Ukutshaja okuthembekileyo kweBESS kwiindawo zeenkonzo zeendlela ezikude

Impendulo ekhawulezileyo

Iindawo zeenkonzo zeendlela ezikude zezona ndawo zinzima kakhulu ekutshajeni nge-EV: uqhagamshelo lwegridi olubuthathaka okanye olungekhoyo, amaqondo obushushu aphezulu, amaxesha ohambo olude lokulungisa, kunye nabathengi abangayi kuxolela itshaja efileyo. Ukutshaja okuxhaswe yi-BESS kusombulula oku ngokudibanisa amandla okutshaja kumthamo wegridi - ikhabhinethi yetshaja ye-BESS okanye ibhanki yesikhongozeli inika i-120-480 kW yokutshaja kumandla agciniweyo kuqhagamshelo olunokunikezelwa luluntu, kunye nolawulo lobushushu olupholileyo olumanzi ukugcina imveliso elinganisiweyo kwi-45°C+ ehlotyeni kunye ne-20°C ebusika. Ukuthembeka kule ndawo kuyilwe ngendlela, akulindelwanga: iimodyuli zamandla ezitshintshatshintshayo ezishushu, abalawuli be-EMS abangafunekiyo, ukujonga kude, kunye neendawo ezirhangqiweyo ze-IP ziguqula umnxeba wenkonzo weentsuku ezi-3 ube kukutshintshana kwemodyuli yemizuzu eli-15. Isiphumo sokusebenza kwiindawo ezikude eziyilwe kakuhle kukufumaneka kwetshaja ye-97-99%, nto leyo eguqula indawo yokuma yendlela ibe yindawo yengeniso ethembekileyo.

Izinto ezibalulekileyo ekufuneka ziqwalaselwe

• I-BESS ivumela iindawo ezikude ukuba zikwazi ukutshaja ngamandla aphezulu kwiinethiwekhi zegridi ezibuthathaka okanye ezingekhoyo, isusa isithinteli esiphambili sokufakwa.
• Ukuthembeka kwenziwa ngokusebenzisa uhlengahlengiso: iimodyuli ezitshintshatshintshayo, iibhasi ze-DC ezihlukanisiweyo, abalawuli be-EMS abangafunekiyo, kunye nokuxilongwa okukude.
• Ukupholisa ulwelo kunye neendawo ezivalekileyo ze-IP65+ akunakuxoxiswana ngazo kwiindawo ezikude apho iindawo ezikude kunye nothuli/umkhenkce zilawula ukusebenza kwemihla ngemihla.
• Uyilo lweBESS oluyimodyuli luguqula ulondolozo ukusuka kuhambo lweentsuku ezi-3 ukuya kutshintsho lwezixhobo lwemizuzu eli-15 yingcali yendawo.
• Ixesha lokusebenza, hayi amandla entloko, yimilinganiselo yengeniso: ukufumaneka kwe-97–99% kudlula ukufakelwa okukhulu kodwa okubuthathaka.

Ingxaki yeNdlela ekude: Kutheni iGrid Power iyindawo engafanelekanga yokuqala

Iindawo zenkonzo yeendlela zikwiindawo ezichanekileyo apho amandla egridi ebuthathaka khona: iikhilomitha ukusuka kwizikhululo zepetroli, kwii-feeders ezinobukhulu bomthwalo wokukhanyisa wesikhululo sepetroli, ezihlala zikhonzwa ziintambo ezidala eziphezulu. Indlela eqhelekileyo yokusasazwa - faka isicelo sokuphuculwa kwetransformer, linda iinyanga ezili-12-24, uhlawule i-USD eyi-100,000-300,000 yokwakha - ayiqhelekanga ngokwezoqoqosho kwindawo apho izithuthi zayo zinokukhula ngendlela engalindelekanga. Okubi nangakumbi, kwiindawo ezininzi zeendlela ezinkulu zasemaphandleni, umbane awunakubonelela ngomthamo nangaliphi na ixabiso ngaphakathi kwexesha elifanelekileyo.

