A 48V 100Ah LiFePO4 roj teebkhw muag khoom kwv yees4.8-5.12 kWhntawm lub zog thiab feem ntau yog siv rau hnub ci cia, xov tooj thaub qab, RV thiab marine fais fab, tawm -daim phiaj cabins, thiab cov khoom lag luam me me. Txawm hais tias nws yog lub roj teeb tsim nyog rau koj qhov project yog nyob ntawm daim ntawv lo "48V 100Ah" thiab ntau dua ntawm kev ntsuas roj teeb (BMS) tam sim no, kev sib txuas lus raws tu qauv, kev khiav hauj lwm kub, kev ntsuas lub neej, thiab cov ntawv pov thawj.
Cov lus qhia no piav qhia lub zog npaum li cas lub roj teeb tau xa tawm, yuav ua li cas kwv yees lub sijhawm ua haujlwm rau cov khoom thauj tiag tiag, cov ntawv pov thawj thiab cov ntaub ntawv thov los ntawm cov neeg xa khoom, thiab thaum lub roj teeb 48V 100Ah LiFePO4 yogtsis yogqhov zoo tshaj plaws haum. Nws yog sau los ntawm qhov kev xav ntawm lub roj teeb system engineer txhawb B2B integrators thiab ib tus neeg siv.
Dab tsi yog 48V 100Ah LiFePO4 Roj teeb tiag tiag
Lub 48V 100Ah LiFePO4 roj teeb yog lithium hlau phosphate roj teeb pob nrog lub nominal voltage nyob rau hauv 48V chav kawm ntawv (feem ntau 51.2V rau 16- xov tooj configurations) thiab ib tug amp- teev ntsuam xyuas ntawm 100Ah. Nws yog tsim los rau cov ntawv thov sib sib zog nqus uas lub roj teeb tau rov ua dua thiab rov ua dua tshiab, tsis yog rau lub sijhawm luv luv ntawm qhov pib tam sim no.
Ob qhov tshwj xeeb txiav txim siab seb nws coj li cas hauv qhov system tiag tiag:
- Nominal voltage: "48V" yog chav kawm voltage. Qhov tseeb nominal voltage feem ntau yog 48V (15 hlwb × 3.2V) lossis 51.2V (16 hlwb × 3.2V). Charge voltage feem ntau zaum ntawm 54.4V thiab 58.4V nyob ntawm kev teeb tsa. Nco ntsoov xyuas cov ntaub ntawv tsis yog xav tias.
- Amp - teev muaj peev xwm: 100Ah piav qhia txog tus nqi ntawm lub roj teeb tuaj yeem xa tuaj raws li kev sim tshwj xeeb. Yog tias koj xav tau kev piav qhia tob dua ntawm Ah txhais li cas hauv kev xyaum, saib peb phau ntawv qhiaamp- teev ntsuas.
Yog vim li cas LiFePO4 yog Dominant Chemistry rau Chaw Nres Tsheb
Lithium hlau phosphate yog qhov zoo dua rau kev nyob ruaj khov thiab sib sib zog nqus- daim ntawv thov kev siv lub voj voog vim nws cov thermal stability thiab lub neej ntev nyob rau hauv kev tswj xyuas. Kev nyab xeeb tseem nyob ntawm qhov zoo ntawm tes, pob tsim, thiab BMS, tsis yog chemistry xwb. Cov txheej txheem kev nyab xeeb thoob ntiaj teb rau kev lag luam lithium roj teeb yogIEC 62619: Ua, uas txhais tau hais tias yuav tsum tau kuaj rau cov lithium hlwb thib ob thiab cov roj teeb uas siv rau hauv cov ntawv thov kev lag luam.
Lub Zog Muaj Peev Xwm Ntau npaum li cas 48V 100Ah Roj Teeb Khw?
Zog (Wh)=Voltage × Amp- teev. Muaj ob hom configurations:
- 48V × 100Ah =4,800 kWh (4.8 kWh)
- 51.2V × 100Ah =5,120 kWh (5.12 kWh)
Yog tias koj tsis paub meej tias kWh cuam tshuam li cas rau kW thaum ntsuas lub roj teeb tiv thaiv kev thauj khoom, peb piav qhia ntawmkW vs kWhtaug kev ntawm lej.
Runtime Calculation Formula
Lub peev xwm theoretical tsis zoo ib yam li lub sijhawm siv tau. Ib tug tswv yim formula:
Usable runtime (teev) ≈ Roj teeb Wh × Usable DoD × Inverter efficiency ÷ Load watts
Piv txwv li 90% usable qhov tob ntawm paug thiab 92% inverter efficiency ntawm 5.12kWh roj teeb (51.2V × 100Ah):
- 500W load: ≈ 5,120 × 0.9 × 0.92 ÷ 500 ≈ 8,5h ua
- 1,000W load: ≈ 4,2h ua
- 2,000W load: ≈ 2.1h ib
- 3,000 W load: ≈ 1.4h ua
Cov lej no yog kwv yees. Lub sijhawm ua haujlwm tiag tiag poob qis ntxiv thaum qhov ntsuas kub qis dua 0 degree, thaum cov khoom thauj muaj qhov nrawm nrawm (compressors, twj tso kua mis, lub cev muaj zog), thaum lub roj teeb muaj hnub nyoog, lossis thaum BMS txo cov paug tawm tam sim no los tiv thaiv pob.
