[0018] FIG. 1 illustrates an example of an electronic device (101) and an external electronic device (160) according to one embodiment. In one embodiment, the electronic device (101) may be a terminal. Referring to FIG. 1, a user terminal (101-1) in the form of a mobile phone (or smartphone) is exemplarily illustrated as an example of the terminal. The form factor of the mobile phone (or smartphone) is not limited to the user terminal (101-1) of FIG. 1, and for example, the electronic device (101) may include a user terminal (101-3) including a deformable flexible display.

[0019] Referring to FIG. 1, according to one embodiment, an electronic device (101) may include at least one of a processor (110), a charging circuit (120), a charging controller (130), and a battery (140). The electronic device (101) may obtain power for driving hardware (e.g., the processor (110)) included in the electronic device (101) from the battery (140). The hardware (or circuit) included in the electronic device (101) for charging the battery (140) may be divided into a charging circuit (120) and / or a charging controller (130).

An example of the structure of a charging circuit (120), a charging controller (130), and a processor (110) disposed within an electronic device (101) to obtain power from an external electronic device (160) connected by a wire through a port (150) is described with reference to FIG. 2.

[0020] Referring to FIG. 1, according to one embodiment, an electronic device (101) may be connected to an external electronic device (160) via a port (150). The port (150) may include a hardware component (e.g., a connector) for supporting wired communication based on a universal serial bus (USB). In the present disclosure, the electronic device (101) may be referred to as a first electronic device. The electronic device (101) may be referred to as a master electronic device in terms of an entity that assigns a unique address (or device identifier) ​​to the external electronic device (160) based on USB. The external electronic device (160) may be referred to as a second electronic device. The external electronic device (160) may be referred to as a slave electronic device in terms of an entity that receives a unique address from a master electronic device of USB.

[0021] According to one embodiment, the electronic device (101) may transmit or receive a power signal based on a USB power delivery (PD) (e.g., USB PD 3.0 standard) protocol while connected to an external electronic device (160) through a port (150). From the perspective of an entity that outputs and / or provides a power signal based on USB PD, the external electronic device (160) may be referred to as a host, a source, and / or a provider. From the perspective of an entity that receives and / or consumes a power signal based on USB PD, the electronic device (101) may be referred to as a client, a sink, and / or a consumer. The embodiment is not limited thereto, and the electronic device (101) may operate as a host of USB PD. In one embodiment supporting the USB PD protocol, a port (150) included in an electronic device (101) may include a USB Type C port (e.g., a USB Type C receptacle and / or a USB Type C plug). In response to a cable (e.g., a USB Type C cable) extending from an external electronic device (160) being connected through the port (150), communication based on the USB PD protocol may be initiated between the electronic device (101) and the external electronic device (160). Operations of the electronic device (101) and the external electronic device (160) communicating with each other based on the USB PD protocol are described with reference to FIGS. 3 to 5. An example of a user interface (UI) displayed by the electronic device (101) that obtains power from the external electronic device (160) based on the USB PD protocol is described with reference to FIG. 6.

[0022] Referring to FIG. 1, an external electronic device (160) electrically connected to an electronic device (101) via a port (150) may include an adapter (160-1) and / or an auxiliary battery (or portable power bank) (160-2). The adapter (160-1) may include a TA (Type-A) adapter. The external electronic device (160) may receive an alternating current (AC) power signal of a distribution system (170) provided from a power plant, and output a direct current (DC) power signal from the AC power signal. The external electronic device (160) may generate a power signal having a voltage and / or current requested by the electronic device (101), and transmit the generated power signal to the electronic device (101). For example, the external electronic device (160) may include a programmable power supply (PPS) that supports regulation of voltage and / or current based on USB PD.

[0023] According to one embodiment, the electronic device (101) may communicate with the external electronic device (160) to adjust the voltage and / or current of a power signal provided from the external electronic device (160) for charging the battery (140). The electronic device (101) may perform a function of adjusting the voltage and / or the current in order to reduce the time it takes for the battery (140) to be charged. The external electronic device (160), which outputs a power signal having a finite range of voltage and / or current, may output a power signal of different power depending on the voltage and / or current. The external electronic device (160) may notify the electronic device (101) that the state of the external electronic device (160) is operating at a power limit based on providing maximum power based on the voltage and / or current requested by the electronic device (101).

[0024] For example, the electronic device (101) may request a power signal having a target current from the external electronic device (160) to charge the battery (140) based on a CC (constant current) charging method. In the example, if the maximum current that can be provided together with the voltage of the power signal is less than the target current, the external electronic device (160) may reach the power limit at the time of outputting the power signal having the maximum current. According to one embodiment, the electronic device (101) may calculate a range of power supported by the external electronic device (160) using information provided from the external electronic device (160) based on identifying the external electronic device (160) that has reached the power limit. Based on the result of calculating the range, the electronic device (101) may change the voltage and / or current requested from the external electronic device (160). Based on the change in voltage and / or current of the power signal by the above request, the electronic device (101) can obtain greater power from the external electronic device (160). Since the electronic device (101) obtains greater power from the external electronic device (160), the electronic device (101) can complete charging of the battery (140) in a shorter time. An example of an electronic device (101) that completes charging of the battery (140) relatively early based on the above example is described with reference to FIG. 7.

[0025] As described above, according to one embodiment, the electronic device (101) can obtain a power signal for fast charging from the external electronic device (160) based on USB PD. For example, the electronic device (101) can maximize the power provided by the external electronic device (160) while charging the battery (140) based on the CC charging method. In order to maximize the power, the electronic device (101) can calculate a range of power outputtable by the external electronic device (160) from a signal (e.g., a PD message) received from the external electronic device (160) based on USB PD. Based on the range, the electronic device (101) can obtain greater power from the external electronic device (160) that has reached its power limit. Based on the power, the electronic device (101) can increase the speed at which the battery (140) is charged.

