[0033] For example, the electronic device (100) may include a smart phone having a bar type shape. The electronic device (100) may include a first battery (101-1) and a second battery (101-2). According to one embodiment, the first battery (101-1) and the second battery (101-2) may include, for example, a rechargeable secondary battery or a fuel cell. The first battery (101-1) and the second battery (101-2) may be discharged as they provide power to the hardware of the electronic device (100). As the first battery (101-1) and the second battery (101-2) are discharged, a method of charging the first battery (101-1) and the second battery (101-2) may be required.
[0034] In order to charge the first battery (101-1) and the second battery (101-2), various types of charging devices (e.g., charging device (109) and / or wireless charging device (111)) may be provided. The charging device (109) may be connected to a port of the electronic device (100). The charging device (109) may transmit electric energy using the port. The electronic device (100) may use a component (e.g., PMIC) within the electronic device (100) to charge the first battery (101-1) and the second battery (101-2) using the transmitted electric energy. The wireless charging device (111) may charge the first battery (101-1) and the second battery (101-2) based on contact with (or separation from) the electronic device (100). For example, the battery capacity (e.g., total capacity) of the first battery (101-1) and the battery capacity of the second battery (101-2) may have different capacities. The battery capacity may refer to the total amount of charge that can be stored in the battery. The battery capacity may be measured in ampere hours (Ah) or may be parameterized.
[0035] In one embodiment, the electronic device (100) may have a form factor (e.g., size or physical properties) of a rollable smartphone (100-1) and / or a foldable smartphone (100-2). For example, the rollable smartphone (100-1) may include a housing including a first housing part and a second housing part configured to be movably coupled with the first housing part between a collapsed position and an expanded position. The housing part may be referred to as a part that forms the exterior of the rollable smartphone (100-1).
[0036] The rollable smartphone (100-1) may include a flexible display coupled to the first housing part and the second housing part such that the size of an area of the flexible display visible on the front side of the housing changes as the housing moves between the collapsed position and the expanded position. For example, the rollable smartphone (100-1) may include an actuator configured to move the second housing part relative to the first housing part.
[0037] For example, the first battery (101-1) may be included in the first housing part. The second battery (101-2) may be included in the second housing part. The first housing part and the second housing part may have different internal spaces. For example, based on the fact that the first housing part has a larger space than the second housing part, the first battery (101-1) having a larger capacity than the second battery (101-2) or the first battery (101-1) having a larger size than the second battery (101-2) may be placed in the first housing part. For example, based on the fact that the second housing part has a smaller space than the first housing part, the second battery (101-2) having a smaller capacity than the first battery (101-1) or the second battery (101-2) having a smaller size than the first battery (101-1) may be placed in the second housing part.
[0038] In one embodiment, the foldable smartphone (100-2) may be a foldable or bendable electronic device (100), as an example of the electronic device (100) illustrated in FIG. 1. The foldable smartphone (100-2) may include a foldable housing and a flexible or foldable display disposed within a space formed by the foldable housing. The foldable housing may include a first housing structure, a second housing structure, and a hinge structure.
[0039] The first housing structure and the second housing structures may have different internal spaces. For example, based on the fact that the first housing structure has a larger space than the second housing structure, a first battery (101-1) having a larger capacity than the second battery (101-2) or a first battery (101-1) having a larger size than the second battery (101-2) may be placed in the first housing structure. For example, based on the fact that the second housing structure has a smaller space than the first housing structure, a second battery (101-2) having a smaller capacity than the first battery (101-1) or a second battery (101-2) having a smaller size than the first battery (101-1) may be placed in the second housing structure.
[0040] The electronic device (100) can perform various functions (e.g., a call function, a photographing function, or a display display function) using the power of the first battery (101-1) and the power of the second battery (101-2). The electronic device (100) can include various electronic components to perform the various functions.
[0041] The mode of the electronic device (100) may include a power on mode (103), a power off mode (105), and a shipping mode (107). The mode of the electronic device (100) may be referred to as a state of the electronic device (100). The state of the electronic device (100) may include a power-on state, a power-off state, and a shipping state. The power on mode (103) and the power on state may be the same. The power off mode (105) and the power off state may be the same. The shipping mode (107) and the shipping state may be the same. The mode of the electronic device (100) may be divided into a plurality of modes (e.g., power on mode (103), power off mode (105), or shipping mode (107)) depending on the state of the first battery (101-1) (e.g., voltage of the first battery (101-1), current of the first battery (101-1), charge amount of the first battery (101-1), capacity of the first battery (101-1)) and the state of the second battery (101-2) (e.g., voltage of the second battery (101-2), current of the second battery (101-2), charge amount of the second battery (101-2), capacity of the second battery (101-2)). The charge amount may be referred to as the amount of charge possessed by a charging body (e.g., first battery (101-1)). Battery capacity may be referred to as the amount of charge that a battery can store and transmit. The mode of the electronic device (100) may be switched from at least one of the plurality of modes to another mode of the electronic device (100) depending on the state of the first battery (101-1) and the state of the second battery (101-2).
[0042] In the power-on mode (103), the various functions can be executed by the electronic device (100). For example, in the power-on mode (103), the electronic device (100) can display the battery state (SOC) of the electronic device (100) on the display of the electronic device (100). The battery state can be referred to as the amount of electricity that can be used by the battery. The battery state can be determined using a chemical measurement method, a voltage measurement method, an amperometric method, an open circuit voltage (OCV) measurement method, and / or a pressure measurement method.
[0043] For example, if the electronic device (100) is compatible with the advanced configuration and power interface (ACPI) standard, in one embodiment, the power-on mode (103) of the electronic device (100) may be an S0 state or an S1 state. For example, in the S0 state, all hardware of the electronic device (100) may be in a working state. For example, in the S1 state, the input / output devices (e.g., a display) and the processor of the electronic device (100) may be in a state where no power is supplied.
[0044] For example, the power on mode (103) may refer to a power management mode in which power from the first battery (101-1) and power from the second battery (101-2) are provided to one or more load electrical components based on the voltage of the first battery (101-1) and the voltage of the second battery (101-2) being higher than a reference voltage. The reference voltage may be, for example, 3.4 V. In the present disclosure, the reference voltage may be referred to as a lower limit threshold of the power on mode (103), a lower limit voltage of the power on mode (103), and / or a first reference voltage. The first reference voltage may represent a reference voltage used to change the state of the electronic device (100) to a power off state (105) without a user input for changing the state of the electronic device (100) to a power off state. For example, the power on mode (103) may refer to a power management mode that provides power of the first battery (101-1) and power of the second battery (101-2) to one or more load electrical components based on the voltage of the first battery (101-1) and the voltage of the second battery (101-2) being about 3.4 V or higher. Based on executing the various functions in the power on mode (103), the first battery (101-1) and the second battery (101-2) may be discharged.
[0045] Based on the discharge of the first battery (101-1) and the second battery (101-2), the voltage of the first battery (101-1) and the voltage of the second battery (101-2) may be lowered below a first reference voltage (e.g., about 3.4 V). Based on the voltage of the first battery (101-1) and the second battery (101-2) being lowered below the first reference voltage, the mode of the electronic device (100) may be switched from the power on mode (103) to the power off mode (105). For example, the electronic device (100) may be switched from the power on mode (103) to the power off mode (105) based on identifying (or determining) that the voltage of the first battery (101-1) and the voltage of the second battery (101-2) are lowered below the first reference voltage.
[0046] The electronic device (100) may stop displaying screens other than a screen for notifying that charging is required on the display of the electronic device (100) based on switching to the power off mode (105).
[0047] For example, the power off mode (105) may refer to a power management mode that stops providing the power of the first battery (101-1) and the power of the second battery (101-2) to at least some load circuits of the one or more load electrical components based on the voltage of the first battery (101-1) and the voltage of the second battery (101-2) being between the first reference voltage and the second reference voltage (e.g., about 2.8 V). The power off state of the electronic device (100) may indicate a state of the electronic device (100) that stops providing electrical power to one or more load electrical components. In the present disclosure, the second reference voltage may be referred to as a lower limit threshold of the power off mode (105), a lower limit voltage of the power off mode (105), and / or a second reference voltage. The electronic device (100) in power-on mode (103) may switch from power-on mode (103) to power-off mode (105) when the voltages of both the first battery (101-1) and the second battery (101-2) decrease below the first reference voltage. For example, at least some load circuits among the one or more load electrical components may be deactivated based on the voltage of the first battery (101-1) and the voltage of the second battery (101-2) being between the first reference voltage and the second reference voltage. The power-off mode (105) may refer to a mode of the electronic device (100) that stops providing power to the at least some load circuits that are deactivated.
[0048] For example, if the electronic device (100) is ACPI compliant, in one embodiment, in the power off mode (105), the power saving state may be an S3 (sleep mode) state, an S4 (standby mode) state, or an S5 (soft off) state. For example, when the electronic device (100) is in the S3 state, power may be supplied to the memory of the electronic device (100), and power may not be supplied to the processor of the electronic device (100). For example, when the electronic device (100) is in the S4 state, power may not be supplied to the memory and the processor. For example, in the S5 state, the electronic device (100) may be completely shut down without a power saving mode file in the system of the electronic device (100). If the electronic device (100) is shut down without the above power saving mode file, the period for rebooting may be relatively longer than in other power saving modes (e.g., S1 state).
[0049] Meanwhile, the materials inside the first battery (101-1) and the second battery (101-2) may be oxidized (or deteriorated). Based on the oxidation (or deterioration) of the first battery (101-1) and the second battery (101-2), permanent damage may occur to the first battery (101-1) and the second battery (101-2), such as swelling.
[0050] The silicon anode material, which is a component of a battery, can experience approximately 300% volume expansion during the battery's charging and discharging processes. As the silicon anode material repeatedly expands and contracts, the solid electrolyte interphase (SEI) layer, a film formed on the surface of the anode material, can be broken. As the silicon anode material repeatedly expands and contracts, a new anode surface can appear. As the silicon anode material repeatedly expands and contracts, a SEI layer can form again on the newly formed surface. As the battery is repeatedly charged and discharged, a new SEI layer continuously forms, and the electrolyte can be depleted. Based on the formation of the SEI layer and the depletion of the electrolyte, the battery's lifespan can be reduced. As gases are generated during the repeated charging and discharging of the battery, a phenomenon called battery swelling can occur. Gases accumulating inside the battery can cause the battery to explode, burn out, and / or catch fire. Accordingly, a method for preventing or delaying the swelling phenomenon may be required.
[0051] The swelling phenomenon can be accelerated based on the battery voltage being very low. The electronic device (100) can delay the point in time when the voltage of the battery with a smaller capacity among the first battery (101-1) or the second battery (101-2) drops below the voltage at which the swelling phenomenon is accelerated based on controlling the charging between the first battery (101-1) and the second battery (101-2) having different capacities.
