Nrog rau kev loj hlob sai ntawm kev lag luam EV, DC charging piles tau dhau los ua ib feem tseem ceeb ntawm cov khoom siv them EV vim lawv tus kheej cov yam ntxwv, thiab qhov tseem ceeb ntawm DC charging stations tau dhau los ua qhov tseem ceeb. Piv rau AC charging piles,DC charging pilesmuaj peev xwm muab hluav taws xob DC ncaj qha rau cov roj teeb EV, txo lub sijhawm them thiab feem ntau them txog li 80 feem pua hauv tsawg dua 30 feeb. Txoj kev them hluav taws xob zoo no ua rau nws siv dav dua liCov chaw them hluav taws xob ACnyob rau hauv cov chaw xws li cov chaw them roj rau pej xeem, cov chaw lag luam thiab cov chaw pabcuam kev loj.
Hais txog lub hauv paus ntsiab lus, DC charging pile feem ntau ua tiav kev hloov pauv ntawm lub zog hluav taws xob los ntawm kev siv lub zog hloov pauv zaus siab thiab lub zog module. Nws cov qauv sab hauv muaj xws li rectifier, lim thiab tswj system kom ntseeg tau tias muaj kev ruaj khov thiab kev nyab xeeb ntawm cov zis tam sim no. Lub caij no, cov yam ntxwv ntse ntawmDC charging pilesmaj mam txhim kho, thiab ntau yam khoom muaj cov cuab yeej sib txuas lus uas ua rau muaj kev sib cuam tshuam cov ntaub ntawv tiag tiag nrog EVs thiab cov fais fab kom zoo dua cov txheej txheem them thiab kev tswj hwm kev siv hluav taws xob. Nws cov ntsiab cai tseem ceeb suav nrog cov hauv qab no:
1. Cov txheej txheem kho kom raug: DC them cov pawg muaj cov rectifiers ua ke kom ua tiav kev them los ntawm kev hloov AC fais fab mus rau DC fais fab. Cov txheej txheem no cuam tshuam nrog kev ua haujlwm sib koom tes ntawm ntau lub diodes los hloov qhov zoo thiab tsis zoo ib nrab lub lis piam ntawm AC mus rau DC.
2. Kev lim thiab kev tswj hwm qhov hluav taws xob: Lub zog DC hloov pauv tau raug lim kom du los ntawm lub lim kom tshem tawm qhov hloov pauv tam sim no thiab xyuas kom meej tias qhov tso zis tam sim no ruaj khov. Tsis tas li ntawd, lub tshuab tswj qhov hluav taws xob yuav tswj qhov hluav taws xob kom ntseeg tau tias qhov hluav taws xob ib txwm nyob hauv qhov muaj kev nyab xeeb thaum lub sijhawm them.
3. Lub kaw lus tswj hwm ntse: Cov chaw them hluav taws xob DC niaj hnub no muaj lub kaw lus tswj hwm ntse uas saib xyuas qhov xwm txheej them hluav taws xob tiag tiag thiab kho qhov tam sim no thiab qhov hluav taws xob kom zoo tshaj plaws thiab tiv thaiv lub roj teeb kom siab tshaj plaws.
4. Cov txheej txheem sib txuas lus: Kev sib txuas lus ntawm DC chargers thiab EVs feem ntau yog raws li cov txheej txheem txheem xws li IEC 61850 thiab ISO 15118, uas tso cai rau kev sib pauv cov ntaub ntawv ntawm lub charger thiab lub tsheb, kom ntseeg tau tias muaj kev nyab xeeb thiab ua haujlwm tau zoo ntawm cov txheej txheem them.
Hais txog cov qauv khoom siv them hluav taws xob, cov chaw them hluav taws xob DC ua raws li ntau tus qauv thoob ntiaj teb thiab hauv tebchaws kom ntseeg tau tias muaj kev nyab xeeb thiab sib xws. Tus qauv IEC 61851 uas tau muab los ntawm International Electrotechnical Commission (IEC) muab cov lus qhia txog kev sib txuas ntawm EVs thiab cov chaw them hluav taws xob, suav nrog cov khoom siv hluav taws xob thiab cov txheej txheem sib txuas lus. Tuam Tshoj tusGB/T 2023Tus qauv 4, ntawm qhov tod tes, piav qhia txog cov kev cai thiab cov lus qhia txog kev nyab xeeb rau cov pawg them hluav taws xob. Tag nrho cov qauv no tswj hwm cov qauv ntawm kev tsim khoom thiab tsim qauv ntawm pawg them hluav taws xob rau qee qhov, thiab rau qee qhov, pab txhawb kev txhim kho kev noj qab haus huv ntawm kev ua lag luam rau cov tsheb fais fab tshiab thiab lawv cov kev lag luam txhawb nqa.
Hais txog hom phom them ntawm DC charging pile, DC charging pile muaj peev xwm muab faib ua ib rab phom, ob rab phom thiab ntau rab phom. Ib rab phom them pile yog tsim rau cov chaw them me me, thaum ob rab phom thiab ntau rab phom them pile yog tsim rau cov chaw loj dua kom tau raws li qhov xav tau them ntau dua. Cov chaw them ntau rab phom nrov heev vim tias lawv tuaj yeem pabcuam ntau lub tsheb EV tib lub sijhawm, ua rau kev them nqi zoo dua.
Thaum kawg, muaj qhov kev cia siab rau kev lag luam ntawm lub chaw them hluav taws xob: yav tom ntej ntawm DC lub chaw them hluav taws xob yeej yuav muaj peev xwm ntau ntxiv thaum thev naus laus zis nce qib thiab kev thov ntawm kev lag luam loj hlob. Kev sib xyaw ua ke ntawm cov hluav taws xob ntse, tsheb tsis muaj neeg tsav thiab lub zog rov ua dua tshiab yuav coj cov cib fim tshiab tsis tau muaj dua rau DC lub chaw them hluav taws xob. Los ntawm kev txhim kho ntxiv ntawm lub caij nyoog ntsuab, peb ntseeg tias DC lub chaw them hluav taws xob yuav tsis tsuas yog muab kev paub txog kev them hluav taws xob yooj yim dua rau cov neeg siv, tab sis kuj tseem yuav pab txhawb rau kev txhim kho ruaj khov ntawm tag nrho e-mobility ecosystem.
