Ingxaki Yokutshaja Kweenqanawa: Kutheni Umthamo Wegridi Uhluleka Kuqala

Ilori yombane yeClass 8 enebhetri ye-500–700 kWh idla ngokufuna i-300–500 kWh ngeseshoni nganye ukuze ibuyele emsebenzini. Xa iilori ezintlanu zifika ekupheleni kweshifti, idepho ngequbuliso ifuna i-1.5–2.5 MWh eziswa ngaphakathi kwefestile yeeyure ezine ukuya kwezintandathu. I-transformer eqhelekileyo yesiza—edla ngokuba yi-500 kVA ukuya kwi-1 MVA—ayikwazi ukuxhasa loo mthwalo, kwaye ukuphuculwa koqhagamshelo lwezixhobo kuthabatha iinyanga ezili-12 ukuya kwezingama-24 kwaye kubiza amanani amathandathu kwiimarike ezininzi.

Le yeyona ngxaki iphambili yokufakelwa kombane kwizithuthi: amandla afumaneka kwigridi, kodwa amandla akafumaneki. I-BESS eyenzelwe wena iyawahlulahlula la mabini. Ibhetri itshaja kwigridi ngesantya esizinzileyo nesivumelekileyo (umzekelo, i-250 kW) kwiiyure ezininzi, ize ikhuphe kwi-480 kW, i-960 kW, okanye ngaphezulu xa kufika iilori. Imfuno ephezulu yegridi kwindawo ihlala ihleli ngelixa amandla okutshaja elingana neemfuno zeenqwelo.

Kubaphathi beenqwelo-mafutha, isiphumo esisebenzayo silula: i-BESS isusa isizathu esinye esiqhelekileyo sokuba iiprojekthi zokutshaja iilori zilibaziseke—ukulinda umbane. Isikhululo sokutshaja se-BESS [2 MWh 960 kW] (https://www.midapower.com/2mwh-960kw-bess-charging-station-megawatt-ev-charger-solar-battery-storage-system-product/) sinokuvelisa imveliso ye-megawatt-level evela kuqhagamshelo oluncinci kunobukhulu balo, nto leyo eyenza umbane wedepo ube yiprojekthi yokwakha endaweni yeprojekthi yombane.

I-Anatomy ye-BESS eyenzelwe iinqanawa zeelori

Ihabhu yokutshaja yeBESS yodidi lweflethi ayinabhetri kunye netshaja nje kuphela. Iinkqubo ezingaphantsi kwezi zilandelayo:

1. Ibhloko yokugcina amandla ebhetri— Iiseli ze-LFP (i-lithium iron phosphate) zicwangciswe kwiirakhi, zinobukhulu obuyi-100–500 kWh, kunye nolawulo lobushushu kunye nokubeka iliso kwinqanaba leseli. 2.Iitshaja ezikhawulezayo zeDC— Iiyunithi ezingama-120 kW ukuya kuma-960 kW+, kusetyenziswa izihlanganisi zeCCS1, CCS2, okanye zeMCS, zihlala zineentambo ezipholisiweyo ngolwelo ezilinganiswe kwi-500 A nangaphezulu kwiiseshoni zombane ophezulu eziqhubekayo. 3.I-PCS ejikelezayo (inkqubo yokuguqula amandla)— iguqula igridi ye-AC ibe yi-DC yebhetri kwaye ixhasa ukuhamba kwamandla ombane okukwaziyo ukusebenza nge-V2G apho imigaqo ivumela khona. 4.Inkqubo yolawulo lwamandla kwindawo (i-EMS)— icwangcisa ukutshaja, inyanzelisa imida yemfuno, kwaye iququzelela i-arbitrage, ukucheba okuphezulu, kunye nempendulo yemfuno. 5.I-Telematics kunye ne-OCPP 2.0.1 ngasemva— iqhagamshela iitshaja kwisoftware yolawulo lwedepho yeenqwelo-moya kunye neqonga lelifu lomqhubi.

Into eyenzelwe wena ibalulekile kuba indawo yokugcina iiteksi, iziko lokuhambisa izithuthi lengingqi, kunye nomsebenzi wokulahla imithwalo echwebeni zineendlela ezahlukeneyo zomthwalo. Umsebenzisi wezibuko unokufuna ukuqhuma okufutshane nokunamandla phakathi kokufika kweenqanawa; iziko lokuhambisa izithuthi lifuna ukutshaja ubusuku bonke; izithuthi zokwakha zinokungenelwa kwisikhululo sokutshaja se-BESS esiphathwayo [esingu-418 kWh 240 kW] (https://www.midapower.com/418kwh-240kw-bess-charging-station-battery-storage-mobile-ev-charger-product/) esihamba phakathi kweendawo zomsebenzi.

Ukulinganisa Inkqubo: Ukusuka kwiDuty Cycle ukuya kuMbane weBhetri

Ubungakanani buqala ngedatha, hayi ngeekhathalogu zabathengisi. Le nkqubo inamanyathelo amahlanu:

1. Qokelela i-telemetry— imigama yendlela yokubhala, amandla ngemayile nganye, amaxesha okuphela kweshifti, kunye neeprofayili zamandla etshaja kwiimodeli zelori zokwenyani. 2.Yakha ijika lokufika— bonisa ukuba zingaphi iilori ezifuna umbane ngeyure nganye yosuku. Ukuqokelelana kwamaqela lutshaba lokulayisha ngokutyibilikayo. 3.Chaza ifestile yokuthumela— iiyure apho ilori nganye kufuneka ifikelele kwisimo sokutshaja esijoliswe kuso (ngesiqhelo i-80–100% kwishifti yokuqala).Fumana amandla aphezulu— amandla okutshaja aphezulu ngaxeshanye, aqhuba itshaja kunye novavanyo lwamandla e-BESS. 5.Bala amandla afunekayo— amandla emihla ngemihla, aqhuba amandla ebhetri, kunye nomda woyilo we-15–20% wokonakala kunye nokuphazamiseka kwemozulu ebandayo.

Itheyibhile engezantsi ibonisa iziphumo zobungakanani ezimele iiprofayili ezintathu eziqhelekileyo zeenqwelo-moya:

Umthetho obalulekileyo: i-BESS kufuneka igubungele i-30–50% yamandla emihla ngemihla e-depot, kunye negridi eyondla intsalela ngesantya esingaguqukiyo. Le bhalansi inciphisa iindleko zokujikeleza kwebhetri ngelixa inyusa ukonga kweendleko zemfuno.
