Ngesithuthi sombane esisulungekileyo

Iibhetri zamandla zenza iindleko eziphezulu

Ikwayinto ephambili echaphazela ubomi bebhetri

Kwaye intetho ethi "ukutshaja ngokukhawuleza" kuyayilimaza ibhetri

Ikwavumela abanini beemoto ezininzi zombane ukuba

kubangele amathandabuzo athile

Ngoko yintoni inyaniso?

01
Ukuqonda ngokuchanekileyo inkqubo "yokutshaja ngokukhawuleza".

Phambi kokuba siphendule lo mbuzo, sisenokwazi inkqubo “yokutshaja ngokukhawuleza”.Ukusuka ekufakeni umpu ukutshaja, amanyathelo amabini abonakala elula afihla uthotho lwamanyathelo ayimfuneko emva kwawo:

Xa intloko yompu yokutshaja ixhunywe ekupheleni kwesithuthi, imfumba yokutshaja iya kubonelela nge-low-voltage encedisayo ye-DC amandla ekupheleni kwesithuthi ukuze kusebenze i-BMS eyakhelwe ngaphakathi (inkqubo yokulawula ibhetri) yesithuthi sombane.Emva kokusebenza, ukuphela kwesithuthi kunye nokuphela kweemfumba zenza "isandla" ukutshintshisa iiparitha zokutshaja ezisisiseko ezifana namandla okuhlawula aphezulu afunekayo ekupheleni kwesithuthi kunye nobukhulu bokukhutshwa kwamandla okuphela kwemfumba.

Emva kokuba amaqela amabini efaniswe ngokuchanekileyo, i-BMS (inkqubo yolawulo lwebhetri) ekupheleni kwesithuthi iya kuthumela ulwazi lwemfuno yamandla kwimfumba yokutshaja, kwaye imfumba yokutshaja iya kulungelelanisa umbane wayo ophumayo kunye nowangoku ngokolwazi, kwaye iqalise ngokusemthethweni ukutshaja isithuthi.

“Ukutshaja ngokukhawuleza” akuyi konakalisa ibhetri

Akunzima ukufumanisa ukuba yonke inkqubo "yokutshaja ngokukhawuleza" kwezithuthi zombane ngokwenene yinkqubo apho isithuthi siphela kwaye isiphelo semfumba senza iparameter ehambelana nomnye, kwaye ekugqibeleni isiphelo semfumba sibonelela ngamandla okuhlawula ngokweemfuno. yokuphela kwesithuthi.Oku kufana nomntu onxaniweyo ofuna ukusela amanzi.Angakanani amanzi okusela kunye nesantya samanzi okusela kuxhomekeka ngakumbi kwiimfuno zomntu oselayo ngokwakhe.Ewe kunjalo, imfumba yokutshaja yeNkwenkwezi nayo inemisebenzi emininzi yokukhusela ukukhusela ukusebenza kwebhetri.Ngoko ke, ukuthetha ngokubanzi, "ukutshaja ngokukhawuleza" akuyi kulimaza ibhetri.

Kwilizwe lam, kukho imfuneko enyanzelekileyo kwinani lemijikelezo yeeseli zebhetri zamandla, ekufuneka zibe ngaphezu kwamaxesha e-1,000.Ukuthatha isithuthi sombane esinoluhlu lokuhamba ngeekhilomitha ezingama-500 njengomzekelo, ngokusekelwe kwimijikelezo ye-1,000 yokutshaja nokukhupha, kuthetha ukuba isithuthi sinokubaleka iikhilomitha ezingama-500,000.Ngokwesiqhelo, imoto yabucala ngokwesiseko iya kufika kuphela kwiikhilomitha ezingama-200,000 kumjikelo wobomi bayo.-Iikhilomitha ezingama-300,000 zoluhlu lokuqhuba.Ukubona oku, wena phambi kwesikrini useza kulwa “nokutshaja ngokukhawuleza”

Ukutshaja okunzulu kunye nokukhutshwa okunzulu, ukudibanisa ukutshaja okukhawulezayo kunye nokucothayo

Ngokuqinisekileyo, kubasebenzisi abaneemeko zokufakela iimfumba zokutshaja ekhaya, "ukutshaja okucothayo" ekhaya nako kulukhetho oluhle.Ngaphezu koko, kwimeko yesiboniso esifanayo kwi-100%, ubomi bebhetri "bentlawulo ephantsi" buya kuba malunga ne-15% ubude kunelo "lokukhawuleza ngokukhawuleza".Oku kubangelwa kukuba xa imoto "itshaja ngokukhawuleza", ikhoyo inkulu, ukushisa kwebhetri kuphakama, kwaye ukusabela kweekhemikhali zebhetri akwanelanga, okubangelwa inkohliso yentlawulo epheleleyo, ebizwa ngokuba yimali. "amandla abonakalayo".Kwaye "ukutshaja okucothayo" kuba okwangoku kuncinci, ibhetri inexesha elaneleyo lokuphendula, kwaye impembelelo incinci.

Ke ngoko, kwinkqubo yokutshaja yemihla ngemihla, unokukhetha ngokulula indlela yokutshaja ngokwemeko yokwenyani, kwaye ulandele umgaqo "wokutshaja okungekho nzulu kunye nokukhutshwa okunzulu, indibaniselwano yokutshaja okukhawulezayo nokucothayo".Ukuba ibhetri ye-lithium ye-ternary, kucetyiswa ukuba ugcine i-SOC yesithuthi phakathi kwe-20% -90%, kwaye akuyimfuneko ukuba ulandele ngamabomu i-100% intlawulo epheleleyo rhoqo.Ukuba ibhetri ye-lithium iron phosphate, kuyacetyiswa ukuba uyihlawule ubuncinane kanye ngeveki ukuze ulungise ixabiso le-SOC yesithuthi.