Cov txiaj ntsig tiag tiag thiab cov xwm txheej lawv nyob ntawm
Lub Neej Ntev Ntev, Nrog Caveats
Zoo - ua LiFePO4 pob tuaj yeem xa 3,000 mus rau 6,000+ cycles, tab sis tus lej ntawd tsis muaj nuj nqis yam tsis muaj kev sim. Thaum tshawb xyuas cov ntaub ntawv, xyuas:
- Qhov tob ntawm kev tso tawm siv nyob rau hauv lub voj voog ntsuas (feem ntau 80% lossis 90%)
- Them thiab tso tawm tus nqi (feem ntau 0.5C lossis 1C)
- Kev ntsuas kub (feem ntau 25℃± 2 degree)
- Xaus - ntawm - kev ua neej nyob (feem ntau 70% lossis 80% ntawm cov peev txheej ntsuas)
Ob lub roj teeb tshaj tawm "6,000 cycles" tuaj yeem muaj qhov sib txawv ntawm lub neej kev pabcuam yog tias ib qho raug kuaj ntawm 0.2C / 25℃/ 80% DoD thiab lwm qhov ntawm 1C / 45℃/ 100% DoD.
Thermal stability thiab kev nyab xeeb
LiFePO4 tiv taus cov thermal khiav ntau dua li ntau cov npib tsib xee-raws lithium chemistry, uas yog vim li cas nws tseem nyob ruaj khov. Rau kev thauj mus los, cov hlwb thiab pob khoom yuav tsum dhau cov kev xeem uas tau teev tseg hauvUN Manual of Tests and Criteria Section 38.3. Rau lub zog cia tshuab xa tawm hauv North America, cov neeg yuav khoom feem ntau kuj xav tauUL 1973 thiab UL 9540 ntawv pov thawj.
Kev siv tau ntau dua li txhuas-Acid
Lead-acid roj teeb feem ntau txwv rau 50% DoD kom khaws lub voj voog lub neej. Ib pob LiFePO4 tuaj yeem ua haujlwm ntawm 80-90% DoD. Hauv cov ntsiab lus siv tau, 48V 100Ah LiFePO4 roj teeb xa txog 1.6–1.8 × lub zog siv tau ntawm 48V 100Ah lead-acid bank ua ntej yuav tsum tau them rov qab.
Xaiv lub roj teeb zoo rau txhua daim ntawv thov
Daim ntawv lo "48V 100Ah" yog tib yam nyob rau hauv daim ntawv thov, tab sis lub roj teeb txoj cai rau lub telecom txee tsis yog lub roj teeb zoo rau lub nkoj nkoj. Hauv qab no yog qhov tseem ceeb rau ib daim ntawv thov:
Hnub ci zog cia
Paub meej tias lub inverter lub roj teeb voltage qhov rais (feem ntau 44-58V), qhov yuav tsum tau kev sib txuas lus raws tu qauv (CAN los yog RS485 rau feem ntau hybrid inverters), thiab seb lub inverter hom yog nyob rau hauv lub roj teeb lub compatibility daim ntawv teev. Rau cov ntsiab lus ntawm qhov system topology, saibntawm -grid vs off-grid vs hybrid solar systems. Cov hnub ci loj loj tseem xav tau BMS txuas ntxiv them tam sim no kom dhau MPPT cov zis tam sim no.
Telecom Backup Fais Fab
Telecom sites khiav ntawm nominal -48V DC systems. A 48V 100Ah khib roj teeb siv rautelecom backup hwj chimxav tau kom phim cov txee qhov ntev (feem ntau 19-nti lossis ETSI 21-nti khib), txhawb SNMP lossis Modbus cov chaw taws teeb saib xyuas, thiab ua haujlwm thoob plaws qhov kub thiab txias tau ntsib nyob rau sab nraum zoov. Parallel scalability rau 4-16 units yog ib txwm.
RV thiab Marine Systems
Qhov tseem ceeb hloov mus rau kev tiv thaiv qhov thaiv (IP65+ rau marine), kev co tsis kam, daim ntawv cog lus, thiab kev sib raug zoo nrog lub charger onboard (alternator, DC-DC charger, lossis shore{2}}power charger). Ntau tus neeg siv RV khiav 12V lossis 24V systems - 48V roj teeb tsuas yog tsim nyog yog tias lub inverter, charger, thiab DC faib kuj yog 48V- ntsuas.
Tawm -Grid Cabins thiab Chaw Taws Teeb
Kev saib xyuas qis tseem ceeb ntawm no dua li lwm qhov. Txheeb xyuas qhov qis- qhov kub thiab txias tiv thaiv qhov pib thiab seb lub pob puas tau ua ke nrog tus kheej - cua sov. Them LiFePO4 qis dua 0℃yam tsis muaj cua sov ua rau lub hlwb puas lawm - ntxiv rau qhov no hauv peb phau ntawv qhialithium roj teeb kub ntau yam.
Kev lag luam thiab kev lag luam thaub qab
Ib lub roj teeb 48V 100Ah feem ntau me dhau rau cov chaw lag luam. Feem ntau cov haujlwm yuav tsum muaj cov tsev txhab nyiaj sib npaug lossis ib lub khib nyiab tshwj xeeb. Hauv qhov ntsuas no,siab -voltage roj teeb tshuab(200V–800V) feem ntau xa cov kev ua tau zoo dua thiab qis dua - ntawm - tus nqi qis dua -voltage stacks.
48V 100Ah LiFePO4 vs Lead-Acid: Qhov txawv qhov teeb meem
| Qhov xwm txheej | 48V 100Ah LiFePO4 | 48V 100Ah Lead{2}}Acid (AGM/GEL) |
|---|---|---|
| Lub zog siv tau (tus qauv) | ~ 4.3-4.6kWh ntawm 90% DoD | ~ 2.4 kWh ntawm 50% DoD |
| Lub neej voj voog (tus qauv, 80% DoD) | 3,000–6, 000+ cycles | 500-1,200 cycles |
| Qhov hnyav | 40-50 Kg | 140-180 Kg |
| Round -kev ua haujlwm zoo | ~95–98% | ~75–85% |
