Description

Power control method and electronic device for executing the same

Technical Field

Various embodiments relate to a power control method and an electronic device for performing the power control method.

Background

A shipment mode (ship mode) may shut off all blocks (or modules) in an Integrated Circuit (IC) of an electronic device and may remove leakage current of the electronic device by opening a switch between a battery of the electronic device and an internal power system of the electronic device.

Since no leakage current occurs in the shipping mode, the electronic device may minimize power consumed by the interface power management IC (IF PMIC), the charging module (or charger), and/or the system. In an electronic device in a shipping mode, either a wired or wireless charge may need to be identified, a specific signal may need to be applied, or a power key of the electronic device may need to be pressed to cancel the shipping mode.

The force shipping mode may be applied when the electronic device is being shipped. Forced shipping mode may refer to setting an electronic device to a shipping mode using a shipping mode command through an inter-integrated circuit (I2C) or other channel regardless of the voltage level of the battery.

Compared to the case where the shipment mode is not applied, the leakage current can be minimized from the point in time when the electronic device enters the forced shipment mode, and the time taken to reach the overdischarge of the battery can be significantly prolonged.

Disclosure of Invention

Technical proposal

By using inter-integrated circuit I2C or other channels to set the electronic device into a forced shipping mode by command before releasing the electronic device after it is manufactured, leakage current of the electronic device can be minimized and the time to overdischarge the battery can be prolonged, so that the risk of battery swelling can be reduced even if the electronic device is kept in an inbox state for a long period of time. However, when a user holds the electronic device for a long time after cutting off the power of the electronic device, leakage current of the electronic device may not be minimized and there is a risk of overdischarge of the battery.

In the case where the electronic device is used by a user, various android Application Packages (APKs) and programs may be installed in the electronic device according to the use condition of the user and according to the use condition of the power-off sequence, for example, the time to completely cut off the power of the electronic device may be prolonged according to the system operation or the APK operation when the power is cut off. In the case where the electronic device is in use, since the time of the power-off sequence operation may vary depending on the use condition, the power-off operation may not be normally terminated, and when a forced shipping mode for entering a shipping mode after a predetermined period of time has elapsed is applied, a sudden power-off event may occur. When the shipping mode is entered before the power down operation is completed, a malfunction or damage of an Integrated Circuit (IC) may be caused in the electronic device.

In the case of a structure in which the system and the battery are separated from each other and controlled separately, power may not be directly supplied from the battery to an electricity meter (fuel gauge) IC, and in the case of a structure in which power is supplied from the system side, if the electronic device enters a shipping mode every time the user cuts off the power of the electronic device, the electricity meter IC may be reset. Since the fuel gauge that has been reset when canceling the shipping mode of the electronic device estimates an initial state of charge (SOC) based on the terminal battery voltage, a problem of a change in SOC displayed through a User Interface (UI) before and after cutting off the power of the electronic device may occur.

According to various embodiments disclosed in the present disclosure, there are provided a power control method of monitoring a voltage of a battery after a power-off operation and setting an electronic device to a shipping mode when the voltage of the battery after cutting off power is less than or equal to a voltage to enter the shipping mode, and an electronic device for performing the power control method.

According to various embodiments disclosed in the present disclosure, there are provided a power control method for entering a shipping mode depending on a voltage level of a battery after a user cuts off power of an electronic device and ignores the electronic device for a long period of time, and an electronic method for executing the power control method.

According to various embodiments disclosed in the present disclosure, there are provided a power control method of storing power gauge (power gauge) data and loading the stored power gauge data when a shipping mode is canceled, and an electronic device for performing the power control method.

According to various embodiments disclosed in the present disclosure, there are provided a power control method of setting an electronic device to a shipping mode when a set period of time has elapsed after a power-off operation, and an electronic device for executing the power control method.

A power control method according to various embodiments may include: receiving user input from a user to turn off power to the electronic device; identifying a voltage of the battery upon receiving a user input; determining a reference voltage to enter a shipping mode to prevent the battery from discharging due to leakage current based on the set margin voltage and the voltage of the battery when the user input is received; cutting off the power of the electronic device; monitoring a voltage of the battery after cutting off power to the electronic device; and setting the electronic device to a shipping mode based on the monitored voltage of the battery and the reference voltage.

