Chifukwa cha kukula kwa msika wa magetsi amagetsi (EV), ma DC charging piles akhala gawo lofunika kwambiri la zomangamanga za magetsi amagetsi chifukwa cha makhalidwe awoawo, ndipo kufunika kwa malo ochapira magetsi amagetsi amagetsi a DC kwakhala kodziwika kwambiri. Poyerekeza ndi ma AC charging piles,Ma DC charging pilesamatha kupereka mphamvu ya DC mwachindunji ku mabatire a EV, zomwe zimachepetsa kwambiri nthawi yochaja ndipo nthawi zambiri zimachaja mpaka 80 peresenti m'mphindi zosakwana 30. Njira yothandiza yochaja iyi imapangitsa kuti igwiritsidwe ntchito kwambiri kuposaMa AC charging pilesm'malo monga malo ochapira anthu onse, malo ogulitsira ndi m'malo ochitira ntchito zapamsewu.
Ponena za mfundo zaukadaulo, mulu wa DC charging makamaka umakwaniritsa kusintha kwa mphamvu zamagetsi kudzera mumagetsi osinthira pafupipafupi komanso module yamagetsi. Kapangidwe kake kamkati kamaphatikizapo chosinthira, fyuluta ndi makina owongolera kuti zitsimikizire kukhazikika ndi chitetezo cha mphamvu yotulutsa. Pakadali pano, mawonekedwe anzeru aMa DC charging pilesakukulitsidwa pang'onopang'ono, ndipo zinthu zambiri zili ndi njira zolumikizirana zomwe zimathandiza kulumikizana kwa deta nthawi yeniyeni ndi ma EV ndi ma gridi amagetsi kuti zithandizire bwino njira yolipirira komanso kasamalidwe ka mphamvu. Mfundo zake zaukadaulo zimaphatikizapo zinthu izi:
1. Njira yokonzanso: Ma pile a DC charging ali ndi ma rectifier omangidwa mkati kuti athe kutsitsa posintha mphamvu ya AC kukhala mphamvu ya DC. Njirayi imaphatikizapo ntchito yogwirizana ya ma diode angapo kuti asinthe theka la sabata zabwino ndi zoyipa za AC kukhala DC.
2. Kusefa ndi Kulamulira Voltage: Mphamvu ya DC yosinthidwa imakonzedwa ndi fyuluta kuti ichotse kusinthasintha kwa magetsi ndikuwonetsetsa kuti mphamvu yotulutsa ikhazikika. Kuphatikiza apo, chowongolera magetsi chidzawongolera magetsi kuti chitsimikizire kuti magetsi nthawi zonse amakhala mkati mwa malo otetezeka panthawi yochaja.
3. Dongosolo lowongolera lanzeru: Ma DC charger pile amakono ali ndi dongosolo lowongolera lanzeru lomwe limayang'anira momwe chaji imakhalira nthawi yeniyeni ndikusintha mphamvu ya chaji ndi magetsi kuti liwongolere bwino chaji ndikuteteza batri mokwanira.
4. Ma protocol olumikizirana: Kulankhulana pakati pa ma DC charger ndi ma EV nthawi zambiri kumadalira ma protocol ofanana monga IEC 61850 ndi ISO 15118, omwe amalola kusinthana chidziwitso pakati pa charger ndi galimoto, kuonetsetsa kuti njira yolipirira ndi yotetezeka komanso yogwira ntchito bwino.
Ponena za miyezo yolipirira zinthu zotumizira, malo olipirira zinthu zotumizira ...GB/T 2023Komabe, muyezo wa 4 umafotokoza zofunikira zaukadaulo ndi zofunikira zachitetezo cha ma pile ochajira. Miyezo yonseyi imayang'anira miyezo ya makampani opanga ndi kupanga ma pile ochajira pamlingo winawake, ndipo pamlingo wina, imathandizira kupititsa patsogolo chitukuko chabwino cha msika wa magalimoto atsopano amagetsi ndi mafakitale othandizira.
Ponena za mtundu wa mfuti zochapira za mulu wa DC charging, mulu wa DC charging ukhoza kugawidwa m'magulu awiri, awiri ndi angapo. Milu ya mfuti imodzi ndi yoyenera malo ang'onoang'ono ochapira, pomwe milu ya mfuti ziwiri ndi yambiri ndi yoyenera malo akuluakulu kuti akwaniritse kufunikira kwakukulu kwa charging. Malo ochapira mfuti zambiri ndi otchuka kwambiri chifukwa amatha kutumikira ma EV ambiri nthawi imodzi, zomwe zimawonjezera kwambiri mphamvu ya charging.
Pomaliza, pali chiyembekezo cha msika wa milu yochapira: tsogolo la milu yochapira ya DC lidzakhala lodzaza ndi kuthekera pamene ukadaulo ukupita patsogolo komanso kufunikira kwa msika kukukula. Kuphatikiza kwa ma gridi anzeru, magalimoto opanda dalaivala ndi mphamvu zongowonjezwdwanso kudzabweretsa mwayi watsopano wosayerekezeka wa milu yochapira ya DC. Kudzera mu chitukuko chowonjezereka cha nthawi yobiriwira, tikukhulupirira kuti milu yochapira ya DC sidzangopatsa ogwiritsa ntchito mwayi wochapira wosavuta, komanso pamapeto pake idzathandizira pakukula kokhazikika kwa chilengedwe chonse cha e-mobility.
Ngati mukufuna kudziwa zambiri zokhudza upangiri wa malo ochajira, mutha kudina:Kumvetsetsani mwatsatanetsatane za zinthu zatsopano zomwe zikuchitika - mulu wochapira wa AC