[0026] Hereinafter, with reference to FIG. 2, exemplary connections of hardware (e.g., a processor (110), a charging circuit (120), a charging controller (130), and / or a battery (140)) included in an electronic device (101) to support USB PD are described.

[0027] FIG. 2 illustrates an example of a block diagram of an electronic device (101) according to one embodiment.

The number of processors (110) may be one or more. For example, the processor (110) may have a multi-core processor structure such as a dual core, a quad core, or a hexa core.

[0029] According to one embodiment, the battery (140) of the electronic device (101) can output electrical energy from chemical energy to be consumed by other circuits and / or hardware components within the electronic device (101). For example, the battery (140) of the electronic device (101) can include a battery cell, a battery module, or a battery pack.

For example, at one end (140-1), when the magnitude of the current input to the battery (140) is greater than the magnitude of the current output from the battery (140), the battery (140) can be charged. When the magnitude of the current output from the battery (140) is greater than the magnitude of the current input to the battery (140), the battery (140) can be discharged. The electronic device (101) can measure the state-of-charge (SOC) and / or open-circuit voltage (OCV) of the battery (140) by using a resistor (240) connected to one end (140-1) of the battery (140) and a gauge circuit (230) connected to both ends (240-1, 240-2) of the resistor (240). In one embodiment, the gauge circuit (230) may be referred to as a fuel gauge.

The port (150) may be used as a downstream facing port (DFP) or an upstream facing port (UFP) depending on the role (e.g., source or sink) of the electronic device (101) based on USB PD. The embodiment is not limited thereto, and the port (150) may be used as a dual role data port (DRD) that supports all of the functions of the DFP and the UFP.

[0032] Referring to FIG. 2, a plurality of pins (terminals) formed in a port (150) based on a USB Type C connector are illustrated. The port (150) may have a structure based on a USB Type C receptacle. Based on the structure of the USB Type C receptacle, an A side and a B side may be formed within the port (150), and 12 pins may be arranged on each of the A side and the B side. Referring to FIG. 2, the 12 pins arranged on the A side may include GND (A1), SSTXp1 (A2), SSTXn1 (A3), VBUS (A4), CC (A5), Dp1 (A6), Dn1 (A7), SBU1 (A8), VBUS (A9), SSRXn2 (A10), SSRXp2 (A11), and GND (A12).

[0033] Referring to FIG. 2, the pins included in the port (150) can be used to receive different electrical signals set by the USB PD. For example, using the CC (configuration channel) (A5, B5) pins, the electronic device (101) can perform an exchange of information based on the USB PD. The information can include a PDO (power data object), which is information transmitted to or received from an external electronic device (e.g., the external electronic device (160) of FIG. 1) that is a PPS. For example, using the Vbus (A4, A9, B4, B9) pins, the electronic device (101) can receive a power signal. The embodiment is not limited thereto, and the electronic device (101) can output a power signal provided from the battery (140) through the Vbus (A4, A9, B4, B9) pins.

[0034] Referring to FIG. 2, each of the pins included in the port (150) may be connected to a circuit dedicated to processing an electrical signal corresponding to the pin. For example, the CC (A5, B5) pins of the port (150) may be connected to one end (130-2) of the charging controller (130). For example, the Vbus (A4, A9, B4, B9) pins of the port (150) may be connected to at least one charging circuit via the OVP IC (210). Referring to FIG. 2, the first charging circuit (221) may be connected to the Vbus (A4, A9, B4, B9) pins of the port (150) via one end (221-2) connected to the OVP IC (210).

In one embodiment, the charge controller (130) can be referred to as a power delivery integrated circuit (PDIC) and / or a configuration channel power delivery (CCPD) IC. The embodiment is not limited thereto, and the electronic device (101) can further include a mux integrated circuit (MUIC) for data communication based on the Dp1 (A6, B6) and Dn1 (A7, B7) pins.

[0036] In one embodiment, the charging controller (130) may be used to relay PPS communication between different hardware of the electronic device (101) (e.g., the processor (110), the first charging circuit (221), and / or the second charging circuit (222)) and an external electronic device. The PPS communication may be performed for adaptive control of power provided from the external electronic device, which is a PPS. The PPS communication may be performed by USB PD. The embodiment is not limited thereto. Referring to FIG. 2, the charging controller (130) may be connected to at least one of the processor (110), the first charging circuit (221), or the second charging circuit (222) through an end (130-1). An interface (e.g., I2C (inter-integrated circuit)) for transmitting and / or receiving digital information may be formed between one end (130-1) of the charging controller (130), one end (110-1) of the processor (110), one end (221-1) of the first charging circuit (221), and one end (222-1) of the second charging circuit (222). Hereinafter, the operation of the hardware included in the electronic device (101) is described in a state in which an external electronic device (e.g., the external electronic device (160) of FIG. 1) for providing power is connected through the port (150).

[0037] Referring to FIG. 2, when a wired connection is established between an electronic device (101) and an external electronic device through a port (150), the charging controller (130) can identify the wired connection based on CC pins (A5, B5) connected through a terminal (130-2).

[0039] According to one embodiment, the first charging circuit (221) may charge the battery (140) based on power received from the processor (110) through the terminal (221-1). For example, the first charging circuit (221) may request the charging controller (130) to transmit a signal through the terminal (221-1) to request a power signal having a voltage and / or current based on the power. Based on a power signal received from an external electronic device through the terminal (221-2), the first charging circuit (221) may apply a voltage and / or current to the terminal (221-3) connected to the battery (140).

