High-voltage lithium roj teebyog lub zog cia roj teeb uas paub txog qhov muaj zog DC cov zis ntawm lub cev los ntawm kev sib txuas ntau lub roj teeb hauv series. Nrog rau qhov kev thov loj zuj zus ntxiv rau lub zog tauj dua tshiab, thiab tib neeg txoj kev tsom mus rau kev nyab xeeb thiab muaj txiaj ntsig ntawm kev hloov pauv ntawm lub hnub ci zog, cov roj teeb lithium high-voltage tau dhau los ua ib qho ntawm cov khoom siv hluav taws xob nrov tshaj plaws hauv kev ua lag luam.
Nyob rau hauv 2024, cov qauv ntawm high-voltage tsev cia system yog pom tseeb, ib tug xov tooj ntawm lub zog cia roj teeb manufacturers thiab cov hom tau launched ib tug ntau yam ntawm high-voltage lithium hnub ci roj teeb, cov roj teeb no tsis tsuas yog nyob rau hauv lub peev xwm, lub voj voog lub neej thiab lwm yam. ib qho tseem ceeb ntawm kev tawg, tab sis kuj nyob rau hauv kev nyab xeeb thiab kev tswj xyuas ntse txuas ntxiv txhim kho. Hauv tsab xov xwm no, peb yuav muab koj cov ntsiab lus ntawm qee qhov zoo tshaj plaws high-voltage lithium roj teeb hauv xyoo 2024, los pab koj xaiv qhov zoo dua.roj teeb hauv tsevbackup system uas zoo tshaj plaws suits koj xav tau kev pab.
Standard 1: Siv tau roj teeb muaj peev xwm
Cov roj teeb muaj txiaj ntsig yog hais txog lub zog uas koj tuaj yeem them rau hauv lub roj teeb rau tom qab siv hauv tsev. Hauv peb 2024 kev sib piv ntawm high-voltage lithium roj teeb, lub kaw lus cia muab lub peev xwm muaj txiaj ntsig zoo tshaj plaws yog Sungrow SBH roj teeb nrog 40kWh, ua raws li los ntawm kev sib tw.BSLBATT MatchBox HVSroj teeb nrog 37.28 kWh.
Txuj 2: Lub Zog
Lub hwj chim yog tus nqi hluav taws xob koj lub roj teeb Li-ion tuaj yeem xa tau txhua lub sijhawm; Nws ntsuas hauv kilowatts (kW). Los ntawm kev paub txog lub hwj chim, koj tuaj yeem paub cov xov tooj ntawm cov khoom siv hluav taws xob uas koj tuaj yeem ntsaws rau txhua lub sijhawm. Nyob rau hauv 2024 high-voltage lithium-ion roj teeb kev sib piv, BSLBATT MatchBox HVS ib zaug ntxiv sawv tawm ntawm 18.64 kW, ntau dua li ob npaug ntawm Huawei Luna 2000, thiab BSLBATT MatchBox HVS tuaj yeem ncav cuag lub zog siab tshaj ntawm 40 kW rau 5s. .
Standard 3: Round-trip Efficiency
Round-trip efficiency yog hais txog qhov sib piv ntawm lub zog koj xav tau los them lub roj teeb thiab lub zog muaj zog thaum koj tso tawm. Nws yog li ntawd hu ua "round-trip (rau roj teeb) thiab rov qab (los ntawm roj teeb) efficiency". Qhov sib txawv ntawm ob qhov no yog vim qhov tseeb tias ib txwm muaj qee lub zog poob hauv kev hloov hluav taws xob los ntawm DC rau AC thiab rov ua dua; qhov poob qis dua, lub roj teeb Li-ion yuav ua tau zoo dua. Nyob rau hauv peb 2024 kev sib piv ntawm high-voltage lithium roj teeb, BSLBATT MatchBOX thiab BYD HVS ranked thawj nrog 96% efficiency, raws li Fox ESS ESC thiab Sungrow SPH ntawm 95%.
Txheem 4: Zog Ceev
Feem ntau hais lus, lub teeb lub roj teeb thiab qhov chaw tsawg nws yuav siv sij hawm, qhov zoo dua, thaum tuav tib lub peev xwm. Txawm li cas los xij, feem ntau high-voltage LiPoPO4 roj teeb tau muab faib ua cov qauv uas nws qhov loj thiab qhov hnyav tuaj yeem ua tau yooj yim los ntawm ob tus neeg; los yog qee zaum txawm los ntawm ib tus neeg.
Yog li ntawm no peb feem ntau sib piv lub zog loj ntawm txhua lub zog hluav taws xob lithium roj teeb hom, roj teeb lub zog loj yog hais txog lub peev xwm ntawm lub roj teeb los khaws lub zog (tseem hu ua lub zog tshwj xeeb), uas yog qhov piv ntawm tag nrho lub zog khaws cia hauv lub roj teeb rau nws tag nrho cov huab hwm coj, piv txwv li, Wh / kg, uas qhia txog qhov loj ntawm lub zog uas tuaj yeem muab tau rau ib chav tsev ntawm qhov loj ntawm lub roj teeb.Kev suav cov mis: lub zog ceev (wh/Kg) = (capacity * voltage) / mass = (Ah * V) / kg.
