Ithini isistimu yokugcina amandla ekhabhinethi yangaphandle?

 

Iuhlelo lokugcina amandla ekhabhinethi yangaphandleimele okuhlanganisiweisixazululo sokugcina amandla ebhethri(BESS) yakhelwe ukuthunyelwa ezindaweni zangaphandle lapho izithiyo zesikhala nokuchayeka kwemvelo kuletha izinselelo zokusebenza. Ihlukaniswa namasistimu aneziqukathi ngobude bawo obuncane kanye nasezindlini zokuhlala{1}}ngokucaciswa kwebanga lezentengiso, leli khabhinethi{2}}ifomu elithi BESS lihlanganisa amamojula ebhethri e-lithium iron phosphate (LFP),amasistimu okuguqula amandla (PCS), amasistimu okuphatha ibhethri (BMS), okokusebenza kwezimiso ezishisayo, nezindlela zokucindezela umlilo ngaphakathi kwendawo evalekile elinganiselwe ye-IP55 noma i-NEMA 3R-.

Kungani kukhona i-computer caseizilinganisokubalulekile?

Nansi into abantu abayiphuthelayo lapho bethenga indawo yokugcina amandla: ikhabethe akulona nje ibhokisi.

Cabanga ngakho. Unendawo encane yokukhiqiza. Mhlawumbe indawo ethengisa izimoto enamashaja e-EV aphumile. Isibhedlela sasemakhaya esingakwazi ukuphelelwa amandla. Izixazululo zeziqukathi ezingu-20-ezibusa insiza-yesikali semakethe-lezo ngeke zilingane. Futhi powerwalls zokuhlala? Akukho ndawo eseduze nejusi eyanele.

Ikhabhinethi yangaphandle igcwalisa lesi sikhala, nakuba ngokweqiniso, imboni ithathe iminyaka ukuthola lokhu. Ukufakwa kwezentengiselwano kwangaphambi kwesikhathi ngokuvamile kwakusho ukufaka kabusha ama-rack ebhethri angaphakathi ezindlini ezingamelana nesimo sezulu, futhi imiphumela yayi... ixutshwe, okungcono kakhulu. Izinkinga zokujiya. Amaphupho amabi ngokuhamba ngebhayisikili. Isifaki esisodwa engifunde ngaso sichaza ukuthola idamu ngaphakathi kwekhabhinethi okuthiwa ivaliwe ngemuva kobusika obubodwa baseMinnesota.

Imiklamo yesimanje ixazulule kakhulu lezi zinhlungu zekhanda. Ukwakhiwa kwensimbi noma i-aluminium. Ukufakwa odongeni okukabili-kukabili. Umcabango wangempela ufaka endleleni umoya ohamba ngayo entweni.

Izingxenye Eziyinhloko (Futhi Iziphi Ezibalulekile Empeleni)

Izinto zokumaketha zizoklelisa zonke izingxenye njengokuthi zonke zibaluleke ngokulinganayo. Abanjalo.

Amabhethri ngokwawongokusobala zigxeka. Ikhemistri ye-LFP ilawula le segimenti ngesizathu esihle{1}}umkhawulo wokubaleka oshisayo uhlala ngaphezu kwama-degree angu-250, ngaphezu kwalokho okubekezelelwa yi-NMC noma i-NCA chemistries. Ngeke ubone amavidiyo omlilo ahlasele amaphrojekthi wangaphambi kwesikhathi wokugcina igridi. I-tradeoff ingumthamo wamandla ophansi, kodwa uma wakha okuthile okuzohlala kungagadiwe ngemuva kwebhilidi iminyaka eyishumi nanhlanu, ukuphepha kuyawina.

