Bwanamkubwa McGee asayina malamulo akale omwe amafuna kuti 100% yamagetsi aku Rhode Island achotsedwe ndi mphamvu zongowonjezedwanso pofika 2033.
Moto wa batri wa Tesla Megapack ku Victoria Big Battery ku Australia chaka chatha unali nthawi yophunzira kwa Tesla ndi Neoen.Motowo unayamba mu July pamene akuyesa Tesla Megapack.Motowo unafalikira ku batri lina ndipo Megapacks awiri anawonongedwa.Motowo, zomwe zinatenga maola asanu ndi limodzi, zinali "kulephera kwa chitetezo," malinga ndi Energy Storage News.
Kafukufuku wokhudza motowo adayamba masiku angapo pambuyo pake ndipo adadziwika posachedwa.Akatswiri a Fisher Engineering ndi Energy Security Response Team (SERB) adalemba lipoti laukadaulo kuti motowo udachitika chifukwa cha kutayikira kwamadzi ozizirira.Izi zidapangitsa kuti arcing mkati mwa Megapack. ma module a batri.
"Magwero a motowo anali MP-1, ndipo chifukwa chomwe chimayambitsa motocho chinali kutayikira kwa makina oziziritsa amadzi a MP-1 omwe adayambitsa kukwera kwamagetsi amagetsi a module ya batri ya Megapack.
"Izi zimapangitsa kuti maselo a lithiamu-ion a module ya batri atenthedwe, zomwe zingayambitse kufalikira kwa zochitika zowonongeka ndi moto.
"Zina zomwe zingayambitse moto zidaganiziridwa panthawi yofufuza chifukwa cha moto;komabe, kutsatizana kwa zomwe zachitika pamwambapa ndizochitika zokhazo zomwe zimafanana ndi umboni wonse womwe wasonkhanitsidwa ndi kufufuzidwa mpaka pano.
Teslarati adanena kuti Megapack yomwe inagwidwa ndi moto idachotsedwa pamanja kuchokera ku machitidwe angapo owunika, kuyang'anira ndi kusonkhanitsa deta popeza inali muyeso yoyesera panthawiyo.Chinthu china chomwe chimayambitsa kufalikira kwa moto ndi liwiro la mphepo.
Nkhaniyi ikuwonetsanso kuti Tesla wakhazikitsa mapulogalamu angapo, firmware ndi zida zochepetsera kuti apewe zochitika zofananira mtsogolomo, kuphatikiza kuwunika kwadongosolo koziziritsa panthawi ya msonkhano wa Megapack.
Tesla wawonjezeranso machenjezo owonjezera ku data ya telemetry ya makina oziziritsa kukhosi kuti azindikire ndikuyankha kutulutsa koziziritsa komwe kumatha.
Lipotili limafotokoza za maphunziro angapo omwe aphunziridwa kuchokera kumoto wa Victoria Great Battery (VBB).
"Moto wa VBB udawonetsa zinthu zingapo zosayembekezereka zomwe zidaphatikizira kuti motowo ukule ndikufalikira kumadera oyandikana nawo.Izi sizinachitikepo pakuyika kwa Megapack, magwiridwe antchito ndi/kapena kuyesa kwazinthu zowongolera.sonkhanitsani.”
Kuyang'anira pang'ono ndikuwunika kwa data ya telemetry m'maola 24 oyamba otumizidwa, ndikugwiritsa ntchitozosinthira makiyipa kutumizidwa ndi kuyesa.
Zinthu ziwirizi zinalepheretsa MP-1 kutumiza deta ya telemetry monga kutentha kwa mkati ndi ma alarms olakwika kumalo olamulira a Tesla, lipotilo linati. Kuthekera kwa Megapack kuyang'anira ndikusokoneza magetsi asanayambe kuphulika.
Chiyambireni moto, Tesla yasinthanso njira zake zosinthira, kuchepetsa nthawi yolumikizana ndi telemetry ya Megapack yatsopano kuchokera ku maola 24 mpaka ola la 1, ndikupewa kugwiritsa ntchito makina a Megapack keylock pokhapokha ngati chipangizocho chikugwiritsidwa ntchito.
Maphunziro atatu okhudzana ndi gawoli. Alamu yoziziritsa kutayikira, kutentha kwakukulu sikungasokoneze vuto pamene Megapack yatsekedwa kudzera pa kiyi.loko losintha, ndi kutentha kwapamwamba kutsekedwa kungakhale kozimitsa chifukwa cha kutaya mphamvu kwa dera lomwe likuyendetsa.
Zinthuzi zidalepheretsa kutentha kwa MP-1's kutentha kwapang'onopang'ono kuyang'anitsitsa ndikusokoneza magetsi asanayambe kuphulika, lipotilo linati.
Tesla wakhazikitsa njira zingapo zochepetsera ma firmware kuti zida zonse zoteteza magetsi zizikhala zogwira ntchito mosasamala kanthu za malo osinthira keylock kapena dongosolo, komanso kuyang'anira ndikuwongolera kuwongolera kwamagetsi pakutha kwa kutentha kwakukulu.
Kupitilira apo, Tesla wawonjezeranso zidziwitso kuti athe kuzindikira bwino ndikuyankha kutayikira koziziritsa, kaya pamanja kapena zokha.
Ngakhale motowu udayambika chifukwa cha kutayikira koziziritsa, kulephera kosayembekezereka kwa zigawo zina zamkati za Megapack kukanapangitsa kuwonongeka kofananira ndi ma module a batri, lipotilo lidati. kuzindikira bwino, kuyankha, kuwongolera, ndikupatula nkhani zomwe zili mkati mwa ma module a batri chifukwa cha kulephera kwa zida zina zamkati (ngati zingachitike mtsogolo).