A power control method according to various embodiments may include: receiving user input by a user to set the electronic device to a shipping mode to prevent discharge of the battery due to leakage current; cutting off the power of the electronic device; storing power meter data relating to the state of the battery in a memory; and setting the electronic device to a shipping mode.

An electronic device according to various embodiments may include: a battery; a processor; and a power management module configured to control power output by the battery, wherein the processor is configured to: receiving user input from a user to turn off power to the electronic device; identifying a voltage of the battery upon receiving a user input; determining a reference voltage to enter a shipping mode to prevent the battery from discharging due to leakage current based on the set margin voltage and the voltage of the battery when the user input is received; cutting off power to the electronic device, wherein the power management module is further configured to: monitoring a voltage of the battery after cutting off power to the electronic device; and setting the electronic device to a shipping mode based on the monitored voltage of the battery and the reference voltage.

A power control method according to various embodiments may include: identifying a signal to shut off power to the electronic device; cutting off the power of the electronic device; timing a set first period of time from when a signal to cut off power is recognized; and setting the electronic device to a shipping mode to prevent the battery from discharging due to leakage current.

Advantageous effects

The external power source may be connected to the electronic device 101 wirelessly, for example, by wires via connection 178 or via antenna module 197.

For example, the power regulator 220 may generate power slices having different voltage levels or different current levels by adjusting the voltage levels or current levels of the power supplied from the external power source or the battery 189. The power regulator 220 may regulate the voltage level or current level of the power supplied from the external power source or battery 189 to a different voltage level or current level suitable for each of some components included in the electronic device 101. According to one embodiment, the power regulator 220 may be implemented in the form of a Low Dropout (LDO) regulator or a switching regulator. The power meter 230 may measure usage state information (e.g., capacity, number of charge or discharge, voltage, or temperature of the battery 189) about the battery 189.

The power management module 188 may determine state of charge information (e.g., lifetime, over-voltage, low voltage, over-current, over-charge, over-discharge, over-temperature, short circuit, or bulge) related to the charging of the battery 189 based at least in part on the measured state of use information about the battery 189 using, for example, the charging circuit 210, the power regulator 220, or the power meter 230. The power management module 188 may determine whether the state of the battery 189 is normal or abnormal based at least in part on the determined state of charge information. If the state of the battery 189 is determined to be abnormal, the power management module 188 may adjust the charging of the battery 189 (e.g., reduce the charging current or voltage, or stop the charging). According to one embodiment, at least some of the functions of the power management module 188 may be performed by an external control device (e.g., the processor 120).

According to one embodiment, the battery 189 may include a Protection Circuit Module (PCM) 240.PCM 240 may perform one or more of various functions (e.g., a pre-shutdown function) to prevent performance degradation or damage of battery 189.

According to various embodiments, processor 120 may include an Application Processor (AP) 120-1 and an AP Power Management Integrated Chip (PMIC) 120-2. For example, AP PMIC 120-2 may use power input by battery 189 to supply power to components of electronic device 101, such as AP 120-1 and/or an Integrated Circuit (IC). For example, AP PMIC 120-2 may convert power input by battery 189 to supply power required by components of electronic device 101. For example, the voltage of the power required by the AP 120-1 may vary depending on the internal configuration of the AP 120-1 and/or the operating state of the AP 120-1, and the AP PMIC 120-2 may supply the power required by the internal configuration of the AP 120-1 by converting the input power.

According to various embodiments, the power management module 188 may include a charging circuit 260, a power meter 230, a switch 250, a power control module 270, an interface module 275, and a microcontroller unit (MCU) 290.

For example, the charging circuit 260 may charge the battery 189 using power input from the outside, or may supply power to the processor 120. The operation of the charging circuit 260 may be controlled by a power control module 270. For example, based on the control of the power control module 270, power may be supplied to the battery 189 and/or the processor 120 by converting external power input to the charging circuit 260. For example, the charging circuit 260 may include a pulse width modulation driver (PWM DRV) 261 and a buck converter (buck converter) 262. For example, the PWM DRV 261 may be operated by a control signal provided by the power control module 270. The PWM DRV 261 may be operated based on the control signal, and the PWM DRV 261 may supply external power input from the adapter 300 (e.g., TA of fig. 3) to the buck converter 262, and the supplied external power may be converted by the buck converter 262.

