Ezixazululweni zamandla zesimanje, izinhlelo zelanga ezingaphandle kwegridi ziyaba ukukhetha emakhaya amaningi kanye namabhizinisi, zinikeza abasebenzisi ukuzimela okuphelele kwamandla futhi zibakhulule ekulinganiselweni nasekushintsheni kwegridi yomphakathi. Ibhethri lisebenza njengesisekelo esibalulekile esigcina ukusebenza okuzinzile ngenkathi sinikeza ukunikezwa kwamandla okungaphazamiseki.
Lesi sihloko sizoxoxaamapharamitha obuchwepheshe abalulekileamabhethri angaphandle kwegridifuthi uchaze ukuthi kungani amayunithi e-LiFePO4 okwamanje emelela amabhethri amahle kakhulu ezinhlelo zelanga ezingaphandle kwegridi.
Izinkomba Zokusebenza Ezibalulekile Zamabhethri Elanga Angekho Kugridi
Uma ukhetha ibhethri elingaphandle kwegridi, akwanele ukubheka ipharamitha eyodwa. Ukuhlolwa okuphelele kwalezi zilinganiso ezibalulekile eziyisisekelo kudingeka kwenziwe.
1.Ukuphepha
Ukuphepha yikona okubalulekile okufanele kucatshangelwe. Amabhethri elanga e-LiFePO4 aziwa ngokuqina kwawo okushisa kanye namakhemikhali, axosha ukuqhuma kokushisa kangcono kuneningi.i-lithium-ionamamodeli.
Njengoba izinga lokushisa lokuqala lokubaleka liphezulu kakhulu—ngokuvamile cishe ama-degrees angu-250°C uma kuqhathaniswa cishe150–200 °C yeI-NCM kanye ne-NCAamabhethri—anikeza ukumelana okukhulu kakhulu nokushisa ngokweqile nokusha.i-olivineisakhiwo sivimbela ukukhishwa komoya-mpilo ngisho nangaphansi kwamazinga okushisa aphezulu, okunciphisa kakhulu ingozi yomlilo noma ukuqhuma. Ngaphezu kwalokho, amabhethri e-LiFePO₄ agcina ubuqotho besakhiwo ngesikhathi somjikelezo wokushaja nokukhipha—akukho zinguquko zesakhiwo ezingaphansi kuka-400℃—ukuqinisekisa ukuthembeka kwesikhathi eside kanye nokuthula kwengqondo ezindaweni ezidinga kakhulu. Ngaphezu kwalokho, abakhi bepakethe bangaqinisekisa nge-IEC 62619 kanye ne-UL 9540A ukuthi balawula ukusabalala.
2.Amandla Okukhipha Okujulile(I-1965)I-DoD）
Ngokuphathelene ne-DoD, amabhethri elanga e-LiFePO4 abonisa inzuzo esobala, engafinyelela i-DoD ezinzile engu-80%-95% ngaphandle kokulimala. I-DoD yamabhethri e-lead-acid ivame ukukhawulelwa ku-50% ukuvimbela ukonakala kwamandla okuhlala njalo ngenxa ye-plate sulfation.
Ngenxa yalokho, i-a10kWhuhlelo lokugcina amandlaUkusebenzisa ubuchwepheshe be-LiFePO4 kunganikeza amandla angasetshenziswa angu-8-9.5kWh, kuyilapho uhlelo lwe-lead-acid lunganikeza cishe ama-5kWh kuphela.
3.Isikhathi Sokuphila kanye Nomthamo Womjikelezo
Izindleko zokutshalwa kwezimali kobuchwepheshe be-LiFePO4 zizoletha imbuyiselo ngesikhathi eside sokuphila komkhiqizo. Ezine-lead-acid zivame ukwehla ngokushesha ekusebenzeni ngemva kwemijikelezo engu-300-500 kuphela yokusetshenziswa kakhulu.
Kodwa amabhethri e-LiFePO4 anikeza impilo yomjikelezo ojulile odlula imijikelezo engu-6,000 (ngaphezu kuka-80% DoD). Ngisho nangomjikelezo owodwa wokushaja nokukhipha ishaja ngosuku, angasebenza kahlekuya kuIminyaka eyi-15.
