本技術涉(she)(she)及車(che)輛電(dian)(dian)池(chi),尤其是(shi)涉(she)(she)及一種(zhong)動(dong)力電(dian)(dian)池(chi)的充電(dian)(dian)控制(zhi)方法及裝置(zhi)。
背景技術:
1、新能源汽車采用的鋰(li)離(li)子(zi)(zi)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)系統,在(zai)(zai)(zai)低溫(wen)環境下(xia)由于鋰(li)離(li)子(zi)(zi)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的電(dian)(dian)(dian)(dian)(dian)(dian)化學特性,低溫(wen)下(xia)允許充電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流較低導致(zhi)充電(dian)(dian)(dian)(dian)(dian)(dian)緩慢(man),低溫(wen)充電(dian)(dian)(dian)(dian)(dian)(dian)壽命(ming)衰減(jian)快,0℃以(yi)下(xia)甚至禁止(zhi)(zhi)充電(dian)(dian)(dian)(dian)(dian)(dian)。出(chu)于提高電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充電(dian)(dian)(dian)(dian)(dian)(dian)速度(du)、減(jian)緩電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)衰減(jian)等目(mu)的,需(xu)要對電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)包進行加熱。鋰(li)離(li)子(zi)(zi)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)在(zai)(zai)(zai)極低溫(wen)度(du)下(xia)也禁止(zhi)(zhi)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian),如某電(dian)(dian)(dian)(dian)(dian)(dian)芯(xin)在(zai)(zai)(zai)-30℃以(yi)下(xia)禁止(zhi)(zhi)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian),所以(yi)在(zai)(zai)(zai)此溫(wen)度(du)下(xia)對電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充電(dian)(dian)(dian)(dian)(dian)(dian)也需(xu)避免電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)誤放(fang)電(dian)(dian)(dian)(dian)(dian)(dian),同時用戶在(zai)(zai)(zai)充電(dian)(dian)(dian)(dian)(dian)(dian)時,電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)導致(zhi)soc不升反降,也影(ying)響體驗感和充電(dian)(dian)(dian)(dian)(dian)(dian)效(xiao)率(lv)。
2、低溫(wen)(wen)下對動(dong)(dong)力(li)電(dian)(dian)(dian)池(chi)進行直流充電(dian)(dian)(dian),電(dian)(dian)(dian)池(chi)控制器(qi)檢測動(dong)(dong)力(li)電(dian)(dian)(dian)池(chi)溫(wen)(wen)度,根據動(dong)(dong)力(li)電(dian)(dian)(dian)池(chi)溫(wen)(wen)度進行電(dian)(dian)(dian)池(chi)加(jia)熱(re)狀態判斷,當電(dian)(dian)(dian)池(chi)處于(yu)低溫(wen)(wen)禁(jin)止充電(dian)(dian)(dian)時,需先進入(ru)加(jia)熱(re)才(cai)能進行充電(dian)(dian)(dian),即先進入(ru)純(chun)(chun)加(jia)熱(re)模(mo)(mo)式。然而,現有的(de)技術方案在純(chun)(chun)加(jia)熱(re)模(mo)(mo)式下,由于(yu)整(zheng)車負載工況(kuang)的(de)變(bian)化及加(jia)熱(re)元件的(de)功率波動(dong)(dong),導(dao)致動(dong)(dong)力(li)電(dian)(dian)(dian)池(chi)存在誤充電(dian)(dian)(dian)或誤放電(dian)(dian)(dian)的(de)風險。
