Abstract
A mobile vehicle wirelessly receives AC power from a power transmission device including first and second power transmission electrodes arranged along a road surface. The mobile vehicle includes: a sensor that detects an obstacle located at least either on a route of the mobile vehicle or under the mobile vehicle; a first power reception electrode that forms electric field coupling with the first power transmission electrode when facing the first power transmission electrode; a second power reception electrode that forms electric field coupling with the second power transmission electrode when facing the second power transmission electrode; an actuator that moves at least the part of the first power reception electrode in a direction of gravity; and a control circuit that controls the actuator based on a result of detection by the sensor to avoid contact between the first power reception electrode and the obstacle.
