Li-Ion thev naus laus zis: chav tsev nqi poob sai dua li kev kwv yees

Nyob zoo dua, cov phooj ywg!

Kab lus "Lub sijhawm ntawm lithium-ion UPS: hluav taws kub hnyiab lossis ib kauj ruam nyab xeeb rau yav tom ntej?"Peb tau kov txog qhov teeb meem ntawm tus nqi kwv yees ntawm Li-Ion kev daws teeb meem (cov khoom siv cia, roj teeb) hauv cov ntsiab lus tshwj xeeb - $ / kWh. Tom qab ntawd qhov kev kwv yees rau xyoo 2020 yog $ 200 / kWh. Tam sim no, raws li tau pom los ntawm CDPV, tus nqi ntawm lithium tau poob qis dua $ 150 thiab poob qis dua $ 100 / kWh tau kwv yees (raws li Forbes). Qhov no hloov li cas, koj nug? Ua ntej tshaj plaws, qhov sib txawv ntawm tus nqi ntawm cov roj teeb classic thiab cov thev naus laus zis zoo, nrog rau cov kev daws teeb meem raws li lawv, tau raug txo. Cia peb sim xam raws li qhov xwm txheej ntawm tib lub nkoj hauv Nyij Pooj nrog Li-Ion roj teeb.

Cov ntaub ntawv los ntawm cov ntaub ntawv

Peb muab raws li thawj cov ntaub ntawv:

• tus nqi kwv yees ntawm 200 $ / kWh los ntawm peb tsab xov xwm hais txog kev nyab xeeb hluav taws ntawm lithium
• tus nqi kwv yees ntawm 300 $ / kWh los ntawm peb tsab xov xwm 2018 "UPS thiab roj teeb array ..."
• Qhov kwv yees tus nqi sib txawv ntawm VRLA thiab Li-Ion cov kev daws teeb meem yog 1,5-2 zaug, coj los ntawm peb tsab xov xwm 2018 ntawm kev phom sij ntawm lithium.

Tam sim no cia peb suav

1. Qhov kev kwv yees poob qis hauv tus nqi ntawm cov tsav tsheb tau ceev faj heev; qhov tseeb poob qis dua sai dua
2. Kev tsav tsheb tom qab tus nqi poob ntawm cov kev daws teeb meem kev lag luam uas siv cov roj teeb lithium-ion yog lub tsheb hluav taws xob: lub zog ceev hauv lub roj teeb tau nce, kev hloov pauv hloov, thiab kev tsim khoom tau loj hlob sai. Koj tuaj yeem nyeem ntxiv hauv "Tus sau tshuaj xyuas ntawm no"
3. Qhov kwv yees roj teeb muaj peev xwm ntawm Japanese submarine yog 17 MWh; peb coj tus nqi ntawm lithium rau xyoo 2017 ntawm tus nqi ntawm $ 300 / kWh. Peb tau txais 5,1 lab daus las.
4. Raws li tus nqi tiag tiag los ntawm CDPV, qhov poob qis yog kwv yees li 2% dhau 30 xyoos. Ntawm 2019 tus nqi, peb tau txais nyiaj khaws cia li ntawm $ 1,5 lab. Tsis phem huh? Kuv xav tias thaum tsim cov nkoj zoo li no, nws yuav tsum thauj nws nrog Li-Ion roj teeb thaum lub sijhawm kawg, ua ntej mus rau kev sim dej hiav txwv.
5. Nws tuaj yeem xav tias rau cov kev daws teeb meem ntawm cov roj teeb lithium, qhov poob ntawm tus nqi, nyeem tus nqi sib npaug nrog cov hmoov lead-acid roj teeb arrays, tau tshwm sim sai dua li qhov xav tau. Hauv ib tsab xov xwm 2018, qhov kwv yees qhov sib txawv ntawm UPS ntawm cov roj teeb lithium yog 1,5-2 npaug kim dua li UPS classic. Tam sim no, qhov sib txawv no yuav tsum muaj lub hom phiaj me dua ...
