Njengoba imboni yezimoto zamandla amasha ithuthuka, inqwaba yokushaja ye-DC, njengesikhungo esiyinhloko sokushaja ngokushesha izimoto zikagesi, kancane kancane ithatha isikhundla esibalulekile emakethe, futhiI-BeiHai Power(I-China), njengelungu lensimu entsha yamandla, nayo yenza iminikelo ebalulekile ekwandiseni nasekukhuthazeni amandla amasha. Kulesi sihloko, sizochaza kabanzi ngama-DC charging piles ngokuya ngobuchwepheshe bokusebenzisa, isimiso sokusebenza, amandla okushaja, isakhiwo sokuhlukaniswa, izimo zokusetshenziswa kanye nezici.
Ukusetshenziswa kobuchwepheshe
Inqwaba yokushaja ye-DC (ebizwa ngokuthi inqwaba yokushaja ye-DC) isebenzisa ubuchwepheshe obuthuthukisiwe be-elekthronikhi, futhi ingqikithi yayo itholakala ku-inverter yangaphakathi. Ingqikithi ye-inverter yi-inverter yangaphakathi, engashintsha ngempumelelo amandla e-AC kusuka kugridi yamandla abe amandla e-DC futhi iwanikeze ngqo ebhethrini lemoto kagesi ukuze ishaje. Le nqubo yokuguqula yenziwa ngaphakathi kweposi yokushaja, igwema ukulahlekelwa ukuguqulwa kwamandla yi-inverter ye-EV ebhodini, okuthuthukisa kakhulu ukusebenza kahle kokushaja. Ngaphezu kwalokho, iposi yokushaja ye-DC ifakwe uhlelo lokulawula oluhlakaniphile olulungisa ngokuzenzakalelayo amandla okushaja kanye ne-voltage ngokuya ngesimo sebhethri sesikhathi sangempela, okuqinisekisa inqubo yokushaja ephephile nephumelelayo.
Isimiso Sokusebenza
Umgomo wokusebenza wenqwaba yokushaja ye-DC uhilela kakhulu izici ezintathu: ukuguqulwa kwamandla, ukulawula kwamanje kanye nokuphathwa kokuxhumana:
Ukuguqulwa kwamandla:Inqwaba yokushaja ye-DC kuqala idinga ukuguqula amandla e-AC abe amandla e-DC, atholakala yi-rectifier yangaphakathi. I-rectifier ivame ukusebenzisa isekethe ye-bridge rectifier, eyakhiwa ama-diode amane, futhi ingaguqula izingxenye ezingezinhle nezingezinhle zamandla e-AC zibe amandla e-DC ngokulandelana.
Ukulawula kwamanje:Amashaja e-DC adinga ukulawula ugesi wokushaja ukuqinisekisa ukuphepha nokusebenza kahle kwenqubo yokushaja. Ukulawulwa kwamanje kuqashelwa yisilawuli sokushaja ngaphakathi kwenqwaba yokushaja, esingalungisa ngokuzenzakalelayo usayizi wamandla okushaja ngokuya ngesidingo semoto kagesi kanye nomthamo wenqwaba yokushaja.
Ukuphathwa kokuxhumana:Ama-DC pile okushaja ngokuvamile anomsebenzi wokuxhumana nemoto kagesi ukuze kufezwe ukuphathwa nokuqapha inqubo yokushaja. Ukuphathwa kokuxhumana kufezwa ngemojuli yokuxhumana engaphakathi kwenqwaba yokushaja, engenza ukuxhumana okubili nemoto kagesi, okuhlanganisa ukuthumela imiyalo yokushaja kusuka enqwabeni yokushaja kuya emotweni kagesi kanye nokuthola ulwazi lwesimo semoto kagesi.
Amandla okushaja
Ama-DC charging pile aziwa ngokukwazi kwawo ukushaja ngamandla aphezulu. Kunezinhlobo ezahlukeneAmashaja e-DCemakethe, okuhlanganisa u-40kW, 60kW, 120kW, 160kW ngisho no-240kW. Lawa mashaja anamandla aphezulu ayakwazi ukugcwalisa kabusha izimoto zikagesi ngokushesha ngesikhathi esifushane, okunciphisa kakhulu isikhathi sokushaja. Isibonelo, i-DC charging post enamandla angu-100kW, ngaphansi kwezimo ezifanele, ingashaja ibhethri lemoto kagesi ngokugcwele cishe phakathi kwesigamu sehora kuya ehoreni. Ubuchwepheshe bokushaja kakhulu buyandisa ngisho namandla okushaja abe ngaphezu kuka-200kW, okunciphisa isikhathi sokushaja futhi kulethe lula kakhulu kubasebenzisi bezimoto zikagesi.
Ukuhlukaniswa kanye nesakhiwo
Izinqwaba zokushaja ze-DC zingahlukaniswa ngobukhulu obuhlukene, njengosayizi wamandla, inani lezibhamu zokushaja, isimo sesakhiwo kanye nendlela yokufaka.