[0040] According to one embodiment, the processor (110) of the electronic device (101) can adaptively calculate power obtainable from an external electronic device based on a data signal identified by the charging controller (130). For example, the processor (110) can calculate power to be provided to the first charging circuit (221) from information contained in different data signals provided from the external electronic device (160), such as a fixed PDO (FPDO) and / or an augmented PDO (APDO).

[0041] Hereinafter, with reference to FIG. 3, an operation of calculating power of an external electronic device based on FPDO and / or APDO by a processor (110) of an electronic device (101) according to one embodiment is described.

For example, the operation of the electronic device (101) described with reference to FIG. 3 may be performed by the processor (110) and / or the charging controller (130) of FIG. 1.

[0043] Referring to FIG. 3, in operation (310), the electronic device (101) and the external electronic device (160) may execute a negotiation function related to a power signal. In operation (310), the electronic device (101) may identify the external electronic device (160) connected to a port (e.g., the port (150) of FIGS. 1 and 2) using a charging controller (e.g., the charging controller (130) of FIGS. 1 and 2). In operation (310), the electronic device (101) and the external electronic device (160) may exchange profile information related to power. The profile information may include information on the power demand and / or supply of a device that generated the profile information (e.g., the electronic device (101) and / or the external electronic device (160)). Based on the above profile information, one of the electronic device (101) and the external electronic device (160) can be set as a source of USB PD and the other can be set as a sink of USB PD.

[0044] Referring to FIG. 3, in a state where a negotiation function is executed based on an operation (310), the electronic device (101) may obtain a first data signal (330) from an external electronic device (160) based on a charging controller (e.g., the charging controller (130) of FIGS. 1 and 2). The first data signal (330) may include profile information of the external electronic device (160).

[0045] Referring to FIG. 3, a 32-bit binary code included in a first data signal (330) is illustrated. The bits included in the binary code may have position numbers from 0 to 31. The position numbers may be used to indicate the positions of bits in the binary code. Referring to FIG. 3, ten bits (331) having digits from 0 to 9 may indicate the maximum value of a fixed current supported by an external electronic device (160). Referring to FIG. 3, ten bits (332) having digits from 10 to 19 may indicate a voltage corresponding to the current expressed by the bits (331). For example, an external electronic device (160) that transmits a second data signal (340) may transmit a power signal having a current corresponding to bits (331) of the second data signal (340) and a voltage represented by bits (332) of the second data signal (340). In one embodiment, bits of the first data signal (330), including bits (331, 332), may represent parameters included in Table 1.

[0046] Digit Parameter 31-30 Fixed supply 29 Dual-role power flag 28 USB suspended support flag 27 Unconstrained power flag 26 USB communication capability flag 25 Dual-role data flag 24 Ununchunked extended messages support flag 24 EPR (extended power range) mode capability flag 22 Reserved 21-20 Peak current 19-10 Voltage in units of 50 mV 9-0 Peak current in units of 10 mA

[0047] Referring to Table 1, the electronic device (101) can determine a value obtained by multiplying the number corresponding to the bits (331) of the first data signal (330) by 10 mA as the maximum current of the external electronic device (160) identified by the first data signal (33). The electronic device (101) can determine a value obtained by multiplying the number corresponding to the bits (332) of the first data signal (330) by 50 mV as the maximum voltage of the power signal when the external electronic device (160) provides the power signal having the maximum current. Based on the bits (331, 332) of the first data signal (330), the electronic device (101) can obtain the first power indicated by the first data signal (330). For example, based on the multiplication of voltage and current, the electronic device (101) can obtain the first power by multiplying the maximum current and the maximum value of the voltage.

[0048] Referring to FIG. 3, in operation (320), the electronic device (101) and the external electronic device (160) may execute a function related to a power signal based on the result of executing the negotiation function of operation (310). For example, the electronic device (101) may communicate with the external electronic device (160) based on the first data signal (330) and obtain a power signal from the external electronic device (160). For example, in operation (320), the electronic device (101) may charge the battery of the electronic device (101) (e.g., the battery (140) of FIGS. 1 and 2) based on the power signal obtained from the external electronic device (160).

[0049] According to one embodiment, the electronic device (101) may receive a second data signal (340) from an external electronic device (160) in a state in which a battery of the electronic device (101) is being charged by a charging circuit (e.g., the charging circuit (120) of FIG. 1 and / or the first charging circuit (221) of FIG. 2) that has received a power signal. The state may include a state in which the operation (320) is performed. The state may include a state in which charging based on USB PD is performed. The second data signal (340) may be referred to as a source capability message. The second data signal (340) may include capability information of the external electronic device (160) based on APDO. For example, the second data signal (340) may be transmitted to the electronic device (101) by an external electronic device (160) that supports a power signal of a voltage and / or current that is different from the fixed voltage and / or fixed current of the first data signal (330). Although the second data signal (340) is illustrated as being transmitted in operation (320), the embodiment is not limited thereto. For example, the second data signal (340) may be transmitted from the external electronic device (160) to the electronic device (101) while executing the negotiation function of operation (310). The external electronic device (160) transmitting the second data signal (340) to the electronic device (101) may be performed to indicate a state of the external electronic device (160) at a specific point in time, to indicate a state of the external electronic device (160) based on a power limit, or may be performed repeatedly (or periodically).

[0050] Referring to FIG. 3, a 32-bit binary code included in a second data signal (340) is illustrated. The bits included in the binary code may have digits from 0 to 31. According to one embodiment, the electronic device (101) may identify the maximum current provided by the external electronic device (160) from seven bits (341) having digits from 0 to 6 within the binary code of the second data signal (340). The electronic device (101) may identify the maximum voltage provided by the external electronic device (160) from eight bits (342) having digits from 17 to 24 within the binary code of the second data signal (340). The electronic device (101) can identify the status of the external electronic device related to the power limit from a bit (343) having 27 digits within the binary code included in the second data signal (340). For example, the bit (343) may be referred to as a parameter (or flag) indicating the status. In one embodiment, the bits of the second data signal (340), including bits (341, 342, 343), may represent the parameters included in Table 2.

