Lapho ushaja ibhethri le-lithium-ion, i-voltage yokushaja yamanje neyokushaja kufanele ilawulwe ngokuvumelana nokulandelana kwesikhathi.Ngakho-ke, umsebenzi wocwaningo kushaja yebhethri ye-lithium-ion yamandla kufanele wenziwe kancane kancane ngesisekelo sokuqonda ngokucacile izici zayo zokushaja nokukhipha, okungukuthi, izici eziyinhloko ezithinta ukusebenza kokushaja kwamabhethri e-lithium-ion: i-voltage kanye namanje.
1. Amandla kagesi.Amandla kagesi e-lithium-ion ngokuvamile angu-3.6V noma angu-3.7V (kuye ngokuthi umenzi).I-voltage yokunqamula ukushaja (ebuye ibizwe ngokuthi i-voltage elintantayo noma i-voltage entantayo) ivamise ukuba ngu-4.1V, 4.2V, njll., kuye ngento ethile ye-electrode.Ngokuvamile, i-voltage yokunqamula ingu-4.2V lapho impahla ye-electrode eyinegethivu iyigraphite, futhi i-voltage yokunqamula ingu-4.1V lapho into engalungile ye-electrode kuyikhabhoni.Ngebhethri elifanayo, noma ngabe i-voltage yokuqala ihlukile ngesikhathi sokushaja, lapho umthamo webhethri ufinyelela ku-100%, i-voltage yokugcina izofinyelela ezingeni elifanayo.Enqubweni yokushaja ibhethri ye-lithium-ion, uma i-voltage iphezulu kakhulu, inani elikhulu lokushisa lizokhiqizwa ngaphakathi kwebhethri, elizolimaza isakhiwo se-electrode esihle sebhethri noma kubangele isifunda esifushane.Ngakho-ke, kuyadingeka ukuqapha i-voltage yokushaja yebhethri ngesikhathi kusetshenziswa ibhethri ukuze ulawule i-voltage ngaphakathi kwebanga le-voltage elivumelekile.
2. Okwamanje.Inqubo yokushaja idinga ukulawula ukushaja kwamanje.Ukushaja kwamanje kwebhethri kunqunywa umthamo webhethri.Uphawu lomthamo othize ngu-C, kanti iyunithi ithi “Ah”.Indlela yokubala ithi: C = IT (1-1) Kufomula, mina ngingumshini wamanje wokukhipha oqhubekayo, kanti u-T yisikhathi sokukhipha.Isibonelo, ukushaja ibhethri elinomthamo we-50Ah nge-current ye-50A, kuthatha ihora elingu-1 ukushaja ngokugcwele ibhethri.Ngalesi sikhathi, izinga lokushaja lingu-1C, futhi izinga lokushaja elivame ukusetshenziswa liphakathi kuka-0.1C no-1C.Ngokuvamile, inqubo yokushaja ihlukaniswe yaba izinhlobo ezintathu: ukushaja okunensayo (okubuye kubizwe ngokuthi ukushaja okukhohlisayo), ukushaja okusheshayo kanye nokushaja okunesivinini esikhulu ngokuya ngezilinganiso zokushaja ezihlukene.Ukushaja okunensayo kwamanje kuphakathi kuka-0.1C no-0.2C;umthamo wokushaja wokushaja okusheshayo mkhulu kuno-0.2C kodwa ungaphansi kuka-0.8C;umthamo wokushaja wokushaja oshesha kakhulu mkhulu kuno-0.8C.Njengoba ibhethri inokumelana okuthile kwangaphakathi, ukushisa kwayo kwangaphakathi kuhlobene namanje.Uma ukusebenza kwamanje kwebhethri kukukhulu kakhulu, ukushisa kwayo kuzobangela ukunyuka kwezinga lokushisa kwebhethri kudlule inani elivamile, okuzothinta ukuphepha kwebhethri futhi kubangele nokuqhuma.Esigabeni sokuqala sokushaja, ngisho noma ibhethri liphume lijule kakhulu, alikwazi ukushajwa ngokuqondile ngomsinga omkhulu.Futhi njengoba ukushajwa kuqhubeka, amandla ebhethri okwamukela ukusebenza kwawo ayancishiswa.Ngakho-ke, ohlelweni lokushaja ibhethri, amandla okushaja kufanele alawulwe ngokuya ngesimo esithile sebhethri.
