Title:
CHARGING DEVICE
Document Type and Number:
Japanese Patent JP2023043979
Kind Code:
A
Abstract:
To provide a charging device capable of more reliably suppressing communication medium held by a power reception device from being broken at charging.SOLUTION: A charging device 10 comprises: a charging coil 11; a charging controller 13; an antenna 14; a communication controller 16; and a controller 18 that controls the charging controller 13 and the communication controller 16. The controller 18 executes: first communication medium detection processing of detecting communication medium by wireless communication via the antenna 14; second communication medium detection processing of detecting the communication medium by wireless communication via the antenna 14 after the communication medium is detected in the first communication medium detection processing; and power reception device detection processing of detecting presence or absence of a power reception device within a range that the charging coil 11 can be charged when no communication medium is detected in the second communication medium detection processing. When the power reception device is detected in the power reception device detection processing, the charging controller 13 is controlled so as not to supply power to the power reception device.SELECTED DRAWING: Figure 2
