Amabhethri e-Lithium asetshenziswa kabanzi kumadivayisi afana nama-Smartphones, izimoto zikagesi, nezinhlelo zamandla elanga. Kodwa-ke, ukubashaja ngokungalungile kungaholela ezingozini zokuphepha noma kumonakalo waphakade.
Why kusetshenziswa ishaja ye-voltage yemvelo kuyingozi futhiIvikela kanjani uhlelo lokuphathwa kwebhethri (BMS) Ivikela amabhethri e-Lithium?
Ingozi yokuthola ngokweqile
Amabhethri e-Lithium anemikhawulo eqinile yegesi. Ngokwesibonelo:
.AI-LifePo4(I-Lithium Iron Phosphate) Iseli linamandla kagesi athile weI-3.2Vfuthi kufaneleUngalokothi udlule u-3.65VLapho ukhokhiswa ngokuphelele
.ALi-ion(I-Lithium Cobalt) Iseli, elivamile kumafoni, lisebenzaI-3.7Vfuthi kumele uhlale ngezansiI-4.2V
Kusetshenziswa ishaja nge-voltage ephakeme kunomkhawulo webhethri amandla amakhulu emaseli. Lokhu kungadalaUkushisa ngokweqile,ukuvuvukala, noma ngishoI-Thermal Runaway-Indlela eyingozi yokusabela kwe-chain lapho ibhethri libamba umlilo noma liqhume
I-BMS isindisa kanjani usuku
Uhlelo lokuphathwa kwebhethri (i-BMS) lusebenza njenge- "Guardian" yamabhethri e-lithium. Nakhu ukuthi kusebenza kanjani:
1.Ukulawulwa kwamandla kagesi
Ama-bms aqapha amagesi ngakunye. Uma ishaja ye-voltage ephakeme ixhunyiwe, i-BMS ithola ukuvela ngokweqile futhiusika umjikelezo wokushajaUkuvimbela ukulimala
2.Umthetho wokushisa
Ukushaja okusheshayo noma ukucindezela ngokweqile kwakha ukushisa. Amathrekhi we-BMS amathrekhi futhi anciphise isivinini sokushaja noma ukuyeka ukushaja uma ibhethri lishisa kakhulu113.
3.Ukulinganisa kweseli
Kumabhethri e-Multi-Cell (njengamaphakethe we-12V noma ama-24V), amanye amaseli ashaja ngokushesha kunabanye. I-BMS yamukeli amandla okuqinisekisa amandla okuqinisekisa ukuthi wonke amaseli afinyelela kumandla kagesi afanayo, avimbele ukugcwala ngokweqile kumaseli anamandla
4.Ukuvala ukuvalwa
Uma i-BMS ithola izingqinamba ezibucayi njengokuthi ngokweqile noma i-voltage spikes, inqamula ibhethri lisebenzisa ngokuphelele izakhi ezinjengaleAma-mosfes(ukushintshwa kwe-elekthronikhi) nomaabaxhumene nabo(ukudluliselwa kwemishini)
Indlela efanele yokukhokhisa amabhethri e-lithium
Njalo sebenzisa ishajaUkufanisa i-voltage yebhethri lakho ne-chemistry.
Ngokwesibonelo:
Ibhethri le-12V Lifepo4 (amaseli ama-4 ochungechungeni) lidinga ishaja ngeI-14.6V ephezulu yokuphuma(4 × 3.65v)
Iphakethe le-7.4V li-ion (amaseli ama-2) kudinga aIshaja engu-8.4V
Noma ngabe i-BMS ikhona, ukusebenzisa ishaja engenalo kugcizelela uhlelo. Ngenkathi i-BMS ingangenelela, ukuvezwa okuphindaphindwayo kungahle kube lula izingxenye zayo ngokuhamba kwesikhathi
Ukugcina
Amabhethri e-Lithium anamandla kepha abuthakathaka. AI-BMS ephezulu kakhulukubalulekile ukuqinisekisa ukuphepha, ukusebenza kahle, kanye nokuphila isikhathi eside. Ngenkathi ingavikela okwesikhashana kwishaja ephakeme yevota, ukuthembela kulokhu kuyingozi. Njalo sebenzisa ishaja efanele - ibhethri lakho (nokuphepha) kuzokubonga!
Khumbula: I-BMS ifana nesihlalo se-saebelt. Kulapho ukukusindisa ezimweni eziphuthumayo, kepha akufanele uvivinye imikhawulo yalo!
