Ukuxuba iibrendi okanye amandla ngokunxuseneyo kudala iingxaki zokuthembeka. Ukuphunyezwa kwe-BMS okwahlukeneyo kusebenzisa imiqobo yombane eyahlukeneyo kunye nemida yangoku. Inkqubo isebenza kwelona lisezantsi idinomineyitha{2}}eyona BMS igcina imida kwibhanki iyonke. Okubaluleke ngakumbi, ukungahambelani kwamandla kubangela ukuguga okungalinganiyo. Imodyuli ye-5 kWh edityaniswe nemodyuli ye-10 kWh ifumana amava aphindwe kabini umjikelo wokubala kwamandla afanayo, ithotywa ngokukhawuleza kuneqabane layo elikhulu. Namathela kwiimodyuli ezifanayo ezivela kumenzi ofanayo kunye nemihla yokuvelisa efanayo.
Luluphi uhambo oluya{0}}lokujikeleza olufanelekileyo endimele ndilulindele kwiimeko zokwenyani zelizwe-?
Iibhetri ze-LFP zifezekisa u-90-93% wokujikeleza{2}}uhambo olusebenzayo ngokufanelekileyo{4}}kwizicelo zokuhlala zehlabathi. Ukusebenza kuyahluka ngentlawulo{5}}yesantya sokukhupha{19}}intlawulo ekhawulezayo kunye nokukhupha kunciphisa ukusebenza kakuhle. Ngezinga le-1C (ukutshaja ngokupheleleyo okanye ukukhupha ngeyure enye), lindela i-90-92% ukusebenza kakuhle. Kwizinga le-0.5C (i-2-iyure intlawulo okanye ukukhutshwa), ukusebenza kakuhle kuphucula kwi-92-93%. Kwizinga le-0.2C (i-5-iyure intlawulo okanye ukukhutshwa), ukusebenza kakuhle kufikelela kwi-93-94%. Oku kudlula iibhetri ze-lead-acid, ezifikelela kuphela i-75-80% yokusebenza kakuhle kokujikeleza.
Kubaluleke kangakanani-ukuzifudumeza kwimozulu ebandayo?
Ukuzifudumeza-kuba yimfuneko ngaphantsi kwe-5℃ukugcina ukusebenza kunye nokuthintela umonakalo wokutshaja. Ngaphandle kokuzifudumeza-, umthamo okhoyo wehla nge-20-}30% kumaqondo omkhenkce. Okubaluleke ngakumbi, ukutshaja iiseli ezikhenkcezisiweyo kubeka emngciphekweni umonakalo osisigxina we-lithium plating. Ukuzifudumeza{10}kongeza iindleko zangaphambili kodwa kungqina ukuba kuyimfuneko kwimozulu efumana amaqondo obushushu ebusika angaphantsi kwengqele. Ukuba uhlala apho amaqondo obushushu ehla rhoqo ngaphantsi kwe-5℃, phatha ukuzifudumeza njengento enyanzelekileyo kunokuzikhethela.
Ukwenza iSigqibo sokuSebenza
Ukusebenza kuvela ekudibaneni komgangatho weseli, ulawulo lobushushu, ubugocigoci be-BMS, kunye nokudityaniswa kwenkqubo efanelekileyo{0}}hayi kwigama lophawu lodwa.
Qala ngobunyani bakho bemozulu. Ufakelo lwasePhoenix ludinga ubunzima be-thermal kunye nokungena komoya ngaphezu kokuzifudumeza{1}. Iinkqubo zaseMinnesota zifuna ukubanda ngamandla{3}}kwimozulu. Ufakelo lwaseCalifornia elunxwemeni lunokusebenzisa ulawulo olulula lwe-thermal.
Tshatisa ubomi obulindelweyo bomjikelo kwipatheni yakho yosetyenziso. Ukuhamba ngebhayisikile yemihla ngemihla ye-arbitrage yelanga okanye iimfuno zamandla ezigciniweyo 6,{2}} iinkqubo zomjikelo. Ngamaxesha athile ugcino{4}}usebenzisa kuphela imisebenzi ngokwaneleyo nge-3,000-4,000 yeesistim zomjikelo-awusoze usondele kubalo lomjikelo ophezulu.
Qwalasela ulwandiso lwakho lwexesha. Ukuqala nge-10 kWh kodwa uceba ukwandisa ukuya kuma-30 kWh kwisithuba seminyaka emibini kuxoxwa ngeenkqubo ezixhasa amanani aphezulu anxuseneyo ngaphandle kokuthotywa kokusebenza. Kungenjalo, ukukhetha umthamo ophakamileyo wangaphambili uthintela ukuxuba iivintages kunye neentloko ezihambelanayo ezinokubakho.
Inyani yohlahlo lwabiwo-mali imisela ukuba iinkqubo zeprimiyamu zithethelela iindleko zazo. I-Pytes iyalela malunga ne-20-30% yeprimiyamu yexabiso ngaphezulu kweEG4. Loo premium ithenga amaxabiso asezantsi enkathazo yokuvala iBMS kunye nobomi bomjikelo omde kancinane. Kusetyenziso olubalulekileyo (ugcino lwezixhobo zonyango, ngaphandle{6}}umbane ongundoqo wegrid), iprimiyamu iyazithethelela. Kwigridi{7}}ebotshelelwe kwi-arbitrage yelanga apho ukuvalwa ngamathuba athile kunciphisa nje ukonga ngaphandle kokubangela ukungabikho, iinkqubo ezijolise kwixabiso zanele.
Elona -elisebenzayo lokugcina amandla LFP epakishwe ibhetri ipakethi ixhomekeke ngokupheleleyo kwiimfuno zakho zesicelo, iimeko zemozulu, kunye neeparamitha zohlahlo lwabiwo-mali kunobunganga bohlobo jikelele.
