Iindaba - Ukhuseleko lwe-BMS Overload kunye ne-Short Circuit yoKhuseleko lweBhetri yasekhaya

Njengoko iinkqubo zokugcina umbane emakhaya zisanda, iingxaki zokhuseleko malunga nolawulo lweebhetri ziya zisanda. Intliziyo yezi nkqubo ikwimeko entle.iInkqubo yoLawulo lweeBhetri (i-BMS), into ebalulekileyo eyilelwe ukuthintela iziganeko ezinobungozi ezifana nokugqithisa kakhulu kunye neesekethe ezimfutshane. Kubanini bezindlu, ukuqonda indlela esebenza ngayo itekhnoloji ye-BMS kunokuthetha umahluko phakathi kogcino lwamandla oluthembekileyo kunye nomngcipheko wokhuseleko onokubakho.

Ukuqonda iingozi zomthwalo ogqithisileyo kunye neengozi zesekethe ezimfutshane

Iibhetri zokugcina amandla ekhaya, ingakumbi iipakethe ze-lithium-ion, zisengozini yokugcwala kakhulu (ukutsalwa kwamandla agqithisileyo) kunye neesekethe ezimfutshane (ukuhamba kwamandla angqalileyo phakathi kwee-terminals ezilungileyo nezingalunganga). Ezi ziganeko zinokubangela ubushushu obukhulu, okukhokelela ekubalekeni kobushushu, imililo, okanye nokuqhuma.I-BMSIsebenza njengomgca wokuqala wokhuselo, ibeka esweni rhoqo i-voltage, i-current, kunye nobushushu.

Iindlela zoKhuselo lweeLayelo ezininzi

Ukubeka esweni okwangoku ngexesha langempela lokuthintela ukulayisha kakhulu:II-BMSIsebenzisa izinzwa zamandla ombane ezichanekileyo kakhulu ukulandelela ukuhamba kombane ngaphakathi nangaphandle kwebhetri. Icwangciswe ngemida yamandla ombane ekhuselekileyo ngokusekelwe kwiinkcukacha zebhetri. Ukuba inkqubo ibona ukutsalwa kwamandla ombane okugqitha le mida ichazwe kwangaphambili—umzekelo, xa izixhobo ezininzi zamandla aphezulu zisebenza ngaxeshanye—I-BMSiya kuyalela ngoko nangoko iiMOSFET (iiswitshi ze-elektroniki) ukuba zivule isekethe. Oku kunciphisa ukuhamba kwamandla ngaphakathi kwee-millisecond, okuthintela iiseli zebhetri ekubeni zitshise kakhulu kwaye zonakale.ukhuseleko olugqithisileyoKubalulekile ukwandisa ubomi bebhetri.

Impendulo Ekhawulezileyo Kwimijikelezo Emfutshane:I-short circuit inokubangela ukuba umbane unyuke uye kumanqanaba aphezulu ngokuyingozi phantse ngephanyazo.I-BMSyenzelwe ngesixhobo esikhethekileyoukhuseleko lwesekethe emfutshaneUphawu olunexesha lokuphendula elikhawulezayo kunokhuseleko lokugqithisa. Isebenzisa ii-algorithms eziphambili, inokuqaphela ukuhla kwe-voltage yesekethe emfutshane kwaye ikhuphe ibhetri kwi-microseconds. Olu tshintsho lukhawulezileyo lubalulekile ekuthinteleni ukungaphumeleli okubi kwaye luyimigangatho yokhuseleko engenakuphikiswana ngayo kwimihla yanamhlanje.izisombululo zokugcina umbane ekhaya.

Ulawulo oluHlanganisiweyo lweThermal:Ukugqithisa kunye neesekethe ezimfutshane kuvelisa ubushushu obukhulu.I-BMSIsebenza ngokubambisana nezinzwa zobushushu eziqhotyoshelwe kwiiseli zebhetri. Ukuba amaqondo obushushu enyuka ngaphaya komgangatho wokusebenza okhuselekileyo, nangaphambi kokuba kubhengezwe umthwalo omkhulu ngokusemthethweni,I-BMSinokunciphisa umbane ovumelekileyo ngaphambi kwexesha okanye ikhuphe ibhetri ngokupheleleyo. Oku kuyasebenzaulawulo lobushushuyongeza umaleko obalulekileyo wokhuseleko.
