Nkhani Yankhani Yoperekedwa Kukuyambitsa kwa DC EV Charging Station

Chifukwa chakukula kwamakampani opanga magalimoto amagetsi atsopano, mulu wothamangitsa wa DC, monga malo ofunikira pakulipiritsa mwachangu magalimoto amagetsi, pang'onopang'ono akukhala pamalo ofunikira pamsika, ndipoMphamvu ya BeiHai(China), monga membala wa gawo latsopano la mphamvu, ikuperekanso zofunikira pa kutchuka ndi kupititsa patsogolo mphamvu zatsopano. M'nkhaniyi, tifotokoza zambiri za milu yolipiritsa ya DC malinga ndi ukadaulo wogwiritsa ntchito, mfundo zogwirira ntchito, mphamvu yolipirira, kapangidwe ka magulu, momwe amagwiritsidwira ntchito komanso mawonekedwe.

Kugwiritsa ntchito ukadaulo

Mulu wothamangitsa wa DC (womwe umatchedwa kuti DC charging mulu) umatenga ukadaulo wapamwamba wamagetsi, ndipo maziko ake ali mu inverter yamkati. Pakatikati pa inverter ndi inverter yamkati, yomwe imatha kusintha bwino mphamvu ya AC kuchokera pagulu lamagetsi kukhala mphamvu ya DC ndikuipereka mwachindunji ku batri yagalimoto yamagetsi kuti ipereke. Njira yosinthirayi imachitika mkati mwa positi yolipira, kupeŵa kutayika kwa kutembenuka kwa mphamvu ndi EV on-board inverter, zomwe zimathandizira kwambiri kuyendetsa bwino. Kuphatikiza apo, positi yojambulira ya DC ili ndi makina owongolera anzeru omwe amangosintha ma charger apano ndi magetsi malinga ndi nthawi yeniyeni ya batri, kuwonetsetsa kuti kulipiritsa kotetezeka komanso kothandiza.

Mfundo Yogwirira Ntchito

Mfundo yogwirira ntchito ya mulu wolipiritsa wa DC imakhudzanso zinthu zitatu: kutembenuza mphamvu, kuwongolera kwapano ndi kasamalidwe kakulumikizana:
Kusintha mphamvu:Mulu wolipiritsa wa DC umayenera kusintha mphamvu ya AC kukhala mphamvu ya DC, yomwe imazindikiridwa ndi chowongolera chamkati. Wokonzanso nthawi zambiri amatenga chozungulira chowongolera mlatho, chomwe chimakhala ndi ma diode anayi, ndipo amatha kusintha magawo oyipa ndi abwino a mphamvu ya AC kukhala mphamvu ya DC motsatana.
Ulamuliro wapano:Ma charger a DC amayenera kuwongolera pakali pano kuti atsimikizire chitetezo komanso kuchita bwino pakulipiritsa. Kuwongolera kwapano kumazindikiridwa ndi wowongolera omwe ali mkati mwa mulu wothamangitsa, omwe amatha kusintha mwamphamvu kukula kwapakali pano malinga ndi kufunikira kwa galimoto yamagetsi komanso kuchuluka kwa mulu wothamangitsa.
Kasamalidwe kakulumikizana:Milu yolipiritsa ya DC nthawi zambiri imakhala ndi ntchito yolumikizirana ndi galimoto yamagetsi kuti izindikire kasamalidwe ndi kuwunika momwe kulipiritsa. Kuwongolera kulumikizana kumakwaniritsidwa kudzera mugawo loyankhulirana mkati mwa mulu wothamangitsa, womwe ungathe kulumikizana ndi njira ziwiri ndi galimoto yamagetsi, kuphatikiza kutumiza malamulo othamangitsa kuchokera ku mulu wothamangitsa kupita kugalimoto yamagetsi ndikulandila zidziwitso zamagalimoto amagetsi.

Mphamvu yolipira

Milu yolipiritsa ya DC imadziwika ndi kutha kwamphamvu kwambiri. Pali zosiyanasiyanaMa charger a DCpa msika, kuphatikizapo 40kW, 60kW, 120kW, 160kW ngakhale 240kW. Ma charger amphamvuwa amatha kubweretsanso magalimoto amagetsi mwachangu pakanthawi kochepa, amachepetsa kwambiri nthawi yolipira. Mwachitsanzo, positi yochazira ya DC yokhala ndi mphamvu ya 100kW ingathe, pansi pamikhalidwe yabwino, kulipiritsa batire yagalimoto yamagetsi kuti ikwane mkati mwa theka la ola mpaka ola limodzi. Ukadaulo wapamwamba kwambiri umawonjezeranso mphamvu yolipiritsa kupitilira 200kW, kufupikitsa nthawi yolipiritsa ndikupangitsa kuti ogwiritsa ntchito magalimoto amagetsi azikhala osavuta.

