Nanga bwanji DC kulipiritsa kapenaKuthamanga kwa DC mwachangukwa magalimoto amagetsi?Mubulogu iyi tiphunzira za zinthu zitatu: Choyamba, ndi zigawo ziti zazikulu za charger ya DC.Chachiwiri, ndi zolumikizira zamtundu wanji zomwe zimagwiritsidwa ntchito pakulipiritsa kwa DC ndipo chachitatu ndi malire otani pa kulipiritsa mwachangu kwa DC.
Kodi gawo lofunikira pakulipiritsa kwa DC ndi chiyani?
Choyamba tiyeni tiwone mbali zazikulu za charger ya DC.Ma charger othamanga a DCNthawi zambiri zimagwira ntchito pamlingo wa mphamvu zitatu zolipiritsa ndipo zidapangidwa kuti zizilipiritsa ma vector amagetsi mwachangu, zotulutsa magetsi kuyambira 50 kilowatts mpaka 350 kilowatts, zokhala ndi mphamvu yayikulu yosinthira ac mpaka DC converter.Chosinthira cha DC kupita ku DC ndi mabwalo owongolera mphamvu amakula komanso okwera mtengo kwambiri, ndichifukwa chake ma charger othamanga a DC amakhazikitsidwa ngati ma charger okakamiza m'malo mongogula okha.Kotero kuti sichitenga malo mkati mwa galimoto ndipo chojambulira chofulumira chikhoza kugawidwa ndi ogwiritsa ntchito ambiri.
Tsopano tiyeni tiwunikenso mayendedwe amagetsi a DC kucharger kuchokera pa charger ya DC kupita ku batire yagalimoto yamagetsi.Pachiyambi choyamba, mphamvu zosinthira zamakono kapena za AC zoperekedwa ndi gridi ya AC zimasinthidwa kukhala zachindunji kapenaDC mphamvupogwiritsa ntchito chowongolera mkati mwa DC chojambulira.Kenako gawo lowongolera mphamvu limasintha moyenerera ma voliyumu ndi apano a chosinthira cha DC kuti chiwongolere mphamvu ya DC yomwe imaperekedwa kuti ipereke batire.
Pali zotchingira chitetezo ndi mabwalo oteteza omwe amagwiritsidwa ntchito kuti achepetse mphamvu cholumikizira cha av ndikuyimitsa kuyimitsa.Nthawi zonse pakakhala vuto kapena kulumikizana kolakwika pakati pa ev ndi charger makina owongolera batire kapena ma bms amakhala ndi gawo lalikulu lakulankhulana pakati pa poyatsira ndikuwongolera mphamvu yamagetsi ndi zomwe zimaperekedwa ku batri ndikuyendetsa dera lodzitchinjiriza. vuto lachitetezo.Mwachitsanzo, netiweki yoyang'anira posachedwapa imanena za sikeni kapena kulumikizana kwa chingwe chamagetsi posachedwa kumatanthawuza kuti plc amagwiritsidwa ntchito polumikizirana pakati pa ev ndi charger popeza tsopano muli ndi lingaliro la momwe charger ya DC imapangidwira.Kenako tiyeni tiwone mitundu yayikulu yolumikizira ma charger a DC pali mitundu isanu ya zolumikizira zamagetsi za DC zomwe zimagwiritsidwa ntchito padziko lonse lapansi.
Ndi zolumikizira zamtundu wanji zomwe zimagwiritsidwa ntchito pakuyitanitsa DC?
Choyamba ndi ma ccs kapena makina opangira ophatikiza otchedwa combo one cholumikizira chomwe chimagwiritsidwa ntchito makamaka mwa ife Chachiwiri ndi cholumikizira cha ccs combo 2 chomwe chimagwiritsidwa ntchito makamaka ku Europe.Chachitatu ndi cholumikizira chachiwonetsero cha asha chomwe chimagwiritsidwa ntchito padziko lonse lapansi pamagalimoto opangidwa ndi opanga aku Japan, makamaka chachinayi cholumikizira cha ds tesla DC chomwe chimagwiritsidwanso ntchito polipiritsa ma ac ndipo pomaliza China ili ndi cholumikizira chake cha DC kutengera mulingo wa gbt wakuchinese.
