Ngokuthuthuka okusheshayo kwemakethe ye-EV, izinqwaba zokushaja ze-DC seziyingxenye ebalulekile yengqalasizinda yokushaja ye-EV ngenxa yezimpawu zazo, futhi nokubaluleka kweziteshi zokushaja ze-DC sekuya ngokuya kugqama. Uma kuqhathaniswa nezinqwaba zokushaja i-AC,DC ukushaja izinqwabaziyakwazi ukunikeza amandla e-DC ngokuqondile kumabhethri e-EV, zinciphisa kakhulu isikhathi sokushaja futhi ngokuvamile zishaja kufika kumaphesenti angu-80 ngaphansi kwamaminithi angu-30. Le ndlela yokushaja ephumelelayo iyenza isetshenziswe kabanzi kuneIzinqwaba zokushaja i-ACezindaweni ezifana neziteshi zokushaja zomphakathi, izikhungo zezentengiselwano nezindawo zesevisi yomgwaqo omkhulu.
Ngokwesimiso sobuchwepheshe, inqwaba yokushaja i-DC ibona ngokuyinhloko ukuguqulwa kwamandla kagesi ngokusebenzisa ukunikezwa kwamandla okushintshwa kwemvamisa ephezulu kanye nemojula yamandla. Isakhiwo sayo sangaphakathi sihlanganisa isilungisi, isihlungi kanye nohlelo lokulawula ukuze kuqinisekiswe ukuzinza nokuphepha kokuphumayo kwamanje. Phakathi naleso sikhathi, izici ezihlakaniphile zeDC ukushaja izinqwabazithuthukiswa kancane kancane, futhi imikhiqizo eminingi ifakwe izixhumanisi zokuxhumana ezivumela ukusebenzisana kwedatha yesikhathi sangempela nama-EV namagridi kagesi ukuze kuthuthukiswe inqubo yokushaja nokuphathwa kokusetshenziswa kwamandla. Iphrofayili yayo yesimiso sobuchwepheshe ikakhulukazi ihlanganisa izici ezilandelayo:
1. Inqubo yokulungisa: Izinqwaba zokushaja ze-DC zinezilungisi ezakhelwe ngaphakathi ukuze zifinyelele ukushaja ngokuguqula amandla e-AC abe amandla e-DC. Le nqubo ibandakanya umsebenzi wokuhlanganyela wama-diode amaningi ukuze kuguqulwe isigamu seviki elihle nelibi le-AC libe yi-DC.
2. I-Filtering and Voltage Regulation: Amandla e-DC aguquliwe enziwa bushelelezi ngesihlungi ukuze kuqedwe ukushintshashintsha kwamanje nokuqinisekisa ukuzinza kokuphumayo kwamanje. Ngaphezu kwalokho, isilawuli sikagesi sizolawula amandla kagesi ukuze siqinisekise ukuthi i-voltage ihlala ingaphakathi kwebanga eliphephile phakathi nenqubo yokushaja.
3. Uhlelo lokulawula oluhlakaniphile: Izinqwaba zokushaja ze-DC zanamuhla zifakwe isistimu yokulawula ehlakaniphile eqapha isimo sokushaja ngesikhathi sangempela futhi ilungise ngokuguquguqukayo ukushaja kwamanje kanye ne-voltage ukuze kuthuthukiswe ukusebenza kahle kokushaja futhi ivikele ibhethri ngezinga eliphezulu kakhulu.
4. Izimiso zokuxhumana: Ukuxhumana phakathi kwamashaja e-DC nama-EV ngokuvamile kusekelwe kuzivumelwano ezijwayelekile ezifana ne-IEC 61850 ne-ISO 15118, ezivumela ukushintshana kolwazi phakathi kweshaja nemoto, okuqinisekisa ukuphepha nokusebenza kahle kwenqubo yokushaja.
Mayelana nezindinganiso zokushaja zomkhiqizo wokuthunyelwe, izikhala zokushaja ze-DC zilandela inani lamazinga omhlaba nawezwe ukuze kuqinisekiswe ukuphepha nokuhambisana. Izinga le-IEC 61851 elikhishwe yi-International Electrotechnical Commission (IEC) linikeza isiqondiso mayelana nokuxhumana phakathi kwama-EV nezindawo zokushaja, ezihlanganisa izixhumanisi zikagesi kanye nezivumelwano zokuxhumana. ElaseShayinaI-GB/T 20234, ngakolunye uhlangothi, inika imininingwane ngezidingo zobuchwepheshe kanye nokucaciswa kokuphepha kwezinqwaba zokushaja. Wonke lawa mazinga alawula amazinga embonini yokukhiqiza nokuklama inqwaba eshajayo ngokwezinga elithile, futhi ngokwezinga elithile, asize ukukhuthaza intuthuko enempilo yemakethe yezimoto zikagesi zamandla amasha kanye nezimboni ezizisekelayo.
Mayelana nohlobo lwezibhamu ezishajayo zenqwaba yokushaja i-DC, inqwaba yokushaja ye-DC ingahlukaniswa ibe yinqwaba yesibhamu esisodwa, isibhamu esikabili kanye nenqwaba yokushaja izibhamu. Izinqwaba zokushaja ngesibhamu esisodwa zilungele iziteshi zokushaja ezincane, kuyilapho izinqwaba zokushaja ezinezibhamu ezimbili kanye nezibhamu eziningi zilungele izakhiwo ezinkulu ukuhlangabezana nesidingo esikhulu sokushaja. Okuthunyelwe okushaja izibhamu eziningi kudume kakhulu ngoba kungasebenzisa ama-EV amaningi ngesikhathi esisodwa, okukhulisa ngokumangazayo ukushaja ngendlela encomekayo.
Okokugcina, kunombono wemakethe yenqwaba eshajayo: ikusasa lezinqwaba zokushaja i-DC liqinisekile ukuthi lizogcwala amandla njengoba intuthuko yobuchwepheshe kanye nesidingo semakethe sikhula. Ukuhlanganiswa kwamagridi ahlakaniphile, izimoto ezingashayeli namandla avuselelekayo kuzoletha amathuba amasha angakaze abonwe ezinqwaba zokushaja ze-DC. Ngokuqhubeka nokuthuthuka kwenkathi yohlaza, sikholelwa ukuthi izinqwaba zokushaja ze-DC ngeke zigcine nje ngokunikeza abasebenzisi ulwazi olulula lokushaja, kodwa futhi zizofaka isandla ekuthuthukisweni okusimeme kwayo yonke i-e-mobility ecosystem.
Uma ufuna ukwazi okwengeziwe mayelana ne-consultancy yesiteshi sokushaja, ungachofoza ku-:Thatha ukuqonda okuningiliziwe kwemikhiqizo emisha yethrendi - inqwaba yokushaja i-AC
