Amabhethri ambalwa e-lithium angaxhunywa ochungechungeni ukwakha iphakethe lebhethri, elinganikeza amandla emithanjeni ehlukahlukene futhi angakhokhiswa ngokujwayelekile ngeshaja ehambelana. Amabhethri e-lithium awadingi noma yiluphi uhlelo lokuphatha ibhethri (I-BMS) ukukhokhisa nokukhipha. Manje kungani wonke amabhethri e-lithium emakethe engeza i-BMS? Impendulo ingukuphepha nokuphila isikhathi eside.
Uhlelo lokuphatha ibhethri (uhlelo lokuphathwa kwebhethri) lusetshenziselwa ukuqapha nokulawula ukushaja kanye nokukhipha amabhethri atholakala kabusha. Umsebenzi obaluleke kakhulu wohlelo lokuphathwa kwebhethri lwe-lithium (BMS) ukuqinisekisa ukuthi amabhethri ahlala ngaphakathi kwemingcele yokusebenza ephephile futhi athathe izinyathelo ezisheshayo uma ngabe kukhona ibhethri ngalinye liqala ukudlula imikhawulo. Uma i-BMS ithola ukuthi i-voltage iphansi kakhulu, izoyinqamula umthwalo, futhi uma ivola liphezulu kakhulu, lizonqamula ishaja. Izobheka nokuthi iseli ngalinye ephaketheni liku-voltage linye futhi linciphise noma yiliphi ivolumenti eliphakeme kunamanye amaseli. Lokhu kuqinisekisa ukuthi ibhethri alifinyeleli ama-voltages aphezulu noma aphansi-Okuvame ukuba yimbangela yemililo yebhethri le-lithium esikubonayo ezindabeni. Ingabheka ngisho nezinga lokushisa lebhethri bese lixhuma iphakethe lebhethri ngaphambi kokuba lishise kakhulu ukuba libambe umlilo. Ngakho-ke, i-BMS yokuphatha ibhethri ivumela ibhethri ukuthi livikelwe kunokuba lincike ekunciphiseni ishaja noma umsebenzi womsebenzisi ofanele.
Kungani ungavumi't Holid-acid amabhethri adinga uhlelo lokuphatha ibhethri? Ukwakheka kwamabhethri we-lead-acid akunakuvutha kancane, okwenza kube mancane amathuba okuthi babambe umlilo uma kunenkinga yokushaja noma ngokukhipha. Kepha isizathu esiyinhloko kufanele senze nokuthi ibhethri liziphatha kanjani lapho likhokhiswa ngokuphelele. Amabhethri e-lead-acid nawo akhiwa amaseli axhunyiwe ochungechungeni; Uma iseli elilodwa linenkokhiso ethe xaxa kunamanye amaseli, lizovumela kuphela ukudlula kwamanje kuze kube yilapho amanye amaseli ekhokhiswe ngokuphelele, ngenkathi egcina i-voltage enengqondo, njll. Amaseli athola. Ngale ndlela, amabhethri e-lead-acid "alinganisele" njengoba bekhokhisa.
Amabhethri e-Lithium ahlukile. I-electrode enhle yamabhethri e-lithium aphindaphindwayo yi-lithium ion impahla. Umgomo wayo wokusebenza unquma ukuthi ngesikhathi sokushaja kanye nenqubo yokukhipha imali, ama-lithium electron azogijimela ezinhlangothini zombili ze-electrodes ezinhle nezingalungile kaninginingi. Uma ugesi weseli elilodwa evunyelwe ukuba abe ngaphezulu kuka-4.25v (ngaphandle kwamabhethri e-lithium aphezulu aphezulu), isakhiwo se-anode i-microporous singakhula, khona-ke izinto ezinzima zizokhula zibangele umjikelezo omfushane, ekugcineni izinga lokushisa livuke. Lapho ibhethri le-lithium likhokhiswa ngokuphelele, amavota akhuphuka ngokuzumayo futhi angafinyelela ngokushesha amazinga ayingozi. Uma uVoltage weseli elithile ephaketheni lebhethri liphakeme kunalelo amaseli, leli seli lizofinyelela ku-voltage eyingozi kuqala ngesikhathi senqubo yokushaja. Ngalesi sikhathi, i-voltage ephelele yephakethe lebhethri ayikafinyeleli inani eliphelele, bese ishaja ngeke iyeke ukushaja. . Ngakho-ke, amaseli afinyelela amavoluti ayingozi kuqala azodala ubungozi bokuphepha. Ngakho-ke, ukulawula nokubheka inani eliphelele le-voltage yephakethe lebhethri akwanele kuma-lithium-based marleristries. I-BMS kumele ihlole i-voltage yeseli ngalinye elenziwa iphakethe lebhethri.
Ngakho-ke, ukuqinisekisa impilo ye-Lithium Battery yamaphakethe we-Lithium, ikhwalithi nohlelo lokuphathwa kwebhethri oluthembekile luyadingeka ngempela.