[0051] Digit Parameter 31~30 APDO Flag 29~28 SPR (standard power range) PPS Supply Flag 27 PPS Power Limit Flag 26~25 Reserved 24~17 Maximum voltage in 100 mV 16 Reserved 15~8 Maximum voltage in 100 mV 7 Reserved 6~0 Maximum current in 50 mA

[0052] Referring to Table 2, the electronic device (101) can determine a value obtained by multiplying the number corresponding to the bits (341) of the second data signal (340) by 50 mA as the maximum current of the external electronic device (160) identified by the second data signal (340). The electronic device (101) can determine a value obtained by multiplying the number corresponding to the bits (342) of the second data signal (340) by 100 mV as the maximum voltage of the external electronic device (160) identified by the second data signal (340). Based on the multiplication of the maximum voltage and the maximum current, the external electronic device (160) can obtain the second power indicated by the second data signal (340).

[0053] According to one embodiment, the electronic device (101) can identify from the second data signal (340) whether the voltage supported by the external electronic device (160) is equal to or greater than a specified voltage (e.g., 9 V). For example, the electronic device (101) can compare the maximum voltage indicated by the bits (342) with the specified voltage. If the maximum voltage is less than the specified voltage, the electronic device (101) can charge the battery using the second charging circuit (222) of FIG. 2. If the maximum voltage is equal to or greater than the specified voltage, the electronic device (101) can charge the battery using the first charging circuit (221) of FIG. 2. At a point in time when the maximum voltage exceeding the specified voltage is identified, the processor of the electronic device (101) (e.g., the processor 110 of FIGS. 1 and 2) may control the first charging circuit (221) of FIG. 2 based on the second power corresponding to the second data signal (340). As the first charging circuit (221) is controlled based on the second power, the electronic device (101) may obtain a power signal approaching the second power or having the second power from the external electronic device (160). The first charging circuit (221) controlled based on the second power may control a charging controller (e.g., the charging controller (130) of FIG. 2) to request a power signal having the second power from the external electronic device. Requesting the power signal having the second power may be performed based on transmission of a data signal including a request data object (RDO), which is information set for requesting a power signal in a USB PD.

[0054] In one embodiment, while charging a battery based on the first charging circuit (221) of FIG. 2, the electronic device (101) may receive a second data signal (340). The electronic device (101) may identify a parameter for indicating a power limit of the external electronic device (160), which is a PPS, at a designated location of a binary code included in the second data signal (340). For example, based on bit (343) of the second data signal (340), the electronic device (101) may identify a state of the external electronic device (160) related to the power limit. When the electronic device (101) identifies a first designated state indicating that the external electronic device (160) has reached its power limit, the electronic device (101) may control the first charging circuit (221) using either the first power corresponding to the first data signal (330) or the second power corresponding to the second data signal (340) (e.g., a relatively low power). When identifying a second designated state (e.g., a state in which the power limit has not been reached) of the external electronic device (160) that is distinct from the first designated state, the electronic device (101) may control the first charging circuit (221) using the first power among the first power or the second power. For example, based on reception of the second data signal (340), the processor of the electronic device (101) may adaptively control the first charging circuit (221).

[0055] Referring to FIG. 3, the transmission of a power signal between the electronic device (101) and the external electronic device (160) based on the operation (320) may be at least temporarily interrupted by a data signal (not shown) of the electronic device (101) and / or the external electronic device (160). For example, the electronic device (101) may transmit a data signal including information (e.g., RDO) in which voltage and / or current are described as 0 to the external electronic device (160). Based on the data signal, the external electronic device (160) may stop transmitting the power signal to the electronic device (101). For example, the electronic device (101) may transmit a data signal including an EOC (end of communication) message to the external electronic device (160). Based on the data signal, the external electronic device (160) may stop transmitting the power signal to the electronic device (101).

[0056] As described above, according to one embodiment, the electronic device (101) can more accurately measure power obtainable from the external electronic device (160) by using data signals transmitted from the external electronic device (160) (e.g., the first data signal (330) and / or the second data signal (340)). Based on the measured power, the electronic device (101) can control a charging circuit (e.g., the first charging circuit (221) of FIG. 2) and / or a charging controller (e.g., the charging controller (130) of FIGS. 1 and 2) of the electronic device (101) to cause the external electronic device (160) to provide the measured power. The electronic device (101) can charge a battery (e.g., the battery (140) of FIGS. 1 and 2) by using the measured power. Since the battery is charged by the measured power, the electronic device (101) can finish charging the battery in a shorter time.

[0057] Hereinafter, with reference to FIG. 4, the operation of the electronic device (101) described above with reference to FIGS. 1 to 3 according to one embodiment is described.

[0058] FIG. 4 illustrates an example of a flowchart of an electronic device according to one embodiment. The electronic device (101) of FIG. 1 may include the electronic device (101) of FIG. 4. The operations of the electronic device (101) described with reference to FIG. 4 may be performed by the processor (110), the charging circuit (120), and / or the charging controller (130) of FIG. 1. At least one of the operations of FIG. 4 may be related to the operations of FIG. 3 (e.g., operation (320) of FIG. 3).

[0059] Referring to FIG. 4, in operation (410), according to one embodiment, an electronic device may obtain power from an external electronic device (e.g., the external electronic device (160) of FIGS. 1 to 3) based on a first data signal received from the external electronic device. The first data signal of operation (410) may include the first data signal (330) of FIG. 3. After executing the negotiation function of operation (310) of FIG. 3, the electronic device may perform operation (410). Using the power of operation (410), the electronic device may charge a battery of the electronic device (e.g., the battery (140) of FIG. 1).

