dongosolo la batri la vanadium (VRFB VRB)

Monga malo omwe zimachitika,mulu wa vanadiumimalekanitsidwa ndi thanki yosungiramo electrolyte, yomwe imagonjetsa vuto lodzitulutsa lokha la mabatire achikhalidwe. Mphamvu imangodalira kukula kwa mulu, ndipo mphamvu imangodalira kusungira ndi kukhudzika kwa electrolyte. Kapangidwe kake ndi kosinthasintha kwambiri; pamene mphamvuyo ndi yosasintha, kuti muwonjezere mphamvu yosungiramo mphamvu, ndikofunikira kuwonjezera kuchuluka kwa thanki yosungiramo electrolyte kapena kuwonjezera kuchuluka kwa electrolyte. Inde, popanda kusintha kukula kwa mulu; cholinga cha "kuchaja mwachangu" chingapezeke mwa kusintha kapena kuwonjezera electrolyte mu mkhalidwe wa chaji. Ingagwiritsidwe ntchito kupanga kilowatt-level kufika pa 100-megawatt enermalo osungira magetsi a gy, okhala ndi mphamvu zosinthasintha.

VRFBIli ndi ufulu waukulu posankha malo ndipo imatenga malo ochepa. Dongosololi likhoza kutsekedwa kwathunthu ndikuyendetsedwa popanda asidi ndi dzimbiri la asidi. Electrolyte ikhoza kugwiritsidwanso ntchito, palibe mpweya woipa, kukonza kosavuta komanso ndalama zochepa zogwirira ntchito. Ndi ukadaulo wosungira mphamvu zobiriwira. Chifukwa chake, popanga mphamvu zongowonjezwdwanso, mabatire a vanadium ndi njira yabwino kwambiri yolowa m'malo mwa mabatire a lead-acid.

Batri ya VanadiumIli ndi moyo wautali wa dongosolo. Kugwira ntchito bwino kwa dongosolo ndi kwakukulu. Kugwira ntchito bwino kwa dongosolo la batri ya vanadium kumatha kufika 65-80%. Kuthandizira kuyitanitsa ndi kutulutsa nthawi zonse. Mabatire a Vanadium amathandizira kuyitanitsa ndi kutulutsa nthawi zambiri, ndipo amatha kuyitanitsa ndi kutulutsa nthawi zambiri patsiku popanda kuchepetsa mphamvu ya batri. Imathandizira kuyitanitsa ndi kutulutsa nthawi zambiri. Dongosolo la batri ya vanadium limathandizira kuyitanitsa ndi kutulutsa nthawi yayitali (DOD 80%) popanda kuwononga batri. Chiŵerengero cha kuyitanitsa ndi kutulutsa nthawi ndi 1.5:1. Dongosolo la batri ya vanadium limatha kuyitanitsa ndi kutulutsa nthawi mwachangu kuti likwaniritse zofunikira zonyamula. Kuthamanga kochepa kodzitulutsa. Zipangizo zogwira ntchito mu ma electrolyte abwino ndi oipa amabatire a vanadiumzimasungidwa m'matangi osiyana. Mu njira yozimitsa dongosolo, electrolyte yomwe ili mu tangiyo siili ndi vuto lodzitulutsa yokha.

Kuyambitsa kumachitika mwachangu. Pa nthawi yogwira ntchitodongosolo la batri la vanadium, nthawi yochaja ndi kutulutsa ndi yochepera 1 millisecond/kapangidwe ka batire ndi kosinthasintha. Mphamvu ndi mphamvu ya batire ya vanadium zitha kupangidwa ndi kukonzedwa payokha malinga ndi zosowa za makasitomala kuti zikwaniritse zosintha mwachangu. Mtengo wotsika wokonza. Batire ya vanadium imagwira ntchito yokha, mtengo wotsika wogwirira ntchito, nthawi yayitali yokonza komanso kukonza kosavuta. Ndi yoyera komanso yopanda kuipitsa. Batire ya vanadium imatsekedwa kutentha kwa chipinda ndipo imakwaniritsa zofunikira zoteteza chilengedwe. Itha kubwezeretsedwa kwathunthu popanda vuto lililonse lotaya.