4.Ubuningi Bamandla
Ubuningi bamandla di-efineukuthi ibhethri lingagcina amandla angakanani ngevolumu noma isisindo esithile. Ubuningi bamandla bamabhethri elanga e-LiFePO4 buphakeme kakhulu. Ngenxa yobukhulu obufanayo, anosayizi omncane nesisindo esilula, okusindisa ngempela isikhala sokufaka futhi kwenza kube lula ukuthutha.
5.Ukusebenza Kahle Kokushaja
Ukusebenza kahle kwebhethri lelanga le-LiFePO4 ukuya nokubuya kungu-92-97%. Amabhethri e-lead-acid awasebenzi kahle kangako, kanti ukusebenza kahle kokuhamba nokubuya cishe kungu-70-85%. Kuwo wonke ama-kWh ayi-10 abanjwe, izinhlelo ze-lead-acid ziguqula u-15-25% wamandla elanga abe yimfucuza yokushisa. Futhi ukulahlekelwa kwebhethri le-LFP kungu-0.3-0.8 kWh kuphela.
6.Izidingo Zokunakekela
Fnoma amabhethri e-lead-acid agcwele amanzi, ukulungiswa ihlanganisaukuhlolwa njalo kwamazinga e-electrolyte kanye nokuvimbela ukugqwala kokugcina.
Amabhethri elanga e-LiFePO4 awadingi ukunakekelwa, okungadingiaukuhlanza amanzi okuhleliwe noma kwe-terminal, noma ukulungiswa kwezindleko zokulinganisa.
7.Izindleko Zokuqala vs. Izindleko Zomjikelezo Wokuphila
Izindleko zangaphambili zamabhethri e-LiFePO4 ziphakeme ngempela.I-FePOUhlelo lwe-PV olungaphandle kwegridi olune lukhombisa izindleko ezingcono zobunikazi. Bangakwazizigcina isikhathi eside sokusebenza futhi zidinga ukulungiswa okuncane ngenkathi zifinyelela ukusebenza kahle kwamandla okuphezulu. Imiphumela yesikhathi eside yalokhu kutshalwa kwezimali iholela ekulethweni kwenani eliphelele eliphezulu.
8.Ibanga Lokushisa Elibanzi
Amabhethri e-lead-acid abhekana nokwehla kokusebenza kwawo lapho esebenza ezindaweni ezibandayo zokushisa. Amabhethri elanga e-LiFePO4 anobubanzi bokushisa bokusebenza obubanzikusukela-20°C kuya ku-60°C.
9.Ubungane Kwemvelo Nokuzinza
Amabhethri elanga e-LiFePO4 awaqukethe izinsimbi ezisindayo njenge-lead, okuyintoziyingozi ku-imvelo futhi idinga izindlela ezikhethekile neziyinkimbinkimbi zokuvuselela. I-electrolyte esetshenziswa kumabhethri e-lead-acid yi-sulfuric acid, eyonakalisa futhi engabangela ukusha okukhulu. Ukuchitheka noma ukuvuza kungenza inhlabathi namanzi kube yi-acid, kulimaze izitshalo kanye nezinto eziphilayo zasemanzini.
Mangaki Amabhethri Elanga E-LiFePO4 Owadingayo
Ukunquma umthamo webhethri kuyisinyathelo esibalulekile ekwakhiweni kwesistimu yelanga engaphandle kwegridi. Ake sihambe ngesibonelo ukuze sibone ukuthi kwenziwa kanjani:
(1) Izinkolelo:
Ukusetshenziswa Kwamandla Kwansuku Zonke: 5 kWh
Izinsuku Zokuzimela: Izinsuku ezi-2
I-DoD Engasetshenziswa Yebhethri: 90% (0.9)
Ukusebenza Kahle Kwesistimu: 95% (0.95)
l I-Voltage Yesistimu: 48V
Ibhethri Elilodwa Elikhethiwe: 5.12 kWh Ibhethri Lelanga le-ROYPOW LiFePO4
(2) Inqubo Yokubala:
l Isidingo Esiphelele Sokugcina = 5 kWh/ngosuku × izinsuku ezi-2 = 10 kWh
l Ingqikithi Yomthamo Webhange Lebhethri = 10 kWh ÷ 0.9 ÷ 0.95 ≈ 11.7 kWh
l Inani Lamabhethri = 11.7 kWh÷ 5.12 kWh = amabhethri angu-2.28
Isiphetho: Njengoba amabhethri engeke athengwe ngawodwana, udinga amabhethri amathathu kulawa, nawo anikeza isilinganiso esikhulu sokuphepha esingaphezu kwesidingo sakho sokuqala sama-kWh ayi-10.
