Njengendawo apho ukusabela kwenzeka khona, iisitaki vanadiumyahlulwe kwitanki yokugcina yokugcina i-electrolyte, eyona nto yoyisa i-self-discharge phenomenon yeebhetri zemveli. Amandla axhomekeke kuphela kubungakanani be-stack, kwaye umthamo uxhomekeke kuphela kwisitoreji se-electrolyte kunye nokugxila. Uyilo lubhetyebhetye kakhulu; xa amandla ehlala ehlala, ukwandisa amandla okugcina amandla, kuyimfuneko kuphela ukwandisa umthamo wetanki yokugcina i-electrolyte okanye ukwandisa umthamo okanye ugxininiso lwe-electrolyte. Ewe, ngaphandle kokutshintsha ubungakanani besitaki; injongo "yokutshaja kwangoko" inokufezekiswa ngokutshintsha okanye ukongeza i-electrolyte kwimeko yokuhlawula. Ingasetyenziselwa ukwakha i-kilowatt-level ukuya kwi-100-megawatt enerizikhululo zamandla zokugcina i-gy, ezinokuguquguquka okuqinileyo.
VRFBunomlinganiselo omkhulu wenkululeko ekukhetheni indawo kwaye uhlala kumhlaba omncinci. Inkqubo inokuvalwa ngokupheleleyo kwaye isebenze ngaphandle kwenkungu ye-asidi kunye nokubola kwe-asidi. I-electrolyte ingaphinda isetyenziswe, akukho kukhutshwa, ukugcinwa okulula kunye neendleko zokusebenza eziphantsi. Yiteknoloji yokugcina amandla aluhlaza. Ke ngoko, ukuvelisa amandla avuselelekayo, iibhetri ze-vanadium zezona ndawo zifanelekileyo endaweni yeebhetri ze-lead-acid.
Ibhetri yeVanadiumiimpawu ubomi benkqubo ende. Ukusebenza kwenkqubo kuphezulu. Ukusebenza komjikelo wenkqubo yebhetri ye-vanadium inokufikelela kwi-65-80%. Ukuxhasa ukutshaja rhoqo kunye nokukhupha. Iibhetri zeVanadium zixhasa rhoqo ukutshaja okuphezulu-yangoku kunye nokukhupha, kwaye inokutshajwa kwaye ikhutshwe kakhulu ngamaxesha ngosuku ngaphandle kokunciphisa umthamo webhetri. Ixhasa i-overcharge kunye ne-overdischarge. Inkqubo yebhetri ye-vanadium isekela intlawulo enzulu kunye nokukhutshwa (DOD 80%) ngaphandle kokulimaza ibhetri. Umlinganiselo wentlawulo-ukukhutshwa ngu-1.5: 1. Inkqubo yebhetri ye-vanadium inokubona intlawulo ekhawulezayo kunye nokukhutshwa ukuze ihlangabezane neemfuno zomthwalo. Izinga eliphantsi lokuzikhupha. Izinto ezisebenzayo kwi-electrolytes emihle kunye nembi yeiibhetri vanadiumzigcinwa kwiitanki ezahlukeneyo. Kwindlela yokuvala inkqubo, i-electrolyte kwitanki ayinayo into yokuzikhupha.
Ukuqalisa kuyakhawuleza. Ngexesha lokusebenza kweinkqubo yebhetri yevanadium, ukutshaja kunye nexesha lokukhupha lingaphantsi kwe-1 millisecond / uyilo lwenkqubo yebhetri luguquguqukayo. Amandla kunye nomthamo wenkqubo yebhetri ye-vanadium inokuqulunqwa ngokuzimeleyo kwaye iqwalaselwe ngokweemfuno zabathengi ukufezekisa ukuphuculwa ngokukhawuleza. Iindleko zokulungisa eziphantsi. Inkqubo yebhetri ye-vanadium iqonda ukusebenza okuzenzekelayo ngokupheleleyo, iindleko eziphantsi zokusebenza, ixesha elide lokugcinwa kunye nokugcinwa okulula. Iyahambelana nokusingqongileyo kwaye ayinangcoliseko. Inkqubo yebhetri ye-vanadium ivaliwe kwindawo yokushisa kwaye ihlangabezana neemfuno zokusingqongileyo. Inokubuyiselwa ngokupheleleyo ngaphandle kwayo nayiphi na imiba yokulahlwa.