For example, switch 250 may form a path to supply power from battery 189 to components in electronic device 101. For example, when the switch 250 is in an on state, power may be supplied from the battery 189 to the processor 120.

The embodiment of fig. 3 shows a case in which the target to which power is to be supplied from the power management module 188 is the processor 120, such as a case in which power input from the outside is used to charge the battery 189 and/or is supplied to the processor 120 by converting the power using the charging circuit 260 or a case in which power charged in the battery 189 is used to supply power to the processor 120.

The embodiment of fig. 3 may correspond to one of various embodiments and unlike the embodiment of fig. 3, power output from battery 189 may be supplied to components of electronic device 101, such as ICs other than processor 120, a display module (e.g., display module 160 of fig. 1), a sound output module (e.g., sound output module 155 of fig. 1), a communication module (e.g., communication module 190 of fig. 1), an audio module (e.g., audio module 170 of fig. 1), a sensor module (e.g., sensor module 176 of fig. 1), a haptic module (e.g., haptic module 179 of fig. 1), or a camera module (e.g., camera module 180 of fig. 1). In addition to the above examples, the power output from the battery 189 may also be supplied to components included in the electronic device 101, such as the memory 130, an antenna module (e.g., the antenna module 197 of fig. 1), and an input module (e.g., the input module 150 of fig. 1).

For example, when the voltage amplitude to be supplied to the components in the electronic device 101 is different from the voltage amplitude output from the power management module 188 and/or the battery 189, the electronic device 101 may include a conversion module configured to convert the power output from the power management module 188 and/or the battery 189.

For example, the processor 120 may receive user input to shut off power to the electronic device 101. The processor 120 may receive a user input a to shut off power to the electronic device 101 through a power key input of the electronic device 101 or an interface of a display module (e.g., display module 160 of fig. 1).

For example, the processor 120 may identify the voltage of the battery 189 upon receiving the user input a. For example, power control module 270 may identify the voltage of battery 189. When user input is received, processor 120 may identify the voltage of battery 189 from power control module 270.

For example, the processor 120 may set a reference voltage to enter the shipping mode. For example, when receiving user input a to shut off power to the electronic device 101 and a set margin voltage, the processor 120 may determine a reference voltage based on the identified voltage of the battery 189.

According to one embodiment, when the maximum charge voltage of the battery 189 is 4.4V and the off-voltage of the PCM 240 is 2.5V, the electronic device 101 may determine the reference voltage from 20 voltage levels in units of 0.1V within a range between the maximum charge voltage and the off-voltage. For example, when the voltage of the identified battery 189 is 4.0V and the set margin voltage is 300mV, the electronic device 101 may determine that the reference voltage is 3.7V. In another example, when the voltage of the identified battery 189 is 3.94V and the set margin voltage is 300mV, the electronic device 101 may determine the reference voltage to be 3.6V,3.6V being a voltage level smaller than a voltage obtained by subtracting the margin voltage from the voltage of the battery 189.

According to various embodiments, the processor 120 may determine the reference voltage such that the reference voltage is greater than or equal to the cutoff voltage. As described above, the processor 120 may determine the reference voltage according to a voltage amplitude obtained by subtracting the margin voltage from the voltage of the battery 189 when the user input is received.

For example, the processor 120 may set the margin voltage by considering the cutoff voltage of the battery 189 and the voltage range of the battery 189 when the electronic device 101 is in normal operation. For example, when the voltage range of the battery 189 is greater than or equal to 3.3V and less than or equal to 4.4V and the cutoff voltage of the battery 189 is 2.5V when the electronic device 101 is in normal operation, the processor 120 may set the margin voltage to be less than or equal to 0.8V,0.8V being a voltage amplitude obtained by subtracting the cutoff voltage of the battery 189 by 2.5V from the minimum voltage amplitude of the voltage range of the battery 189, 3.3V. The processor 120 may determine the reference voltage to be greater than or equal to the cutoff voltage by using a margin voltage set by considering the voltage range of the battery 189 and the cutoff voltage of the battery 189.