Ukuphatha okushisayo yilapho amaphrojekthi ehluleka khona ngempela. Ukupholisa komoya kusebenza kahle ezilinganisweni zokukhishwa kokungu-1C noma ngaphansi-okuhlanganisa izinhlelo zokusebenza eziningi ze-C&I, izimo zokushefa okuphezulu kakhulu, lolo hlobo lwento. Phusha ngale kuka-2C futhi ukhiqiza ukushisa ngokushesha kunokuba i-convection yemvelo ingakuhlakaza. Abanye abakhiqizi sebeqalile ukuhlanganisa ukupholisa uketshezi, izixazululo ze-glycol ezijikelezayo ngamapuleti abandayo ahlanganiswe phakathi kwezitaki zamaseli. Izinzuzo zokusebenza kahle zingokoqobo. Kanjalo nezinkinga zesondlo.

I-PCS iphethe ukuguqulwa kwe-DC-AC. I-BMS iqapha ama-voltage amaseli namazinga okushisa. I-EMS ixhumanisa yonke into. Lezi zibalulekile, ngokusobala. Kodwa ziwubuchwepheshe obuvuthiwe njengamanje. Umehluko phakathi kwabahlinzeki bempahla kwenzeka kumklamo oshisayo kanye nobunjiniyela bendawo ebiyelwe.

Ukucatshangelwa kokufakwa Akekho Okhuluma Ngayo

Lezi zincwajana zikhombisa lamakhabethe ehlezi kahle kumaphedi kakhonkolo, mhlawumbe enamatshe okuhlobisa eduze kwawo. Iqiniso liyi-messier.

Ukulungiselela phansi kubaluleke ngaphezu kwalokho abantu abaningi abakuqaphelayo. Ukuhlanganisa amanzi endaweni ephansi kusheshisa ukugqwala kokufakiwe kwekhebula futhi kunga{1}}ngaphansi kwezimo ezingalungile{2}}kudale amaphutha aphansi. Enye insiza engahlangana nayo kwadingeka ukuthi ithuthe ukufakwa kwekhabhinethi okuyisithupha phakathi neminyaka emibili yokugunyazwa ngoba iziza zakuqala zaphenduka amachibi esizini.

Izidingo zokusula ziyahlukahluka ngokuya ngendawo ethile, kodwa ngokuvamile lindela ukuvunyelwa okusemaceleni okungu-3-okungamafidi angu-6 nokufinyelela ngaphambili okungamafidi angu-6. Amakhodi omlilo ezifundeni ezithile agunyaza ukuhlehla okwengeziwe kusuka ezakhiweni. Futhi ngikufisela inhlanhla yokuthola impendulo eqondile ekuvumeleni imigqa yesikhathi-ngibone amaphrojekthi afanayo ezifundeni eziseduze ethatha amasonto amathathu nezinyanga eziyisishiyagalolunye ngokulandelana.

Ukuxhumana kukagesi kuwuhambo lwakho siqu. Amakhabethe amaningi angaphandle aqondise okungu-400V noma okungu-480V{3}}kokuxhunywa kwegridi yezigaba ezintathu. I-interface ye-transformer (uma udinga i-voltage stepping) ingangeza u-$15,000-40,000 ezindlekweni zephrojekthi. Amaswishi e-Bypass. Nqamula izindlela. Ukucatshangelwa kwe-Arc flash. Ikhabhinethi ngokwayo ingase ibe yi-turnkey, kodwa ukufakwa akuvamile

Umbuzo Wokuphepha

Lokhu kusifanele isigaba sako, nakuba sengike ngathinta kuso.

Amabhethri e-LFP awashi kalula. Yiqiniso lokhu. Okuyiqiniso futhi: basengakwazi ukuzwa izenzakalo ezishisayo ngaphansi kwezimo zokuhlukunyezwa, futhi ikhabhinethi yangaphandle igxilisa amandla amaningi agcinwe endaweni encane.

Eminye imiklamo emisha iqhubekela phambili-ekupholiseni kokucwiliswa kawoyela okusebenza kanyekanye njengesivimbeli umlilo. Izincwadi zocwaningo zibonisa ukuthi lezi zinhlelo zinganciphisa kakhulu ingcuphe yokusabalalisa okuphumayo okushisayo, nakuba idatha yokuthunyelwa kwenkambu ihlala inomkhawulo.

