Electric and plug-in hybrid electric vehicles include a rechargeable traction battery. An automated vehicle charging system is configured to charge the traction battery with minimal operator intervention. The vehicle charging system includes a carousel, including a plurality of transmit coils, configured to move in a longitudinal direction and rotate about an axis. The vehicle charging system further includes at least one controller programmed to move the carousel in the longitudinal direction and rotate the carousel about the axis to align a selected transmit coil from the plurality of transmit coils with a vehicle receive coil. The vehicle charging system may receive positioning data from a vehicle and may move and rotate the carousel according to the positioning data to align the selected transmit coil with the vehicle receive coil.
