Izithintelo zemithombo azibopheleli kangako kunoko kukholelwa ngokuqhelekileyo kwaye ziyaqhubeka nokukhulula njengoko ukubonelela ngekhonkco lukhula. Itekhnoloji isebenza njengoko ipapashiwe xa isetyenziswe ngokuchanekileyo.
Kubaqhubi begridi, ukugcinwa kwebhetri kutshintshile ukusuka kwisithembiso sexesha elizayo ukuya kwimfuneko yangoku. Utshintsho lwamandla luyalufuna, uqoqosho luyaluthanda, kwaye unyaka nonyaka ukulibaziseka kuthetha ukonga kwangaphambili kunye nokuphuculwa kokuthembeka.
Imibuzo ebuzwa qho
Ingaba igridi{0}}izistim zebhetri zihlala ixesha elingakanani?
Iibhetri ze-lithium iron phosphate zikholisa ukuzisa ama-2,000 ukuya kuma-5,000 umjikelo wokukhupha{4}}ngokuxhomekeke kwiipateni zosetyenziso kunye nolawulo. Kumjikelo omnye ngosuku, oku kuguqulela kwiminyaka emi-5-15 yobomi bokusebenza ngaphambi kokuba umthamo wehliswe ngaphantsi kwe-80%. Iisistim ezininzi zibandakanya izibonelelo zokutshintsha iimodyuli zebhetri ngelixa ugcina ulungelelwaniso lwesixokelelwano, ukwandisa ubomi boncedo ukuya ku-20+ iminyaka ngophuculo lwamaxesha ngamaxesha.
Kwenzeka ntoni xa ugcino lwebhetri luvutha umlilo?
Iinkqubo zanamhlanje zibandakanya iileya ezininzi zokhuseleko. Iinkqubo zolawulo lwe-thermal zithintela ukushisa ngaphambi kokuba kufikelele kumanqanaba ayingozi. Ukuba ukubaleka kwe-thermal kuqala kwimodyuli enye, iinkqubo zokunciphisa umlilo zisebenza ngelixa izithintelo zomzimba ziqulethe ukusabalalisa. Umzi-mveliso ufundwe kwizehlo zakuqala -zoqhushumbo lwase-Arizona ngo-2019 olonzakalisa abacimi-mlilo abasibhozo kunye nogqabhuko-dubulo lwaseBeijing ngo-2021 olubulale abacimi-mlilo ababini lukhokelele kuhlaziyo lweprotocol yokhuseleko. Izenzo ezilungileyo zangoku zibandakanya umoya ophuculweyo, iinkqubo zokufumanisa eziphuculweyo, kunye noqeqesho lwabacimi-mlilo olukhethekileyo kwiindawo zokugcina iibhetri.
Ngaba iibhetri ziyayiphelisa ngokwenene imfuneko yezityalo ezikwincopho yegesi?
Ngexesha elifutshane-incopho, ewe. Izityalo ezikwincopho yerhasi zijongene noxinzelelo lwezoqoqosho olusuka kwiibhetri zokugcina amandla egridi, ezinezixokelelwano ze-lithium-esele zikhuphisana ngokwezoqoqosho ngeenkonzo ezihamba phambili kwiimarike ezifana neCalifornia. Nangona kunjalo, iibhetri okwangoku ziyasokola ngeziganeko zobude obude-ezininzi{5} zeentsuku zokuzola okanye amaza obushushu. Igridi ekhutshwe ngokupheleleyo inokuba ifuna iibhetri kangangeeyure{7}}iincopho zobude kunye nezinye izisombululo ({8}}ukugcinwa kwexesha elide, ukuveliswa okuqinileyo okucocekileyo, okanye ukubanga ubhetyebhetye) kwiziganeko ezinde.
Ingaba iibhetri{0} zobomi besibini ze-EV zithelekiseka njani neebhetri ezintsha zogcino lwegridi?
Iindleko yeyona nzuzo iphambili-30-50% ephantsi kwisiseko esifakwe ngokupheleleyo. Ukwahluka kwentsebenzo kuxhomekeke kwimeko yokuqala yebhetri kunye neemfuno zesicelo. Ugcino lwegridi lubandakanya ukukhwela ibhayisekile kunokusebenzisa iimoto, ukwenza iibhetri ze-EV ezonakeleyo zifaneleke nangona umthamo uncitshisiwe. Imingeni ephambili yi-heterogeneity (abavelisi abahlukeneyo kunye neekhemistri), iindleko zokuvavanya, kunye nezakhiwo zewaranti. Omnye umhlalutyi waqaphela ukuba ukuba iibhetri ze-EV zihlala iminyaka eyi-20+ ezimotweni, izixa ezibalulekileyo aziyi kufumaneka ukuba ziphinde zisetyenziswe de kube semva kuka-2040.
