Urhuluneli uMcGee usayina umthetho wembali ofuna i-100% yombane waseRhode Island ukuba ucinywe ngamandla avuselelekayo ngo-2033.
Umlilo webhetri yeTesla Megapack kwiVictoria Big Battery e-Australia kunyaka odlulileyo yayingumzuzu wokufunda kuTesla noNeoen.Umlilo waqhuma ngoJulayi ngelixa uvavanya iTesla Megapack.Umlilo wasasazeka kwelinye ibhetri kunye neeMegapacks ezimbini zatshatyalaliswa.Umlilo, eyahlala iiyure ezintandathu, “yayingaphumeleli ukhuseleko,” ngokutsho kweEnergy Storage News.
Uphando malunga nomlilo lwaqala emva kweentsuku ezimbalwa kwaye lwenziwa esidlangalaleni kutshanje.Iingcali ezivela kwi-Fisher Engineering kunye ne-Energy Security Response Team (SERB) yabhala ingxelo yobugcisa isithi umlilo ubangelwa ukuvuza kwe-coolant liquid.Oku kubangele i-arcing ngaphakathi kwe-Megapack iimodyuli zebhetri.
"Umthombo womlilo wawuyi-MP-1, kwaye eyona nto ibangela ukuba umlilo ubangele ukuvuza kwi-MP-1's inkqubo yokupholisa ulwelo eyabangela i-arcing kumandla ombane wemodyuli yebhetri yeMegapack.
"Oku kubangela ukuba iiseli ze-lithium-ion zemodyuli yebhetri zifudumale, nto leyo inokukhokelela ekusasazeni kweziganeko ezibalekayo kunye nomlilo.
“Ezinye izinto ezinokuba ngunobangela womlilo ziye zaqwalaselwa ngexesha lophando ngesizathu somlilo;nangona kunjalo, olu landelelwano lungasentla lweziganeko kuphela kwemeko ebangela umlilo ehambelana nabo bonke ubungqina obuqokelelweyo nohlalutyiweyo ukuza kuthi ga ngoku.
U-Teslarati waphawula ukuba i-Megapack ebambe umlilo yayikhutshwe ngesandla kwiinkqubo ezininzi zokubeka iliso, ulawulo kunye nokuqokelela idatha ekubeni yayikwimeko yokuvavanya ngelo xesha.Enye into ebangela ukusasazeka komlilo yisantya somoya.
Eli nqaku likwaphawula ukuba uTesla uphumeze iinkqubo ezininzi, i-firmware kunye nokunciphisa i-hardware ukunqanda iziganeko ezifanayo kwixesha elizayo, kubandakanywa ukuhlolwa kwenkqubo yokupholisa ngexesha le-Megapack.
UTesla uye wongeza izilumkiso ezongezelelweyo kwidatha ye-telemetry yenkqubo yokupholisa ukuchonga nokuphendula ekuvuzeni okupholisayo okunokwenzeka.Ukongezelela, uTesla ufake iihoods zentsimbi ezisanda kuyilwa ngaphakathi kophahla olugqunyiweyo lwazo zonke iiMegapacks.
Ingxelo ichaza ngezifundo ezininzi ezifunyenwe kumlilo weVictoria Great Battery (VBB).
“Umlilo weVBB uveze izinto ezininzi ebezingalindelekanga ezidityanisiweyo zenze ukuba umlilo uphuhle kwaye unwenwele kwiiyunithi ezikufutshane.Akuzange kukhe kwahlangatyezwana nazo ezi zinto kufakelo lwangaphambili lweMegapack, ukusebenza kunye/okanye uvavanyo lwemveliso olumiselweyo.hlanganisana.”
Ukongamela okulinganiselweyo kunye nokubekwa esweni kwedatha yetelemetry ngeeyure zokuqala ezingama-24 zokugunyaziswa, kunye nokusetyenziswa kweizitshixo zokutshixa izitshixongexesha lokugunyaziswa kunye novavanyo.
Ezi zinto zimbini zithintele i-MP-1 ekudluliseleni idatha ye-telemetry efana nokushisa kwangaphakathi kunye ne-alamu yephutha kwiindawo zokulawula zeTesla, ingxelo yathi.Ezi zinto zibeka izixhobo ezibalulekileyo zombane ezingaphumeleliyo ezifana nokuqhawula ukushisa okuphezulu kwimeko ethintelweyo kunye nokunciphisa umbane. Ukukwazi kwe-Megapack ukujonga kwangaphambili kunye nokuphazamisa iimeko zombane ngaphambi kokuba zinyukele kwisiganeko somlilo.
Ukususela kumlilo, uTesla uye wahlaziywa iinkqubo zayo zokulungisa, ukunciphisa ixesha lokudibanisa i-telemetry kwi-Megapack entsha ukusuka kwiiyure ze-24 ukuya kwi-1 iyure, kunye nokuphepha ukusetyenziswa kwe-keylock ye-keylock ye-Megapack ngaphandle kokuba iyunithi isebenza ngokusebenzayo.
