Amabhethri e-lithium-ion athandwa ngenxa yokuminyana kwawo okuphezulu kwamandla, impilo yomjikelezo omude, nezinga eliphansi lokuzikhipha. Ukuqonda ukuthi la mabhethri asebenza kanjani kubalulekile.
Izingxenye eziyisisekelo zebhethri ye-lithium-ion zifaka i-anode, i-cathode, i-electrolyte, nesihlukanisi. Lezi zakhi zisebenza ndawonye ukuze zigcine futhi zikhiphe amandla ngendlela efanele. I-anode ngokuvamile yenziwe nge-graphite, kuyilapho i-cathode iqukethe i-lithium metal oxide. I-electrolyte iyisisombululo sikasawoti we-lithium ku-solvent ephilayo, futhi isihlukanisi siwulwelwesi oluncane oluvimbela izifunda ezimfushane ngokugcina i-anode ne-cathode ihlukene.
Le nqubo yokushaja eyinkimbinkimbi ibalulekile empilweni yebhethri. Isistimu yokuqapha ibhethri ye-DFUN ilandelela ngokunembile le nqubo, iqapha futhi irekhoda ukushajwa okuphelele nokukhipha isimo ukuze kuqinisekiswe ukuthi konke ukushajwa kuphephile futhi kusebenza kahle.
Izinqubo zokushaja nokukhipha amabhethri e-lithium-ion zibalulekile ekusebenzeni kwawo. Lezi zinqubo zibandakanya ukunyakaza kwe-lithium ion phakathi kwe-anode ne-cathode ngokusebenzisa i-electrolyte.
Lapho ibhethri ye-lithium-ion ishaja, ama-ion e-lithium asuka ku-cathode aye ku-anode. Lokhu kunyakaza kwenzeka ngoba umthombo wamandla kagesi wangaphandle, usebenzisa i-voltage kuwo wonke amatheminali ebhethri. Le voltage ishayela i-lithium ion ngokusebenzisa i-electrolyte futhi ingene ku-anode, lapho igcinwa khona. Inqubo yokushaja ingahlukaniswa ibe izigaba ezimbili eziyinhloko: isigaba samanje (CC) esingaguquki kanye nesigaba samandla kagesi (CV).
Phakathi nesigaba se-CC, ibhethri elisebenza ngokuzinzile linikezwa, okwenza i-voltage inyuke kancane kancane. Uma ibhethri selifinyelele umkhawulo wamandla kagesi aphezulu, ishaja ishintshela esigabeni se-CV. Kulesi sigaba, i-voltage ibanjwe njalo, futhi okwamanje iyancipha kancane kancane ize ifinyelele inani elincane. Kuleli qophelo, ibhethri selishajwe ngokugcwele.
Ukushaja ibhethri ye-lithium-ion kuhilela inqubo ehlehlayo, lapho i-lithium ion isuka ku-anode ibuyele ku-cathode. Uma ibhethri lixhumeke ocingweni, ucingo ludonsa amandla kagesi ebhethrini. Lokhu kubangela ukuthi ama-ion e-lithium ashiye i-anode futhi ahambe nge-electrolyte aye ku-cathode, akhiqize amandla kagesi anika amandla idivayisi.
Ukusabela kwamakhemikhali ngesikhathi sokukhishwa empeleni kuphambene nalokho ngesikhathi sokushaja. Ama-ion e-lithium ahlangana (faka) kumpahla ye-cathode, kuyilapho ama-electron egeleza kumjikelezo wangaphandle, enikeza amandla kudivayisi exhunyiwe.
Lokhu kusabela kugqamisa ukudluliswa kwama-ion e-lithium nokugeleza okuhambisanayo kwama-electron, okuyisisekelo ekusebenzeni kwebhethri.
Amabhethri e-lithium-ion aziwa ngezici zawo ezithile, njengokuminyana kwamandla aphezulu, ukuzikhipha okuphansi, nempilo yomjikelezo omude. Lezi zimpawu zizenza zilungele izinhlelo zokusebenza lapho amandla ahlala isikhathi eside edingeka. Amamethrikhi okhiye wokusebenza amaningana asetshenziselwa ukuhlola amabhethri e-lithium-ion:
Ukuminyana kwamandla: Ikala inani lamandla agcinwe ngevolumu noma isisindo esinikeziwe.
I-Cycle Life: Ibonisa inani lemijikelezo yokushajwa ibhethri elingangena kuyo ngaphambi kokuba umthamo walo wehle kakhulu.
I-C-rate: Ichaza izinga ibhethri eshajwa ngalo noma ekhishwa ngalo uma liqhathaniswa nomthamo walo omkhulu.
Impilo yomjikelezo webhethri ayilona inani elingashintshi; ukuphathwa kokukhipha imali ngesikhathi sokusetshenziswa kwangempela kuba nomthelela omkhulu kukho. Ngokusebenzisa ukuqapha kwesikhathi sangempela kanye nokuhlaziywa kwedatha, i I-DFUN BMS Cloud Platform ikusiza ukuthi unwebe impilo yesevisi yephakethe lakho lebhethri.
Ukuqapha imijikelezo yokushaja nokukhipha amabhethri e-lithium-ion kubalulekile ukuze kuqinisekiswe ukuphila nokuphepha kwawo isikhathi eside. Ukushajwa ngokweqile noma ukushajwa okujulile kungaholela ekulimaleni kwebhethri, ukuncipha kwamandla, ngisho nezingozi zokuphepha njengokubaleka kokushisa. Ukuqinisekisa ukusebenza okuphephile kwesikhathi eside kwamaphakethe ebhethri ye-lithium, ukuqapha okuchwepheshile kubalulekile. Thola ukuthi kanjani I-DFUN Battery Monitoring System ihlinzeka ngokuvikeleka okungu-24/7 kumaphakethe akho ebhethri.
I-DFUN ihlinzeka ngezixazululo zokuqapha ibhethri ezichwepheshile (i-BMS) ezivumela ukuphathwa okunembile kwezinqubo zokushaja nokukhipha—ngokuqapha ngesikhathi sangempela amapharamitha abalulekile afana nogesi, amandla amanje, nokumelana kwangaphakathi—ngaleyo ndlela inikeza izexwayiso zengozi yangaphambi kwesikhathi nokwelula ubude bebhethri.