Isakhiwo senqwaba yokushaja:Izinqwaba zokushaja ze-DC zingahlukaniswa zibe yinqwaba yokushaja ye-DC ehlanganisiwe kanye nenqwaba yokushaja ye-DC ehlukanisiwe.
Izindinganiso zesikhungo sokushaja:ingahlukaniswa ngezinga lesiShayina:I-GB/T; Izinga laseYurophu: IEC (IKhomishini Yezobuchwepheshe Bomhlaba Wonke); Izinga lase-US: I-SAE (Inhlangano Yonjiniyela Bezimoto base-United States); Izinga laseJapan: I-CHAdeMO (eJapane).
Ukuhlukaniswa kwezibhamu zokushaja:Ngokwenani lezibhamu zokushaja, inqwaba yokushaja ingahlukaniswa ibe yizibhamu eyodwa, ezimbili, ezintathu, futhi ingenziwa ngezifiso ngokwesidingo sangempela.
Ukwakheka kwesakhiwo sangaphakathi seposi yokushaja:Ingxenye kagesi yeIposi lokushaja le-DCIqukethe isekethe eyinhloko kanye nesekethe yesibili. Ukufakwa kwesekethe eyinhloko kungamandla e-AC ezigaba ezintathu, aguqulwa abe amandla e-DC amukelekayo ebhethri yi-module yokushaja (i-module ye-rectifier) ngemuva kokufaka i-circuit breaker kanye ne-AC smart meter, bese ixhunywe ku-fuse kanye nesibhamu seshaja ukuze ishaje imoto kagesi. Isekethe yesibili iqukethe isilawuli senqwaba yokushaja, isifundi sekhadi, isikrini sokubonisa, i-DC meter, njll. Ihlinzeka ngokulawula 'kokuqala-ukuma' kanye nokusebenza 'kokuyeka okuphuthumayo', kanye nemishini yokusebenzisana kwabantu nomshini njengokukhanya kwesiginali kanye nesikrini sokubonisa.
Isimo Sokusetshenziswa
Izinqwaba zokushaja ze-DCzisetshenziswa kabanzi ezindaweni ezahlukene ezidinga ukugcwaliswa kabusha kukagesi ngokushesha ngenxa yezici zazo zokushaja okusheshayo. Emkhakheni wezokuthutha zomphakathi, njengamabhasi asedolobheni, amatekisi nezinye izimoto ezihamba kakhulu, inqwaba yokushaja ye-DC inikeza isisombululo sokushaja okusheshayo esithembekile. Ezindaweni zezinsizakalo zomgwaqo omkhulu, ezitolo ezinkulu, ezindaweni zokupaka izimoto zomphakathi nakwezinye izindawo zomphakathi, amanqwaba okushaja e-DC nawo ahlinzeka ngezinsizakalo zokushaja ezilula kubasebenzisi bezimoto zikagesi ezidlulayo. Ngaphezu kwalokho, amanqwaba okushaja e-DC avame ukufakwa ezindaweni ezikhethekile njengezindawo zezimboni kanye namapaki okuthutha ukuze kuhlangatshezwane nezidingo zokushaja zezimoto ezikhethekile epaki. Ngokuthandwa kwezimoto ezintsha zamandla, izindawo zokuhlala nazo ziye zaqala kancane kancane ukufaka amanqwaba okushaja e-DC ukuze kuhlinzekwe kalula izimoto zikagesi zezakhamuzi.
Izici
Ukusebenza kahle kanye nesivinini: Ukuguqulwa kwamandla enqwaba yokushaja ye-DC kuqedwa ngaphakathi kwenqwaba, kugwema ukulahlekelwa yi-inverter esebhodini futhi kwenza ukushaja kube ngcono kakhulu. Ngesikhathi esifanayo, amandla okushaja aphezulu enza izimoto zikagesi zishajwe ngokushesha ngesikhathi esifushane.
Kusebenza kabanzi: Ama-DC charger pile afanelekela izimo ezahlukahlukene zokusetshenziswa, okuhlanganisa ezokuthutha zomphakathi, iziteshi ezikhethekile, izindawo zomphakathi kanye nemiphakathi yokuhlala, njll., ukuze kuhlangatshezwane nezidingo zokushaja zabasebenzisi abahlukene.
Kuhlakaniphile futhi kuphephile: Ama-pile okushaja e-DC afakwe uhlelo lokulawula oluhlakaniphile angaqapha isimo sebhethri ngesikhathi sangempela futhi alungise ngokuzenzakalelayo amapharamitha okushaja ukuqinisekisa ukuphepha nokuzinza kwenqubo yokushaja.
Khuthaza ukuthuthukiswa kwezimoto ezintsha zamandla: ukusetshenziswa kabanzi kwenqwaba yokushaja ye-DC kunikeza ukwesekwa okuqinile kokuthandwa kwezimoto ezintsha zamandla futhi kukhuthaza ukuthuthukiswa okusheshayo kwemboni yezimoto ezintsha zamandla.
