Feem ntau, lub tsev a48V LiFePO4 roj teebpob yuav tsum tau 16 hlwb txuas nrog hauv series. Txawm hais tias lej, a15-cell series (15S)muaj nominal voltage ntawm raws nraim15*3.2v=48.0v, nyob rau hauv cov qauv kev lag luam rau kev siv hluav taws xob thiab lub hnub ci, a16-cell series (16S)configuration feem ntau yog siv. Nws lub nominal voltage yog16*3.2v=51.2v.
Txawm hais tias ob qho tib si hu ua "48V roj teeb,"16-series configuration yog tam sim no tus qauv. Qhov no yog vim feem ntau 48V inverters thiab cov khoom siv them nyiaj tau tsim los ua haujlwm zoo tshaj plaws nrog 51.2V system. Txawm tias thaum lub roj teeb yuav luag tag, lub pob 16S tuaj yeem tswj tau qhov hluav taws xob ntau dua, txo qhov yuav ua rau lub inverter qis -voltage ceeb toom.
Tus naj npawb ntawm cov hlwb hauv 48v lifepo4 roj teeb
| Kev teeb tsa | Nominal voltage | Them tag nrho (100%) | Tshem tawm - tawm (tsawg) | Kev lag luam xwm txheej |
| 15 Cells (15S) | 48.0V | 54.0V | 42.0V | Laus/Less Common |
| 16 Cells (16S) | 51.2V | 57.6V | 44.8V | Niaj hnub Standard |
15S vs 16S Configuration: Qhov twg zoo dua rau koj 48V LifePo4 roj teeb?
Rau48V LiFePO4 roj teeb tshuab, cov16S teeb tsa (51.2V)feem ntau suav hais tias yog qhov kev xaiv zoo dua thiab ntau dua, thaum 15S teeb tsa (48V) feem ntau pom muaj nyob rau hauv qee cov qauv qub txeeg qub teg lossis qis - cov nqi daws teeb meem.
Lub ntsiab kom zoo dua ntawm 16S configuration yog nyob rau hauv nws superior compatibility nrog uas twb muaj lawm inverters thiab them li. Standard 48V lead-acid roj teeb systems feem ntau ncav cuag 54V rau 56V thaum them tag nrho, whereas ib tug tag nrho them 16S LiFePO4 roj teeb mus txog kwv yees li 57.6V (3.6V ib cell).
Qhov ntau qhov hluav taws xob no zoo sib xws rau cov yam ntxwv ntawm kev them nyiaj ntawm cov hlau lead-acid roj teeb, tso cai rau cov inverter ua haujlwm tau zoo dua hauv lawv lub qhov rais qhov hluav taws xob zoo, yog li txo lub zog hloov pauv. Nyob rau hauv sib piv, ib tug 15S configuration muaj ib tug nominal voltage ntawm 48V, tab sis nws tag nrho them voltage tsuas yog nyob ib ncig ntawm 54V. Thaum lub sij hawm tso tawm tiag tiag, qhov hluav taws xob poob sai dua, uas tuaj yeem ua rau inverters ua rau qis -voltage tiv thaiv ntxov ntxov, tiv thaiv kev siv tag nrho ntawm lub roj teeb lub zog.
Los ntawm lub zog ceev thiab tus nqi- kev pom kev ua tau zoo, 16S system muaj ib lub xov tooj ntxiv ntxiv piv rau 15S system. Qhov no txhais tau hais tias rau tib lub peev xwm (Ah), 16S system tuaj yeem muab kwv yees li 6.7% ntau lub zog cia (Wh). Thaum lub kaw lus 15S me ntsis txo cov nqi kho vajtse los ntawm kev siv ib lub xov tooj tsawg dua, qhov siab dua qhov hluav taws xob ntawm 16S system txo qis qhov system tam sim no, txo cov cua sov cable thiab txhim kho tag nrho cov kav ntev thiab kev nyab xeeb.
Feem ntau cov neeg siv khoom siv hluav taws xob khib nyiab roj teeb thiab lub zog khaws cia hauv khw (xws li Deye, Growatt, thiab Victron cov kev daws teeb meem) ua rau 16S teeb tsa.
