Description

Electronic device comprising multiple batteries and method of operating the same

[0001] Various embodiments of this document relate to an electronic device including a plurality of batteries and a method of operating the same.

[0002] The use of portable electronic devices such as smartphones, tablet PCs, wearable devices, and augmented reality (AR) glasses has been on the rise recently. This rapid increase in electronic device usage has led to active research into batteries that can extend their operating time. These electronic devices can be configured to utilize multiple batteries to provide more power and stability.

[0003] An electronic device according to one embodiment may include a first battery (381), a second battery (382) for providing power to a system, a flexible printed circuit board (FPCB) connecting the first battery and the second battery, a first charging circuit (320) for providing power to the first battery and the second battery or providing power to the system, a main wiring (341) disposed on the flexible printed circuit board, connected to the first charging circuit, and passing through the flexible printed circuit board, a connection wiring (342) connecting the system and the second battery and connected to the main wiring, one or more processors (390), and a memory. The memory may store instructions that, when executed by the one or more processors, control the first charging circuit to provide power to the system via the main wiring and the connection wiring, and control the first charging circuit to provide power to the second battery via the main wiring and the connection wiring.

[0004] An electronic device according to one embodiment may include a first battery, a second battery for providing power to a system, a flexible printed circuit board connecting the first battery and the second battery, a first charging circuit for providing power to the first battery and the second battery or to the system, a main wiring disposed on the flexible printed circuit board, connected to the first charging circuit, and passing through the flexible printed circuit board, a connection wiring connecting the system and the second battery and connected to the main wiring, one or more processors, and a memory. The memory may store instructions that, when executed by the one or more processors, control the first charging circuit to provide power to the second battery through the main wiring and the connection wiring, and cause the second battery to provide power to the system through the connection wiring.

[0005] An electronic device according to one embodiment may include a first battery, a second battery for providing power to a system, a flexible printed circuit board connecting the first battery and the second battery, a first charging circuit for providing power to the first battery and the second battery or to the system, a main wiring disposed on the flexible printed circuit board, connected to the first charging circuit, and passing through the flexible printed circuit board, a connection wiring connecting the system and the second battery and connected to the main wiring, at least one processor, a first housing accommodating the first battery and the first charging circuit, a second housing accommodating the second battery and the system, a hinge unit connecting the first housing and the second housing, and a memory. The memory may store instructions that, when executed by the one or more processors, control the first charging circuit to provide power to the system via the main wiring and the connection wiring.

[0006] In one embodiment, the electronic device includes a charging circuit that provides power to the system. The charging circuit can provide power to the battery or the system. The path through which power is provided from the charging circuit to the second battery and the path through which power is provided from the charging circuit to the system can share a main path passing through a hinge portion of a flexible printed circuit board. The hinge portion of the flexible printed circuit board can refer to a portion that deforms when the electronic device is folded. Furthermore, the second battery can directly provide power to the system through wiring that does not pass through the hinge portion of the flexible printed circuit board. According to such a structure, the discharge efficiency of the second battery can be improved.

[0007] Since the path for power supplied from the charging circuit to the secondary battery and the path for power supplied from the charging circuit to the system share the main path passing through the hinge portion of the flexible printed circuit board, the number of wires can be reduced. As the number of wires is reduced, free space can be created on the flexible printed circuit board. The space occupied by the main wire or ground wire on the flexible printed circuit board can be expanded, which can reduce resistance. By providing a slit in the free space of the flexible printed circuit board, the convenience and workability of assembly can be improved when assembling the flexible printed circuit board to the housing.

[0008] The effects of the wearable electronic device according to various embodiments are not limited to those mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description below.

In some embodiments, two or more lenses (infrared camera, wide-angle and telephoto lenses) and image sensors may be arranged on one side of the electronic device (201).