[0052] In order to delay (or prevent) (or slow down) the swelling phenomenon, the mode of the electronic device (100) may include the shipping mode (107). The mode of the electronic device (100) may be switched from the power off mode (105) to the shipping mode (107) based on the voltage of the first battery (101-1) and the voltage of the second battery (101-2) becoming lower than a second reference voltage.
[0053] For example, the delivery mode (107) may include a mode that stops providing power from the first battery (101-1) and power from the second battery (101-2) to the one or more load electrical components based on the voltage from the first battery (101-1) and the voltage from the second battery (101-2) being less than a second reference voltage (e.g., about 2.8 V).
[0054] For example, the delivery mode (107) may include a mode for disconnecting electrical connections between the one or more load electrical components from the first battery (101-1) and the second battery (101-2) to stop providing the power from the first battery (101-1) and the power from the second battery (101-2) to the one or more load electrical components.
[0055] Within the above shipping mode (107), the electronic device (100) may include the circuit of FIG. 2 for balancing the remaining amount of the first battery (101-1) and the remaining amount of the second battery (101-2).
[0056] For example, if the electronic device (100) is compatible with the ACPI standard, in one embodiment, within the shipping mode (107), the power saving state may be the S6 state. For example, if the electronic device (100) is in the S6 state, the first battery (101-1) and the second battery (101-2) of the electronic device (100) may be electrically disconnected from hardware other than the first battery (101-1) and the second battery (101-2) of the electronic device (100).

[0059] The PMIC (201) may include a first switch (202). The first switch (202) may include a first terminal (202-1) electrically connected to the switching circuit (203) and a second terminal (202-2) electrically connected to the second battery (101-2). For example, the first switch (202) may be referred to as a Qbat switch.
[0060] The switching circuit (203) may include a second switch (204). The second switch (204) may include a third terminal (204-1) electrically connected to the PMIC (201) and a fourth terminal (204-2) electrically connected to the first battery (101-1). The switching circuit (203) may include a limiter circuit that limits overcharging and / or overdischarging of the first battery (101-1). The switching circuit (203) may be configured to establish or disconnect an electrical connection between the first battery (101-1) and another circuit, which is established in the switching circuit (203), by using a voltage and / or current applied to the first battery (101-1).
[0061] The electronic device (100) may include an individual charging structure for performing individual charging through an electrical connection between components of the electronic device (100) (e.g., a PMIC (201) or a switching circuit (203)). The individual charging structure may be referred to as a structure that distributes heat generated by charging the first battery (101-1) and the second battery (101-2) based on receiving power from an external power source (e.g., a charging device (109) or a wireless charging device (111)), using the PMIC (201), and charging the first battery (101-1) using the boosting circuit (205).
[0062] The electronic device (100) may include an interface for receiving power from the external power source (e.g., a charging device (109) or a wireless charging device (111)). For example, the interface may include a port (217) (e.g., a USB Type C port) for receiving electrical energy from a power distribution system such as an outlet. For example, the port (217) may have a structure based on a universal serial bus (USB) Type C receptacle. Based on the structure of the USB Type C receptacle, the port (217) may include Dp1, Dn1, and / or CC pins. The interface may further include a mux integrated circuit (MUIC) for data communication based on the Dp1 and the Dn1.
[0063] For example, the port (217) may have a structure based on a universal serial bus (USB) type A receptacle. Based on the structure of the USB type A receptacle, the port (217) may include D+ and D- pins.
[0064] For example, the interface may include an antenna or wireless charging circuit for wirelessly receiving electrical energy based on electric and / or magnetic fields.
[0065] The one or more load electrical components (207) may include hardware for processing data based on one or more instructions. The hardware for processing the data may include, for example, an arithmetic and logic unit (ALU), a floating point unit (FPU), a field programmable gate array (FPGA), a central processing unit (CPU), a graphic processing unit (GPU), a neural processing unit (NPU), and / or an application processor (AP). The number of hardware for processing the data may be one or more. The hardware for processing the data may include an application processor. For example, the application processor may have a multi-core processor structure such as a dual core, a quad core, or a hexa core.
[0066] The at least one power management circuit (200) may be electrically connected to the first battery (101-1), the second battery (101-2), the at least one load electrical component (207), and the port (217).
[0067] The PMIC (201) may be electrically connected to the second battery (101-2). The PMIC (201) may be electrically connected to the port (217). The PMIC (201) may be electrically connected to the boosting circuit (205). The PMIC (201) may be electrically connected to one or more load electrical components (207). The PMIC (201) may be connected to the boosting circuit (205) through a signal path (209).
[0068] For example, the signal path (209) connecting the PMIC (201) and the boosting circuit (205) may be configured to transmit and / or receive electrical signals based on a system power management interface (SPMI), an inter-integrated circuit (I2C) communication, a serial peripheral interface (SPI), and / or a mobile industry processor interface (MIPI). The embodiment is not limited thereto, and the signal path (209) may include any conductive line for transmitting a control signal having a voltage (e.g., designated voltages set to represent a specific bit, referred to as high or low).
[0069] The switching circuit (203) may be electrically connected to the PMIC (201). The switching circuit (203) may be electrically connected to the first battery (101-1). The switching circuit (203) may be electrically connected to the boosting circuit (205). The switching circuit (203) may be electrically connected to one or more load electrical components (207).
[0070] As described above, the modes of the electronic device (100) may include a power-on mode (103), a power-off mode (105), and / or a shipping mode (107). Hereinafter, the operation of the electronic device (100) (or the circuit of FIG. 2) in the power-on mode (103) is described.
[0071] Within the power-on mode (103), the PMIC (201) can provide power of the second battery (101-2) to one or more load electrical components (207). The switching circuit (203) can provide power of the first battery (101-1) electrically connected to the switching circuit (203) to one or more load electrical components (207). For example, the one or more load electrical components (207) can include an application processor. The application processor can identify (or determine) (or calculate) the remaining power of the first battery (101-1) and the remaining power of the second battery (101-2) within the power-on mode (103).
[0072] As the power of the first battery (101-1) and the power of the second battery (101-2) are provided to the one or more load electrical components (207), the voltage of the first battery (101-1) and the voltage of the second battery (101-2) may decrease. Based on the voltage of the first battery (101-1) and the voltage of the second battery (101-2) becoming lower than a first reference voltage, the mode of the electronic device (100) may be switched from the power on mode (103) to the power off mode (105).
[0073] The application processor may determine to switch from the power on mode (103) to the power off mode (105) based on the voltage of the first battery (101-1) and the voltage of the second battery (101-2) being lower than a first reference voltage. In one embodiment, the application processor may transmit a reference charge amount to the PMIC (201) to be used as a target charge capacity of the second battery (101-2) within the shipping mode (107) based on the determination to switch the mode of the electronic device (100) from the power on mode (103) to the power off mode (105).
[0074] The application processor may transmit the remaining capacity of the second battery (101-2) to the PMIC (201) to be used as the target charge capacity of the second battery (101-2) within the shipping mode (107) based on determining to switch the mode of the electronic device (100) from the power on mode (103) to the power off mode (105).
[0075] For example, the reference charge amount may be determined based on the point in time when the battery swelling phenomenon of the first battery (101-1) accelerates and the point in time when the battery swelling phenomenon of the second battery (101-2) accelerates. Accordingly, the reference charge amount may be set so that the point in time when the battery swelling phenomenon of the first battery (101-1) accelerates and the point in time when the battery swelling phenomenon of the second battery (101-2) accelerates are the same. The reference charge amount may be determined based on the difference between the point in time when the battery swelling phenomenon of the first battery (101-1) accelerates and the point in time when the battery swelling phenomenon of the first battery (101-1) accelerates. Accordingly, the reference charge amount may be set so that the difference is less than a certain period of time.
[0076] The above reference charge amount may be a charge amount calculated by considering the cycle of the first battery (101-1), the cycle of the second battery (101-2), and coulombic efficiency while the first battery (101-1) charges the second battery (101-2).
[0077] Below, the operation of the electronic device (100) (or the circuit of FIG. 2) in the power off mode (105) is described. The operations of the electronic device (100) are described.
[0078] Within the power off mode (105), the PMIC (201) may stop providing power of the second battery (101-2) electrically connected to the PMIC (201) to the one or more load electrical components (207) based on the mode of the electronic device (100) being switched from the power on mode (103) to the power off mode (105).
[0079] The switching circuit (203) can stop providing power of the first battery (101-1) electrically connected to the switching circuit (203) to the one or more load electrical components (207) based on the mode of the electronic device (100) being switched from the power-on mode (103) to the power-off mode (105).
[0080] Within the power off mode (105), the power of the first battery (101-1) and the power of the second battery (101-2) may be discharged. As the power of the first battery (101-1) and the power of the second battery (101-2) are discharged, the voltage of the first battery (101-1) and the voltage of the second battery (101-2) may decrease.
[0081] The electronic device (100) can compare the voltage of the first battery (101-1) and the voltage of the second battery (101-2) with a second reference voltage (e.g., 2.8 V). Based on the voltage of the first battery (101-1) and the voltage of the second battery (101-2) being lower than the second reference voltage, the mode of the electronic device (100) can be switched from the power off mode (105) to the shipping mode (107).
[0082] Below, the operations of the electronic device (100) within the shipping mode (107) are described.
[0083] The mode of the electronic device (100) may enter the shipping mode (107) based on the voltage of the second battery (101-2) electrically connected to the PMIC (201) being lower than a second reference voltage. In order to enter the shipping mode (107), the PMIC (201) may control the first switch (202) to electrically disconnect the first terminal (202-1) and the second terminal (202-2). The PMIC (201) may disconnect the electrical connection between the one or more load electrical components (207) based on the control of the first switch (202).
[0084] The mode of the electronic device (100) may enter the shipping mode (107) based on the voltage of the first battery (101-1) electrically connected to the switching circuit (203) becoming lower than the second reference voltage. The switching circuit (203) may control the second switch (204) to electrically disconnect the third terminal (204-1) and the fourth terminal (204-2). The switching circuit (203) may disconnect the electrical connection between the one or more load electrical components (207) based on the control of the second switch (204).
[0085] Based on determining that the mode of the electronic device (100) is switched from the power-off mode (105) to the shipping mode (107), the PMIC (201) can change a signal in the first state to a signal in the second state. The PMIC (201) can transmit the signal in the second state to the boosting circuit (205). The signal in the first state can represent a designated bit that instructs the boosting circuit (205) to deactivate the boosting circuit (205). The signal in the second state can include a designated bit that instructs the boosting circuit (205) to activate the boosting circuit (205) (e.g., boosting based on the boosting circuit (205).
[0086] The boosting circuit (205) may boost the voltage from the first battery (101-1) electrically connected to the boosting circuit (205) based on receiving a signal within the second state. The boosting circuit (205) may be configured to increase the voltage of the first battery (101-1) within a voltage range below a specified voltage that causes activation (e.g., turn-on) of one or more electrical components (207).
[0087] For example, the boosting circuit (205) can boost the voltage from the first battery (101-1) to a voltage that is twice the voltage from the first battery (101-1). For example, the boosting circuit (205) can boost the voltage from the first battery (101-1) to a voltage that is the voltage from the first battery (101-1) plus a headroom voltage (or margin voltage or padding voltage).
