Nrog rau txoj kev loj hlob sai ntawm lub zog tauj dua tshiab, suav tsis txheeb manufacturers thiab lwm tus neeg ntawmLiFePO4 roj teebtau tshwm sim hauv Suav teb. Txawm li cas los xij, qhov zoo ntawm cov tuam ntxhab no txawv heev. Yog li, koj yuav ua li cas thiaj paub tseeb tias cov roj teeb hauv tsev koj yuav yog ua nrog Qib A LiFePO4 Cells?
Hauv Suav teb, LiFePO4 hlwb feem ntau muab faib ua tsib qib:
- QIB A+
- QIB A-
– QIB B
– QIB C
– SECOND-HAND
GRADE A + thiab GRADE A- raug suav tias yog Qib A LiFePO4 Cells. Txawm li cas los xij, GRADE A- qhia tau hais tias kev ua haujlwm qis dua me ntsis ntawm tag nrho lub peev xwm, kev sib luag ntawm tes, thiab kev tiv thaiv sab hauv.
Yuav txheeb xyuas LiFePO4 Cells li cas?
Yog tias koj yog ib tus neeg muab khoom siv hnub ci lossis tus neeg teeb tsa ua haujlwm nrog lub chaw tsim khoom roj teeb tshiab, koj tuaj yeem txiav txim siab sai sai seb tus neeg muab khoom puas muab qib A LiFePO4 Cells rau koj? Ua raws li cov kauj ruam no, thiab koj yuav tau txais qhov txuj ci tseem ceeb no sai sai.
Kauj Ruam 1: Ntsuam xyuas lub zog ceev ntawm cov Cells
Cia peb pib los ntawm kev sib piv lub zog ceev ntawm 3.2V 100Ah LiFePO4 hlwb los ntawm tsib lub zog cia roj teeb manufacturers hauv Suav teb:
| Hom | Qhov hnyav | Specification | Muaj peev xwm | Zog Ceev |
| EVE | 1, 98kg | 3.2V 100Ah | 320 wb | 161 Wh/kg |
| REPT | 2.05kg ib | 3.2V 100Ah | 320 wb | 150 Wh/kg |
| CATL | 2, 27kg | 3.2V 100Ah | 320 wb | 140 Wh/kg |
| BYD | 1, 96kg | 3.2V 100Ah | 320 wb | 163 Wh/kg |
TSWV YIM: Zog Ceev = Peev Xwm / Nyhav
Los ntawm cov ntaub ntawv no, peb tuaj yeem txiav txim siab tias Qib A LiFePO4 Cells los ntawm cov tuam txhab ua lag luam muaj lub zog ntom ntom ntawm 140Wh / kg. Feem ntau, 5kWh cov roj teeb hauv tsev yuav tsum muaj 16 lub hlwb, nrog rau cov roj teeb uas hnyav li 15-20kg. Yog li, tag nrho qhov hnyav yuav yog:
| Hom | Cell Luj | Lub thawv hnyav | Specification | Muaj peev xwm | Zog Ceev |
| EVE | 31, 68 kq | 20kg ua | 51.2V 100Ah | 5120 wb | 99.07 Wh/kg |
| REPT | 32,8kg :ua | 20kg ua | 51.2V 100Ah | 5120 wb | 96,96 Wh/kg |
| CATL | 36.32kg 3 | 20kg ua | 51.2V 100Ah | 5120 wb | 90.90 Wh/kg |
| BYD | 31.36 Kg | 20kg ua | 51.2V 100Ah | 5120 wb | 99,68 Wh/kg |
Tswv yim: Zog Ceev = Peev Xwm / (Cell yuag + Box hnyav)
Hauv lwm lo lus, a5 kWh roj teeb hauv tsevsiv Qib A LiFePO4 Cells yuav tsum muaj lub zog ceev ntawm yam tsawg 90.90Wh / kg. Raws li cov lus qhia tshwj xeeb ntawm BSLBATT's Li-PRO 5120 qauv, lub zog ceev yog 101.79Wh / kg, uas sib haum nrog cov ntaub ntawv rau EVE thiab REPT hlwb.
Kauj Ruam 2: Ntsuas qhov hnyav ntawm cov cell
Raws li cov ntaub ntawv los ntawm plaub lub tuam txhab ua lag luam, qhov hnyav ntawm ib leeg 3.2V 100Ah Qib A LiFePO4 ntawm tes yog kwv yees li 2kg. Los ntawm qhov no, peb tuaj yeem xam:
- Lub 16S1P 51.2V 100Ah roj teeb yuav hnyav 32kg, ntxiv rau qhov hnyav ntawm ib ncig ntawm 20kg, rau tag nrho qhov hnyav ntawm 52kg.
