LiFePO4 BMS: Momwe Mungasankhire Njira Yoyenera Yoyendetsera Batri Pa Phukusi Lanu
Kusankha BMS yolakwika ndi chimodzi mwa zifukwa zomwe zimachititsa kuti mabatire a LiFePO4 alephere msanga — ndipo ndi chimodzi mwa mavuto osavuta kupewa. Bukuli likuwonetsani zomwe LiFePO4 BMS imachita, zomwe ndizofunikira pa pulogalamu yanu, komanso momwe mungapewere zolakwika zomwe zimatitumizira matikiti ambiri othandizira.
Zokhudza LiFePO4 BMS
LiFePO4 BMS (Battery Management System) ndi ubongo wamagetsi womwe umagwirizanitsa ma cell a batri yanu ndi makina ena onse. Umachita zinthu zitatu:
- Imayang'anira selo iliyonse payekhapayekha — kutsatira mphamvu yamagetsi, kutentha, ndi momwe mphamvu imagwirira ntchito nthawi yeniyeni.
- Zimateteza paketi — zimadula mphamvu kapena kutulutsa mphamvu nthawi yomweyo selo ikatuluka pawindo lake lotetezeka.
- Kulinganiza maselo — kulinganiza mulingo wa mphamvu m'maselo onse omwe ali mu paketi kuti selo lofooka kwambiri lisakokere dongosolo lonse.
Popanda BMS, maselo amodzi amapatukana pakapita nthawi. Selo lomwe limachaja mwachangu kwambiri limayamba lafika pamlingo wake wokwera kwambiri ndikutseka mphamvu yonse yogwiritsidwa ntchito. Limene limachaja mwachangu kwambiri lidzatsika pansi pa malire ake otetezeka ndikukalamba mwachangu. BMS yodziwika bwino imaletsa zonse ziwiri.

Ntchito Zoteteza Zachikulu — Zimene Chilichonse Chimachita
LiFePO4 BMS iliyonse yodalirika imaphimba zigawo zisanu ndi chimodzi zotetezera izi monga muyezo. Ngati BMS yomwe mukuyiyesa ikusowa chilichonse mwa izo, pitirizani.
| Chitetezo | Chimene Chimayambitsa | Chifukwa Chake Ndi Chofunika |
| Chitetezo cha Mphamvu Yopitirira Muyeso (OVP) | Mphamvu yamagetsi ya selo imakwera pamwamba pa ~3.65 V panthawi yochaja | Amaletsa kudzaza kwambiri, kuwonongeka kwa ma electrolyte, komanso kuchepa kwa mphamvu |
| Chitetezo Chosagwira Ntchito (UVP) | Mphamvu yamagetsi ya selo imatsika pansi pa ~2.50 V panthawi yotulutsa | Zimaletsa kutuluka kwa madzi akuya komwe kumayambitsa kuwonongeka kosatha kwa maselo |
| Chitetezo cha Overcurrent (OCP) | Mphamvu yotulutsa mphamvu yapitirira malire ovoteledwa | Amateteza ma FET, mabasi, ndi ma cell tabu ku kuwonongeka kwa kutentha |
| Chitetezo cha Dera Lalifupi (SCP) | Kukwera kwadzidzidzi kwa mphamvu yamagetsi kwapezeka (mayankho a microsecond) | Zimatseka paketiyo vuto lalikulu lisanayambe moto kapena kutuluka mpweya |
| Chitetezo Chotentha Kwambiri (OTP) | Kutentha kwa selo kapena MOSFET kumapitirira malire | Imaletsa kuyatsa kapena kutulutsa madzi kutentha kusanayambe kuwonongeka mwachangu |
| Kulinganiza Maselo | Kufalikira kwa voliyumu kwapezeka pakati pa maselo | Imalinganiza momwe zinthu zilili kuti phukusi lonse ligwiritsidwe ntchito |
Dziwani: Miyezo yeniyeni yoyambira (monga 3.65 V ya OVP) imakonzedwa panthawi yowunikira BMS ndipo imasiyana pakati pa mitundu. Nthawi zonse yang'anani deta ya SKU yomwe mukuyitanitsa.