[0088] The boosting circuit (205) can provide power to the PMIC (201) electrically connected to the boosting circuit (205) using the boosted voltage from the first battery (101-1). The PMIC (201) can be configured to provide power received from the second node (213) to the second battery (101-2) using the boosted voltage obtained (or applied) from the boosting circuit (205).
[0089] Within the above shipping mode (107), the PMIC (201) can control the first switch (202) to electrically connect the first terminal (202-1) and the second terminal (202-2) only while providing power received from the second node (213) to the second battery (101-2). Charging of the second battery (101-2) can be performed based on the power provided from the PMIC (201).
[0090] Within the above shipping mode (107), charging the second battery (101-2) using the first battery (101-1) may be maintained or stopped based on at least one of the reference charge amount, reference remaining amount, and / or current of the second battery (101-2).
[0091] The PMIC (201) can identify the charge amount of the second battery (101-2) while the charging is being performed. Based on the charge amount of the second battery (101-2) being higher than the reference charge amount, the PMIC (201) can change the signal in the second state to the signal in the first state and transmit it to the boosting circuit (205).
[0092] For example, the PMIC (201) can identify the remaining amount of the second battery (101-2) while the charging is being performed. Based on the remaining amount of the second battery (101-2) becoming higher than the reference remaining amount, the PMIC (201) can change the signal in the second state into the signal in the first state and transmit it to the boosting circuit (205).
[0093] For example, as the second battery (101-2) is charged, the current flowing from the first battery (101-1) to the second battery (101-2) may decrease. For example, the PMIC (201) may identify the current of the second battery (101-2) while the charging is being performed. Based on the current of the second battery (101-2) becoming higher than the reference current, the PMIC (201) may change the signal in the second state into the signal in the first state and transmit it to the boosting circuit (205).
[0094] Based on the boosting circuit (205) receiving the signal within the first state, the boosting circuit (205) can stop boosting the voltage from the first battery (101-1). Based on the charge amount of the second battery (101-2) becoming higher than the reference charge amount, the PMIC (201) can control the first switch (202) to disconnect the electrical connection between the first terminal (202-1) and the second terminal (202-2).
[0095] For example, based on the remaining amount of the second battery (101-2) becoming higher than the reference remaining amount, the PMIC (201) can control the first switch (202) to disconnect the electrical connection between the first terminal (202-1) and the second terminal (202-2). For example, based on the current of the second battery (101-2) becoming higher than the reference current, the PMIC (201) can control the first switch (202) to disconnect the electrical connection between the first terminal (202-1) and the second terminal (202-2).
[0096] Based on the charge amount of the second battery (101-2) becoming higher than the reference charge amount, charging of the second battery (101-2) using the first battery (101-1) may be stopped. Based on the charging, the remaining amount of the first battery (101-1) and the remaining amount of the second battery (101-2) may be adjusted. Based on the adjustment of the remaining amount of the first battery (101-1) and the remaining amount of the second battery (101-2), the difference between the time point at which the swelling phenomenon of the first battery (101-1) accelerates based on the remaining amount of the first battery (101-1) and the time point at which the swelling phenomenon of the second battery (101-2) accelerates based on the remaining amount of the second battery (101-2) may be reduced. Accordingly, the time point at which the swelling phenomenon of the second battery (101-2) accelerates may be delayed.
[0097] Hereinafter, within the mode of the electronic device (100), a connection may be established with an external power source. According to the connection, charging of the electronic device (100) may proceed. The operation of the electronic device (100) according to the charging will be described.
[0098] Within the power on mode (103), based on the identification of the charging, the mode of the electronic device (100) may be maintained in the power on mode (103). Within the power off mode (105), based on the identification of the charging, the mode of the electronic device (100) may be switched to the power on mode (103). Within the shipping mode (107), based on the identification of the charging, the mode of the electronic device (100) may be switched to the power off mode (105) or the power on mode (103).
[0099] The above PMIC (201) can identify that a wired connection is established with the external power source based on the exchange of information performed using the port (217).
[0100] The PMIC (201) can identify that a wireless connection has been established with the external power source based on detecting a wireless charging device through the wireless charging circuit. The PMIC (201) can identify that a wireless connection has been established with the external power source by identifying the ping signal received through the wireless charging circuit.
[0101] For example, the PMIC (201) can identify (or detect) (or recognize) that an external power source is connected through information exchange of the CC pin of the port (217). Based on the identification, the PMIC (201) can control the first switch (202) to electrically connect the first terminal (202-1) and the second terminal (202-2). Based on the control of the first switch (202), the PMIC (201) can provide power of the second battery (101-2) electrically connected to the PMIC (201) to the one or more load electrical components (207).
[0102] Below, the operation of the PMIC (201) or the switching circuit (203) according to the charging within the above shipping mode (107) is described.
[0103] For example, the PMIC (201) can identify (or detect) (or recognize) that an external power source is connected through information exchange between the D+ and D- pins of the port (217). Based on the identification, the PMIC (201) can control the first switch (202) to electrically connect the first terminal (202-1) and the second terminal (202-1). Based on the control of the first switch (202), the PMIC (201) can provide power of the second battery (101-2) electrically connected to the PMIC (201) to the one or more load electrical components (207).
[0104] For example, the PMIC (201) can identify (or detect) (or recognize) that an external power source is connected through signal exchange of the wireless charging circuit. The PMIC (201) can electrically connect the first terminal (202-1) and the second terminal (202-1) by controlling the first switch (202). The PMIC (201) can provide power of the second battery (101-2) to the one or more load electrical components (207) based on the control of the first switch (202).
[0105] As the external power source is connected, the voltage provided from the third node (215) to the switching circuit (203) may become higher than the first reference voltage. Based on the voltage, the switching circuit (203) may control the second switch (204) to electrically connect the third terminal (204-1) and the fourth terminal (204-2). The switching circuit (203) may provide power of the first battery (101-1) electrically connected to the switching circuit (203) to the one or more load electrical components (207) based on the control of the second switch (204).
[0106] As an external power source is connected through the wireless charging circuit, the voltage provided from the third node (215) may increase above a first reference voltage. The switching circuit (203) may control the second switch (204) based on the voltage increased above the first reference voltage to electrically connect the third terminal (204-1) and the fourth terminal (204-2). The switching circuit (203) may provide power of the first battery (101-1) electrically connected to the switching circuit (203) to the one or more load electrical components (207) based on the control of the second switch (204).
[0107] Based on the power of the first battery (101-1) and the power of the second battery (101-2) being provided to the one or more load electrical components (207), the mode of the electronic device (100) can be switched from the shipping mode (107) to the power on mode (103) or the power off mode (105).
[0108] According to one embodiment, the PMIC (201) may charge the first battery (101-1) using the boosted voltage obtained (or applied) from the boosting circuit (205) while an external power source is connected. Similarly, the PMIC (201) may charge the second battery (101-2). The voltage of the first battery (101-1) may increase based on the charging. The electronic device (100) may be designed to stop the charging based on the increase in the voltage of the first battery (101-1). According to the stop, the charging of the second battery (101-2) may be stopped before the second battery (101-2) is charged to a reference charge amount. Accordingly, while the charging is in progress, a change in the reference voltage for the stop may be required. Hereinafter, an operation of changing the reference voltage of the PMIC (201) will be described.
[0109] The PMIC (201) may stop comparing the voltage from the second battery (101-2) with the second reference voltage (e.g., 2.8 V) when charging the first battery (101-1) using the boosted voltage obtained (or applied) from the boosting circuit (205). For example, the PMIC (201) may change the reference voltage at which charging is stopped to another reference voltage while connected to the external power source. For example, the other reference voltage may be higher than the second reference voltage.
[0110] For example, the PMIC (201) can maintain the shipping mode (107) based on the voltage from the second battery (101-2) that is lower than the other reference voltage. For example, the PMIC (201) can switch the mode of the electronic device (100) from the shipping mode (107) to another mode based on the voltage from the second battery (101-2) that is higher than the other reference voltage. Based on the switching, the one or more load electrical components (207) and the PMIC (201) can be electrically connected. The PMIC (201) can change the signal in the second state to the signal in the first state based on the voltage of the second battery (101-2) that is higher than the other reference voltage. The PMIC (201) can transmit the signal in the first state to the boosting circuit (205).
[0111] FIG. 3 illustrates a chart representing changes in the voltage of a first battery and changes in the voltage of a second battery in an electronic device having individual charging structures based on the passage of time.
[0112] Referring to FIG. 3, the chart (300) represents changes in voltage magnitude over time. The horizontal axis within the chart (300) represents time, and the vertical axis within the chart (300) represents voltage magnitude. Within the time axis of the chart (300), it is assumed that the electronic device (100) is not being charged.
[0113] The first voltage (301-1) may be referred to as a reference voltage (e.g., a first reference voltage) of the power-off mode (105). The second voltage (301-2) may be referred to as a reference voltage (e.g., a second reference voltage) of the shipping mode (107). The third voltage (301-3) may be referred to as a voltage at which the swelling phenomenon of the first battery (101-1) and the second battery (101-2) is accelerated (or occurs).
[0114] The first point in time (303-1) may be referred to as the point in time when the power off mode (105) is switched to the shipping mode (107). The second point in time (303-2) may be referred to as the point in time when the charging of the second battery (101-2) is stopped within the shipping mode (107). The third point in time (303-3) may be referred to as the point in time when the swelling phenomenon of the first battery (101-1) and the second battery (101-2) is accelerated within the shipping mode (107).
[0115] The first section (305-1) may refer to a period corresponding to the power off mode (105). The second section (305-2) may refer to a period during which the second battery (101-2) is being charged within the shipping mode (107). The third section (305-3) may refer to a period during which charging of the second battery (101-2) is stopped within the shipping mode (107). The solid line of the chart (300) may represent the voltage of the first battery (101-1). The dotted line of the chart (300) may represent the voltage of the second battery (101-2).
[0116] The voltage of the first battery (101-1) and the voltage of the second battery (101-2) may be reduced below the first voltage (301-1) at at least one point in time within the first section (305-1). Based on the voltage of the first battery (101-1) and the voltage of the second battery (101-2) being reduced below the first voltage (301-1), the mode of the electronic device (100) may be switched from the power on mode (103) to the power off mode (105).
[0117] In the first section (305-1), the voltage of the first battery (101-1) and the voltage of the second battery (101-2) can be reduced at the same rate.
[0118] At the first point in time (303-1), the voltages of the first battery (101-1) and the second battery (101-2) may be reduced to the second voltage (301-2). Based on the reduction of the voltage of the first battery (101-1) and the voltage of the second battery (101-2) to the second voltage (301-2), the mode of the electronic device (100) may be switched from the power-off mode (105) to the shipping mode (107).
