Description

Technical Field

[0001] Various embodiments of this disclosure relate to electronic devices and methods including flexible displays. Background Technology

[0002] Recently, technologies related to flexible displays that can be bent by externally applied forces have been actively developed. Flexible displays can be temporarily bent or remain bent by applied forces, allowing users to view the screen displayed on the display in different areas according to their preferences.

[0003] Users can manipulate the display to a desired form and use the manipulated display. Specifically, the flexible display may also include a touch panel, and the user can provide input to the display manipulated to the desired form. The display according to the embodiments provides the same input interface despite the change in the form of the flexible display. Therefore, when the form of the flexible display changes, the user may have difficulty providing input.

[0004] Flexible or rollable electronic devices using flexible displays can utilize drive motors to automatically operate the expansion / contraction of the flexible display. Recently, high power consumption has become unavoidable because the thrust of the drive motor must exceed the sum of the repulsive force, mechanical sliding friction, and the reverse driving force of the motor used to roll or slide the flexible display. Therefore, high-power motors are being used for the expansion / contraction of flexible displays in electronic devices. Summary of the Invention

The multiple switches included in the switching circuit 330 can be, for example, knife switches of SPST or SPDT, or MOSFET switches, but this disclosure is not limited thereto. Turning off a switch is an indication of electrical disconnection and can mean an open or disconnected state, while turning on a switch is an indication of electrical connection and can mean an on, closed, or short-circuited state.

In this case, the user can, for example, set the multiple batteries to operate in a always series connection state during motor drive via a user settings screen.

[0079] When it is recognized that a consistently high-voltage drive for the motor is required, at least one processor 120 according to the embodiment can control the flexible display 261 to display a drive battery setting screen to change to a consistently high-voltage state. When at least one processor 120 receives a selection input for an object included in the battery setting screen for selecting motor drive voltage performance, at least one processor 120 can control the flexible display 261 to display an extended screen (e.g., a toggled screen or a pop-up screen) from the battery setting screen, and when a selection input for a second object (e.g., manual (always high voltage)) included in the extended screen is received, it can change to a consistently high-voltage state, such that the motor 321 is always driven at a high voltage. Here, the motor drive voltage performance selection is a user-understood representation and can actually be replaced by selecting a motor drive voltage type or selecting the electrical connection state of multiple batteries powering the motor drive from parallel and series connections.

[0080] When at least one processor 120 according to an embodiment receives a selection input for a first object (e.g., automatic) included in the extended screen, the at least one processor 120 can automatically determine the optimal drive voltage and drive the motor 321 based on conditions such as remaining battery capacity (e.g., battery voltage) and / or based on low-temperature operation settings.

The electronic device can recognize that the drive voltage used to drive the motor is to operate at a second voltage (e.g., about 4V to 8V or less) that is higher than the reference voltage, and connects multiple batteries in series to the boost circuit via a switching circuit, so that the boost circuit applies the power of the second voltage to the motor.

[0116] In operation 811, the electronic device can apply the battery voltage as an input voltage to the boost circuit according to the set connection state (e.g., parallel connection state) or the changed connection state (e.g., the first state of series connection state), and use the power (e.g., about 10W) ​​of the voltage output from the boost circuit (e.g., the voltage boosted from the input voltage) to drive the motor.

[0117] In operation 813, according to the embodiment, the electronic device can identify whether the motor drive is complete. As a result of the identification, if the motor drive is complete, the electronic device can execute operation 815; otherwise, operation 811 can be executed again.

[0118] In operation 815 (operation 813 - Yes), according to an embodiment, when the motor drive is complete, the electronic device can change or maintain the electrical connection state of the multiple batteries in a parallel connection state (e.g., a second state) via a switching operation of the switching circuit. According to an embodiment, if a change in the parallel connection state is identified in operation 807, and the motor is driven in a series connection state in operations 809 and 811, then in operation 715, the electronic device can switch (e.g., change or restore) from the series connection state (e.g., a first state) to the parallel connection state (e.g., a second state) and connect the multiple batteries in parallel to the boost circuit. According to an embodiment, if a parallel connection state is identified in operation 807, and the motor is driven in a parallel connection state in operation 811, then in operation 815, the electronic device can maintain the parallel connection state as is.