Okungikhathaza kakhulu kunezimo zokwehluleka okuyinhlekelele ukuwohloka kancane kancane okungabonakali. Iseli elikhula ukumelana nangaphakathi okuphezulu. I-fan epholile iqala ukuguga. Laba abazimemezeli ngama-alamu. Zibonakala njengokwehla{4}}uhambo oluya nokubuya, kancane, phakathi nezinyanga. Amasistimu okuqapha abamba lokhu... uma othile empeleni ebuka amadeshibhodi.

Izicelo Ezisebenzayo

Imakethe ye-C&I izamukele ngempela lezi zinhlelo. Hhayi endaweni yonke, futhi ngaphandle kokwehluleka okuthile endleleni, kodwa umkhondo ucacile.

Ukushefa okuphezulukuhlala kuyicala lokusetshenziswa eliyinhloko. Amazinga kagesi wezentengiso ngokuvamile ahlanganisa izindleko zokufunwa okusekelwe ekudonsweni kwamandla kwamaminithi angu-15{5}okuphakeme kakhulu phakathi nesikhathi sokukhokha. Ikhabhinethi engu-100kW/215kWh ingawenza aphansi lawo ma-spikes, ilethe ukonga kwangempela-ngezinye izikhathi okwanele ukuthethelela izindleko zemishini phakathi neminyaka engu-3-4 kuye ngesakhiwo sesilinganiso.

Amandla ekhophi yasenqolobaneniiyakhula, ikakhulukazi ngemva kokuba izehlakalo zokwethenjwa kwegridi zibonise ukuthi ngisho nezifunda ezithuthukisiwe zingabhekana nokunqamuka okunwetshiwe. Amakhabethe asekela ukusebenza kokuqala okumnyama ekucushweni okuningi, nakuba i-handoff ingenamthungo njenge-UPS yendabuko. Uma udinga ukuphazamiseka okunguziro ngemithwalo ebalulekile, usabeka izixazululo.

Ukuhlanganiswa kwelangaisebenza kahle kodwa idinga ukulinganisa ngokucophelela. Umthamo wesitoreji kufanele ufane namahora ambalwa okukhiqiza ngokweqile. Izinhlelo ezingaphansi kosayizi zimosha nje ukukhiqizwa kwensalela; amasistimu amakhulu awakaze afinyelele ekujuleni komjikelezo okukhulisa i-ROI.

Ezinye izinhlelo zokusebenza ezisafufusa-zisekela ukushaja kwe-EV okusheshayo, ukubamba iqhaza kwamasevisi egridi{1}}kubonisa isithembiso kodwa kuhlala kusenesikhathi-kusesiteji-sesikali sekhabhinethi.

Okufanele Ukubheke Empeleni

Uma uhlola lawa masistimu, ziba izihloko zezindaba zamanani isikhashana. Isilinganiso se-nameplate esingu-215kWh esingu-25℃asikutsheli lutho{3}}ngokusebenza komhlaba kwangempela ehlobo lase-Texas noma ubusika base-Wisconsin.

Buza mayelana:

Ibanga lokushisa lokusebenza. Amasistimu angcono aphatha -30℃ukuya ku-+55℃ngaphandle kokuhlehlisa. Amasistimu amancane abeka imikhawulo yenkokhiso engaphansi kwedigri engu-0 engawenza angabi nalusizo ekusetshenzisweni kwesitoreji ngobusuku obubodwa ezindaweni ezibandayo.

Umthamo osebenzisekayo uma uqhathanisa negama. Abanye abakhiqizi bacaphuna umthamo ogcwele; abanye bakhela ezinqolobaneni. Ufuna ukwazi ukuthi yini etholakala ngempela ekujuleni okungama-80% kokukhishwa ngemuva kweminyaka emithathu yokuhamba ngebhayisikili.

Imigomo yewaranti ngaphezu kwesikhathi eside. I-Capacity Fade iqinisekisa udaba. Kanjalo nokubhala okuhle mayelana nokuthi kusho "ukusetshenziswa okuvamile." Ngibone iziqinisekiso zichithwa ngenxa yemininingwane yokufaka engakaze ikhulunywe njengezimfuneko.

