Ugcino lwebhetri yoRhwebo oluModyuli: Ukusuka kwiZakhiwo eziZinzileyo ukuya kwiiNkqubo zeKhabhinethi eziDityanisiweyo

Ukugcinwa kwebhetri yemodyuli yorhwebo yakhiwe malunga nombono omnye: yongeza umthamo ngokongeza iiyunithi, hayi ngokukrazula into esele ikhona. Ubungakanani benkqubo yomthwalo wanamhlanje, yandisa xa imeko yeshishini itshintsha - rhoqo ngaphandle kokutshintshwa kweentambo ezinkulu okanye ukutshintshwa kwezixhobo.

Enyanisweni, loo ngcamango ibonakala kwiifomathi ezimbini. Iimodyuli zebhetri ezizinzileyo - iiyunithi ze-LFP nganye kuluhlu lwe-5–10 kWh eziqhagamshela ngeebhasi - zisebenza kakuhle kwiziza zorhwebo ezincinci apho imfuno iyonke ihlala ngaphantsi kwamakhulu amabini eekilowatt- zeyure. Izixokelelwano zekhabhathi ezidityanisiweyo zithatha ukudibanisa okufanayo{7}}musa{8}}indawo yengqiqo kwaye iyipakishe kwinqanaba eliphezulu: iiseli zebhetri, iPCS, iBMS, i-EMS, ulawulo lwe-thermal, kunye noxinzelelo lomlilo ngaphakathi kwendawo ebiyelweyo yokumelana nemozulu, iqala malunga nama-200 kWh ngeyunithi nganye. Zombini zikala ngokudibanisa iiyunithi. Umahluko kukuba yintoni "iyunithi", kwaye ingakanani indibaniselwano umenzi ayiphathayo ngaphambi kokuba ifike kwindawo yakho.

Indawo yokuNgena yeeModyuli eziStackable

Imodyuli yebhetri ebekekileyo isondele kwiplagi-kwaye{1}}yadlala njengoko ugcino lwentengiso lufumana. Iyunithi nganye - idla ngokuba yi-48V okanye i-51.2V LFP ibhloko ebambe i-5–10 kWh - ine-BMS yayo yokujonga amandla ombane weseli, ubushushu, kunye nemo yokutshaja. Zipakishe, uqhagamshele ngeebhasi okanye{10}}ziqhagamshelo ezikhawulezayo, zidibanise nesiguquli esihambelanayo, kwaye inkqubo ibona ibhanki enye yebhetri.

Isizathu sokuba le fomati ibanjwe kwiiprojekthi ezincinci ze-C&I ziyasebenza. Imodyuli enye inobunzima be-45-55 kg. Abafakeli ababini banako ukuyithwala. Ukwandisa nge-10 kWh kuthetha ukongeza ibhokisi enye kunye nemizuzu eli-15 yokusebenza, hayi ukulungisa ngokutsha igumbi lombane. Kwaye ngenxa yokuba imodyuli nganye iqhuba impazamo yeBMS ezimeleyo, iseli ebuthathaka kwimodyuli enye ayithathi phantsi umtya - iBMS itsala loo modyuli ngaphandle kweintanethi ngelixa ezinye ziqhubeka nokusebenza. Oko kubalulekile kwiziko lezorhwebo apho ixesha lokuphumla elingacwangciswanga ngexesha leeyure zokuhlawula okuphezulu kunexabiso ledola elidityaniswe kuyo.

Apho iimodyuli ezicwangcisiweyo ziqala ukusengxakini kuxa ufuna ngaphezulu kwamakhulu amabini eekilowatt-iiyure, okanye xa umfutho webhayisikile utyhala udlule kanye{1}}{2}}usuku oluthambileyo lokutsheva kwimpendulo yemfuno endlongondlongo okanye ummiselo ophindaphindiweyo. Ngelo xesha, inani -loqhagamshelo lwemodyuli, imida yolawulo olusasaziweyo lwe-thermal, kunye nokuntsonkotha kokungqamana kweeyunithi ezincinci ze-BMS ziqala ukusebenza ngokuchasene nawe. Kulapho iikhabhinethi ezidibeneyo zithatha khona.

Ngaphakathi kwiKhabhinethi eDityanisiweyo: Indlela iSystems engaphantsi iDityaniswa ngayo

Ukubonisa ukuba injani iyunithi yemodyuli yodibaniso oluphezulu-ijongeka njani, nantsi indlela isiseko senkqubo emithandathu emiselwa ngayo kwikhabhinethi yorhwebo yangaphandle - kusetyenziswa eyethu.125kW/241kWh inkqubonjengomzekelo omnye wendlela olu didi lwemveliso lwakhiwe ngayo ngokuqhelekileyo.

