Amabhethri e-lithium amaningana angaxhunywa ochungechungeni ukuze akhe iphakethe lebhethri, elinganikeza amandla emithwalweni ehlukahlukene futhi lingashajwa ngokuvamile ngeshaja efanayo.Amabhethri e-lithium awadingi noma yiluphi uhlelo lokuphatha ibhethri (I-BMS) ukushaja nokukhipha.Pho kungani wonke amabhethri e-lithium emakethe engeza i-BMS?Impendulo iwukuphepha nokuphila isikhathi eside.
Isistimu yokuphatha ibhethri i-BMS (Isistimu Yokulawula Ibhethri) isetshenziselwa ukuqapha nokulawula ukushajwa nokushajwa kwamabhethri aphinde ashajwe.Umsebenzi obaluleke kakhulu wesistimu yokulawula ibhethri ye-lithium (BMS) ukuqinisekisa ukuthi amabhethri ahlala ngaphakathi kwemikhawulo yokusebenza ephephile kanye nokuthatha isinyathelo esisheshayo uma ibhethri ngalinye liqala ukweqa imikhawulo.Uma i-BMS ithola ukuthi i-voltage iphansi kakhulu, izonqamula umthwalo, futhi uma i-voltage iphezulu kakhulu, izonqamula ishaja.Izophinde ihlole ukuthi iseli ngalinye ephaketheni liku-voltage efanayo futhi inciphise noma iyiphi i-voltage ephakeme kunamanye amaseli.Lokhu kuqinisekisa ukuthi ibhethri ayifinyeleli kuma-voltage aphezulu noma aphansi ngokuyingozi-okuvame ukuba yimbangela yokusha kwebhethri ye-lithium esiyibona ezindabeni.Ingakwazi ngisho nokugada izinga lokushisa lebhethri futhi inqamule iphakethe lebhethri ngaphambi kokuthi lishise kakhulu ukuthi libambe umlilo.Ngakho-ke, isistimu yokuphatha ibhethri ye-BMS ivumela ibhethri ukuthi livikelwe kunokuthembela eshajani enhle noma ekusebenzeni komsebenzisi okulungile.
Kungani ungathandi't amabhethri e-lead-acid adinga uhlelo lokuphatha ibhethri?Ukwakheka kwamabhethri aneasidi yomthofu akuvuthi kangako, kuwenza mancane amathuba okuthi abambe umlilo uma kunenkinga ngokushaja noma ukushajwa.Kodwa isizathu esikhulu sihlobene nendlela ibhethri eliziphatha ngayo uma selishajwe ngokugcwele.Amabhethri e-lead-acid nawo akhiwe ngamaseli axhunywe ochungechungeni;uma iseli elilodwa linokushajwa okuthe xaxa kunamanye amaseli, lizovumela kuphela ukudlula kwamanje kuze kube yilapho amanye amaseli eseshajwe ngokugcwele, kuyilapho igcina i-voltage enengqondo, njll. Amaseli abamba phezulu.Ngale ndlela, amabhethri e-lead-acid "azibhalansi" njengoba eshajwa.
Amabhethri e-lithium ahlukile.I-electrode ekhangayo yamabhethri e-lithium aphinde ashajwe ngokuvamile i-lithium ion material.Umgomo wayo wokusebenza unquma ukuthi phakathi nenqubo yokushaja nokukhipha, ama-electron e-lithium azogijima ezinhlangothini zombili zama-electrode aqondile noma angalungile kaninginingi.Uma i-voltage yeseli eyodwa ivunyelwe ukuba ibe ngaphezu kwe-4.25v (ngaphandle kwamabhethri e-lithium aphezulu-voltage), isakhiwo se-anode microporous singase siwohloke, i-crystal material eqinile ingase ikhule futhi ibangele isifunda esifushane, bese izinga lokushisa lizokhuphuka. ngokushesha, ekugcineni kuholele emlilweni.Uma ibhethri ye-lithium ishajwe ngokugcwele, i-voltage ikhuphuka ngokuzumayo futhi ingafinyelela ngokushesha emazingeni ayingozi.Uma i-voltage yeseli ethile ephaketheni lebhethri ingaphezulu kweyamanye amaseli, leli seli lizofinyelela kugesi oyingozi kuqala phakathi nenqubo yokushaja.Ngalesi sikhathi, i-voltage iyonke yephakethe lebhethri ayikakafiki inani eligcwele, futhi ishaja ngeke iyeke ukushaja..Ngakho-ke, amaseli afinyelela ama-voltage ayingozi kuqala azodala izingozi zokuphepha.Ngakho-ke, ukulawula nokuqapha ingqikithi yamandla kagesi wephakethe lebhethri akwanele kumakhemistri asuselwa ku-lithium.I-BMS kufanele ihlole i-voltage yeseli ngayinye eyakha iphakethe lebhethri.
Ngakho-ke, ukuqinisekisa ukuphepha nempilo ende yesevisi yamaphakethe ebhethri ye-lithium, isistimu yokuphatha ibhethri yekhwalithi nethembekile iyadingeka ngempela.