[0068] In one embodiment, referring to FIG. 2b, the hinge housing (230a) may be configured to be disposed between the first housing portion (210) and the second housing portion (220) so as to cover an internal component (e.g., the hinge unit (230)). According to one embodiment, the hinge unit (230) may be covered by a portion of the first housing portion (210) and the second housing portion (220) or exposed to the outside, depending on the state of the electronic device (201) (unfolded state, intermediate state, or folded state).

[0069] In one embodiment, as illustrated in FIG. 2A, when the electronic device (201) is in an unfolded state (e.g., a fully unfolded state), the hinge unit (230) may be substantially covered by the first housing portion (210) and the second housing portion (220) and not exposed.

[0070] In one embodiment, as illustrated in FIG. 2b, when the electronic device (201) is in a folded state (e.g., a fully folded state), the hinge unit (230) may be exposed externally between the first housing portion (210) and the second housing portion (220).

[0071] In one embodiment, when the first housing portion (210) and the second housing portion (220) are in an intermediate state (folded with a certain angle), the hinge unit (230) may be partially exposed to the outside between the first housing portion (210) and the second housing portion (220). However, in this case, the exposed area may be less than that in the completely folded state. In one embodiment, the hinge unit (230) may include a curved surface.

[0072] In one embodiment, the first side region (241) and the second side region (242) may be formed to surround at least a portion of the border region of the display (250). For example, the first side region (241) and the second side region (242) may surround the front and / or side of the border region of the display (250). In one embodiment, the first side region (241) and the second side region (242) may be formed to surround at least a portion of the border region of the display (250).

[0073] In one embodiment, the display (250) may be disposed on a space formed by the housing structures (210, 220). For example, the display (250) may be seated on a recess formed by the housing structures (210, 220) and may be visible from the outside through the front of the electronic device (201). For example, the display (250) may form a majority of the front of the electronic device (201). For example, the front of the electronic device (201) may include the display (250) and a portion of the first housing portion (210) adjacent to the display (250) and a portion of the second housing portion (220). For example, the back of the electronic device (201) may include a first back cover (215), a portion of a first housing portion (210) adjacent to the first back cover (215), a second back cover (225), and a portion of a second housing portion (220) adjacent to the second back cover (225).

[0074] In one embodiment, the display (250) may refer to a display in which at least a portion of the display can be transformed into a flat or curved surface. According to one embodiment, the display (250) may include a folding area (253), a first area (251) arranged on one side (e.g., the left side of the folding area (253) illustrated in FIG. 2A) with respect to the folding area (253), and a second area (252) arranged on the other side (e.g., the right side of the folding area (253) illustrated in FIG. 2A). However, the division of areas of the display (250) illustrated in FIG. 2A is exemplary, and the display (250) may be divided into a plurality of areas (e.g., four or more or two) depending on the structure or function. For example, in the embodiment illustrated in FIG. 2A, the regions of the display (250) may be divided by a folding region (253) extending parallel to the folding axis (A), but in one embodiment, the regions may also be divided based on another folding axis of the display (250) (e.g., a folding axis parallel to the width direction of the electronic device).

[0075] In one embodiment, the display (250) may be coupled with or disposed adjacent to a touch panel having a touch detection circuit and a pressure sensor capable of measuring the intensity (pressure) of a touch. For example, the display (250) may be coupled with or disposed adjacent to a touch panel that detects an electromagnetic resonance (EMR) stylus pen, as an example of a touch panel.

[0076] In one embodiment, the first region (251) and the second region (252) may have an overall symmetrical shape centered on the folding region (253). However, unlike the first region (251), the second region (252) may include a cut notch depending on the presence of the sensor region (222), but may have a shape symmetrical with respect to the first region (251) in other regions. For example, the first region (251) and the second region (252) may include a portion having a symmetrical shape and a portion having an asymmetrical shape.

[0077] In one embodiment, the edge thicknesses of the first region (251) and the second region (252) may be formed differently from the edge thickness of the folding region (253). The edge thickness of the folding region (253) may be formed thinner than the thicknesses of the first region (251) and the second region (252). In terms of thickness, the first region (251) and the second region (252) may have an asymmetrical shape when the first region (251) and the second region (252) are viewed in cross-section.