[0119] According to an embodiment, when the motor is not driven, the electronic device can change the electrical connection state of multiple batteries to a parallel connection state (e.g., a second state) after a specified time, or maintain the parallel connection state without changing the electrical connection state.

[0120] Figure 9 This is a view illustrating an example of a method of operation in an electronic device according to an embodiment; in the following embodiments, the operations may be performed sequentially, but not necessarily sequentially. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0121] refer to Figure 9 In operation 901, the electronic device according to the embodiment (e.g., Figure 1 , Figure 2 , Figure 3a , Figure 3b and Figure 6 Electronic device 101) can identify multiple batteries (e.g., Figure 3a , Figure 3b and Figure 6 The multiple batteries (311, 313) are in a second state of parallel connection (1S2P connection) (e.g., 2S1P_ENABLE=0). The electronic device can set the default connection of the multiple batteries to parallel connection (e.g., the second state).

[0122] In operation 903, the electronic equipment can identify whether a motor (e.g., Figure 3a , Figure 3b and Figure 6 The electronic device can perform operation 905 if a motor drive event (e.g., motor drive trigger) occurs as a result of the identification; otherwise, the electronic device can perform operation 901.

[0123] In operation 905, the electronic equipment can determine the drive voltage (e.g., approximately 4V to 8V) used to drive the motor. The electronic equipment can automatically determine the optimal drive voltage based on the remaining battery capacity and / or temperature.

[0124] According to an embodiment, the electronic device can identify whether a first state has changed from a parallel connection state to a series connection state based on conditions for comparing the drive voltage for driving the motor with the battery voltage and / or conditions for comparing the battery voltage with a low voltage reference voltage (e.g., 4V).

[0125] In operation 907, the electronic device can identify whether the determined motor drive voltage is greater than or equal to the battery voltage. As a result of the identification, if the determined motor drive voltage is greater than or equal to the battery voltage, the electronic device can identify that the drive voltage used to drive the motor is a high voltage and execute operation 911. If the determined motor drive voltage is less than the battery voltage, the electronic device can identify a first voltage (e.g., about 4V) of low voltage used to drive the motor, maintain the parallel connection of multiple batteries (e.g., second state), and execute operation 909 or operation 913. Here, operation 907 can be omitted when the condition used only for comparing the battery voltage with a low voltage reference voltage (e.g., 4V) is identified.

[0126] In operation 909 (operation 907 - No), the electronic device can identify whether the battery voltage is greater than or equal to a low-voltage reference voltage. As a result of the identification, if the battery voltage is greater than or equal to the reference voltage, operation 913 can be executed, and if the battery voltage is less than the reference voltage, operation 911 can be executed. If the battery voltage is less than the reference voltage, the remaining battery capacity is reduced, therefore the boost circuit (e.g., Figure 3a , Figure 3b , Figure 4 and Figure 6 The input voltage of the boost circuit 323 may decrease. Therefore, the boost circuit requires a higher voltage to apply the determined drive voltage to the motor, potentially reducing efficiency. In operation 909, the electronic device compares the battery voltage with a low-voltage reference voltage, but it can also identify whether to change the connection state based on the remaining battery capacity. For example, if the remaining battery capacity is less than or equal to a threshold level, operation 911 can be performed to switch to the first state, and if the remaining battery capacity exceeds the threshold level, operation 913 can be performed to drive the motor while maintaining the second state, since a high voltage can be supplied to the motor.

[0127] In operation 911 (operation 907 - Yes, operation 909 - No), the electronic device can switch to a first state (e.g., 2S1P_ENABLE=1) by a switching circuit including multiple switches, and connect the series-connected batteries to a boost circuit. The electronic device can recognize that the drive voltage for driving the motor needs to operate at a second voltage (e.g., approximately greater than 4V to 8V or less) that is higher than a reference voltage, and switch back to the first state of connecting the batteries in series to the boost circuit via the switching circuit, causing the boost circuit to apply the second voltage to the motor. Because the boost circuit is connected to the series-connected batteries, a high voltage is applied to the input, thus reducing the difference between the input and output voltages and improving efficiency.

