Namuhla, namuhla, ubuchwepheshe obuphezulu obuhlukahlukene buvela ezimpilweni zethu, buletha ukuphila kwethu kube lula, khona-ke ingabe uyaqonda ukuthi lobu buchwepheshe obuphezulu bungase buqukathe ibhalansi yokushaja? Ibhethri ye-lithium ion muva nje Emakethe, ngenxa yokuthuthukiswa kwayo okukhulu, isabelo sayo semakethe sikhuphuke ngokushesha okukhulu. Umthamo wokugcina amandla webhethri ye-lithium-ion uyamangalisa kakhulu, noma kunjalo, umthamo weyunithi yebhethri eyodwa usephansi kakhulu kusuka ku-voltage noma kusuka kumanje, futhi awukwazi ukuhlangabezana nenjini ye-hybrid. Ukufana nobuningi bamaseli ebhethri kungakhuphula lamanje elinikezwa ibhethri, futhi ubuningi bamaseli ebhethri bungakhuphula i-voltage ehlinzekwa yibhethri.

Ibhalansi yokushaja (isifinyezo silingana nokushajwa) yishaja ebhalansisa izici zebhethri. Isho ukungalingani kwamandla kagesi webhethri ngenxa yomehluko ngamunye kanye nokwehluka kwezinga lokushisa ngenxa yebhethri phakathi nebhethri. Ukuze uvimbele lo mkhuba wokungalingani, i-voltage yokushaja yephakethe lebhethri kufanele yengezwe futhi ibhethri livulwe futhi lishajwe ukuze kulinganiswe izici zebhethri ngalinye eqenjini lebhethri le-lithium-ion futhi andise impilo yebhethri.

. Uma i-voltage idlula ibanga elivumelekile, ibhethri ye-lithium ion yonakala kalula. Uma i-voltage idlula umkhawulo ongaphezulu nophansi (njengesibonelo sebhethri ye-ion ye-nanophosphate, umkhawulo ophansi we-voltage ngu-2V, umkhawulo ophezulu we-voltage ngu-3.

6V), ingalimaza ibhethri. Umphumela uwukusheshisa okungenani isivinini sokuzikhipha kwebhethri. I-voltage ephumayo yebhethri izinzile phakathi kwenani elibanzi lokushajwa (i-SOC), futhi ubungozi bokuchezuka kwamandla kagesi buncane.

Kodwa-ke, kuzo zombili iziphetho zobubanzi bokuphepha, ama-ups namapayipi ejika lokushaja aphakeme. Ngakho-ke, njengezinyathelo zokuvimbela, i-voltage kufanele ibhekwe ngokuqinile. Ubuchwepheshe obujwayelekile bokushaja obunokulinganisela buhlanganisa ukushaja kokulinganisa kokumelana okuhambisanayo, ukulingana okuvulekile okuhlobene nokumelana, ukushaja okulinganayo kokulinganisa kwamandla ebhethri, ukushaja kokulingana kwe-capacitor, ukushaja kokulinganisa kokuguquguquka okusuka phansi, ukushaja kokulinganisa kwe-inductance, njll.

Ibhethri ye-ion kufanele ixhunywe kuchungechunge, ibhethri ngalinye kufanele lishajwe, ngaphandle kwalokho lizothinta ukusebenza nempilo yalo lonke isethi yamabhethri ngesikhathi sokusetshenziswa. I-chip yebhethri yeseli eyodwa ye-lithium-ion ekhona ayinawo umsebenzi wokulawula ukushaja olinganiselayo, ukuxhuma imisebenzi yokulawula ukushaja ye-lithium ion yokuvikela ibhethri ye-chip ye-chip equalization ku-CPU. Kwenziwa ukuxhumana kwe-serial ngama-chips avikelayo futhi kunwetshwe umjikelezo wokuvikela.

Ubunkimbinkimbi nobunzima bomklamo kunciphisa ukusebenza kahle nokuthembeka kwesistimu, futhi kwengeza ukusetshenziswa kwamandla. Indlela evamile yokungenzi lutho: Kusistimu yokuphatha ibhethri evamile, iyunithi yebhethri ngayinye ixhunywe ukumelana nomthwalo ngokusebenzisa iswishi. Lesi sijikelezo sokwenziwa singakhipha iyunithi eyodwa ekhethiwe.

Kodwa-ke, le ndlela isebenza kuphela ekukhuphukeni kwamandla kagesi weseli yebhethri eliqine kakhulu ekucindezelekeni kwemodi yokushaja. Ukuze unciphise ukusetshenziswa kwamandla, lolu hlobo lwesekhethi ngokuvamile luvumela kuphela ukukhishwa okuncane kwamanje okungaba ngu-100 mA, okubangela ukulinganisa kweshaja okungenzeka kufike emahoreni ambalwa. Lapho ukukhiqizwa kwephakethe lebhethri le-lithium-ion lide, njengoba ukusetshenziswa kwamandla okumile kwepuleti ngalinye lokuvikela kuhlukile futhi izinga lokuzikhipha kwebhethri ngalinye lihlukile, i-voltage yebhethri yentambo ngayinye ayihambisani.

Linganisa umsebenzi wokulinganisa i-voltage yephakethe lebhethri le-lithium ion, ukuze umthamo womthamo webhethri ungafinyelela ukusebenza kahle okuphezulu kwephakethe lebhethri. Indlela yebhalansi esebenzayo: Kunezindlela eziningi zebhalansi ezisebenzayo ezintweni ezihlobene, zonke ezinesici sokulondoloza sokudlulisa amandla. Uma i-capacitor isetshenziswa njengento yokugcina, i-capacitor ixhunywe kuwo wonke amaseli ebhethri ukuze ibe ne-switch array enkulu.

Indlela ephumelela kakhulu ukugcina amandla endaweni kazibuthe. Izingxenye ezibalulekile kusekethe ama-transformer. I-prototype yesekethe ithuthukiswa Ithimba Lokuthuthukiswa Kwe-Infertile kanye ne-VogtelectronicComponentsGmbH.

Isekhethi yegiya elihambisanayo yengezwa ebhethrini ngalinye leqembu lebhethri le-lithium ion ukufeza inhloso yokuletha. Kule modi, lapho ibhethri ishajwa ngokugcwele okokuqala, idivayisi yokulinganisa ingakwazi ukuyivimbela ekushajweni ngokweqile futhi iguqule amandla engeziwe ibe ukushisa, futhi iqhubeke nokushaja ibhethri elinganele. Le ndlela ilula, kodwa izodala ukulahlekelwa kwamandla, ayifanele uhlelo lokushaja okusheshayo.

Ngaphambi kokushajwa, ibhethri ngalinye likhishwa lifike ezingeni elifanayo ngomthwalo ofanayo, bese lenza ukushaja kwamanje njalo ukuze kuqinisekiswe ukuthi ibhalansi phakathi kwamabhethri inembe kakhulu. Kodwa-ke, mayelana namaphakethe ebhethri, ngenxa yomehluko obonakalayo phakathi kwabantu ngabanye, kunzima ukuzuza umphumela omuhle ongaguquki ngemva kokujula kweyunithi yebhethri ngayinye. Ngisho noma umphumela ofanayo ufinyelelwa ngemva kokukhishwa, ukungalingani okusha kwenzeka ngesikhathi sokushaja.