Sibhale ngaphambili malunga nokuba njaniUmgangatho we-BMS umisela{0}}umsebenzi we-BESS wehlabathirhoqo kunomgangatho weseli wenza - lo ngumaleko apho idlala khona.
• Utshintshiselwano olungatshintshiyo (STS) luphatha igridi-ukuya{1}}kucinywe{2}}utshintsho lwegridi ngaphantsi kwe-20 millisecond - ngokukhawuleza ngokwaneleyo ukuba iiseva, isibandisi, kunye nolawulo lwemveliso lungabhalisi ukuphazamiseka. Ayizizo zonke iikhabhinethi ezibandakanya enye, kodwa kwizibonelelo apho i-gap yokuqalisa i-10-yesibini iyityala, ithatha indawo yesidingo se-UPS eyahlukileyo.
• Ulawulo lobushushu: iinguqulelo zomoya{0}}ezipholileyo zisebenzisa i-IP55 yokungena komoya ngenkani, eyanele ukukhwela ibhayisekile okuphakathi kwimozulu epholileyo. Ulwelo-ulungelelwaniso olupholileyo luqhuba iipleyiti ezibandayo zeglycol ze ±2 iseli yeqondo-ukuya{6}}ukufana kweseli - okuxabisa ixabiso eliphezulu{8}}lomjikelo okanye kushushu{9}}nokusasazwa kwemozulu.
• Ukunciphisa umlilo kuqhuba izigaba ezithathu: ukufumanisa umsi / igesi, ukuphendula ngokukhawuleza kwe-aerosol, kunye ne-perfluorohexanone yezikhukhula ukuba i-thermal runaway isasazeka. Uziro-iarhente ezishiyekileyo, ngoko ke inkqubo inokubanakho ukuqalisa kwakhona kunokuba icinywe.

Nganye kwezi khabhinethi yinxalenye epheleleyo. Ukwandiswa kuthetha ukongeza enye. Ikwakwafanayo nokudibanisa{2}}musa{3}}ukubuyisela umthetho-siseko njengemodyuli ezipakishwayo, nje kwisikali esahlukileyo - kunye nodibaniso osele lwenziwe kumzi-mveliso endaweni yesayithi yakho.

Yeyiphi eYona iSombulula iFomathi kuMashishina{0}}obungakanani

Ingaba yakhiwe kwiimodyuli ezigciniweyo okanye zihanjiswe njengekhabhinethi edibeneyo, ixabiso lentengiso liyafana: ubungakanani banamhlanje, ukwandisa xa kufanelekile.

Ukucheba okuphezulu kulapho uninzi lweeprojekthi zokugcina i-C&I ziqala khona. Ivenkile yokuvelisa encinci etsala i-150 kW imfuno ephezulu kwiindleko zemfuno ye- $ 15/kW ihlawula i-$2,250 ngenyanga nje ngeso spike - idla ngokuqhutywa sisixhobo esinye esinzima esisebenza ngexesha lefestile yeyure ezi-2 emva kwemini. Inkqubo yemodyuli ye-100 kWh icheba i-50 kW ukusuka kuloo ncopho, yonga i-750 yeedola / ngenyanga, kwaye ayifuni ukuba ivenkile iqikelele ukuba umgca wesibini wemveliso uyeza kunyaka ozayo. Ukuba kunjalo, bongeza umthamo. Ukuba akunjalo, abakhanga ngokugqithisileyo.

Ukusetyenziswa kweSolar{0}}kulandela ingqiqo efanayo. Indawo yokugcina impahla enama-50 kW eluphahleni uluhlu lwentsalela ethumela ngaphandle nge- $ 0.04–$0.08/kWh inokuphinda iqondise loo mandla ukuphelisa ukusetyenziswa kwangokuhlwa nge-$0.20–$0.35. Ubungakanani obufanelekileyo bogcino buxhomekeke kwiprofayile yomthwalo etshintshayo njengoko ishishini litshintsha - uyilo lwemodyuli lufunxa oko.

Ugcino lwamandla luyayijikeleza. Umsebenzi wokuthengisa ufuna i-30 kWh ye-POS, ifriji, kunye nokhuseleko kwi-4-yure yokucima. Igumbi elincinci ledatha lifuna i-80 kWh. Ukuqala okuncinci kunye nokukala okusekwe kumava okucinywa kwenyani kubetha ukuqikelela kwinani kwaye ufumanise ukuba umkhulu kakhulu okanye ubhentsisiwe.

Ukusetyenziswa Nini

Iimodyuli ezizinzileyo zikholisa ukwenza intsingiselo kukusasazwa korhwebo oluncinci - ivenkile, uvimba omncinci, isakhiwo seofisi - apho ugcino lulonke luhlala ngaphantsi kweeyure ezingamakhulu eekilowatt{2}} kwaye ukukhwela ibhayisekile kuphakathi. Ixabiso lokungena liphantsi, ukufakela kuyakhawuleza, kwaye ukongeza umthamo kamva kuthe ngqo.