Mtundu wa Zamalonda wa Daly BMS LiFePO4 — Chidule cha Zaukadaulo
Banja la Daly BMS LiFePO4 limaphatikizapo mitundu yosiyanasiyana ya makonzedwe kuyambira ma pack ang'onoang'ono a 12V DIY mpaka makina osungiramo zinthu zamafakitale a 48V+ ndi mphamvu. Magawo ofunikira malinga ndi gulu la zitsanzo:
| Chizindikiro | Zosankha / Zosankha | Zolemba |

Momwe Mungasankhire LiFePO4 BMS Yoyenera — Njira Ya Masitepe 5
Yesetsani kudutsa masitepe asanu awa motsatira ndondomeko. Kudumpha chilichonse mwa izi ndi momwe kusagwirizana kumachitikira.
Gawo 1 — Werengani Maselo Anu Motsatizana (Kuwerengera S)
Chiwerengero cha S chimasankha mtundu wa BMS. Selo iliyonse ya LiFePO4 ili ndi voteji yodziwika ya 3.2 V. Onjezani:
- 4S = 12.8 V dzina lodziwika bwino → dongosolo lokhazikika la 12V
- 8S = 25.6 V dzina lodziwika bwino → dongosolo lokhazikika la 24V
- 16S = 51.2 V dzina lodziwika bwino → dongosolo lokhazikika la 48V
- 24S = 76.8 V dzina lodziwika bwino → dongosolo la 72V lokhazikika
BMS yoyesedwa kuti ndi yolondola pa chiwerengero cha S idzalephera kuwerenga ma voltage a maselo molondola kapena kugwiritsa ntchito malire olakwika a chitetezo. Palibe njira yothetsera vutoli - chiwerengero cha S chiyenera kufanana ndendende.
Gawo 2 — Dziwani Zomwe Mukufuna Posalekeza
Onjezani nameplate current ya katundu yense yomwe ingagwire ntchito nthawi imodzi. Ikani malire a 10–20% pamwamba kuti muwonjezere mphamvu. Sankhani BMS current rating yotsatira yomwe ilipo pamwamba pa chiwerengerocho. Mwachitsanzo: inverter ya 2,000W pa makina a 24V imakoka pafupifupi 83A ikadzaza mokwanira - 100A BMS ndiye chisankho choyenera.
Musamale kukula kwa katundu wamba. BMS iyenera kuthana ndi katundu woipa kwambiri nthawi imodzi popanda kupunthwa.
Gawo 3 — Sankhani Pakati pa Kulinganiza Mosachitapo Kanthu ndi Mogwira Mtima
Kulinganiza kosachitapo kanthu kumawotcha mphamvu yochulukirapo m'maselo okhala ndi ma SOC ambiri kudzera mu resistor. Imagwira ntchito, koma imagwira ntchito pang'onopang'ono ndipo imapanga kutentha. Kulinganiza kogwira ntchito kumasamutsa mphamvu kuchokera ku maselo okhala ndi ma SOC ambiri kupita ku maselo okhala ndi ma SOC ochepa pogwiritsa ntchito ma inductor kapena ma capacitor — mwachangu, osawononga mphamvu zambiri, komanso bwino pamapaketi akuluakulu.
Ngati paketi yanu ili pamwamba pa 100Ah, nthawi zambiri imayendetsedwa pang'ono (kugwiritsa ntchito mphamvu ya dzuwa), kapena ili pamalo otsekedwa komwe kutentha kumakhala kovuta, kulinganiza bwino ndiko ndalama zabwino kwambiri.
Gawo 4 — Yang'anani Kulumikizana Komwe Dongosolo Lanu Likufuna
Ngati inverter yanu, chowongolera champhamvu cha dzuwa, kapena nsanja yowunikira ikufunika deta ya batri yeniyeni — momwe chaji ilili, ma voltage a ma cell, kutentha, zizindikiro za alamu — mukufuna BMS yokhala ndi mawonekedwe ofanana. RS485 ndiye muyezo wa makina ambiri a inverter a 48V. Bluetooth imaphimba kuwunika kwa DIY ndi mafoni. Ma inverter ena amafunikira CAN bus kapena protocol yapadera. Tsimikizirani kuti ikugwirizana musanayitanitse.
Gawo 5 — Tsimikizirani Kuyesa Kwachilengedwe
BMS yoyikidwa m'nyumba m'malo ouma siifunikira chipinda chapadera. BMS yomwe ili m'boti, m'kabati lakunja, kapena m'malo oikira injini imafunika chophimba chocheperako, ndipo makamaka chipinda chokhala ndi IP67. Kulowa kwa chinyezi ndiye chifukwa chofala kwambiri cha kulephera kwa BMS m'malo oyikamo zinthu zakunja ndi za m'madzi.