Xaiv 16S muab ntau yam sib xwsBMSxaiv thiab firmware hloov tshiab. Txawm hais tias rau lub hnub ci cia hauv tsev lossis siab - kev ua tau zoo ntawm lub tsheb fais fab roj teeb, ua raws li 16S teeb tsa ua kom muaj zog ruaj khov thiab ua haujlwm ntev dua.
Kev piav qhia ntxaws txog qhov Voltage Range ntawm 48V LiFePO4 Roj Teeb Pob
Txawm hais tias peb feem ntau xa mus rau nws li a48V roj teeb pob, nws qhov tseeb voltage fluctuates nyob rau hauv ib tug tej yam ntau yam nyob ntawm seb lub xeev ntawm tus nqi. Lub kaw lus tseem ceeb yog tsim los ntawm 16 LiFePO4 hlwb txuas nrog hauv koob. Txij li thaum txhua lub xov tooj muaj qhov nominal voltage ntawm 3.2V, lub nominal voltage ntawm tag nrho cov pob yog tiag tiag 51.2V.
Voltage Ntau
Hauv kev siv tswv yim, lub roj teeb pob ua haujlwm feem ntau nyob rau hauv peb qhov hluav taws xob ntau:
- Them tag nrho:Thaum txhua lub xov tooj mus txog nws qhov kev them nyiaj txiav tawm ntawm 3.65V, tag nrho qhov hluav taws xob ntawm pob nce mus txog kwv yees li 58.4V.
- Tshem tawm Lower Limit:Txhawm rau tiv thaiv dhau- tso tawm thiab puas rau cov hlwb, qhov txiav tawm hluav taws xob ntawm ib tus neeg lub hlwb feem ntau yog teeb tsa ntawm 2.5V thiab 2.8V. Qhov no txhais tau hais tias thaum lub pob hluav taws xob poob mus rau ib puag ncig 40V txog 44.8V, lub zog hluav taws xob yuav tsum tau nres.
- Kev ua haujlwm zoo Plateau:Qhov no yog ib qho tseem ceeb tshaj plaws zoo ntawmLiFePO4 roj teeb. Rau feem ntau ntawm lub sijhawm, thaum lublub xeev tus nqi yog nruab nrab ntawm 20% thiab 90%, qhov voltage tseem nyob ruaj khov ntawm 51.2V thiab 53.6V. Qhov kev hloov hluav taws xob tsawg tsawg no muab lub zog ruaj khov ib puag ncig rau cov khoom siv sib txuas.
Cov ntsiab lus

Yuav Ua Li Cas Xaiv Txoj Cai BMS rau 48V LiFePO4 Roj Teeb System?
Thaum configure BMS rau a48V LiFePO4 roj teeb pob, koj yog qhov tseem ceeb tsim kom muaj kev saib xyuas kev nyab xeeb thiab kev tswj hwm. Kev ua haujlwm ntawm BMS ncaj qha cuam tshuam rau lub roj teeb poblub neej voj voogthiab cov kev txwv kev nyab xeeb ntawm kev ua haujlwm ntawm tag nrho cov system.
1. Core Parameters
Series suav (S):Tus qauv rau 48V LiFePO4 system yog 16 hlwb hauv series. Xyuas kom tseeb tias BMS txhawb nqa 16S (qee qhov qauv thoob ntiaj teb tuaj yeem txhawb nqa kev hloov pauv xws li 8-24S).
Rated tam sim no (A):
- Continuous Discharge Current:Yuav tsum tshaj qhov siab tshaj plaws load tam sim no. Piv txwv li, yog siv 5000W inverter:
Nrog rau txoj kab kev nyab xeeb, koj yuav tsum xaiv a150A lossis 200ABMS. - Nruam Charge Tam Sim No:Xyuas kom nws muaj peev xwm tswj tau qhov siab tshaj plaws ntawm koj lub charger lossis lub hnub ci tswj.
2. Txoj kev sib npaug
- Passive Balancing:Pheej yig thiab ntau. Nws dissipates lub zog tshaj li cua sov. Qhov nyiaj tshuav tam sim no tsawg heev (kwv yees . 50–100mA). Qhov zoo tshaj plaws rau cov cell tshiab, zoo- sib phim.
