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 yendawo yokulawula i-float charge: Ngokuqhelekileyo, emva kokuba intlawulo yokulinganisa igqityiwe, ibhetri nayo ishiywe ukuba ime ixesha elithile, ukwenzela ukuba i-terminal voltage yehle ngokwemvelo, kwaye xa ihla ukuya kwindawo "yesondlo sombane", ingena kwimo yentlawulo yokudada.Okwangoku, iPWM iyasetyenziswa.(zombini ukumodareyitha kobubanzi be-pulse) indlela, ifana “nokutshaja okuncinci” (oko kukuthi, ukutshaja okuncinci kwangoku), tshaja kancinane xa amandla ombane ebhetri ephantsi, kwaye uhlawule kancinci xa uphantsi, nganye nganye ukunqanda ubushushu bebhetri ukusuka ukuqhubeka nokunyuka Phezulu, okulungileyo 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 ngokufanelekileyo kwindawo yokukhusela i-voltage ye-12V yebhetri njengembuyekezo yeqondo lokushisa okanye ukulungiswa kwe-0. I-voltage yendawo yokukhusela yebhetri ye-12V yile: 11.10v, emva koko I-voltage yokukhusela i-over-discharge point ye-24V system yi-22.20V.
