Njengendawo lapho ukusabela kwenzeka khona, iisitaki vanadiumihlukaniswe nethangi lokugcina ukuze kugcinwe i-electrolyte, enqoba ngokuyisisekelo umkhuba wokuzikhulula wamabhethri endabuko. Amandla ancike kuphela kusayizi wesitaki, futhi umthamo uncike kuphela ekugcinweni kwe-electrolyte nokugxila. Umklamo uvumelana nezimo kakhulu; lapho amandla ehlala njalo, ukwandisa umthamo wokugcina amandla, kudingekile kuphela ukwandisa umthamo wethangi lokugcina i-electrolyte noma ukwandisa ivolumu noma ukuhlushwa kwe-electrolyte. Yebo, ngaphandle kokushintsha usayizi wesitaki; inhloso "yokushaja okusheshayo" ingafinyelelwa ngokufaka esikhundleni noma ngokungeza i-electrolyte esimweni sokushaja. Ingasetshenziselwa ukwakha i-kilowatt-level ukuya ku-100-megawatt eneriziteshi zamandla ze-gy storage, ezinokuvumelana nezimo okuqinile.
I-VRFBinezinga elikhulu lenkululeko ekukhetheni indawo futhi ithatha indawo encane. Isistimu ingavalwa ngokugcwele futhi isebenze ngaphandle kwenkungu ye-asidi nokugqwala kwe-asidi. I-electrolyte ingasetshenziswa kabusha, akukho kukhishwa, ukugcinwa okulula kanye nezindleko eziphansi zokusebenza. Kuwubuchwepheshe bokugcina amandla aluhlaza. Ngakho-ke, ekukhiqizeni amandla avuselelekayo, amabhethri e-vanadium ayizindawo ezikahle zamabhethri e-lead-acid.
Ibhethri ye-Vanadiumizici impilo yesistimu ende. Ukusebenza kahle kwesistimu kuphezulu. Ukusebenza kahle komjikelezo wesistimu yebhethri ye-vanadium kungafinyelela ku-65-80%. Sekela ukushaja nokukhishwa njalo. Amabhethri e-Vanadium asekela ukushajwa nokushajwa kwamanje okuphezulu, futhi angashajwa futhi ashajwe izikhathi ezingamakhulu ngosuku ngaphandle kokunciphisa umthamo webhethri. Isekela ukukhokhiswa ngokweqile nokukhipha ngokweqile. Isistimu yebhethri ye-vanadium isekela ukushaja okujulile nokukhipha (DOD 80%) ngaphandle kokulimaza ibhethri. Isilinganiso sokushaja nokukhishwa ngu-1.5:1. Isistimu yebhethri ye-vanadium ingakwazi ukushaja ngokushesha futhi ikhiphe ukuze ihlangabezane nezidingo zomthwalo. Izinga lokuzikhulula eliphansi. Izinto ezisebenzayo kuma-electrolyte aqondile noma angalungileamabhethri e-vanadiumagcinwa emathangeni ahlukene. Kumodi yokuvala shaqa uhlelo, i-electrolyte ethangini ayinayo into yokuzikhipha.
Ukuqalisa kuyashesha. Ngesikhathi sokusebenza kwe-isistimu yebhethri ye-vanadium, isikhathi sokushaja nokukhipha singaphansi kwe-millisecond engu-1/umklamo wesistimu yebhethri uyavumelana nezimo. Amandla nomthamo wesistimu yebhethri ye-vanadium ingaklanywa ngokuzimela futhi icushwe ngokwezidingo zamakhasimende ukuze kuzuzwe ukuthuthukiswa okusheshayo. Izindleko zokunakekela eziphansi. Isistimu yebhethri ye-vanadium ibona ukusebenza okuzenzakalelayo ngokugcwele, izindleko eziphansi zokusebenza, isikhathi eside sokulungiswa kanye nokugcinwa okulula. Inobungani nemvelo futhi ayingcolisi. Isistimu yebhethri ye-vanadium ivaliwe ekamelweni lokushisa futhi ihlangabezana nezidingo zokuvikela imvelo. Ingabuyiselwa ngokuphelele ngaphandle kwezinkinga zokulahla.
