1. A power transmission device comprising:
- a power transmitter that wirelessly transmits power to a power receiving device;
a memory that stores instructions;
a processor that executes the instructions to;
acquire a receiving power amount from a specific power receiving device to which the power transmitter is transmitting power;
determine whether the acquired receiving power amount is smaller than a reference value calculated based on a maximum value of receiving power amounts previously acquired from the specific power receiving device; and
prompt, in a case where it is determined that the acquired receiving power amount is smaller than the reference value, a user to bring the specific power receiving device closer to the power transmission device.

Abstract
A power transmission device that wirelessly supplies power with a power receiving device includes a power transmission unit configured to wirelessly transmit power to a power receiving device, a receiving unit configured to receive a receiving power amount from the power receiving device, an evaluation unit configured to compare a reference value of the power receiving device and the receiving power amount and evaluate a transmission efficiency of power to the power receiving device based on a comparison result, and a transmission unit configured to transmit an evaluation result by the evaluation unit to the power receiving device.

5. A power transmission method executed by a power transmission device, the method comprising:
-
wirelessly transmitting power to a power receiving device; acquiring a receiving power amount from a specific power receiving device to which the power transmitter is transmitting power; determining whether the acquired receiving power amount is smaller than a reference value calculated based on a maximum value of receiving power amounts previously acquired from the specific power receiving device; and prompting, in a case where it is determined that the acquired receiving power amount is smaller than the reference value, a user to bring the specific power receiving device closer to the power transmission device.

6. A non-transitory computer-readable storage medium storing computer executable instructions that cause a computer to execute a power transmission method, the method comprising:
-
wirelessly transmitting power to a power receiving device; acquiring a receiving power amount from a specific power receiving device to which the power transmitter is transmitting power; determining whether the acquired receiving power amount is smaller than a reference value calculated based on a maximum value of receiving power amounts previously acquired from the specific power receiving device; and prompting, in a case where it is determined that the acquired receiving power amount is smaller than the reference value, a user to bring the specific power receiving device closer to the power transmission device.