Izifundo ezithathu ezinxulumene neli candelo.I-alamu yokuvuza okupholileyo, ukuqhawula ubushushu obuphezulu akunakuphazamisa impazamo yangoku xa iMegapack ivaliwe ngesitshixo.tshixa iswitshi, kunye nokuqhawulwa kweqondo lokushisa eliphezulu kunokukhutshazwa ngenxa yokulahlekelwa kwamandla kwisekethe yokuyiqhuba.
Ezi zinto zithintele i-MP-1's ukuqhawula ubushushu obuphezulu ekubekeni iliso ngokukhawuleza kunye nokuphazamisa iimeko zokuphazamiseka kombane ngaphambi kokuba kunyuke kwisiganeko somlilo, ingxelo ithi.
I-Tesla iphumeze imilinganiselo emininzi yokunciphisa i-firmware yokugcina zonke izixhobo zokukhusela umbane zisebenza kungakhathaliseki indawo yokutshixa isitshixo okanye inkqubo yenkqubo, ngelixa ubeka iliso ngenkuthalo kunye nokulawula isiphaluka samandla sokuqhawula ubushushu obuphezulu.
Ngaphaya koko, uTesla wongeze ezinye izilumkiso zokuchonga ngcono kwaye uphendule ukuvuza okupholileyo, ngesandla okanye ngokuzenzekelayo.
Nokuba lo mlilo ubangelwe kukuvuza okupholisayo, ukungaphumeleli okungalindelekanga kwamanye amacandelo angaphakathi eMegapack kunokubangela umonakalo ofanayo kwiimodyuli zebhetri, ingxelo yaphawula. ukuchonga ngcono, ukuphendula, ukulawula, kunye nokwahlula imiba kwiimodyuli zebhetri ezibangelwa kukusilela kwamanye amacandelo angaphakathi (ukuba ziyenzeka kwixesha elizayo).
Isifundo esifundiweyo apha yindima ebalulekileyo yeemeko zangaphandle kunye nokusingqongileyo (umzekelo umoya) kwi-Megapack fires.Kwaye kwakhona ubuthathaka obuchongiweyo kuyilo lophahla lwe-thermal oluvumela i-Megapack ukuya kwi-Megapack yokusasazeka komlilo.
Oku kubangele ukuhlaselwa kwamadangatye ngokuthe ngqo kwi-plastic overpressure vents etywina igumbi lebhetri ukusuka kuphahla olushushu, ingxelo ithi.
"Ibhetri ngaphakathi kwimodyuli yebhetri yeMP-2 ayiphumelelanga kwaye yabandakanyeka emlilweni ngenxa yomlilo kunye nobushushu obungena kwigumbi lebhetri."
I-Tesla iye yaqulunqa i-hardware yokunciphisa i-hardware ukukhusela i-overpressure vents.I-Tesla ivavanye oku, kwaye ngokufaka ii-insulated steel vent guards, ukuthotywa kuya kukhusela i-vents kwi-flame flame strike okanye ekungeneni komoya oshushu.
Ezi zibekwe phezu kweendawo zoxinzelelo olugqithisileyo kwaye ngoku zisemgangathweni kulo lonke ufakelo lweMegapack entsha.
I-fume hood yensimbi inokufakwa ngokulula kwi-Megapacks ekhoyo kwi-site.Ingxelo ithi i-vent hood isondela kwimveliso kwaye i-Tesla iceba ukuyibuyisela kwakhona kwindawo esetyenzisiweyo ye-Megapack kungekudala.
Izifundo ezifundwe apha zibonisa ukuba akukho lutshintsho olufunekayo kwiinkqubo zofakelo lweMegapack, kunye nokunciphisa ikhuselo lomoya kwindawo. Isehlo somlilo kwi-Megapack esecaleni kwi-intshi ezi-6 kuphela.
Ingxelo yongezelela ukuba ngaphambi kokulahlekelwa konxibelelwano kunye neyunithi kwi-11.57am, ukushisa kwebhetri yangaphakathi ye-MP-2 kuye kwanda ngo-1.8 ° F ukuya kwi-105.8 ° F ukusuka kwi-104 ° F, ekukholelwa ukuba kubangelwa ngumlilo ngokwawo. .Oku bekuyiyure ezimbini kwisehlo somlilo.
Ingxelo yongezelela ukuba ukusasazeka komlilo kwakubangelwa ubuthathaka kwiphahla lokufudumala kwaye kungekhona ngenxa yokutshintshwa kobushushu nge-gap ye-6-intshi phakathi kwe-Megapacks.I-Exhaust shield yokunciphisa idilesi yolu buthathaka kwaye iqinisekisiwe ngokusebenzisa iimvavanyo zomlilo zeyunithi, kubandakanywa. ezo zibandakanya ukucinywa kweMegapack.
Iimvavanyo ziqinisekisile ukuba nangona uphahla olushushu lubandakanyeka ngokupheleleyo emlilweni, i-overpressure vent ayiyi kuvutha.Iemvavanyo nazo ziqinisekisile ukuba imodyuli yebhetri yayingachaphazeleki ngokunyuka kwebhetri yangaphakathi engaphantsi kwe-1 degree Celsius.