Tiyeni tsopano tiyang'ane zolumikizira izi imodzi ndi imodzi makina ophatikizira othamangitsira kapena zolumikizira za ccs zimatchedwanso combo r integral integrated zolumikizira zonse za ma AC ndi DC zomwe zimachokera ku zolumikizira zamtundu 1 ndi mtundu 2 zolumikizira ma ac powonjezera mapini awiri owonjezera pa. m'munsi kuti muthamangitse DC wamakono.Zolumikizira zomwe zimachokera ku mtundu 1 ndi mtundu 2 zimatchedwa combo 1 ndi combo 2.
Choyamba tiyeni tiwone cholumikizira cha ccs combo 1 mu slide iyi, galimoto ya combo 1 yolumikizidwa ikuwonetsedwa kumanzere ndipo cholowera chagalimoto chikuwonetsedwa kumanja, cholumikizira chagalimoto cha combo 1 chimachokera ku cholumikizira cha ac 1. ndipo imasunga pini yapadziko lapansi ndi zikhomo za 2 zomwe ndi woyendetsa ndege komanso woyendetsa pafupi ndi DC mapini amawonjezedwa kuti azilipiritsa mofulumira pansi pa cholumikizira.
Pamalo olowera apini masinthidwe a pini mbali yakumtunda yofanana ndi cholumikizira cha ac type 1 cha ac charging pomwe mapini 2 apansi amagwiritsidwa ntchito polipira DC chimodzimodzi.Ma ccs combo awiri olumikizira amachokera ku zolumikizira zamtundu wa ac ndikusunga pini yapadziko lapansi ndipo zikhomo ziwiri zolumikizira zomwe ndi woyendetsa woyendetsa moyandikira pafupi ndi ma pini amagetsi a DC amawonjezedwa pansi pa cholumikizira champhamvu champhamvu cha DC cholipiritsa chimodzimodzi. .
Pagalimoto yomwe ili mbali imeneyo kumtunda kumathandizira kuthamangitsa ma ac kuchokera pamagawo atatu ac ndi pansi.Muli ndi kuyitanitsa kwa DC mosiyana ndi mtundu wa 1 ndi zolumikizira zamtundu wa 2 zomwe zimagwiritsa ntchito kusinthasintha kwa pulse m'lifupi kapena siginecha ya pwm pa woyendetsa ndege yolumikizirana yamagetsi ya plc imagwiritsidwa ntchito ponse pawiri mu combo 1 ndi combo 2 charger ndipo izi zimapangidwira pakuwongolera. .
Kuyankhulana kwa chingwe chamagetsi ndi ukadaulo womwe umanyamula zidziwitso zolumikizirana pazingwe zamagetsi zomwe zimagwiritsidwa ntchito posamutsa nthawi imodzi ma siginecha ndi kutumizira mphamvu ma ccs combo charger amatha kupereka mpaka 350 amps pamagetsi apakati pa 200 mpaka 1000 volts.Kupereka mphamvu yochuluka yotulutsa ma kilowatts 350 ziyenera kukumbukiridwa kuti zikhalidwezi zimasinthidwa mosalekeza ndi miyezo yolipiritsa kuti ikwaniritse zofunikira zamagetsi ndi mphamvu zamagalimoto atsopano amagetsi.Mtundu wachitatu wa charger wa DC ndi cholumikizira mthunzi chomwe ndi cholumikizira chamtundu wa 4 eb chili ndi mapini atatu amphamvu ndi mapini asanu ndi limodzi opangira ntchitoyi.The shidae moe amagwiritsa ntchito network network network kapena kin protocol mu zikhomo zolumikizirana polumikizana.
Pakati pa charger ndi galimoto malo owongolera maukonde kulumikizana ndi njira yolumikizirana yamagalimoto yolimba imasankha kulola ma microcontrollers ndi zida kuti zizilumikizana munthawi yeniyeni.Popanda makompyuta omwe ali nawo panopa, mphamvu zamagetsi ndi zamakono ndi mphamvu za shada moe zikuchokera ku 50 mpaka 400 volts ndi zamakono mpaka 400 amps motero zimapereka mphamvu yapamwamba yofikira ma kilowatts 200 kuti azilipiritsa mtsogolo.
Zikuyembekezeka kuti eb kuyitanitsa mpaka 1,000 volts ndi 400 kilowatts ithandizidwa ndi demo tsopano.Tiyeni tipitirire ku zolumikizira ma charger a tesla, network ya tesla supercharger ku United States imagwiritsa ntchito cholumikizira cha charger yawoyawo pomwe mitundu yaku Europe imagwiritsa ntchito cholumikizira chamtundu wa 2 minoccurs koma chojambulira cha DC chomangidwa mu gawo lapadera la cholumikizira cha tesla ndi cholumikizira chomwecho. itha kugwiritsidwa ntchito pa ma ac charging ndi DC charging tesla tsopano.Imapereka DC yolipira mpaka ma kilowatts 120 ndipo izi zikuyembekezeka kuwonjezeka mtsogolo.
