As the energy replenishment device for electric vehicles, the charging performance of EV charging stations affects battery pack lifespan and charging time.
DC charging stations deliver direct current to vehicles. They draw grid power (three-phase AC) externally, convert AC to DC through rectification within the station, and transmit DC electricity of specified magnitude and power to vehicle batteries under the coordination of the control center and its components.
Electric vehicle wireless charging technology transmits energy via high-frequency alternating magnetic fields from underground power supply rails to vehicle-mounted energy pickup mechanisms within a certain range above ground. This powers onboard energy storage devices, enabling EVs to carry fewer battery packs while extending range. Energy replenishment becomes safer and more convenient.
Key technical parameters for dynamic wireless power transfer include: power transfer distance,power rating,efficiency,lateral misalignment tolerance of coupling mechanism,and electromagnetic compatibility (EMC).