[0119] According to one embodiment, in the second section (305-2) (or when switching from the power mode (105) to the shipping mode (107)), the PMIC (201) can transmit a signal in the second state to the boosting circuit (205). In response to the signal in the second state, the boosting circuit (205) can boost the voltage provided from the first battery (101-1). The boosting circuit (205) can provide the boosted voltage to the PMIC (201). Based on the PMIC (201) providing the boosted voltage obtained (or applied) from the boosting circuit (205) to the second battery (101-2), the second battery (101-2) can be charged.
[0120] In the second section (305-2), the voltage of the second battery (101-2) may increase based on the charging of the second battery (101-2). In the second section (305-2), the voltage of the first battery (101-1) may decrease based on the charging. As the second battery (101-2) is charged, the magnitude of the current input to the second battery (101-2) may gradually decrease within the second section (305-2).
[0121] For example, at the second time point (303-2), based on the fact that the charge amount of the second battery (101-2) is higher than the reference charge amount, the PMIC (201) can change the signal in the second state into a signal in the first state and transmit it to the boosting circuit (205). For example, at the second time point (303-2), the magnitude of the current input to the second battery (101-2) can decrease below a specified current for stopping charging of the second battery (101-2). The PMIC (201), which identifies the current that has decreased below the specified current, can change the signal in the second state transmitted to the boosting circuit (205) into a signal in the first state. In response to the signal in the second state, the boosting circuit (205) can stop boosting the voltage of the first battery (101-1).
[0122] The voltage reduction rate of the first battery (101-1) and the voltage reduction rate of the second battery (101-2) may be different. For example, in the third section (305-3), the voltage reduction rate of the second battery (101-2) may be twice the voltage reduction rate of the first battery (101-1).
[0123] After the charging is stopped, the voltage of the second battery (101-2) may be higher than the voltage of the first battery (101-2). Depending on the voltage of the second battery (101-2), the discharge period until the voltage at which the swelling phenomenon of the second battery (101-2) is accelerated may increase. Accordingly, at the third time point (303-3), the voltage of the first battery (101-1) and the voltage of the second battery (101-2) may be the third voltage (301-3). For example, at the third time point (303-3), the difference between the voltage of the first battery (101-1) and the voltage of the second battery (101-2) may be less than a certain voltage. The certain voltage may be a voltage with a relatively small value. For example, the third voltage (301-3) may be a voltage at which the swelling phenomenon of the first battery (101-1) and the second battery (101-2) is accelerated.
[0124] Based on the charging of the second battery (101-2) in the second section (305-2), the point in time at which the swelling phenomenon of the second battery (101-2) accelerates may be delayed to a third point in time (303-3). That is, both the first battery (101-1) and the second battery (101-2) may enter a state in which the swelling phenomenon accelerates from the third point in time (303-3).
[0125] FIG. 4 illustrates a chart representing the change in capacity of a first battery and a second battery of an electronic device having individual charging structures based on the passage of time.
[0126] Referring to FIG. 4, a chart (400) represents changes in the capacity of a first battery (101-1) and a second battery (101-2) over time. The horizontal axis in the chart (400) represents time, and the vertical axis in the chart (400) represents the capacity of the batteries. Within the time axis of the chart (400), it is assumed that the electronic device (100) is not being charged.
[0127] The first point in time (403-1), the second point in time (403-2), and the third point in time (403-3) may be the same as or similar to the first point in time (303-1), the second point in time (303-2), and the third point in time (303-3) of FIG. 3, respectively. The first section (405-1), the second section (405-2), and the third section (405-3) may be the same as or similar to the first section (305-1), the second section (305-2), and the third section (305-3) of FIG. 3, respectively.
[0128] The first capacity (401-1) (e.g., about 30 mAh) may be referred to as the capacity of the first battery (101-1) at a point in time when the voltage of the first battery (101-1) is a first reference voltage (e.g., about 3.4 V).
[0129] The second capacity (401-2) (e.g., about 20 mAh) may be referred to as the capacity of the first battery (101-1) at a point in time when the voltage of the first battery (101-1) is a second reference voltage (e.g., about 2.8 V).
[0130] The third capacity (401-3) (e.g., about 10 mAh) may be referred to as the capacity of the first battery (101-1) at the point in time when charging from the first battery (101-1) to the second battery (101-2) begins. The third capacity (401-3) (e.g., about 10 mAh) may be referred to as the capacity of the second battery (101-2) at the second reference voltage.
[0131] The solid line of the above chart (400) may represent the capacity of the first battery (101-1). The dotted line of the above chart (400) may represent the capacity of the second battery (101-2). The capacity may refer to the remaining capacity of the battery. The capacity may be proportional to the remaining capacity of the battery. The capacity may refer to the charge amount of the battery. The capacity may be proportional to the charge amount of the battery. The capacity may refer to the current amount of the battery. The capacity may be proportional to the current amount of the battery.
[0132] In the first section (405-1), the capacity of the first battery (101-1) may be reduced from the first capacity (401-1) to the second capacity (401-2). In the first section (405-1), the capacity of the second battery (101-2) may be reduced from the second capacity (401-2) to the third capacity (401-3). For example, the second capacity (401-2) may be twice the third capacity (401-3).
[0133] At at least one point in time within the first section (405-1), the electronic device (100) can be switched from a power on mode (103) to a power off mode (105).
[0134] At the first point in time (403-1), the electronic device (100) may be switched from a power-off mode (105) to a shipping mode (107). For example, at the second section (405-2), the PMIC (201) may transmit a signal within the second state to the boosting circuit (205). In response to the signal, the boosting circuit (205) may boost a voltage provided from the first battery (101-1). The boosting circuit (205) may provide the boosted voltage to the PMIC (201).
[0135] In the second section (405-2), the second battery (101-2) may be charged based on the PMIC (201) providing the boosted voltage obtained (or applied) from the boosting circuit (205) to the second battery (101-2). For example, within the second section (405-2), based on the charging, the capacity of the second battery (101-2) may be increased. For example, within the second section (405-2), based on the charging, the capacity of the first battery (101-1) may be decreased.
[0136] For example, at the second point in time (403-2), the capacity of the first battery (101-1) may be the third capacity (401-3). At the second point in time (403-2), the capacity of the first battery (101-1) may be the second capacity (401-2).
[0137] At a second point in time (403-2), the second battery (101-2) may be charged by a reference charge amount based on the charging. The second capacity (401-2) may be referred to as the reference charge amount. The reference charge amount may be set so that both the first battery (101-1) and the second battery (101-2) enter a state in which the swelling phenomenon is accelerated at the same point in time (e.g., at a third point in time (403-3)).
[0138] At the second point in time (403-2), based on the fact that the charge amount of the second battery (101-2) is higher than the reference charge amount, the PMIC (201) can change the signal in the second state into a signal in the first state. The PMIC (201) can transmit the signal in the first state. In response to the signal in the first state, the boosting circuit (205) can stop boosting the voltage of the first battery (101-1).
[0139] For example, at the second time point (403-2), the rate of decrease in capacity of the second battery (101-2) may be twice the rate of decrease in capacity of the first battery (101-1). The capacity of the second battery (101-2) may be twice that of the first battery (101-1) at the second time point (403-2). Accordingly, the time point at which the capacity of the first battery (101-1) decreases to become the first reference capacity and the time point at which the capacity of the second battery (101-2) decreases to become the second reference capacity may be the same or similar. As the first battery (101-1) has the first reference capacity, the swelling phenomenon of the first battery (101-1) may be accelerated. As the second battery (101-2) has the second reference capacity, the swelling phenomenon of the second battery (101-2) may be accelerated.
[0140] At the third point in time (405-3), the first battery (101-1) may have the first reference capacity. The second battery (101-2) may have the second reference capacity.
[0141] The voltage of the first battery (101-1) according to the first reference capacity may be referred to as a voltage at which the swelling phenomenon of the first battery (101-1) is accelerated. The voltage of the second battery (101-2) according to the second reference capacity may be referred to as a voltage at which the swelling phenomenon of the second battery (101-2) is accelerated.
[0142] Based on the second battery (101-2) being charged in the second section (405-2), the point in time at which the capacity of the second battery (101-2) decreases to a capacity at which the swelling phenomenon accelerates may be delayed to a third point in time (403-3).
[0143] FIG. 5 illustrates exemplary operations of an electronic device for charging a second battery using at least one power management circuit.
[0144] Referring to FIG. 5, in operation 501, at least one power management circuit (200) may compare a voltage associated with the first battery (101-1) and a voltage associated with the second battery (101-2) with the second reference voltage (e.g., about 2.8 V) while the electronic device (100) is in a power-off state (105) of the electronic device (100).
[0145] In operation 503, the at least one power management circuit (200) can identify whether the voltage associated with the first battery and the voltage associated with the second battery (101-2) are lower (or higher) than the second reference voltage.
[0146] In operation 505, based on the voltage associated with the first battery (101-1) and the voltage associated with the second battery (101-2) being lower than a second reference voltage, the at least one power management circuit (200) can electrically disconnect the one or more load electrical components (207) from the first battery (101-1) and the second battery (101-2).
[0147] In operation 507, based on the voltage associated with the first battery (101-1) and the voltage associated with the second battery (101-2) being higher than a second reference voltage, the at least one power management circuit (200) can maintain electrical connection of the one or more load electrical components (207) from the first battery (101-1) and the second battery (101-2).
[0148] In operation 509, the at least one power management circuit (200) can provide power from the first battery (101-1) to the second battery (101-2) to charge the second battery (101-2) by boosting the voltage of the first battery (101-1).
[0149] FIG. 6 illustrates exemplary operations of an electronic device for charging a secondary battery using a boosting circuit since entering a shipping mode.
[0150] Referring to FIG. 6, in operation 601, the switching circuit (203) may compare the voltage from the first battery (101-1) with a reference voltage. Operation 601 may be performed to determine whether to enter the power-on mode (103) into the power-off mode (105).
[0151] For example, while the voltage from the first battery (101-1) and the voltage from the second battery (101-2) are below a first reference voltage, power supply to one or more load electrical components (207) electrically connected to the PMIC (201) may be stopped. The mode of the electronic device (100) may be switched from a power on mode (103) to a power off mode (105). While switched to the power off mode (105), the switching circuit (203) may compare the voltage from the first battery (101-1) electrically connected to the switching circuit (203) with a second reference voltage (e.g., about 2.8 V) for entering the shipping mode (107).
[0152] In operation 603, the switching circuit (203) may electrically disconnect the one or more load electrical components (207) from the switching circuit (203) to enter a shipping mode (107) based on the voltage from the first battery (101-1) being lower than the reference voltage. For example, based on the voltage from the first battery (101-1) being lower than a second reference voltage (e.g., about 2.6 V), the mode of the electronic device (100) may enter the shipping mode (107) from the power off mode (105). To enter the shipping mode (107), the switching circuit (203) may control the second switch (204) to electrically disconnect the third terminal (204-1) and the fourth terminal (204-2). The above switching circuit (203) can disconnect the electrical connection between the PMIC (201) and the first battery (101-1) through the switching circuit (203) based on the control of the second switch (204).
