1. I-voltage yendawo yokukhusela ngokuthe ngqo: Intlawulo ethe ngqo ikwabizwa ngokuba yintlawulo kaxakeka, eyeyentlawulo ekhawulezayo. Ngokuqhelekileyo, xa amandla ombane ebhetri ephantsi, ibhetri ihlawuliswa ngokuphezulu kwangoku kunye nombane ophezulu. Nangona kunjalo, kukho indawo yokulawula, ebizwa ngokuba ngukhuseleko Inqaku lixabiso kwitheyibhile engentla. Xa i-terminal voltage iphezulu kunala maxabiso okhuseleko ngexesha lokutshaja, ukutshaja ngokuthe ngqo kufuneka kuyekwe. I-voltage yendawo yokukhusela ngokuthe ngqo ngokuqhelekileyo ikwayi-voltage "yokukhusela i-overcharge", kwaye i-voltage ye-terminal yebhetri ayikwazi ukuba phezulu kunendawo yokukhusela ngexesha lokutshaja, ngaphandle koko iya kubangela ukutshaja kwaye yonakalise ibhetri.
2. Ukulinganisa i-voltage yokulawula i-voltage yokulinganisa: Emva kokuba intlawulo ethe ngqo igqityiwe, ibhetri iya kushiywa ngokubanzi ixesha elithile ngumlawuli we-charge-discharge ukuvumela ukuba i-voltage yayo yehle ngokwemvelo. Xa ihla kwixabiso "lokubuyisela i-voltage", liya kungena kwi-equalization charge state. Kutheni uyila intlawulo elinganayo? Oko kukuthi, emva kokuba ukutshaja ngokuthe ngqo kugqitywe, kunokubakho iibhetri zomntu ngamnye "ushiye ngasemva" (i-terminal voltage iphantsi). Ukuze utsale ezi molekyuli zodwa kwaye wenze zonke ii-voltages ze-terminal yebhetri zifanane, kuyimfuneko ukutshatisa amandla ombane aphezulu kunye nombane ophakathi. Emva koko uhlawule ixesha elifutshane, kunokubonwa ukuba into ebizwa ngokuba yi-equalization charge, oko kukuthi, "intlawulo elinganayo". Ixesha lokuhlawula ukulinganisa akufanele libe lide kakhulu, ngokuqhelekileyo imizuzu embalwa ukuya kwimizuzu elishumi, ukuba ixesha lokumisela ixesha lide kakhulu, liya kuba yingozi. Kwisixokelelwano esincinci esixhotyiswe ngebhetri enye okanye ezimbini, ukutshaja ngokulinganayo akubalulekanga kangako. Ngoko ke, abalawuli bokukhanya kwesitrato ngokubanzi abanalo ukutshaja okulinganayo, kodwa izigaba ezimbini kuphela.
3. I-voltage ye-float charge control point: Ngokuqhelekileyo, emva kokuba intlawulo yokulinganisa igqityiwe, ibhetri ibuye ishiywe ukuba ime ixesha elithile, ukwenzela ukuba i-terminal voltage yehle ngokwemvelo, kwaye xa ihla "kwindawo yokugcina i-voltage", ingena kwi-float charge state. Okwangoku, iPWM iyasetyenziswa. (zombini i-pulse width modulation) indlela, efana ne "trickle charging" (oko kukuthi, ukutshaja okuncinci kwangoku), hlawulisa kancinci xa amandla ombane ebhetri ephantsi, kwaye uhlawule kancinci xa uphantsi, enye nenye ukuthintela ubushushu bebhetri ukuba buqhubeke bunyuka Phezulu, oko kulunge kakhulu kwibhetri, kuba ubushushu bangaphakathi bebhetri bunempembelelo enkulu ekutshajisweni nasekukhupheni. Ngapha koko, indlela ye-PWM yenzelwe ukuzinzisa i-voltage ye-terminal yebhetri, kunye nokunciphisa ibhetri yokutshaja ngoku ngokuhlengahlengisa ububanzi be-pulse. Le yinkqubo yolawulo lokutshaja ngokwenzululwazi kakhulu. Ngokukodwa, kwinqanaba lokugqibela lokutshaja, xa umthamo oseleyo (i-SOC) webhetri u> 80%, umbane wokutshaja kufuneka uncitshiswe ukuthintela ukuphuma okugqithisileyo (i-oksijeni, i-hydrogen kunye negesi ye-asidi) ngenxa yokutshaja.
4. Ukupheliswa kombane wokhuseleko lokukhupha ngaphezulu: Oku kulula ukukuqonda. Ukukhutshwa kwebhetri akunakuba ngaphantsi kweli xabiso, elisemgangathweni kazwelonke. Nangona abavelisi beebhetri nabo banemilinganiselo yabo yokukhusela (umgangatho weshishini okanye umgangatho woshishino), kusafuneka basondele kumgangatho wesizwe ekugqibeleni. Kufuneka kuqatshelwe ukuba, ngenxa yokhuseleko, ngokubanzi i-0.3v yongezwa ngokungekho mthethweni kwindawo yokukhusela i-voltage ye-12V yebhetri njengembuyekezo yobushushu okanye ukulungiswa kwe-zero-point drift yesekethe yolawulo, ukwenzela ukuba indawo yokukhusela i-over-discharge point voltage ye-12V yebhetri yile: 11.10v ye-voltage ye-voltage ye-2V yokukhusela i-2V yenkqubo yokukhusela i-2V, emva koko 22.20V.
