Kwizisombululo zamandla zanamhlanje, iinkqubo zelanga ezingaphandle kwegridi ziya kuba lukhetho kumakhaya amaninzi nakwiishishini, zinika abasebenzisi ukuzimela ngokupheleleyo kwamandla kwaye zibakhulula kwimida kunye nokuguquguquka kwegridi kawonke-wonke. Ibhetri isebenza njengesiseko esibalulekileyo esigcina ukusebenza okuzinzileyo ngelixa ibonelela ngombane ongaphazanyiswa.
Eli nqaku lizaxoxaiiparameter zobugcisa eziphambili zeiibhetri ezingasebenzi kwigridikwaye uchaze ukuba kutheni iiyunithi zeLiFePO4 okwangoku zimele iibhetri ezilungileyo kwiinkqubo zelanga ezingaphandle kwegridi.
Izalathisi eziphambili zokusebenza kweebhetri zelanga ezingaphandle kwegridi
Xa ukhetha ibhetri engasebenzi kwigridi, akwanelanga ukujonga ipharamitha enye. Uvavanyo olupheleleyo lwezi metrics zibalulekileyo kufuneka lwenziwe.
1.ukhuseleko
Ukhuseleko lolona qwalaselo luphambili. Iibhetri zelanga zeLiFePO4 zaziwa ngokuzinza kwazo okumangalisayo kobushushu kunye neekhemikhali, zigxotha ubushushu obuhambayo ngcono kunezinye ezininzi.i-lithium-ioniimodeli.
Xa ubushushu buqala ukubaleka buphezulu kakhulu—ngesiqhelo malunga ne-250°C xa kuthelekiswa malunga150–200 °C kwiI-NCM kunye ne-NCAiibhetri—zinika ukumelana okukhulu nobushushu obuphezulu kunye nokutsha.i-olivineulwakhiwo lwayo luthintela ukukhululwa kweoksijini nokuba kuphantsi kwamaqondo obushushu aphezulu, nto leyo enciphisa ngakumbi umngcipheko womlilo okanye ukuqhuma. Ukongeza, iibhetri zeLiFePO₄ zigcina ulungelelwaniso lwesakhiwo ngexesha lokutshaja kunye nokukhupha—akukho tshintsho kwisakhiwo esingaphantsi kwama-400℃—ukuqinisekisa ukuthembeka kwexesha elide kunye noxolo lwengqondo kwiindawo ezixineneyo. Ngaphezu koko, abakhi beepakethi banokuqinisekisa nge-IEC 62619 kunye ne-UL 9540A ukuba balawula ukusasazwa kwezixhobo.
2.Umthamo wokukhupha ubushushu obunzulu(IsiNgesi)I-DoD）
Ngokuphathelele i-DoD, iibhetri zelanga zeLiFePO4 zibonisa inzuzo ecacileyo, enokufezekisa i-DoD ezinzileyo ye-80%-95% ngaphandle kokwenzakala. I-DoD yeebhetri ze-lead-acid idla ngokukhawulelwa kwi-50% ukuthintela ukonakala komthamo osisigxina ngenxa ye-plate sulfation.
Ngenxa yoko, i-a10kWhinkqubo yokugcina amandlaUkusebenzisa iteknoloji yeLiFePO4 kunokubonelela nge-8-9.5kWh yamandla asebenzisekayo, ngelixa inkqubo ye-lead-acid inokubonelela kuphela malunga ne-5kWh.
3.Ixesha Lokuphila kunye Nomthamo Womjikelo
Ixabiso lotyalo-mali lobuchwepheshe beLiFePO4 liza kuvelisa imbuyekezo ngobomi obude bemveliso. Ezo zine-lead-acid zihlala zisiba nokwehla ngokukhawuleza kokusebenza emva kwemijikelo engama-300-500 kuphela yokusetyenziswa kakhulu.
Kodwa iibhetri zeLiFePO4 zibonelela ngobomi bomjikelo onzulu obudlula imijikelo engama-6,000 (ngaphezulu kwe-80% yeDoD). Nokuba zinomjikelo omnye wokukhupha itshaja ngosuku, zinokusebenza ngokuzinzileyoixhomekeke kuIminyaka eli-15.
4.Ubuninzi bamandla
Uxinano lwamandla di-efiniukuba ibhetri ingagcina amandla angakanani ngomthamo okanye ubunzima obuthile. Ubuninzi bamandla eebhetri zelanga zeLiFePO4 buphezulu kakhulu. Ngenxa yobukhulu obufanayo, zinobukhulu obuncinci kunye nobunzima obulula, zigcina indawo yokufaka kwaye zenza kube lula ukuthutha.
5.Ukusebenza kakuhle kokutshaja
Ukusebenza kakuhle kwebhetri yelanga yeLiFePO4 ukuya nokubuya yi-92-97%. Iibhetri ze-lead-acid azisebenzi kakuhle kakhulu, kwaye ukusebenza kakuhle kwe-reverse trip kumalunga ne-70-85%. Kwi-10 kWh nganye yamandla elanga afunyenweyo, iinkqubo ze-lead-acid ziguqula i-15-25% yamandla elanga abe yinkunkuma yobushushu. Kwaye ukulahleka kwebhetri ye-LFP yi-0.3-0.8 kWh kuphela.
