Abstract
A plurality of electronic devices including batteries and being connected to each other may respectively include battery managing apparatuses that may enable the electronic devices to share power of the batteries included in the electronic devices, more particularly, battery managing apparatuses that may change a mode or a manner to connect the batteries to the electronic devices by comparing states of charge (SoCs) of the batteries.
Claims20
A method of managing batteries included in electronic devices, comprising:
- obtaining information related to the batteries;
- comparing residual capacities of the batteries based on the information;
- and
- determining a power reception mode for the electronic devices based on the residual capacities, the power reception mode being a scheme for the electronic devices to receive power from different ones of the batteries.
A battery managing apparatus included in an electronic device, the battery managing apparatus comprising:
- a switch connected to a local battery included in the electronic device;
- and
- a power controller configured to,
- obtain information related to the local battery included in the electronic device and one or more external batteries included in one or more other electronic devices,
- compare residual capacities of the local battery included in the electronic device and the one or more external batteries included in the one or more other electronic devices based on the information, and
- determine a power reception mode based on the residual capacities, the power reception mode being a scheme in which the electronic device receives power from one of the local battery and the one or more external batteries.
A battery managing method, comprising:
- measuring residual capacities of batteries respectively included in electronic devices;
- analyzing differences between the residual capacities of the batteries;
- and
- determining a power reception mode based on the residual capacities, the power reception mode being a scheme for the electronic devices to receive power from different ones of the batteries.