Indlela yokuphatha ezishisayo. Ukupholisa umoya noma uketshezi? Yiliphi izinga lokushisa le-ambient elishayela isistimu ekulahlekeni kokuvikela? Uyini umthwalo we-parasitic wesistimu yokupholisa ngokwayo?

Ukubonakala kweketango lokunikezela. Akhiwe kuphi amaseli? Ikuphi umhlangano wokugcina? Lokhu kuthinta izikhathi zokuhola, isevisi yesiqinisekiso, futhi ngokwandayo, ukufaneleka kwezinhlelo zokukhuthaza.

I-Cost Reality

Ukucaca kwentengo kule makethe kubi. Zonke izingcaphuno "zisekelwe kwisicelo." Kodwa uma sikhuluma nje, lindela u-$500-800/kWh kumasistimu ekhabethe le-turnkey ebangeni lika-100-300kWh. Ukufakwa kwengeza enye i-15-25% kuye ngobunkimbinkimbi besayithi.

Lezi zinombolo zilokhu zehla-amabhethri ngokwawo ehle cishe ngo-90% eminyakeni engamashumi amabili{2}}kodwa kungenzeka sisondela ezintengo eziphansi ngasohlangothini lwekhemistri. Ibhalansi{{4}ye-yezindleko zesistimu ifakazelwe ukuthi iyanamathela.

Ukuthi umsebenzi wezomnotho uyasebenza kuncike ngokuphelele esimweni sakho esithile. Amanani kagesi. Funa izakhiwo zokushaja. Izikhuthazo ezitholakalayo. Amaphrofayili esizukulwane selanga uma kufanelekile. Ukuqagela kwe-Generic ROI akusizi lapha. Thola{6}}ukuhlaziywa okuqondile kwesayithi noma ungazihluphi.

Iphokophelephi Lobu buchwepheshe

Abakhiqizi baphusha ukuminyana kwamandla phezulu ngokukhiqiza umkhiqizo ngamunye. Ikhabhinethi engu-215kWh ebidinga ukunyatheliswa kwangaphandle okuphelele eminyakeni emihlanu edlule manje ingena kokuthile okuncane ngo-30%. Ukupholisa uketshezi kuthuthela phansi kusuka kumasistimu aneziqukathi. Ukuqapha okukude sekuvuthwe kwaze kwaba seqophelweni lapho ukusebenza okungagadiwe kusebenza ngempela kunokuba kube yizifiso.

Ukuziphendukela kwemvelo okungabonakali kwenzeka ekulawuleni ubuhlakani. Ukufunda ngomshini{1}okususelwe kokubikezela ukuthunyelwa. Ukusabela okunamandla-kumanani entengo kagesi esikhathi sangempela. Imodeli yokuwohloka okuzenzakalelayo elungisa imingcele yokusebenza ukuze inwebe ukuphila okusebenzisekayo.

Ukuthi konke lokhu kuhlangana kwezentengiso, ukufaka-futhi{1}}kukhohlwe ingqalasizinda kusazobonakala. Umugqa wethrendi uphakamisa ukuthi yebo, ekugcineni. Umugqa wesikhathi? Noma ubani othi uyazi uyaqagela.

Isitoreji samandla sekhabhinethi yangaphandle sithatha indawo ethile kunguquko ebanzi yokufakwa kukagesi{0}}enkulu kakhulu ezindlini, incane kakhulu eziteshini ezisetshenziswayo, ezilungele izindawo zemboni yezohwebo nezilula ezihlanganisa ingxenye enkulu yokusetshenziswa kukagesi endaweni eyakhelweyo. Akubona ubuchwepheshe obukhazimulayo. Ngeke kube sematheni. Ngokuya ngokuya, izosebenza ngokuthula ngemuva, ishefa iziqongo futhi igcine ukukhanya kwelanga, okungaba yilokho kanye okubalulekile.
