Iibhetri zeLithium zisetyenziswa kakhulu kwizixhobo ezifana neefowuni eziphathwayo, izithuthi zombane, kunye neenkqubo zamandla elanga. Nangona kunjalo, ukuzitshaja gwenxa kunokukhokelela kwiingozi zokhuseleko okanye kumonakalo ongunaphakade.
WUkusebenzisa itshaja ye-voltage ephezulu kuyingozi kwayeIndlela iNkqubo yoLawulo lweBhetri (i-BMS) ekhusela ngayo iibhetri ze-lithium?
Ingozi Yokutshaja Ngokugqithisileyo
Iibhetri zeLithium zinemida engqongqo yevolthi. Umzekelo:
.AI-LiFePO4Iseli (iLithium Iron Phosphate) inevolthi eqhelekileyo ye3.2Vkwaye kufunekaungaze udlule kwi-3.65Vxa itshajwe ngokupheleleyo
.AI-Li-ionIseli (iLithium Cobalt), exhaphakileyo kwiifowuni, isebenza kwi3.7Vkwaye kufuneka uhlale ungaphantsi4.2V
Ukusebenzisa itshaja enevolthi ephezulu kunomlinganiselo webhetri kunyanzela amandla agqithisileyo kwiiseli. Oku kunokubangelaubushushu obugqithisileyo,ukudumba, okanyeukubaleka kobushushu—isenzo esiyingozi apho ibhetri ibamba umlilo okanye iqhuma
Indlela i-BMS Eyisindisa Ngayo Usuku
Inkqubo yoLawulo lweBhetri (i-BMS) isebenza "njengomlindi" weebhetri ze-lithium. Nantsi indlela esebenza ngayo:
1.Ulawulo lweVolthi
I-BMS ijonga i-voltage yeseli nganye. Ukuba itshaja ye-voltage ephezulu iqhagamshelwe, i-BMS ibona i-overvoltage kwayeinqumla isekethe yokutshajaukuthintela umonakalo
2.Ulawulo lobushushu
Ukutshaja ngokukhawuleza okanye ukutshaja kakhulu kuvelisa ubushushu. I-BMS ilandelela ubushushu kwaye inciphisa isantya sokutshaja okanye iyeke ukutshaja ukuba ibhetri iba shushu kakhulu113.
3.Ukulinganisela iiSeli
Kwiibhetri zeeseli ezininzi (ezifana neepakethi ze-12V okanye ze-24V), ezinye iiseli zitshaja ngokukhawuleza kunezinye. I-BMS isasaza amandla kwakhona ukuqinisekisa ukuba zonke iiseli zifikelela kwi-voltage efanayo, ithintela ukutshaja okugqithisileyo kwiiseli ezinamandla.
4.Ukuvalwa koKhuseleko
Ukuba i-BMS ibona imiba ebalulekileyo efana nokushisa kakhulu okanye ukunyuka kwamandla e-voltage, iyayiqhawula ibhetri ngokupheleleyo isebenzisa izinto ezifanaIiMOSFET(iiswitshi ze-elektroniki) okanyeizixhobo zoqhagamshelwano(ii-relay zoomatshini)
Indlela Echanekileyo Yokutshaja Iibhetri ZeLithium
Soloko usebenzisa itshajaukufanisa i-voltage kunye nekhemistri yebhetri yakho.
Umzekelo:
Ibhetri ye-12V LiFePO4 (iiseli ezi-4 ezilandelelanayo) ifuna itshaja eneIsiphumo esiphezulu se-14.6V(4 × 3.65V)
Iphakheji ye-7.4V Li-ion (iiseli ezi-2) ifunaItshaja ye-8.4V
Nokuba i-BMS ikhona, ukusebenzisa itshaja engahambelaniyo kuyayicinezela inkqubo. Nangona i-BMS inokungenelela, ukuvezwa ngokuphindaphindiweyo kwe-overvoltage kunokwenza buthathaka izinto zayo ngokuhamba kwexesha.
Isiphelo
Iibhetri zeLithium zinamandla kodwa zibuthathaka.i-BMS ekumgangatho ophezuluKubalulekile ukuqinisekisa ukhuseleko, ukusebenza kakuhle, kunye nobude bexesha. Nangona inokukhusela okwethutyana kwitshaja ye-voltage ephezulu, ukuthembela koku kuyingozi. Soloko usebenzisa itshaja efanelekileyo—ibhetri yakho (kunye nokhuseleko) iya kukubulela!
Khumbula: I-BMS ifana nebhanti yesihlalo. Ikho ukuze ikusindise kwiimeko ezingxamisekileyo, kodwa akufuneki uyivavanye imida yayo!