[0078] For example, the edge of the first region (251) may be formed to have a first radius of curvature, and the edge of the second region (252) may be formed to have a second radius of curvature that is different from the first radius of curvature. In one embodiment, in terms of thickness, the first region (251) and the second region (252) may have a symmetrical shape when the first region (251) and the second region (252) are viewed in cross-section.

[0079] Hereinafter, the operation of the first housing part (210) and the second housing part (220) and each area of ​​the display (250) according to the state of the electronic device (201) (e.g., folded state, unfolded state, or intermediate state) will be described.

[0080] In one embodiment, when the electronic device (201) is in an unfolded state (e.g., FIG. 2a), the first surface (210a) of the first housing portion (210) and the third surface (220a) of the second housing portion (220) may be arranged to face the same direction at an angle of about 180 degrees. The surface of the first region (251) and the surface of the second region (252) of the display (250) may form an angle of 180 degrees with each other and face the same direction (e.g., toward the front of the electronic device). The folding region (253) may form the same plane as the first region (251) and the second region (252).

[0081] In one embodiment, when the electronic device (201) is in a folded state (e.g., FIG. 2b), the first surface (210a) of the first housing portion (210) and the third surface (220a) of the second housing portion (220) may be arranged to face each other. The surface of the first region (251) and the surface of the second region (252) of the display (250) may form a narrow angle (e.g., between 0 and 10 degrees) with each other and may face each other. The folding region (253) may be variable to a curved surface having at least a portion of a predetermined curvature.

[0082] In one embodiment, when the electronic device (201) is in an intermediate state, the first housing portion (210) and the second housing portion (220) may be arranged at a certain angle with respect to each other. The surface of the first region (251) and the surface of the second region (252) of the display (250) may form an angle that is greater than an angle in a folded state and less than an angle in an unfolded state. The folding region (253) may be variable to a curved surface having at least a portion of a certain curvature, and the curvature at this time may be less than that in a folded state.

[0083] FIG. 3 is a block diagram schematically illustrating a configuration of an electronic device including a plurality of batteries connected in parallel by a flexible printed circuit board (FPCB) according to one embodiment.

[0084] Referring to FIG. 3, the electronic device (301) may include an OVP (310), a first system (311), a second system (312), a processor (390), a first charging circuit (320), a second charging circuit (330), a first battery (381), a second battery (382), a first limiter (384), and a second limiter (385). For example, the processor (390), the first battery (381), the second battery (382), the first limiter (384), and the second limiter (385) may be implemented substantially identically to the processor (390), the first battery (381), the second battery (382), the first limiter (384), and the second limiter (385) described in FIG. 2. The electronic device (301) according to one embodiment is not limited thereto and may be formed by further including various components or excluding some of the components. The electronic device (301) according to one embodiment may further include all or part of the electronic device (101) illustrated in FIG. 1.

[0085] In one embodiment, the OVP (310, over voltage protector) may perform a function of protecting the first charging circuit (320) and / or the second charging circuit (330) from power provided from an external power source (305). The external power source (305) may be an external power transmitter (e.g., a travel adapter (TA)). For example, the OVP (310) may perform an over voltage protection function. For example, the OVP (310) may block power having a voltage greater than a specified voltage.

[0086] According to one embodiment, the first charging circuit (310) may convert power provided from an external power transmitter (305) and provide the converted power to the first system (311) and the second system (312). The first charging circuit (310) may convert power provided from the first battery (381) and provide the converted power to the first system (311). Power provided from the second battery (382) may be provided directly to the second system (312) without passing through the first charging circuit (310).

