Amabhethri e-lithium asetshenziswa kakhulu kumadivayisi afana nama-smartphones, izimoto zikagesi, nezinhlelo zamandla elanga. Kodwa-ke, ukuwakhokhisa ngokungalungile kungaholela ezingozini zokuphepha noma ukulimala unomphela.
Why ukusebenzisa ishaja enamandla kagesi aphezulu kuyingozi futhiukuthi i-Battery Management System (BMS) iwavikela kanjani amabhethri e-lithium?
Ingozi Yokukhokhisa Kakhulu
Amabhethri e-lithium anemikhawulo eqinile kagesi. Ngokwesibonelo:
.AI-LiFePO4(I-Lithium Iron Phosphate) iseli inevoltheji yegama elithi3.2Vfuthi kufaneleungalokothi udlule i-3.65Vuma ishajwe ngokugcwele
.AI-Li-ion(I-Lithium Cobalt) iseli, evamile emafonini, isebenza ku-3.7Vfuthi kufanele uhlale ngaphansi4.2V
Ukusebenzisa ishaja enamandla kagesi aphezulu kunomkhawulo webhethri kuphoqa amandla engeziwe kumaseli. Lokhu kungabangelaukushisa ngokweqile,ukuvuvukala, noma ngishoukubaleka okushisayo-isenzo esiyingozi lapho ibhethri livutha khona noma liqhuma
I-BMS Ilugcina Kanjani Usuku
I-Battery Management System (BMS) isebenza "njengomnakekeli" wamabhethri e-lithium. Nansi indlela esebenza ngayo:
1.Ukulawula Amandla Kagesi
I-BMS iqapha amandla kagesi weseli ngalinye. Uma ishaja ene-voltage ephezulu ixhunyiwe, i-BMS ithola ukugcwala kwamandla futhiinqamula isekethe yokushajaukuvimbela umonakalo
2.Ukulawulwa kwezinga lokushisa
Ukushaja okusheshayo noma ukushaja ngokweqile kudala ukushisa. I-BMS ilandelela izinga lokushisa futhi yehlise isivinini sokushaja noma iyeke ukushaja uma ibhethri lishisa kakhulu113.
3.Ukulinganisa Kweseli
Kumabhethri anamaseli amaningi (njengamaphakethe angu-12V noma angu-24V), amanye amaseli ashaja ngokushesha kunamanye. I-BMS isabalalisa kabusha amandla ukuze iqinisekise ukuthi wonke amaseli afinyelela ku-voltage efanayo, ukuvimbela ukushajwa ngokweqile kumaseli anamandla
4.Ukuvalwa kokuphepha
Uma i-BMS ithola izinkinga ezibucayi njengokushisisa ngokweqile noma ama-voltage spikes, inqamula ibhethri ngokuphelele isebenzisa izingxenye ezifanaAma-MOSFET(amaswishi kagesi) nomaabathintwayo(amalayidi emishini)
Indlela Elungile Yokushaja Amabhethri Lithium
Njalo sebenzisa ishajaukufanisa umthamo webhethri lakho kanye nekhemistri.
Ngokwesibonelo:
Ibhethri engu-12V LiFePO4 (amaseli angu-4 ochungechungeni) idinga ishaja ene-14.6V esiphezulu okukhiphayo(4 × 3.65V)
Iphakethe le-Li-ion elingu-7.4V (amaseli angu-2) lidinga iIshaja engu-8.4V
Noma ngabe i-BMS ikhona, ukusebenzisa ishaja engahambelani kucindezela uhlelo. Nakuba i-BMS ingangenelela, ukuchayeka ngokuphindaphindiwe kwe-overvoltage kungase kunciphise izingxenye zayo ngokuhamba kwesikhathi
Isiphetho
Amabhethri e-lithium anamandla kodwa athambile. Aizinga eliphezulu le-BMSkubalulekile ukuqinisekisa ukuphepha, ukusebenza kahle, nokuphila isikhathi eside. Nakuba ingavikela okwesikhashana ishaja enamandla kagesi aphezulu, ukuthembela kulokhu kuyingozi. Hlala usebenzisa ishaja efanele—ibhethri lakho (nokuphepha) kuzokubonga!
Khumbula: I-BMS ifana nebhande lesihlalo. Ikhona ukuze ikusindise ezimeni eziphuthumayo, kodwa akufanele uhlole imikhawulo yayo!