[0060] Referring to FIG. 4, in operation (420), according to one embodiment, an electronic device may receive a second data signal from an external electronic device. The second data signal of operation (420) may include the second data signal (340) of FIG. 3. The electronic device receiving the second data signal based on operation (420) may be performed while acquiring a power signal from the external electronic device based on operation (410).

[0061] Referring to FIG. 4, in operation (430), according to one embodiment, the electronic device can identify whether the maximum voltage of the second data signal is equal to or greater than a specified voltage. The electronic device can identify the maximum voltage supported by the external electronic device from a binary code in the second data signal based on APDO. The specified voltage may be 9 V. The embodiment is not limited thereto. If the maximum voltage is less than the specified voltage (430-No), the electronic device can perform operation (435). If the maximum voltage is equal to or greater than the specified voltage (430-Yes), the electronic device can perform operation (440).

[0062] Referring to FIG. 4, in operation (435), an electronic device according to one embodiment may charge a battery using a second charging circuit. The second charging circuit of operation (435) may include a circuit for charging a battery based on a switching method and / or a CV charging method, such as the second charging circuit (222) of FIG. 2.

[0063] Referring to FIG. 4, in operation (440), according to one embodiment, the electronic device may identify whether the second data signal includes a parameter indicating a first designated state related to a power limit. The parameter of operation (440) may correspond to bit (343) of FIG. 3. The first designated state may be identified by the parameter having a designated value (e.g., binary code 1) indicating that the external electronic device has reached the power limit. If the parameter indicating the first designated state is included in the second data signal (440—Yes), the electronic device may perform operation (450). If the electronic device identifies a parameter indicating a second designated state different from the first designated state (e.g., a parameter having a binary code 0) from the second data signal (440—No), the electronic device may perform operation (445).

[0064] Referring to FIG. 4, in operation (445), according to one embodiment, the electronic device may transmit and / or notify the maximum power of the external electronic device based on the second data signal to the first charging circuit. The first charging circuit of operation (445) may include a circuit for charging a battery based on a DC and / or CC charging method, such as the first charging circuit (221) of FIG. 2. The electronic device may identify the maximum power supported by the external electronic device using the second data signal based on the APDO of operation (420). The electronic device may control the first charging circuit based on the maximum power, such that the first charging circuit charges the battery using a power signal having the maximum power of the external electronic device. For example, if the external electronic device has not reached its power limit, the electronic device may increase the power provided from the external electronic device using the first charging circuit.

[0065] Referring to FIG. 4, in operation (450), according to one embodiment, the electronic device may identify a first power at a maximum voltage of a power signal of an external electronic device based on a first data signal. The electronic device may identify, from the first data signal, a maximum current of the external electronic device based on FPDO and a voltage of the power signal at the maximum current. The electronic device may identify a first power of operation (450) based on a product of the maximum current and the voltage. The first power may represent a maximum power that can be provided by the external electronic device at a fixed voltage and / or fixed current.

[0066] Referring to FIG. 4, in operation 460, according to one embodiment, the electronic device may identify a second power for a power signal of an external electronic device based on a second data signal. The electronic device may identify a maximum voltage and a maximum current of the external electronic device based on APDO from the second data signal. Based on a multiplication of the maximum voltage and maximum current identified from the second data signal, the electronic device may identify the second power. The second power may represent a maximum power in a voltage range and a current range provided by the external electronic device, which is a PPS.

[0067] Referring to FIG. 4, in operation (470), according to one embodiment, the electronic device may transmit either the first power or the second power to the first charging circuit. For example, the electronic device may transmit or notify the first charging circuit of a relatively small amount of power among the first power or the second power.

[0068] Referring to FIG. 4, in operation (480), according to one embodiment, an electronic device may transmit a voltage and / or current to a first charging circuit. The electronic device may identify a charging current and / or voltage (e.g., a float voltage) of a battery based on an SOC of the battery. The electronic device may transmit the identified charging current and / or voltage to the first charging circuit. The charging current and / or the voltage transmitted by the electronic device to the first charging circuit may be less than or equal to a maximum value of a current and / or voltage supported by the first charging circuit.

[0069] Referring to FIG. 4, in operation (490), according to one embodiment, an electronic device may charge a battery based on a first charging circuit. The first charging circuit may determine a voltage range and / or a current range for charging the battery based on the power received by operation (460) and the voltage and current received by operation (470). Based on the voltage range and / or the current range, the first charging circuit may control a charging controller to request a power signal within the voltage range and / or the current range from an external electronic device. The first charging circuit may perform constant current (CC) charging on the battery using the requested power signal.

[0070] In operation (490) of FIG. 4, when a power signal exceeding the voltage range and / or the current range is received, the first charging circuit of the electronic device may operate in a power limit mode. When a power signal within the voltage range and the current range is received, the first charging circuit of the electronic device may operate in a normal mode. In the power limit mode, the first charging circuit may adjust the amount of current input to the battery within the guaranteed current range of the battery. In one embodiment, in the power limit mode, the electronic device may perform operation (480) again to transmit a voltage and / or current based on the SOC to the first charging circuit.

[0071] Referring to FIG. 4, based on the state of the external electronic device indicated by the parameter of operation (440), the electronic device can control the first charging circuit using at least one of the first power indicated by the first data signal or the second power indicated by the second data signal. The electronic device can maximize the power supplied to the battery by the first charging circuit for direct current-based charging according to the first data signal and / or the second data signal.

[0072] According to one embodiment, an electronic device can authenticate an external electronic device that transmitted the second data signal using power measured from an APDO included in the second data signal. Hereinafter, with reference to FIG. 5, an example of the operation of the electronic device for authenticating the external electronic device is described.