[0153] In operation 605, the PMIC (201) may compare the voltage from the second battery (101-2) with the reference voltage (e.g., a reference voltage for entering the power-on mode (103) into the power-off mode (105). For example, while the voltage from the first battery (101-1) and the voltage from the second battery (101-2) are lower than or equal to the first reference voltage, the PMIC (201) may perform operation 607.
[0154] In operation 607, the PMIC (201) may electrically disconnect the one or more load electrical components (207) from the PMIC (201) to enter the shipping mode (107) based on the voltage from the second battery (101-2) being lower than the reference voltage. For example, the PMIC (201) may control the first switch (202) based on the voltage from the second battery (101-2) being lower than a second reference voltage (e.g., 2.5 V). Based on the control, the PMIC (201) may electrically disconnect the first terminal (202-1) and the second terminal (202-1). Accordingly, the PMIC (201) may disconnect the electrical connection with the first battery (101-1) based on the switching circuit (203).
[0155] In operation 609, the PMIC (201) can change the state of a signal transmitted from the PMIC (201) to the boosting circuit (205) (e.g., a signal transmitted through the signal path (209) of FIG. 2) from a first state to a second state. For example, after a reference time has elapsed since the PMIC (201) was electrically disconnected from the first battery (101-1), the PMIC (201) can change the signal within the first state to the signal within the second state.
[0156] In operation 611, the PMIC (201) can transmit the signal in the second state to the boosting circuit (205) through the signal path (209).
[0157] In operation 613, the boosting circuit (205) can boost the voltage from the first battery (101-1) in response to the signal within the second state.
[0158] In operation 615, the boosting circuit (205) can provide the boosted voltage to the PMIC (201).
[0159] In operation 617, the PMIC (201) can charge the second battery (101-2) using the boosted voltage obtained (or applied) from the boosting circuit (205). For example, the PMIC (201) can charge the second battery (101-2) using the boosted voltage obtained (or applied) from the boosting circuit (205) by electrically connecting the first terminal (202-1) and the second terminal (202-2) that were electrically disconnected in operation 607. Charging of the second battery (101-2) based on operation 617 can be maintained or stopped based on the voltage, charge amount, and / or current of the second battery (101-2). For example, the PMIC (201) may compare the magnitude of the current input to the second battery (101-2) with a designated current. As the second battery (101-2) is charged, the magnitude of the current input to the second battery (101-2) may decrease. The PMIC (201) may, based on detecting that the magnitude of the current input to the second battery (101-2) decreases below the designated current, at least temporarily stop charging the second battery (101-2) based on operation 617.
[0160] Figure 7 illustrates exemplary operations of an electronic device in which a boosting circuit stops boosting voltage.
[0161] Referring to FIG. 7, in operation 701, the PMIC (201) can identify the charge amount of the second battery (101-2) according to the boosted voltage obtained (or applied) from the boosting circuit (205) while charging the second battery (101-2) using the boosted voltage obtained (or applied) from the boosting circuit (205).
[0162] In operation 703, the PMIC (201) can compare the reference charge amount for switching the shipping mode (107) to another mode of the electronic device (100) with the charge amount provided from the second battery (101-2) according to the boosted voltage.
[0163] The PMIC (201) can maintain the signal in the second state based on the charge amount of the second battery (101-2) that is lower than the reference charge amount in the shipping mode (107). The PMIC (201) can perform an operation of identifying the charge amount according to the boosted voltage, which is referred to as operation 701.
[0164] In operation 705, the PMIC (201) can change the signal in the second state to the signal in the first state based on the charge amount of the second battery (101-2) being greater than the reference charge amount.
[0165] In operation 707, the PMIC (201) can transmit the signal in the first state to the boosting circuit (205).
[0166] In operation 709, the boosting circuit (205) may stop boosting the voltage from the first battery (101-1) in response to the signal within the first state.

[0178] The first switching circuit (203-1) can provide power of the first battery (101-1) to one or more load electrical components (207). The second switching circuit (203-2) can provide power of the third battery (101-3) to one or more load electrical components (207). As the power of the first battery (101-1), the power of the second battery (101-2), and the power of the third battery (101-3) are provided to the one or more load electrical components (207), the voltage of the first battery (101-1), the voltage of the second battery (101-2), and the voltage of the third battery can be lowered. Based on the voltage of the first battery (101-1), the voltage of the second battery (101-2), and the voltage of the third battery (101-3) being lower than a first reference voltage (e.g., about 3.4 V), the mode of the electronic device (100) can be switched from the power on mode (103) to the power off mode (105).
[0179] Below, the operations of the electronic device (100) in the power off mode (105) are described. Descriptions overlapping with the operations of the electronic device (100) of FIG. 2 are omitted.
[0180] In the power off mode (105), the first switching circuit (203-1) may stop providing power of the first battery (101-1) to the one or more load electrical components (207). The second switching circuit (203-2) may stop providing power of the third battery (101-3) to the one or more load electrical components (207).
[0181] In the power off mode (105), the power of the first battery (101-1), the power of the second battery (101-2), and the power of the third battery (101-3) may be discharged. As the power of the first battery (101-1), the power of the second battery (101-2), and the power of the third battery (101-3) are discharged, the voltage of the first battery (101-1), the voltage of the second battery (101-2), and the voltage of the third battery may decrease.
[0182] The electronic device (100) can compare the voltage of the first battery (101-1), the voltage of the second battery (101-2), and the voltage of the third battery (101-3) with a second reference voltage (e.g., about 2.8 V). Based on the voltage of the first battery (101-1), the voltage of the second battery (101-2), and the voltage of the third battery (101-3) decreasing below the second reference voltage, the mode of the electronic device (100) can be switched from the power off mode (105) to the shipping mode (107).
[0183] Below, the operations of the electronic device (100) within the shipping mode (107) are described. Descriptions overlapping with those of the electronic device (100) of Fig. 2 are omitted.
[0184] The voltage of the first battery (101-1) may be lower than the second reference voltage. Based on the voltage of the first battery (101-1), the mode of the electronic device (100) may enter the shipping mode (107). Based on entering the shipping mode (107), the first switching circuit (203-1) may control the second switch (204) to electrically disconnect the third terminal (204-1) and the fourth terminal (204-2). The first switching circuit (203-1) may disconnect the electrical connection between the one or more load electrical components (207) based on the control of the second switch (204).
[0185] Based on the voltage of the third battery (101-3) being lower than the second reference voltage, the mode of the electronic device (100) may enter the shipping mode (107). Based on entering the shipping mode (107), the second switching circuit (203-2) may control the third switch (206) to electrically disconnect the fifth terminal (206-1) and the sixth terminal (206-2). The second switching circuit (203-2) may disconnect the electrical connection between the one or more load electrical components (207) based on the control of the third switch (206).

Based on the switching, the PMIC (201) can change a signal in the first state into a signal in the second state. The PMIC (201) can transmit the signal in the second state. In response to the signal in the second state, the first boosting circuit (205-1) can boost the voltage from the first battery (101-1) electrically connected to the first boosting circuit (205-1).
[0187] The mode of the electronic device (100) can be switched from the power-off mode (105) to the shipping mode (107). The PMIC (201) can change a signal in the first state into a signal in the second state. The PMIC (201) can transmit the signal in the second state to the second boosting circuit (205-2). In response to the signal in the second state, the second boosting circuit (205-2) can boost the voltage from the third battery (101-3) electrically connected to the second boosting circuit (205-2).
[0188] The PMIC (201) may be configured to provide power received from the first boosting circuit (205-1) and the second boosting circuit (205-2) to the second battery (101-2) by using the boosted voltage obtained (or applied) from the first boosting circuit (205-1) and the second boosting circuit (205-2).
[0189] In the shipping mode (107), the PMIC (201) can control the first switch (202) to electrically connect between the first terminal (202-1) and the second terminal (202-2) only while the power received from the first boosting circuit (205-1) and the second boosting circuit (205-2) is provided to the second battery (101-2). Charging of the second battery (101-2) can be performed based on the power provided from the PMIC (201).
[0190] Within the shipping mode (107), charging of the second battery (101-2) using the first battery (101-1) and the third battery (101-3) may be maintained or stopped based on at least one of the reference charge amount, reference remaining amount, and / or reference current amount of the second battery (101-2).
[0191] The PMIC (201) can identify the charge amount of the second battery (101-2) while the charging is being performed. Based on the charge amount of the second battery (101-2) becoming higher than the reference charge amount, the PMIC (201) can change the signal in the second state into the signal in the first state. The PMIC (201) can change the signal in the second state into the signal in the first state and transmit it to the first boosting circuit (205-1) and the second boosting circuit (205-2).
[0192] The PMIC (201) can identify the remaining amount of the second battery (101-2) while the charging is being performed. Based on the fact that the charge amount of the second battery (101-2) becomes higher than the reference remaining amount, the PMIC (201) can change the signal in the second state into the signal in the first state. The PMIC (201) can change the signal in the second state into the signal in the first state and transmit it to the first boosting circuit (205-1) and the second boosting circuit (205-2).
[0193] The PMIC (201) can identify the current amount of the second battery (101-2) while the charging is being performed. Based on the current amount of the second battery (101-2) becoming higher than the reference current amount, the PMIC (201) can change the signal in the second state into the signal in the first state. The PMIC (201) can change the signal in the second state into the signal in the first state and transmit it to the first boosting circuit (205-1) and the second boosting circuit (205-2).
[0194] In response to the signal within the first state, the first boosting circuit (205-1) can stop boosting the voltage from the first battery (101-1). In response to the signal within the first state, the second boosting circuit (205-2) can stop boosting the voltage from the third battery (101-3).
[0195] In one embodiment, the electronic device (100) may establish a connection with an external power source. Hereinafter, the operation of the electronic device (100) in the power-on mode (103), the power-off mode (105), and the shipping mode (107) based on the connection will be described. Descriptions overlapping with the operation of the electronic device (100) of FIG. 2 will be omitted.
[0196] As the external power source is connected through the port (217), the voltage provided from the PMIC (201) may be higher than the first reference voltage. Based on the voltage, the mode of the electronic device (100) may be switched from the shipping mode (107) to the power on mode (103) or the power off mode (105). Based on the voltage, the second switching circuit (203-2) may control the third switch (206) to electrically connect the fifth terminal (206-1) and the sixth terminal (206-2). The second switching circuit (203-2) may provide power of the third battery (101-3) to the one or more load electrical components (207) based on the control of the third switch (206).
[0197] As the external power source is connected through the wireless charging circuit, the voltage provided from the PMIC (201) may become higher than the first reference voltage. Based on the voltage, the mode of the electronic device (100) may be switched from the shipping mode (107) to the power on mode (103) or the power off mode (105). Based on the switching, the second switching circuit (203-2) may control the third switch (206) to electrically connect the fifth terminal (206-1) and the sixth terminal (206-2). The second switching circuit (203-2) may provide power of the third battery (101-3) to the one or more load electrical components (207) based on the control of the third switch (206).