[0128] In operation 913, the electronic device can apply the battery voltage as an input voltage to the boost circuit according to the set connection state (e.g., parallel connection state) or the changed connection state (e.g., series connection state), and use the power (e.g., 10W) ​​of the voltage output from the boost circuit (e.g., the voltage boosted from the input voltage) to drive the motor.

[0129] In operation 915, according to the embodiment, the electronic device can identify whether the motor drive is complete. As a result of the identification, if the motor drive is complete, the electronic device can execute operation 917; otherwise, operation 913 can be executed again.

[0130] In operation 917 (operation 915 - Yes), according to an embodiment, when the motor drive is complete, the electronic device can change or maintain the electrical connection state of the multiple batteries in a parallel connection state (e.g., a second state) via a switching operation of the switching circuit. According to an embodiment, if a change in the parallel connection state is identified in operation 907, and the motor is driven in a series connection state in operations 911 and 913, then in operation 917, the electronic device can switch (e.g., change or restore) from the series connection state (e.g., a first state) to the parallel connection state (e.g., a second state) and connect the multiple batteries in parallel to the boost circuit. According to an embodiment, if a parallel connection state is identified in operation 907, and the motor is driven in a parallel connection state in operation 913, then in operation 917, the electronic device can maintain the parallel connection state as is.

[0131] According to an embodiment, when the motor is not driven, the electronic device can change the electrical connection state of multiple batteries to a parallel connection state (e.g., a second state) after a specified time, or maintain the parallel connection state without changing the electrical connection state.

[0132] Figure 10This is a view illustrating an example of a method of operation in an electronic device according to an embodiment. In the following embodiments, each operation may be performed sequentially, but not necessarily sequentially. For example, the order of operations may be changed, and at least two operations may be performed in parallel.

[0133] refer to Figure 10 In operation 1001, the electronic device according to the embodiment (e.g., Figure 1 , Figure 2 , Figure 3a , Figure 3b and Figure 6 Electronic device 101) can identify multiple batteries (e.g., Figure 3a , Figure 3b and Figure 6 The multiple batteries (311, 313) are in a second state of parallel connection (1S2P connection) (e.g., 2S1P_ENABLE=0). The electronic device can set the default connection of the multiple batteries to parallel connection (e.g., the second state).

[0134] In operation 1003, the electronic equipment can identify whether a motor (e.g., Figure 3a , Figure 3b and Figure 6 The electronic device can perform operation 1005 if a motor drive event (e.g., motor drive trigger) occurs as a result of the identification; otherwise, it can perform operation 1001.

[0135] In operation 1005, the electronic equipment can determine the drive voltage (e.g., approximately 4V to 8V) used to drive the motor. The electronic equipment can automatically determine the optimal drive voltage based on the remaining battery capacity and / or temperature.

[0136] According to an embodiment, the electronic device can identify whether to change from a second state of parallel connection to a first state of series connection based on at least one of the following: conditions for comparing the determined drive voltage with the battery voltage, conditions for comparing the battery voltage with a low-voltage reference voltage (e.g., 4V), or low-temperature operating conditions (e.g., internal or external temperature values).

[0137] In operation 1007, the electronic device can identify whether the determined motor drive voltage is greater than or equal to the battery voltage. As a result of the identification, if the determined motor drive voltage is greater than or equal to the battery voltage, the electronic device can identify that the drive voltage used to drive the motor is a high voltage and execute operation 911. If the determined motor drive voltage is less than the battery voltage, the electronic device can identify a first voltage (e.g., about 4V) of low voltage used to drive the motor, maintain the parallel connection of multiple batteries (e.g., second state), and execute operation 1009 or operation 1015. Here, when the condition used only for comparing the battery voltage with a low voltage reference voltage (e.g., 4V) is identified, operation 1007 can be omitted.

