Ukujonga Ikamva le-Electromobility: Isikhokelo esipheleleyo soBugcisa kunye noRhwebo sokuthelekisa iitshaja ezikhawulezayo zeLevel 2 AC kunye neLevel 3 DC zeZiseko eziKhululekileyo, ukuHlanganisa iGrid, kunye ne-ROI ephezulu

Isahluko 1: Intshayelelo: Inguqu ye-EV kunye nendima ebalulekileyo yeziseko zophuhliso zokutshaja

Utshintsho lwehlabathi oluya ekuhambeni kombane alusekho nje umkhwa ongaphandle; lutshintsho olubalulekileyo kwindlela yokuthutha. Njengoko amazwe ezibophelela kwiinjongo zokususa iigesi eziyingozi kwaye abavelisi beemoto bejika yonke imigca yabo yemveliso ukuya kwizithuthi zombane zebhetri (ii-BEV), ingqwalasela itshintshile ukusuka kwizithuthi ngokwazo ukuya kwiziseko ezizixhasayo. Impumelelo yolu tshintsho ixhomekeke kwinethiwekhi yokutshaja eqinileyo, ethembekileyo, necwangciswe ngobuchule.

Eyona nto iphambili kwesi sicwangciso seziseko zophuhliso kukhetho olubalulekileyo: Ukutshaja kwe-AC yeNqanaba lesi-2 (L2) xa kuthelekiswa nokutshaja kwe-AC yeNqanaba lesi-3 (L3). Nangona zombini zisebenza injongo enye yokugqibela—ukugcwalisa ibhetri yesithuthi—zimele iindlela zobuchwepheshe ezahlukeneyo, iiprofayili zotyalo-mali, kunye nefilosofi yokusebenza. Kubaphuhlisi bezorhwebo, abacwangcisi bakamasipala, kunye nabaphathi beenqwelo-mafutha, ukuqonda umahluko phakathi kwezi zigaba zimbini akuyomfuneko yobugcisa kuphela kodwa yimfuneko yesicwangciso.

Ukutshaja kwenqanaba lesi-2, okusebenza ngombane otshintshanayo (AC), kube ngumqolo “wokutshaja indawo oya kuyo.” Sisisombululo esifumaneka emakhayeni, kwiindawo zokusebenza, kwiihotele nakwiindawo zokuthenga—iindawo apho izithuthi zihlala zingashukumi iiyure ezininzi. Ngokwahlukileyo koko, iLevel 3 DC Fast Charging (DCFC) sisisombululo se-octane ephezulu “sokutshaja endleleni.” Ngokudlula kwitshaja yesithuthi esingaphakathi kwaye sihambise umsinga othe ngqo we-voltage ephezulu (DC) ngqo kwibhetri, i-DCFC ivumela ukuhamba umgama omde kunye nokujikeleza ngokukhawuleza kwiinqanawa zorhwebo.

Nangona kunjalo, ukhetho phakathi kwe-L2 kunye ne-L3 alufane lube yi-binary. Iinethiwekhi zokutshaja ezisebenzayo zineenqanaba ezininzi, nto leyo enika amandla okusebenzisa i-L2 kwiimeko zokuhlala ixesha elide kunye nesantya se-L3 kwiimfuno eziphezulu zokukhupha. Eli nqaku libonelela ngohlalutyo olupheleleyo lobuchwephesha nolwezorhwebo lwamanqanaba omabini, libonelela ngesakhelo sokwenza izigqibo kwabo banikwe umsebenzi wokwakha imithambo yombane yezixeko zethu ezizayo.

Isahluko 2: Iziseko zobuGcisa: Ukuqonda iindlela zokutshaja ze-AC (iNqanaba lesi-2) vs. DC (iNqanaba lesi-3)

Ukuze umntu aqonde umahluko phakathi kwe-L2 kunye ne-L3, kufuneka aqale aqonde ifiziksi esisiseko yendlela umbane ohamba ngayo ukusuka kwigridi ukuya kwibhetri ye-EV.

Indima ye-Onboard Charger (OBC)

Zonke iibhetri zigcina amandla njengeDirect Current (DC). Nangona kunjalo, igridi yombane isasaza amandla njengeAlternating Current (AC). Ke ngoko, inkqubo yokuguqula kufuneka yenzeke. KwiLevel 1 kunye neLevel 2 yokutshaja, olu tshintsho lwenzekangaphakathiimoto. I-EV ixhotyiswe ngecandelo elibizwa ngokuba yi-Onboard Charger (OBC). I-OBC ithatha umbane we-AC kwisikhululo sokutshaja, iwulungise ube yi-DC, ize ilawule ukuhamba kombane ukuya kwiiseli zebhetri.

Umlinganiselo wokutshaja kwe-L2 awusoloko ukho kwisikhululo (EVSE) ngokwaso, kodwa ngumthamo we-OBC yesithuthi. Uninzi lwee-EV zanamhlanje zine-OBC ezilinganiswe phakathi kwe-7 kW kunye ne-11 kW, ezinye iimodeli zobunewunewu okanye ukusebenza zifikelela kwi-19.2 kW okanye i-22 kW. Nokuba isikhululo se-L2 sinokubonelela ngamandla angakanani, isantya sokutshaja sinqunyelwe koko izixhobo zangaphakathi zesithuthi zinokukuphatha.

Ukudlula iBottle-Neck: Ukutshaja okukhawulezayo kweDC

Ukutshaja okukhawulezileyo kwe-DC yeNqanaba lesi-3 kutshintsha uyilo. Uguqulelo lwe-AC ukuya kwi-DC luyasuswangaphandleIsithuthi saza safakwa kwisikhululo sokutshaja ngokwaso. Ezi zikhululo ziikhabhathi ezinkulu ze-elektroniki ezithatha i-AC ene-voltage ephezulu kwigridi, ziyiguqule ibe yi-DC ene-voltage ephezulu (ngesiqhelo yi-400V okanye i-800V), kwaye ziyifake ngqo kwibhetri.

Ngenxa yokuba esi sikhululo sinxibelelana ngokuthe ngqo neNkqubo yoLawulo lweeBhetri (i-BMS) yesithuthi, sinokuhambisa amandla ombane aphezulu kakhulu—aqala kwi-50 kW ukuya kwi-350 kW nangaphezulu. Ngokususa i-OBC bottleneck, i-DCFC inokugcwalisa i-80% yebhetri kwimizuzu eli-15 ukuya kwengama-45, xa kuthelekiswa neeyure ezi-4 ukuya kweli-10 ezifunekayo kwiNqanaba lesi-2.

Ukusebenza kakuhle kunye noLawulo lobushushu

Ukuguqulwa kuvelisa ubushushu. Kwitshaja ye-L2, ubushushu buveliswa ngaphakathi emotweni, nto leyo ebangela ukuba inkqubo yokupholisa yangaphakathi yesithuthi isebenze. Kwitshaja ye-L3, ubushushu obukhulu obuveliswa ngexesha lokuguqulwa kwe-AC ukuya kwi-DC bulawulwa ziinkqubo zolwelo okanye zokupholisa umoya zesikhululo sokutshaja. Ngaphezu koko, ukutshaja kwe-DC ngesantya esiphezulu kufuna iintambo ezikhethekileyo ezipholisiweyo zolwelo ukuthintela ukunyibilika phantsi kwemithwalo yamandla agqithisileyo (ngokuqhelekileyo ukusuka kwi-350A ukuya kwi-500A).

Isahluko 3: Ukutshaja kweNqanaba lesi-2: Iinkcukacha zoBugcisa, iiNzuzo, kunye neLogic yokuya
