Xa usakha i-Lithium-ion-ion-ion-ion, abantu abaninzi bayazibuza ukuba ngaba banokuxuba iiseli ezahlukeneyo zebhetri. Ngelixa kusenokubonakala kulula, ukwenjenjalo kunokukhokelela kwimiba eliqela, nokuba aInkqubo yoLawulo lwebhetri (ii-BMS)endaweni.
Ukuqonda le miceli mngeni kubalulekile ukuba nabani na ujonge ukudala ipakethi yebhetri ekhuselekileyo nethembekileyo.
Indima ye-BMS
I-BMS yinto ebalulekileyo kuyo nayiphi na ipakethi ye-lithium-ion. Eyona njongo yayo iphambili kukubeka iliso kwimpilo yebhetri kunye nokhuseleko.
I-BMS igcina umkhondo we-voltagesm nganye, amaqondo obushushu, kunye nentsebenzo yepakethi yebhetri. Ithintela nayiphi na iseli enye ukusuka kwindawo engaphezulu okanye yokukhupha ngaphezulu. Oku kunceda ukukhusela ukonakala kwebhetri okanye imililo.
Xa i-BMS ijonga i-voltage yeseli, ijonge iiseli ezisondeleyo kwi-voltage yabo ephezulu ngexesha lokutshaja. Ukuba ifumana enye, inokuyeka ukutshaja kwangoku kwiseli.
Ukuba iseli ikhutshiwe kakhulu, ii-BMS zinokukrola. Oku kuthintela umonakalo kwaye igcina ibhetri kwindawo yokusebenza ekhuselekileyo. La manyathelo okhuselo abalulekile ekugcineni ixesha lokuphila kunye nokhuseleko lwebhetri.
Iingxaki zokuxuba iiseli
Sebenzisa i-BMS inezibonelelo. Nangona kunjalo, ngokubanzi ayilombono ulungileyo wokuxuba iiseli ezahlukeneyo ze-IOIum-ion kwipakethi enye yebhetri.
Iiseli ezahlukeneyo zinokuba namandla ahlukeneyo, ukuxhathisa ngaphakathi, kunye nokuhlawula / amaxabiso egadi. Oku kungalingani kunokukhokelela kwezinye iiseli ezixineneyo ngokukhawuleza kunabanye. Nangona i-BMS inceda iliso lo mahluko, ayinakubabuyisa ngokupheleleyo.
Umzekelo, ukuba iseli enye inetyala elingaphantsi (SOC) kunabanye, iya kukhutshwa ngokukhawuleza. Ii-BMS zinokunqumla amandla okukhusela eso seli, kwanaxa ezinye iiseli zisenetyala elishiywe. Le meko ingakhokelela ekukhathazekeni kwaye inciphise ukusebenza kwepakethi yebhetri, ukusebenza kweflethi.
Umngcipheko wokhuseleko
Ukusebenzisa iiseli ze-mismatring kuseyifaka umngcipheko wokhuseleko. Nokuba i-BMS, esebenzisa iiseli ezahlukileyo kunye enyusa ukubakho kwemicimbi.
Ingxaki kwiseli enye inokuba nefuthe kwipakethe yonke. Oku kunokubangela imiba eyingozi, njengokurhangqa i-thermal okanye iisekethe ezifutshane. Ngelixa i-BMS iphucula ukhuseleko, ayinakuphelisa yonke imingcipheko enxulumene nokusebenzisa iiseli ezingahambelaniyo.
Ngamanye amaxesha, ii-BMs zinokuthintela ingozi, efana nomlilo. Nangona kunjalo, ukuba umsitho wonakalisa i-BMS, isenokungasebenzi kakuhle xa umntu efumana ibhetri. Oku kungashiya ibhetri yebhetri esengozini kwimingcipheko yexesha elizayo kunye nokusilela kwenkonzo.
Ukuqukumbela, i-BMS ibalulekile ekugcineni i-lithium-ion-ion-ion-ion ikhuselekile kwaye iqhuba kakuhle. Nangona kunjalo, kusekungcono ukusebenzisa iiseli ezifanayo kumvelisi ofanayo kunye nebhetshi. Ukuxuba iiseli ezahlukeneyo kunokukhokelela ekungalinganiyo, ukusebenza okuncitshisiweyo, kunye neengozi zokhuseleko ezinokubakho. Kuba nabani na ojonga ukwenza inkqubo yebhetri ethembekileyo nekhuselekileyo, ukutyala imali kwiiseli ezifanayo.
Sebenzisa iiseli ze-lithium efanayo kunceda ukusebenza kunye nokunciphisa umngcipheko. Oku kuqinisekisa ukuba uziva ukhuselekile ngelixa usebenza ipakethe yebhetri yakho.
