WIRELESS CHARGING DEVICE AND METHOD FOR CONTROLLING WIRELESS CHARGING
摘要
A wireless charging device (40) arranged in a vehicle including an in-vehicle device (20). The in-vehicle device transmits a wake signal in intervals until receiving a response from an electronic key (10) and communicates with the electronic key when receiving the response to determine whether the electronic key is authentic. The wireless charging device includes a primary coil (L1) that transmits power to a charged device (50) when supplied with alternating current. A detection unit (43) uses the wake signal to detect when communication starts between the in-vehicle device and the electronic key. A power supplying suppression unit (43) reduces the alternating current supplied to the primary coil over a certain time from when the communication starts. The power supplying suppression time includes the time required for a series of communication to be performed between the in-vehicle device and the electronic key for the verification.
