Iibhetri zeLithium-ionziye zaxhaphaka kubomi bemihla ngemihla.Zikuyo yonke indawo, ukusuka kwii-smartphones ukuya kwiilaptops, izithuthi zombane ukuya kwiibhanki zamandla.Ezi bhetri zisebenza kakuhle, zixinene, kwaye ziyakwazi ukugcina amandla.Nangona kunjalo, ngala mandla kuza uxanduva.Ulawulo olululo kunye nokhuseleko olufanelekileyo luyimfuneko xa kuziwa kwiibhetri ze-lithium-ion.
Enye inxalenye ebalulekileyo yokhuseleko kunye nokusebenza kweebhetri ze-lithium-ion yiNkqubo yoLawulo lweBattery (BMS).I-BMS ibeka iliso kwaye ilawule ukutshajiswa kwebhetri, ukukhutshwa, ubushushu kunye nombane kwaye ikhusela ibhetri ekutshajisweni, ekukhutshweni kakhulu, nakwiisekethe ezimfutshane.Kweli nqaku, siza kugxila kwindlela yokusebenzisa i-4s Li-ion lithium 18650 ibhetri ye-BMS ipakethe ibhodi yokukhusela ye-PCB.
Yintoni i-4s Li-ion lithium 18650 ibhetri ye-BMS ipakethe ibhodi yokukhusela ye-PCB?
I-4s Li-ion lithium 18650 ibhetri ye-BMS ipakisha ibhodi yokukhusela i-PCB yibhodi yesekethe encinci eyenzelwe ukukhusela ibhetri kwiingozi ezahlukeneyo ezifana nokugqithisa, ukukhutshwa ngokugqithiseleyo, iisekethe ezimfutshane, kunye nokutshintsha kweqondo lokushisa.Le bhodi ineyunithi yokulawula i-micro-controller (MCU), iiswitshi ze-MOSFET, izixhasi, ii-capacitors, kunye namanye amacandelo asebenza kunye ukujonga amandla ombane webhetri kunye namanqanaba angoku kunye nokulawula ukutshajiswa nokukhupha ibhetri.
I-"4s" egameni le-BMS ibhekiselele kwinani leeseli ezikwipakethi yebhetri.I-18650 ibhekisela kubukhulu beeseli ze-lithium-ion.Iseli ye-18650 yiseli ye-lithium-ion eyicylindrical elinganisa i-18mm ububanzi kunye ne-65mm ubude.
Kutheni usebenzise i-4s Li-ion lithium 18650 ibhetri ye-BMS ipakethe ibhodi yokukhusela ye-PCB?
Ukusebenzisa i-4s Li-ion lithium 18650 ibhetri ye-BMS ipakethe ibhodi yokukhusela i-PCB ibalulekile kuba iqinisekisa ukusetyenziswa okukhuselekileyo nokusebenzayo kwebhetri.I-BMS yenzelwe ukunqanda ibhetri ekutshajisweni, ukukhupha kakhulu, kunye nokutshisa kakhulu.Ukutshaja ngokugqithisileyo kunye nokukhupha ngokugqithisileyo kunokukhokelela kumonakalo ongalungisekiyo kwibhetri, kunciphise ubomi bayo, kwaye kude kubangele umlilo okanye ugqabhuko-dubulo.
Ngaphezu koko, i-BMS inoxanduva lokulinganisa iiseli kwipakethi yebhetri.Iiseli ze-lithium-ion zinoluhlu lwamandla ombane olulinganiselweyo, kwaye ukuba iseli enye itshajiswe kakhulu okanye itshajiswe ngaphantsi, inokuchaphazela ukusebenza ngokubanzi kunye nokhuseleko lwepakethi yebhetri.I-BMS iqinisekisa ukuba zonke iiseli ezikwipakethi yebhetri zitshajiwe kwaye zikhutshwa ngokulinganayo, kwandisa ixesha lokuphila kwebhetri.
Indlela yokusebenzisa i-4s Li-ion lithium 18650 ibhetri ye-BMS ipakethe ibhodi yokukhusela yePCB?
Ukusebenzisa i-4s Li-ion lithium 18650 ibhetri ye-BMS ipakethe ibhodi yokukhusela i-PCB kulula kwaye ayifuni izakhono ezikhethekileyo okanye izixhobo.Nangona kunjalo, kubalulekile ukulandela imiyalelo yomenzi ngononophelo ukuqinisekisa ukhuseleko kunye nokusetyenziswa ngokufanelekileyo kwebhetri.
Nanga amanyathelo okusebenzisa i-4s Li-ion lithium 18650 ibhetri ye-BMS ipakethe ibhodi yokukhusela yePCB:
Inyathelo 1: Qokelela amacandelo
Ngaphambi kokuba uqale ukudibanisa ipakethi yebhetri, kufuneka uqokelele zonke izinto ozifunayo.Oku kuquka iiseli ze-18650, ibhodi yeBMS, isibambi sebhetri, iingcingo, kunye nentsimbi yokuthambisa.
Inyathelo 2: Lungisa iiseli
Hlola iseli nganye ukuze uqiniseke ukuba ayonakaliswa okanye awonakalanga.Emva koko, vavanya i-voltage yeseli nganye usebenzisa i-multimeter.Iiseli kufuneka zibe namanqanaba ombane afanayo.Ukuba naziphi na iiseli zinenqanaba lombane elahluke kakhulu, isenokuba luphawu lokuba iseli yonakele okanye isetyenziswe ngokugqithisileyo.Faka endaweni yazo naziphi na iiseli ezonakeleyo okanye ezingalunganga.
Inyathelo 3: Hlanganisa ibhetri
Faka iiseli kwisibambi sebhetri, uqinisekise ukuba i-polarity ichanekile.Emva koko, qhagamshela iiseli kuthotho.
