Ngophuhliso olukhawulezayo loluntu, iibhetri zethu ze-lithium-ion nazo zikhula ngokukhawuleza. Ngoko uyaluqonda ulwazi oluneenkcukacha lweebhetri ze-lithium-ion? Okulandelayo, vumela uXiaobian akhokele wonke umntu ukuba afunde ngakumbi ngolwazi. Ibhetri yeLithium-ion yeyona ndawo ifanelekileyo yombane ngenxa yombane osebenza ngamandla, ubungakanani obuncinci, umgangatho wokukhanya, akukho siphumo sokukhumbula, akukho ngcoliseko, ukuzikhupha, ubomi bomjikelo omde ngumbane ofanelekileyo.

Ekusetyenzisweni okwenyani, ukuze ufumane i-voltage ephezulu yokukhupha, ubuncinci iibhetri ezimbini ze-lithium ion zisetyenziswa ngokubanzi kuthotho ukusebenzisa ipakethi yebhetri ye-lithium ion. Okwangoku, ipakethe yebhetri ye-lithium-ion isetyenziswe ngokubanzi kwiinkalo ezahlukeneyo ezifana neelaptops, iibhayisekile zombane kunye namandla asecaleni. Ngoko ke, indlela yokusebenzisa ipakethi yebhetri ye-lithium ion xa utshaja kubaluleke kakhulu, kunye neendlela ezininzi zokutshaja ezisetyenziswa rhoqo kwiipakethe zebhetri ze-lithium ion kunye nendlela yokutshaja efanelekileyo ekholelwayo yile ndlela ilandelayo: 1 Intlawulo ye-series eqhelekileyo, yangoku, i-ion ze-lithium Ukutshaja kwepakethi yebhetri kuhlawuliswa ngokubanzi kuthotho, okubalulekileyo kuba indlela yokuhlawula uthotho ilula kwaye kulula ukuyiphumeza.

Nangona kunjalo, ngenxa yokwahlukana kwamandla, ukuchasana kwangaphakathi, iimpawu zokunciphisa, ukuzikhupha phakathi kweeseli ezisekelwe kwiseli enye, xa uhlawulisa i-lithium ion ibhetri pack, iseli incinci kunebhetri kwi-cell cell cell cell. Kuya kuhlawuliswa ngokupheleleyo, ngeli xesha, ezinye iibhetri azizange zizaliswe ngumbane, ukuba uqhubeka uhlawula intlawulo, ibhetri ye-lithium ion ehlawuliswayo inokuthi ihlawule. Ukutshaja okugqithisileyo kweebhetri ze-lithium-ion kuya konakalisa kakhulu ukusebenza kwebhetri, kwaye kunokubangela ugqabhuko-dubulo, olukhokelela kukwenzakala komntu.

Ngoko ke, ukwenzela ukuthintela ukutshaja ngokugqithiseleyo kwebhetri ye-lithium ion enye, ngokuqhelekileyo inikezelwa ngenkqubo yokulawula ibhetri (i-BatteryManagementSystem, efinyeziweyo njenge-BMS), kwaye ibhetri nganye ye-lithium ion ihlawuliswa kakhulu yinkqubo yokulawula ibhetri. Xa ukutshaja kuhlawuliswa, ukuba i-voltage yebhetri ye-lithium ion enye ifikelela kwi-voltage yokukhusela i-overcharge, inkqubo yokulawula ibhetri inqumla yonke isiphaluka sokutshaja kwaye uyeke ukutshaja ukuthintela iibhetri zomntu ukuba zigqithise, okubangelwa enye ibhetri yokutshaja. Ibhetri yeLithium-ion ayinakutshajwa ngokupheleleyo.

Emva kweminyaka yophuhliso, iibhetri ze-lithium iron phosphate dynamic lithium-ion ziye zanelisa ngokusisiseko iimfuno zezithuthi zombane, ngakumbi iimoto zombane ezicocekileyo ngenxa yokhuseleko oluphezulu kunye nokusebenza kakuhle komjikelo. Le nkqubo ifumaneka ngokusisiseko kwimveliso yobuninzi. Nangona kunjalo, ukusebenza kwebhetri ye-lithium ye-iron phosphate ion ihluke kwezinye iibhetri ze-lithium ion, ngokukodwa iimpawu zayo zombane kunye neebhetri ze-lithium-manganese acid lithium-ion.