[0087] The first charging circuit (310) can convert power into a form required by the first system (311) and the second system (312). For example, the first charging circuit (310) can be implemented as a PMIC (Power Management Integrated Circuit). For example, the first system (311) and the second system (312) can refer to components of the electronic device (301). For example, the first system (311) can refer to components of the electronic device included in the first housing. The second system (312) can refer to components of the electronic device (301) included in the second housing. For example, the first system (311) and the second system (312) can be implemented substantially the same as the system (290) of FIG. 2. According to one embodiment, at least some of the functions of the first charging circuit (320) can be performed by the processor (390).

[0088] According to one embodiment, the electronic device (301) may be implemented as a foldable electronic device including a flexible display. The electronic device (301) may be folded or unfolded by a hinge. The electronic device (301) may include a first housing and a second housing that are connected to each other by a hinge. According to one embodiment, a first battery (381) and a first system (311) may be disposed in the first housing, and a second battery (382) and a second system (312) may be disposed in the second housing. The first battery (381) and the first system (311) may be connected to the second battery (382) and the second system (312) through a flexible printed circuit board (FPCB). For example, a second path that provides power from the charging circuit (380) to the second battery (382) may include a resistance (R) by the FPCB.

[0089] According to one embodiment, the first limiter (384) may be located inside the first charging circuit (320). It should be noted that the location of the first limiter (384) is not limited thereto.

[0090] According to one embodiment, the electronic device (301) can provide power provided from the second battery (382) directly to the second system (312) without passing through the first charging circuit (310). If the power provided from the second battery (28) passes through the first charging circuit (320), additional wiring passing through a flexible printed circuit board (FPCB) must be provided. In this case, discharge loss may occur. However, in one embodiment, since the power provided from the second battery (382) does not have to pass through the first charging circuit (320) arranged in the first housing, the loss due to the resistance (R) of the FPCB is reduced, and thus the discharge loss can be reduced.

[0091] According to one embodiment, the wiring of the path that provides power from the first charging circuit (320) to the second system (312) and the wiring of the path that provides power from the first charging circuit (320) to the second battery (382) may be shared on a flexible printed circuit board (FPCB).

[0092] According to one embodiment, the first charging circuit (320) may receive power from an external power transmitter (305) via the OVP (310).

The first charging circuit (320) may include a circuit for providing power to the first battery (381) and a circuit for providing power to the second battery (382). For example, the circuit for providing power to the first battery (281) and the circuit for providing power to the second battery (382) may include a direct charger circuit (e.g., a switched capacitor circuit). For example, the circuit for providing power to the first battery (381) and the circuit for providing power to the second battery (382) may be different types of circuits.

[0093] According to one embodiment, the processor (390) (e.g., application processor (AP)) can control the overall operation of the electronic device (301). For example, the processor (390) can be implemented in the same or similar manner as the processor (120) of FIG. 1. The processor (390) can check the first voltage to be applied to the first battery (381). The processor (390) can request power from an external power source (305) (e.g., a power transmitter) based on the first voltage to be applied to the first battery (381) or the second battery (382). Through this, the electronic device (301) can determine the magnitude of the voltage to be applied to the first charging circuit (320) based on the first voltage to be applied to the first battery (381) or the second battery (382). One or more processors (390) can be provided.

[0094] According to one embodiment, each of the first battery (381) and the second battery (382) may be connected to ground wires (348, 349). For example, the ground wires (348, 349) may include a first ground wire (348) for connecting the first battery (381) to ground, and a second ground wire (349) for connecting the second battery (382) to ground. For example, the first ground wire (348) and the second ground wire (349) may be arranged on a flexible printed circuit board (FPCB). Although the first ground wire (348) and the second ground wire (349) are illustrated as separate wires, it should be noted that they may be a single integrated wire that is simultaneously connected to the first battery (381) and the second battery (382).

[0095] According to one embodiment, the first charging circuit (320) can provide power to the second battery (382) through a first path. For example, the first path can include a main wire (341) arranged on a flexible printed circuit board (FPCB) and a connection wire (342) connected to the main wire (341). The connection wire (342) can be a wire that connects the second battery (382) and the second system (312). A second limiter (385) can be arranged on the connection wire (342). The first charging circuit (320) can provide power to the second battery (382) through the main wire (341) and the connection wire (342).

