1. I-voltage yendawo yokuvikela eshaja eqondile: Ukushaja okuqondile kubuye kubizwe ngokuthi inkokhiso ephuthumayo, okungeyenkokhelo esheshayo.Ngokuvamile, lapho i-voltage yebhethri iphansi, ibhethri lishajwa ngamandla amanje aphezulu kanye ne-voltage ephezulu uma kuqhathaniswa.Kodwa-ke, kukhona indawo yokulawula, ebizwa nangokuthi ukuvikela Iphuzu liyinani elikuthebula elingenhla.Uma i-voltage yetheminali yebhethri iphakeme kunalawa manani okuvikela ngesikhathi sokushajwa, ukushajwa okuqondile kufanele kumiswe.Ivolthi yephoyinti yokuvikela ukushajwa okuqondile ngokuvamile iphinde ibe “iphoyinti lokuvikela ukushajwa ngokweqile”, futhi i-voltage yetheminali yebhethri ayikwazi ukuba phezulu kunaleli phuzu lokuvikela ngesikhathi sokushajwa, ngaphandle kwalokho izobangela ukushajwa ngokweqile futhi ilimaze ibhethri.
2. I-voltage yephoyinti yokulawula ukushajwa kokulinganisa: Ngemva kokuqedwa kokushajwa okuqondile, ibhethri ngokuvamile lizoshiywa isikhathi esithile yisilawuli sokushajwa ukuze kuvumeleke ukuthi i-voltage yayo yehle ngokwemvelo.Uma yehla kunani "lokubuyisela amandla", izongena esimweni sokushaja sokulinganisa.Kungani uklama inkokhiso elinganayo?Okusho ukuthi, ngemva kokuqedwa kokushaja okuqondile, kungase kube khona amabhethri ngamanye "asalele ngemuva" (i-voltage yokugcina iphansi kakhulu).Ukuze ubuyisele la ma-molecule ngamanye futhi wenze wonke ama-voltage etheminali yebhethri afane, kuyadingeka ukufanisa amandla kagesi aphezulu ne-voltage emaphakathi.Bese uyikhokhisa isikhathi esifushane, kungabonakala ukuthi inkokhiso ebizwa ngokuthi yi-equalization charge, okungukuthi, “i-balanced charge”.Isikhathi sokushaja sokulinganisa akufanele sibe side kakhulu, ngokuvamile imizuzu embalwa ukuya emaminithini ayishumi, uma isilungiselelo sesikhathi siside kakhulu, sizoba yingozi.Ohlelweni oluncane olufakwe ibhethri elilodwa noma amabili, ukushaja okulinganayo akusho lutho.Ngakho-ke, izilawuli zezibani zomgwaqo ngokuvamile azinakho ukushaja okulinganayo, kodwa izigaba ezimbili kuphela.
3. I-voltage yephoyinti lokulawula ukushaja okuntantayo: Ngokuvamile, ngemva kokuqedwa kokukhokhiswa kokulinganisa, ibhethri nayo iyekwa ukuthi ime isikhathi esithile, ukuze i-terminal voltage yehle ngokwemvelo, futhi lapho yehlela endaweni “ye-voltage yesondlo”, ingena esimweni sokushaja okuntantayo.Njengamanje, i-PWM isetshenziswa.(kokubili ukuguquguquka kobubanzi be-pulse) indlela, efana “nokushaja okukhohlisayo” (okungukuthi, ukushaja okuncane kwamanje), shaja kancane lapho i-voltage yebhethri iphansi, futhi ishaje kancane uma iphansi, ngayinye ngayinye ukuvimbela izinga lokushisa lebhethri lisuka ekuqhubekeni likhuphuka Liphezulu, okuyinto enhle kakhulu ebhethrini, ngoba izinga lokushisa langaphakathi lebhethri linethonya elikhulu ekushajeni nasekuyikhipheni.Eqinisweni, indlela ye-PWM iklanyelwe kakhulu ukuzinzisa i-voltage yetheminali yebhethri, nokunciphisa amandla amanje ashaja ibhethri ngokulungisa ububanzi be-pulse.Lolu uhlelo lokuphatha ukushaja olungokwesayensi.Ngokukhethekile, esigabeni sakamuva sokushaja, lapho umthamo osele (i-SOC) webhethri ungaphezulu kwama-80%, umthamo wokushaja kufanele wehliswe ukuze kuvinjwe ukuphuma komoya ngokweqile (umoya-mpilo, i-hydrogen ne-asidi) ngenxa yokushajwa ngokweqile.
4. I-voltage yokunqamula yokuvikela ukukhishwa ngokweqile: Lokhu kulula ukukuqonda.Ukukhishwa kwebhethri akukwazi ukuba ngaphansi kwaleli nani, okuyindinganiso kazwelonke.Nakuba abakhiqizi bebhethri nabo benemingcele yabo yokuvikela (izinga lebhizinisi noma izinga lemboni), kusafanele basondele ezingeni likazwelonke ekugcineni.Kufanele kuqashelwe ukuthi, ngenxa yokuphepha, ngokuvamile i-0.3v yengezwa ngokungemthetho endaweni kagesi yokuvikela ukukhishwa ngokweqile kwebhethri engu-12V njengesinxephezelo sezinga lokushisa noma ukulungiswa kwe-zero-point drift yesekethe yokulawula, ukuze ukuchithwa ngokweqile. I-protective point voltage yebhethri engu-12V ithi: 11.10v, bese kuthi I-voltage yendawo yokuvikela yokukhipha ngokweqile yesistimu engu-24V ingu-22.20V.
