POWER RECEPTION DEVICE AND CHARGING CONTROL PROGRAM
First Claim
1. A power reception device comprising:
- a power reception coil that receives power from a power supply device in a non-contact manner;
a power reception unit configured to cause the received power as a charging current to flow to a load;
a control unit configured to start charging by the charging current which is set to a first current value, to control the charging current so as to increase the charging current, and to notify a notification unit that a relative position of the power reception device to the power supply device is inappropriate if the charging stops before the charging current reaches a second current value larger than the first current value.

Abstract
According to one embodiment, there is provided a power reception device including: a power reception coil, a power reception unit, a notification unit, and a control unit. The power reception coil receives power from a power supply device in a non-contact manner. The power reception unit causes the received power as a charging current to flow to a load. The notification unit notifies that a relative position of the power reception device to the power supply device is inappropriate. The control unit starts charging by the charging current which is set to a first current value and controls the charging current so as to gradually increase the charging current. If the charging is stopped before the charging current reaches a second current value larger than the first current value, notification is performed that the relative position of the power reception device to the power supply device is inappropriate.