[0073] FIG. 5 illustrates an example of a flowchart of an electronic device according to one embodiment. The electronic device (101) of FIG. 1 may include the electronic device of FIG. 5. The operations of the electronic device (101) described with reference to FIG. 5 may be performed by the processor (110), the charging circuit (120), and / or the charging controller (130) of FIG. 1. At least one of the operations of FIG. 5 may be related to at least one of the operations of FIGS. 3 and 4.

[0074] Referring to FIG. 5, in operation (510), according to one embodiment, an electronic device may receive a power signal and a second data signal from an external electronic device (e.g., the external electronic device (160) of FIGS. 1 to 3). The electronic device may perform operation (510) after executing the negotiation function of operation (310) of FIG. 3. The second data signal of operation (510) may include the second data signal (340) of FIG. 3.

[0075] Referring to FIG. 5, in operation (515), according to one embodiment, the electronic device may identify whether the second data signal includes a parameter indicating a first designated state related to a power limit. The electronic device may perform operation (515) of FIG. 5 similarly to operation (440) of FIG. 4. For example, the electronic device may extract a binary code based on APDO from the second data signal and obtain a parameter at a designated position in the binary code (e.g., bit (343) of FIG. 3). If the parameter has a designated value (e.g., binary code 1) indicating the first designated state, the electronic device may determine that the parameter indicating the first designated state is included. If the parameter has another value (e.g., binary code 0) different from the designated value, the electronic device may determine that the parameter indicating another state different from the first designated state is included. In a state where a parameter indicating a first designated state is identified from the second data signal (515-Yes), the electronic device can perform operation (520). In a state where a parameter indicating a second designated state is identified from the second data signal (515-No), the electronic device can perform operation (540).

[0076] Referring to FIG. 5, in operation 520, an electronic device according to an embodiment may request an external electronic device to provide a power signal having a maximum voltage and a voltage that gradually increases. If the external electronic device is identified as operating in a first designated state where the power limit has been reached, the electronic device may perform operation 520. According to an embodiment, the electronic device may identify the maximum voltage of operation 520 based on a maximum current (e.g., a maximum current encoded in bits 341 of FIG. 3) and a maximum voltage (e.g., a maximum voltage encoded in bits 342 of FIG. 3) included in a second data signal. The electronic device may communicate with the external electronic device based on the maximum voltage to obtain a power signal having the maximum voltage. If the power signal has the maximum voltage and a current less than the maximum current, the electronic device may request the external electronic device to increase the voltage and / or current of the power signal. For example, an electronic device may request an external electronic device to increase voltage based on a specified offset voltage (e.g., an offset voltage greater than 20 mV). The request from the electronic device to the external electronic device to increase voltage may be repeated based on a specified number of times.

[0077] Referring to FIG. 5, in operation (525), according to an embodiment, the electronic device may determine whether the current of a power signal provided from an external electronic device increases or is maintained in response to the request of operation (520). Since the electronic device has calculated the maximum voltage and maximum current of the external electronic device based on the second data signal provided from the external electronic device, if the external electronic device operates normally, the external electronic device may transmit a power signal having a current that is increased or maintained (i.e., not decreased) in response to the request. If the current of operation (525) increases or is maintained (525-Yes), the electronic device may perform operation (530). If the current of operation (525) decreases (525-No), the electronic device may perform operation (535). By selectively performing at least one of operations (530, 535), the electronic device may classify the external electronic device as an authenticated charging device or an unauthenticated charging device. An electronic device that has performed a request based on the above-described offset voltage of operation (520) can restore the voltage requested from an external electronic device (e.g., the voltage of the power signal prior to operation (520)) based on performing at least one of operations (530, 535).

[0078] Referring to FIG. 5, in operation (540), according to one embodiment, the electronic device may determine whether the current of the power signal decreases while the voltage of the power signal increases. If it is determined that the external electronic device is operating in a second designated state that has not reached the power limit, the electronic device may perform operation (540). According to one embodiment, the electronic device may request an increase in the voltage of the power signal from the external electronic device based on operations (445, 490) of FIG. 4. If the voltage of the power signal received from the external electronic device increases while the current of the power signal increases or is maintained (540—Yes), the electronic device may perform operation (530). If the voltage of the power signal received from the external electronic device increases while the current of the power signal decreases (540—No), the electronic device may perform operation (535). When the voltage of the power signal received from the external electronic device increases and the current of the power signal decreases (540-No), the electronic device can restore the voltage requested from the external electronic device while performing operation (535).

[0079] Referring to FIG. 5, in operation (530), according to an embodiment, an electronic device may classify an external electronic device into a first category for authenticating a charging device. The first category may be a designated category for classifying an electronic device that is adjustable in power signal according to communication (e.g., PPS communication) between the electronic device and the external electronic device. For example, the first category may be a category for classifying a normal charging device that supports USB PD. While classifying the external electronic device into the first category, the electronic device may perform at least one of the operations of FIGS. 3 and 4 to maintain acquiring a power signal from the external electronic device.

[0080] Referring to FIG. 5, in operation (535), according to one embodiment, the electronic device may classify an external electronic device into a second category. The second category may be a designated category for classifying electronic devices that are unable to change a power signal according to PPS communication. For example, the second category may be a category for classifying abnormal charging devices that do not support USB PD. In a state where the external electronic device is classified into the second category, the electronic device may stop acquiring a power signal from the external electronic device, or may acquire a power signal having a limited voltage and / or current from the external electronic device.

[0081] As described above, according to one embodiment, the electronic device can authenticate the external electronic device by controlling the external electronic device based on the measured power using the second data signal including APDO. Based on authenticating the external electronic device, the electronic device can more reliably obtain a power signal from the external electronic device.

[0082] Below, with reference to FIG. 6, an example of a UI displayed by an electronic device that performs the operations of FIGS. 1 to 5 is described.

