Nrog rau kev loj hlob ntawm kev lag luam tshiab lub zog tsheb, DC them pawg, raws li qhov chaw tseem ceeb rau kev them nqi hluav taws xob sai, yog maj mam tuav txoj haujlwm tseem ceeb hauv kev ua lag luam, thiabBeiHai zog(Tuam Tshoj), raws li ib tug tswv cuab ntawm lub zog tshiab, kuj tseem ua haujlwm tseem ceeb rau kev nyiam thiab txhawb zog tshiab. Nyob rau hauv tsab xov xwm no, peb yuav piav qhia txog DC charging pawg nyob rau hauv cov nqe lus ntawm daim ntawv thov technology, ua hauj lwm hauv paus ntsiab lus, them hwj chim, kev faib cov qauv, kev siv scenarios thiab cov yam ntxwv.
Kev siv tshuab
DC charging pawg (hu ua DC charging pawg) txais cov cuab yeej siv hluav taws xob siab tshaj plaws, thiab nws cov tub ntxhais nyob hauv lub inverter sab hauv. Lub hauv paus ntawm lub inverter yog lub hauv paus inverter, uas tuaj yeem hloov pauv AC lub zog los ntawm daim phiaj hluav taws xob mus rau DC lub zog thiab muab nws ncaj qha rau lub roj teeb ntawm lub tsheb fais fab rau kev them nyiaj. Cov txheej txheem hloov dua siab tshiab no yog ua tiav hauv cov ntawv tshaj tawm them nyiaj, zam qhov poob ntawm lub zog hloov pauv los ntawm EV on-board inverter, uas ua rau muaj txiaj ntsig zoo rau kev them nqi. Tsis tas li ntawd, DC charging ncej yog nruab nrog cov kev tswj xyuas ntse uas tau hloov kho cov nqi them tam sim no thiab qhov hluav taws xob raws li lub sijhawm tiag tiag ntawm lub roj teeb, ua kom muaj kev nyab xeeb thiab siv tau zoo.
Txoj Cai Ua Haujlwm
Lub hauv paus ntsiab lus ua haujlwm ntawm DC charging pawg feem ntau suav nrog peb yam: kev hloov hluav taws xob, kev tswj tam sim no thiab kev sib txuas lus:
Hloov lub zog:DC charging pawg thawj zaug yuav tsum tau hloov AC lub zog rau DC lub zog, uas yog pom tau los ntawm lub rectifier sab hauv. Lub rectifier feem ntau txais yuav ib lub voj voog rectifier, uas yog tsim los ntawm plaub lub diodes, thiab tuaj yeem hloov qhov tsis zoo thiab qhov zoo ntawm AC lub zog rau hauv DC lub zog raws li.
Kev tswj tam sim no:DC chargers yuav tsum tswj cov nqi them tam sim no kom muaj kev nyab xeeb thiab ua haujlwm ntawm cov txheej txheem them. Kev tswj tam sim no tau paub los ntawm tus tswj hwm kev them nyiaj hauv pawg them nyiaj, uas tuaj yeem hloov kho qhov loj ntawm qhov them tam sim no raws li qhov xav tau ntawm lub tsheb hluav taws xob thiab lub peev xwm ntawm pawg them nyiaj.
Kev tswj hwm kev sib txuas lus:DC charging pawg feem ntau kuj muaj qhov ua haujlwm ntawm kev sib txuas lus nrog lub tsheb hluav taws xob kom paub txog kev tswj hwm thiab saib xyuas cov txheej txheem them nyiaj. Kev tswj hwm kev sib txuas lus tau pom zoo los ntawm kev sib txuas lus hauv pawg them nyiaj, uas tuaj yeem nqa ob txoj kev sib txuas lus nrog lub tsheb hluav taws xob, suav nrog xa cov lus txib them los ntawm pawg them rau lub tsheb hluav taws xob thiab tau txais cov ntaub ntawv xwm txheej ntawm lub tsheb hluav taws xob.
Them fais fab
DC charging pawg paub txog lawv lub peev xwm them hluav taws xob siab. Muaj ntau yamDC chargersntawm kev ua lag luam, suav nrog 40kW, 60kW, 120kW, 160kW thiab txawm tias 240kW. Cov khoom siv hluav taws xob siab no tuaj yeem ua kom cov tsheb hluav taws xob sai sai hauv lub sijhawm luv luv, txo lub sijhawm them nyiaj ntau. Piv txwv li, DC charging ncej nrog lub zog ntawm 100kW tuaj yeem, nyob rau hauv cov xwm txheej zoo, them lub tsheb hluav taws xob lub roj teeb kom muaj peev xwm li ib nrab teev mus rau ib teev. Lub tshuab thev naus laus zis tseem ua rau kom lub zog them ntau dua 200kW, ntxiv kom luv lub sijhawm them thiab ua kom yooj yim rau cov neeg siv tsheb fais fab.