Gulu ndi Kapangidwe

Milu yolipiritsa ya DC imatha kugawidwa mosiyanasiyana, monga kukula kwa mphamvu, kuchuluka kwa mfuti zolipiritsa, mawonekedwe apangidwe ndi njira yoyika.
Mapangidwe a milu yolipirira:Milu yolipiritsa ya DC imatha kugawidwa kukhala mulu wolipiritsa wa DC ndikugawa mulu wolipiritsa wa DC.
Miyezo yolipirira:akhoza kugawidwa mu Chinese muyezo:GB/T; Muyezo waku Europe: IEC (International Electrotechnical Commission); Muyezo wa US: SAE (Society of Automotive Engineers of United States); Japanese Standard: CHAdeMO (Japan).
Magulu amfuti olipira:malinga ndi kuchuluka kwa mfuti za charger za mulu wothamangitsa zitha kugawidwa kukhala mfuti imodzi, mfuti ziwiri, mfuti zitatu, komanso zitha kusinthidwa malinga ndi zomwe mukufuna.
Mapangidwe amkati a positi yolipirira:Gawo lamagetsi laDC positi yolipiraimakhala ndi pulayimale yoyambira ndi yachiwiri. Kulowetsa kwa gawo lalikulu ndi mphamvu ya AC ya magawo atatu, yomwe imasinthidwa kukhala mphamvu ya DC yovomerezeka ku batri ndi gawo lacharging (rectifier module) pambuyo polowetsa chophwanya dera ndi mita yanzeru ya AC, kenako ndikulumikizidwa ndi fuse ndi mfuti ya charger. kulipiritsa galimoto yamagetsi. Dera lachiwiri limakhala ndi chowongolera milu yolipiritsa, owerenga makhadi, skrini yowonetsera, mita ya DC, ndi zina zambiri. Amapereka kuwongolera kwa 'start-stop' ndi ntchito ya 'emergency stop', komanso zida zolumikizirana ndi anthu monga kuwala kwa siginecha ndi skrini yowonetsera. .

Kugwiritsa Ntchito Scenario

DC yopangira miluamagwiritsidwa ntchito kwambiri m'malo osiyanasiyana omwe amafunikira kubwezeretsedwanso mwachangu kwamagetsi chifukwa cha kuthamangitsa kwawo mwachangu. Pazoyendera zapagulu, monga mabasi ammzinda, ma taxi ndi magalimoto ena othamanga kwambiri, magalimoto othamanga kwambiri, mulu wothamangitsa wa DC umapereka njira yodalirika yolipirira mwachangu. M'malo ochitira misewu yayikulu, malo ogulitsira akuluakulu, malo oimika magalimoto a anthu onse ndi malo ena onse, milu yolipiritsa ya DC imaperekanso ntchito zolipiritsa kwa ogwiritsa ntchito magalimoto amagetsi. Kuphatikiza apo, milu yolipiritsa ya DC nthawi zambiri imayikidwa m'malo apadera monga malo osungirako mafakitale ndi malo osungiramo zinthu kuti akwaniritse zosowa zamagalimoto apadera pakiyo. Chifukwa cha kutchuka kwa magalimoto amagetsi atsopano, malo okhalamo ayambanso kukhazikitsa milu yolipiritsa ya DC kuti apereke mwayi wolipiritsa magalimoto amagetsi a anthu okhalamo.

Mawonekedwe

Kuchita bwino kwambiri komanso kuthamanga: Kusintha kwamphamvu kwa mulu wolipiritsa wa DC kumamalizidwa mkati mwa muluwo, kupeŵa kutayika kwa inverter pa board ndikupangitsa kuti kulipiritsa kukhale koyenera. Panthawi imodzimodziyo, mphamvu yowonjezera mphamvu yamagetsi imapangitsa kuti magalimoto amagetsi azitha kuthamangitsidwa mwamsanga pakapita nthawi.
Zogwiritsidwa ntchito kwambiri: Milu yolipiritsa ya DC ndiyoyenera kugwiritsidwa ntchito mosiyanasiyana, kuphatikiza zoyendera za anthu onse, masiteshoni apadera, malo opezeka anthu onse ndi madera okhala, ndi zina zambiri, kuti akwaniritse zosowa za ogwiritsa ntchito osiyanasiyana.
Zanzeru komanso zotetezeka: Milu yoyitanitsa ya DC yokhala ndi makina owongolera anzeru imatha kuyang'anira momwe batire ilili munthawi yeniyeni ndikusinthiratu magawo oyitanitsa kuti atsimikizire chitetezo ndi kukhazikika kwa njira yolipirira.
Limbikitsani kupangidwa kwa magalimoto amagetsi atsopano: kugwiritsa ntchito mulu wothamangitsa wa DC kumathandizira kwambiri kutchuka kwa magalimoto amagetsi atsopano ndikulimbikitsa kukula kwachangu kwamakampani opanga magalimoto amagetsi.
