Bubuchwephesha obukhawulezayo obukhawulezayo kunobukhawulezayo, buyenzakalisa ibhetri

ଲେଖକ: ଆଇଫ୍ଲୋପାୱାର - Portable Power Station Supplier

Ingxaki enkulu yeemoto zombane ezicocekileyo, ngumthamo wobomi. Nokuba injineli isekuqaleni kwe-R <000000> D, kunzima kwakhona ukusombulula ipakethe yebhetri enomthamo omkhulu owaneleyo. Nkqu nenqanaba likarhulumente ngeendlela zolawulo, makubonakale iindlela ezihlawulisa ngakumbi.

Kukwanzima ukuyisombulula, imoto yombane esulungekileyo itshaja iingxaki ezicothayo. Xa uhlawula ngokukhawuleza, akusiyo ixesha lomnini, kwaye emva kwayo kukusebenza kakuhle kwezothutho kunye nenkqubo yendlela. Umqhubi uyacotha imizuzu eli-10, iya kwenza ifuthe lebhabhathane kwiilori zokutshaja ezilandelayo.

Ngexesha elifanayo, izithuthi ezininzi zimi kufuphi nemfumba yokutshaja, eya kukhokelela kwindawo yokupaka, iindlela, njl., zithintele ezinye izithuthi. Ukuza kuthi ga ngoku, kukho itekhnoloji yokutshaja ngokukhawuleza, vumela ixesha lokutshaja libe lifutshane ngakumbi.

Nangona kunjalo, indlela yokunciphisa, kuthatha ngaphezu kwemizuzu engama-30. Ngaba kukho iteknoloji yokutshaja enokuthi igqitywe kwimizuzu embalwa? Musa ukuthi, ngokwenene. Ukuba usebenzisa ezinye iibrendi ezizezakho zeemoto ezincinci, kunokwenzeka ukuba izibuko ezitshaja ngokukhawuleza ziya kususwa, izibuko lokutshaja okucothayo kuphela.

Olu hlobo lwendlela yokutshaja ngokwentelekiso, kodwa ifanelekile kuphela kumgama wabahambi yonke imihla. Isixeko esikhulu somhlaba, kunzima ukubiza esi sithuba sobugxwayiba. Abanye abantu bacinga ukuba ixesha lokutshaja licotha, kodwa ubuncinci, kwaye ixabiso liphantsi, kutheni kungenjalo? Kodwa malunga nemoto yokwenyani, intlawulo ekhawulezayo iyasebenza ngakumbi.

Nangona kunjalo, ukutshaja ngokukhawuleza kukwanobungozi. Yintoni onokuyenza ngemizuzu emi-4? intlawulo epheleleyo! Ngokutsho kweFrentshi ebizwa ngokuba yi-ElectricLoading, inethiwekhi yokutshaja ngokukhawuleza yophando lwayo inokuhlawula ngokupheleleyo i-MISSIONE imoto yombane ecocekileyo e-Porsche kwimizuzu emi-4. Nangona ezi ndaba zifana nebhombu enzima, kunokwenzeka ukunciphisa ixesha lokutshaja kwinqwelo yamafutha.

Ndathi krwaqu nje, ndothuka ngokwenene. Ngaba kukho nakuphi na ukukwazi ukubuyisela imoto yamafutha? Noko ke, iingcali zisixelela ukuba le asiyonzululwazi. Ngenxa yesicwangciso sePorsche, amandla okutshaja kaMission yi-350KW isikhululo sokutshaja, kodwa nakwiwebhusayithi esemthethweni, inokubiza i-80% kwimizuzu eyi-15.

Kodwa i-ElectricLoad yenzelwe izixhobo zokutshaja, amandla okusebenza angama-360kW. Xa kuthelekiswa ne-Porsche, i-10 kW kuphela yi-10 kW kuphela, kodwa ixesha lihlulwe ngesibini kwisithathu, abantu abaninzi beshishini baye bathi amathandabuzo. Yintoni eyenzakalayo? Musa ukucinga ukuba imoto yombane iyatshaja, ukufaka nje iplagi kugqityiwe, enyanisweni, kukho ingozi ukuba kukho ukungazi.

Ukukhanya ngo-Agasti, kukho inani leziganeko zomlilo ezibangelwa ukutshaja kwezithuthi zombane. Kubandakanya iLiaoyang, iLiaocheng, kunye nemikhosi emitsha kumlilo waseChengdu; kunye nemoto yomkhweli yombane e-Anhui Tongling. Kwiinyanga nje ezintathu ngoMeyi ka-2018, bekukho abaninzi kwi-16 kwingxelo evulekileyo, kwaye kukho iimeko ze-9 zeengozi, kwaye kukho iimeko ezili-9 zokutshaja ukuzitshisa.