Izinto ezininzi zityhalela iprojekthi kwiikhabhathi ezidibeneyo endaweni yoko:

• Ugcino lufuna ukuya kuluhlu -lwamakhulu{1}} lwekWh nangaphezulu, apho ukulawula amatyeli emodyuli nganye kwenza uqhagamshelwano{2}}lobunzima benqaku.
• Ukukhwela ibhayisekile yonke imihla - ukucheba okuphezulu kunye nempendulo yemfuno, okanye imijikelo emininzi ngosuku - apho umzi-mveliso{2}}ulawulo oludityanisiweyo lwe-thermal lubambe ngcono kunokupholisa okusasazwe kwiimodyuli ezahlukeneyo.
• Indawo enyanzelweyo yonyawo, apho uxinano lwamandla ngemitha yesikweri nganye lubalulekile
• Ukukhethwa kokuhanjiswa kwe-turnkey: indawo ebiyelweyo, enye yokugunyaziswa, umnini wewaranti enye

Akukho mgca ucocekileyo phakathi kwezi zimbini. Indawo ye-200 kWh yokukhwela ibhayisekile ngobunono inokusebenza nokuba yeyiphi na indlela. Indawo engama-200 kWh eqhuba ukutsheva okundlongo kwimihla ngemihla kunye nempendulo yemfuno ihlala isebenza ngokuthe kratya kunye nenkqubo edibeneyo aphoI-BMS, ulawulo lwe-thermal, kunye nokuguqulwa kwamandla kuyilwe kunye.

Kutheni i-LFP kuzo zombini iiFomati

Phantse yonke imodyuli yebhetri yorhwebo - ebekekileyo okanye ikhabhathi - isebenzisa iiseli ze-lithium iron phosphate. Ukubola kobushushu be-LFP kuhlala kwi-270℃xa kuthelekiswa ne-210℃ye-NMC. Laa 60{7}}yeqondo lomda yinto eyenza ukuba usasazo lwentengiso lwangaphakathi lusebenze ngaphandle koxinzelelo olubanzi lweziseko zophuhliso. I-NMC ipakisha amandla amaninzi ngelitha nganye, kodwa ifestile ecutheneyo yobushushu iqhubela phezulu kwindawo ebiyelweyo kunye neendleko zocinezelo ezihlala zitya inzuzo yoxinano.

I-LFP nayo ijikeleza ixesha elide. Incopho yoRhwebo-umsebenzi wokutsheva kuma-80% ubunzulu bokukhupha ngokuqhelekileyo ivelisa i-5,000–6,000 yemijikelo epheleleyo - 13+ iminyaka yokusetyenziswa kwemihla ngemihla - phambi kokuba ibhetri ifikelele kwi-80% yomthamo wokuqala. Uvavanyo lweSandia National Laboratories lubonise ukuba i-LFP ifikelela kwimijikelo ye-10,000 phantsi kweemeko ezilawulwayo. Ngokuchasene ne-NMC's 2,000–4,000 uluhlu lomjikelo, ixabiso lilonke lokuthelekisa ubunini kunzima ukuxoxa. Kwaye ngenxa yokuba i-LFP isebenzisa i-iron kunye ne-phosphate endaweni ye-cobalt kunye ne-nickel, amaxabiso ezinto ezikrwada azinzile ngakumbi - ezifanelekileyo xa uthenga iimodyuli zokwandiswa kunyaka wesi-4 ngesiseko seendleko ekufuneka uziqikelele namhlanje.

Ubungakanani: Qala kancinci kunokuba ucinga

Eyona mpazamo ixhaphakileyo kwiiprojekthi zokugcina iimodyuli zorhwebo kukuthenga kakhulu ngaphambili. Inqaku elipheleleyo loyilo lwezakhiwo kukuba akufuneki uqikelele kanye ngosuku lokuqala.

Ukutsheva okuphezulu, tsala iinyanga ezili-12 zedatha yemitha yekhefu yemizuzu eli-15. Fumana xa imfuno iphezulu, ihlala ixesha elingakanani, ukuba kungakanani ukucheba kukuwisa kwinqanaba eliphantsi. Indawo yokuzoba i-300 kWh/ngosuku isoloko ifuna kuphela i-50–80 kWh yokugcina ukuba incopho igxininiswe kwifestile eqikelelwayo. Qala apho. Qinisekisa kwimijikelo emibini yokuhlawula. Emva koko uthathe isigqibo sokuba ngaba ukwandiswa kwenza ingqiqo yezoqoqosho ngokusekelwe kwidatha yangempela.

Inqaku kwiukusebenza kwebhetri yombane ophezulu kunye nokulinganisaigquma amandla ombane-isigqibo sodidi ngobunzulu obungakumbi - phezulu{2}}iimfumba zevolthaji zihambisa malunga ne-5% engcono yokujikeleza{4}}uhambo olunempumelelo kuneenkqubo ezingama-48V kunye nokunciphisa iindleko zocingo kwiintambo ezinde zorhwebo.

Umgaqo omnye ofanele ukuphinda: musa ukudibanisa iimpawu zemodyuli okanye amandla ngaxeshanye. Ukuphunyezwa kwe-BMS okwahlukeneyo kusebenzisa imiqobo yamandla ombane eyahlukeneyo kunye -nengqiqo yomda yangoku.
