Kutheni i-BESS yeModular inikezela ngokuguquguquka okungafaniyo kwabaqhubi

Impendulo ekhawulezileyo:Inkqubo yokugcina amandla ebhetri yemodyuli (BESS) yakhiwe ngamandla aqhelekileyo, anokutshintshwa ngokuzimeleyo kunye neebhloko zebhetri endaweni yokuba ibe yiyunithi enye ye-monolithic, evumela abaqhubi ukuba balinganise umthamo ngamanyathelo anokuqikelelwa — umzekelo ukusuka kwiyunithi ye-120 kWh/60 kW ukuya kwisikhululo se-625 kWh/400 kW — ngokongeza iimodyuli ezifanayo. I-Modularity inika izibonelelo ezine zokusebenza ezingenakulinganiswa noyilo lwe-monolithic: inkcitho yemali-mboleko njengoko ukhula, ukugcinwa kwe-hot-swap okunciphisa ixesha lokungasebenzi ukusuka kwiintsuku ukuya kwiiyure, ukungasebenzi kwe-N+1 okugcina indawo ikwi-intanethi ngexesha lokusilela kwezixhobo, kunye nokuguquguquka kokusasazwa kwiifomathi ezisisigxina, eziphathwayo, kunye nezihlanganisiweyo zelanga kusetyenziswa izixhobo ezifanayo eziphambili. Kubaqhubi beenqwelo-moya kunye neendawo zokutshaja, uyilo lwe-modular luguqula indawo yokugcina ukusuka kutyalo-mali olusisigxina, olunobungozi lube yi-asethi yokusebenza enokwandiswa ngokukhawuleza, iindleko eziphantsi zobunini, kunye nendlela ecacileyo yokwandiswa kwexesha elizayo.

Izinto ezibalulekileyo ekufuneka uziqwalasele:

• I-BESS esetyenziswayo inciphisa imali yokuqala nge-40–60% xa ithelekiswa nenkqubo enkulu kakhulu ye-monolithic, kuba amandla ombane ongezelelweyo kuphela xa ukusetyenziswa kwawo kuqinisekisa oko.
• Iibhloko zebhetri kunye nombane ezisemgangathweni zivumela ukutshintshwa kwe-hot-swap, ukunciphisa ixesha eliphakathi lokulungisa ukusuka kwiintsuku ukuya kwiiyure kunye nokunciphisa uluhlu lwezinto ezisetyenzisiweyo.
• Ukungasebenzi kakuhle kwemodyuli ye-N+1 kuthetha ukuba imodyuli enye yamandla okanye ibhetri engasebenziyo inciphisa amandla kancinci endaweni yokuba yonke indawo ingasebenzi.
• Iibhloko ezifanayo zemodyuli ziqala kwi-60 kW/120 kWh kwiindawo zokubeka udonga ukuya kwizikhululo zikaloliwe ezingama-400 kW/625 kWh — kwaye zihamba phakathi kweendawo zokugcina izinto ezisisigxina, eziphathwayo, kunye nezo zisetyenziswa yilanga.
• Abaqhubi abakhetha uyilo lweemodyuli banciphisa amaxesha okukhokela iprojekthi kwaye benze lula ukuthengwa, uqeqesho, kunye nolawulo lwewaranti kwiindawo ezininzi.

Umgibe weMonolithic: Kutheni ibhetri enye enkulu ilimaza abaqhubi

Umqhubi wezothutho wayefuna amandla okutshaja angama-300 kW, waza, elandela icebiso lomcebisi, wathenga inkqubo yokugcina enye edibeneyo enobukhulu obungama-480 kWh ukugubungela "ukukhula kwexesha elizayo." Emva kweenyanga ezilishumi elinesibhozo, ukusetyenziswa kwafikelela kwi-40% kuphela yamandla ebhetri: iinqwelo zazikhule kancinci kunokuba bekulindelwe, incopho yendawo yayiyi-220 kW, kwaye ibhetri enkulu yayijikeleza kancinci - indlela yokusebenza engenanzuzo yokugcina. Okubi nangakumbi, xa i-inverter yodwa ingaphumeleli, yonke indawo yokutshaja yayimnyama kangangeentsuku ezintlanu ngelixa enye ithunyelwa ivela phesheya.

Indlela ye-monolithic ayiphumeleli kubasebenzi kwiindlela ezintathu: ixesha lemali (ukuhlawula namhlanje umthamo osetyenzisiweyo kwiminyaka emithathu), i-failure blast radius (amanqaku omnye okusilela athabatha yonke impahla), kunye nokuguquguquka (uyilo oluzinzileyo alunakufuduka xa iindlela zeenqwelo-moya okanye uyilo lwesiza lutshintsha). Ezi ziindlela zokusilela ezisuswayo kuyilo lwemodyuli, yiyo loo nto i-modular BESS ibe luyilo oluqhelekileyo kwicandelo lezorhwebo nelemizi-mveliso, kwaye kutheni phantse yonke i-reference architecture epapashwe ngabaqhubi begridi kunye nabaqokeleli be-aggregators ithatha iibhloko zokwakha zemodyuli, ezisemgangathweni.

