Nkag siab txog roj teeb Cycle Life:
2000, 6000, thiab 12000 Cycles
Nyob rau hauv lub evolving sai heev sectors ntawmChaw nyobZog Cia System(ESS)thiabCommercial & Industrial (C&I) Cia, lub voj voog lub neej feem ntau yog thawj qhov ntsuas siv los txiav txim siab roj teeb zoo. Txawm hais tias daim ntawv cog lus cog lus 2,000, 6,000, lossis txawm tias 12,000 lub voj voog, cov lej no sawv cev rau tag nrho lub zog ntawm lub roj teeb tuaj yeem txav mus rau hauv thiab tawm ua ntej nws lub peev xwm poob qis dua ib qho kev qhia tshwj xeeb-feem ntau yog 80% ntawm nws thawj lub xeev (End of Life).
Txawm li cas los xij, lub voj voog siab suav rau ntawm daim ntawv tsis ib txwm txhais ncaj qha mus rau xyoo hauv daim teb. Piv txwv li, 6,000-lub voj voog roj teeb siv txhua hnub nyob rau hauv lub tsev backup system theoretically kav ntev dua 15 xyoo. Thaum 12,000 lub voj voog tau dhau los ua tus qauv kev lag luam tshiab rau tus nqiLithium Hlau Phosphate (LFP)cov hlwb, nws yog ib qho tseem ceeb uas yuav tau saib cov nuj nqis no raws li kev ntsuas ntsuas es tsis tau lees paub tiag - hnub tas sij hawm ntiaj teb.
Lab Cycles vs. Real-Lub Neej Kev Pabcuam Ntiaj Teb
Muaj qhov sib txawv nruab nrab ntawmTested Cycle LifethiabLub neej ua haujlwm tiag. Hauv chav kuaj, cov roj teeb raug sim nyob rau hauv "zoo tagnrho" cov xwm txheej: qhov kub thiab txias, tus nqi tshwj xeeb / tso tawm, thiab lub sijhawm so tsis siv neeg. Cov kev ntsuam xyuas no yog tsim los thawb cov chemistry mus rau nws cov kev txwv nyob rau hauv ib puag ncig tswj los txiav txim siab theoretical siab tshaj plaws ntawm cov hlwb.
Lub luag haujlwm tseem ceeb ntawm Kev Ntsuas Cov Cai
Yuav kom sib piv 2,000-cycle roj teeb nrog 12,000-cycle ib, koj yuav tsum saibKev kuaj mob(Standard Test Conditions). Qhov tseem ceeb tshaj plaws metric yog qhovC- tus nqi, uas ntsuas qhov ceev ntawm kev them nqi thiab tawm. Ib qho kev sim ua ntawm 0.5C (2 teev rau kev them nqi / tso tawm) tsis tshua muaj kev ntxhov siab ntau dua li qhov ua ntawm 1C (1 teev). Yog tias cov chaw tsim khoom thov 12,000 lub voj voog, lawv yuav zoo li ntsuas ntawm 0.25C thiab tswj nruj nruj 25 degree.
Tsis tas li ntawd, lubQhov tob ntawm qhov tso tawm (DoD)yog qhov kawg variable. Feem ntau cov kws tshaj lij- qib ESS hom xeem ntawm 80% lossis 90% DoD. Yog tias lub tuam txhab lees paub qhov ntsuas lub voj voog tsis zoo, xyuas seb lawv puas kuaj ntawm tsuas yog 70% DoD, uas ua kom muaj tus lej. Rau B2B kev yuav khoom, xyuas kom meej tias covKub (25 degree), Cov av noo, thiabXaus- ntawm-Lub Neej (EOL) cov qauvyog tus qauv yog tib txoj hauv kev los ua "apples-rau-apples" sib piv ntawm cov kev daws teeb meem sib txawv.
