Iibhetri zeLithium zisetyenziswa ngokubanzi kwizixhobo ezinjengee-smartphones, izithuthi zombane, kunye neenkqubo zamandla elanga. Nangona kunjalo, ukubiza ngokungalunganga kunokukhokelela kwiingozi zokhuseleko okanye umonakalo osisigxina.
Why ukusebenzisa itshaja enevoltage ephezulu kuyingozi kwayeindlela iBattery Management System (BMS) ikhusela ngayo iibhetri ze-lithium?
Ingozi Yokuntywila
Iibhetri zeLithium zinemida yombane engqongqo. Umzekelo:
.ALiFePO4(I-Lithium Iron Phosphate) iseli inombane oqhelekileyo we3.2Vkwaye kufaneleungaze udlule kwi-3.65Vxa ihlawuliswe ngokupheleleyo
.AI-Li-ion(Lithium Cobalt) iseli, eqhelekileyo kwiifowuni, isebenza kuyo3.7Vkwaye kufuneka uhlale ngaphantsi4.2V
Ukusebenzisa itshaja enamandla ombane aphezulu kunomlinganiselo webhetri kunyanzelise amandla agqithisileyo kwiiseli. Oku kunokubangelaukutshisa kakhulu,ukudumba, okanye nkquukubaleka kwe-thermal-Intshukumo eyingozi yekhonkco apho ibhetri ibamba umlilo okanye iqhume
Indlela iBMS elugcina ngayo usuku
Inkqubo yoLawulo lweBattery (BMS) isebenza "njengomgcini" weebhetri ze-lithium. Nantsi indlela esebenza ngayo:
1.Ulawulo lwamandla ombane
I-BMS ibeka iliso kumbane weseli nganye. Ukuba itshaja ephezulu ye-voltage ixhunyiwe, i-BMS ibona ukugqithisa kunyeinqumla isekethe yokutshajaukuthintela umonakalo
2.Ulawulo lobushushu
Ukutshaja ngokukhawuleza okanye ukutshaja kakhulu kudala ubushushu. I-BMS ilandelela ubushushu kwaye inciphisa isantya sokutshaja okanye iyeke ukutshaja ukuba ibhetri ishushu kakhulu113.
3.Ukulinganisa iSeli
Kwiibhetri ezininzi zeeseli (ezifana neepakethe ze-12V okanye i-24V), ezinye iiseli zihlawulisa ngokukhawuleza kunezinye. I-BMS iphinda isasaze amandla ukuqinisekisa ukuba zonke iiseli zifikelela kumbane ofanayo, ukuthintela ukutshaja kakhulu kwiiseli ezomeleleyo
4.Ukuvalwa koKhuseleko
Ukuba i-BMS ibona imiba ebalulekileyo njengokufudumeza okugqithisileyo okanye i-voltage spikes, iyayiqhawula ibhetri ngokupheleleyo isebenzisa izinto ezifanaIi-MOSFETs(izitshixo zombane) okanyeabafowunelwa(ukuhanjiswa koomatshini)
Indlela eLungileyo yokuTshaja iibhetri zeLithium
Sebenzisa itshaja rhoqoukuthelekisa amandla ombane webhetri yakho kunye nekhemistri.
Umzekelo:
Ibhetri ye-12V LiFePO4 (iiseli ezi-4 kuthotho) idinga itshaja ene-Imveliso ephezulu ye-14.6V(4 × 3.65V)
Ipakethe ye-7.4V ye-Li-ion (iiseli ezi-2) ifuna i8.4V itshaja
Nokuba i-BMS ikhona, ukusebenzisa itshaja engahambelaniyo kugxininisa inkqubo. Ngelixa i-BMS inokungenelela, i-exposure overvoltage ephindaphindiweyo inokuwenza buthathaka amacandelo ayo ngokuhamba kwexesha
Ukuqukumbela
Iibhetri zeLithium zinamandla kodwa zibuthathaka. AiBMS ekumgangatho ophezulukubalulekile ukuqinisekisa ukhuseleko, ukusebenza kakuhle, kunye nobomi obude. Ngelixa inokukhusela okwexeshana kwitshaja enevoltage ephezulu, ukuxhomekeka koku kuyingozi. Soloko usebenzisa itshaja echanekileyo—ibhetri yakho (kunye nokhuseleko) iya kukubulela!
Khumbula: I-BMS ifana nebhanti lesihlalo. Ikhona ukukusindisa kwiimeko zikaxakeka, kodwa akufuneki uvavanye imida yayo!