An example of determining the reference voltage from the voltage level in set units between the maximum charge voltage of the battery 189 and the cut-off voltage of the PCM 240 based on the margin voltage and the voltage of the battery 189 may be one of various embodiments, and the electronic device 101 may determine the reference voltage in a different method from the above-described example. In another example, when the voltage of the battery 189 is 3.94V and the set margin voltage is 300mV, the reference voltage may be determined to be 3.64V, or when the voltage of the battery 189 is greater than or equal to 3V and less than or equal to 3.3V, the reference voltage may be determined to be 2.7V.

According to various embodiments, the electronic device 101 may prevent the electronic device 101 from being set to a shipping mode before receiving a user input a to shut off power to the electronic device 101. Since the user uses the electronic device 101 before receiving a user input to cut off power, it may be necessary to supply power to components of the electronic device 101.

For example, the electronic device 101 may set the reference voltage before receiving a user input to shut off power by considering the cutoff voltage of the battery 189. For example, the cut-off voltage of the battery 189 may be a voltage at which the PCM 240 operates to prevent overdischarge of the battery 189.

For example, the electronic device 101 may shut off power. Shutting off power to the electronic device 101 may indicate that a program or Operating System (OS) run by the processor 120 is terminated and power to components in the electronic device 101, such as the following, is blocked: processor 120, IC, display module, sound output module, communication module, audio module, sensor module, haptic module, or camera module.

For example, the power management module 188 may monitor the voltage of the battery 189 after shutting off power to the electronic device 101. After the power of the electronic device 101 is cut off, power may not be supplied to components in the electronic device 101 (such as the processor 120), but the voltage of the battery 189 may drop due to leakage current. For example, after cutting off power, the voltage of battery 189, as monitored by power management module 188, may gradually decrease.

For example, the power management module 188 may determine whether to change the electronic device 101 to be in the shipping mode based on the monitored voltage of the battery 189 and the reference voltage to enter the shipping mode.

For example, when the monitored voltage of the battery 189 is less than or equal to the reference voltage, the power management module 188 may set the electronic device 101 to the shipping mode. For example, when the voltage of the battery 189 is 3.9V and the set reference voltage is 3.6V upon receiving a user input to turn off the electronic apparatus 101, the voltage of the battery 189 may gradually decrease due to leakage current after the power of the apparatus is cut off. When the voltage of the monitored battery 189 is less than or equal to 3.6V, the power management module 188 may set the electronic device 101 to a shipping mode. For example, a case where the voltage of the battery 189 becomes less than or equal to the reference voltage because the voltage decreases due to the leakage current may represent a state where the electronic device 101 is not used for a long time.

For example, the power management module 188 may set the electronic device 101 to the shipping mode when the monitored voltage of the battery 189 exceeds or equals the set anti-shake time while maintaining less than or equal to the reference voltage. For example, the anti-shake time may be set to one of 1 second, 4 seconds, 16 seconds, 32 seconds, and 64 seconds. The above example of the anti-shake time may be one of various embodiments, and as an example different from the above example, the anti-shake time may be set differently, such as 1 hour or 24 hours.

For example, the power management module 188 may check the leakage current of the electronic device 101 to determine that the power of the electronic device 101 was shut off when entering the shipping mode. For example, the leakage current of the electronic device 101 may be the current output from the battery 189 when the electronic device 101 is turned off.

The power management module 188 in various embodiments may control the operation of the switch 250. The power management module 188 may set the electronic device 101 to the shipping mode by controlling operation of the switch 250. For example, switch 250 may be connected to battery 189 and may transmit power to electronic device 101. For example, the switch 250 may form a path to transmit power output by the battery 189 to components of the electronic device 101 (e.g., the processor 120, the IC, the display module 160, the sound output module 155, the communication module 190, the audio module 170, the sensor module 176, the haptic module 179, and the camera module 180).

For example, the power management module 188 may cause the switch 250 to open. When switch 250 is opened, the path by which leakage current flows from battery 189 to components of electronic device 101 may be blocked. For example, the power management module 188 may cause the switch 250 to open and may set the electronic device 101 to the shipping mode.

Electronic device 101 in various embodiments may store power meter data related to the state of battery 189 in memory 130 or 231. For example, the power management module 188 may use the MCU 290 to store power meter data in the memory 130 or 231 of the power meter 230. For example, the power management module 188 may use the MCU 290 to store the power count in the memory 130 or 231.

