池(chi)模(mo)組是由多個單體(ti)電(dian)(dian)芯(xin)串(chuan)并聯組裝而成(cheng)，單體(ti)電(dian)(dian)芯(xin)之間(jian)(jian)連(lian)(lian)接與(yu)緊固，要求連(lian)(lian)接片(pian)與(yu)電(dian)(dian)池(chi)的(de)(de)極柱接觸電(dian)(dian)阻小(xiao)、抗振動(dong)(dong)、牢靠程(cheng)度高。為了(le)保(bao)證成(cheng)組后的(de)(de)電(dian)(dian)池(chi)系統在電(dian)(dian)動(dong)(dong)車輛實際(ji)行(xing)駛過程(cheng)中的(de)(de)可(ke)靠性(xing)和(he)耐久度。在不同的(de)(de)動(dong)(dong)力(li)電(dian)(dian)池(chi)系統設計需求里，其體(ti)積(ji)能(neng)量(liang)密度、質量(liang)比能(neng)量(liang)密度以及體(ti)積(ji)功率密度等都會與(yu)動(dong)(dong)力(li)電(dian)(dian)池(chi)系統中單體(ti)電(dian)(dian)池(chi)之間(jian)(jian)連(lian)(lian)接結構與(yu)工藝相關。由于動(dong)(dong)力(li)電(dian)(dian)池(chi)模(mo)組是由多個單體(ti)電(dian)(dian)池(chi)連(lian)(lian)接組成(cheng)，而單體(ti)電(dian)(dian)池(chi)之間(jian)(jian)連(lian)(lian)接的(de)(de)方法和(he)工藝的(de)(de)選擇需根(gen)據電(dian)(dian)池(chi)類型(xing)及其極柱（極耳）的(de)(de)類型(xing)來定。

　　在一定(ding)程(cheng)度上(shang)，電(dian)(dian)(dian)芯(xin)的(de)性(xing)(xing)能(neng)決(jue)定(ding)了電(dian)(dian)(dian)池(chi)組的(de)性(xing)(xing)能(neng)進而(er)影響整個動(dong)力電(dian)(dian)(dian)池(chi)系統的(de)性(xing)(xing)能(neng)。因此在進行動(dong)力電(dian)(dian)(dian)池(chi)系統設計(ji)(ji)，一定(ding)要(yao)根據整車的(de)設計(ji)(ji)要(yao)求去選擇電(dian)(dian)(dian)芯(xin)的(de)材料(liao)及形狀。也就是說，匯(hui)(hui)流排也是電(dian)(dian)(dian)池(chi)一種進線的(de)連(lian)接(jie)方(fang)式，主要(yao)是增加了接(jie)觸(chu)面積，減少了耗能(neng)，降低了溫升。通用(yong)(yong)性(xing)(xing)好，實用(yong)(yong)性(xing)(xing)強(qiang)，具有安(an)全(quan)可靠，省(sheng)時(shi)簡便(bian)，導電(dian)(dian)(dian)性(xing)(xing)能(neng)好，接(jie)觸(chu)電(dian)(dian)(dian)阻低。電(dian)(dian)(dian)池(chi)模組常用(yong)(yong)的(de)匯(hui)(hui)流排有：鎳片、銅鋁(lv)復合匯(hui)(hui)流排、銅匯(hui)(hui)流排、總正總負(fu)匯(hui)(hui)流排、鋁(lv)匯(hui)(hui)流排，也會用(yong)(yong)到銅軟連(lian)接(jie)、鋁(lv)軟連(lian)接(jie)、銅箔(bo)軟連(lian)接(jie)等(deng)。
