1、鋰電池Pack容量一致性原則

1C電(dian)(dian)(dian)(dian)流恒流充(chong)電(dian)(dian)(dian)(dian)至3.65V，轉(zhuan)3.65V恒電(dian)(dian)(dian)(dian)壓充(chong)電(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)流降為0.03Cs時(shi)停(ting)止。以1C電(dian)(dian)(dian)(dian)流放(fang)電(dian)(dian)(dian)(dian)，直到(dao)放(fang)電(dian)(dian)(dian)(dian)終止電(dian)(dian)(dian)(dian)壓2.0V，放(fang)電(dian)(dian)(dian)(dian)答量(liang)不低于額(e)定容(rong)量(liang)95%。

2、鋰電池Pack恒流比原則

以(yi)(yi)1C恒(heng)流(liu)放(fang)電(dian)(dian)(dian)(dian)至(zhi)2.0V，再以(yi)(yi)1C電(dian)(dian)(dian)(dian)流(liu)恒(heng)流(liu)充(chong)電(dian)(dian)(dian)(dian)至(zhi)3.65V，轉3.65V恒(heng)電(dian)(dian)(dian)(dian)壓充(chong)電(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)流(liu)降為0.03C時(shi)停(ting)止，恒(heng)流(liu)充(chong)入的電(dian)(dian)(dian)(dian)量與充(chong)入總電(dian)(dian)(dian)(dian)量之(zhi)比，充(chong)電(dian)(dian)(dian)(dian)恒(heng)流(liu)比不小于93%。

3、鋰電池Pack放電平(ping)臺要(yao)求

電池滿電后，以1C電流恒流放電至(zhi)2.0V，記(ji)錄電壓到3.1V的時(shi)間。放電平臺不少于48分

4、鋰電池Pack自放電要求

①滿電(dian)55℃士2℃的環(huan)境下貯存7d。②滿電(dian)25±5℃的環(huan)境下貯存28d。③不(bu)帶(dai)電(dian)45℃±2℃10天(tian)，測電(dian)壓(ya)。④不(bu)帶(dai)電(dian)25土5℃30天(tian)，測電(dian)壓(ya)。

荷電保持率不(bu)少于95%。開路(lu)電壓不(bu)小于2.80V。

5、鋰電(dian)池Pack內阻(zu)要求(qiu)：電(dian)芯內阻(zu)間誤差小于5mΩ；

6、鋰電(dian)(dian)池Pack電(dian)(dian)芯之間電(dian)(dian)壓(ya)差小于5mV;

7、鋰電池Pack電芯之間一致性越高(gao)越好；

8、鋰(li)電(dian)(dian)池Pack電(dian)(dian)芯的(de)循環壽命

①同(tong)(tong)批次材料、同(tong)(tong)一(yi)工藝(yi)、同(tong)(tong)一(yi)設備、同(tong)(tong)一(yi)時(shi)間生產的同(tong)(tong)型號電(dian)池(chi)可以(yi)組(zu)裝到同(tong)(tong)一(yi)電(dian)池(chi)組(zu)。②45土2℃環境下1C充放電(dian)，循環200次后(hou)，不少(shao)于初始(shi)1C5容量的95%。③品(pin)質部每批電(dian)池(chi)抽(chou)檢5只樣(yang)品(pin)進行測試，作為配當依據(ju)。

45士2℃環境下1C充放電，循(xun)環300次后，不少于初(chu)始1C；容量的95%。

鋰電(dian)(dian)(dian)池(chi)Pack的(de)成(cheng)組(zu)原則為：使用同(tong)(tong)(tong)一(yi)個(ge)檔(dang)欠的(de)電(dian)(dian)(dian)芯組(zu)裝，當某一(yi)批次(ci)該(gai)檔(dang)次(ci)的(de)電(dian)(dian)(dian)芯數量(liang)不夠時，使用相(xiang)鄰批次(ci)同(tong)(tong)(tong)檔(dang)電(dian)(dian)(dian)壓同(tong)(tong)(tong)檔(dang)容量(liang)的(de)電(dian)(dian)(dian)芯補足缺額。嚴(yan)禁不同(tong)(tong)(tong)電(dian)(dian)(dian)壓、不同(tong)(tong)(tong)內阻檔(dang)次(ci)電(dian)(dian)(dian)芯用于(yu)同(tong)(tong)(tong)一(yi)電(dian)(dian)(dian)池(chi)組(zu)的(de)組(zu)裝。
