Lub graphite bipolar phaj rau cov kua ntws roj teeb ua ke nrog photovoltaic / cua zog yog ib qho tseem ceeb ntawm cov khoom tsim los ua kom tau raws li cov yam ntxwv ntawm lub zog hluav taws xob tshiab thiab tsim nyog rau lub sijhawm ntev - lub zog cia. Nws yog tsim tshwj xeeb los daws peb qhov teeb meem loj ntawm kev sib cuam tshuam, tsis muaj zog, thiab tsis muaj kev cia siab ntawm photovoltaic / cua zog. Nws koom ua ke plaub lub luag haujlwm: kev sib kis tam sim no, kev faib hluav taws xob, kev txhawb nqa cov qauv, thiab kev sib khi sib cais. Nws ua haujlwm raws li "zog hluav taws xob" txuas lub photovoltaic / cua fais fab inverter thiab cov roj teeb ua kua roj teeb, ncaj qha txiav txim siab lub zog hloov dua siab tshiab, cov lus teb ceev, lub neej voj voog, thiab tus nqi ib kilowatt-teev ntawm kev sib xyaw ua ke.
Cov phaj bipolar no tsuas yog tsim nyog rau cov khoom siv hluav taws xob hauv cov roj ntsha xws li vanadium, hlau -chromium, thiab zinc- bromine. Nws tuaj yeem ua haujlwm ruaj khov nyob rau hauv siab - zaus them thiab tso tawm cov xwm txheej (3-5 zaug hauv ib hnub), kev hloov pauv ntawm lub zog dav (0-100% ntawm lub zog ntsuas), thiab qhov kub thiab txias (-20℃txog 50℃). Nws ua tau raws li peb qhov yuav tsum tau ua ntawm cov khoom lag luam du rau photovoltaic thiab cua fais fab, kev tswj xyuas qhov siab tshaj plaws thiab lub kwj deg filling, thiab lub zog thaub qab.