- Lub roj teeb 16S2P 51.2V 200Ah yuav hnyav 64kg, ntxiv rau qhov hnyav ntawm ib ncig ntawm 30kg, rau tag nrho qhov hnyav ntawm 94kg.
(Ntau lub tuam txhab tam sim no ncaj qha siv 3.2V 200Ah hlwb rau 51.2V 200Ah roj teeb, xws li BSLBATT'sLi-PRO 10240. Lub hauv paus ntsiab lus suav tseem zoo ib yam.)
Yog li, thaum tshuaj xyuas cov lus hais, ua tib zoo mloog cov roj teeb hnyav uas muab los ntawm cov chaw tsim khoom. Yog tias lub roj teeb hnyav dhau lawm, cov hlwb siv yuav muaj qhov tsis txaus ntseeg thiab tsis yog Qib A LiFePO4 Cells.
Nrog rau kev tsim cov tsheb hluav taws xob ntau, ntau lub roj teeb EV so haujlwm tau rov ua dua rau lub zog cia. Cov hlwb no feem ntau tau dhau ntau txhiab lub voj voog, txo qis lub voj voog lub neej thiab lub xeev kev noj qab haus huv (SOH) ntawm LiFePO4 hlwb, muaj peev xwm tawm ntawm 70% lossis tsawg dua ntawm lawv cov peev txheej qub. Yog tias cov xov tooj thib ob siv los tsim cov roj teeb hauv tsev, ua tiav ib yam10 kWh lub peev xwm yuav xav tau ntau lub hlwb, ua rau lub roj teeb hnyav dua.
Los ntawm kev ua raws li ob kauj ruam no, koj yuav tuaj yeem dhau los ua tus kws tshaj lij roj teeb uas tuaj yeem paub meej tias koj lub roj teeb puas tsim nrog Qib A LiFePO4 Cells, ua cov qauv no tshwj xeeb tshaj yog rau cov khoom siv hnub ci distributors lossis cov neeg siv khoom nruab nrab.
Tau kawg, yog tias koj yog ib tus kws tshaj lij hauv kev siv hluav taws xob txuas ntxiv nrog kev nkag mus rau cov khoom siv roj teeb, koj tuaj yeem ntsuas lwm yam kev ntsuas xws li kev muaj peev xwm, kev tiv thaiv sab hauv, tus nqi tawm ntawm tus kheej, thiab lub peev xwm rov qab los txiav txim siab qib ntawm tes.
Cov Lus Qhia Kawg
Raws li lub zog cia kev lag luam txuas ntxiv nthuav dav, ntau thiab ntau lub npe thiab cov tuam ntxhab yuav tshwm sim. Thaum xaiv tus neeg muag khoom, nco ntsoov ceev faj ntawm cov uas muab cov nqi qis qis lossis cov tuam txhab tsim tshiab, vim tias lawv yuav ua rau muaj kev pheej hmoo rau koj txoj kev lag luam. Qee cov neeg muag khoom kuj tseem siv Qib A LiFePO4 Cells los tsim cov roj teeb hauv tsev tab sis ua rau lub peev xwm loj dua. Piv txwv li, lub roj teeb ua nrog 3.2V 280Ah hlwb uas tsim 51.2V 280Ah roj teeb yuav muaj peev xwm ntawm 14.3kWh, tab sis tus neeg muag khoom yuav tshaj tawm nws li 15kWh vim tias lub peev xwm nyob ze. Qhov no tuaj yeem ua rau koj xav tias koj tau txais 15kWh roj teeb ntawm tus nqi qis, thaum qhov tseeb, nws tsuas yog 14.3kWh.
Xaiv tus neeg muag khoom siv roj teeb hauv tsev uas txhim khu kev qha thiab kev tshaj lij yog ib txoj haujlwm nyuaj. Nrog ntau yam kev xaiv muaj, nws yooj yim rau kev ntxhov siab. Tias yog vim li cas peb pom zoo kom nrhiavBSLBATT, ib lub chaw tsim khoom nrog ntau tshaj 20 xyoo ntawm kev paub hauv kev lag luam roj teeb. Txawm hais tias peb cov nqi yuav tsis yog qhov qis tshaj, peb cov khoom zoo thiab cov kev pabcuam tau lees tias yuav tawm mus ntev. Qhov no yog hauv paus hauv peb lub hom phiaj kev pom: los muab cov kev daws teeb meem zoo tshaj plaws lithium roj teeb, uas yog vim li cas peb ib txwm hais kom siv Qib A LiFePO4 Cells.