I-BESS isusa igridi kwindlela ebalulekileyo. Indawo itsala nawuphi na umthamo okhoyo - rhoqo i-100-200 kVA - rhoqo, igcina amandla ubusuku bonke nangexesha elingengomsebenzi omkhulu, kwaye inika amandla okutshaja angama-120-480 kW kwiiqhushumbisi ezivela kwibhetri. Igridi iba yitshaja ethambileyo yebhetri; ibhetri iba sisakhiwo sokutshaja. Olu luyilo oluchanekileyo lomgca we-MIDA [we-BESS charging station](https://www.midapower.com/bess-charging-station/) kunye neeyunithi ze-BESS eziphathwayo/zohlangulo ezibonakaliswe ekusetyenzisweni okungxamisekileyo, apho ingqiqo efanayo "yokugcina, emva koko ukuhambisa kwiiqhushumbisi" isebenza kwiindawo ezingenagridi konke konke.

Kutheni iBESS ingumniki-mandla - kwaye kuthetha ukuthini ukuthembeka apha

Kwindawo ekude, ukuthembeka kunentsingiselo ethile: itshaja inika amandla alinganisiweyo xa umthengi efaka, nangaliphi na ixesha lonyaka, ngexesha eliphakathi lokulungisa elilinganiswa ngeeyure, kungekhona iintsuku. Iileya ezintathu zoyilo zivelisa loo mphumo:

1. Ukufumaneka kwamandla

Itshaja ekude yegridi kuphela iyasilela ngalo lonke ixesha i-feeder yendawo isiya - kwaye ii-feeder ezikude ziyasilela rhoqo. Indawo ye-BESS iyasilela kuphela xa ibhetri ingenanto, into ethintelwa yi-EMS ngokuyivala kumgangatho otshajayo kwaye ifake i-grid okanye i-solar nanini na xa ikhona. [Iitshaja ze-BESS zeMobile](https://www.midapower.com/mobile-bess-charger/) kunye neenkqubo ezikwizikhongozeli ziyandisa le ngqiqo ngakumbi: zinokufakwa kwiilori ukuze zinike amandla okwethutyana ngexesha lokunyuka kwemfuno okanye iifestile zokulungisa igridi.

2. Ukuqina kobushushu

Iindawo ezikude zenkonzo zilapho amaqondo obushushu aphezulu kakhulu kwaye umoya uphantsi kakhulu. Iibhetri kunye ne-elektroniki zamandla kufuneka zigcine i-flowput elinganisiweyo kwi-45°C ngaphandle kokuphazamiseka, kwaye ziphile ubusuku obungama-20°C ngaphandle kokuncipha komthamo. Iinkqubo ezipholisiweyo ngolwelo - iirakhi zebhetri, iimodyuli zamandla, kunye neentambo ezingama-500 A+ - ziyala ubushushu kwaye zifudumale kwangaphambili ukusuka kwisangqa esinye kwiindawo ezibandayo. Ezinye iindlela ezipholisiweyo ngomoya zilahlekelwa yi-10–25% ye-flowput kanye xa indawo ixakekile.

3. Inkonzo enokulungiselelwa xa umgama

Ukufowunela kwindawo ekude kubiza usuku lonke lokuhamba ngaphambi kokuba ingcali ichukumise isixhobo. Impendulo yoyilo yi-modularity: iimodyuli zamandla ezitshintshwayo ezishushu, iirakhi zebhetri ezixhunywayo, kunye neeyunithi zokupholisa ezitshintshwayo zomgca zithetha ukuba umakhi wengingqi onoqeqesho olusisiseko unokwenza ukulungiswa okuya kufuna injineli yefektri. Iinkqubo ze-MIDA [BESS charger cabinet](https://www.midapower.com/bess-charger-cabinet/) kunye neenkqubo ze-split-architecture zakhiwe ngolu hlobo - iyunithi etshintshwayo yimodyuli, hayi isikhululo sonke.

