Kev xaiv BMS rau lub kaw lus cia hluav taws xob LiFePO4 tsis yooj yim li kev sib phim lub zog inverter nrog 100A, 150A, lossis 200A BMS.
Qhov BMS tam sim no kom raug yog nyob ntawm qhov tam sim no ntawm lub roj teeb uas lub inverter xav tau tiag tiag - tsis yog lub zog ntawm lub inverter xwb. Ib qho txheej txheem xaiv ua tau yog:
Cov Lus Teb Sai: Tsis Txhob Xaiv BMS Tam Sim No Los Ntawm Inverter Watts Ib Leeg
Pib nrog daim ntawv qhia txog cov ntaub ntawv inverter tseeb. Xyuas tsib yam no:
- Lub zog ua haujlwm tas mus li (W)
- Roj teeb/DC ua haujlwm voltage ntau yam (V)
- Qhov siab tshaj plaws ntawm lub roj teeb tawm tam sim no (A)
- Lub roj teeb them tam sim no siab tshaj plaws (A)
- Lub zog siab tshaj plaws / nce siab thiab lub sijhawm ntev
Lub roj teeb tam sim no ≈ AC load fais fab ÷ (Lub roj teeb voltage × Inverter efficiency)
Piv txwv li, 5,000W ÷ 51.2V ≈ 97.7A. Tab sis 97.7A yog kev xam tam sim no zoo tagnrho - tsis yog pov thawj tias 100A BMS tsim nyog.
5 Cov Kauj Ruam Los Txheeb Xyuas BMS Tam Sim No
1Tshawb xyuas daim ntawv qhia txog Inverter ua ntej
Qhib daim ntawv qhia txog tus qauv inverter thiab nrhiav cov nqi hauv qab no.
| Cov Qauv | Koj Xav Tau Dab Tsi |
|---|---|
| Lub zog ua haujlwm tas mus li | Kev ntsuas W tas mus li |
| Lub roj teeb/DC voltage | Qhov ntau thiab tsawg ntawm kev ua haujlwm |
| Qhov siab tshaj plaws ntawm lub roj teeb tawm tam sim no | A, yog tias tau teev tseg |
| Qhov siab tshaj plaws ntawm lub roj teeb them tam sim no | A |
| Lub zog siab tshaj plaws / nce siab | W lossis qhov ntsuas ntawm chaw tsim khoom siv tau |
| Lub sijhawm ntawm kev nce siab | Vib nas this/feeb, raws li tau teev tseg |
Yog tias qhov siab tshaj plaws ntawm lub roj teeb uas tso tawm tam sim no twb tau teev tseg rau qhov xwm txheej ua haujlwm, siv tus nqi ntawd ua qhov kev tsim qauv tseem ceeb. Txwv tsis pub, txuas ntxiv nrog kev kwv yees tam sim no ntawm sab roj teeb.
2Kwv yees qhov tam sim no ntawm sab roj teeb
Thaum cov ntaub ntawv tam sim no ntawm lub roj teeb tsis muaj, pib nrogP = V × KuvYog li ntawd:
Rau lub roj teeb LiFePO4 16S nrog lub zog nominal ntawm 51.2V muab 5,000W load:
5,000 ÷ 51.2 ≈ 97.7A
Yog xav tau qhov kwv yees tseeb dua, suav nrog qhov ua tau zoo ntawm lub inverter:
Yog tias 95% kev ua haujlwm tsuas yog siv ua piv txwv xwb:5,000 ÷ (51.2 × 0.95) ≈ 102.8ATsis txhob xav tias 95% rau txhua lub inverter; siv cov ntaub ntawv ntawm lub chaw tsim khoom thaum twg muaj.
3Siv Lub Hwj Chim Ua Haujlwm ntawm Lub Roj Teeb
Nyob rau tib lub zog,qhov hluav taws xob qis dua ntawm lub roj teeb txhais tau tias lub roj teeb tam sim no siab dua.
| Piv txwv txog lub zog ntawm lub roj teeb | Tam sim no ntawm 5,000W |
|---|---|
| 54V | 92.6A |
| 51.2V | 97.7A |
| 48V | 104.2A |
Cov voltages no tsuas yog piv txwv xwb. Rau qhov tsim qauv tiag tiag, siv qhov voltage ua haujlwm cuam tshuam los ntawm lub roj teeb thiab cov lus qhia ntawm inverter. Tsis txhob ntsuas qhov tam sim no xav tau los ntawm qhov voltage nominal xwb.
