## Abstract

A device including a power transmitting coil for providing electric power; a thermal sensor; and a circuit operative to: before start of transmitting first electric power for charging, cause the power transmitting coil to supply second electric power to a charging space; cause the thermal sensor to detect whether temperature in the charging space increases after the second electric power is transmitted; before start of transmitting the first electric power, determine chargeability based on presence information and foreign object information, the presence information indicating whether a mobile object is present in the charging space, and the foreign object information indicating whether the temperature in the charging space increases, and cause the power transmitting coil to transmit the first electric power in a case the circuit determines chargeable. The second electric power is lower than the first electric power, and the second electric power is supplied before the mobile object is located on the charging space.

## Claims

### Claim 1

A device comprising:
a power transmitting coil for providing electric power;
a thermal sensor; and
a circuit operative to:
before start of transmitting first electric power for charging, cause the power transmitting coil to supply second electric power to a charging space;
cause the thermal sensor to detect whether temperature in the charging space increases after the second electric power is transmitted;
before start of transmitting the first electric power, determines chargeability based on presence information and foreign object information, the presence information indicating whether a mobile object is present in the charging space, and the foreign object information indicating whether the temperature in the charging space increases, and
cause the power transmitting coil to transmit the first electric power in a case the circuit determines chargeable, wherein
the second electric power is lower than the first electric power, and
the second electric power is supplied before the mobile object is located on the charging space.
