NON-CONTACT POWER TRANSMISSION DEVICE |
摘要 |
A contactless power transmission device (power transmission device 90) includes: a plurality of power transmission coil units (700-1 to 700-5); a plurality of detection units (701-1 to 701-5) configured to detect a foreign substance on and around each power transmission coil unit; a communication unit (810) configured to communicate with a vehicle (10); and a control unit (800) configured to select one of the plurality of power transmission coil units (700-1 to 700-5) based on information about a mounting position of a power reception device (power reception coil unit 100) from the vehicle (10) obtained by the communication unit (810), and to guide, when a detection unit detects a foreign substance at the selected power transmission coil unit, the vehicle toward a power transmission coil unit different from the selected power transmission coil unit, before the vehicle (10) stops. This can prevent a reduction in power transfer efficiency due to a foreign substance or the like in a power transmission device (contactless power transmission device) including a plurality of power transmission coils. |