In another example, the processor 120 may store the power count in the memory 130. For example, the processor 120 may identify power meter data through the interface module 275 of the power management module 188 and may store the identified power meter data in the memory 130.

When a power key is input or the adapter 300 is inserted, the shipping mode of the electronic device 101 in various embodiments may be canceled. For example, the power management module 188 may recognize that a power key is input in the shipping mode or that external power is input through the adapter 300.

For example, the power management module 188 may receive a power key input when the power key is input. For example, the power control module 270 of the power management module 188 may be connected to a power key. For example, when the adapter 300 is plugged in, the power management module 188 may recognize that external power is input through the adapter 300. For example, the power control module 270 of the power management module 188 may identify that external power is input by sensing the voltage and/or the voltage of the input external power. For example, when a power key is entered or adapter 300 is inserted, power management module 188 may cancel the shipping mode of electronic device 101 by having switch 250 turned on.

When the shipping mode is canceled, the electronic device 101 in various embodiments may load the power meter data from the memory 130 or 231. Loading power meter data from memory 130 or 231 may refer to identifying power meter data stored in memory 130 or 231.

For example, when the shipping mode of the electronic device 101 is canceled, the power meter 230 may load power meter data stored in the memory 231 of the power meter 230. In another example, when the shipping mode of the electronic device 101 is canceled, the power control module 270 may identify the power meter data stored in the memory 130 through the interface module 275, and the power meter 230 may load the power meter data from the power control module 270.

According to various embodiments, the power meter data may be prevented from being initialized by storing the power meter data in the memory when the electronic device 101 is set to the shipping mode or before the electronic device 101 is set to the shipping mode, and loading the power meter data when the shipping mode of the electronic device 101 is canceled or after the shipping mode of the electronic device 101 is canceled.

The power meter 230 in various embodiments may be electrically connected to the processor 120 and/or the battery 189. For example, the processor 120 may be electrically connected to the power meter 230 and may identify power meter data, which is information about the state of the battery 189. In another example, the processor 120 may communicate with the power control module 270 through the interface 275 and may identify power meter data stored in the power meter 230 from the power control module 270.

For example, power meter 230 may be electrically connected to battery 189 and may measure usage status information (e.g., capacity of battery 189, number of charge and discharge cycles, voltage, or temperature) regarding battery 189.

The electronic device 101 in various embodiments may control the electronic device 101 to prevent the electronic device 101 from being set to a shipping mode in operation before receiving a user input to shut off power to the electronic device 101. Since the user uses the electronic apparatus 101 before receiving the user input to cut off the power, the electronic apparatus 101 can control the electronic apparatus 101 to prevent the electronic apparatus 101 from being set to the shipping mode.

For example, when the electronic device 101 is turned on, the reference voltage may be set to a default level. For example, when the electronic device 101 is operating at a voltage between 3.4V and 4.4V of the battery 189, the reference voltage set to the default level may be a low value, such as 2.6V.

For example, the electronic device 101 may set the reference voltage by considering the cutoff voltage of the battery 189. For example, when electronic device 101 is operating at a voltage of between 3.4V and 4.4V of battery 189, electronic device 101 may be automatically turned off until the voltage of battery 189 reaches 3.4V. After the electronic device 101 is turned off, the battery 189 may be discharged for a long period of time. For example, when the voltage of the battery 189 reaches a cut-off voltage, the PCM 240 may operate to prevent overdischarge of the battery 189. For example, when the cutoff voltage of the battery 189 is 2.5V, the electronic device 101 may set a reference voltage, such as 2.6V or 2.7V, by considering the cutoff voltage of the battery 189.

For example, when the reference voltage is set by considering the off-voltage of the battery 189 and the user uses the electronic device 101, the electronic device 101 may not be set to the shipping mode.

For example, when the reference voltage is set by considering the off-voltage of the battery 189 and the battery 189 reaches the reference voltage as the battery 189 is continuously discharged after the electronic device 101 is automatically turned off, the electronic device 101 may be set to the shipping mode.