[0198] In one embodiment, the PMIC (201) may charge the second battery (101-2) using the boosted voltage obtained (or applied) from the first boosting circuit (205-1) and the second boosting circuit (205-2). The voltage of the second battery (101-2) may increase based on the charging. The electronic device (100) may be designed to stop the charging based on the increase in the voltage of the second battery (101-2). According to the stop, the charging of the second battery (101-2) may be stopped before being charged to a reference charge amount. Accordingly, while the charging is in progress, a change in the reference voltage for the stop may be required. Hereinafter, an operation of changing the reference voltage of the PMIC (201) is described.
[0199] The PMIC (201) may compare the voltage from the second battery (101-2) with another reference voltage (e.g., about 3.0 V) that is different from the second reference voltage (e.g., about 2.8 V) while charging the second battery (101-2) using the boosted voltage obtained (or applied) from the first boosting circuit (205-1) and the second boosting circuit (205-2). For example, the other reference voltage may be higher than the second reference voltage.
[0200] For example, the PMIC (201) can maintain the shipping mode (107) based on the voltage from the second battery (101-2) that is lower than the other reference voltage. For example, the PMIC (201) can switch the mode of the electronic device (100) from the shipping mode (107) to another mode of the electronic device (100) based on the voltage from the second battery (101-2) that is higher than the other reference voltage. Based on the switching, the one or more load electrical components (207) and the PMIC (201) can be electrically connected. The PMIC (201) can change the signal in the second state to the signal in the first state based on the voltage from the second battery (101-2) that is higher than the other reference voltage. The PMIC (201) can transmit the signal within the first state to the first boosting circuit (205-1) and the second boosting circuit (205-2), respectively.

[0203] The first node (211) of the electronic device (100) may be identical to or similar to the first node (211) of FIG. 2. The second node (213) of the electronic device (100) may be identical to or similar to the second node (213) of the electronic device (100) of FIG. 2.

The first battery (101-1) and the second battery (101-2) may be identical to or similar to the first battery (101-1) and the second battery of FIG. 2. The switching circuit (203) may be identical to or similar to the switching circuit (203) of FIG. 2. The boosting circuit (205) may be identical to or similar to the boosting circuit (205) of FIG. 2. The one or more load electrical components (207) may be identical to or similar to the one or more load electrical components (207) of FIG. 2. The first signal path (901) may be identical to or similar to the signal path (209) of FIG. 2.
[0204] Referring to Fig. 9, the PMIC (201) may be connected to the boosting circuit (205) through the first signal path (901). The PMIC (201) may be connected to the switching circuit (203) through the third signal path (905). The switching circuit (203) may be connected to the boosting circuit (205) through the second signal path (903).
[0205] The PMIC (201) can transmit a signal in a first state or a signal in a second state using the first signal path (901). The PMIC (201) can transmit a signal in a first state or a signal in a second state using the second signal path (903). The PMIC (201) can transmit the signal in the first state or the signal in the second state using the third signal path (905). The PMIC (201) can receive the signal in the first state or the signal in the second state using the third signal path (905). The PMIC (201) can receive information about the state of the first battery (e.g., the remaining capacity of the first battery (101-1)) using the third signal path (905).
[0206] The above switching circuit (203) can transmit the signal within the first state or the signal within the second state by using the boosting circuit (205) and the second signal path (903).
[0207] Within the power-on mode (103), the operation of the electronic device (100) is exemplified in the operation of the electronic device (100) of FIG. 2. Within the power-off mode (105), the operation of the electronic device (100) is exemplified in the operation of the electronic device (100) of FIG. 2.
[0208] To explain operations for charging the second battery (101-2) using the first signal path (901), the second signal path (903), and the third signal path (905) within the shipping mode (107), FIGS. 10 and 11 are illustrated.
[0209] FIG. 10 illustrates exemplary operations of an electronic device for charging a second battery via a boosted voltage according to a signal transmitted using signal paths.
[0210] Referring to FIG. 10, the switching circuit (203) may compare the voltage from the first battery (101-1) to a reference voltage while ceasing to provide power to one or more load electrical components (207) in operation 1001. Operation 1001 may be performed while the first battery and the second battery are in a power-off mode (e.g., while the voltage from the first battery (101-1) is less than or equal to a first reference voltage (e.g., about 3.4 V)). The reference voltage of operation 1001 may be a second reference voltage (e.g., about 2.8 V) that is less than or equal to the first reference voltage and indicates a transition to a shipping mode. When the voltage of the first battery decreases below the reference voltage, the switching circuit (203) may perform operation 1003.
[0211] In operation 1003, the switching circuit (203) may enter the delivery mode (107) based on the voltage from the first battery (101-1) being lower than the reference voltage. The switching circuit (203) may electrically disconnect the one or more load electrical components (207) from the switching circuit (203). For example, the switching circuit (203) may enter the delivery mode (107) based on the voltage from the first battery (101-1) being lower than the second reference voltage. Based on the entry, the switching circuit (203) may control the second switch (204) to disconnect the electrical connection between the third terminal (204-1) and the fourth terminal (204-2). The above switching circuit (203) can disconnect the electrical connection between the first battery (101-1) and the PMIC (201) through the switching circuit (203) based on the control of the second switch (204).
[0212] In operation 1005, the switching circuit (203) can transmit a signal to the boosting circuit (205) using the second signal path (903) based on disconnecting the electrical connection between the first battery (101-1) and the PMIC (201) through the switching circuit (203).
[0213] In operation 1007, the boosting circuit (205) can boost the voltage from the first battery (101-1) in response to a signal received from the switching circuit (203). For example, the switching circuit (203) can change a signal in a first state into a signal in a second state. The switching circuit (203) can transmit the signal in the second state to the boosting circuit (205). In response to the signal, the boosting circuit (205) can boost the voltage of the first battery (101-1).
[0214] In operation 1009, the boosting circuit (205) can provide the boosted voltage to the PMIC (201).
[0215] In operation 1011, the PMIC (201) can charge the second battery (101-2) using the boosted voltage obtained (or applied) from the boosting circuit (205). The operation of charging the second battery (101-2) is exemplified in the description of FIG. 6.
[0216] FIG. 11 illustrates exemplary operations of an electronic device that stops charging a second battery in response to a signal transmitted using signal paths.
[0217] Operations 1101 to 1117 of FIG. 11 may be executed after operations 1001 to 1011 of FIG. 10 are executed.
[0218] Referring to FIG. 11, in operation 1101, the switching circuit (203) can identify the charge amount of the first battery (101-1).
[0219] In operation 1103, the switching circuit (203) can transmit information including the charge amount of the first battery (101-1) to the PMIC (201) through the third signal path (905).
[0220] In operation 1105, the PMIC (201) can identify the charge amount of the second battery (101-2).
[0221] In operation 1107, the PMIC (201) may determine a reference charge amount based on the charge amount of the second battery (101-2) and the charge amount of the first battery (101-1). For example, the PMIC (201) may determine a reference charge amount based on the charge amount of the first battery (101-1) and the charge amount of the second battery (101-2) so that the time at which the battery swelling phenomenon of the first battery (101-1) is accelerated and the time at which the battery swelling phenomenon of the second battery (101-2) is accelerated are substantially the same. For example, the PMIC (201) can determine a reference charge amount based on the charge amount of the first battery (101-1) and the charge amount of the second battery (101-2), such that the difference period between the time at which the battery swelling phenomenon of the first battery (101-1) is accelerated and the time at which the battery swelling phenomenon of the second battery (101-2) is accelerated is substantially less than a certain period of time.
[0222] For example, the second battery (101-2) may be charged from the first battery (101-1). As the second battery (101-2) is charged to the reference charge amount, the charging may be stopped. After the charging is stopped, the first battery (101-1) and the second battery (101-2) may be discharged. Based on the discharging, the voltage of the first battery (101-1) and the voltage of the second battery (101-2) may be discharged to a voltage at which a swelling phenomenon is accelerated. After the charging is stopped, as the discharging progresses, the time at which the battery swelling phenomenon of the first battery (101-1) is accelerated and the time at which the battery swelling phenomenon of the second battery (101-2) is accelerated may be substantially the same. After the above charging is stopped, as the above discharge proceeds, the difference period between the time at which the battery swelling phenomenon of the first battery (101-1) is accelerated and the time at which the battery swelling phenomenon of the second battery (101-2) is accelerated may be less than a certain period of time.
[0223] In operation 1109, the PMIC (201) can identify the charge amount of the second battery (101-2) according to the boosted voltage obtained (or applied) from the boosting circuit (205).
[0224] In operation 1111, the PMIC (201) may compare the reference charge amount with the charge amount of the second battery (101-2). For example, the PMIC (201) may perform an operation of identifying the charge amount of the second battery (101-2), referred to as operation 1105, based on the charge amount of the second battery (101-2) being lower than the reference charge amount (e.g., lower than or equal to the reference charge amount) for switching the shipping mode (107) to another mode of the electronic device (100).
[0225] In operation 1113, the PMIC (201) may change the signal in the second state to a signal in the first state based on a charge amount of the second battery (101-2) that is higher than the reference charge amount (e.g., exceeds the reference charge amount or is equal to or greater than the reference charge amount).
[0226] In operation 1115, the PMIC (201) can transmit the signal within the first state to the boosting circuit (205).
[0227] In operation 1117, the boosting circuit (205) may stop boosting the voltage from the first battery (101-1) in response to receiving the signal within the first state.

Within the power-off mode (105), the operation of the electronic device (100) is exemplified in the operation of the electronic device (100) of FIG. 2.
[0235] Below, the operations of the electronic device (100) within the shipping mode (107) are described.
[0236] Within the shipping mode (107), the voltage of the second battery (101-2) may be lower than the second reference voltage. Based on the voltage, the mode of the electronic device (100) may enter the shipping mode (107). The PMIC (201) may control the first switch (202) to electrically disconnect the first terminal (202-1) and the second terminal (202-2). The PMIC (201) may disconnect the electrical connection between the one or more load electrical components (207) based on the control of the first switch (202).
[0237] The voltage of the first battery (101-1) may be lower than the second reference voltage. Based on the voltage, the mode of the electronic device (100) may enter the shipping mode (107) from another mode of the electronic device (100). Based on the entry, the switching circuit (203) may control the second switch (204) to electrically disconnect the third terminal (204-1) and the fourth terminal (204-2). The switching circuit (203) may disconnect the electrical connection between the one or more load electrical components (207) based on the control of the second switch (204).
[0238] The PMIC (201) can change the state of a signal transmitted from the PMIC (201) to the switching circuit (203) to electrically connect the first battery (101-1) to the PMIC (201) from a first state to a second state based on identifying that a reference time has elapsed since the PMIC (201) was electrically disconnected from the one or more load electrical components (207).
[0239] The switching circuit (203) can electrically connect the first battery (101-1) and the PMIC (201) using the second switch (204) in response to the signal within the second state. The PMIC (201) can identify a voltage from the first battery (101-1) based on the electrical connection. The PMIC (201) can compare the voltage from the first battery (101-1) with a threshold voltage (e.g., about 1.53 V). The PMIC (201) can electrically disconnect the one or more load electrical components (207) from the switching circuit (203) based on the voltage from the first battery (101-1) being lower than the threshold voltage.