[0138] In operation 1009 (operation 1007 - No), the electronic device can identify whether the battery voltage is greater than or equal to a low-voltage reference voltage. As a result of the identification, if the battery voltage is greater than or equal to the reference voltage, operation 1013 can be executed, and if the battery voltage is less than the reference voltage, operation 1011 can be executed. Here, multiple batteries connected in parallel can have the same voltage through battery balancing. Since the battery voltage of each battery decreases as the remaining battery capacity decreases, the internal resistance increases as the battery voltage decreases, which may lead to a higher voltage drop. If the battery voltage is less than the reference voltage, the boost circuit may have reduced efficiency because a higher voltage boost is required to apply the power of the determined motor drive voltage as the input voltage from the battery decreases. Here, operation 1009 can be omitted when only low-temperature operating conditions are identified.

[0139] In operation 1011 (operation 1007 - Yes, operation 1009 - No), the electronic device can identify whether a low-temperature operating state exists based on temperature values ​​obtained using at least one temperature sensor (e.g., internal and / or external temperature values ​​of the electronic device 101). As a result of the identification, if a low-temperature operating state exists, the electronic device can perform operation 1015, and if a low-temperature operating state does not exist, the electronic device can perform operation 1013.

[0140] In operation 1013 (operation 1007 - Yes, operation 1009 - No, operation 1011 - Yes), the electronic device can switch to a first state (e.g., 2S1P_ENABLE=1) by a switching circuit including multiple switches, and connect the series-connected batteries to a boost circuit. The electronic device can recognize that the drive voltage for driving the motor needs to operate at a second voltage (e.g., approximately greater than 4V to 8V or less) that is higher than a reference voltage, and switch to the first state of connecting the multiple batteries in series to the boost circuit by the switching circuit, so that the boost circuit applies the power of the second voltage to the motor. Because the boost circuit is connected to the series-connected batteries, a high voltage (e.g., a voltage exceeding the reference voltage (4V)) is applied to the input, thus reducing the difference between the input voltage and the output voltage, thereby improving efficiency.

[0141] In operation 1015, the electronic device can apply the battery voltage as an input voltage to the boost circuit according to the set connection state (e.g., parallel connection state) or the changed connection state (e.g., series connection state), and use the power (e.g., 10W) ​​of the voltage output from the boost circuit (e.g., the voltage boosted from the input voltage) to drive the motor.

[0142] In operation 1017, according to the embodiment, the electronic device can identify whether the motor drive is complete. As a result of the identification, if the motor drive is complete, the electronic device can execute operation 1019; otherwise, operation 1015 can be executed again.

[0143] In operation 1019 (operation 1017 - Yes), according to an embodiment, when the motor drive is complete, the electronic device can change or maintain the electrical connection state of multiple batteries in a parallel connection state (e.g., a second state) through the switching operation of the switching circuit. According to an embodiment, if a change in the parallel connection state is identified in operation 1007, and the motor is driven in a series connection state in operations 1013 and 1015, then in operation 1019, the electronic device can switch (e.g., change or restore) from the series connection state (e.g., a first state) to the parallel connection state (e.g., a second state) and connect the multiple batteries in parallel to the boost circuit. According to an embodiment, if a parallel connection state is identified in operation 1007, and the motor is driven in a parallel connection state in operation 913, then in operation 1019, the electronic device can maintain the parallel connection state as is.

[0144] According to an embodiment, when the motor is not driven, the electronic device can change the electrical connection state of multiple batteries to a parallel connection state (e.g., a second state) after a specified time, or maintain the parallel connection state without changing the electrical connection state.

[0145] Figure 11 This is a view illustrating an example of a method of operation in an electronic device according to an embodiment. In the following embodiments, each operation may be performed sequentially, but not necessarily sequentially. For example, the order of operations may be changed, and at least two operations may be performed in parallel.

[0146] refer to Figure 11 In operation 1101, the electronic device according to the embodiment (e.g., Figure 1 , Figure 2 , Figure 3a , Figure 3b and Figure 6 Electronic device 101) can identify multiple batteries (e.g., Figure 3a , Figure 3b and Figure 6 The multiple batteries (311, 313) are in a second state of parallel connection (1S2P connection) (e.g., 2S1P_ENABLE=0). The electronic device can set the default connection of the multiple batteries to parallel connection (e.g., the second state).

[0147] In operation 1103, the electronic equipment can identify whether a motor (e.g., Figure 3a , Figure 3b and Figure 6 The electronic device can perform operation 1105 if a motor drive event (e.g., motor drive trigger) occurs as a result of the identification; otherwise, it can perform operation 1101.

