一種可控溫電池超聲測試盒及測試系統的制造方法與工藝

本發明屬(shu)于電池測(ce)試技(ji)術,尤其是涉及一種(zhong)可(ke)控溫電池超聲(sheng)測(ce)試盒及測(ce)試系(xi)統。



背景技術:

電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)荷(he)電(dian)(dian)(dian)(dian)(dian)(dian)狀(zhuang)態(tai)(soc),也叫剩余(yu)電(dian)(dian)(dian)(dian)(dian)(dian)量,代(dai)表(biao)的(de)(de)(de)是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)使用一(yi)段時(shi)間或(huo)長期擱(ge)置不(bu)用后的(de)(de)(de)剩余(yu)容(rong)量與其(qi)完全充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)狀(zhuang)態(tai)的(de)(de)(de)容(rong)量的(de)(de)(de)比值。電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)健康狀(zhuang)態(tai)(soh),代(dai)表(biao)著(zhu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)當前性(xing)(xing)(xing)能(neng)同出廠性(xing)(xing)(xing)能(neng)的(de)(de)(de)比值。傳(chuan)統方法(fa)采用電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)與電(dian)(dian)(dian)(dian)(dian)(dian)壓來推算電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)荷(he)電(dian)(dian)(dian)(dian)(dian)(dian)狀(zhuang)態(tai)與健康狀(zhuang)態(tai)。然而(er)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)荷(he)電(dian)(dian)(dian)(dian)(dian)(dian)狀(zhuang)態(tai)和(he)健康狀(zhuang)態(tai)同其(qi)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)、電(dian)(dian)(dian)(dian)(dian)(dian)壓等可(ke)測(ce)量特性(xing)(xing)(xing)之間是(shi)一(yi)種非常復雜的(de)(de)(de)非線性(xing)(xing)(xing)關系,且(qie)隨(sui)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)使用環境和(he)使用工況而(er)變化,很難直接(jie)測(ce)得(de),因(yin)此,如何(he)準確(que)地進行電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)荷(he)電(dian)(dian)(dian)(dian)(dian)(dian)狀(zhuang)態(tai)的(de)(de)(de)測(ce)量是(shi)一(yi)個國際(ji)性(xing)(xing)(xing)的(de)(de)(de)難題。

于是(shi)(shi)人(ren)們嘗(chang)試對(dui)電池內部(bu)的(de)(de)(de)(de)變(bian)(bian)(bian)化(hua)(hua)進行直接分析(xi)(xi)。所(suo)采用的(de)(de)(de)(de)一(yi)(yi)種(zhong)分析(xi)(xi)方(fang)法(fa)(fa)主要是(shi)(shi)向電池中(zhong)引入光纖傳感器,通過(guo)光學性質的(de)(de)(de)(de)變(bian)(bian)(bian)化(hua)(hua)來推(tui)(tui)測電池內部(bu)的(de)(de)(de)(de)變(bian)(bian)(bian)化(hua)(hua)從(cong)而推(tui)(tui)測電池的(de)(de)(de)(de)soc。然而,這種(zhong)方(fang)法(fa)(fa)與(yu)現(xian)有的(de)(de)(de)(de)電池制作工(gong)藝并(bing)不兼(jian)容,容易破壞電池極(ji)片的(de)(de)(de)(de)涂布均勻性,且需(xu)要復雜的(de)(de)(de)(de)光譜(pu)分析(xi)(xi)設備(bei),無法(fa)(fa)大規(gui)模(mo)應用。另一(yi)(yi)種(zhong)分析(xi)(xi)方(fang)法(fa)(fa)是(shi)(shi)借助穿過(guo)電池的(de)(de)(de)(de)超聲(sheng)信(xin)號(hao)(hao)的(de)(de)(de)(de)變(bian)(bian)(bian)化(hua)(hua)來推(tui)(tui)測電池內部(bu)的(de)(de)(de)(de)變(bian)(bian)(bian)化(hua)(hua)從(cong)而推(tui)(tui)測電池的(de)(de)(de)(de)soc。當前,利用超聲(sheng)對(dui)電池內部(bu)變(bian)(bian)(bian)化(hua)(hua)研究(jiu)還(huan)處于剛剛興起階段。超聲(sheng)信(xin)號(hao)(hao)同電池變(bian)(bian)(bian)化(hua)(hua)的(de)(de)(de)(de)相關(guan)研究(jiu)十分稀少,缺乏專(zhuan)業(ye)的(de)(de)(de)(de)研究(jiu)設備(bei)。尤(you)其是(shi)(shi)超聲(sheng)信(xin)號(hao)(hao)受溫(wen)度(du)與(yu)探(tan)頭耦合狀態等干擾(rao)因素(su)的(de)(de)(de)(de)影響十分大。

1)通(tong)過上位機(ji)停止電池測試儀、超聲(sheng)信號發射/接收儀、溫控裝置2;

2)將電池從測(ce)試腔4內拔出,將測(ce)試腔4內的超聲耦合液(ye)倒(dao)出;

3)先將(jiang)超聲(sheng)波探頭(tou)(tou)3同(tong)超聲(sheng)信(xin)號發射(she)/接(jie)收儀斷開,從超聲(sheng)探頭(tou)(tou)安裝孔處旋轉取下。再旋轉安裝新的超聲(sheng)波探頭(tou)(tou)3;

4)將(jiang)電池插回測試盒(he),重(zhong)新(xin)灌入(ru)超(chao)聲耦(ou)合液至浸(jin)溫控裝置2;
