DC Fast Charging yog dab tsi thiab nws ua haujlwm li cas?
DC Fast Charging (DCFC)yog txoj kev siv hluav taws xob siab uas hloov pauv tam sim no (AC) rauHigh-Voltage Direct Current (DC) nyob rau hauv lub charger unit. Cov chargers no feem ntau ua haujlwm ntawm400V lossis 800V chav kawm voltage theem, xa lub zog los ntawm50 kW txog 350 kW (los yog ntau tshaj), tswj los ntawmIEC 61851-23 tus qauv. DCFCbypasses onboard AC / DC converterthiab pub DC lub zog tam sim no ncaj qha rau EV roj teeb ntawm cov khoom sib txuas tshwj xeeb (xws liCCS, CHAdeMO, or NACS). Tsis tas li ntawd, cov txheej txheem them ceev ceev tau tswj hwm nruj ntawm cov txheej txheem kev sib txuas lus zoo liTS EN ISO 15118 or OCPP (Open Charge Point Protocol)los xyuas kom meej cov ntaub ntawv kev ruaj ntseg thiab zoo them nqi.
Lub hauv paus ntsiab lus ua haujlwm ntawm DC them ceev ceev suav nrog cov khoom siv hluav taws xob ncaj qha mus rau EV lub roj teeb, hla lub tsheb ntawm onboard charger. Qhov kev xa tawm sai ntawm lub zog no ua rau cov tsheb them nqi tsawg li 30 feeb hauv qee kis, ua rau nws zoo tagnrho rau kev taug kev loj thiab qhov chaw uas yuav tsum tau them rov qab sai.
Cov yam ntxwv tseem ceeb los sib tham:
• Hom DC ceev chargers (CHAdeMO, CCS, Tesla Supercharger)