[0148] In operation 1105, the electronic equipment can determine the drive voltage (e.g., approximately 4V to 8V) used to drive the motor. The electronic equipment can automatically determine the optimal drive voltage based on the remaining battery capacity and / or temperature.

[0149] In operation 1107, the electronic device can identify whether it is connected to an external charging device and whether it is receiving power from the external charging device. As a result of this identification, if a charging state exists, the electronic device can activate the connection between the external charging device and the boost circuit (e.g., ...). Figure 3a , Figure 3b , Figure 4 and Figure 6 The switches between the boost circuit 323 and the other circuit (e.g., Figure 6 The sixth switch 620) is activated and operation 1113 is executed. As a result of the identification, if no charging state exists, the electronic device can execute operation 1109. This can be performed... Figure 8 Operation 807 Figure 9 Operations 907 and 909 and Figure 10Operations 1007 to 1011. According to an embodiment, the electronic device can identify whether to change from a second state of parallel connection to a first state of series connection based on at least one of the following: conditions for comparing the drive voltage for driving the motor with the battery voltage, conditions for comparing the battery voltage with a low-voltage reference voltage (e.g., 4V), or low-temperature operating conditions (e.g., internal temperature value or external temperature value).

[0150] In operation 1109, the electronic device can identify whether it is necessary to change the connection state of multiple batteries. As a result of the identification, if it is identified that the connection state needs to be changed, operation 1111 can be executed; otherwise, operation 1115 can be executed to drive the motor, such that while maintaining the second state, since the charging voltage is used as the input voltage of the boost circuit, the boost circuit drives the motor with the determined drive voltage. According to an embodiment, when the electronic device executes operation 1109, specifically, as follows... Figure 8 Operation 807 Figure 9 Operations 907 and 909, or Figure 10 In operations 1007 to 1011, the electronic device can identify whether it is necessary to change the electrical connection status of multiple batteries.

[0151] In operation 1111 (operation 1109 - Yes), the electronic device can connect multiple batteries in series to the boost circuit through the switching operation of the switching circuit.

[0152] In operation 1113, the electronic device can apply the battery voltage or charging voltage as an input voltage to the boost circuit according to the set connection state (e.g., parallel connection state) or the changed connection state (e.g., series connection state), and use the power (e.g., 10W) ​​of the voltage output from the boost circuit (e.g., the voltage boosted from the input voltage) to drive the motor.

[0153] In operation 1115, according to the embodiment, the electronic device can identify whether the motor drive is complete. As a result of the identification, if the motor drive is complete, the electronic device can execute operation 1117; otherwise, operation 1113 can be executed again.

[0154] In operation 1117 (operation 1115 - Yes), according to an embodiment, when the motor drive is complete, the electronic device can change or maintain the electrical connection state of the multiple batteries in a parallel connection state (e.g., a second state) through the switching operation of the switching circuit. According to an embodiment, if a change in the parallel connection state is identified in operation 1109, and the motor is driven in a series connection state in operations 1111 and 1113, then in operation 1117, the electronic device can switch (e.g., change or restore) from the series connection state (e.g., a first state) to the parallel connection state (e.g., a second state) and connect the multiple batteries in parallel to the boost circuit. According to an embodiment, if a maintenance of the parallel connection state is identified in operation 1109, and the motor is driven in a parallel connection state in operation 1113, then in operation 1117, the electronic device can maintain the parallel connection state as is.

[0155] According to an embodiment, when the motor is not driven, the electronic device can change the electrical connection state of multiple batteries to a parallel connection state (e.g., a second state) after a specified time, or maintain the parallel connection state without changing the electrical connection state.

