Izisombululo zeBESS ezikwaziyo ukulinganiswa kwiiHub zokutshaja ze-EV ezinamandla aphezulu

Impendulo ekhawulezileyo

Ukuguquguquka kombane yeyona nto ibalulekileyo kwii-hubs zokutshaja ze-EV ezinamandla aphezulu: indawo yanamhlanje enetshaja ezine kufuneka ibe yindawo ye-megawatt yetshaja ezilishumi elinesithandathu ngomso ngaphandle kokwakhiwa ngokutsha okutshajayo nokutshintshwa. Izisombululo ze-BESS zeModular ziphendula oku ngezinto ezintathu ezikhula kunye - iiyunithi zekhabhinethi (120–300 kWh), iitshaja ze-BESS ezidibeneyo (200–625 kWh ezinokutshaja ezakhelwe ngaphakathi), kunye neenkqubo ezikwisikhongozeli (1–2 MWh+) - zonke zilawulwa yi-EMS enye ephatha indawo yokugcina, iitshaja, kunye noqhagamshelo lwegridi njengomthombo omnye. Ngenxa yokuba amandla ebhetri kunye neemodyuli zamandla zongezwa ngokwanda ngelixa indawo isebenza, abaqhubi banokuchitha imali ngokwezigaba ngokukhula kwetrafikhi, bagcine uqhagamshelo lwegridi luncinci, kwaye baqhube utshintsho ukusuka kwi-120 kW ukuya kwi-960 kW nangaphezulu ukuya kwi-MCS megawatt yokutshaja. Umthetho ophambili: yenza ubungakanani boqhagamshelo lwegridi yetrafikhi yanamhlanje, yenza ubungakanani boyilo lwe-BESS lwangomso.

Izinto ezibalulekileyo ekufuneka ziqwalaselwe

• Izinto ezisetyenziswa kwimodular form factors — ikhabhinethi, i-integrated, container — vumela ii-hubs ukuba zilinganise umthamo kwi-kW kunye ne-kWh ngaphandle kokuyeka ukusebenza.
• Ukusasazwa kwe-BESS ngokwezigaba kulungelelanisa inkcitho yemali kunye nokukhula kwezithuthi kwaye kuthintela ukwakhiwa kakhulu ngosuku lokuqala.
• I-EMS ekwabelwana ngayo yintsika yokwandisa umbane: ulawulo olunye lokugcina, iitshaja, kunye neenkonzo zegridi kuyo nayiphi na indlela.
• Ii-hubs ezinamandla aphezulu (480 kW–2 MW) zifuna iimodyuli zamandla ezipholisiweyo lulwelo kunye nolawulo lobushushu bebhetri ukuze zigcine imveliso elinganisiweyo.
• Iindawo ezixineneyo ngegridi zisebenzisa iBESS ukukhulisa amandla okutshaja ngaphandle kokulinda ukuphuculwa kwetransformer.

Ingxaki Yokukala Ekutshajeni Okunamandla Aphezulu

Imfuno yokutshaja koluntu ayikhuli ngendlela ethe tye — iyanyuka. Ihabhu yendlela evula ngeetshaja ezine ze-120 kW inokubona ukusetyenziswa kathathu kwiinyanga ezingama-24 njengoko iinqanawa ezikufutshane zisebenza ngombane, nto leyo enyanzelisa ukwanda ukuya kumazibuko alishumi elinesibini okanye alishumi elinesithandathu. Impendulo eqhelekileyo, i-transformer enkulu kunye neetshaja ezingaphezulu, ingqubana neenyani ezimbini: ukuphuculwa kwe-transformer kubiza i-USD 50,000–200,000 ngamaxesha okukhokela eenyanga ezili-12–18, kwaye izivumelwano zoqhagamshelo lwezixhobo zixoxiswana kabuhlungu. Abaqhubi abakha i-traffic yanamhlanje bathintela ukukhula kwabo; abaqhubi abakha i-traffic yangomso bachitha imali eninzi ngenxa yokungasebenzi.

