Kwisithuthi sombane esicocekileyo

Iibhetri zamandla zezona ndleko ziphezulu

Kwakhona yinto ephambili echaphazela ubomi bebhetri

Kwaye intetho ethi "ukutshaja ngokukhawuleza" kuyayilimaza ibhetri

Ikwavumela abanini beemoto ezininzi zombane ukuba

iphakamise amathandabuzo athile

Ngoko ke yintoni inyaniso?

01
Ukuqonda ngokuchanekileyo inkqubo "yokutshaja ngokukhawuleza"

Ngaphambi kokuba siphendule lo mbuzo, singatsho sazi inkqubo "yokutshaja ngokukhawuleza". Ukususela ekufakeni umpu ukuya ekutshajeni, la manyathelo mabini abonakala elula afihla uthotho lwamanyathelo ayimfuneko emva kwawo:

Xa intloko yesibhamu sokutshaja iqhagamshelwe kwisiphelo sesithuthi, inqwaba yokutshaja iya kubonelela ngamandla e-DC ancedisayo ane-voltage ephantsi kwisiphelo sesithuthi ukuze kusebenze i-BMS eyakhelwe ngaphakathi (inkqubo yolawulo lwebhetri) yesithuthi sombane. Emva kokuvula, isiphelo sesithuthi kunye nesiphelo senqwaba zenza "ukuxhawulana" ukuze kutshintshiselwane iiparamitha zokutshaja ezisisiseko ezifana namandla aphezulu okutshaja afunekayo kwisiphelo sesithuthi kunye namandla aphezulu okukhupha kwisiphelo senqwaba.

Emva kokuba amaqela omabini efaniswe ngokuchanekileyo, i-BMS (inkqubo yolawulo lwebhetri) ekupheleni kwesithuthi iya kuthumela ulwazi lwemfuno yamandla kwinqwaba yokutshaja, kwaye inqwaba yokutshaja iya kulungisa i-voltage yayo yokuphuma kunye nombane ngokweenkcukacha, kwaye iqalise ngokusesikweni ukutshaja imoto.

"Ukutshaja ngokukhawuleza" akuyi kuyonakalisa ibhetri

Akunzima ukufumanisa ukuba yonke inkqubo "yokutshaja ngokukhawuleza" kwezithuthi zombane yinkqubo apho isiphelo sesithuthi kunye nesiphelo senqwaba zihambelana khona, kwaye ekugqibeleni isiphelo senqwaba sibonelela ngamandla okutshaja ngokweemfuno zesiphelo sesithuthi. Oku kufana nomntu onxaniweyo kwaye ofuna ukusela amanzi. Ubungakanani bamanzi okusela kunye nesantya samanzi okusela kuxhomekeke ngakumbi kwiimfuno zomseli ngokwakhe. Kakade ke, inqwaba yokutshaja yeStar Charging ngokwayo ikwanazo nemisebenzi emininzi yokukhusela ukusebenza kwebhetri. Ke ngoko, ngokubanzi, "ukutshaja ngokukhawuleza" akuyi kuyenzakalisa ibhetri.

Kwilizwe lam, kukwakho nemfuneko enyanzelekileyo yenani leebhayisekile zamandla, ekufuneka zibe ngaphezulu kwe-1,000 amaxesha. Umzekelo, xa sijonga imoto yombane enomgama wokuhamba ngeenyawo oziikhilomitha ezingama-500, ngokusekelwe kwimijikelo yokutshaja nokukhupha itshaja eyi-1,000, oko kuthetha ukuba imoto inokubaleka iikhilomitha ezingama-500,000. Ngokwesiqhelo, imoto yabucala iya kufikelela kuphela kwiikhilomitha ezingama-200,000 kumjikelo wayo wobomi. -300,000 iikhilomitha zomgama wokuqhuba. Ukubona oku, phambi kwesikrini uya kuba nengxaki "yokutshaja ngokukhawuleza"

Ukutshaja okungenzulu kunye nokukhupha okungenzulu, okudibanisa ukutshaja okukhawulezayo nokucothayo

Kakade ke, kubasebenzisi abaneemeko zokufaka ii-piles zokutshaja ekhaya, "ukutshaja kancinci" ekhaya nako kukhetho olufanelekileyo. Ngaphezu koko, kwimeko yesiboniso esifanayo kwi-100%, ubomi bebhetri "bokutshaja kancinci" buya kuba malunga ne-15% ubude kunobo "bokutshaja ngokukhawuleza". Oku kungenxa yokuba xa imoto "itshaja ngokukhawuleza", umbane mkhulu, ubushushu bebhetri buyanyuka, kwaye impendulo yekhemikhali yebhetri ayanelanga, nto leyo ebangela umbono wokuba itshaja epheleleyo, okubizwa ngokuba "ngamandla abonakalayo". Kwaye "ukutshaja kancinci" kuba umbane mncinci, ibhetri inexesha elaneleyo lokuphendula, kwaye impembelelo incinci.

Ngoko ke, kwinkqubo yokutshaja yemihla ngemihla, ungakhetha ngokuguquguquka indlela yokutshaja ngokwemeko yokwenyani, kwaye ulandele umgaqo "wokutshaja okuncinci kunye nokukhupha okuncinci, indibaniselwano yokutshaja ngokukhawuleza nangokucothayo". Ukuba yibhetri ye-lithium yesithathu, kucetyiswa ukuba igcine i-SOC yesithuthi phakathi kwe-20%-90%, kwaye akufuneki ukuba ufune ngabom ukutshaja okupheleleyo nge-100% ngalo lonke ixesha. Ukuba yibhetri ye-lithium iron phosphate, kucetyiswa ukuba uyitshaje ubuncinane kanye ngeveki ukuze kulungiswe ixabiso le-SOC yesithuthi.
