Application: Feed unit, feed system, and electronic device for increasing power supplied to a battery based on a device state and/or a control of a charging current (Patent ID: US20240063446A1)
The patent filed by Sony Group Corp. describes a feed unit that includes a power transmission section using a magnetic or electric field to transmit power to a device with a secondary battery. The power transmission control section regulates the power transmission operation, particularly during a charging period when the secondary battery is being charged based on the transmitted power. When the device with the secondary battery is activated, the power-transmission control section adjusts the power transmission operation to increase the transmitted power.
The claims of the patent detail an electronic device with a power receiving coil to receive wireless power from a feed device, a voltage converting circuit to generate a specific voltage based on the transmitted power, a battery to store the power, and a control circuit to communicate with the feed device. The control circuit is designed to send a request to the feed device to decrease the transmitted power if it exceeds a minimum value and increase the transmitted power if it falls below the minimum value. This system allows for efficient power transmission and charging of electronic devices with secondary batteries.
