Xa uhlawula ibhetri ye-lithium-ion, i-voltage yokutshaja kunye nokutshaja kufuneka ilawulwe ngokulandelelana kwexesha.Ngoko ke, umsebenzi wophando kwitshaja yebhetri ye-lithium-ion kufuneka iqhutywe ngokuthe ngcembe ngesiseko sokuqonda ngokucacileyo ukutshaja kwayo kunye nokukhupha iimpawu, oko kukuthi, izinto eziphambili ezichaphazela ukusebenza kokutshaja kweebhetri ze-lithium-ion: i-voltage kunye nekhoyo.
1. Umbane.I-voltage yegama leebhetri ze-lithium-ion ngokubanzi i-3.6V okanye i-3.7V (kuxhomekeke kumenzi).Amandla ombane okuphelisa intlawulo (ekwabizwa ngokuba yi-voltage edadayo okanye ivoltheji edadayo) ngokubanzi yi-4.1V, 4.2V, njl., kuxhomekeke kwisixhobo esithile se-electrode.Ngokuqhelekileyo, i-voltage yokuphelisa yi-4.2V xa izinto ze-electrode ezingalunganga ziyigraphite, kwaye i-voltage yokuphelisa yi-4.1V xa i-electrode engafanelekanga i-carbon.Kwibhetri efanayo, nokuba i-voltage yokuqala iyahluka ngexesha lokutshaja, xa umthamo webhetri ufikelela kwi-100%, i-voltage yokugqibela iya kufikelela kwinqanaba elifanayo.Kwinkqubo yokutshaja ibhetri ye-lithium-ion, ukuba i-voltage iphezulu kakhulu, inani elikhulu lobushushu liya kuveliswa ngaphakathi kwebhetri, eliya konakalisa isakhiwo se-electrode esihle sebhetri okanye kubangele isiphaluka esifutshane.Ngoko ke, kuyimfuneko ukubeka iliso kwi-voltage yokutshaja yebhetri ngexesha lokusetyenziswa kwebhetri ukulawula i-voltage ngaphakathi koluhlu oluvumelekileyo lombane.
2. Ngoku.Inkqubo yokutshaja idinga ukulawula ukutshaja okwangoku.Ukutshaja kwangoku kwebhetri kumiselwa bubungakanani bebhetri.Isimboli yomthamo wegama ngu-C, kwaye iyunithi ithi "Ah".Indlela yokubala yile: C = IT (1-1) Kwifomula, ndiyiyo yokukhutshwa kwangoku ngokuqhubekayo, kwaye i-T yithuba lokukhutshwa.Ngokomzekelo, ukuhlawula ibhetri ngomthamo we-50Ah nge-current ye-50A, kuthatha iyure ye-1 ukuhlawula ngokupheleleyo ibhetri.Ngeli xesha, izinga lokutshaja ngu-1C, kwaye izinga lokutshaja elisetyenziswa ngokuqhelekileyo liphakathi kwe-0.1C kunye ne-1C.Ngokubanzi, inkqubo yokutshaja yohlulwe ngokweendidi ezintathu: ukutshaja okucothayo (okukwabizwa ngokuba kukutshaja okuncinci), ukutshaja okukhawulezayo kunye nesantya esiphezulu sokutshaja ngokwemilinganiselo yokutshaja eyahlukileyo.Ukutshaja okucothayo okwangoku kuphakathi kwe-0.1C kunye ne-0.2C;umjelo wokutshaja wokutshaja ngokukhawuleza mkhulu kune-0.2C kodwa ngaphantsi kwe-0.8C;umsinga wokutshaja we-ultra-fast chaging mkhulu kuno-0.8C.Ekubeni ibhetri inokuchasana okuthile kwangaphakathi, ukufudumeza kwayo kwangaphakathi kuhambelana nokukhoyo.Xa ukusebenza kwangoku kwebhetri kukhulu kakhulu, ukushisa kwayo kuya kubangela ukunyuka kweqondo lokushisa kwebhetri kudlule ixabiso eliqhelekileyo, eliya kuchaphazela ukhuseleko lwebhetri kwaye lubangele ukuqhuma.Kwinqanaba lokuqala lokutshaja, nokuba ibhetri ikhutshwe kakhulu, ayinakuhlawuliswa ngokuthe ngqo ngokukhoyo okukhulu.Kwaye njengoko kuqhubeka ukutshaja, ukukwazi kwebhetri ukwamkela okwangoku kuyancitshiswa.Ngoko ke, kwinkqubo yokutshaja ibhetri, umbane wokutshaja kufuneka ulawulwe ngokwemeko ethile yebhetri.
