Iibhetri zeLithium zisetyenziswe ngokubanzi kwizixhobo ezinjengeSmartPhones, izithuthi zombane, kunye neenkqubo zamandla elanga. Nangona kunjalo, ebamangalisa ngokungachanekanga banokukhokelela kwiingozi zokhuseleko okanye ukonakala okungapheliyo.
WUCh usebenzisa i-charger ye-charger ephezulu kakhulu kwayeInkqubo yolawulo lwebhetri (i-BMS) ikhusela njani i-lithium Barts?
Ingozi yokuphambuka
Iibhetri zeLithium zinemida engqongqo ye-voltage. Umzekelo:
.AI-Wildpo4(I-Lithium ye-iron i-phosphate) Iseli inesisu esithile se3.2Vkwaye kufunekaUngaze udlule kwi-3.65VXa ihlawulisiwe ngokupheleleyo
.ALi-ion(I-Lithium Coballt) iseli, ixhaphakile kwiifowuni, isebenza kwi3.7Vkwaye kufuneka ihlale ingezantsi4.2V
Sebenzisa itshaja kunye ne-voltage ephezulu kunomda webhetri kumandla amakhulu kwiiseli. Oku kunokubangelaukugcwala,ukudumba, okanyeI-thermal ebalekayo-Ukuba nendlela eyingozi yokuphendula apho ibhetri ibambisa umlilo okanye iqhume
I-BMS igcina njani imini
Inkqubo yolawulo lwebhetri (ii-BMS) isebenza njenge "mgadi" kwiibhetri zeLithium. Nantsi indlela isebenza ngayo:
1.Ulawulo lwevolthi
I-BMS ibeka iliso kwi-voltage nganye yeseli. Ukuba i-charger yevolthi ephezulu ixhunyiwe, i-BMS ichonge i-overvollic kwayesusa isekethe yokutshajaUkuthintela umonakalo
2.Ummiselo wobushushu
Ukubiza ngokukhawuleza okanye ukuhambisa ngaphezulu ubushushu. I-BMS Tracks iqondo lokushisa kwaye linciphise isantya sokutshaya okanye siyeke ukubiza ukuba ibhetri ishushu kakhulu113.
3.Ukulungelelaniswa kweseli
Kwiibhetri ezinamaphepha amaninzi (njenge-12v okanye iipakethi ze-24v okanye iiseli ze-24V), ezinye iiseli zinetyala ngokukhawuleza kunabanye. I-BMS ihlaziyiwe amandla okuqinisekisa ukuba zonke iiseli zifikelela kwi-voltage efanayo, ukuthintela ukukhonkxa kwiiseli ezomeleleyo
4.Ukhuseleko lokhuseleko
Ukuba i-BMS ichonga imiba ebalulekileyo efana nokugqitha kakhulu okanye i-voltage spikes, inqamle ibhetri isebenzisa ngokupheleleyo izinto ezifanaMosfets(switch ye-elektroniki) okanyezabasebenzi(Umatshini wokudlulisela)
Indlela eyiyo yokubiza i-lithium Bit
Soloko usebenzisa itshajaUkutshatisa i-voltage yakho kunye ne chemistry.
Umzekelo:
Ibhetri ye-12V yobomi be-12v (iiseli ezi-4 kwingcelele) ifuna itshaja nge14.6V Iziphumo(4 × 3.65v)
Ipakethi ye-7.4v lion (iiseli ezi-2) ifuna8.4Vger
Nokuba ii-BMs zikhona, zisebenzisa i-chags engahambelaniyo ichasisa inkqubo. Ngelixa i-BMS inokungenelela, ukuvezwa okungaphezulu kwe-overvlllige kunokubangela izinto zayo ngokuhamba kwexesha
Ukuqukumbela
Iibhetri zeLithium zinamandla kodwa zibuthathaka. AI-BMS ephezuluKubalulekile ukuqinisekisa ukhuseleko, ukusebenza kakuhle, kunye nobomi obude. Ngelixa kunokukhusela okwethutyana nxamnye ne-chagger ye-chagger, ethembela koku kuyingozi. Soloko usebenzisa itshaja echanekileyo-ibhetri yakho (kunye nokhuseleko) uya kubulela!
Khumbula: I-BMS ifana nesihlalo. Kukwakusindisa ngexesha likaxakeka, kodwa akufuneki uvavanye umda wayo!
