Ngenxa yophuhliso olukhawulezileyo lwemarike ye-EV, ii-DC charging piles ziye zaba yinxalenye ebalulekileyo yeziseko zokutshaja ze-EV ngenxa yeempawu zazo, kwaye ukubaluleka kwezikhululo zokutshaja ze-DC kuye kwanda. Xa kuthelekiswa nee-AC charging piles,Iinqwaba zokutshaja zeDCziyakwazi ukubonelela ngombane we-DC ngqo kwiibhetri ze-EV, nto leyo enciphisa kakhulu ixesha lokutshaja kwaye zihlala zitshaja ukuya kuthi ga kwi-80% ngaphantsi kwemizuzu engama-30. Le ndlela yokutshaja esebenzayo yenza ukuba isetyenziswe kakhulu kuneIinqwaba zokutshaja ze-ACkwiindawo ezifana nezikhululo zikawonke-wonke zokutshaja, amaziko orhwebo kunye neendawo zeenkonzo zoohola bendlela.
Ngokwemigaqo yobugcisa, inqwaba yokutshaja ye-DC ilawula ukuguqulwa kwamandla ombane ngokusebenzisa umbane otshintsha rhoqo kunye nemodyuli yamandla. Ulwakhiwo lwayo lwangaphakathi luquka i-rectifier, isihluzi kunye nenkqubo yokulawula ukuqinisekisa uzinzo kunye nokhuseleko lwamandla okukhupha. Okwangoku, iimpawu ezikrelekrele zeIinqwaba zokutshaja zeDCziyaphuculwa kancinci kancinci, kwaye iimveliso ezininzi zixhotyiswe ngemijelo yonxibelelwano evumela ukusebenzisana kwedatha ngexesha langempela nee-EV kunye neegridi zamandla ukuphucula inkqubo yokutshaja kunye nolawulo lokusetyenziswa kwamandla. Iprofayili yayo yomgaqo-nkqubo wobugcisa ibandakanya ikakhulu ezi zinto zilandelayo:
1. Inkqubo yokulungisa: Iipali zokutshaja ze-DC zinezixhobo zokulungisa ezakhelwe ngaphakathi ukuze zifezekise ukutshaja ngokuguqula amandla e-AC abe ngamandla e-DC. Le nkqubo ibandakanya umsebenzi wentsebenziswano wee-diode ezininzi ukuguqula iiveki ezinesiqingatha ze-AC zibe yi-DC ezilungileyo nezimbi.
2. Ulawulo lokucoca kunye noLawulo lweVoltage: Amandla e-DC aguquliweyo alungiswa ngesihluzo ukuze kupheliswe ukuguquguquka kwamandla ombane kwaye kuqinisekiswe uzinzo lwamandla ombane aphumayo. Ukongeza, umlawuli wevolthi uya kulawula amandla ombane ukuqinisekisa ukuba amandla ombane ahlala ngaphakathi koluhlu olukhuselekileyo ngexesha lenkqubo yokutshaja.
3. Inkqubo yokulawula ekrelekrele: Iipali zokutshaja zeDC zanamhlanje zixhotyiswe ngenkqubo yokulawula ekrelekrele ejonga imeko yokutshaja ngexesha langempela kwaye ilungisa ngokuguquguqukayo umsinga wokutshaja kunye nevolthi ukuze kuphuculwe ukusebenza kakuhle kokutshaja kwaye kukhuselwe ibhetri kangangoko.
4. Iiprotokholi zonxibelelwano: Unxibelelwano phakathi kweetshaja zeDC kunye nee-EV ludla ngokusekwe kwiiprotokholi ezisemgangathweni ezifana ne-IEC 61850 kunye ne-ISO 15118, ezivumela ukutshintshiselana ngolwazi phakathi kwetshaja kunye nesithuthi, ukuqinisekisa ukhuseleko kunye nokusebenza kakuhle kwenkqubo yokutshaja.
Ngokuphathelele imigangatho yemveliso yokutshaja emva kokutshaja, izikhundla zokutshaja ze-DC zilandela imigangatho emininzi yamazwe ngamazwe neyesizwe ukuqinisekisa ukhuseleko kunye nokuhambelana. Umgangatho we-IEC 61851 okhutshwe yiKhomishini ye-International Electrotechnical Commission (IEC) unika isikhokelo malunga nonxibelelwano phakathi kwee-EV kunye nezibonelelo zokutshaja, kuquka iindawo zokunxibelelana zombane kunye neenkqubo zonxibelelwano. E-ChinaI-GB/T 2023Kwelinye icala, umgangatho we-4 uchaza iimfuno zobugcisa kunye neenkcukacha zokhuseleko lweepali zokutshaja. Yonke le migangatho ilawula imigangatho yoshishino lokuvelisa noyilo lweepali zokutshaja ukuya kwinqanaba elithile, kwaye ukuya kwinqanaba elithile, inceda ekukhuthazeni uphuhliso olusempilweni lwemarike yezithuthi ezintsha zombane zamandla kunye namashishini azo axhasayo.
Ngokuphathelele uhlobo lwezibhamu zokutshaja ze-DC charging pile, i-DC charging pile inokwahlulwa ibe yi-single-gun, double-gun kunye ne-multi-gun charging pile. Ii-single-gun charging piles zifanelekile kwizikhululo ezincinci zokutshaja, ngelixa ii-dual-gun kunye ne-multi-gun charging piles zifanelekile kwiindawo ezinkulu ukuhlangabezana nemfuno ephezulu yokutshaja. Ii-multi-gun charging posts zithandwa kakhulu kuba zinokukhonza ii-EV ezininzi ngaxeshanye, nto leyo eyandisa kakhulu ukusebenza kakuhle kokutshaja.
Okokugqibela, kukho umbono wemarike yeenqwaba zokutshaja: ikamva leenqwaba zokutshaja zeDC ngokuqinisekileyo liza kuba namandla amaninzi njengoko ubuchwepheshe buqhubela phambili kwaye imfuno yemarike ikhula. Ukudityaniswa kweegridi ezikrelekrele, iimoto ezingenamqhubi kunye namandla avuselelekayo kuya kuzisa amathuba amatsha angazange abonwe ngaphambili kwiinqwaba zokutshaja zeDC. Ngophuhliso olongezelelekileyo lwexesha eliluhlaza, sikholelwa ukuba iinqwaba zokutshaja zeDC aziyi kubonelela abasebenzisi ngamava okutshaja alula ngakumbi, kodwa ekugqibeleni ziya kuncedisa kuphuhliso oluzinzileyo lwenkqubo yonke ye-e-mobility.
Ukuba ufuna ukwazi okungakumbi malunga neengcebiso zesikhululo sokutshaja, ungacofa ku:Ukukunika ulwazi oluthe kratya malunga neemveliso ezintsha zefashoni - inqwaba yokutshaja ye-AC
