Abstract

A power supply apparatus includes a receiving unit configured to receive a power supply request and a power supply condition from a power receiving apparatus, and a power supply control unit configured to instruct a power supply unit to perform a test power supply to a target power receiving apparatus which is a transmission source of the power supply request, and instruct the power supply unit to perform actual power supply according to the power supply condition when the receiving unit receives a success notification of the test power supply from the target power receiving apparatus after performing the test power supply.

Claims

1. A power supply apparatus comprising:

a receiving unit configured to receive a power supply request and a power supply condition from a power receiving apparatus; and

a power supply control unit configured to instruct a power supply unit to perform a test power supply to a target power receiving apparatus that is a transmission source of the power supply request, and to instruct the power supply unit to perform actual power supply according to the power supply condition when the receiving unit receives a success notification of the test power supply from the target power receiving apparatus after performing the test power supply.

2. The power supply apparatus according to claim 1, further comprising a power supply condition management unit configured to store the power supply condition in a storage unit by associating the power supply condition with the target power receiving apparatus when the receiving unit receives the success notification from the target power receiving apparatus,

wherein, when the receiving unit receives the power supply request, and the power supply condition of the target power receiving apparatus is stored in the storage unit, the power supply control unit instructs the power supply unit to perform the actual power supply to the target power receiving apparatus without performing the test power supply.

3. The power supply apparatus according to claim 2, wherein, when the receiving unit receives the power supply request from the target power receiving apparatus, and the power supply condition of the target power receiving apparatus is not stored in the storage unit, the power supply control unit instructs the power supply unit to perform the test power supply to the target power receiving apparatus.

4. A power supply method executed by a power supply apparatus, the power supply method comprising:

receiving a power supply request from a power receiving apparatus;

receiving a power supply condition from the power receiving apparatus;

controlling a power supply by instructing a power supply unit to perform a test power supply to a target power receiving apparatus that is a transmission source of the power supply request; and

controlling a power supply by instructing the power supply unit to perform actual power supply according to the power supply condition when a success notification of the test power supply is received from the target power receiving apparatus after performing the test power supply.

5. A computer-readable storage medium storing computer executable instructions for causing a computer to execute a method, the method comprising:

receiving a power supply request from a power receiving apparatus;

receiving a power supply condition from the power receiving apparatus;

controlling a power supply by instructing a power supply unit to perform a test power supply to a target power receiving apparatus that is a transmission source of the power supply request; and

controlling a power supply by instructing the power supply unit to perform actual power supply according to the power supply condition when a success notification of the test power supply is received from the target power receiving apparatus after performing the test power supply.
