Kwimiba yanamhlanje yeenkqubo zamandla, ukugcinwa kwamandla kumi njengento ebalulekileyo eqinisekisa ukuhlanganiswa okungenamthungo kwemithombo yamandla avuselelekayo kunye nokuqinisa uzinzo lwegridi. Usetyenziso lwayo lubandakanya ukuveliswa kombane, ulawulo lwegridi, kunye nokusetyenziswa komsebenzisi wokugqibela, okwenza kube yiteknoloji engabalulekanga. Eli nqaku lijonge ukuvavanya nokuphonononga uhlalutyo lweendleko, imeko yophuhliso lwangoku, kunye namathuba exesha elizayo eenkqubo zokugcina amandla ebhetri ye-lithium-ion.
Uhlalutyo lweendleko zeNkqubo zokugcina amandla:
Ulwakhiwo lweendleko zeenkqubo zokugcina amandla luquka ikakhulu izinto ezintlanu: iimodyuli zebhetri, iiNkqubo zoLawulo lweBhetri (i-BMS), izikhongozeli (eziquka iiNkqubo zoGuqulo lwaMandla), iindleko zokwakha nokufakela, kunye nezinye iindleko zoyilo kunye nokulungisa iingxaki. Ukuthatha umzekelo wenkqubo yokugcina amandla ye-3MW/6.88MWh evela kumzi-mveliso kwiPhondo laseZhejiang, iimodyuli zebhetri zenza i-55% yeendleko zizonke.
Uhlalutyo oluthelekisayo lweeTekhnoloji zeBhetri:
Inkqubo yokugcina amandla ye-lithium-ion iquka ababoneleli bezixhobo eziphezulu, abahlanganisi be-midstream, kunye nabasebenzisi bokugqibela abasezantsi. Izixhobo ziqala kwiibhetri, iiNkqubo zoLawulo lwaMandla (EMS), iiNkqubo zoLawulo lweBhetri (BMS), ukuya kwiiNkqubo zoGuqulo lwaMandla (PCS). Abahlanganisi baquka abahlanganisi beenkqubo zokugcina amandla kunye neefemu zobuNjineli, ukuThenga, kunye noKwakha (EPC). Abasebenzisi bokugqibela baquka ukuveliswa kombane, ulawulo lwegridi, ukusetyenziswa komsebenzisi wokugqibela, kunye namaziko onxibelelwano/wedatha.
Ukwakhiwa kweendleko zebhetri yeLithium-ion:
Iibhetri zeLithium-ion zisebenza njengezona zinto ziphambili kwiinkqubo zokugcina amandla e-electrochemical. Okwangoku, imakethi inika ubuchwepheshe obahlukeneyo beebhetri ezifana ne-lithium-ion, i-lead-carbon, iibhetri zokuhamba, kunye neebhetri ze-sodium-ion, nganye inamaxesha okuphendula ahlukeneyo, ukusebenza kakuhle kokukhupha, kunye neenzuzo kunye neengxaki ezilungiselelwe wena.
Iindleko zeebhetri zenza isabelo esikhulu seendleko zenkqubo yokugcina amandla e-electrochemical, ezifikelela kwi-67%. Iindleko ezongezelelweyo ziquka ii-inverters zokugcina amandla (10%), iinkqubo zolawulo lwebhetri (9%), kunye neenkqubo zolawulo lwamandla (2%). Ngaphakathi kweendleko zebhetri ye-lithium-ion, izinto ze-cathode zibanga inxalenye enkulu malunga ne-40%, zilandelwa zizinto ze-anode (19%), i-electrolyte (11%), kunye ne-separator (8%).
Iindlela Ezisetyenziswayo Neengxaki Zangoku:
Ixabiso leebhetri zokugcina amandla liye labonakala lihla ngenxa yokwehla kwamaxabiso e-lithium carbonate ukusukela ngo-2023. Ukwamkelwa kweebhetri ze-lithium iron phosphate kwimarike yokugcina amandla yasekhaya kuye kwakhuthaza ngakumbi ukwehla kweendleko. Izinto ezahlukeneyo ezifana nezixhobo ze-cathode kunye ne-anode, i-separator, i-electrolyte, i-current collector, izinto zokwakha, kunye nezinye ziye zabona utshintsho lwamaxabiso ngenxa yezi zinto.
Nangona kunjalo, imakethi yeebhetri zokugcina umbane itshintshile ukusuka ekunqongophaleni kwamandla ukuya kwimeko yokubonelela ngokugqithisileyo, nto leyo eqinisa ukhuphiswano. Abangeneleli abavela kumacandelo ahlukeneyo, kuquka abavelisi beebhetri zamandla, iinkampani ze-photovoltaic, iinkampani ezisakhulayo zokugcina umbane, kunye namaqhawe asele ekhulile kushishino, bangene kule mbambano. Olu qhankqalazo, kunye nokwandiswa kwamandla abadlali abakhoyo, lubeka umngcipheko wokulungiswa kwakhona kwemarike.
Isiphelo:
Nangona kukho imingeni ekhoyo yokubonelela ngokugqithisileyo kunye nokhuphiswano oluphezulu, imakethi yokugcina amandla iyaqhubeka nokukhula kwayo ngokukhawuleza. Ithathwa njengendawo enokuba yitriliyoni zeedola, inika amathuba okukhula okukhulu, ingakumbi phakathi kokukhuthazwa okuqhubekayo kwemigaqo-nkqubo yamandla avuselelekayo kunye namacandelo ezoshishino kunye norhwebo aseTshayina akhutheleyo. Nangona kunjalo, kweli nqanaba lokubonelela ngokugqithisileyo kunye nokhuphiswano oluncinci, abathengi abasezantsi baya kufuna imigangatho yomgangatho ophezulu yeebhetri zokugcina amandla. Abatsha kufuneka babeke imiqobo yetekhnoloji kwaye bahlakulele ubuchule obuphambili ukuze bachume kule ndawo iguqukayo.
Ngokufutshane, imakethi yaseTshayina yeebhetri ze-lithium-ion kunye nokugcinwa kwamandla inika imingeni emininzi kunye namathuba. Ukuqonda uhlalutyo lweendleko, iindlela zobuchwepheshe, kunye nokuguquguquka kwemarike kubalulekile kumashishini azama ukwenza ubukho obumangalisayo kweli shishini litshintsha ngokukhawuleza.
