I-2. Uhlalutyo lwentsebenzo yendlela yokuhlaziywa komsebenzi: Iimvavanyo zokuhlukumeza zinganceda ekumiseleni ukonakala kwendlela yebhetri ngexesha lokuhlawula, ukunyuka kwayo, njl njl.
3. Uvavanyo loKhuseleko: Uvavanyo lokwaluphala kunye nokuchonga ukwaluphala uncedo lokufumana iingozi zokhuseleko kunye nokungasebenzi kakuhle okunokwenzeka ngexesha lokusetyenziswa kwebhetri. Umzekelo, iimvavanyo ezilupheleyo zinokunceda ukufumanisa ukusebenza kwezokhuseleko phantsi kweemeko ezinje ngokugqithisileyo, ukukhululwa ngaphezulu, kunye nobushushu obuphezulu, kunye nokuphuculwa kwenkqubo yebhetri kunye neenkqubo zokhuselo lwebhetri.
I-4. Uyilo olufanelekileyo: ngokwenza uvavanyo olulupheleyo kunye nokufunyanwa okulupheleyo kwiibhetri, izazinzulu zinokuqonda iimpawu kunye neenjineli zebhetri, ziyakwazi ukuphucula ukusebenza kwebhetri kunye nokuphucula intsebenzo yebhetri kunye nexesha lokuphila.
Kwisishwankathelo, iimvavanyo ezilupheleyo kunye nokufunyanwa okulupheleyo kubaluleke kakhulu ukuqonda nokuvavanya ukusebenza kunye nobomi beebhetri ze-lithium-ion, ezinokusinceda uyilo olungcono kwaye basebenzise iibhetri kunye nokukhuthaza uphuhliso lwetekhnoloji.
Zeziphi iinkqubo zokuvavanywa kwebhetri ze-lithium kunye novavanyo lweprojekthi?
Ngokuvavanywa nokubekwa kweliso ekwakheni le misebenzi ilandelayo, sinokubuqonda ngcono utshintsho kunye nohlengahlengiso lwebhetri ngexesha lokusetyenziswa, kunye nokunyaniseka, iimpawu zendlela yebhetri phantsi kweemeko ezithile zomsebenzi.
I-1. Ukuphelisa amandla: Ukupheliswa komthamo yenye yeempawu eziphambili zobomi bebhetri. Uvavanyo lokwaluphala luya kwenza ukuba intlawulo kunye nokukhupha imijikelezo yokulinganisa intlawulo ye-cyclic kunye nenkqubo yokukhupha ibhetri. Vavanya ukonakaliswa komthamo webhetri ngokulinganisa utshintsho kubume bebhetri emva komjikelo ngamnye.
2. Ubomi bomjikelo: Ubomi bee-switcley Boicfere Ibhekisa ukuba bangaphi intlawulo epheleleyo kunye nokukhupha imijikelezo yebhetri. Uvavanyo lokwaluphala lwenza inani elikhulu lentlawulo kunye nokugxotha imijikelezo yokuvavanya umjikelo wobomi bebhetri. Ngokwesiqhelo, ibhetri ithathwa njengezifikelelele esiphelweni sobomi baso xa amandla ayo alathisa ipesenti ethile yenqanaba lokuqala (umz.
3. Ukunyuka kokungaxhathisi sangaphakathi: Ukuxhathisa kwangaphambili luyinto ebalulekileyo yebhetri, echaphazela ngokuthe ngqo intlawulo yebhetri kunye nokukhupha impumelelo kunye nokuguqulwa kwempumelelo kwamandla. Uvavanyo oludala luvavanya ukwanda kwengxowa-mali yokungaxhathisi ngaphakathi ngokulinganisa utshintsho kwindlela engaphakathi kwebhetri ngexesha lokuhlawula kunye nokukhupha.
I-4. Umsebenzi wokhuseleko: Uvavanyo lokudala lubandakanya ukuvavanywa kwentsebenzo yokhuseleko yebhetri. Oku kunokubandakanya ukulinganisa impendulo kunye nokuziphatha kwebhetri phantsi kweemeko ezingaqhelekanga ezinjengobushushu obuphakathi, ukugqithisa, kunye nokukhutshwa kwebhetri phantsi kwale meko.
5. Iimpawu zobushushu: Iqondo lobushushu linefuthe elibalulekileyo ekusebenzeni kwebhetri kunye nobomi. Uvavanyo lokwaluphala lunokulinganisa ukusebenza kweebhetri phantsi kweemeko zobushushu ezahlukeneyo ukuvavanya impendulo yebhetri kunye nentsebenzo kuguquko lobushushu.
Kutheni le nto ukunganyangeki kwangaphakathi kwebhetri emva kokuba isetyenziselwe ixesha elithile? Iza kuba yintoni impembelelo?
Emva kokuba ibhetri isetyenziselwa ixesha elide, ukuxhathisa ngaphakathi kuyanda ngenxa yokwaluphala kwezixhobo zebhetri kunye nolwakhiwo. Ukuxhathisa ngaphakathi kukuchasana nokuxhaphaza okukuhambayo xa kuhamba ibhetri. Igqitywe ziimpawu ezinzima zendlela eya ngaphakathi yebhetri ecetywayo ye-elektrolyte, izixhobo ze-elektrode, oovihokelo lwangoku, ii-elektrolytes, njl. Njl.
I-1. Ukuhla kwevolthi: Ukuxhathisa i-voltage: Ukuxhathisa ngaphakathi kuya kubangela ibhetri ukuba ivelise i-voltaged yehla ngexesha lokukhupha. Oku kuthetha ukuba i-voltage yokwenyani iya kuphantsi kune-voltage evulekileyo yebhetri, ngaloo ndlela kuncitshiswe amandla ebhetri.
2. Ukulahleka kwamandla: Ukuxhathisa kwangaphakathi kuya kubangela ibhetri ukuvelisa ubushushu ongezelelweyo ngexesha lokukhubeka, kwaye obu bushushu bumela ilahleko yamandla. Ilahleko yamandla inciphisa ukuguqulwa kwetekisi, ibangela ibhetri ukuba ibonelele ngamandla amancinci phantsi kweemeko ezifanayo zokukhupha.
3. Iziphumo zombane ezincitshisiweyo: Ngenxa yokwanda kokuxhathiswa kwangaphakathi, ibhetri iya kuba ne-voltage enkulu kwaye ilahleko yamandla xa ikhupha imveliso ephakame ngokufanelekileyo. Ke ngoko, ukukhululeka kokusebenza kakuhle kwaye amandla okukhupha amandla ebhetri kuyancipha.
Ngamafutshane, ukwanda kokuxhathisa kwangaphakathi kuya kubangela ukunqunyulwa kwebhetri ukuncipha, ngaloo ndlela kuchaphazela amandla ebhetri, ukukhupha amandla, kunye nokusebenza ngokubanzi. Ke ngoko, ukunciphisa ukunganyangeki kwangaphakathi kwebhetri kunokuphucula ukusebenza kwetekisi kunye nokusebenza.