Phunziro lomwe laphunzira apa ndi gawo lofunikira la zochitika zakunja ndi zachilengedwe (mwachitsanzo mphepo) pamoto wa Megapack.Ndipo adazindikiranso zofooka mu kapangidwe ka denga lotentha zomwe zidalola kufalikira kwa Megapack ku Megapack.
Izi zidapangitsa kuti malawi amoto aziwombana ndi ma pulasitiki oponderezedwa kwambiri omwe amatseka chipinda cha batri kuchokera padenga lotentha, lipotilo lidatero.
"Batire mkati mwa module ya batri ya MP-2 idalephera ndipo idayamba kuyaka moto chifukwa cha malawi ndi kutentha komwe kumalowa muchipinda cha batri."
Tesla wapanga njira zochepetsera ma hardware kuti ateteze ma vents owonjezera.Tesla adayesa izi, ndipo poika alonda atsopano azitsulo zachitsulo, kuchepetsako kudzateteza mpweya kuti usawonongeke mwachindunji kapena kulowetsedwa kwa mpweya wotentha.
Izi zidayikidwa pamwamba pa ma vents oponderezedwa kwambiri ndipo tsopano ndizokhazikika pamakhazikitsidwe onse atsopano a Megapack.
Chophimba chachitsulo chikhoza kuikidwa mosavuta pa Megapacks yomwe ilipo pa site.Lipotilo likuti mpweya wotsekemera watsala pang'ono kupanga ndipo Tesla akukonzekera kubwezeretsanso ku malo a Megapack omwe amagwiritsidwa ntchito posachedwa.
Zomwe taphunzira apa zikuwonetsa kuti palibe kusintha komwe kumafunikira pakuyika kwa Megapack, ndikuchepetsa chishango cholowera mpweya m'malo mwake. chochitika chamoto mu Megapack yoyandikana ndi mainchesi 6 okha.
Lipotilo linawonjezera kuti isanathe kulumikizana ndi unit pa 11.57am, kutentha kwa batri ya MP-2 ya mkati idakwera ndi 1.8 ° F mpaka 105.8 ° F kuchokera ku 104 ° F, yomwe imakhulupirira kuti idayambitsidwa ndi moto womwewo. .Apatu padali maola awiri pachitika motowo.
Lipotilo linawonjezera kuti kufalikira kwa moto kunayambika chifukwa cha kufooka kwa denga la kutentha osati chifukwa cha kutentha kwa kutentha kupyolera mu kusiyana kwa 6-inch pakati pa Megapacks. zomwe zikuphatikiza kuyatsa kwa Megapack.
Mayesero atsimikizira kuti ngakhale denga lotentha likukhudzidwa kwambiri ndi moto, mpweya wotsekemera sudzawotcha.Mayesero adatsimikiziranso kuti gawo la batri silinakhudzidwe ndi kutentha kwa batri mkati mwa osachepera 1 digiri Celsius.
2. Gwirizanitsani ndi akatswiri omwe ali pamalopo kapena akutali (SMEs) kuti apereke opereka chithandizo chadzidzidzi ndi ukadaulo wofunikira komanso chidziwitso chadongosolo.
3. Kupereka madzi mwachindunji ku Megapack yoyandikana nayo kumawoneka kuti kuli ndi mphamvu zochepa, ngakhale kuti kupereka madzi ku zipangizo zina zamagetsi (kuganiza zosinthira) zomwe zimakhala ndi chitetezo chochepa cha moto pakupanga zingathandize kuteteza zida zimenezo.
4. Njira ya Megapack yopangira chitetezo cha moto imaposa mapangidwe ena osungira mphamvu za batri (BESS) ponena za chitetezo chachangu.
5. Lipotilo linanena kuti bungwe la Environmental Protection Agency linanena kuti mpweya wabwino unali wabwino patatha maola awiri moto utatha, kutanthauza kuti motowo sunabweretse mavuto kwa nthawi yaitali.
6. Zitsanzo za madzi zimasonyeza kuti pali mwayi wochepa wa moto womwe umakhala ndi zotsatira zazikulu pa kuzimitsa moto.
7. Kutengapo gawo m'mbuyo kwa anthu mu gawo lokonzekera pulojekiti n'kofunika kwambiri. Kumathandiza Neoen kusinthira mwamsanga madera akumidzi pamene akukamba za zovuta ndi zovuta.
8. Pakabuka moto, kuonana maso ndi maso ndi anthu ammudzi nkofunika kwambiri.
9. Lipotili likunena kuti komiti yoyang'anira ogwira nawo ntchito yotsogola yopangidwa ndi mabungwe akuluakulu omwe akukhudzidwa ndi vuto ladzidzidzi ingathandize kuwonetsetsa kuti mauthenga aliwonse amtundu wa anthu ali pa nthawi yake, ogwira ntchito, ogwirizana mosavuta, komanso omveka bwino.
10. Phunziro lomaliza ndiloti kugwirizanitsa bwino pakati pa anthu ogwira nawo ntchito pamalowa kumapangitsa kuti pakhale njira yofulumira komanso yowonjezereka yoperekedwa pambuyo pamoto.Zimapangitsanso kutayika kwachangu ndi kotetezeka kwa zida zowonongeka komanso kubwerera mwamsanga kwa malo ku ntchito.
