vanadium batire system (VRFB VRB)

Monga malo zomwe zimachitika, ndichikwama cha vanadiumimasiyanitsidwa ndi thanki yosungiramo ma electrolyte, yomwe imagonjetsa kudziletsa kwa mabatire achikhalidwe. Mphamvu zimangotengera kukula kwa stack, ndipo mphamvu zimangotengera kusungirako kwa electrolyte ndi ndende. Mapangidwewo ndi osinthika kwambiri; mphamvu ikakhala yokhazikika, kuwonjezera mphamvu yosungiramo mphamvu, ndikofunikira kuwonjezera kuchuluka kwa tanki yosungira ma electrolyte kapena kuwonjezera voliyumu kapena kuchuluka kwa electrolyte. Inde, popanda kusintha kukula kwa stack; cholinga cha "kulipira pompopompo" chikhoza kukwaniritsidwa mwa kusintha kapena kuwonjezera ma electrolyte m'malo olipira. Itha kugwiritsidwa ntchito pomanga kilowatt-level mpaka 100-megawatt enermalo opangira magetsi a gy, okhala ndi mphamvu zosinthika.

Chithunzi cha VRFBali ndi ufulu wambiri pakusankha malo ndipo amakhala ndi malo ochepa. Dongosololi limatha kutsekedwa kwathunthu ndikuyendetsedwa popanda nkhungu ya asidi ndi dzimbiri la asidi. Electrolyte ikhoza kugwiritsidwanso ntchito, osatulutsa mpweya, kukonza kosavuta komanso kutsika mtengo kogwiritsa ntchito. Ndiukadaulo wobiriwira wosungira mphamvu. Chifukwa chake, pakupangira mphamvu zongowonjezwdwanso, mabatire a vanadium ndi abwino m'malo mwa mabatire a lead-acid.

Battery ya Vanadiumzimaonetsa moyo wautali wadongosolo. Dongosolo bwino kwambiri. Kuchita bwino kwa batire ya vanadium kumatha kufika 65-80%. Thandizani kulipira pafupipafupi ndi kutulutsa. Mabatire a Vanadium amathandizira kuyitanitsa ndi kutulutsa pafupipafupi, ndipo amatha kulipiritsa ndikutulutsidwa kambirimbiri patsiku popanda kuchepetsa mphamvu ya batri. Imathandizira kuchulukirachulukira komanso kutulutsa. Dongosolo la batri la vanadium limathandizira kutulutsa kwakuya ndi kutulutsa (DOD 80%) popanda kuwononga batire. Chiyerekezo cha kutulutsa ndi 1.5: 1. Dongosolo la batri la vanadium limatha kuzindikira kuyitanitsa mwachangu ndikutulutsa kuti likwaniritse zofunikira. Kutsika kwamadzimadzimadzimadzi. The yogwira zipangizo mu zabwino ndi zoipa electrolytes wavanadium mabatireamasungidwa mu akasinja osiyana. Mu dongosolo shutdown mode, electrolyte mu thanki alibe kudziletsa kumaliseche chodabwitsa.

Kuyambitsa ndikofulumira. Pa nthawi ya ntchito yavanadium batire dongosolo, nthawi yolipiritsa ndi kutulutsa ndi yochepera 1 millisecond/kapangidwe kake ka batri kamakhala kosavuta. Mphamvu ndi mphamvu ya makina a batri a vanadium amatha kupangidwa paokha ndikukonzedwa malinga ndi zomwe makasitomala amafuna kuti akwaniritse kukweza mwachangu. Mtengo wochepa wokonza. Dongosolo la batri la vanadium limazindikira magwiridwe antchito, mtengo wotsika, nthawi yayitali yokonza komanso kukonza kosavuta. Osamawononga chilengedwe komanso alibe kuipitsa. Dongosolo la batire la vanadium limatsekedwa kutentha komanso limakwaniritsa zofunikira zoteteza chilengedwe. Ikhoza kubwezeretsedwanso popanda zovuta zilizonse.
