When supplying power wirelessly to an onboard power reception device, a beam emission unit in a beam reception and emission unit (120) emits a laser beam progressing along the upper surface of a power transmission unit (170) to scan the upper part of the entire upper surface of the power transmission unit (170). When receiving a reflected beam, the beam reception unit in the beam reception and emission unit (120) sends the results of beam reception to a determination unit. The determination unit determines the presence or absence of a foreign substance supported on at least one projection existing on the upper surface of the contactless charging unit (110) on the basis of the results of beam reception. Subsequently, when a foreign substance is present on the upper surface of the contactless charging unit (110), the control unit generates a supply control command indicating that no power is to be supplied to the onboard power reception device and sends the command to a supply unit. This will enable wireless power supply using the contactless system without any problem in terms of safety."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Contactless charging device and method for controlling power supply","description":"A plurality of projections is arranged in a matrix on the upper surface of the housing of a contactless charging unit (110).
