Musa ukuhlawulisa kubushushu obuphantsi

Ebusika, abasebenzisi beemoto zombane baneemvakalelo ezicacileyo zokuba ubomi bebhetri bufutshane! Kutheni kunje?

Kwiibhetri ze-lithium, akukho theory ecacileyo yokuxhasa ukuchasana kwangaphakathi, iqonga lokukhutshwa, ubomi kunye nomthamo weebhetri ze-lithium kumaqondo okushisa ahlukeneyo. Iifomula zokubala ezinxulumeneyo kunye neemodeli zemathematika zisekwinqanaba lophononongo. Ngokuqhelekileyo, iibhetri ze-lithium azikhathaleli kwiqondo lokushisa kwi-0-40 ° C, kodwa ngaphaya kolu luhlu, ubomi babo kunye namandla abo buya kuncipha.

Ekubeni ukuhamba okuphezulu kunye nokuhambelana kweebhetri ze-lithium nazo ziyingxaki enkulu, umxholo othile awukwazi ukumiselwa. Nokuba ibhetshi efanayo yeemveliso, idatha efanayo, kunye nenkqubo efanayo inemisebenzi eyahlukileyo kakhulu.

Emva kweemvavanyo ezininzi, ukusebenza kweqondo lokushisa eliphantsi kweebhetri ze-lithium phantsi kwedatha eyahlukeneyo kwahlukile. Ngoku eyona ishushu i-lithium iron phosphate inowona msebenzi uphantsi wobushushu obuphantsi. Umthamo wokukhutshwa kweemveliso zethu kwi–10 ° C yi-89% yomthamo omkhulu wokukhululwa, omele ube phezulu kwishishini. Kwi-55 ° C, umthamo wokukhupha unokufikelela kwi-95%, kwaye ukuthotywa kusencinci kakhulu kumaqondo aphantsi. Le iseyimveliso eza kuvavanywa. Uyazi, umgangatho wayo uphezulu kakhulu kuneemveliso eziqhelekileyo kumgca wokuhlanganisa.

Ngokwahlukileyo, i-lithium manganese, i-lithium cobalt kunye neemveliso ze-ternary zinemisebenzi engcono yokushisa ephantsi, kodwa nazo zinemida. Umbingelelo ngumsebenzi wobushushu obuphezulu. Okwangoku, umsebenzi wokhuseleko we-lithium iron phosphate ovuthwe kwimizi-mveliso uphezulu kakhulu, kwaye umsebenzi wobushushu obuphezulu nawo ulungile. Enyanisweni, umsebenzi webhetri awukho phezulu njengeentlobo ezintathu ezingentla, kwaye zikhuselekile. Umsebenzi uwonke awukalunganga njengemanganese, i-lithium okanye i-ternary.

Ngoko ke, abanye abantu bakhalaza ukuba iibhetri ze-lithium azikwazi ukuhlawuliswa ebusika. Inxalenye yesizathu sokuba basebenzise ulawulo lwebhetri kukuba imveliso ikhuselwe. Ubomi benkonzo yeebhetri ze-lithium ebusika ngokuqinisekileyo buya kuba bufutshane kunehlobo. Apha ukukhumbuza wonke umntu ukuba kungcono ukuba ungahlawulisi iibhetri ze-lithium ebusika. Ngenxa yokushisa okuphantsi, i-lithium ion iya kukhanya kwi-electrode engalunganga, idlule ngokuthe ngqo kwi-gap, kwaye ngokubanzi yenze isiphaluka esifutshane esincinci, esichaphazela ubomi benkonzo kunye nomsebenzi, kwaye inokuqhuma kwiimeko ezinzulu!
