Nrog rau kev loj hlob sai ntawm EV kev lag luam, DC charging pawg tau dhau los ua ib feem tseem ceeb ntawm EV charging infrastructure vim lawv tus yam ntxwv, thiab qhov tseem ceeb ntawm cov chaw them nqi DC tau dhau los ua qhov tseem ceeb. Piv rau AC charging pawg,DC charging pawgmuaj peev xwm muab DC lub zog ncaj qha rau EV roj teeb, txo qis lub sijhawm them thiab feem ntau them txog 80 feem pua hauv tsawg dua 30 feeb. Txoj kev them nyiaj npaum no ua rau nws siv ntau duaAC charging pawgnyob rau hauv cov chaw xws li cov chaw them nqi pej xeem, cov chaw lag luam thiab cov chaw pabcuam kev loj.
Nyob rau hauv cov nqe lus ntawm cov txheej txheem, DC them pawg feem ntau paub txog kev hloov hluav taws xob hluav taws xob los ntawm kev hloov hluav taws xob ntau zaus thiab lub zog hluav taws xob. Nws cov qauv sab hauv suav nrog rectifier, lim thiab tswj qhov system kom muaj kev ruaj ntseg thiab kev nyab xeeb ntawm cov zis tam sim no. Meanwhile, lub ntse nta ntawmDC charging pawgtau maj mam txhim kho, thiab ntau yam khoom tau nruab nrog kev sib txuas lus sib txuas uas ua kom cov ntaub ntawv sib cuam tshuam nrog EVs thiab cov phiaj xwm hluav taws xob kom ua kom zoo dua cov txheej txheem them nqi thiab kev tswj hwm kev siv hluav taws xob. Nws cov txheej txheem technical profile feem ntau suav nrog cov hauv qab no:
1. Rectification txheej txheem: DC charging pawg muaj built-in rectifiers kom ua tiav kev them nyiaj los ntawm kev hloov AC zog rau DC lub zog. Cov txheej txheem no suav nrog kev sib koom ua haujlwm ntawm ntau lub diodes los hloov qhov zoo thiab qhov tsis zoo ib nrab lub lis piam ntawm AC rau DC.
2. Lim thiab Voltage Regulation: Lub zog DC hloov dua siab tshiab yog smoothed los ntawm lub lim kom tshem tawm cov kev hloov pauv tam sim no thiab xyuas kom muaj kev ruaj ntseg ntawm cov zis tam sim no. Tsis tas li ntawd, tus tswj hluav taws xob yuav tswj cov hluav taws xob kom ntseeg tau tias qhov hluav taws xob ib txwm nyob hauv qhov chaw nyab xeeb thaum lub sijhawm them nyiaj.
3. Intelligent tswj system: Niaj hnub nimno DC charging pawg yog nruab nrog lub ntse tswj system uas saib xyuas cov nqi them raws sijhawm thiab hloov pauv hloov pauv tam sim no thiab qhov hluav taws xob txhawm rau txhim kho kev them nqi thiab tiv thaiv lub roj teeb kom siab tshaj plaws.
4. Kev sib txuas lus raws tu qauv: Kev sib txuas lus ntawm DC chargers thiab EVs feem ntau yog ua raws li cov txheej txheem kev cai xws li IEC 61850 thiab ISO 15118, uas tso cai rau kev sib pauv cov ntaub ntawv ntawm lub charger thiab lub tsheb, ua kom muaj kev nyab xeeb thiab ua haujlwm ntawm cov txheej txheem them nyiaj.
Hais txog kev them nyiaj tshaj tawm cov qauv khoom, DC cov ntawv tshaj tawm ua raws li cov qauv thoob ntiaj teb thiab lub teb chaws kom muaj kev nyab xeeb thiab ua tau zoo. IEC 61851 tus qauv muab los ntawm International Electrotechnical Commission (IEC) muab kev taw qhia txog kev sib txuas ntawm EVs thiab cov chaw them nqi, suav nrog kev sib txuas hluav taws xob thiab kev sib txuas lus. Suav tebGB/T 20234 tus qauv, ntawm qhov tod tes, qhia meej cov kev cai thiab kev nyab xeeb tshwj xeeb rau kev them cov pawg. Tag nrho cov qauv no tswj cov qauv ntawm cov khoom siv hluav taws xob thiab tsim kev lag luam rau qee qhov, thiab rau qee qhov, pab txhawb kev noj qab haus huv ntawm kev lag luam rau lub zog tshiab hluav taws xob tsheb thiab lawv cov kev lag luam txhawb nqa.
Hais txog hom phom phom ntawm DC charging pawg, DC charging pawg tuaj yeem muab faib ua ib rab phom, ob rab phom thiab ntau rab phom them pawg. Ib rab phom charging pawg yog tsim rau cov chaw them me me, thaum rab phom dual thiab ntau rab phom charging pawg yog tsim rau thaj chaw loj kom tau raws li qhov xav tau ntau dua. Cov ntawv tshaj tawm ntau phom yog nrov heev vim tias lawv tuaj yeem ua haujlwm rau ntau lub EVs tib lub sijhawm, ua rau kom them nyiaj ntau dua.
Thaum kawg, muaj kev pom zoo rau kev ua lag luam them nyiaj: yav tom ntej ntawm DC charging pawg yog paub tseeb tias yuav muaj peev xwm ua tiav raws li kev siv thev naus laus zis thiab kev lag luam xav tau loj hlob. Kev sib xyaw ua ke ntawm cov phiaj xwm ntse, tsheb tsis muaj tsheb thiab lub zog txuas ntxiv yuav ua rau lub sijhawm tshiab uas tsis tau muaj dua los rau DC charging pawg. Los ntawm kev txhim kho ntxiv ntawm lub sijhawm ntsuab, peb ntseeg tias DC charging pawg yuav tsis tsuas yog muab cov neeg siv nrog kev paub yooj yim dua, tab sis tseem yuav pab txhawb kev txhim kho kom ruaj khov ntawm tag nrho e-mobility ecosystem.
Yog tias koj xav paub ntau ntxiv txog kev pab tswv yim them nqi chaw nres tsheb, koj tuaj yeem nyem rau ntawm:Coj koj nkag siab ntau ntxiv ntawm cov khoom lag luam tshiab - AC them pawg