Ukongezelela, nangona ezinye iinkqubo zokulawula ibhetri zinomsebenzi wokulinganisa, ngenxa yeendleko, ukutshatyalaliswa kobushushu, ukuthembeka, njl., i-balanced current yenkqubo yokulawula ibhetri idla ngokuba yincinci kakhulu kunomjelo ohlawulwayo ngoku, ngoko umphumo wokulinganisa awulungile kakhulu. Ngokucacileyo, iya kubonakala.

Ezinye iibhetri zecandelo elilodwa azihlawuliswanga ngokupheleleyo, nto leyo ecacileyo ngokukodwa malunga nepakethe yebhetri ye-lithium-ion ukuba ibe nokutshaja okuphezulu kwangoku, njenge-lithium ion ibhetri pack yezithuthi zombane. 2 Inkqubo yolawulo lwebhetri kunye nolungelelwaniso lomatshini wokutshaja kunye nenkqubo yolawulo lwebhetri yentlawulo sesona sixhobo siqondwa ngokupheleleyo ekusebenzeni kwebhetri kunye nombuso. Ngoko ke, ngokuseka uqhagamshelwano phakathi kwenkqubo yolawulo lwebhetri kunye netshaja, itshaja inokuqonda ulwazi lwebhetri ngexesha lokwenyani, ngaloo ndlela isombulula ixesha lokutshaja ibhetri ngokufanelekileyo.

Umgaqo wenkqubo yolawulo lwebhetri kunye nemowudi elungelelanisiweyo yokutshaja yile: inkqubo yokulawula ibhetri ibeka iliso kwimeko yangoku yebhetri (efana nobushushu, umbane webhetri enye, ukusebenza kwebhetri ngoku, ukungaguquguquki kunye nokunyuka kobushushu, njl. njl.). Kwaye usebenzise ezi parameters ukuqikelela ubuninzi obuvumelekileyo bokutshaja okwangoku bebhetri yangoku; ngexesha lokutshaja, iinkqubo zokulawula ibhetri kunye neeshaja zixhunywe ngemigca yonxibelelwano, kunye nokuphumeza ukwabelana ngedatha.

Inkqubo yolawulo lwebhetri iya konyusa amandla ombane, awona mandla ombane aphezulu ebhetri enye, ubushushu obuphezulu, awona mandla aphezulu avumelekileyo ombane wokutshaja, awona mandla aphezulu avumelekileyo ombane webhetri enye kunye nobukhulu obuvumelekileyo bokutshaja ngoku kwitshaja, itshaja inokulawulwa ngokoqhagamshelo kulawulo lwebhetri Ulwazi olubonelelwe yinkqubo luya kutshintsha isicwangciso sayo sokutshaja kunye nesiphumo sangoku. Xa ubuninzi obuvumelekileyo bangoku bokutshaja obubonelelwa yinkqubo yolawulo lwebhetri bungaphezulu koyilo lwangoku umthamo wetshaja, itshaja iya kuhlawuliswa ngokowona mkhulu wemveliso yangoku yoyilo; xa i-voltage yebhetri kunye nobushushu budlula umda, inkqubo yokulawula ibhetri inokubona ngexesha langempela kwaye yazise ukutshaja ngexesha. Xa umsinga wokutshaja mkhulu kunowona mkhulu uvumelekileyo wokutshaja okwangoku, itshaja iqalisa ukulandela owona msinga wokutshaja ovumelekileyo, ngokufanelekileyo ithintele ibhetri ekutshajisweni ngokugqithisileyo, ifikelele kwiinjongo zokwandisa ubomi bebhetri.

Nje ukuba ukusilela kukwinkqubo yokutshaja, inkqubo yolawulo lwebhetri inokuseta ubuninzi obuvumelekileyo bokutshaja ngoku ukuya kwi-0, ukuze itshaja iyeke ukusebenza, ngaloo ndlela ithintele ingozi kwaye iqinisekise ukhuseleko lokutshaja.
