Ngokuthuthuka okusheshayo kwemakethe ye-EV, izinqwaba zokushaja ze-DC seziyingxenye ebalulekile yengqalasizinda yokushaja ye-EV ngenxa yezici zazo, futhi ukubaluleka kweziteshi zokushaja ze-DC kuye kwaba yinto evelele kakhulu. Uma kuqhathaniswa nezinqwaba zokushaja ze-AC,Izinqwaba zokushaja ze-DCziyakwazi ukunikeza amandla e-DC ngqo kumabhethri e-EV, okunciphisa kakhulu isikhathi sokushaja futhi ngokuvamile zishaja kufika kumaphesenti angu-80 ngaphansi kwemizuzu engama-30. Le ndlela yokushaja esebenza kahle yenza isetshenziswe kabanzi kune-Izinqwaba zokushaja ze-ACezindaweni ezifana neziteshi zokushaja zomphakathi, izikhungo zezentengiselwano kanye nezindawo zezinsizakalo zomgwaqo omkhulu.
Ngokwesimiso sobuchwepheshe, inqwaba yokushaja ye-DC iqaphela kakhulu ukuguqulwa kwamandla kagesi ngokusebenzisa ukunikezwa kwamandla okushintshashintsha okuvama kakhulu kanye nemodyuli yamandla. Isakhiwo sayo sangaphakathi sihlanganisa i-rectifier, isihlungi kanye nohlelo lokulawula ukuqinisekisa ukuzinza nokuphepha komthamo wamandla okukhipha. Okwamanje, izici ezihlakaniphile zeIzinqwaba zokushaja ze-DCziyathuthukiswa kancane kancane, futhi imikhiqizo eminingi ifakwe izixhumi zokuxhumana ezivumela ukusebenzisana kwedatha ngesikhathi sangempela nama-EV kanye namagridi kagesi ukuze kuthuthukiswe inqubo yokushaja kanye nokuphathwa kokusetshenziswa kwamandla. Iphrofayili yayo yesimiso sobuchwepheshe ihlanganisa ikakhulukazi izici ezilandelayo:
1. Inqubo yokulungisa: Ama-pile okushaja e-DC anezilungisi ezakhelwe ngaphakathi ukuze kufezwe ukushaja ngokuguqula amandla e-AC abe amandla e-DC. Le nqubo ihilela umsebenzi wokubambisana wama-diode amaningi ukuguqula isigamu sesonto esihle nesibi se-AC sibe yi-DC.
2. Ukuhlunga kanye Nokulawulwa Kwevolumu: Amandla e-DC aguquliwe alungiswa ngesihlungi ukuze kuqedwe ukuguquguquka kwamandla kagesi futhi kuqinisekiswe ukuzinza kwamandla kagesi okukhiphayo. Ngaphezu kwalokho, umlawuli wevolumu uzolawula amandla kagesi ukuqinisekisa ukuthi amandla kagesi ahlala ngaphakathi kwebanga eliphephile ngesikhathi senqubo yokushaja.
3. Uhlelo lokulawula oluhlakaniphile: Ama-pile okushaja e-DC anamuhla afakwe uhlelo lokulawula oluhlakaniphile oluqapha isimo sokushaja ngesikhathi sangempela futhi lulungisa ngokuguquguqukayo amandla okushaja kanye ne-voltage ukuze kuthuthukiswe ukusebenza kahle kokushaja futhi kuvikelwe ibhethri ngezinga eliphezulu.
4. Izinqubo zokuxhumana: Ukuxhumana phakathi kwamashaja e-DC nama-EV kuvame ukusekelwe ezinqubweni ezijwayelekile ezifana ne-IEC 61850 kanye ne-ISO 15118, ezivumela ukushintshaniswa kolwazi phakathi kweshaja nemoto, okuqinisekisa ukuphepha nokusebenza kahle kwenqubo yokushaja.
Ngokuphathelene nezindinganiso zokushaja ngemuva komkhiqizo, izikhala zokushaja ze-DC zilandela izindinganiso eziningana zomhlaba wonke nezesizwe ukuqinisekisa ukuphepha nokuhambisana. Izinga le-IEC 61851 elikhishwe yi-International Electrotechnical Commission (IEC) linikeza isiqondiso mayelana nokuxhumana phakathi kwama-EV nezindawo zokushaja, lihlanganisa izixhumanisi zikagesi kanye nezinqubo zokuxhumana. E-ChinaI-GB/T 2023Ngakolunye uhlangothi, indinganiso ye-4 ichaza izidingo zobuchwepheshe kanye nemininingwane yokuphepha yama-pile okushaja. Zonke lezi zindinganiso zilawula amazinga okukhiqiza nokuklama ama-pile okushaja ngezinga elithile, futhi ngezinga elithile, zisiza ukukhuthaza intuthuko enempilo yemakethe yezimoto ezintsha zikagesi zamandla kanye nezimboni ezizisekelayo.
Ngokuphathelene nohlobo lwezibhamu zokushaja zenqwaba yokushaja ye-DC, inqwaba yokushaja ye-DC ingahlukaniswa ibe yinqwaba yokushaja yesibhamu esisodwa, isibhamu esiphindwe kabili kanye nesibhamu esiningi. Izinqwaba zokushaja zesibhamu esisodwa zifanele iziteshi zokushaja ezincane, kuyilapho izinqwaba zokushaja zezibhamu ezimbili kanye nezibhamu eziningi zifanelekela izakhiwo ezinkulu ukuze kuhlangatshezwane nesidingo esikhulu sokushaja. Izigxobo zokushaja zezibhamu eziningi zithandwa kakhulu ngoba zingakhonza ama-EV amaningi ngesikhathi esisodwa, okwandisa kakhulu ukusebenza kahle kokushaja.
Okokugcina, kukhona umbono wemakethe yezinqwaba zokushaja: ikusasa lezinqwaba zokushaja ze-DC lizogcwala amandla njengoba ubuchwepheshe buthuthuka futhi isidingo semakethe sikhula. Ukuhlanganiswa kwamagridi ahlakaniphile, izimoto ezingenabashayeli kanye namandla avuselelekayo kuzoletha amathuba amasha angakaze abonwe ezinqwaba zokushaja ze-DC. Ngokuthuthuka okuqhubekayo kwesikhathi esiluhlaza, sikholelwa ukuthi izinqwaba zokushaja ze-DC ngeke zinikeze abasebenzisi ulwazi lokushaja olulula kakhulu, kodwa futhi ekugcineni zizofaka isandla ekuthuthukisweni okusimeme kwesistimu yonke ye-e-mobility.
Uma ufuna ukwazi kabanzi mayelana nokubonisana ngesiteshi sokushaja, ungachofoza ku-:Kukunike ukuqonda okuningiliziwe ngemikhiqizo emisha yesitayela - inqwaba yokushaja i-AC