[0083] FIG. 6 illustrates an example of a user interface (UI) displayed by an electronic device (e.g., a user terminal (101-1)) according to one embodiment. The electronic device (101) and / or the user terminal (101-1) of FIG. 1 may include the user terminal (101-1) of FIG. 6. The external electronic device (160) and / or the adapter (160-1) of FIG. 1 may include the adapter (160-1) of FIG. 6. The operation of the user terminal (101-1) described with reference to FIG. 6 may be performed by the electronic device (101) and / or the processor (110) of FIG. 1.

[0084] According to one embodiment, a user terminal (101-1) may include a display (605) as a means for visually outputting information. An adapter (160-1) connected to a power distribution system (170) may be connected to the user terminal (101-1) via a port (150). Referring to FIG. 6, based on the connection of a connector (610) (e.g., a USB Type-C plug) extended from the adapter (160-1) and a port (150) (e.g., a USB Type-C receptacle), the user terminal (101-1) may perform an operation (e.g., operation (310) of FIG. 3) described above with reference to FIGS. 1 to 5 to execute a negotiation function for USB PD with the adapter (160-1). After executing the negotiation function, in response to receiving a power signal based on the negotiation function, the user terminal (101-1) may display a screen as illustrated in FIG. 6 on the display (605). Hereinafter, a screen may refer to a user interface (UI) displayed within at least a portion of a display. A screen may include, for example, an activity of the Android operating system.

[0085] Referring to FIG. 6, according to one embodiment, the user terminal (101-1) may display a visual object related to the power signal on the display (605) while receiving the power signal through the adapter (160-1). For example, the user terminal (101-1) may guide charging of a battery (e.g., battery (140) of FIGS. 1 and 2) based on the power signal by using a visual object such as text (620) included in a lock screen. The lock screen may be displayed to restrictively execute a designated function, including an authentication function, among the functions supported by the user terminal (101-1) in an always on display (AOD) state and / or a locked state of the user terminal (101-1).

[0086] For example, the user terminal (101-1) may display a visual object related to the power signal within an area provided by the system application of the user terminal (101-1), such as a notification panel (630). For example, the user terminal (101-1) may display a visual object in the form of a button (640) for guiding charging of a battery based on the power signal.

[0087] In one embodiment, using text (620) and / or button (640), the user terminal (101-1) may indicate a status of acquiring a power signal from an external electronic device based on the operations described above with reference to FIGS. 1 to 5. For example, while charging a battery based on operation (435) of FIG. 4, the user terminal (101-1) may display designated text (e.g., “slow charge” and / or “normal charge”) on text (620) and / or button (650) to guide that the battery is being charged at a low or normal speed. For example, while charging a battery based on operation (490) of FIG. 4, the user terminal (101-1) may display designated text (e.g., “fast charge” and / or “ultra-fast charge”) on text (620) and / or button (650) to guide that the battery is being charged at a high speed. For example, the user terminal (101-1) may display text (620) including “Ultra-fast charging” while acquiring a power signal having a power exceeding 24.5 W. For example, the user terminal (101-1) may display text (620) including “Ultra-fast charging 2.0” while acquiring a power signal having a power exceeding 43 W.

[0088] In one embodiment, the user terminal (101-1) may display the result of authenticating the external electronic device on the display (605) based on the operation of FIG. 5. For example, if an abnormal external electronic device is identified based on the operation (535) of FIG. 5, the user terminal (101-1) may display a designated text (e.g., “An unauthenticated device is connected”) on the text (620) and / or button (650) to guide that the external electronic device is being charged.

[0089] Hereinafter, with reference to FIG. 7, the charging speed of a user terminal (101-1) that measures power supported by an external electronic device using APDO and FPDO is described based on an exemplary graph.

[0090] FIG. 7 illustrates an example of a graph (700) of a current of a power signal received by an electronic device, according to one embodiment. The electronic device (101) of FIG. 1 may include the electronic device of FIG. 7. Referring to FIG. 7, a graph (700) is illustrated that includes an input current (710) of a battery while the electronic device (101) is charging a battery, according to one embodiment. The horizontal axis of the graph (700) may represent time, and the vertical axis may represent current (unit: ampere (A)). The input current (720) of the graph (700) may represent a current that another electronic device, different from the electronic device (101), inputs to the battery for charging the battery, according to one embodiment. The graph (700) of FIG. 7 is exemplary, and the embodiment is not limited thereto.

[0091] Referring to the input current (710) of FIG. 7, while charging the battery with a fixed current of 4.6 A, the electronic device (101) can maintain the current of the power signal at the fixed current based on the first charging circuit (221) of FIG. 2. The electronic device (101) can charge the battery based on the fixed current of 4.6 A until time t1. Until time t1, the electronic device (101) can identify the power (e.g., the multiplication of voltage and current included in APDO) supported by the external electronic device based on a data signal (e.g., the second data signal (340) of FIG. 3) transmitted from the external electronic device (e.g., the external electronic device (160) of FIGS. 1 and 2), and request a power signal having the identified power. Based on the request, the electronic device (101) can obtain a power signal having a current close to the fixed current until time t1.

[0092] Referring to the input current (720) of FIG. 7, while charging the battery with a fixed current of 4.6 A, the input current (720) may gradually decrease from 4.6 A. At time t2 when charging the battery with the fixed current is completed, the input current (720) may decrease by 180 mA to 4.42 A. In one embodiment, since the electronic device (101) more accurately measures the power provided from the external electronic device using the FPDO and / or APDO included in the data signal of the external electronic device and communicates with the external electronic device based on the measured power, the input current (710) of the electronic device (101) may be greater than the input current (720) by a difference (730). Referring to FIG. 7, it can be seen that the length of the time interval for charging the battery with the fixed current is reduced as the electronic device (101) receives the input current (710) that is maintained at 4.6 A. For example, the electronic device (101) may complete charging of the battery earlier than other electronic devices.

