Uma kuziwa ekukhetheni ibhethri elifanele lezidingo zakho, ukuqonda umehluko phakathi kwamabhethri e-lithium, ikakhulukazi i-LiFePO4, namabhethri e-lead-acid kubalulekile. Izici zabo ezihlukile zibenza bafanelekele izimo ezihlukene.
Ibhethri ye-Lithium (LiFePO4) : Amabhethri e-lithium iron phosphate adume ngokuminyana kwawo okuphezulu nokuphila isikhathi eside. Imvamisa, ibhethri le-LiFePO4 lizidla impilo yomjikelezo efinyelela kumjikelezo we-2000. Lokhu kusho ukuthi ingashajwa futhi ikhishwe izikhathi eziningi ngaphambi kokuba umthamo wayo wehle kakhulu. Amandla azo ahlala engaguquki isikhathi eside, okuwenza alungele izinhlelo zokusebenza ezidinga umthombo wamandla othembekile nohlala isikhathi eside.
Ibhethri Le-Acid Yomthofu : Ngokuphambene, amabhethri e-lead-asidi anempilo yomjikelezo omfushane, ngokuvamile phakathi kwemijikelezo engu-300 kuya ku-500. Nakuba zibiza kancane ngaphambili, amandla azo avame ukwehla ngokushesha ngomjikelezo ngamunye. Lesi sici sizenza zingalungeli kakhulu izinhlelo zokusebenza ezifuna ukukhishwa okujulile okuvamisile kanye nokushajwa kabusha.
Amandla Aqhubekayo : Ubudlelwano phakathi kwe-voltage ne-SOC (State of Charge) buncike ngokuqondile ohlotsheni lwebhethri elisetshenziswayo. Amabhethri e-LiFePO4 aletha i-voltage ezinzile kuwo wonke umjikelezo wawo wokuphuma, ehlinzeka ngokuphuma kwamandla okungaguquki. Amabhethri e-lead-acid, nokho, aba nokwehla kancane kancane kwe-voltage njengoba ephuma, okungase kuthinte ukusebenza kwamadivayisi awanika amandla.
Ukusebenza Kwezinga Lokushisa : Amabhethri e-lithium ahamba phambili ngebanga elibanzi lokushisa. Abajwayele ukuwohloka emazingeni okushisa aphezulu uma kuqhathaniswa namabhethri aneasidi yomthofu, angase ahlupheke ngenxa yokuncipha kokusebenza kahle kanye neminyaka yokuphila ezimweni ezinjalo.
Isisindo : Amabhethri e-LiFePO4 alula kakhulu kunamabhethri e-lead-acid, ngokuvamile anesisindo esingaphansi kuka-50-70%. Le nzuzo yesisindo yenza kube lula ukuphatha nokufaka.
Isitoreji : Amabhethri e-lithium anenani eliphansi lokuzikhulula, okusho ukuthi agcina ukushajwa kwawo isikhathi eside uma engasetshenziswa. Amabhethri aneasidi yomthofu, nokho, anezinga eliphezulu lokuzikhulula futhi adinga ukunakekelwa okuvamile ukuze agcinwe esebenza.
Isiqondiso Sokufaka : Amabhethri e-LiFePO4 angafakwa kunoma yikuphi ukuma ngaphandle kwengozi yokuvuza, anikeze ukuguquguquka okukhulu ekuklanyweni nasekubekeni. Amabhethri aneasidi yomthofu, ngenxa yokukhishwa kwegesi eyinsalela, adinga ukufakwa aqonde ukuvimbela noma yiziphi izinkinga ezingaba khona zokuphuma umoya.
Uchungechunge Noxhumano Oluhambisanayo : Zombili izinhlobo zebhethri zingaxhunywa ochungechungeni nokuhambisana ukuze kuzuzwe i-voltage nomthamo oyifunayo. Kodwa-ke, amabhethri avamile we-Lifepo4 kanye ne-lead-acid awakwazi ukusetshenziswa ngokuhambisana ochungechungeni olufanayo.
Ngokusetshenziswa okuxubile, Ibhethri le-DFUN SmartLi liyanconywa. Umkhiqizo usetshenziswa kakhulu njengamandla okulondoloza izingosi zokuxhumana ngocingo. Ngohlelo olwakhelwe ngaphakathi oluhlakaniphile Lokuqapha Ibhethri (i-BMS) kanye nesiguquli se-DC/DC esinezinhlangothi ezimbili, ingahlanganisa ngokuqondile ukusetshenziswa nebhethri le-lead-acid ngokuhambisana ukuze ibone ukusetshenziswa kabusha nokunwetshwa kwamabhethri akhona, ukuze inikeze amandla ayisipele azinzile wezinhlelo zokusebenza ezifana nesiteshi se-Telecom, Uloliwe, Isiteshi esincane njll.