[0156] Figure 12 This is a view illustrating an example of a method of operation in an electronic device according to an embodiment; and

[0157] refer to Figure 12 When an event occurs that is used to move the motor (e.g., Figure 3a , Figure 3b and Figure 6 When the driving state of the motor 321 switches to a always high voltage state, the electronic device (e.g., according to the embodiment) Figure 1 , Figure 2 , Figure 3a , Figure 3b and Figure 6 Electronic device 101) can hold multiple batteries (e.g., Figure 3a , Figure 3b and Figure 6 The second state of the parallel connection (1S2P connection) of multiple batteries 311, 313) is changed to the first state of the series connection, and is changed by a switching circuit (e.g., Figure 4 The switching operation of the switching circuit 330 connects multiple batteries in series to the boost circuit (e.g., Figure 3a , Figure 3b , Figure 4 and Figure 6(Boost circuit 323). According to an embodiment, in order to change to a always high voltage state, the electronic device can obtain display status information (e.g., dust introduction into the rack, mechanism failure (bending), or display failure (crack)) and / or motor status information (e.g., reduction in motor drive force), and based on the obtained display status information and / or motor status information, identify a state that requires high voltage drive due to increased curling or sliding friction and reduced thrust of the flexible display.

[0158] According to an embodiment, an electronic device can display a drive battery setting screen 1201 on a flexible display upon user request, allowing the user to set a change to a always high voltage state. When the electronic device receives user input for a selection of an object 1211 included in the battery setting screen 1201 for selecting motor drive voltage performance, the electronic device can display an extended screen 1203 from the battery setting screen 1201. Here, the battery setting screen 1201 may be an example for accessing a motor voltage setting screen related to motor drive performance, but is not limited thereto. The extended screen 1203 may include, but is not limited to, a first object (e.g., automatic) 1221 and a second object (e.g., manual) 1223 for selecting motor drive voltage performance, and may also include other necessary objects. According to an embodiment, when the electronic device receives selection input for the second object (e.g., manual) 1223 included in the extended screen 1203 (e.g., a toggled screen or a pop-up screen), the electronic device can change to a always high voltage state, such that the motor is always driven at a high voltage. According to an embodiment, when the electronic device receives a selection input or a specified gesture input for the second object (e.g., manually) 1223, the electronic device can display a guidance message on the extended screen 1203 (e.g., "It is recommended to set this when it is determined by recognizing terminal status information that the motor drive force is reduced or the sliding friction is increased, and according to user settings, the motor is always driven at maximum output (high voltage in series with the motor)"). Not limited to this, the guidance message (e.g., information, text, or description) can be displayed in an area near the second object 1223.

[0159] When the electronic device according to the embodiment receives selection input for a first object (e.g., automatic) 1221 included in the extended screen 1203, the electronic device can automatically determine the optimal drive voltage and drive the motor based on conditions such as remaining battery capacity (e.g., battery voltage) and / or low-temperature operation settings. According to the embodiment, the electronic device may display a guidance message (e.g., "The optimal motor drive voltage type is determined by taking into account battery voltage, remaining capacity, temperature, whether charging, etc.") in an area near the first object (e.g., automatic) 1221 or in the extended screen 1203. Not limited to this, when receiving selection input or specified gesture input for the first object (e.g., automatic) 1221, a guidance message (e.g., information, text, or description) may be displayed.

[0160] According to an embodiment, when the electronic device receives a selection input from a first object (e.g., automatic) 1223 included in the extended screen 1203, the electronic device can perform a combination Figures 7 to 11 The operation method is described, therefore a detailed description of the operation is omitted.

[0161] Figure 13 This is a view illustrating the structure of an electronic device according to an embodiment.

[0162] refer to Figure 12 and Figure 13 According to the embodiment, the electronic device 101 (e.g., Figure 1 , Figure 2 , Figure 3a , Figure 3b and Figure 6 The electronic device 101 may include multiple batteries 311, 313, a motor 321, a motor driver 322, a boost circuit 323, and a power management module 341. The electronic device 101 can connect the multiple batteries 311, 313 in series, allowing the motor 321 to be driven under a consistently high voltage condition. Here, each of the multiple batteries 311, 313, boost circuit 323, motor driver 322, motor 321, and power management module 341 is combined with... Figure 3a and Figure 3b The structures and operations described are the same or similar, therefore detailed descriptions are omitted. Figure 13 In the diagram, line 1311, which shows the series connection of multiple batteries 311, 313, can be a simplified electrical connection line used to describe the series connection of batteries 311, 313.