6.Iimfuneko zoLondolozo
Fokanye iibhetri ze-lead-acid ezigcwele amanziukugcinwa igubungelaUkuhlolwa rhoqo kwamanqanaba e-electrolyte kunye nokuthintela ukugqwala kokuphela.
Iibhetri zelanga zeLiFePO4 azinazo iimfuneko zokugcinwa, nto leyo engafuniaukucoca amanzi okucwangcisiweyo okanye ukucoca isiphelo sendlela, okanye ukugcinwa kwentlawulo yokulinganisa.
7.Iindleko zokuqala xa kuthelekiswa neendleko zomjikelo wobomi
Ixabiso eliphambili leebhetri zeLiFePO4 liphezulu ngokwenene.I-FePOInkqubo ye-PV engaphandle kwegridi ezi-4 ibonisa iindleko ezingcono zobunini. Bangaukugcina ubomi obude bokusebenza kwaye kufuna ulondolozo oluncinci ngelixa kufezekisa ukonga kwamandla okuphezulu. Iziphumo zexesha elide zolu tyalo-mali zikhokelela ekunikezelweni kwexabiso elipheleleyo eliphezulu.
8.Uluhlu lobushushu obubanzi
Iibhetri ze-lead-acid zifumana ukuwohloka kokusebenza kwazo xa zisebenza kwiindawo ezibandayo zobushushu. Iibhetri zelanga zeLiFePO4 zinoluhlu olubanzi lobushushu obusebenzayoukusuka-20°C ukuya kuma-60°C.
9.Ubuhlobo kwiNdalo kunye nokuZinza
Iibhetri zelanga zeLiFePO4 azinazo iintsimbi ezinzima ezifana nelothe, nto leyoziyingozi kwiindalo kwaye ifuna iindlela ezikhethekileyo nezintsonkothileyo zokuphinda kusetyenziswe. I-electrolyte esetyenziswa kwiibhetri ze-lead-acid yi-sulfuric acid, edlakadlaka kwaye inokubangela ukutsha okukhulu. Ukuchitheka okanye ukuvuza kunokwenza umhlaba namanzi abe yi-asidi, onakalise izityalo kunye nezidalwa zasemanzini.
Zingaphi iibhetri zelanga zeLiFePO4 ozidingayo
Ukufumanisa ubungakanani bebhetri linyathelo elibalulekileyo kuyilo lwenkqubo yelanga engaphandle kwegridi. Masihambe ngomzekelo ukuze sibone ukuba yenziwa njani:
(1) Iingcamango:
Ukusetyenziswa kwamandla imihla ngemihla: 5 kWh
Iintsuku zokuzimela: iintsuku ezi-2
Ibhetri esebenzisekayo i-DoD: 90% (0.9)
Ukusebenza kakuhle kwenkqubo: 95% (0.95)
l Inkqubo yeVoltage: 48V
Ibhetri enye ekhethiweyo: 5.12 kWh ROYPOW LiFePO4 Ibhetri yelanga
(2) Inkqubo Yokubala:
l Imfuneko Yokugcina Yonke = 5 kWh/ngosuku × iintsuku ezi-2 = 10 kWh
l Umthamo weBhanki yeBhetri iyonke = 10 kWh ÷ 0.9 ÷ 0.95 ≈ 11.7 kWh
l Inani leebhetri = 11.7 kWh÷ 5.12 kWh = iibhetri eziyi-2.28
Isiphelo: Ekubeni iibhetri zingenakuthengwa zodwa, udinga ezi bhetri zi-3, ezikwabonelela ngomda wokhuseleko omkhulu ngaphaya kwemfuneko yakho yokuqala ye-10 kWh.
Ezinye izinto ekufuneka uziqwalasele xa ukhetha ibhetri yelanga yeLiFeO4
üUkuhambelana kwenkqubo:Tshatisa i-voltage yebhetri engekho kwigridi kunye ne-inverter/ishaja yakho, kwaye sebenzisa isilawuli esineprofayili yokutshaja ye-LFP. Musa ukutshaja ngaphantsi kwe-0 °C, kwaye ujonge itshaja ephezulu yebhetri kunye nomsinga wokukhupha umbane ngokuthelekisa ubungakanani be-inverter yakho.
üUkulinganiswa Kwexesha Elizayo kunye noYilo lweModular:Cwangcisa ukongeza umthamo ngeemodyuli ezifanayo. Faka ucingo ngeebhasi ukuze umtya ngamnye ubone ubude bendlela efanayo, kwaye ulinganise ii-voltages ngaphambi kokuba zilingane ukuze uphephe ukungalingani. Landela uthotho lomenzi kunye nemida ehambelanayo.
üUphawu kunye newaranti:Kufuneka ufune amagama alula, anje ngeminyaka egutyungelweyo, imida yokujikeleza/ukuphuma kwamandla, kunye nomthamo wewaranti yokuphela kwayo. Ngaphaya koko, iimpawu ezineziqinisekiso zokhuseleko (IEC 62619 kunye ne-UL 1973) kunye nenkxaso yenkonzo yasekuhlaleni kufuneka zikhethwe.