Ezinye Izinto Okufanele Uzicabangele Lapho Ukhetha Ibhethri Lelanga le-LiFeO4
üUkuhambisana Kwesistimu:Qondanisa i-voltage yebhethri engaphandle kwegridi ne-inverter/ishaja yakho, bese usebenzisa isilawuli esinephrofayili yokushaja ye-LFP. Ungashaji ngaphansi kuka-0 °C, kanye nokuhlola ukushaja okuphezulu kwebhethri kanye nomthamo wokukhipha amandla ngokumelene nosayizi we-inverter yakho.
üUkukwazi Ukukhula Kwesikhathi Esizayo kanye Nomklamo We-Modular:Hlela ukwengeza umthamo ngamamojula afanayo. Faka ucingo nge-busbars ukuze intambo ngayinye ibone ubude bendlela obufanayo, bese ulinganisa ama-voltage ngaphambi kokulinganisa ukuze ugweme ukungalingani. Landela uchungechunge lomenzi kanye nemikhawulo efanayo.
üUmkhiqizo kanye newaranti:Kufanele ufune amagama alula, njengeminyaka ehlanganisiwe, imikhawulo yokudlula komjikelezo/amandla, kanye nomthamo wokuphela kwewaranti. Ngaphandle kwalokho, izinhlobo ezinezitifiketi zokuphepha (IEC 62619 kanye ne-UL 1973) kanye nokusekelwa kwesevisi yendawo kufanele kukhethwe.
Amabhethri Elanga e-ROYPOW Lithium-iron
Amabhethri ethu elanga e-ROYPOW lithium-iron anikeza isikhathi eside sokuphila kanye nezinketho zokuklama eziguquguqukayo, kanye nezindleko zokusebenza ezincishisiwe., okuyizixazululo ezifanele kakhulu ze-ramakhabhini e-emotetoizinhlelo zelanga ezingaphandle kwegridi yezindlu. Thatha ezethuIbhethri Elifakwe Odongeni Elingu-11.7kWhnjengesibonelo:
- Isebenza kumaseli e-LiFePO4 ebanga A, iqinisekisa ukusebenza okuphephile ngamazinga aphezulu okusebenza.
- Inemijikelezo engaphezu kuka-6,000, igcina ukusebenza okuthembekile iminyaka eyishumi.
- Ibhethri ivumela abasebenzisi ukuthi baxhume amayunithi afinyelela kwangu-16 ngesikhathi esisodwa ukuze banikeze amandla aguquguqukayo.
- It'iyahambisana nemikhiqizo ehamba phambili ye-inverter ukuqinisekisa isipiliyoni sokusekela amandla esingenamthungo.
- Isekela ukucushwa kwekheli lokushintsha i-DIP okuzenzakalelayo ukuze kube lula ukusethwa.
- Ibhethri lisekela ukuqapha okukude kwesikhathi sangempela kanye nokuthuthukiswa kwe-OTA nge-ROYPOW App.
- Isekelwa yiwaranti yeminyaka eyi-10 yokuthula kwengqondo.
Ukuze sizivumelanise kahle nezindawo ezahlukene zokufaka nezidingo zamandla, siphinde sinikeze5kWh ifakwe odongeni, 16kWhukuma phansi,futhi5kWhamabhethri elanga afakwe erekhi ohlelweni lwakho olungaphandle kwegridi.
Ukulungeleai-chieveti-rueeukungezwani komzimbaiukuzimela ne-ROYPOWXhumana nochwepheshe bethu ukuze uthole ukubonisana kwamahhala.