[0096] In one embodiment, the first charging circuit (320) may provide power to the first battery (381) via a second path. For example, the second path may include a charging wire (343) connecting the first charging circuit (320) and the first battery (381). The system wire (344) may connect the first system (311) and the main wire (341).

[0097] According to one embodiment, the magnitude of the voltage output by the first charging circuit (320) to provide power to the second battery (382) and the magnitude of the voltage output by the first charging circuit (320) to provide power to the second system (312) may be the same.

[0098] According to one embodiment, the second charging circuit (330) may have its output connected to the system wiring (344).

[0099] According to one embodiment, the second charging circuit (330) may be provided for fast charging. For example, in the normal charging mode, the processor (390) may control the first charging circuit (320) so that power is supplied from the first charging circuit (320) to the first battery (381) and the second battery (382). For example, in the fast charging mode, the processor (390) may control the second charging circuit (330) so that power is supplied from the second charging circuit (330) to the first battery (381) and the second battery (382). For example, the fast charging may be a programmable power supply (PPS) method.

[0100] According to one embodiment, the electronic device (301) may further include a memory (e.g., memory (130) of FIG. 1). The memory may store instructions. For example, one or more memories may be provided. Instructions may be stored in a single memory, or a combination of multiple memories may store instructions. The instructions stored in the memory may be executed by one or more processors (390). When executed by the processor (390), the memory may include instructions for controlling the first charging circuit (320) to provide power to the system through the main wire (341) and the connection wire (342), and for controlling the first charging circuit (320) to provide power to the second battery (382) through the main wire (341) and the connection wire (342).

[0101] According to one embodiment, the input voltage of the second limiter (385) may be the same as the input voltage of the second system (312). The power of the second battery (382) may be supplied directly to the second system (312) through the connection wiring (342) without passing through the flexible printed circuit board (FPCB).

[0105] First, referring to FIG. 4, in the normal charging mode, the processor (390) can control the first charging circuit (320) to provide power to the first battery (381) and the second battery (382). The processor (390) can request power from the external power source (305) based on the voltages required by the first battery (381) and the second battery (382). The power provided from the external power source (305) can be transferred to the first charging circuit (320) via the OVP (310). The first charging circuit (320) can provide power to the second battery (382) through a first path. For example, the first path can include a main wire (341) and a connection wire (342). A second limiter (385) can be arranged on the connection wire (342). The first charging circuit (320) can provide power to the first battery (381) through a second path. For example, the second path can include a charging wire (343).

[0106] Next, referring to FIG. 5, in the fast charging mode, the processor (390) can control the second charging circuit (330) to provide power to the first battery (381) and the second battery (382). The processor (390) can request power from the external power source (305) based on the voltage required by the first battery (381) and the second battery (382). The power provided from the external power source (305) can be transferred to the second charging circuit (330) via the OVP (310). The output terminal of the second charging circuit (330) can be connected to the main wiring (341). The power transferred to the main wiring (341) can be transferred to the first charging circuit (320) and at the same time, can be transferred to the connection wiring (342) through the flexible printed circuit board (FPCB). Power transmitted through the connection wire (342) can be provided to the second battery (382). Power transmitted to the first charging circuit (320) can be provided to the first battery (381).

[0107] The processor (390) can control the power flow direction of the main wiring (341) and the first charging circuit (320) depending on which charging mode is used, either the normal charging mode or the fast charging mode. For example, in the normal charging mode, the processor (390) can control the first charging circuit (320) so that power flows from the first charging circuit (320) toward the main wiring (341). In the normal charging mode, the processor (390) can control the first charging circuit (320) so that power flows from the main wiring (341) toward the first charging circuit (320).

[0108] In one embodiment, referring to FIG. 6, in a discharged state, power provided from the first battery (381) may be transmitted to the first system (311) via the charging wire (343), the first charging circuit (320), the main wire (341), and the system wire (344).