For example, the electronic device 101 may disable the functionality of the power management module 188 to set the electronic device 101 in the shipping mode. For example, when the power of the electronic device 101 is turned on and the user uses the electronic device 101, the power management module 188 may disable the function to set the electronic device 101 in the shipping mode. For example, when an input is received from a user to shut off power to the electronic device 101, the electronic device 101 may enable the functionality of the power management module 188 to set the electronic device 101 to a shipping mode.

Referring to fig. 3, the electronic device 101 in one embodiment may identify a signal to shut off power to the electronic device 101. For example, the electronic device 101 may identify a signal to shut off power to the electronic device 101 from a user input to shut off power to the electronic device 101, such as a power key input (e.g., power key press of fig. 3) or a display and touch interface (e.g., display and touch interface of fig. 3).

For example, the electronic device 101 may determine that the state of the electronic device 101 changes within a set second period of time. When the state of the electronic device 101 is not changed within the second period of time, the electronic device 101 may output a signal to cut off power.

For example, the electronic device 101 may determine whether the state of the electronic device 101 has changed based on screen touch input through a display module (e.g., display module 160 of fig. 1), key input such as a power key or a volume adjustment key, connection to a wired or wireless charger, an operating state of the electronic device 101 or an external environmental state collected by a sensor module (e.g., sensor module 176 of fig. 1), and movement of a terminal (e.g., movement of a terminal collected by a gyro sensor using the sensor module 176).

For example, when there is no screen touch input, key input, connection to a charger, change in the operating state of the electronic device 101, and change in the movement of the terminal for the second period of time, it may be determined that there is no change in the state of the electronic device 101.

For example, when a signal to cut off power is recognized, the electronic apparatus 101 may perform an operation to cut off power of the electronic apparatus 101. The electronic device 101 may terminate the running program or OS and may block power supplied to components in the electronic device 101 such as the processor 120, the IC, and the display module 160.

For example, the electronic device 101 may time a set first period from the time when the signal to cut off power is identified. For example, when the processor 120 recognizes a signal to shut off power, the processor 120 may send a control signal to the power management module 188. For example, the processor 120 may send control signals to the power management module 270 through the interface module 275.

For example, the power management module 188 may time the set first period based on the control signal. For example, the power control module 270 of the power management module 188 may time the set first period of time.

For example, the electronic device 101 may determine the first time period based on the voltage magnitude of the battery 189. For example, the processor 120 may identify the voltage magnitude of the battery 189 upon identifying a signal to shut off power. For example, the processor 120 may determine a first period of time that is positively correlated to the voltage amplitude of the battery 189 when identifying the signal to shut off power.

For example, the voltage range of battery 189 may be between about 3.3V and about 4.4V. For example, in the case where the voltage amplitude of the battery 189 is 4.4V when the signal to cut off the power is recognized, the processor 120 may set the first period of time to 48 hours. For example, when the voltage amplitude of the battery 189 is 3.3V at the time of recognizing the signal to cut off the power, the processor 120 may determine the first period of time to be 24 hours.

In the above example, the first period of time determined based on the voltage range of the battery 189 and the voltage amplitude of the battery 189 is an example, and the example is not limited thereto.

For example, the electronic device 101 may set the electronic device 101 to the shipping mode after the first period of time has elapsed. For example, after the first period of time has elapsed, the power control module 270 may set the electronic device 101 to the shipping mode. For example, the power control module 270 may set the electronic device 101 to the shipping mode by controlling the operation of the switch 250.

For example, after the first period of time has elapsed, the electronic device 101 may set the electronic device 101 to the shipping mode by opening the switch 250. The power management module 188 may cause the switch 250 to open. When switch 250 is opened, the path by which leakage current flows from battery 189 to components of electronic device 101 may be blocked. The power management module 188 may set the electronic device 101 to the shipping mode by opening the switch 250.

For example, electronic device 101 may store power meter data in memory 231 that relates to the state of battery 189. For example, the power control module 270 may store the power count in the memory 231. For example, the power control module 270 may store the power meter data in the memory 231 simultaneously with the operation of setting the electronic device 101 to the shipping mode, or may store the power meter data in the memory 231 before or after the operation of setting the electronic device to the shipping mode.

For example, when a power key is entered or an adapter is inserted during a first period of time, the electronic device 101 may stop timing the first period of time.