Izizathu zezinye iingozi ziquka ukungaphumeleli kwebhetri, izixhobo zombane isiphaluka esifutshane, Ukuzitshisa, njl. Kuhlalutyo lokugqibela, kuba ibhetri yonzakele kwinkqubo yokutshaja. Isizathu sokuba ibhetri iya kulimala, kubalulekile ukuqala kumgaqo webhetri.

Ekubeni ubuninzi bamandla bukwintsimi ye-electrochemical field, ngumda wethiyori. Intlawulo ekhawulezayo sisahlulo sesona santya silungileyo sokutshaja, kodwa ayikwazi ukugcina isantya sokutshaja samandla aphezulu kulo lonke icandelo. Ngexesha lenkqubo yokutshaja, i-ion ze-lithium kufuneka zifakwe kwaye zilahlwe phakathi kwee-electrode ezimbini, kwaye i-electrode positive negative electrode ayinayo i-oxidation reaction.

Nangona kunjalo, indlela yokuhlawula ngoku ihlawuliswa ngokusetyenziswa kwe-redox reaction, kungekhona indlela yokuhlawula ukuba ibhetri ye-lithium-ion ilandela umthetho wayo. Ngokwendlela yokutshaja yangoku, mhlawumbi iyakwazi ukunciphisa ubomi bebhetri ngama-30%. Ngexesha elifanayo, intlawulo kunye nesantya sokukhutshwa kwebhetri ye-lithium-ion nayo ifanelwe ingqalelo.

Phakathi kwabo, ibhekisela kwintlawulo kunye nokukhupha okwangoku kwiyunithi elinganisiweyo. Xa umthamo olinganisiweyo uyi-100ah, umlinganiselo wentlawulo kunye nokukhupha ngu-0.2c.

Ngokuqhelekileyo, ukutshaja kwangoku kwebhetri ye-lithium ion kusetwa phakathi kwe-0.2c ukuya kwi-1c, inkulu yangoku, ngokukhawuleza ukutshaja, kodwa ubushushu bebhetri bunzulu ngakumbi. Kwelinye icala, ukusetyenziswa kokutshaja okugqithisileyo kwangoku kuya kubangela ukuba umthamo ungagcwali, kuba ixesha lokusabela kwe-electrochemical kwibhetri.

Kusenokubakho ithiyori enyanisweni, ngoku eqhelekileyo multi-positive metal composite iibhetri oxide, ukuba ufuna ukutshaja imizuzu 8, ngokwethiyori sebenzisa 10C yokukhulisa ukwenza. Iingcali ezivela kwintsimi yophando lwebhetri ye-lithium-ion yasekhaya yathi kwiiOlimpiki zaseBeijing kwiminyaka eyi-10, iimvavanyo ezahlukeneyo zenziwa kwimiba eyahlukeneyo. Ibhetri ye-ternary ngelo xesha inokutshajwa kwimizuzu emi-5.

Kuvavanyo, ibhetri ye-lithium-ion ene-dimensional emithathu kwinkqubo yokutshaja ngokukhawuleza, ubushushu abukwazi ukukhutshwa ngokukhawuleza, ukwenzela ukuba amathuba okuqhuma kwanda. Ukuqwalasela imiba yokhuseleko, iqela licinga ukuba le teknoloji ayinakusetyenziswa kwiimoto zombane ezicocekileyo, kuphela kwisithuthi se-hybrid. Kwangaxeshanye, uthungelwano lwamandla esixekweni alunamiqathango esisiseko evumela ukuba umbane omkhulu kangaka ukuthutha.

Masithi ibhasi yi-150KWH yebhetri. Kuthatha imizuzu emi-5 ukubiza. Ibhasi iya kuba yi-100KW umthamo wokubonelela ngombane.

Ukuba kukho amakhulu amawaka eebhasi zokutshaja, kuya kubangela impembelelo enkulu kwigridi. Ukuphuhliswa kwezithuthi zamandla amatsha ngokungathandabuzekiyo kukongeza kunye nokwandiswa kolwakhiwo lwamandla emoto. Ukuma kwinqanaba eliphezulu, ukulungelelanisa umlinganiselo wezakhiwo zamandla kwilizwe sesinye sezizathu ezinzulu emva kwemoto entsha yamandla.

Kodwa buyela kwinqanaba lokusetyenziswa, ubungakanani bobungakanani kunye nokuhanjiswa kweemfumba zokutshaja, indlela yokugubungela isithuthi sombane esisetyenziswe kwisixeko. Kwangaxeshanye, khawulezisa isantya sokutshaja semoto nganye, emva koko ukhawulezise ireyithi yenguqu, yinto entle ngokwenene. Nangona kunjalo, phantsi kolawulo lwangoku lobugcisa kunye neendleko, kwiimeko ezahlukeneyo, abantu abaqhelekileyo bafuna ukunandipha olu hlobo lweenzuzo, mhlawumbi iminyaka emininzi.