I-BESS isusa amandla okutshaja kumandla egridi. Ihabhu inokufaka iitshaja ezinamandla aphezulu ngoko nangoko, izisebenzise ekukhutshweni kwebhetri ngexesha lokuphakama, kwaye itsale iprofayili eqinileyo neqinileyo kwigridi. Xa ithrafikhi ikhula, umqhubi wongeza iikhabhathi zebhetri okanye izikhongozeli kunye neemodyuli zamandla - hayi iitransformer. Le yimodeli yokuguquguquka edibana kuyo ii-hubs zeklasi ye-megawatt eYurophu naseMntla Melika, kwaye yingakho umgca wemveliso ye-MIDA ugubungela iikhabhathi, izitishi ezidibeneyo, kunye nezikhongozeli ezakhiwe ngeenxa zonke zeemodyuli zamandla ezifanayo.

Izinto Ezintathu Ezifunekayo, Ibali Elinye Lokukhula

Izisombululo zeBESS zeehub ezinamandla aphezulu ziza ngeendlela ezintathu ezihambelanayo. Ukukhetha phakathi kwazo akusosigqibo sokuba yeyiphi na/okanye isigqibo — iihub ezivuthiweyo zisebenzisa zonke ezintathu:

Ingcamango edibanisayo: yonke into ekwimo ithetha ulwimi olufanayo lwe-EMS kwaye isebenzisa iibhloko zokwakha ezifanayo - ukuguqulwa kwe-AC-DC kwicala elibini, iirakhi zebhetri ezipholileyo ngolwelo, kunye neemodyuli zamandla ze-DC eziguquguqukayo. Umsebenzisi angaqala ngeetshaja ezimbini ze-BESS ezihlanganisiweyo (https://www.midapower.com/integrated-bess-charger/), wongeze [ikhabhinethi yetshaja ye-BESS] (https://www.midapower.com/bess-charger-cabinet/) xa inqwelo-moya ifika, aze afake [isikhongozeli se-2 MWh] (https://www.midapower.com/bess-charger-container/) xa ihabhu ifikelela kwisikali se-megawatt, kunye neqonga elinye lolawulo kunye nesakhono esinye sokulungisa esibekwe kuyo yonke.

Indlela Yokulinganisa: Ukusuka Kwiitshaja Ezine ukuya Kuma-24

Umbuzo osebenzayo wonke umntu osebenza ngebhetri uthi “ingakanani ibhetri, kwaye nini?” Le ndlela yokulinganisa ingezantsi ibonakalise ukuba iyasebenza kwiindawo zokugcina iimoto, kwiindawo zokupaka iimoto, nakwiindawo ekuyiwa kuzo:

1. Yenza umzekelo wejika lomthwalo.Iprofayili yeenyanga ezili-12 zeeseshoni ezilindelekileyo: iiseshoni ngosuku, umyinge wamandla ngeseshoni nganye, kunye nokuqokelelana kwabantu abafikayo. Iwindow ephezulu (ngesiqhelo i-16:00–20:00 okanye emini kwiinqanawa) ichaza iwindow yokukhupha. 2.Yenza ubungakanani bonxibelelwano lwegridi yanamhlanje.Ixabiso legridi lifikelela kuma-60–70% kuphela yemfuno yokutshaja okuphezulu. Ibhetri inika umahluko ngexesha lokuphakama. 3.Yenza ubungakanani bebhetri bulingane nenyathelo lokukhula.Ukonyuka komthamo ngamnye (umz., +200 kWh) kufuneka kugubungele iinyanga ezili-18–24 ezizayo zokukhula komthwalo. Eli lithuba elihle phakathi kokusebenza kakuhle kwemali kunye nokuphindaphinda kokunikezelwa kwemali. 4.Yongeza amandla kwiimodyuli ezikhulayo.Iimodyuli zamandla (eziqhelekileyo ezingama-30–60 kW, ezipholileyo ezingama-40–125 kW) zikhupha itshaja yesikali. Ngenxa yokuba iimodyuli zinokutshintshwa shushu kwiikhabhathi ze-MIDA, ukuphuculwa kwamandla akufuneki zifakelo zetshaja ezintsha. 5.Phinda uvavanye rhoqo ngekota.Idatha yendlela yokuthutha impahla inika isicwangciso sokuqhubeka; izikhongozeli zingongezwa kumjikelo wokuthenga oqhelekileyo xa ukusetyenziswa kudlula umda.