[0093] According to one embodiment, the electronic device can obtain power signals of power and voltage of Table 3 for external electronic devices providing the maximum power and current of Table 3.

[0094] Maximum power and current of external electronic devices Power provided to the electronic device (W) Maximum voltage applied to the battery (V) 165W + 5A 5 11.956 265W + 3A 3 11345W + 5A 4 59.78 2445W + 3A 3 11525W + 3A 2 4.93 9.065

[0095] Referring to Table 3, according to one embodiment, an electronic device can optimize the power and / or voltage provided from an external electronic device based on the operations described with reference to FIGS. 1 to 6. Based on the optimized power and / or voltage, the electronic device can terminate battery charging in a shorter time. For example, the electronic device can obtain a power signal having a fixed current set by a CC charging method based on a voltage different from a fixed voltage. Since the power signal having a voltage different from the fixed voltage is provided, the external electronic device can provide power exceeding the power range that can be provided based on the fixed voltage.

[0096] As described above, according to one embodiment, the electronic device can measure the power range of an external electronic device for providing a power signal based on information (e.g., FPDO and / or APDO) included in a data signal provided from the external electronic device. The electronic device can then change the power provided from the external electronic device based on the measured power range. For example, even if the external electronic device has reached its power limit, the electronic device can increase the power provided from the external electronic device based on the power range.

[0097] Hereinafter, with reference to FIG. 8, one or more hardwares and / or one or more programs included in the electronic devices of FIGS. 1 to 7 are described.

The communication module (890) may operate independently from the processor (820) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (890) may include a wireless communication module (892) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (894) (e.g., a local area network (LAN) communication module, or a power line communication module). Any of these communication modules may communicate with an external electronic device (804) via a first network (898) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (899) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules may be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (892) may use subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (896) to verify or authenticate the electronic device (801) within a communication network such as the first network (898) or the second network (899).

[0118] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).

[0119] According to one embodiment, commands or data may be transmitted or received between the electronic device (801) and an external electronic device (804) via a server (808) connected to a second network (899). Each of the external electronic devices (802 or 804) may be the same or a different type of device as the electronic device (801). According to one embodiment, all or part of the operations executed in the electronic device (801) may be executed in one or more of the external electronic devices (802, 804, or 808). For example, when the electronic device (801) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (801) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least a part of the service.

According to various embodiments, the operations performed by a module, program, or other component may be executed sequentially, in parallel, iteratively, or heuristically, or one or more of the operations may be executed in a different order, omitted, or one or more other operations may be added.

[0126] In one embodiment, a method may be required to optimize and / or maximize power obtained from an external electronic device by using information provided from the external electronic device based on USB PD (e.g., FPDO and / or APDO provided via CC pins). As described above, according to one embodiment, an electronic device (e.g., electronic device (101) of FIG. 1) may include a port (e.g., port (150) of FIG. 1), a battery (e.g., battery (140) of FIG. 1), a charging circuit (e.g., charging circuit (120) of FIG. 1), a charging controller (e.g., charging controller (130) of FIG. 1), and a processor (e.g., processor (110) of FIG. 1). The processor may be configured to identify a first data signal (e.g., first data signal (330) of FIG. 3) received via the port using the charging controller. The processor may be configured to, based on the first data signal, communicate with an external electronic device (e.g., the external electronic device (160) of FIG. 1) connected to the port and obtain a power signal from the external electronic device. The processor may be configured to receive a second data signal (e.g., the second data signal (340) of FIG. 3) from the external electronic device, while the battery is being charged by the charging circuit that has received the power signal. The processor may be configured to control the charging circuit based on at least one of the first power indicated by the first data signal or the second power indicated by the second data signal, based on a parameter included in the second data signal and indicating a state of the external electronic device related to a power limit. In one embodiment, the electronic device may control the charging circuit based on the power of the external electronic device identified by the data signal provided from the external electronic device, thereby maximizing or optimizing the power obtained from the external electronic device.

[0127] For example, the processor may be configured to identify, at a designated location in the binary code included in the second data signal, the parameter for indicating the power limit of the external electronic device, which is a programmable power supply.

[0128] For example, the processor may be configured to obtain, from the second data signal, the binary code based on an augmented power data object (APDO) representing the state of the external electronic device at a moment.

[0129] For example, the processor may be configured to identify the first power based on a voltage and a maximum current included in a binary code included in the first data signal.

[0130] For example, the processor may be configured to obtain the binary code based on a fixed power data object (FPDO) including capability information of the external electronic device from the first data signal.

[0131] For example, the processor may be configured to identify the second power based on a maximum voltage and a maximum current included in a binary code included in the second data signal.

[0132] For example, the processor may be configured to transmit to the charging circuit a lesser of the first power or the second power based on identifying the parameter having a designated value indicative of the power limit.

[0133] For example, the processor may be configured to control the charging circuit based on at least one of the first power or the second power, based on identifying a maximum voltage of the external electronic device that exceeds a specified voltage from the second data signal.

[0134] For example, the processor may be configured to control charging of the battery based on the power signal using a second charging circuit (e.g., the second charging circuit (222) of FIG. 2) that is different from the first charging circuit (e.g., the first charging circuit (221) of FIG. 2) based on identifying the maximum voltage below the designated voltage from the second data signal.

[0135] For example, the first charging circuit may include a circuit for charging the battery based on direct current. The second charging circuit may be configured to include a circuit for charging the battery based on a variable voltage.

[0136] For example, the processor may be configured to request the external electronic device to increase the current of the power signal using the charge controller based on identifying the parameter having a designated value indicative of the power limit.
