Electronic apparatus and method
An electronic apparatus includes a power receiving means for wirelessly receiving power, a detection means for detecting whether the electronic apparatus is in a predetermined state, a load means supplied with power from the power receiving means, and a control means that performs control so a second power is supplied from the power receiving means to the load means if the detection means detects that the electronic apparatus is in the predetermined state and a first power is supplied from the power receiving means to the load means, wherein the second power is lower than the first power, and the control means further performs control so the first power is supplied from the power receiving means to the load means if the detection means detects the electronic apparatus is in a state different from the predetermined state and the supplied power is reduced to a predetermined power value or less.
1. An electronic apparatus comprising:
a power receiving means configured to wirelessly receive power from a power supply apparatus;
a communication means configured to communicate with the power supply apparatus;
a temperature detection means configured to detect a temperature;
a detection means configured to detect whether the electronic apparatus is in a first state or a second state based on the temperature detected by the temperature detection means,
wherein the first state is a state in which the temperature is equal to or higher than a first temperature and lower than a second temperature, and
wherein the second state is a state in which the temperature is equal to or higher than the second temperature; and
a load means configured to be supplied with power received by the power receiving means,
characterized in that the electronic apparatus further includes a control means configured to:
(i) if the detection means detects that the electronic apparatus is in the first state, request the power supply apparatus to restrict a power output; and
(ii) if the detection means detects that the electronic apparatus is in the second state, restrict the power receiving means to supply power to the load means.
2. The electronic apparatus according to claim 1 , further comprising:
a voltage detection means configured to detect a voltage of a battery connected to the electronic apparatus,
wherein the control means restricts the power supply from the power receiving means to the load means in a case where the voltage.
3. The electronic apparatus according to claim 1 , further comprising:
a current detection means configured to detect a current flowing to a battery connected to the electronic apparatus,
wherein the control means restricts the power supply from the power receiving means to the load means in a case where the current flowing to the battery is equal to or lower than a predetermined current.
4. The electronic apparatus according to claim 1 , wherein
the control means restricts the power supply from the power receiving means to the load means in a case where an error relating to charging of a battery connected to the electronic apparatus is occurring in the electronic apparatus.
5. The electronic apparatus according to claim 1 , wherein
the control means restricts the power supply from the power receiving means to the load means in a case where an error relating to wireless power supplying from the power supply apparatus to the electronic apparatus is occurring.
6. The electronic apparatus according to claim 1 , wherein,
in a case where the detection means detects that the electronic apparatus is in the first state in a state where power supplied from the power receiving means to the load means is restricted, the control means cancels the restriction of the power supply from the power receiving means to the load means.
7. A power supply apparatus comprising:
a power supply means configured to wirelessly transmit power to an electronic apparatus according to claim 1 ; and
a processing means configured to control the power supply apparatus.
8. A method for controlling an electronic apparatus having the power receiving means and the load means, the method comprising:
wirelessly receiving power from a power supply apparatus;
detecting a temperature;
detecting whether the electronic apparatus is in a first state or a second state based on the temperature detected by the detecting,
wherein the first state is a state in which the temperature is equal to or higher than a first temperature and lower than a second temperature, and
wherein the second state is a state in which the temperature is equal to or higher than the second temperature;
performing control to, if the electronic apparatus is in the first state, request the power supply apparatus to restrict a power output; and
performing control to, if the electronic apparatus is in the second state, restrict the power supply from the power receiving means to the load means.
9. The method according to claim 8 , further comprising:
detecting a voltage of a battery connected to the electronic apparatus, and
restricting the power supply from the power receiving means to the load means in a case where the voltage of the battery is equal to or higher than a predetermined voltage.
10. The method according to claim 8 , further comprising:
detecting a current flowing to a battery connected to the electronic apparatus, and
restricting the power supply from the power receiving means to the load means in a case where the current flowing to the battery is equal to or lower than a predetermined current.
11. The method according to claim 8 , further comprising:
cancelling, in a case where it is detected that the electronic apparatus is in the first state in a state where power supplied from the power receiving means to the load means is restricted, the restriction of the power supply from the power receiving means to the load means.
12. A non-transitory storage medium storing a program for causing a computer to execute a method for controlling an electronic apparatus according to the method of claim 8 .
