Isingeniso:
Enye yezinkinga ezinkulu ze-amabhethri e-lithiumukubola komthamo, okuthinta ngqo impilo yesevisi yabo kanye nokusebenza kwabo. Izizathu zokubola komthamo ziyinkimbinkimbi futhi ziyahlukahluka, kufaka phakathi ukuguga kwebhethri, indawo yokushisa okuphezulu, imijikelezo yokushaja njalo kanye nokukhipha, ukushaja ngokweqile kanye nokukhipha okujulile.
Ukubonakaliswa okuyinhloko kokubola komthamo webhethri le-lithium ukwehla kancane kancane komthamo wokukhipha, okungukuthi, ukwehla komthamo webhethri kanye nokukhuthazela, futhi lokhu kubola akunakulungiseka futhi kuzosheshisa inqubo yokuguga kwebhethri, ngakho-ke ukuze kuvinjelwe ukubola komthamo izinyathelo:
1. Ukuphathwa kokukhokhiswa nokukhishwa kwemali
Yakha uhlelo lokushaja nokukhipha imali olufanele:gwema ukushaja ngokweqile noma ukukhipha ngokweqile ibhethri isikhathi eside, futhi uqinisekise ukuthi ibhethri le-lithium lisebenza ngaphakathi kwefasitela le-voltage elifanele ukuze unciphise ukucindezeleka ngokweqile ezintweni ze-electrode.
Nciphisa ugesi osheshayo bese usetha i-voltage efanele yokusika i-charge: Lokhu kusiza ukunciphisa ukucindezeleka kokushisa kanye namakhemikhali ngaphakathi kwebhethri le-lithium kanye nokulibazisa ukubola komthamo.
2. Ukulawula izinga lokushisa
Gcina ibhethri le-lithium lisezingeni lokushisa elifanele:Indawo eshisa kakhulu izosheshisa ukusabela kwamakhemikhali ebhethri, okuholela ekuboleni okukhulu kwamandla; kanti izinga lokushisa eliphansi lizokwandisa ukumelana kwangaphakathi kwebhethri futhi lithinte ukusebenza kahle kokukhipha. Ngakho-ke, ukusetshenziswa kwezinhlelo zokupholisa ezisebenzayo noma izinto zokuvikela kungathuthukisa kakhulu isimo sokusebenza kwebhethri futhi kwandise isikhathi sayo sokuphila.
3. Ukuthuthukiswa kwe-algorithm yesofthiwe
Ukusetshenziswa kohlelo lokuphatha ibhethri oluhlakaniphile (I-BMS):qapha amapharamitha ahlukahlukene ebhethri ngesikhathi sangempela futhi ulungise ngokuguquguqukayo isu lokushaja nokukhipha ibhethri ngokuya ngedatha. Isibonelo, lapho izinga lokushisa lebhethri litholakala ukuthi liphezulu kakhulu noma selizoshajwa ngokweqile, i-BMS ingalungisa ngokuzenzakalelayo izinga lokushaja noma iyeke ukushaja okwesikhashana ukuze ilondoloze impilo yebhethri.
4. Ukulungiswa nokubuyiselwa njalo
Imijikelezo yokushaja nokukhipha ngezikhathi ezithile:Imijikelezo yokushaja nokukhipha amandla njalo kanye nezinye izindlela zokulungisa ibhethri kungasiza ekubuyiseleni ezinye izinto ezisebenzayo, ngaleyo ndlela kwehlise izinga lokubola kwamandla.
5. Ukuvuselela nokuphinda usebenzise
Ungalahli amabhethri e-lithium angcolile ngokuthanda kwakho.Zinikeze izikhungo zokuvuselela amabhethri ukuze zelashwe ngobungcweti, zikhiphe izinto eziyigugu njenge-lithium ne-cobalt kuzo ukuze kukhiqizwe amabhethri amasha, okungagcini nje ngokufaka isandla ekusetshenzisweni kwezinsiza okusimeme, kodwa futhi kunciphisa umthwalo wemvelo.
6. Ukuthuthukiswa kwezinto ezibonakalayo kanye nokusungula izinto ezintsha
Thuthukisa izinto ezintsha ze-electrode:Cwaninga ngezinto ze-electrode ezinhle ezizinzile kanye nezinto ze-electrode ezimbi ezinomthamo wokugcina we-lithium ophezulu, njengezinto ezisekelwe ku-silicon noma i-lithium metal, ukuze unciphise ukulahlekelwa kwamandla emijikelezweni yokushaja nokukhipha.
Lungiselela ifomula ye-electrolyte:Ngokuthuthukisa ifomula ye-electrolyte, ukunciphisa imikhiqizo yokubola kwe-electrolyte, ukunciphisa izinga lokukhula kwe-impedance yangaphakathi yebhethri le-lithium, ngaleyo ndlela kwandiswe impilo yebhethri.
Isiphetho
Ukuxazulula inkinga yokubola komthamo webhethri le-lithium kudinga ukubambisana kanye nokusungula izinto ezintsha, kusukela ezintweni zokwakha, ukuklama, ukuphathwa, ukunakekelwa kanye nezinye izici ukuze kwandiswe impilo yebhethri futhi kuthuthukiswe ukusebenza. Ngokuthuthuka okuqhubekayo kobuchwepheshe kanye nocwaningo olujulile, ngikholelwa ukuthi izixazululo ezisebenza kahle kakhulu zizovela esikhathini esizayo.
Amandla eHeltecungumlingani wakho othembekile kumabhethri e-lithium. Ngokugxila okungapheli ocwaningweni nasekuthuthukisweni, amabhethri e-lithium aphezulu kanye nohlu olubanzi lwezesekeli zamabhethri, sinikeza izixazululo ezifika kanye ukuze kuhlangatshezwane nezidingo ezishintshayo zomkhakha. Ukuzibophezela kwethu emikhiqizweni ephakeme, izixazululo ezenzelwe wena kanye nokubambisana okuqinile kwamakhasimende kusenze saba ukukhetha okuthandwayo kwabakhiqizi bephakethe lamabhethri kanye nabaphakeli emhlabeni jikelele.
Uma unemibuzo noma ungathanda ukwazi okwengeziwe, sicela ungangabazi ukungithumelelaxhumana nathi.