4Tshawb xyuas Tam Sim No Txuas Ntxiv thiab Tam Sim No Nce Siab Sib Cais
Ib qho BMS yuav tsum raug soj ntsuam raws li qhov yuav tsum tau ua haujlwm tas mus li thiab txhua qhov kev thov luv luv.
Tam sim no tas mus li
Xyuas kom tseeb tias lub roj teeb tam sim no xav tau thaum lub inverter muab cov khoom thauj uas xav tau. Tag nrho cov txoj kev tam sim no—cells, busbars, BMS, cables, connectors, protection devices thiab inverter—yuav tsum txhawb nqa qhov yuav tsum tau ua no.
Tam sim no nce siab
Cov cav, cov compressors, cov twj tso kua mis thiab cov khoom zoo sib xws yuav tsim kom muaj kev thov pib luv luv.
Lub zog tam sim no siab tshaj plaws uas tsis muaj lub sijhawm ntev yog ib qho kev qhia tsis tiav.
Piv txwv lub zog hluav taws xob ntawm lub inverter + lub sijhawm → qhov xav tau ntawm lub roj teeb tam sim no + lub sijhawm → BMS tau sau tseg lub peev xwm luv luv thiab tus cwj pwm tiv thaiv → lub peev xwm ntawm lub cell thiab txoj kev tam sim no.
5Tshawb xyuas qhov tam sim no ntawm tus nqi cais
Tam sim no them thiab tam sim no tso tawm yog cov kev cai sib cais. Txheeb xyuas qhov siab tshaj plaws tam sim no uas lub inverter / charger lossis lub kaw lus them tuaj yeem xa mus rau lub roj teeb, tom qab ntawd piv rau lub peev xwm them lub xov tooj ntawm tes, tsim pob, BMS lub peev xwm them tam sim no thiab cov xwm txheej ua haujlwm siv tau.
Yuav tsum tau muaj tam sim no tas mus li: ___ A
Qhov siab tshaj plaws tam sim no: ___ A
Piv txwv ua haujlwm: 16S 51.2V LiFePO4 roj teeb + 5kW Inverter
| Mob | Kev suav lej | Tam sim no ntawm lub roj teeb |
|---|---|---|
| Zoo tagnrho, tsis muaj kev poob, 51.2V | 5,000 ÷ 51.2 | 97.7A |
| 95% kev ua haujlwm zoo, 51.2V | 5,000 ÷ (51.2 × 0.95) | 102.8A |
| 95% kev ua haujlwm zoo, 48V | 5,000 ÷ (48 × 0.95) | 109.6A |
Qhov kev xam thawj zaug 97.7A tsis tuaj yeem pom zoo rau 100A BMS. Kev xaiv zaum kawg tseem nyob ntawm qhov tseeb ntawm cov lus qhia ntawm inverter, qhov yuav tsum tau muaj surge, charge current, cells, BMS rating conditions thiab qhov chaw ua haujlwm.
Yuav Ua Li Cas Soj Ntsuam Xyuas 100A, 150A, lossis 200A BMS
| Chav Kawm Tam Sim No | Kev Ntsuam Xyuas Thawj Zaug |
|---|---|
| 100A BMS | Tsis tuaj yeem pom zoo los ntawm kev xam tus nqi hluav taws xob xwb. Kev poob thiab qhov hluav taws xob ua haujlwm qis dua yuav thawb tam sim no siab dua 100A. |
| 150A BMS | Tej zaum yuav tseem yog ib qho kev sib tw, tab sis qhov tseeb tam sim no txuas ntxiv, tam sim no surge, tam sim no them, BMS specifications, cells thiab pob tsim yuav tsum tau txheeb xyuas tseem. |
| 200A BMS | Muab peev xwm tam sim no siab dua tsuas yog tias tag nrho lub kaw lus txhawb nqa nws. Qhov ntsuas tam sim no loj dua ib leeg tsis ua rau nws yog qhov kev xaiv zoo. |
