Kwihlabathi elikhula ngokukhawuleza leebhetri, i-Lithium Iron Phosphate (LFP) ifumene i-traction ebalulekileyo ngenxa yeprofayili yayo yokhuseleko oluhle kunye nobomi bomjikelezo omde. Ukanti, ukulawula le mithombo yamandla ngokukhuselekileyo kuhlala kungundoqo. Embindini wolu khuseleko kukho iNkqubo yoLawulo lweBattery, okanye iBMS. Olu khuseleko lwesekethe lunobugocigoci, ludlala indima ebalulekileyo, ngakumbi ekuthinteleni iimeko ezimbini ezinokuthi zibe yingozi kwaye zibe yingozi: ukhuseleko lwe-charge, kunye nokhuseleko lokukhutshelwa ngaphezulu. Ukuqonda ezi ndlela zokhuseleko lwebhetri yeyona nto ibalulekileyo kuye nabani na oxhomekeke kwitekhnoloji ye-LFP yokugcina amandla, nokuba kukuseto lwasekhaya okanye kwiinkqubo ezinkulu zebhetri.
Kutheni uKhuseleko lweTshatshi ePhakamileyo ibalulekile kwiibhetri zeLFP
Ukutshaja kakhulu kwenzeka xa ibhetri iqhubeka nokufumana amandla angaphaya kwemeko yayo yokutshaja ngokupheleleyo. Kwiibhetri ze-LFP, oku kungaphezulu nje komcimbi osebenzayo-yingozi yokhuseleko. Ukugqithiswa kwamandla ombane ngexesha lokutshaja kakhulu kunokukhokelela koku:
- Ukunyuka kwamaqondo obushushu okukhawulezayo: Oku kukhawulezisa ukuwohloka kwaye, kwiimeko ezinzima, kunokuqalisa ukubaleka kwe-thermal.
- Ukwakhiwa koxinzelelo lwangaphakathi: Ukubangela ukuvuza okunokwenzeka kwe-electrolyte okanye nokukhupha umoya.
- Ukulahleka komthamo ongenakubuyiseka: Ukonakalisa ubume bangaphakathi bebhetri kunye nokwenza bufutshane ubomi bebhetri.
I-BMS iyayilwa le nto ngokubeka iliso kumbane oqhubekayo. Ilandelela ngokuchanekileyo amandla ombane weseli nganye nganye ngaphakathi kwepakethi isebenzisa abenzi boluvo basebhodini. Ukuba nayiphi na i-voltage yeeseli inyuke ngaphaya komda okhuselekileyo omiselweyo, i-BMS isebenza ngokukhawuleza ngokuyalela ukuba kunqandwe intlawulo yesekethe. Oku kuqhawulwa kwangoko kwamandla okutshaja yeyona nto ikhuselayo ngokuchasene nokutshaja, ukuthintela ukusilela okuyintlekele. Ukongeza, izisombululo ze-BMS ezihambele phambili zibandakanya ii-algorithms zokulawula inqanaba lokutshaja ngokukhuselekileyo.
Indima ebalulekileyo yoThintelo lokuKhupha ngokuPheleleyo
Ngokwahlukileyo, ukukhupha ibhetri ngokunzulu kakhulu-ngaphantsi kwendawo ekhuthazwayo yokuqhawula i-voltage-kukwabeka ingozi enkulu. Ukukhutshwa okunzulu kwiibhetri ze-LFP kunokubangela:
- Umthamo omkhulu uyaphela: Ukukwazi ukubamba intlawulo epheleleyo kuncipha kakhulu.
- Ukungazinzi kweekhemikhali zangaphakathi: Ukwenza ibhetri ingakhuselekanga ukutshajwa kwakhona okanye ukusetyenziswa kwixesha elizayo.
- Ukuguqulwa kweeseli ezinokwenzeka: Kwiipakethe zeeseli ezininzi, iiseli ezibuthathaka zinokuqhutywa kwi-polarity eguqukayo, ibangele umonakalo osisigxina.
Apha, i-BMS isebenza njengomgcini ophaphileyo kwakhona, ngokuyintloko ngokujongwa okuchanekileyo kwemeko yokutshaja (i-SOC) okanye ukufumanisa umbane ophantsi. Ilandelela ngokusondeleyo amandla akhoyo ebhetri. Njengoko inqanaba lombane layo nayiphi na iseli lisondela kumda obalulekileyo we-voltage ephantsi, i-BMS ixhokonxa i-discharge circuit cutoff. Oku kumisa ngoko nangoko ukutsalwa kwamandla kwibhetri. Olunye ulwakhiwo lwe-BMS olunobugocigoci lukwaphumeza amacebo okucinywa komthwalo, ngobuhlakani ukunciphisa imijelo yamandla engabalulekanga okanye ukungena kwimowudi yamandla asezantsi ebhetri, ukwandisa ukusebenza okuncinci okubalulekileyo kunye nokukhusela iiseli. Le ndlela yokuthintela ukukhutshwa nzulu, ibalulekile ekwandiseni ubomi bomjikelo webhetri, kunye nokugcina ukuthembeka kwenkqubo iyonke.
Ukhuseleko oluDityanisiweyo: UMongo woKhuseleko lwebhetri
Ukhuseleko lokuchasa ngokugqithisileyo kunye nokukhutshwa ngokugqithisileyo ayingomsebenzi omnye kodwa sisicwangciso esidityanisiweyo ngaphakathi kweBMS eyomeleleyo. Iinkqubo zolawulo lwebhetri zale mihla zidibanisa ukusetyenzwa kwesantya esiphezulu kunye nee-algorithms ezintsonkothileyo zombane wexesha lokwenyani kunye nokulandela umkhondo wangoku, ukujonga ubushushu, kunye nolawulo oluguqukayo. Le ndlela yokhuseleko olupheleleyo lwebhetri iqinisekisa ukufunyanwa ngokukhawuleza kunye nenyathelo elikhawulezileyo ngokuchasene neemeko ezinokuba yingozi. Ukukhusela utyalo-mali lwakho lwebhetri kuxhomekeke kwezi nkqubo zolawulo zikrelekrele.
