Abstract
There is provided a wireless charging apparatus. The wireless charging apparatus comprises: a power transmitter for wirelessly transmitting power to a battery; a temperature sensor for detecting at least one of a temperature of the power transmitter, a temperature of the battery, and a temperature of a power receiver; and a controller for changing a current profile of the power transmitter based on the temperature.
Claims18
A wireless charging apparatus comprising:
- a power transmitter configured to wirelessly transmit power to a battery;
- a temperature sensor configured to detect at least one of a temperature of the power transmitter, a temperature of the battery, and a temperature of a power receiver;
- and
- a controller configured to change a current profile of the power transmitter based on the temperature,
- wherein when the temperature is less than a preset reference temperature, the controller controls power transmission of the power transmitter based on a preset first current profile, and
- when the temperature is equal to or greater than the preset reference temperature, the controller controls power transmission of the power transmitter based on a second current profile in which a lower current flows than that in the first current profile.
A control method of a wireless charging apparatus, comprising:
- transmitting power wirelessly to the battery;
- sensing a temperature;
- and
- changing a current profile of a power transmitter for transmitting the power based on the temperature,
- wherein the changing of the current profile based on the temperature comprises controlling power transmission of the power transmitter based on a preset first current profile when the temperature is less than a preset reference temperature, and controlling the power transmission of the power transmitter based on a second current profile in which a lower current flows than that in the first current profile when the temperature is equal to or greater than the preset reference temperature.
A non-transitory computer-readable recording medium storing a computer program, comprising commands for a processor to perform a method, the method comprising:
- transmitting power wirelessly to the battery;
- sensing a temperature;
- and
- changing a current profile of a power transmitter for transmitting the power based on the temperature,
- wherein the changing of the current profile based on the temperature comprises controlling power transmission of the power transmitter based on a preset first current profile when the temperature is less than a preset reference temperature, and controlling the power transmission of the power transmitter based on a second current profile in which a lower current flows than that in the first current profile when the temperature is equal to or greater than the preset reference temperature.