Uyilo Lokuthembeka Kwiimeko Ezinzima

Itheyibhile engezantsi ibonisa iindlela zokungaphumeleli ezilawula imisebenzi yeendlela ezikude ukuya kwiikhawuntara zazo zobunjineli:

Iipateni ezimbini zifanele ukugxininiswa. Okokuqala, ukuphinda-phinda kubekwe ngokwamaleko: indawo engama-480 kW kufuneka yahlulwe kwiikhabhathi ezininzi okanye kwiikhonteyina ukuze ukusilela kube kanye konakalise umthamo ngaphandle kokuwubeka u-zero. Okwesibini, i-telemetry luphawu lokuthembeka, hayi ideshibhodi yokunethezeka - ukujonga kude kuguqula "itshaja ibikwe ifile, thumela umntu" ibe "imodyuli B-2 kwikhabhinethi 3 ibonisa impazamo yefeni, thumela imodyuli enye yokutshintsha," nto leyo umahluko phakathi kosuku kunye neveki yexesha lokungasebenzi.

Icebo Lokugcina Nokusebenza: Imodeli Yokusebenza ye-97–99%

Iindawo ezikude ezinokuthenjwa zisebenza ngemodeli yokusebenza, hayi iwaranti. Iindlela ezahlula ukufumaneka kwe-90% kwi-98%:

1. Ukubeka esweni okukude kuqala.Ikhabhinethi nganye ithumela i-state of charge, amaqondo obushushu eeseli, uxinzelelo lwe-loop yokupholisa, ukubalwa kwemijikelo, kunye neekhowudi zokusilela kwi-EMS yelifu. Izilumkiso ziqala ngaphambi kokuba zingasebenzi - umkhwa wokunyuka kwamaqondo obushushu okupholisa unokwenzeka kwiiveki ngaphambi komsitho wohambo. 2.Izixhobo zokuncedisa ezibekwe kwangaphambili.Ingingqi nganye igcina isitokhwe esincinci seenxalenye ezintathu ezisoloko zingasebenzi kakuhle: iimodyuli zamandla, iiyunithi zokupholisa, kunye neebhodi zolawulo. Amaxabiso angaphantsi kwendawo adlula imithwalo yongxamiseko ngalo lonke ixesha. 3.Inethiwekhi yenkonzo yamaqabane asekuhlaleni.Izixhobo zemodyuli zivumela ukuqeqesha umenzi wekontraka wengingqi ngosuku. I-SLA yenkonzo iba “yimodyuli yokutshintsha kwiiyure ezingama-24” endaweni yokuba “unjineli wefektri ufike kwiintsuku ezi-5.” 4.Iifestile zokulungisa zexesha elithile.Ukutyelela kabini okucwangcisiweyo ngonyaka (ngaphambi kwehlobo, ngaphambi kobusika) kuqinisekisa ii-loops zokupholisa, i-insulation, kunye noqhagamshelo. Ukutyelela okungacwangciswanga kwiindawo ezikude kudla ngokubiza i-3–10× ngokutyelela okucwangcisiweyo. 5.Ukuthunyelwa okuqaphela ubungakanani.I-EMS igcina umgangatho ofanelekileyo (umz., i-15–20%) ugciniwe xa kukho iimeko ezingxamisekileyo kunye nokungasebenzi kakuhle kwegridi, ukuze indawo ikwazi ukuhlawula ubuncinane inxalenye yentlawulo nokuba sele iphelile.

Ingqiqo yezemali ayicacanga: iseshoni yokutshaja yendlela engaphumeleliyo ngenxa yokuba itshaja ihlawulwe ibiza umqhubi ingeniso yeseshoni, inceba yomthengi, kwaye - kwiikhontrakthi zesivumelwano - isohlwayo ngokuchasene nee-KPI zokufumaneka. Ukufumaneka kwe-97–99%, okuqhubekekayo ngamaxesha onyaka, yiyo eguqula indawo ye-BESS ekude ibe yimpahla enokubhatalwa.