Oko Kuthethwa YiModularity KwiBESS

Ukuguquguquka kokutshaja kwe-EV okudityanisiweyo yi-BESS kusebenza kumanqanaba amabini: indlela yamandla kunye nendlela yamandla. Indlela yamandla ineeyunithi zokuguqula amandla ezisemgangathweni ezijikelezileyo — ze-MIDA, iimodyuli ezikudidi lwe-[20–40 kW](https://www.midapower.com/ev-charging-power-module) eziguqula igridi ye-AC ibe yi-DC yebhetri kunye netshaja, kunye neendidi ezipholileyo ezingamanzi ukuya kuthi ga kwi-125 kW kwizicelo zamandla aphezulu. Indlela yamandla ineebhloko zebhetri ezisemgangathweni, eziqhelekileyo ziyi-20–100 kWh nganye, ezakhiwe ngeeseli ze-LFP eziqinisekisiweyo ezine-BMS edibeneyo kunye nolawulo lobushushu.

Ibhloko nganye izimele ngokwayo: i-BMS yayo, uqhagamshelo lwayo lokupholisa, kunye neendawo ezisemgangathweni zombane kunye noomatshini. Iibhloko zidityaniswe ngochungechunge kwaye zihambelana ukuze zifikelele kwi-voltage kunye nomthamo ekujoliswe kuwo. Yile nto yahlula i-modularity yokwenyani kwi-component nje: nayiphi na ibhloko inokutshintshwa, ilungiswe, okanye itshintshwe ngaphandle kokuchukumisa ezinye, kwaye umlawuli wenkqubo uhlengahlengisa ngokuzenzekelayo kwinani elitsha leebhloko. Umsebenzisi olinganisa ukusuka kwi-240 kWh ukuya kwi-482 kWh wongeza nje enye ibhloko esemgangathweni, ayidibanise nebhasi ye-DC, kwaye avumele i-EMS ukuba iphinde iphucule - akukho luyilo lutsha, akukho mfuneko yokuphinda indawo isebenze, akukho xesha lokuphumla elongezelelweyo.

I-Modular vs. iMonolithic: Uthelekiso olusecaleni

Itheyibhile yokuthelekisa ibonisa oko abaqhubi baxela kona xa besenza: iinkqubo ze-monolithic ziphumelela kuphela apho iprofayili yomthwalo wesiza ingaguquki ngokupheleleyo ubomi bempahla epheleleyo — imeko engaqhelekanga kwimarike yokutshaja apho inani lezithuthi, amanqanaba ombane, kunye nezakhiwo zerhafu zonke zitshintsha ngaphakathi kweminyaka emihlanu.

Ukwandisa Ubungakanani Ngaphandle Kokwakha Okugqithisileyo: Ubungakanani Basekunene NgeeBhloko Eziqhelekileyo

Ubungakanani obuchanekileyo sesona sigqibo sikhulu sezemali kwiprojekthi yokugcina, kwaye i-modularity yenza ukuba iguqulwe. Umgaqo wobunjineli wokutshaja kwe-EV kukuba ubungakanani bokugcina bube yi-0.5–1× amandla okutshaja aphezulu kwindawo nganye kwiiyure ze-kilowatt: indawo eyi-120 kW idla ngokufuna i-120–240 kWh; indawo eyi-320 kW ifuna i-240–480 kWh. [Usapho lwemveliso yemodyuli](https://www.midapower.com/energy-storage-charging-station) ivumela umqhubi ukuba athenge umda osezantsi kuqala aze andise xa idatha yokusetyenziswa iqinisekisa oko.

Zonke ii-configurations zabelana ngosapho lwee-modules ezifanayo, ngoko ke umqhubi oqhuba ii-site ezintlanu kwii-scales ezahlukeneyo ugcina i-module enye yamandla eseleyo kunye ne-battery block enye eseleyo kwinethiwekhi yonke. Ukwandiswa phakathi kwee-configurations kukuphinda kumiselwe kwinqanaba lesiza - ukongeza ii-blocks kunye nokulinganisa kwakhona i-EMS - akusiyo into entsha ethengwayo.

Icebo Lokugcinwa, Ukuphinda Kusetyenziswe Izinto Ezintsha, kunye Nezicwangciso Zokugcina Izinto Ezingasetyenziswanga

Ukufumaneka kulapho i-modularity ifumana khona ukugcinwa kwayo ngokusebenza. Kwisakhiwo samandla se-modular, isilawuli sesitishi sisebenzisa i-N+1 redundancy: ulungiselelo lwe-6×40 kW power block olukhonza umthwalo we-240 kW lunyamezela ukusilela kwayo nayiphi na imodyuli enye ngaphandle kokunciphisa umthamo wendawo, kwaye ukusilela kwesibini kunciphisa umthamo ngokulinganayo. Iibhloko zebhetri zisebenza ngendlela efanayo - i-BMS iyahlula ibhloko engasebenziyo, kwaye iibhloko eziseleyo ziyaqhubeka nokusebenza kwibhasi ye-DC.