Lub zog ceev yog siv los ua ib qho tseem ceeb rau kev ntsuas kev ua haujlwm ntawm cov roj teeb. Feem ntau hais lus, lub zog siab ceev lithium-voltage roj teeb muaj peev xwm khaws ntau lub zog nyob rau hauv tib qhov hnyav lossis ntim, yog li muab lub sijhawm ua haujlwm ntev lossis ntau yam rau cov khoom siv. Los ntawm kev suav thiab kev sib piv, peb pom tias Sungrow SBH muaj lub zog siab ceev ntawm 106Wh / kg, ua raws li BSLBATT MacthBox HVS, uas kuj muaj lub zog ceev ntawm 100.25Wh / kg.
Txheem 5: Scalability
Lub scalability ntawm koj lub zog cia system tso cai rau koj kom muaj peev xwm ntawm koj Li-ion roj teeb nrog modules tshiab yam tsis muaj teeb meem thaum koj xav tau lub zog loj hlob. Yog li ntawd, nws yog ib qho tseem ceeb kom paub tias lub peev xwm ntawm koj qhov system cia yuav nthuav dav mus rau yav tom ntej.
Nyob rau hauv kev sib piv ntawm high-voltage lithium roj teeb nyob rau hauv 2024, lub BSLBATT MatchBox HVS muaj qhov zoo tshaj plaws versatility nyob rau hauv cov nqe lus ntawm scalable muaj peev xwm, mus txog rau 191.4 kWh, raws li los ntawm lub Sungrow SBH nrog ib tug scalable peev ntawm 160kWh.
Qhov no, muab hais tias peb tab tom xav txog cov roj teeb uas tuaj yeem txuas nrog ib qho inverter. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias feem ntau cov tuam txhab roj teeb tso cai rau ntau lub inverters los nruab rau tib lub sijhawm, yog li tseem nthuav dav tag nrho cov peev txheej ntawm lub zog cia.
Standard 6: Backup and Off-grid Applications
Thaum lub sijhawm muaj zog tsis ruaj khov thiab kev hem thawj ntawm lub ntiaj teb hluav taws xob hluav taws xob, ntau thiab ntau tus neeg xav kom lawv cov cuab yeej muaj peev xwm tiv thaiv cov xwm txheej tsis tau pom dua. Yog li ntawd, muaj cov ntawv thov xws li hluav taws xob thaum muaj xwm txheej ceev lossis thaub qab, lossis muaj peev xwm ua haujlwm off-grid thaum muaj hluav taws xob poob, yog qhov tseem ceeb heev.
Hauv peb 2024 kev sib piv ntawm high-voltage lithium roj teeb, tag nrho cov muaj xwm txheej ceev los yog backup outputs, thiab Nws kuj muaj peev xwm txhawb kev sib txuas ntawm kab hluav taws xob los yog off-grid lag luam.
Txheem 7: Qib Kev Tiv Thaiv
Cov neeg tsim khoom ntawm lub zog cia tshuab nthuav tawm lawv cov khoom rau ntau qhov kev sim los ua kom pom lawv txoj kev tiv thaiv ntau yam ntawm ib puag ncig.
Piv txwv li, hauv peb 2023 kev sib piv ntawm high-voltage lithium roj teeb, peb (BYD, Sungrow, thiab LG) muaj IP55 tiv thaiv qib, thiab BSLBATT muaj IP54 tiv thaiv qib; qhov no txhais tau hais tias, thaum tsis muaj dej, plua plav tsis tuaj yeem cuam tshuam nrog kev ua haujlwm zoo ntawm cov cuab yeej thiab tseem tiv thaiv dej ntawm ib qho tshwj xeeb siab; qhov no tso cai rau lawv los nruab rau hauv lub tsev lossis hauv chaw nres tsheb lossis lub tsev.
Lub roj teeb uas sawv tawm hauv qhov kev ntsuas no yog Huawei Luna 2000, uas muaj qhov ntsuas IP66 tiv thaiv, ua rau nws tsis muaj plua plav thiab lub dav hlau dej muaj zog.
Txheem 8: Warranty
Lub warranty yog ib txoj hauv kev rau cov chaw tsim khoom los qhia tias nws muaj kev ntseeg siab hauv nws cov khoom, thiab nws tuaj yeem muab peb cov lus qhia txog nws qhov zoo. Hauv qhov no, ntxiv rau xyoo warranty, nws tseem ceeb heev kom nco ntsoov tias lub roj teeb yuav ua haujlwm zoo npaum li cas tom qab xyoo ntawd.
Hauv peb 2024 kev sib piv ntawm high-voltage lithium roj teeb, txhua tus qauv muab 10 xyoo warranty. Tab sis, LG ESS Flex, sawv ntawm tus so, muab 70% kev ua tau zoo tom qab 10 xyoo; 10% ntau dua lawv cov neeg sib tw.
Fox ESS thiab Sungrow, ntawm qhov tod tes, tseem tsis tau tshaj tawm cov txiaj ntsig EOL tshwj xeeb rau lawv cov khoom.