- Active Balancing:Hloov lub zog los ntawm siab-voltage cells mus rau qis-voltage cells. Rau DIY pob khoom lossis lub peev xwm loj (tshaj 200Ah), nws pom zoo kom xaiv BMS nrog0.6A - 2A Active Ntsuaskom cov hlwb noj qab nyob zoo nyob rau lub sijhawm.
3. Ntse nta & Kev sib txuas lus
- Txheem BMS:Muab kev tiv thaiv nkaus xwb; tsis muaj ntaub ntawv qhia. Zoo rau kev tsim nyiaj txiag.
- Ntse BMS: * Bluetooth/App:Tso cai rau koj saib xyuas tus kheej ntawm tes voltages, kub, thiabSOCntawm koj lub xov tooj.
- Kev Sib Txuas Lus (CAN/RS485):Yog tias siv lub npe -brand inverter, xaiv BMS uas txhawb nqakaw -loop kev sib txuas lus. Qhov no tso cai rau lub roj teeb "sib tham" rau lub inverter rau optimized them.
4. Kev tiv thaiv tseem ceeb muaj nuj nqi
- Tsawg-Kev Tiv Thaiv Kub:LiFePO4 roj teebua tsis tauthem qis dua 0 degree. Yog tias koj lub roj teeb nyob hauv qhov chaw txias, xyuas kom BMS muaj qhov ntsuas kub thiab ntsuas qhov ntsuas kub tsawg -temp charge cutoff.
- Ua ntej- them Circuit Court:Thaum txuas rau cov inverter loj, qhov pib lub txim tuaj yeem ua rau BMS lossis inverter puas. High-kawg BMS units suav nrog pre-them resistor los tswj qhov no kom nyab xeeb.
Cov lus qhia ceev:Xam koj lub tshuab hluav taws xob siab tshaj plaws ua ntej xaiv qhov tam sim no (Amps), tom qab ntawd txiav txim siab yog tias koj xav tau App (Smart BMS) rau kev daws teeb meem yooj yim.
Kev ceev faj txog kev nyab xeeb thiab cov cuab yeej kuaj xyuas rau kev sib sau 48V LiFePO4 Roj Teeb Pob
Sib sau ua ke 48V LiFePO4 roj teeb pob yuav tsum tau ua raws li cov txheej txheem kev nyab xeeb. Thaum LiFePO4 chemistry yog qhov ruaj khov, lub zog khaws cia hauv 16-cell series teeb tsa xav tau ceev faj tuav.
Kev Nyab Xeeb Kev Nyab Xeeb Thaum Lub Rooj Sib Tham
Lub zog muaj peev xwm hauv 16-cell series teeb yog qhov tseem ceeb. Yog hais tias ib qho kev sib tsoo luv luv tshwm sim ntawm qhov zoo thiab qhov tsis zoo, qhov tam sim no tawm tam sim no yuav ua kom muaj cua sov heev. Qhov kev nce siab no muaj zog txaus los yaj cov hlau busbars lossis cov cuab yeej tam sim ntawd thiab tuaj yeem ua rau muaj hluav taws kub hnyav.
Core Safety Guidelines
- Insulate koj cov cuab yeej:Xyuas kom meej tias tag nrho cov cuab yeej hlau, xws li wrenches thiab screwdrivers, muaj insulated handles ua ntej pib ua hauj lwm.
- Hnav tiv thaiv iav:Siv looj tsom iav dub thiab cov hnab looj tes insulated los tiv thaiv hluav taws xob arcing lossis sparks.
- Tshem cov khoom hlau:Tsis txhob hnav watches, rings, lossis necklaces thaum lub sij hawm sib dhos los tiv thaiv kev sib cuag nrog cov roj teeb terminals.
- Ua raws li cov txheej txheem installation:Txuas cov hlwb nruj me ntsis raws li daim duab kos. Ntsuas qhov hluav taws xob tom qab txhua qhov kev sib txuas thiab ob npaug - xyuas cov polarities ua ntej zawm cov terminals.