As the third terminal (204-1) and the fourth terminal (204-2) are electrically connected, the first battery (101-1) can be electrically connected to the PMIC (201). The PMIC (201) can be electrically connected to the switching circuit (203) by controlling the first switch (202) to electrically connect the first terminal (202-1) and the second terminal (202-2).
[0241] The PMIC (201) can charge the second battery (101-2) using the voltage obtained from the first battery (101-1) through the voltage provided from the switching circuit (203). For example, the PMIC (201) can include a power regulator (e.g., LDO regulator) for adjusting the voltage provided from the first battery (101-1) to be suitable for the charging voltage of the second battery (101-2). Using the adjusted voltage, the PMIC (201) can charge the second battery (101-2).
[0242] The operation of the electronic device (100), based on the electronic device (100) identifying that a connection with an external power source has been established, is exemplified in the description of FIG. 2.
[0243] FIG. 13 illustrates a chart representing changes in the voltage of a first battery and changes in the voltage of a second battery of an electronic device based on the passage of time.
[0244] Referring to FIG. 13, a chart (1300) represents changes in voltage magnitude over time. The horizontal axis within the chart (1300) represents time, and the vertical axis within the chart (1300) represents voltage magnitude. Within the time axis of the chart (1300), it is assumed that the electronic device (100) is not charged.
[0245] The first voltage (1301-1) may be referenced as a reference voltage (e.g., first reference voltage) of the power-off mode (105). The second voltage (1301-2) may be referenced as a reference voltage (e.g., second reference voltage) of the shipping mode (107). The third voltage (1301-3) may be referenced as a voltage at which the swelling phenomenon of the first battery (101-1) and the second battery (101-2) is accelerated.
[0246] The first point in time (1303-1) may be referred to as the point in time when the power off mode (105) is switched to the shipping mode (107). For example, the second point in time (1303-2) may be referred to as the point in time when charging of the second battery (101-2) begins within the shipping mode (107). The third point in time (1303-3) may be referred to as the point in time when the swelling phenomenon of the first battery (101-1) and the second battery (101-2) is accelerated within the shipping mode.
[0247] The first section (1305-1) may refer to a period corresponding to the power off mode (105). The second section (1305-2) may refer to a reference time within the shipping mode (107). The reference time may be referred to as a period during which the second battery (101-2) is discharged to a reference voltage (e.g., about 1.53 V) for electrical connection between the PMIC (201) and the switching circuit (203). The third section (1305-3) may refer to a period during which, within the shipping mode (107), charging of the second battery (101-2) begins to a period during which a swelling phenomenon is accelerated.
[0248] The solid line of the above chart (1300) may represent the voltage of the first battery (101-1). The dotted line of the above chart (1300) may represent the voltage of the second battery (101-2).
[0249] For example, the voltage of the first battery (101-1) and the voltage of the second battery (101-2) may be reduced below the first voltage (1301-1) at at least one point in time within the first section (1305-1). Based on the voltage of the first battery (101-1) being reduced below the first voltage (1301-1), the electronic device (100) may be switched from the power on mode (103) to the power off mode (105).
[0250] In the first section (1305-1), the voltage of the first battery (101-1) and the voltage of the second battery (101-2) can be reduced at substantially the same rate. The power on mode (103) and the power off mode (105) are exemplified in the description of Fig. 1.
[0251] For example, in the first section (1305-1), the voltage of the first battery (101-1) and the voltage of the second battery (101-2) may be reduced to the second voltage (1301-2). For example, in the first section (1305-1), the voltage of the second battery (101-2) may be reduced to the second voltage (1301-2). Based on the reduction of the voltage of the first battery (101-1) and the voltage of the second battery (101-2) to the second voltage (1301-2), the electronic device (100) may be switched from the power off mode (105) to the shipping mode (107).
[0252] Within the second section (1305-2), based on stopping the supply of power to the one or more load electrical components (207), the rate of decrease of the voltage of the first battery (101-1), represented by a solid line, and the rate of decrease of the voltage of the second battery (101-2), represented by a dotted line, may be reduced.
[0253] At the second point in time (1303-2), the voltage of the second battery (101-2) may be discharged to the reference voltage (e.g., approximately 1.53 V). For example, the PMIC (201) may wait to change the state of the signal from the signal in the first state to the signal in the second state until the voltage of the second battery (101-2) at the second point in time (1303-2) becomes the reference voltage. For example, the voltage of the second battery (101-2) at the second point in time (1303-2) may be referenced as a voltage obtained by adding a certain voltage value to the voltage at which the swelling phenomenon is accelerated.
[0254] For example, at the second point in time (1303-2), the PMIC (201) and the first battery (101-1) may be electrically connected. Accordingly, charging of the second battery (101-2) from the first battery (101-1) may begin.
[0255] In the third section (1305-3), the second battery (101-2) can be charged from the first battery (101-1) based on the electrical connection between the PMIC (201) and the switching circuit (203).
[0256] In the third section (1305-3), after the voltage of the first battery (101-1) and the voltage of the second battery (101-2) are lowered below a threshold voltage, the PMIC (201) can change the signal in the second state to a signal in the first state to the switching circuit (203). The PMIC (201) can transmit the signal in the first state to the switching circuit (203). In response to the signal in the first state, the switching circuit (203) can control the second switch (204) to disconnect the electrical connection between the first battery (101-1) and the PMIC (201) through the switching circuit (203).
[0257] For example, after the electrical connection between the first battery (101-1) and the PMIC (201) through the switching circuit (203) is disconnected, in the third section (1303-3), the voltage of the first battery (101-1) and the voltage of the second battery (101-2) may be discharged to the third voltage (1301-3). For example, in the third time point (1303-3), the entire voltage of the first battery (101-1) and the entire voltage of the second battery (101-2) may be discharged to the third voltage (1301-3). For example, at the third point in time (1303-3), after a certain period of time has elapsed since the voltage of the second battery (101-2) has been discharged to the third voltage (1301-3), the voltage of the first battery (101-1) may be discharged to the third voltage (1301-3). The third voltage (1301-3) may be a voltage at which the swelling phenomenon of the first battery (101-1) and the second battery (101-2) is accelerated.
[0258] Based on the charging of the second battery (101-2) in the third section (1305-3), the point in time at which the swelling phenomenon of the second battery (101-2) accelerates can be delayed to the third point in time (1303-3). Accordingly, the life of the second battery (101-2) can be extended.
[0259] FIG. 14 illustrates a chart representing the change in capacity of a first battery and a second battery of an electronic device based on the passage of time.
[0260] Referring to FIG. 14, a chart (1400) represents changes in the capacity of the first battery (101-1) and the capacity of the second battery (101-2) over time. The horizontal axis in the chart (1400) represents time, and the vertical axis in the chart (1400) represents the capacity of the battery. Within the time axis of the chart (1400), it is assumed that the electronic device (100) is not being charged.
[0261] The first point in time (1403-1), the second point in time (1403-2), and the third point in time (1403-3) may be the same as or similar to the first point in time (1303-1), the second point in time (1303-2), and the third point in time (1303-3) of FIG. 3, respectively. The first section (1405-1), the second section (1405-2), and the third section (1405-3) may be the same as or similar to the first section (1305-1), the second section (1305-2), and the third section (1305-3) of FIG. 3, respectively.
[0262] The first capacity (1401-1) (e.g., about 30 mAh) may be referred to as the capacity of the first battery (101-1) at a reference voltage for switching to the power off mode (105). The second capacity (1401-2) (e.g., about 20 mAh) may be referred to as the capacity of the first battery (101-1) at a reference voltage for switching to the shipping mode (107). The third capacity (1401-3) (e.g., about 10 mAh) may be referred to as the capacity of the second battery (101-2) at a reference voltage for switching to the shipping mode (107).
[0263] The solid line of the above chart (1400) may represent the capacity of the first battery (101-1). The dotted line of the above chart (1400) may represent the capacity of the second battery (101-2). The capacity may refer to the remaining capacity of the battery. The capacity may be proportional to the remaining capacity of the battery. The capacity may refer to the amount of charge of the battery. The capacity may be proportional to the amount of charge of the battery. The capacity may refer to the amount of current of the battery. The capacity may be proportional to the amount of current of the battery.
[0264] For example, the mode of the electronic device (100) within the first section (1405-1) may be a power off mode (105).
[0265] At the first point in time (1403-1), the electronic device (100) can be switched from a power off mode (105) to a shipping mode (107).
[0266] For example, after the first time point (1403-1), in the second section (1405-2), the PMIC (201) and the switching circuit (203) may disconnect electrical connection with the one or more load electrical components (207). Based on the disconnection, the capacity reduction rate of the first battery (101-1) and the capacity reduction rate of the second battery (101-2) may be reduced. The capacity reduction rate of the second battery (101-2) may be twice the capacity reduction rate of the first battery (101-1).
[0267] At the second point in time (1403-2), based on the rapid decrease in voltage of the second battery (101-2), the voltage of the second battery (101-2) may reach a reference voltage (e.g., about 1.53 V) for electrical connection of the switching circuit (203) and the PMIC (201). Based on reaching the reference voltage, the switching circuit (203) and the PMIC (201) may be electrically connected.
[0268] In the third section (1405-3), as the switching circuit (203) and the PMIC (201) are electrically connected, the second battery (101-2) can be charged. As the second battery (101-2) is charged, the capacity of the second battery (101-2) can increase, and the capacity of the first battery (101-1) can decrease.
[0269] For example, at at least one point in time within the third section (1405-3), based on a difference between the voltage of the first battery (101-1) and the voltage of the second battery (101-2) being less than a threshold voltage, the electrical connection between the first battery (101-1) and the PMIC (201) through the switching circuit (203) may be disconnected. Based on the disconnection, charging of the second battery (101-2) may be stopped.
[0270] For example, at at least one point in time within the third section (1405-3), the rate of decrease in capacity of the second battery (101-2) may be twice the rate of decrease in capacity of the first battery (101-1). The capacity of the first battery (101-1) may be greater than the capacity of the second battery (101-2). Accordingly, the point in time at which the capacity of the first battery (101-1) decreases to become the first reference capacity and the point in time at which the capacity of the second battery (101-2) decreases to become the second reference capacity may be the same or similar. As the first battery (101-1) has the first reference capacity, the swelling phenomenon of the first battery (101-1) may be accelerated. As the second battery (101-2) has the second reference capacity, the swelling phenomenon of the second battery (101-2) may be accelerated.
[0271] At the third point in time (1405-3), the first battery (101-1) may have the first reference capacity. The second battery (101-2) may have the second reference capacity.
[0272] The voltage of the first battery (101-1) according to the first reference capacity may be referred to as a voltage at which the swelling phenomenon of the first battery (101-1) is accelerated. The voltage of the second battery (101-2) according to the second reference capacity may be referred to as a voltage at which the swelling phenomenon of the second battery (101-2) is accelerated.
