Iibhetri ze-EV Lithium zineeMfuno zokuSebenza eziMiselweyo ngakumbi
Ngenxa yokunciphisa ubungakanani kunye nobunzima bemoto kunye neemfuno zokuqalisa ukukhawuleza, iibhetri ze-EV zineemfuno eziphezulu zokusebenza kuneebhetri eziqhelekileyo zokugcina amandla.Umzekelo, ubuninzi bamandla kufuneka bube phezulu kangangoko kunokwenzeka, isantya sokutshaja kwebhetri kufuneka sikhawuleze, kwaye ukukhutshwa kwangoku kufuneka kube kukhulu.Iimfuno zeebhetri zokugcina amandla aziphezulu kakhulu.Ngokwemigangatho, iibhetri ze-EV ezinomthamo ongaphantsi kwe-80% azinakuphinda zisetyenziswe kwizithuthi zamandla amatsha, kodwa zingasetyenziselwa kwiinkqubo zokugcina amandla ngokuguqulwa okuncinci.
Umahluko kwiMiyeko yeSicelo
Ngokwembono yeemeko zesicelo, iibhetri ze-EV lithium zisetyenziswa ikakhulu kwizithuthi zombane, iibhayisekile zombane kunye nezinye izixhobo zamandla, ngelixa iibhetri ze-lithium zokugcina amandla zisetyenziswa kakhulu kwiinkonzo zokuncedisa amandla ombane, igridi yamandla avuselelekayo kunye negridi encinci. amasimi.
Iibhetri ze-EV Lithium zezoNxinano lwaMandla oPhezulu
Ngenxa yeemeko ezahlukeneyo zosetyenziso, iimfuno zokusebenza kwebhetri nazo zahlukile.Okokuqala, njengomthombo wamandla ohambahambayo, ibhetri ye-lithium ye-EV ineemfuno eziphezulu kangangoko kunokwenzeka kumthamo (kunye nobunzima) amandla obuninzi phantsi kwesiseko sokhuseleko, ukuze kufezekiswe ukunyamezela ixesha elide.Ngexesha elifanayo, abasebenzisi banethemba lokuba izithuthi zombane zinokukhuseleka kwaye zihlawuliswe ngokukhawuleza.Ke ngoko, iibhetri ze-lithium ze-EV zineemfuno eziphezulu zokuxinana kwamandla kunye nokuxinana kwamandla.Kungenxa nje yengqwalasela yokhuseleko ukuba iibhetri zohlobo lwamandla ezinentlawulo kunye nomthamo wokukhupha malunga ne-1C zisetyenziswa ngokubanzi.
Uninzi lwezixhobo zokugcina amandla zimile, ngoko ke iibhetri ze-lithium zokugcina amandla azikho iimfuno ezithe ngqo zokuxinana kwamandla.Ngokuphathelele ubuninzi bamandla, iimeko ezahlukeneyo zokugcina amandla zineemfuno ezahlukeneyo.
Ngokuqhelekileyo, ibhetri yokugcina amandla kufuneka ihlawulwe ngokuqhubekayo okanye ikhutshwe ngokuqhubekayo ngaphezu kweeyure ezimbini zokucheba i-peak yamandla, i-off-grid photovoltaic energy storage, okanye iimeko zokugcina amandla e-peak-to-valley kwicala lomsebenzisi.Ngoko kulungele ukusebenzisa uhlobo lomthamo kunye nexabiso lokukhupha intlawulo ≤0.5C ibhetri;Kwiimeko zokugcina amandla apho ukumodareyithwa kwamandla ombane okanye ukuguquguquka kwamandla ahlaziyekayo kufuneka, ibhetri yokugcina amandla kufuneka ihlawulwe ngokukhawuleza kwaye ikhutshwe kwixesha lesibini ukuya kwimizuzu, ngoko ifanelekile kwizicelo ezineebhetri zamandla ≥2C;kwaye kwezinye iimeko, kufuneka yenze ukumodareyitha rhoqo Kwiimeko zokusetyenziswa kokutsheva okuphezulu, iibhetri zohlobo lwamandla zifanelekile ngakumbi.Ngokuqinisekileyo, uhlobo lwamandla kunye nohlobo lwebhetri lunokusetyenziswa kunye kule meko.
Ibhetri yoGcino lwaMandla inoBomi obude beNkonzo
Xa kuthelekiswa neebhetri ze-lithium zamandla, iibhetri ze-lithium zokugcina amandla zineemfuno eziphezulu zobomi benkonzo.Ubomi bezithuthi zamandla amatsha ngokubanzi yiminyaka emi-5-8, ngelixa ubomi beeprojekthi zokugcina amandla ngokuqhelekileyo kulindeleke ukuba bube bukhulu kuneminyaka eyi-10.Ubomi bomjikelezo webhetri ye-lithium yamandla ngamaxesha angama-1000-2000, kwaye ubomi bomjikelezo wokugcinwa kwamandla ebhetri ye-lithium ngokuqhelekileyo bufuneka ukuba bube bukhulu kunamaxesha angama-5000.
Iindleko zeBhetri yokuGcina amandla ziPhantsi
Ngokweendleko, iibhetri ze-EV zijongene nokhuphiswano kunye nemithombo yamandla emveli, ngelixa iibhetri ze-lithium zokugcina amandla kufuneka zijongane nokhuphiswano lweendleko ukusuka kwincopho yemveli kunye nobuchwepheshe bomodulation frequency.Ukongeza, isikali sezikhululo zamandla okugcina amandla ngokusisiseko singaphezulu komgangatho wemegawathi okanye neemegawathi ezili-100.Ngoko ke, iindleko zokugcina amandla iibhetri ze-lithium ziphantsi kuneebhetri ze-lithium zamandla, kwaye iimfuno zokhuseleko nazo ziphezulu.
Kukho ezinye iiyantlukwano phakathi kweebhetri ze-lithium ze-EV kunye nokugcinwa kwamandla e-lithium iibhetri, kodwa ukusuka kwindawo yokujonga iiseli, ziyafana.Zombini iibhetri ze-lithium iron phosphate kunye neebhetri ze-ternary lithium zingasetyenziswa.Umahluko omkhulu ulele kwinkqubo yokulawula ibhetri yeBMS kunye nesantya sokuphendula amandla ebhetri.Kwaye iimpawu zamandla, ukuchaneka koqikelelo lwe-SOC, ukuhlawuliswa kunye neempawu zokukhupha, njl., zonke zinokuphunyezwa kwi-BMS.
