Ndi chitukuko cha makampani atsopano amagetsi, DC charging pile, monga malo ofunikira kwambiri pakuchaja magalimoto amagetsi mwachangu, pang'onopang'ono ikutenga malo ofunikira pamsika, ndipoMphamvu ya BeiHai(China), monga membala wa gawo latsopano la mphamvu, ikuperekanso zopereka zofunika pakufalitsa ndi kukweza mphamvu zatsopano. M'nkhaniyi, tifotokoza mwatsatanetsatane za milu ya DC yochapira malinga ndi ukadaulo wogwiritsira ntchito, mfundo yogwirira ntchito, mphamvu yochapira, kapangidwe ka magulu, zochitika zogwiritsira ntchito ndi makhalidwe ake.
Kugwiritsa ntchito ukadaulo
Mulu wochapira wa DC (wotchedwa mulu wochapira wa DC) umagwiritsa ntchito ukadaulo wapamwamba wamagetsi, ndipo pakati pake pali inverter yamkati. Pakati pa inverter ndi inverter yamkati, yomwe imatha kusintha bwino mphamvu ya AC kuchokera ku gridi yamagetsi kukhala mphamvu ya DC ndikuyipereka mwachindunji ku batire yagalimoto yamagetsi kuti ijayidwe. Njira yosinthirayi imachitika mkati mwa positi yochapira, kupewa kutayika kwa kusintha kwa mphamvu ndi inverter yamagetsi yomwe ili m'bwalo, zomwe zimapangitsa kuti ntchito yochapira ikhale yabwino kwambiri. Kuphatikiza apo, positi yochapira ya DC ili ndi njira yowongolera yanzeru yomwe imasintha yokha mphamvu yamagetsi ndi magetsi malinga ndi momwe batire ilili nthawi yeniyeni, kuonetsetsa kuti njira yochapira ili yotetezeka komanso yothandiza.
Mfundo Yogwirira Ntchito
Mfundo yogwirira ntchito ya DC charging mulu makamaka imakhudza mbali zitatu: kusintha kwa mphamvu, kuwongolera kwamakono ndi kasamalidwe ka kulumikizana:
Kusintha kwa mphamvu:Choyamba, DC charging pile imafunika kusintha mphamvu ya AC kukhala mphamvu ya DC, yomwe imachitika ndi rectifier yamkati. Rectifier nthawi zambiri imagwiritsa ntchito bridge rectifier circuit, yomwe imapangidwa ndi ma diode anayi, ndipo imatha kusintha magawo awiri olakwika ndi abwino a mphamvu ya AC kukhala mphamvu ya DC motsatana.
Kulamulira kwamakono:Ma charger a DC ayenera kulamulira mphamvu yochajira kuti atsimikizire chitetezo ndi magwiridwe antchito a njira yochajira. Kulamulira kwa mphamvu kumachitika ndi chowongolera cha chaji mkati mwa mulu wochajira, chomwe chingathe kusintha kukula kwa mphamvu yochajira malinga ndi kufunikira kwa galimoto yamagetsi komanso mphamvu ya mulu wochajira.
Kuwongolera kulumikizana:Ma DC charging piles nthawi zambiri amakhala ndi ntchito yolankhulana ndi galimoto yamagetsi kuti akwaniritse kayendetsedwe ndi kuyang'anira njira yochajira. Kuwongolera kulumikizana kumachitika kudzera mu gawo lolumikizirana mkati mwa mulu wa charging, lomwe limatha kulumikizana mbali ziwiri ndi galimoto yamagetsi, kuphatikiza kutumiza malamulo ochajira kuchokera mu mulu wa charging kupita ku galimoto yamagetsi ndikulandira zambiri za momwe galimoto yamagetsi ilili.
Mphamvu yolipiritsa
Ma DC charging piles amadziwika ndi mphamvu yawo yochaja yamphamvu kwambiri. Pali mitundu yosiyanasiyana yaMa charger a DCpamsika, kuphatikizapo 40kW, 60kW, 120kW, 160kW komanso 240kW. Ma charger amphamvu awa amatha kudzaza magalimoto amagetsi mwachangu munthawi yochepa, zomwe zimachepetsa kwambiri nthawi yochaja. Mwachitsanzo, positi yochaja ya DC yokhala ndi mphamvu ya 100kW, pansi pa mikhalidwe yabwino, imatha kuchaja batri yagalimoto yamagetsi mpaka mphamvu yonse mkati mwa theka la ola mpaka ola limodzi. Ukadaulo wa supercharging umawonjezera mphamvu yochaja mpaka 200kW, zomwe zimapangitsa kuti nthawi yochaja ichepe komanso kupangitsa kuti ogwiritsa ntchito magalimoto amagetsi akhale osavuta kugwiritsa ntchito.
