Thelekisa iibhetri ezahlukeneyo ezixhasayo kuGcino lwaMandla oSapho
Yeyiphi ibhetri yokugcina amandla ekhaya?
Iimoto zombane ezicocekileyo ziqhutywa ngamandla ombane. Ngokumalunga nomlinganiselo, baphinde bathembele ekwandisweni kweebhetri ze-lithium ngokwemiqathango yokugcina amandla. Ngokukodwa, kukho uthelekiso phakathi kwezi zimbini ngokubhekiselele kuqoqosho ngokubanzi kunye nexesha lokuphila.
1) Uhlalutyo lwemeko yovavanyo lobomi bebhetri yokugcina amandla
Olu luhlu lweemvavanyo e-Australia, kubandakanywa uphando oluphambili malunga nokutshintshwa kweebhetri ze-lithium kunye neebhetri ze-lead-acid. Iye yahlala ixesha elide. Le datha ikwasinceda ukuba siqonde inkqubo yeekhemikhali efanayo kwizicelo ezifanayo. Ukubola kobomi
Iziko lovavanyo lwebhetri lenziwe iSustainableSkillsTrainingHubattheCanberraInstituteof Technology kunye novavanyo lokusebenza sele luqalile.Ngokufutshane oku kubandakanya:UkuBhayisela iibhetri kathathu ngeentsuku ukuya kwiminyaka emithathuukulinganisa iminyaka elithoba’yexabiso’yesiqhelo’ibhayisekile yemihla ngemihla yokunyuka kwebhetri’
Ukulinganisa iimeko zehlabathi lokwenyani ngokwenza ibhayisekile ubushushu bendawo apho iibhetri ziya kufakwa; kwaye,
Uthathela ingqalelo ezi ngqwalasela zimbini zingasentla, imijikelo emithathu ngosuku, kunye nokutshintsha kobushushu bongeziweyo, kushushu ehlotyeni 2 kubanda 1, kubanda ebusika 2 kushushu 1, kwaye ubushushu bukhethwa kwi-10-35degC
Upapasho lwedatha yokusebenza, kubandakanywa neebhetri’ehlisa amandla okugcina kwisithuba seminyaka emithathu yovavanyo
Nazi iibhetri zokugcina amandla zikaTesla endinomdla kuzo, kunye neebhetri ze-NCM ze-LG kunye ne-Samsung (inqanaba lokuqala lokuvavanya)
Amagqabantshintshi: Ugcino lwamandla lweSamsung ngokusisiseko luyafana neebhetri zemoto. Ngenxa yeemfuno zokugcina amandla, kukho ukuqwalaselwa ngakumbi koyilo lobomi bomjikelezo.
Iziphumo zovavanyo lokuqala
1) Ukunciphisa umthamo
2) Iimpawu zokunciphisa inqanaba lokuqala
Ukongeza kokupheliswa kwangoko kwebhetri ye-lithium ye-AVIC, ubomi bomjikelezo webhetri ye-Tesla bubi kakhulu.
Kolu ngcelele lweengxelo, kukho iitafile ezimbini zovavanyo, kubandakanywa inani lemijikelo yobomi, enye ivavanywa kwimijikelo engama-80, enye iya kwimijikelo ye-1400.
Amagqabantshintshi: Enye yezi theyibhile zimbini yindlela yokubala amandla esetyenzisiweyo. Lo mzobo ulandelayo awufani, kodwa unika kuphela uqikelelo lwe-SOH. Kucingelwa ukuba oku kuguqulwa ngokusebenza kakuhle kwegalelo lokuqala kunye namandla aphumayo.
Ukusuka kule tshathi, i-LG kunye ne-SDI zikwi-curve ehambelana nokunciphisa. Kwi-800, i-attenuation imalunga ne-8%.
Idatha kaTesla, amaxesha angama-800 asondele kwi-85%
Iibhetri ze-lead-acid kunye ne-CALB (AVIC’s) azikwazi ukubamba emva kwamaxesha angama-400
Uvavanyo olongezelelweyo
Ngamaxesha e-1100, i-Powerwall kaTesla ingene kuluhlu olungaphantsi kwe-80%
Iibhetri ze-LG zehla ngaphantsi kwe-90% ngamaxesha angama-1,000. Le yinkqubo yebhetri yokugcina amandla kunye noxinano lwamandla aphezulu kuzo zonke.
Iiseli ezinkulu ze-SDI zisajikeleze i-92% emva kwemijikelo ye-1400, elingana ne-sony’s.
Kwinqanaba lesibini lovavanyo, ezinye iimveliso zakhethwa, iTeslaPowerwall2 ehlaziyiweyo yongezwa, kwaye isizukulwana esitsha sokugcina amandla se-LG sahlaziywa.

