  • Patent number: 11489212
    Abstract: A method of controlling a plurality of batteries and an electronic device to which the same is applied. The electronic device includes a housing and a plurality of batteries. The electronic device also includes a power management module, a plurality of current limiting ICs, and a processor operationally connected to the plurality of batteries, the power management module and the plurality of current limiting ICs. The processor is configured to sense a sum of the currents flowing into the plurality of batteries or a voltage of the power management module, perform a primary end of reducing a magnitude of the sum of the currents flowing into the plurality of batteries, sense the currents or voltages of the plurality of batteries, and perform a secondary end of blocking a current flowing into a battery.

  • Patent number: 11218016
    Abstract: An electronic device and method are provided for frequency interference cancellation. The electronic device includes a coil, a wireless power receive circuit, a charging circuit, a display, and a processor. The processor may be configured to perform wireless charging with power wirelessly received from a wireless charger, change, via the charging circuit, a charging current of the electronic device from an initial current level to a first current level, based on the display being switched on during wireless charging, change, via the wireless power receive circuit, a charging voltage of the electronic device from an initial voltage level to a first voltage level, transmit, via the coil, a packet for changing a charging voltage of the wireless charger, change, via the wireless power receive circuit, the charging voltage of the electronic device to a second voltage level upon transmission of the packet, and change the charging current to the initial current level.