Kodi malire a DC Fast Charging ndi ati?
Pomaliza, China ili ndi mulingo watsopano wa charger wa DC ndi cholumikizira chomwe chimagwiritsa ntchito netiweki yowongolera mabasi.Basi imabwera kuti ilankhule ili ndi ma pini asanu amagetsi awiri amagetsi a DC ndi awiri amagetsi ocheperako owonjezera mphamvu ndi imodzi yapansi ndipo ili ndi ma pini anayi a siginecha awiri kwa woyendetsa moyandikana ndi awiri olumikizirana ndi malo ochezera.Pofika pano, magetsi omwe amagwiritsidwa ntchito polumikizira ichi kapena 750 volts kapena 1000 volts ndipo pano mpaka 250 amps amathandizidwa ndi charger iyi.Imatha kuwona kale kuthamangitsa mwachangu ndi kokongola chifukwa champhamvu zolipiritsa kwambiri mpaka 300 kapena 400 kilowatts.
Izi zimapangitsa kuti pakhale nthawi yayifupi kwambiri yolipiritsa koma mphamvu yothamangitsa mwachangu siyingawonjezeke mpaka kalekale, izi zimachitika chifukwa cha zolephera zitatu zaukadaulo pakuthamangitsa mwachangu.Tiyeni tsopano tiyang'ane zolepheretsa izi, choyamba, kuyitanitsa kwaposachedwa kwambiri kumabweretsa kuwonongeka kwakukulu mu charger ndi batire.
Mwachitsanzo, ngati kukana kwamkati kwa batri ndi r ndipo zotayika mu batri zitha kuwonetsedwa pogwiritsa ntchito fomula i squared r pomwe ndimalipiritsa ndiye mudzazindikira kuti zotayikazo zidawonjezeka kangapo kanayi.Nthawi zonse, mphamvu yamagetsi imawirikizidwa kawiri kachiwiri, malire achiwiri akuchokera ku batri pamene mukuyitanitsa batire koyamba.Kukwera kwa batri kumatha kukwera mpaka 70 mpaka 80% chifukwa kuyitanitsa mwachangu kumapangitsa kuti pakhale kutsika pakati pa voteji ndi momwe amapangira.
Chodabwitsa ichi chikuwonjezeka pa batire ndi kulipiritsidwa mofulumira choncho.Kuyitanitsa koyamba kumachitika nthawi zonse pakali pano kapena m'dera la cc la kulipiritsa batire ndipo pambuyo pake.Mphamvu yolipiritsa imachepetsedwa pang'onopang'ono m'dera lamagetsi lamagetsi kapena ma cv komanso kuchuluka kwa mabatire kapena kuchuluka kwa c kumawonjezeka ndikuthamangitsa mwachangu ndipo izi zimabweretsa kuchepa kwa moyo wa batri.
Kuletsa kwachitatu kukuchokera pachingwe chojambulira chachaja chilichonse cha evie ndikofunikira kuti chingwecho chikhale chosinthika komanso chopepuka.Chifukwa chake anthu atha kunyamula chingwecho ndikuchilumikiza kugalimoto yokhala ndi mphamvu zochapira zokulirapo ndipo zingwe zokhuthala zimafunika kuti pakhale magetsi ochulukira, apo ayi chitha kutentha.Chifukwa cha zotayika makina othamangitsira a DC masiku ano amatha kutumiza mafunde othamangitsa mpaka 250 amperes popanda kuziziritsa.
Komabe, mtsogolomu ndi mafunde pafupifupi 250 amp ere zingwe zolipiritsa zitha kukhala zolemera kwambiri komanso zosasinthika kuti zigwiritsidwe ntchito.Njira yothetsera vutoli ingakhale kugwiritsa ntchito zingwe zocheperako pakalipano zomwe zili ndi makina ozizirira omangidwa mkati ndi kasamalidwe ka matenthedwe kuti zingwe sizitenthe.Zachidziwikire, zovuta komanso zotsika mtengo kuposa kugwiritsa ntchito chingwe popanda kuziziritsa, kotero kuti titseke bulogu iyi mubulogu iyi tidawona magawo ofunikira a DC kapena chojambulira chaposachedwa kwambiri tidayang'ananso mitundu yosiyanasiyana ya zolumikizira za DC.
