Ngokuthuthuka okusheshayo kwemakethe ye-EV, ama-DC ukushaja ama-Piles asephenduke ingxenye ebalulekile yengqalasizinda ye-EV yokushaja ngenxa yezimpawu zawo, kanye nokubaluleka kweziteshi zokushaja kwe-DC kuye kwavela ngokwengeziwe. Qhathanisa ne-ac ukushaja izinqwaba,I-DC ishaja izinqwababayakwazi ukuhlinzeka ngamandla we-DC ngqo kumabhethri e-eV, ukunciphisa kakhulu isikhathi sokushaja kanye nokuvama ukushaja kuze kube ngamaphesenti angama-80 ngaphansi kwemizuzu engama-30. Le ndlela yokushaja esebenza kahle yenza kube nzima kakhulu kuneI-AC ishaja izinqwabaEzindaweni ezinjengeziteshi zokushaja komphakathi, izikhungo zezentengiselwano kanye nezindawo zenkonzo emikhulu.
Ngokwemigomo yezobuchwepheshe, i-DC ishaja inqwaba yenqwaba iyabona ukuguqulwa kwamandla kagesi ngokushintsha kwamanzi okuphezulu nokushintsha kwamandla kagesi. Isakhiwo saso sangaphakathi sifaka uhlelo, ukuhlunga nokulawula uhlelo ukuqinisekisa ukuqina nokuphepha kokuphuma kwamanje. Ngaleso sikhathi, izici ezihlakaniphile zeI-DC ishaja izinqwabaZithuthukiswa kancane kancane, futhi imikhiqizo eminingi ifakwe izinhlaka zokuxhumana ezinika amandla ukusebenzisana kwedatha yesikhathi sangempela nge-EVS kanye namagridi wamandla ukwenza ngcono inqubo yokushaja kanye nokuphathwa kokusetshenziswa kwamandla. Iphrofayili yayo yezobuchwepheshe yezobuchwepheshe ifaka phakathi izici ezilandelayo:
1 Le nqubo ifaka umsebenzi wokubambisana wama-diode amaningi wokuguqula amasonto amahle ne-hight half ac to DC.
2. Ukuhlunga kanye nokulawulwa kwamandla kagesi Ngaphezu kwalokho, uMlawuli weVoltage uzolawula i-voltage ukuqinisekisa ukuthi i-voltage ihlala ihlala phakathi kobubanzi obuphephile ngesikhathi senqubo yokushaja.
I-3. Uhlelo lokulawula oluhlakaniphile: Izinhlayiya zesimanje zokushaja kwe-DC zihlome ngohlelo oluhlakaniphile lokulawula oluqapha isimo sokushaja ngesikhathi sangempela futhi luguqula amandla okukhokhisa kwamanje kanye ne-voltage ukwenza kahle ibhethri ngezinga eliphakeme.
I-4. Imigomo yokuxhumana: Ukuxhumana phakathi kwamashaja e-DC kanye ne-EVS kuvame ukususelwa kumaphrothokholi ajwayelekile afana ne-IEC 61850 ne-ISO 15118, okuvumela ukuphepha kanye nenqubo yenqubo yokushaja.
Ngokuphathelene namazinga omkhiqizo wePost Post, okuthunyelwe kwe-DC kulandela amazinga amaningi wamazwe aphesheya kanye namazwe ukuqinisekisa ukuphepha nokuhambisana. I-IEC 61851 I-Standard Ikhishwe yi-International Electrotechnical Commission (IEC) ihlinzeka ukuholwa ngokuxhumeka phakathi kwe-EVS kanye nokushaja izikhungo zokushaja, ukumboza ukuxhumana kukagesi kanye nezinqubomgomo zokuxhumana. ChinaGB / T 20234 Okujwayelekile, ngakolunye uhlangothi, imininingwane yemiklomelo yezobuchwepheshe kanye nokuphepha okucacisiwe kokushaja izinqwaba. Zonke lezi zindinganiso zilawula izindinganiso zemboni yokukhiqiza i-Pile yokushaja kanye nokuklama ngezinga elithile, futhi ngezinga elithile, zisize ukukhuthaza ukuthuthukiswa okunempilo kwezimoto ezintsha zegesi kanye nemikhakha yazo esekelayo.
Ngolunye uhlobo lokushaja izibhamu zenqwaba yokushaja i-DC, inqwaba yokushaja i-DC ingahlukaniswa inqwaba yesibhamu esisodwa, izibhamu eziphindwe kabili nezibhamu. Izinhlayiya ezishaja isibhamu zilungele iziteshi ezincane zokushaja, kanti ama-bull-gun-isibhamu ashaja afanelekile ezakhiweni ezinkulu ukuze ahlangabezane nesidingo esiphakeme sokushaja. Izikhala zokushaja izibhamu eziningi zithandwa kakhulu ngoba zingasebenza ama-EV amaningi ngasikhathi sinye, ezandisa kakhulu ukukwazi ukushaja ukusebenza kahle.
Ekugcineni, kunombono wemakethe yenqwaba yokushaja: Ikusasa le-DC ukushaja izinqwaba nakanjani ligcwele amathuba njengentuthuko yezobuchwepheshe kanye nezidingo zemakethe zikhula. Inhlanganisela yama-grids ahlakaniphile, izimoto ezingenalulekayo kanye namandla avuselelekayo zizoletha amathuba amasha angenakubonwa nge-DC ukushaja izinqwaba. Ngokuthuthuka okwengeziwe kwenkathi eluhlaza, sikholwa ukuthi ama-DC ukushaja ama-Piles ngeke anikeze abasebenzisi kuphela ngesipiliyoni sokushaja esikahle, kepha ekugcineni azonikela ekuthuthukisweni okuzinzile kwalo lonke i-E-Mobility Ecosystem yonke.
Uma ufuna ukwazi kabanzi ngokubonisana kwesiteshi sokushaja, ungachofoza ku:Kukuthatha ukuqonda okuningiliziwe kwemikhiqizo emisha yokuthambekela - i-AC ishaja inqwaba
