Iinkqubo zisusela kwiiyunithi ezingama-300 zekWh kuncedo oluncinci lwentengiso ukuya kwi-8 MWh kuqwalaselo ukwenzela izinto eziluncedo{7}}iiprojekthi zesikali, ezineendleko phakathi kwe-$400-800 nge-kWh nganye ngokuxhomekeke kwiinkcukacha kunye nenqanaba lokudibanisa.
Ukuqonda IiMfuno zesiGaba seNkqubo
Ukuthelekisa ubungakanani besikhongozeli nemfuno yamandla kuqala ngokubala iimfuno zakho zokwenyani kunokuthenga ngokusekelwe kwintelekelelo. Imakethi egciniweyo yogcino lwamandla ifikelele kwi-9.33 yeebhiliyoni zeedola ngo-2024 kwaye iyaqhubeka nokukhula nge-20.9% ngonyaka, kodwa ukuthunyelwa okuninzi kuyasilela ngenxa yobungakanani obungafanelekanga.
Umthamo wamandla ugqiba ukuba ungakanani umbane owugcinayo kwisistim yakho, ulinganiswa ngeekilowatt-iiyure (kWh) okanye iimegawathi-iiyure (MWh). Inkqubo ye-1 MWh igcina amandla awoneleyo ukunika amandla malunga nama-300 amakhaya aphakathi kwiyure enye. Umlinganiselo wamandla, olinganiswa ngeekilowathi (kW) okanye iimegawathi (MW), ubonisa ukuba loo mandla anokukhutshwa ngokukhawuleza kangakanani na.
Izikhongozeli eziMgangatho ezingama-20indlu 300 kWh ukuya 1 MWh umthamo wokugcina. Olu lungelelwaniso lwenkqubo yogcino lwamandla oluqulathiweyo lulungele imisebenzi yorhwebo emincinci ukuya kwephakathi, izikhululo zokutshaja ze-EV, kunye neeprojekthi ezisasazwayo ezihlaziyiweyo. Iiyunithi zangoku ezingama-20ft zifezekisa uxinaniso lwamandla angama-541 kWh/m² ekusikeni{6}}kuyilo olusecaleni olufana nenkqubo ye-Envision's 8 MWh eyasungulwa ngoSeptemba ka-2024. Nangona kunjalo, uninzi losasazo lwezorhwebo lusebenzisa ubumbeko lwe-500-750 kWh kunye neenkqubo zokuguqula amandla angama-250-300 kW.
Izikhongozeli zeenyawo ezingama-40ithathe indawo eyi-1-3.5 MWh, inceda amaziko amakhulu emizi-mveliso, izitishi eziluncedo, kunye neefama ezivuselelekayo zegridi. Ubude obongezelelweyo buvumela iiracks ezininzi zebhetri kunye neenkqubo zolawulo oluphuculweyo lwe-thermal. Inkqubo ye-CATL ye-Tianheng ipakisha i-6.25 MWh kwisikhongozeli esiqhelekileyo se-40ft, inyusa uxinano lwamandla kwindawo nganye yeyunithi ngama-30% xa kuthelekiswa neemodeli zika-2023.