Iziphumo zovavanyo lwenqanaba lesibini zisaqhubeka, kwaye kuqikelelwa ukuba ngaphezu kwe-1000 amaxesha anokufumaneka ukufumana iziphumo ezicacileyo.
Iibhetri zeZTE zibola ngokukhawuleza, ngcono kancinci kuneSimpliPhi eUnited States
I-Lithium iron phosphate kunye ne-NCM111 iseneziphumo ezifanayo kumjikelezo

2) Uhlalutyo lwezoqoqosho lokugcinwa kwamandla
Ngokukhula okukhawulezayo kwesikali soshishino, ugcino lwamandla ekhemikhali ngoku sesinye setekhnoloji yogcino lwamandla ngokuncipha ngokukhawuleza kweendleko. Iibhetri ze-lithium-ion kunye neebhetri ze-lead-asidi zisetyenziswa njengobuchwepheshe be-benchmark; indlela yegophe yamava isetyenziselwa ukuqikelela ukuhla kweendleko ezahlukeneyo zokugcina amandla Ⅶ, kunye neecurves ezahlukeneyo zamava obugcisa zifunyanwa ngokuhlalutya idatha yembali.
Okwangoku, iindleko zokugcinwa kwempompo ziphantsi kakhulu, kunye neyunithi yokugcina amandla otyalo-mali malunga ne-770 yuan; iindleko zeebhetri ze-lead-acid ziphezulu kancinci, kwi-900 yuan / kWh; iindleko zeebhetri zamandla ombane kunye neebhetri ze-lithium-ion zokugcina amandla ziyafana, kwi-1550-1600 yuan / kWh Ixesha. Nangona kunjalo, ngokwemiqathango yokwehla kweendleko, iindleko zeebhetri zamandla kunye neebhetri ze-lithium-ion zokugcina amandla ziye zawa ngokukhawuleza.
Ukuphawula Umthombo wedatha “Uphononongo malunga neNgcono kunye noQoqosho lweTekhnoloji yokuGcinwa kwaMandla oMbane weSithuthi soMbane”. Uphononongo lusebenzisa uhlalutyo olungagungqiyo lokubuyisela umva ukulungelelanisa ubudlelwane phakathi kwemveliso eyongezelekayo yeebhetri zamandla kunye neendleko zotyalo-mali, kwaye i-equation yokubuyisela ithatha ifom yokusebenza kwamandla17. Ukungaqiniseki koqikelelo lwengqikelelo kubonakaliswa yimposiso eqhelekileyo σ yengqikelelo yengqikelelo, oko kukuthi, i-95% yoluhlu lwexesha lokuzithemba loqikelelo lwesantya soqikelelo yi-1.96 × σ.

Umhla wokuqala woqikelelo lwexabiso lomgangatho wokugcinwa kwamandla ebhetri ngo-2021, kwaye ukwehla kwexabiso layo kubonisa ukwehla okukhawulezayo ekuqaleni, kwaye emva koko ukucotha okubalulekileyo. Inzuzo yeendleko eziphantsi zokuthenga iibhetri eziyekiweyo kwibakala lokuqala kunye nokwehla okucothayo kwixabiso eliphantsi lokusetyenziswa kwenqanaba . Ngokwembono ye-LCOS, ixesha le-peak-to-valley parity yokugcina amandla ebhetri engasetyenziswanga ngu-2025, kwaye izinga lokuhla kweendleko emva koko lilinganiselwe.

isishwankathelo:
Ukuqwalasela umjikelo wangempela kummandla wokugcinwa kwamandla, kunokwenzeka ukuba iibhetri ezintsha zifuna ukuphuculwa kweendleko ezongezelelweyo, kwaye akukho ngqiqweni ukukhetha iibhetri ezidla umhlala-phantsi zokugcina amandla. Imodeli yezoqoqosho ngokuphinda isebenzise amandla njengoko ingundoqo ifuna ukuba umntu alindele ukuba iindleko ziqhubeke. Ukuya ezantsi, enye yimfuneko yokunikela ingqalelo kwinani lemijikelo engundoqo, eyahlulwe ngandlel’ ithile kwindlela yangoku yophuhliso loxinano lwamandla ezithuthi zombane ezisulungekileyo.
