Inkinga Yokushaja Kwezikebhe: Kungani Amandla Egridi Ehluleka Kuqala

Iloli kagesi le-Class 8 elinebhethri elingu-500–700 kWh livame ukudinga i-300–500 kWh ngeseshini ngayinye ukuze libuyele emsebenzini. Lapho amaloli amahlanu efika ekupheleni kweshifti, idepho ngokuzumayo idinga i-1.5–2.5 MWh elethwa ngaphakathi kwefasitela lamahora amane kuya kwayisithupha. I-transformer evamile yesayithi—ngokuvamile i-500 kVA kuya ku-1 MVA—ayikwazi ukusekela lowo mthwalo, futhi ukuthuthukiswa kokuxhumeka kwezinsiza kusebenza kuthatha izinyanga ezingu-12 kuya kwezingu-24 futhi kubiza izibalo eziyisithupha ezimakethe eziningi.

Lena yinkinga eyinhloko yokufakwa kukagesi ezinqoleni: amandla ayatholakala kugridi, kodwa amandla awatholakali. I-BESS eklanyelwe kahle ihlukanisa lokhu kokubili. Ibhethri lishaja kusuka kugridi ngesivinini esizinzile nesivunyelwe (isibonelo, 250 kW) emahoreni amaningana, bese likhipha ku-480 kW, 960 kW, noma ngaphezulu lapho amaloli efika. Isidingo segridi esiphezulu sendawo sihlala siqinile kuyilapho amandla okushaja elinganiswa nezidingo zemikhumbi.

Kubaphathi bezimoto, umphumela osebenzayo ulula: I-BESS isusa isizathu esisodwa esivame kakhulu sokubambezeleka kwamaphrojekthi okushaja amaloli—ukulinda ugesi. Isiteshi sokushaja se-BESS [2 MWh 960 kW] (https://www.midapower.com/2mwh-960kw-bess-charging-station-megawatt-ev-charger-solar-battery-storage-system-product/) singaletha umkhiqizo wezinga le-megawatt kusuka ekuxhumaneni okuncane kakhulu kobukhulu bawo, okwenza ugesi wedepho ube yiphrojekthi yokwakha kunokuba yiphrojekthi yogesi.

Ukwakheka Kwe-BESS Eyenzelwe Amabutho Amaloli

Ihabhu yokushaja ye-BESS esezingeni le-fleet iqukethe okungaphezu kwebhethri kanye neshaja. Izinhlelo ezincane ezibalulekile yilezi:

1. Ibhulokhi yokugcina amandla ebhethri— Amaseli e-LFP (i-lithium iron phosphate) ahlelwe ngama-rack, alinganiswe ngo-100–500 kWh, ngokuphathwa kokushisa kanye nokuqapha izinga lamaseli. 2.Amashaja asheshayo e-DC— amayunithi angu-120 kW kuya ku-960 kW+, kusetshenziswa izixhumi ze-CCS1, CCS2, noma i-MCS, ngokuvamile ezinezintambo ezipholile ngoketshezi ezilinganiselwe ku-500 A nangaphezulu ukuze kuqhutshekwe nezikhathi zamandla aphezulu. 3.Ama-PCS aqondiswe kabili (uhlelo lokuguqula amandla)— iguqula i-grid AC ibe yi-DC yebhethri futhi isekela ukugeleza kwamandla okusebenza kwe-V2G lapho imithetho ivumela khona. 4.Uhlelo lokuphathwa kwamandla esayithi (i-EMS)— ihlela ukushaja, iphoqelela imikhawulo yesidingo, futhi ihlele i-arbitrage, ukushefa okuphezulu, kanye nempendulo yesidingo. 5.I-Telematics kanye ne-OCPP 2.0.1 back end— ixhuma amashaja kusofthiwe yokuphatha idepho yemikhumbi kanye nepulatifomu yamafu yomqhubi.

Isici esiklanyelwe sona sibalulekile ngoba idepho yamatekisi, isikhungo sokusabalalisa sesifunda, kanye nokusebenza kokudonsa imithwalo echwebeni kunezindlela zomthwalo ezihluke ngokuphelele. Umqhubi wechweba angadinga ukuqhuma okufushane, okukhulu phakathi kokufika kwemikhumbi; isikhungo sokusabalalisa sidinga ukushaja okuqhubekayo ebusuku; imikhumbi yokwakha ingazuza esiteshini sokushaja se-BESS esihambayo [esingu-418 kWh esingu-240 kW] (https://www.midapower.com/418kwh-240kw-bess-charging-station-battery-storage-mobile-ev-charger-product/) esihamba phakathi kwezindawo zomsebenzi.

Ukulinganisa Uhlelo: Kusukela Kumjikelezo Womsebenzi Kuya Kumandla Ebhethri

Usayizi uqala ngedatha, hhayi ngamakhathalogi abathengisi. Inqubo inezinyathelo ezinhlanu:

1. Qoqa i-telemetry— amabanga omzila welogi, amandla ngemayela, izikhathi zokuphela kweshifti, kanye namaphrofayili wamandla okushaja amamodeli eloli langempela. 2.Yakha ijika lokufika— bhala imephu yokuthi mangaki amaloli adinga ugesi ngehora ngalinye losuku. Ukuhlanganisa amaqoqo kuyisitha sokulayisha okuphansi. 3.Chaza iwindi lokuthumela— amahora lapho iloli ngalinye kufanele lifinyelele khona isimo sokushaja esiqondiwe (ngokuvamile u-80–100% weshifti yokuqala).Thola amandla aphezulu— amandla okushaja aphezulu ngesikhathi esisodwa, okushayela ishaja kanye nezilinganiso zamandla e-BESS. 5.Bala amandla adingekayo— amandla aphuma nsuku zonke, okuqhuba amandla ebhethri, kanye nomkhawulo womklamo ongu-15–20% wokuwohloka kanye nokuphazamiseka kwesimo sezulu esibandayo.

Ithebula elingezansi libonisa imiphumela yokulinganisa emele amaphrofayili amathathu avamile emikhumbi:

Umthetho owusizo: i-BESS kufanele imboze u-30-50% wamandla ansuku zonke e-depot, kanti igridi yondla okusele ngesilinganiso esifanayo. Le bhalansi inciphisa izindleko zokujikeleza kwebhethri ngenkathi ikhulisa ukonga kwezindleko zokufunwa.

Ukwakhiwa Okuhlanganisiwe Okuneziqukathi
