Xa ukwakhiwa kwebhetri ye-lithium-ion, abantu abaninzi bayazibuza ukuba banokuxuba iiseli zebhetri ezahlukeneyo. Nangona kusenokubonakala kuluncedo, ukwenza oko kunokukhokelela kwimiba emininzi, nkqu neInkqubo yoLawulo lwebhetri (BMS)endaweni.
Ukuqonda le mingeni kubalulekile kuye nabani na ojonge ukwenza ipakethi yebhetri ekhuselekileyo nethembekileyo.
Indima ye-BMS
I-BMS yinxalenye ebalulekileyo yayo nayiphi na ipakethe yebhetri ye-lithium-ion. Eyona njongo iphambili kukubeka iliso rhoqo kwimpilo yebhetri kunye nokhuseleko.
I-BMS igcina umkhondo wee-voltages zeseli nganye, amaqondo obushushu, kunye nokusebenza iyonke yebhetri yepakethe. Ikhusela nayiphi na iseli enye ekutshajisweni okanye ukukhupha ngaphezulu. Oku kunceda ukuthintela ukonakala kwebhetri okanye imililo.
Xa i-BMS ijonga i-voltage yeseli, ijonga iiseli ezikufutshane nowona mbane uphezulu ngexesha lokutshaja. Ukuba ifumene enye, inokumisa umsinga wokutshaja kuloo seli.
Ukuba iseli ikhupha kakhulu, iBMS inokuyiqhawula. Oku kuthintela umonakalo kwaye igcina ibhetri kwindawo ekhuselekileyo yokusebenza. La manyathelo okhuselo abalulekile ekugcineni ubomi bebhetri kunye nokhuseleko.
Iingxaki ngokuxuba iiseli
Ukusebenzisa i-BMS kunenzuzo. Nangona kunjalo, ayilombono ilungileyo ukuxuba iiseli ze-lithium-ion ezahlukeneyo kwipakethi yebhetri efanayo.
Iiseli ezahlukeneyo zinokuba namandla ahlukeneyo, ukuchasana kwangaphakathi, kunye namazinga okuhlawula / okukhupha. Oku kungalingani kunokukhokelela ekubeni ezinye iiseli ziguge ngokukhawuleza kunezinye. Nangona i-BMS inceda ukubeka esweni ezi yantlukwano, isenokungababuyekezeli ngokupheleleyo.
Umzekelo, ukuba iseli enye inesimo esisezantsi sentlawulo (SOC) kunezinye, iya kukhupha ngokukhawuleza. I-BMS inokuwacima amandla okukhusela loo seli, naxa ezinye iiseli zisene charge eshiyekileyo. Le meko inokukhokelela ekukhungathekeni kwaye inciphise ukusebenza kakuhle kwebhetri ipakethe, ifuthe ukusebenza.
Imingcipheko yoKhuseleko
Ukusebenzisa iiseli ezingahambelaniyo nako kubangela imingcipheko yokhuseleko. Nokuba nge-BMS, ukusebenzisa iiseli ezahlukeneyo kunye kwandisa amathuba okuba nemiba.
Ingxaki kwiseli enye inokuchaphazela yonke ipakethi yebhetri. Oku kunokubangela imiba eyingozi, njengokubaleka kwe-thermal okanye iisekethe ezimfutshane. Ngelixa i-BMS iphucula ukhuseleko, ayinakukwazi ukuphelisa zonke iingozi ezinxulumene nokusebenzisa iiseli ezingahambelaniyo.
Kwezinye iimeko, i-BMS inokuthintela ingozi ekhawulezileyo, enjengomlilo. Nangona kunjalo, ukuba isiganeko sonakalisa i-BMS, isenokungasebenzi kakuhle xa umntu eqala ngokutsha ibhetri. Oku kunokushiya ipakethi yebhetri isengozini kwimingcipheko yexesha elizayo kunye nokusilela ekusebenzeni.
Ukuqukumbela, i-BMS ibalulekile ekugcineni ibhetri ye-lithium-ion ikhuselekile kwaye iqhuba kakuhle. Nangona kunjalo, kusengcono ukusebenzisa iiseli ezifanayo ukusuka kumenzi ofanayo kunye nebhetshi. Ukudibanisa iiseli ezahlukeneyo kunokukhokelela ekungalinganini, ukunciphisa ukusebenza, kunye nobungozi obunokhuseleko. Nabani na ojonge ukwenza inkqubo yebhetri ethembekileyo nekhuselekileyo, ukutyala imali kwiiseli ezifanayo kububulumko.
Ukusebenzisa iiseli ze-lithium-ion ezifanayo kunceda ukusebenza kunye nokunciphisa ingozi. Oku kuqinisekisa ukuba uziva ukhuselekile ngelixa usebenzisa ipakethi yebhetri yakho.
