Kufotokozedwa kwa LiFePO4 BMS: Momwe Mungasankhire Yoyenera (2026)

Batire ya LiFePO4 yopanda BMS ndi vuto losadziletsa.
Chochitika chimodzi chowonjezera mphamvu chingawononge maselo kwamuyaya. BMS yolakwika
zimayambitsa miyezi yambiri ya kutha kwa zinthu zopanda pake komanso kutayika kwa mphamvu. Bukuli limafotokoza za
imaphimba zonse zomwe mukufunikira kuti mupange chisankho choyenera.

BMS imagwira ntchito zitatu nthawi imodzi:

Chitetezoimadula dera lamagetsi nthawi yomweyo selo lililonse likadutsa zenera lake lotetezeka — mphamvu yoposa 3.65 V/selo, kutulutsa mphamvu pansi pa 2.8 V/selo (mlingo woyenera wogwirira ntchito), kapena pamene mphamvu yamagetsi, kutentha, kapena kufupika kwa magetsi kumakhala koopsa.

Kulinganizaimakonza kuyenda kwachilengedwe pakati pa maselo pawokha pa nthawi mazana ambiri. Popanda izi, selo lanu lofooka kwambiri limafotokoza mphamvu yonse yogwiritsidwa ntchito ya paketi yanu - ndipo imawonongeka mwachangu kwambiri.

Kuwunikaamatsata momwe zinthu zilili (SOC), momwe zinthu zilili pa thanzi (SOH), mphamvu yamagetsi pa selo, kutentha, ndi kuchuluka kwa kayendedwe ka nthawi yeniyeni. Deta iyi imakulolani kuti mugwire selo lomwe lalephera lisanagwetse paketi.

Kapangidwe ka LiFePO4 kosalala kamene kamatuluka kamafuna BMS yofanana ndi ya chemistry. BMS yodziwika bwino idzawerenga molakwika SOC kudutsa phiri lonselo ndikuyambitsa kudulidwa kwa mphamvu yamagetsi yotsika pang'ono ndi mphamvu yotsala.

Momwe Mungakulitsire BMS Yanu

Zinthu ziwiri ziyenera kufanana ndi paketi yanu.

Gawo 1 — Voltage (kuchuluka kwa maselo).Phukusi la 4S limafuna 4S BMS. Phukusi la 16S limafuna 16S BMS. Kutsekedwa kwa selo limodzi kumayambitsa kusawerenga bwino magetsi komanso chitetezo chosadalirika.

Gawo 2 - Zamakono.Gawani katundu wanu wopitilira muyeso mu ma watts ndi mphamvu ya pakiti, kenako onjezerani 25–30% ya chitetezo.

5,000 W ÷ 48 V = 104 A → Sankhani 150 A BMS

Musagwiritse ntchito BMS pa 100% ya mphamvu yake yovomerezeka. Kuchepa kwa kutentha ndi kuchuluka kwa mphamvu zomwe zimayikidwa nthawi zonse kumakweza kufunikira kwa zinthu zenizeni kuposa chiwerengero chowerengedwa.

Kulinganiza Kogwira Ntchito ndi Kusachitapo Kanthu

Kulinganiza zinthu mopanda kusinthasinthaImataya mphamvu yochulukirapo ngati kutentha kudzera mu resistor (50–200 mA). Imasunga mapaketi ofanana bwino koma singathe kubwezeretsa kusuntha kwakukulu kwa maselo — kukonza kusalingana kwa 500 mAh kumatenga pafupifupi maola 5 pa 100 mA.

Kulinganiza bwinoImasamutsa mphamvu pakati pa maselo kudzera mu inductor-capacitor circuit (1–5 A, 80–95%). Imakonza kusalinganika mwachangu 10–50× ndipo imagwira ntchito nthawi yonse ya chaji ndi kutulutsa mphamvu, osati pamwamba pokha.

Sankhani osachitapo kanthukwa maselo ofanana omwe amayendetsedwa pa ≤ 0.3C.
Sankhani yogwira ntchitopa ma paketi ≥ 200 Ah, kuchuluka kwa kutulutsa madzi kopitilira 0.5C, kapena maselo ochokera m'magulu osakanikirana.

Mndandanda Wosankha Zinthu Zinayi Zosiyanasiyana

Musanayitanitse, tsimikizirani zosintha zonse zinayi nthawi imodzi:

Mayunitsi a DALY Energy BMS amaphimba 4S mpaka 24S ndi 10 A mpaka 500 A, mu standard, smart (Bluetooth + RS485/CAN), ndi active balance configurations — zonse zimatumizidwa ndi LFP chemistry thresholds mwachisawawa.