Classification thiab Structure
DC charging pawg tuaj yeem raug cais los ntawm qhov sib txawv, xws li lub zog loj, tus naj npawb ntawm cov phom them, cov qauv qauv thiab cov txheej txheem kev teeb tsa.
Charging pawg qauv:DC charging pawg tuaj yeem muab faib ua DC charging pawg thiab faib DC them pawg.
Cov txheej txheem them cov khoom siv:tuaj yeem muab faib ua Suav tus qauv:GB / T; European txheem: IEC (Lub International Electrotechnical Commission); US tus qauv: SAE (Society of Automotive Engineers of United States); Japanese Standard: CHAdeMO (Nyiv).
Charging phom classification:raws li tus naj npawb ntawm cov phom charger ntawm lub charger pawg tuaj yeem muab faib ua ib rab phom, ob rab phom, peb rab phom, thiab tseem tuaj yeem kho raws li qhov xav tau tiag tiag.
Internal qauv muaj pes tsawg leeg ntawm charging ncej:Qhov hluav taws xob ntawmDC charging ncejmuaj cov thawj Circuit Court thiab Secondary Circuit Court. Lub tswv yim ntawm lub ntsiab Circuit Court yog peb-theem AC lub zog, uas yog hloov mus rau DC lub zog siv tau rau lub roj teeb los ntawm kev them nyiaj module (rectifier module) tom qab nkag mus rau lub Circuit Court breaker thiab AC smart meter, thiab tom qab ntawd txuas nrog lub fuse thiab charger phom kom them lub tsheb fais fab. Qhov thib ob Circuit Court muaj xws li them pawg tswj hwm, daim npav nyeem ntawv, lub vijtsam zaub, DC meter, thiab lwm yam. Nws muab 'pib-stop' tswj thiab 'tawm xwm txheej ceev' ua haujlwm, nrog rau tib neeg-tshuab sib cuam tshuam cov cuab yeej xws li teeb liab teeb liab thiab zaub screen.
Kev siv Scenario
DC charging pawgyog dav siv nyob rau hauv ntau qhov chaw uas yuav tsum tau ceev replenishment ntawm hluav taws xob vim lawv ceev ceev cov yam ntxwv. Hauv kev thauj mus los rau pej xeem, xws li tsheb npav hauv nroog, tsheb tavxij thiab lwm yam kev ua haujlwm siab, tsheb khiav ceev, DC charging pawg muab kev daws teeb meem ceev ceev. Hauv cov chaw pabcuam kev loj, cov khw loj loj, cov chaw nres tsheb pej xeem thiab lwm qhov chaw pej xeem, DC charging pawg kuj muab cov kev pabcuam them nqi yooj yim rau cov neeg siv tsheb thauj khoom. Tsis tas li ntawd, DC charging pawg feem ntau tau teeb tsa ntawm cov chaw tshwj xeeb xws li cov chaw ua haujlwm hauv chaw ua haujlwm thiab chaw ua haujlwm logistics kom tau raws li cov kev xav tau ntawm cov tsheb tshwj xeeb hauv lub tiaj ua si. Nrog rau qhov nrov ntawm lub zog tshiab tsheb, cov neeg nyob ib puag ncig tau maj mam pib nruab DC charging pawg los muab kev yooj yim them nyiaj rau cov neeg nyob hauv lub tsheb hluav taws xob.
Nta
Kev ua haujlwm siab thiab ceev: Lub zog hloov pauv ntawm DC charging pawg ua tiav nyob rau hauv pawg, tsis txhob poob ntawm on-board inverter thiab ua kom them nyiaj ntau dua. Nyob rau tib lub sijhawm, lub peev xwm them hluav taws xob muaj peev xwm ua rau lub tsheb hluav taws xob tau nrawm dua hauv lub sijhawm luv luv.
Muaj feem xyuam: DC charging pawg yog tsim rau ntau yam kev siv, nrog rau kev thauj mus los rau pej xeem, chaw nres tsheb tshwj xeeb, cov chaw pej xeem thiab cov zej zog nyob, thiab lwm yam, kom tau raws li cov kev xav tau ntawm cov neeg siv sib txawv.
Kev txawj ntse thiab kev nyab xeeb: DC charging pawg nruab nrog cov kev tswj xyuas ntse tuaj yeem saib xyuas cov roj teeb hauv lub sijhawm tiag tiag thiab hloov kho cov nqi them nyiaj kom ntseeg tau tias muaj kev nyab xeeb thiab ruaj khov ntawm cov txheej txheem them nyiaj.
Txhawb txoj kev loj hlob ntawm lub zog tshiab tsheb: daim ntawv thov dav ntawm DC charging pawg muab kev txhawb zog rau cov koob npe ntawm lub zog tshiab tsheb thiab txhawb txoj kev loj hlob sai ntawm kev lag luam tsheb tshiab.