Itheyibhile engezantsi idwelisa amanqanaba ee-hub ezimele ulwakhiwo lwe-BESS:

I-Megawatt Frontier: 960 kW ukuya kwi-2 MWh nangaphezulu

Umbane onzima utyhala ii-hubs ngaphaya kophawu lwe-1 MW, apho ii-dynamics ezimbini zitshintsha ubunjineli: amanqanaba ombane wetshaja ngoku afikelela kwi-600 kW–1.5 MW ngeplagi nganye (i-MCS yeelori), kwaye ulawulo lobushushu luba ngumqobo wokuvala. Kula manqanaba ombane, iintambo ezipholileyo ezingama-500 A+ kunye neemodyuli zombane ezipholileyo ziyimfuneko — ukupholisa umoya akunakuyilahla i-heat density. Ii-MIDA's [iimodyuli zombane ezipholileyo](https://www.midapower.com/liquid-cooled-power-module/) (40–125 kW) kunye ne-1,000 V wide-voltage architectures zixhasa uqwalaselo lweklasi ye-megawatt, kunye ne-[BESS charging stations](https://www.midapower.com/bess-charging-station/) ezifana neyunithi ye-960 kW/2 MWh kunye neenkqubo ze-480 kW/1 MWh ezenzelwe kanye lo msebenzi.

Kwabaqhubi bee-hub, utshintsho lwe-megawatt luqinisa umgaqo wokukhula: isikhongozeli se-2 MWh asiyokhabhathi enkulu, ludidi olwahlukileyo lwe-energy asset eyondla ibhasi ye-DC yehabhu yonke. I-EMS ixazulula phakathi kwesikhongozeli, iikhabhathi, kunye nezithuthi ezixhunyiweyo, iqinisekisa ukuba iindleko ezincinci zokongeza iplagi enye ye-600 kW yimodyuli yamandla kunye nentambo - hayi i-substation.

Izithintelo zeGrid: Xa iBESS ikuphela kwendlela yokwandisa

Uninzi lweendawo ezixabisa kakhulu — izithili zasezidolophini ezixineneyo, iipaki zoshishino, iindawo zeenkonzo zeendlela ezinkulu — zihlala kwiindawo zokutyela ezigcweleyo apho umbane ungenakuqinisekisa amandla ongezelelweyo kangangeminyaka. Kwezi ndawo, iBESS ayilophuculo lwezoqoqosho; bubuchwepheshe obuvumelayo. Indawo ifumana amandla ayo ancitshisiweyo rhoqo, igcina amandla ngexesha lezithuthi eziphantsi (kuquka ubusuku bonke), kwaye inika amandla okutshaja ngaphezulu kakhulu kunomlinganiselo woqhagamshelo lweefestile ezizinzileyo. Abaqhubi benza ngempumelelo i-microgrid yabucala phezu kwenkonzo yegridi evaliweyo.

Le ndlela yokusebenza itshintsha iprofayili yomngcipheko ngendlela ethandwa ngumsebenzisi: akukho kulinda uqhagamshelo, akukho kuqhushumba kwemfuno, kunye nokufikelela okuqinisekisiweyo kubathengi nangona kukho ii-grid peaks. Nangona kunjalo, uyilo kufuneka lubandakanye ukhuseleko oluqinileyo lwe-islanding kunye nee-inverters ezithobela ikhowudi yegridi ukuze i-hub iqhagamshelwe ngokucocekileyo ngexesha leziganeko zombane kwaye iqhagamshelane kwakhona ngokuzenzekelayo - ukuthotyelwa komthetho okuqinisekiswa sisiqinisekiso sengingqi (CE, UL, iikhowudi zegridi zasekuhlaleni).