[0163] According to an embodiment, the electronic device 101 may further include a switch (e.g., a seventh switch) 1301 connected to the boost circuit 323 and a voltage divider 1303 that distributes battery power (e.g., voltage) output from the series-connected batteries 311, 313 to the boost circuit 323 and the power management module 341. One end of the switch 1301 is connected to the voltage divider 1303, and the other end may be connected to the boost circuit 323. Here, the voltage divider 1303 may replace... Figure 3a and Figure 3b The second power management module 243, or may be additionally added to the combination Figure 3a and Figure 3b In the described electronic device structure, voltage divider 1303 can distribute the high voltage applied from the first battery 311 and the second battery 313 connected in series to the power management module 341 and the boost circuit 323 connected to switch 1301.

[0164] According to an embodiment, when the electronic device 101 receives a selection input via the processor for a second object (e.g., manual (always high voltage)) 1223 or a first object (e.g., automatic) 1221 included in the extended screen 1203, the electronic device 101 can turn on a switch 1301 (e.g., a seventh switch) connected to the voltage divider 1303 to connect the voltage divider 1303, which is connected in series with the first battery 311 and the second battery 313, to the boost circuit 323.

[0165] Figure 14a and Figure 14b This is a graph illustrating an example of the voltage drop and efficiency of a boost circuit in an electronic device according to an embodiment.

[0166] When the electronic device according to the embodiment (e.g., Figure 1 , Figure 2 , Figure 3a , Figure 3b , Figure 6 and Figure 13 When the electronic device 101 sets the battery voltage of each battery 311, 313 to, for example, 3.4V and sets the power consumption of the boost circuit 323 (or motor 321) to, for example, 10W and performs a simulation, it can obtain, as shown below. Figure 14a The results are shown. In the simulation results, the A section (parallel) and the B section (series) are distinguished. In the case of the A section (e.g., the existing one), it can be identified that during the peak system current range (e.g., 9A) during motor drive, the system voltage (Vsys) drops to 2V or lower (e.g., 1.68V), resulting in a power outage.

[0167] In the simulation results, as in section B (series) (e.g., enhanced), when the batteries are connected in series and a high voltage is applied to the boost circuit during motor drive, the current consumption of the boost circuit is identified as a reduced value (e.g., 1.58A) compared to section A (e.g., the existing 3.70A). Therefore, losses are reduced and voltage drops can be mitigated. Furthermore, in section B, the system voltage (Vsys) is 2V or higher (e.g., 2.02V) in the system current peak range (e.g., 9A), so power outages are unlikely to occur. Because multiple batteries 311 and 313 are connected in series in section B, the input voltage of the boost circuit is identified as higher than in section A (e.g., the existing 2.69V) (e.g., 6.32V), and the battery voltages of the multiple batteries 311 and 313 are higher than in section A (e.g., the existing 3.62V) (e.g., 3.73V).

[0168] According to an embodiment, the electronic device can... Figure 14a The simulation results show that applying a high voltage to the input of the boost circuit by connecting the battery in series during motor drive has the effect of increasing voltage drop, so that the electronic device can drive the motor while ensuring system stability even at low battery levels.

[0169] According to embodiments, since the smaller the difference between the output voltage and the input voltage, the higher the efficiency of the boost circuit, the efficiency may decrease if the input voltage is low when the boost circuit attempts to output a high voltage. According to embodiments of this disclosure, when a high voltage is applied to the boost circuit from multiple batteries connected in series or a charging voltage (e.g., V) is applied from an external charging device... BUS At 9V, it can be seen that, Figure 14b As shown in the specific range 1410, when a high voltage (e.g., 7.6V, 11.4V, or 16V) is applied, the boost circuit can achieve higher efficiency compared to 4V. For example, when 4V is applied as the boost input voltage, the boost circuit may boost to 5V to output a specified output voltage (e.g., 9V). When 7.6V is applied, the boost circuit may boost to 1.6V to output a specified output voltage (e.g., 9V). Therefore, when 7.6V is applied, the boost circuit can achieve higher efficiency than 4V because the difference between the input and output voltages is reduced.

[0170] The electronic device according to the embodiments can minimize the voltage drop of multiple batteries, improve the efficiency of the boost circuit, and ensure the stability of the system power.
