22、若所述性能傾(qing)(qing)向(xiang)(xiang)參量大(da)于(yu)或等(deng)于(yu)性能傾(qing)(qing)向(xiang)(xiang)參考值,則判斷所述性能傾(qing)(qing)向(xiang)(xiang)類型(xing)為異常傾(qing)(qing)向(xiang)(xiang)狀態;

23、若(ruo)所述性(xing)能(neng)傾(qing)向(xiang)參量小于性(xing)能(neng)傾(qing)向(xiang)參考(kao)值,則(ze)判(pan)斷所述性(xing)能(neng)傾(qing)向(xiang)類型為(wei)正常傾(qing)向(xiang)狀態。

24、進一步地,性(xing)能(neng)評估模塊根(gen)據所述(shu)電池(chi)(chi)回(hui)收(shou)方法和所述(shu)性(xing)能(neng)傾向類型確定回(hui)收(shou)電池(chi)(chi)的耐久性(xing),包括:

26、若所述電池回(hui)(hui)收(shou)方法(fa)為(wei)梯次(ci)利用但所述性(xing)能傾(qing)(qing)向類型為(wei)異常傾(qing)(qing)向狀(zhuang)態,則判斷回(hui)(hui)收(shou)電池的(de)耐久性(xing)不符合標準。

27、進一步地,信(xin)息(xi)采集模塊(kuai)還(huan)用于獲取回收電(dian)池(chi)的(de)歷史充(chong)(chong)放電(dian)信(xin)息(xi),所述歷史充(chong)(chong)放電(dian)信(xin)息(xi)包(bao)括(kuo)各(ge)次充(chong)(chong)電(dian)的(de)充(chong)(chong)電(dian)類(lei)型,所述充(chong)(chong)電(dian)類(lei)型包(bao)括(kuo)快充(chong)(chong)和慢充(chong)(chong),性能(neng)評估模塊(kuai)根(gen)據(ju)各(ge)充(chong)(chong)電(dian)類(lei)型對應的(de)充(chong)(chong)電(dian)次數之比和當前實際容量確定修正系數的(de)取值。
