Abstract:
A vehicle is able to contactlessly receive electric power from a power transmitting device and to charge a mounted electrical storage device (electric load). The vehicle includes a communication unit that carries out wireless communication with the power transmitting device and a vehicle ECU (control unit) that controls the communication unit. The communication unit is able to switch a communication range between a wide communication range (wire-area communication) and a narrow communication range (narrow-area communication). The vehicle ECU, at the time of identifying a power transmitting device from which electric power should be received, controls the communication unit such that the communication unit communicates with the power transmitting device using the narrow-area communication.