Ukulungiswa kwe-Hot-swap emva koko kuguqula loo mvalelo ube kukubuyiselwa ngokukhawuleza. Ngenxa yokuba iibhloko zineendawo ezihambelanayo, ingcali itshintsha iyunithi engasebenziyo ngaphantsi kweyure isebenzisa izixhobo zesandla, ngokuchasene nokulungiswa kwefektri yeentsuku ezininzi kwiyunithi ye-monolithic edibeneyo. Oku kunciphisa ixesha eliphakathi lokulungisa ukusuka kwiintsuku ukuya kwiiyure, kuphakamisa iziqinisekiso zokufumaneka kweenqwelo-mafutha, kwaye kunciphisa uluhlu lwezinto ezingasetyenziswayo lube yiseti encinci yeeyunithi ezitshintshanayo ezabelwana ngazo kwinethiwekhi. Kubaqhubi abanezivumelwano zenqanaba lenkonzo yokutshaja kwiindlela ezinkulu - apho iyure nganye ngaphandle kweintanethi ilahlekelwa yingeniso kwaye ilahleko yetrasti yomqhubi - lo ngumahluko phakathi kwempahla elungisekayo kunye noxanduva.

Ukuguquguquka kokusetyenziswa: Uyilo olunye, iifomathi ezininzi

I-Modularity ikwahlukanisa izixhobo zamandla kwifomathi yazo ebonakalayo. Ezi bhetri kunye neebhloko zamandla ezifanayo zifakwa kwiifreyimu ezintathu: iikhabhathi ezime phantsi kwiindawo ezisisigxina, iiskidi ezihambayo zokusetyenziswa okwethutyana okanye okungxamisekileyo, kunye nezikhongozeli ezidityaniswe nelanga apho igalelo le-PV londla khona ibhasi ye-DC ngqo.

Olu guqulelo lwefomathi luvumela abaqhubi ukuba baphinde basebenzise iiasethi njengoko iimeko zoshishino zitshintsha. Iyunithi yokugcina ephathwayo ye-200 kWh esetyenziselwa ukugubungela ixesha leziganeko zasehlotyeni iba yindawo yokugcina izinto esisigxina kunyaka olandelayo; isikhululo esisuswa kukulungiswa kwakhona kwendlela sifudukela kwindawo entsha endaweni yokuba sicinywe. Uqwalaselo oludityaniswe nelanga — njengetshaja ye-MIDA ye-200 kWh/120 kW yeselula ye-EV ene-MPPT solar input — ivumela iibhloko ezifanayo zemodyuli ukuba zikhonze iindawo ezinonxibelelwano lwegridi olubuthathaka okanye olungekhoyo, nto leyo eguqula ukuthenga indawo yokugcina ibe yindlela yokuvumela ukuzimela kwegridi.

Indlela yokukhetha uyilo oluchanekileyo lweModular

Ukukhetha i-BESS yemodyuli yokutshaja kwe-EV kunciphisa ukuya kwizigqibo ezintandathu, ngokulandelelana kwazo:

1. Chaza umgangatho kunye nophahla lweenyanga ezingama-24.Thenga indawo yokugcina umgangatho; cwangcisa izongezo zeebhloko zesilingi. 2.Yenza ubungakanani bebhloko enye bube semgangathweni kuyo yonke inethiwekhiukuze kubekho ukutshintshwa okukhulu kwezinto ezingasetyenziswayo kunye noqeqesho. 3.Qinisekisa ukuziphatha kwe-hot-swap kunye ne-N+1 kuyilo lwenkqubo— qinisekisa ukuba isilawuli siyalingana ngokuzenzekelayo xa iibhloko zongezwa okanye zisusiwe. 4.Qinisekisa ukuba usapho lwemodyuli yamandla luhambelana namanqanaba ombane wetshajangoko ke ibhasi yeDC inceda zombini iibhetri kunye nezithuthi ngokufanelekileyo (92–95% ukuya nokubuya).Jonga inkxaso yeprotocol (OCPP, ISO 15118, Modbus) kwiyunithi yesiseko, kuba imodyuli yehardware kufuneka ifikelele kwi-software configuration. 6.Khetha umboneleli onosapho lwemodyuli olufikelela kuluhlu olujoliswe kulo— ukusuka ekubekweni eludongeni ukuya kwisikali sendlela enkulu — ngoko ke ukukhula akuze kunyanzele umthengisi ukuba atshintshe.

I-Modularity ayisiyonto ibalulekileyo; licebo lokusebenza. Iguqula indawo yokugcina izinto ukusuka kwindawo yokungcakaza esisigxina, enkulu kakhulu ibe yipotifoliyo yeebhloko ezisemgangathweni ezikhula ngobungqina, zisilele kakuhle, kwaye zihambe apho ishishini liya khona. Kubaqhubi abacwangcisa iinethiwekhi zokutshaja zeminyaka emihlanu kwimarike ehamba ngokukhawuleza, leyo yinkcazo yokuguquguquka - kwaye isizathu sokuba i-BESS yemodyuli ibe yinto engaqhelekanga kwishishini.
