Li-Ion tekinoroji: mutengo weyuniti uri kudonha nekukurumidza kupfuura kufanotaura

Mhoro zvakare, shamwari!

Chinyorwa "Nguva ye lithium-ion UPS: njodzi yemoto kana nhanho yakachengeteka mune ramangwana?"Takabata pamusoro penyaya yemutengo wakatarwa weLi-Ion mhinduro (midziyo yekuchengetedza, mabhatiri) mune chaiyo mazwi - $/kWh. Zvino fungidziro ye2020 yaive $200/kWh. Iye zvino, sezvinogona kuonekwa kubva kuCDPV, mari ye lithium yakaderera pasi pe $ 150 uye kudonha nokukurumidza pasi pe $ 100 / kWh inofungidzirwa (maererano ne Forbes) Izvi zvinoshandura chii, iwe unobvunza? Chekutanga pane zvese, musiyano uripo pakati pemutengo wemabhatiri ekare uye anovimbisa tekinoroji, pamwe nemhinduro dzakabva pazviri, iri kuderedzwa. Ngatiedzei kuverenga pahwaro hwenyaya yeiyo imwe chete yeJapan submarine ine Li-Ion mabhatiri.

Data yekutanga

Isu tinotora se data yekutanga:

• mutengo we 200 $ / kWh kubva munyaya yedu pamusoro pekuchengetedzwa kwemoto kwe lithium
• mutengo wekufanotaura kwe300 $/kWh kubva kuchinyorwa chedu cha2018 "UPS uye bhatiri array ..."
• Iyo inofungidzirwa mutengo musiyano pakati peVRLA neLi-Ion mhinduro ndeye 1,5-2 nguva, yakatorwa kubva kuchinyorwa chedu che2018 panjodzi yemoto ye lithium.

Zvino ngativerengei

1. Kudzikira kwakafanotaurwa kwemutengo wemadhiraivha kwainyanya kungwarira; kuderera chaiko kuri kukurumidza
2. Simba rekufambisa kuseri kwemutengo unodonha wezvigadziriso zveindasitiri uchishandisa lithium-ion mabhatiri imotokari dzemagetsi: kuwanda kwesimba mubhatiri kuri kuwedzera, marongero ari kuchinja, uye kugadzirwa kuri kukura nekukurumidza. Unogona kuverenga zvakawanda mu "Munyori wongororo apa"
3. Iyo inofungidzirwa bhatiri remuzasi megungwa reJapan raive 17 MWh; isu tinotora mutengo weyuniti yelithium ye2017 muhuwandu hwe300/kWh. Tinowana mamiriyoni 5,1 emadhora.
4. Kana tikatanga kubva pamutengo chaiwo kubva kuCDPV, zvino kudonha kwaive kunenge 2% pamakore 30. Pamitengo ye2019, tinowana mari yemadhora anenge mamiriyoni 1,5. Hazvina kuipa huh? Ini ndinofunga kana uchivaka mabhoti akadai, zvinofanirwa kuakurisa neLi-Ion mabhatiri panguva yekupedzisira, pamberi chaipo kuenda kumiyedzo yegungwa.
5. Zvinogona kufungidzirwa kuti kune zvigadziriso zveindasitiri pamabhatiri eti lithium, kudonha kwemutengo, kuverenga mutengo kuenzana nelead-asidhi bhatiri arrays, zviri kuitika nekukurumidza kupfuura zvinotarisirwa. Muchinyorwa cha2018, musiyano unofungidzirwa pakati peUPS pamabhatiri e lithium waive 1,5-2 nguva inodhura kupfuura yekare UPS. Parizvino, gap iri rinofanira kunge riri diki ...

… zvichaenderera mberi…