Kugawa ndi Kapangidwe
Ma DC charging piles amatha kugawidwa m'magulu osiyanasiyana, monga kukula kwa mphamvu, kuchuluka kwa mfuti zochapira, kapangidwe kake ndi njira yoyikira.
Kapangidwe ka mulu wolipiritsa:Ma DC charging piles amatha kugawidwa m'magulu awiri: DC charging piles ndi DC charging piles.
Miyezo ya malo ochapira:akhoza kugawidwa mu muyezo wa Chitchaina:GB/TMuyezo wa ku Ulaya: IEC (International Electrotechnical Commission); Muyezo wa ku US: SAE (Society of Automotive Engineers of United States); Muyezo wa ku Japan: CHAdeMO (Japan).
Gulu la mfuti zolipiritsa:Malinga ndi chiwerengero cha mfuti zochapira, mulu wa mfuti zochapira ukhoza kugawidwa m'magulu awiriawiri, atatu, ndipo ukhoza kusinthidwa malinga ndi kufunika kwenikweni.
Kapangidwe ka mkati ka positi yolipirira:Gawo lamagetsi laChoyimitsa cha DCZimakhala ndi dera loyambira ndi dera lachiwiri. Mphamvu ya dera lalikulu ndi mphamvu ya AC ya magawo atatu, yomwe imasinthidwa kukhala mphamvu ya DC yovomerezeka ndi batri ndi gawo lochajira (module yokonzanso) mutalowetsa chotsegula dera ndi mita yanzeru ya AC, kenako yolumikizidwa ku fuse ndi mfuti yochajira kuti ipereke mphamvu ku galimoto yamagetsi. Dera lachiwiri limakhala ndi chowongolera cha mulu wochajira, chowerengera makadi, chophimba chowonetsera, mita ya DC, ndi zina zotero. Imapereka mphamvu yowongolera 'kuyamba-kusiya' ndi 'kusiya mwadzidzidzi', komanso zida zolumikizirana ndi anthu monga kuwala kwa chizindikiro ndi chophimba chowonetsera.
Chitsanzo Chogwiritsira Ntchito
Ma DC charging pilesamagwiritsidwa ntchito kwambiri m'malo osiyanasiyana omwe amafunikira kubwezeretsanso magetsi mwachangu chifukwa cha mawonekedwe awo ochajira mwachangu. Pankhani ya mayendedwe apagulu, monga mabasi amzinda, ma taxi ndi magalimoto ena othamanga kwambiri, DC charging pile imapereka njira yodalirika yochajira mwachangu. M'malo ochitira ntchito pamsewu waukulu, m'masitolo akuluakulu, m'malo oimika magalimoto apagulu ndi m'malo ena opezeka anthu ambiri, DC charging piles imaperekanso ntchito zosavuta zochajira kwa ogwiritsa ntchito magalimoto amagetsi odutsa. Kuphatikiza apo, DC charging piles nthawi zambiri imayikidwa m'malo apadera monga m'mapaki amakampani ndi m'mapaki oyendetsera zinthu kuti ikwaniritse zosowa za magalimoto apadera m'paki. Chifukwa cha kutchuka kwa magalimoto atsopano amphamvu, madera okhala anthu ayambanso pang'onopang'ono kukhazikitsa DC charging piles kuti apereke mwayi wochajira magalimoto amagetsi a anthu okhalamo.
Mawonekedwe
Kuchita bwino kwambiri komanso liwiro: Kusintha kwa mphamvu ya mulu wa DC charging kumachitika mkati mwa muluwo, kupewa kutayika kwa inverter yomwe ili mkati mwake ndikupangitsa kuti charging ikhale yothandiza kwambiri. Nthawi yomweyo, mphamvu yamphamvu yamagetsi imapangitsa magalimoto amagetsi kuti azitha kubwezeretsedwanso mwachangu pakapita nthawi yochepa.
Zogwiritsidwa ntchito kwambiri: Ma DC charging piles ndi oyenera kugwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikizapo mayendedwe apagulu, masiteshoni apadera, malo opezeka anthu ambiri komanso madera okhala anthu ambiri, ndi zina zotero, kuti akwaniritse zosowa za ogwiritsa ntchito osiyanasiyana zolipirira.
Anzeru komanso otetezeka: Ma pile ochapira a DC okhala ndi makina owongolera anzeru amatha kuyang'anira momwe batire ilili nthawi yeniyeni ndikusintha zokha magawo ochapira kuti atsimikizire chitetezo ndi kukhazikika kwa njira yochapira.
Limbikitsani chitukuko cha magalimoto atsopano amphamvu: kugwiritsa ntchito kwambiri mulu wa DC charging kumathandiza kwambiri kutchuka kwa magalimoto atsopano amphamvu ndipo kumalimbikitsa chitukuko chachangu cha makampani atsopano amagetsi.
