Ngophuhliso olukhawulezayo lwemakethi ye-EV, iimfumba zokutshaja ze-DC ziye zaba yinxalenye yeziseko zokutshaja ze-EV ngenxa yeempawu zazo, kwaye ukubaluleka kwezikhululo zokutshaja ze-DC ziye zavela ngakumbi. Xa kuthelekiswa neengqumba zokutshaja ze-AC,DC ukutshaja iimfumbabayakwazi ukunika amandla e-DC ngokuthe ngqo kwiibhetri ze-EV, ukunciphisa kakhulu ixesha lokutshaja kwaye ngokuqhelekileyo batshaja ukuya kuma-80 ekhulwini ngaphantsi kwemizuzu engama-30. Le ndlela yokutshaja esebenzayo yenza ukuba isetyenziswe ngokubanzi kuneIimfumba zokutshaja ze-ACkwiindawo ezifana nezikhululo zokutshaja zikawonke-wonke, amaziko orhwebo kunye neendawo zeenkonzo zikahola wendlela.
Ngokomgaqo wobugcisa, i-DC yokutshaja imfumba ikakhulu iqonda uguqulo lwamandla ombane ngokutshintsha unikezelo lwamandla ombane omninzi kunye nemodyuli yamandla. Ubume bayo bangaphakathi bubandakanya ukulungiswa, ukucoca kunye nenkqubo yokulawula ukuqinisekisa ukuzinza kunye nokhuseleko lwemveliso yangoku. Ngeli xesha, iimpawu ezikrelekrele zeDC ukutshaja iimfumbaziphuculwa ngokuthe ngcembe, kwaye iimveliso ezininzi zixhotyiswe ngonxibelelwano lonxibelelwano oluvumela ukusebenzisana kwedatha yexesha langempela kunye nee-EVs kunye neegridi zamandla ukunyusa inkqubo yokutshaja kunye nolawulo lokusetyenziswa kwamandla. Iprofayile yayo yomgaqo wobugcisa ikakhulu ibandakanya le miba ilandelayo:
1. Inkqubo yokulungiswa: Iimfumba zokutshaja ze-DC zinee-rectifiers ezakhelwe ngaphakathi ukuphumeza ukutshaja ngokuguqula amandla e-AC kumandla e-DC. Le nkqubo ibandakanya umsebenzi wentsebenziswano weediode ezininzi ukuguqula isiqingatha seeveki ezilungileyo nezingalunganga ze-AC ukuya kwi-DC.
2. Ukucoca kunye noLawulo lweVoltage: Amandla e-DC aguqulwayo agudiswa ngesihluzo ukuphelisa ukuguquguquka kwangoku kunye nokuqinisekisa ukuzinza kwemveliso yangoku. Ukongeza, i-voltage regulator iya kulawula i-voltage ukuqinisekisa ukuba i-voltage ihlala ihlala ngaphakathi koluhlu olukhuselekileyo ngexesha lenkqubo yokutshaja.
3. Inkqubo yolawulo olukrelekrele: Iimfumba zokutshaja ze-DC zanamhlanje zixhotyiswe ngenkqubo yolawulo ekrelekrele ebeka iliso kwimeko yokutshaja ngexesha lokwenyani kwaye ihlengahlengise ngokuguquguqukayo ukutshaja kwangoku kunye nombane ukuze kuphuculwe ukusebenza kakuhle kokutshaja kunye nokukhusela ibhetri ukuya kuthi ga kwinqanaba eliphezulu.
4. Iiprothokholi zonxibelelwano: Unxibelelwano phakathi kweetshaja ze-DC kunye nee-EVs ludla ngokusekelwe kwiiprothokholi ezisemgangathweni ezifana ne-IEC 61850 kunye ne-ISO 15118, evumela ukutshintshiselana ngolwazi phakathi kwetshaja kunye nesithuthi, ukuqinisekisa ukhuseleko kunye nokusebenza kakuhle kwenkqubo yokutshaja.
Ngokumalunga nokuhlawulisa imigangatho yemveliso yesithuba, izithuba zokuhlawulisa i-DC zilandela inani lemigangatho yamazwe ngamazwe neyelizwe ukuqinisekisa ukhuseleko nokuhambelana. Umgangatho we-IEC 61851 okhutshwe yi-International Electrotechnical Commission (IEC) ibonelela ngesikhokelo malunga noqhagamshelo phakathi kwee-EVs kunye nezixhobo zokutshaja, ezigubungela ujongano lombane kunye neeprothokholi zonxibelelwano. eTshayinaGB/T 20234 umgangatho, kwelinye icala, iinkcukacha iimfuno zobugcisa kunye neenkcukacha zokhuseleko lokutshaja iimfumba. Yonke le migangatho ilawula imigangatho yokwenziwa kwemfumba yokutshaja kunye noyilo lweshishini ukuya kuthi ga kwinqanaba elithile, kwaye ukuya kuthi ga kwinqanaba elithile, inceda ukukhuthaza uphuhliso olusempilweni lwentengiso yezithuthi zombane zamandla amatsha kunye namashishini axhasayo.
Ngokubhekiselele kuhlobo lwemipu yokutshaja ye-DC yokutshaja imfumba, imfumba yokutshaja ye-DC inokohlulwa ibe yimipu enye, imipu ephindwe kabini kunye nenqwaba yokutshaja imipu emininzi. Iimfumba zokutshaja zompu omnye zilungele izikhululo zokutshaja ezincinci, ngelixa imipu emibini nemipu yokutshaja ngemipu emininzi ifanelekile kwizakhiwo ezinkulu ukuhlangabezana nemfuno ephezulu yokutshaja. Izithuba zokutshaja ngemipu emininzi zithandwa kakhulu kuba zinokusebenzisa ii-EV ezininzi ngaxeshanye, zinyusa kakhulu ukusebenza kakuhle kokutshaja.
Okokugqibela, kukho imbonakalo yentengiso yemfumba yokutshaja: ikamva leemfumba zokutshaja zeDC liqinisekile ukuba ligcwele amandla njengoko inkqubela phambili yetekhnoloji kunye nemfuno yentengiso ikhula. Ukudityaniswa kweegridi ezihlakaniphileyo, iimoto ezingaqhubiyo kunye namandla ahlaziyekayo ziya kuzisa amathuba amatsha angazange abonwe ngaphambili kwiimfumba zokutshaja ze-DC. Ngophuhliso olongezelelweyo lwexesha lohlaza, sikholelwa ukuba iimfumba zokutshaja ze-DC aziyi kubonelela abasebenzisi ngamava okutshaja alula ngakumbi, kodwa ekugqibeleni ziya kuba negalelo kuphuhliso oluzinzileyo lwenkqubo yonke ye-e-mobility.
Ukuba ufuna ukwazi ngakumbi malunga nokutshaja kwisikhululo somcebisi, ungacofa ku:Thatha ulwazi oluthe kratya malunga neemveliso ezitsha zokutshaja - imfumba yokutshaja ye-AC