[0273] Based on the second battery (101-2) being charged in the third section (1405-3), the point in time at which the capacity of the second battery (101-2) decreases to a capacity at which the swelling phenomenon accelerates may be delayed to the third point in time (403-3).
[0274] FIG. 15 illustrates exemplary operations of an electronic device for charging a second battery using a switching circuit since entering a shipping mode.
[0275] Referring to FIG. 15, in operation 1501, based on stopping the supply of power to the one or more load electrical components (207) electrically connected to the switching circuit (203) and the PMIC (201), the voltage from the first battery (101-1) may be compared with a reference voltage (e.g., a second reference voltage).
[0276] For example, the switching circuit (203) can be switched to the power off mode (105) while the voltage from the first battery (101-1) and the voltage from the second battery (101-2) are lower than or equal to a first reference voltage. While switched to the power off mode (105), the switching circuit (203) can compare the voltage from the first battery (101-1) electrically connected to the switching circuit (203) with a second reference voltage for entering the shipping mode (107).
[0277] In operation 1503, the switching circuit (203) may electrically disconnect the one or more load electrical components (207) from the first battery (101-1) to enter the shipping mode (107) based on the voltage from the first battery (101-1) being lower than the reference voltage.
[0278] For example, the voltage of the first battery (101-1) may be lower than the second reference voltage. Based on the voltage, the switching circuit (203) may enter the second shipment mode (107). The switching circuit (203) may disconnect the electrical connection between the PMIC (201) and the first battery (101-1).
[0279] In operation 1505, the PMIC (201) may compare the voltage from the second battery (101-2) with the reference voltage. For example, the PMIC (201) may be switched to the power off mode (105) while the voltage from the first battery (101-1) and the voltage from the second battery (101-2) are lower than or equal to the first reference voltage. While switched to the power off mode (105), the PMIC (201) may compare the voltage from the second battery (101-2) electrically connected to the PMIC (201) with the second reference voltage for entering the shipping mode (107).
[0280] At operation 1507, the PMIC (201) may electrically disconnect the one or more load electrical components (207) from the PMIC (201) to enter the shipping mode (107) based on the voltage from the second battery (101-2) being lower than the reference voltage.
[0281] For example, the PMIC (201) may disconnect the electrical connection between the PMIC (201) and the first battery (101-1) based on the voltage (e.g., about 2.5 V) from the second battery (101-2) being lower than the second reference voltage.
[0282] In operation 1509, the PMIC (201) can identify that a reference time has elapsed since the PMIC (201) was electrically disconnected from the switching circuit (203) by electrically disconnecting the PMIC (201) from the one or more load electrical components (207).
[0283] For example, the PMIC (201) can determine the period between the time of entering the shipping mode (107) and the time when the voltage from the second battery (101-2) is discharged to about 1.53 V as the reference time.
[0284] However, the voltage that serves as the reference for the point of discharge to the specific voltage described above is not limited to approximately 1.53 V, and may include a voltage for delaying the battery swelling phenomenon.
[0285] In operation 1511, the PMIC (201) can change the signal in the first state transmitted from the PMIC (201) to the switching circuit (203) to the signal in the second state based on the elapse of a reference time.
[0286] For example, the PMIC (201) can change the signal in the first state transmitted from the PMIC (201) to the switching circuit (203) into the signal in the second state based on the second battery (101-2) lowering from about 2.8 V to about 1.53 V.
[0287] In operation 1513, the PMIC (201) can transmit the signal in the second state to the switching circuit (203) through the signal path (1201).
[0288] In operation 1515, the switching circuit (203) may, in response to the signal within the second state, compare the voltage from the first battery (101-1) with a threshold voltage. The threshold voltage may be a reference voltage for initiating charging of the second battery (101-2) based on the first battery (101-1). For example, the switching circuit (203) may, in response to the signal within the second state, compare the voltage from the first battery (101-1) with about 1.55 V.
[0289] For example, the switching circuit (203) may perform an operation of electrically disconnecting one or more load electrical components (207) from the switching circuit (203), referred to as operation 1503, based on the voltage from the first battery (101-1) being lower than the threshold voltage. For example, the switching circuit (203) may be configured to electrically disconnect the one or more load electrical components (207). The switching circuit (203) may be configured to maintain the electrically disconnected state.
[0290] In operation 1517, the switching circuit (203) may electrically connect the first battery (101-1) to the PMIC (201) based on a voltage from the first battery (101-1) that is higher than the threshold voltage. For example, the switching circuit (203) may electrically connect the first battery (101-1) to the PMIC (201) based on a voltage from the first battery (101-1) that is higher than about 1.55 V (e.g., about 1.6 V). The operation of electrically connecting the first battery (101-1) to the PMIC (201) is exemplified within the description of FIG. 12.
[0291] In operation 1519, the switching circuit (203) can provide the voltage from the first battery (101-1) to the second battery (101-2) through an electrical connection between the first battery (101-1) and the PMIC (201). For example, the PMIC (201) can provide a constant voltage to the second battery (101-2) by providing the voltage from the first battery (101-1) to an LDO regulator within the PMIC (201).
[0292] In operation 1521, the PMIC (201) can charge the second battery (101-2) using the voltage provided from the first battery (101-1) to the second battery (101-2) through an electrical connection between the first battery (101-1) and the PMIC (201).
[0293] Figure 16 illustrates exemplary operations of an electronic device to stop a switching circuit from providing voltage.
[0294] Operations 1601 to 1609 of FIG. 16 can be executed after operations 1501 to 1521 of FIG. 15 are executed.
[0295] Referring to FIG. 16, in operation 1601, the PMIC (201) can identify the voltage from the first battery (101-1) and the voltage from the second battery (101-2) while providing the voltage from the first battery (101-1) to the second battery (101-2).
[0296] In operation 1603, the PMIC (201) may compare the difference between the voltage of the first battery (101-1) and the voltage of the second battery (101-2) with a threshold voltage. The threshold voltage may be different from the threshold voltage of operation 1515 of FIG. 15. The threshold voltage of operation 1603 may indicate a condition for stopping charging of the second battery (101-2) based on the first battery (101-1).
[0297] For example, the PMIC (201) may perform an operation of comparing a difference between a voltage from the first battery (101-1) and a voltage from the second battery (101-2), referred to as operation 1601, with a threshold voltage based on the difference being lower than the threshold voltage. For example, the PMIC (201) may maintain the signal in the second state transmitted from the PMIC (201) to the switching circuit (203), based on the difference voltage between the voltage from the first battery (101-1) and the voltage from the second battery (101-2) being higher than about 0.3 V, referred to as the threshold voltage.
[0298] In operation 1605, the PMIC (201) may change the signal in the second state transmitted from the PMIC (201) to the switching circuit (203) to the signal in the first state based on a difference between the voltage from the first battery (101-1) and the voltage from the second battery (101-2) that is lower than the threshold voltage. For example, the signal in the second state transmitted from the PMIC (201) to the switching circuit (203) may be changed to the signal in the first state based on a difference between the voltage from the first battery (101-1) and the voltage from the second battery (101-2) being lower than about 0.3 V referred to as the threshold voltage.
[0299] Referring to operations 1605 and 1607, an embodiment of changing the state of a signal based on a threshold voltage is described, but the embodiment is not limited thereto. For example, when the magnitude of the current input to the second battery (101-2) decreases below the threshold current, the PMIC (201) may change the state of the signal of operation 1605 from the second state to the first state.
[0300] In operation 1607, the PMIC (201) can transmit the signal changed to the first state to the switching circuit (203).
[0301] In operation 1609, the switching circuit (203) can electrically isolate the first battery (101-1) by controlling the second switch (204). For example, the first battery (101-1) can be electrically disconnected from the PMIC (201).
[0302] In operation 1611, the PMIC (201) can electrically isolate the second battery (101-2) by controlling the first switch (202). For example, the second battery (101-2) can be electrically disconnected from other circuits after the first switch (202).
[0303] FIG. 17 is a simplified block diagram of an electronic device for charging a second battery using a switching circuit, including an exemplary third battery and a second switching circuit.
[0304] Referring to FIG. 17, the electronic device (100) may include a PMIC (201), a first switching circuit (203-1), a second switching circuit (203-2), a first battery (101-1), a second battery (101-2), a third battery (101-3), and one or more load electrical components (207).
[0305] Referring to FIG. 17, the PMIC (201) may be identical to or similar to the PMIC (201) of FIG. 12. The first battery (101-1) may be identical to or similar to the first battery (101-1) of FIG. 12. The second battery (101-2) may be identical to or similar to the second battery (101-2) of FIG. 12. The first switching circuit (203-1) and the second switching circuit (203-2) may be identical to or similar to the first switching circuit (203-1) of FIG. 9 and the second switching circuit (203-2) of FIG. 9, respectively. The first signal path (1201-1) and the second signal path (1201-2) may be identical to or similar to the signal path (1201) of FIG. 12.
[0306] The PMIC (201) may be connected to the first switching circuit (203-1) via the first signal path (1201-1). The PMIC (201) may be connected to the second switching circuit (203-2) via the second signal path (1201-2). The third battery (101-3) may be electrically connected to the second switching circuit (203-2).
[0307] The PMIC (201) can transmit a signal in a first state or a signal in a second state to the first switching circuit (203-1) through the first signal path (1201-1). The PMIC (201) can transmit the signal in the first state or the signal in the second state to the second switching circuit (203-2) through the second signal path (1201-2).
[0308] Within the power-on mode (103), the operation of the electronic device (100) is exemplified in the operation of the electronic device (100) of FIG. 8. Within the power-off mode (105), the operation of the electronic device (100) is exemplified in the operation of the electronic device (100) of FIG. 8.
[0309] Below, the operations of the electronic device (100) within the shipping mode (107) are described.
[0310] Within the shipping mode (107), the voltage of the second battery (101-2) may be lower than the second reference voltage. Based on the voltage of the second battery (101-2), the mode of the electronic device (100) may enter the shipping mode (107). Based on entering the shipping mode (107), the PMIC (201) may control the first switch (202) to electrically disconnect the first terminal (202-1) and the second terminal (202-2). The PMIC (201) may disconnect the electrical connection between the second battery (101-2) and the one or more load electrical components (207) based on the control of the first switch (202).
[0311] The voltage of the first battery (101-1) may be lower than the second reference voltage. Based on the voltage of the first battery (101-1), the mode of the electronic device (100) may enter the shipping mode (107). Based on entering the shipping mode (107), the first switching circuit (203-1) may control the second switch (204) to electrically disconnect the third terminal (204-1) and the fourth terminal (204-2). The first switching circuit (203-1) may disconnect the electrical connection between the first battery (101-1) and the one or more load electrical components (207) based on the control of the second switch (204).
[0312] The voltage of the third battery (101-3) may be lower than the second reference voltage. Based on the voltage of the third battery (101-3), the mode of the electronic device (100) may enter the shipping mode (107).