For example, the electronic device 101 may set a mode to set the electronic device 101 to a shipping mode based on user input. For example, when set to the mode to set to the shipping mode, the electronic apparatus 101 may be set to the shipping mode after a first period of time has elapsed after the power is cut off. For example, when the mode to set to the shipping mode is not set, the electronic device 101 is not set to the shipping mode even if the first period of time elapses after the power is cut off.

For example, when power to the electronic device 101 is turned off based on user input, the electronic device 101 may provide an interface to select a mode to set to a shipping mode through the display module 160. For example, when a user desires to cut off power to the electronic device 101 by entering a power key, an interface may be provided to select power down, reboot, power down, and enter a shipping mode.

For example, when a signal to cut off power is recognized according to a change in the state of the electronic device 101 within the second period of time, the electronic device 101 may operate based on a preset option regarding whether to enter the shipping mode.

When a power key is input or an adapter is inserted after being set to the shipping mode, the electronic device 101 may control the switch 250, the switch 250 controlling a path to transmit power from the battery 189. The electronic device 101 may load the power meter data stored in memory 130 or 231.

When a power key is input or an adapter is inserted after being set to the shipping mode, the electronic apparatus 101 can cancel the shipping mode of the electronic apparatus 101 by turning on the switch 250. The power management module 188 may cancel the shipping mode of the electronic device 101 by causing the switch 250 to turn on when a power key is entered or the adapter 300 is inserted.

Referring to the description of fig. 3 provided above, the electronic device 101 may be set to a shipping mode after power is turned off. According to one embodiment, the electronic device 101 may be set to a shipping mode based on the voltage amplitude of the battery 189 after power is turned off. According to one embodiment, the electronic device 101 may be set to the shipping mode after a set first period of time has elapsed after the power is turned off.

The electronic apparatus 101 can stably secure a time to cut off the power of the electronic apparatus 101 while extending a standby time from a state where the power is cut off to overdischarge of the battery 189 by being set to a shipping mode based on the voltage amplitude of the battery 189 or the set first period of time. In the embodiment shown in fig. 3, by securing the time to cut off the power of the electronic device 101, it is possible to prevent an abnormality of the internal components of the electronic device 101 that may occur as the electronic device 101 enters the shipping mode before the power is completely cut off.

Fig. 4 is a flow chart of the operation of an electronic device (e.g., electronic device 101 of fig. 1) according to various embodiments.

Referring to fig. 4, in operation 301, the electronic device 101 in various embodiments may receive a user input to shut off power to the electronic device 101. For example, the user input to turn off power to the electronic device 101 may include a power key input of the electronic device 101 or an input through an interface displayed on a display module (e.g., display module 160 of fig. 1).

For example, in operation 302, the electronic device 101 may identify a voltage of a battery (e.g., battery 189 of fig. 1). The voltage of battery 189 identified by electronic device 101 in operation 302 may be the voltage of battery 189 when user input to turn off electronic device 101 is received. For example, a power management module (e.g., power management module 188 of fig. 1) may identify the voltage of battery 189, and processor 120 may identify the voltage of battery 189 from the power management module.

For example, in operation 303, the electronic device 101 may set a reference voltage based on the margin voltage and the voltage of the battery 189. The reference voltage may be a threshold value used to determine whether the electronic device 101 is set to a shipping mode by the power management module.

For example, the electronic device 101 may set the reference voltage by using an amplitude obtained by subtracting the margin voltage from the voltage of the identified battery 189. For example, the magnitude of the margin voltage may be set to a specified value.

For example, in operation 304, the electronic apparatus 101 may perform an operation to cut off power. For example, the electronic device 101 may terminate an OS or program run by a processor (e.g., the processor 120 of fig. 1) to shut off power. For example, when the electronic apparatus 101 performs an operation to cut off power, the power supply to a component of the electronic apparatus 101 (such as the processor 120) may be stopped.

For example, in operation 305, the electronic device 101 may monitor the voltage of the battery 189 after cutting off power. For example, the power management module may identify the voltage of battery 189 after cutting off power. Even after the power of the electronic device 101 is cut off, the voltage of the battery 189 may gradually drop due to leakage current.

For example, in operation 306, the electronic device 101 may determine whether the voltage of the battery 189 is less than or equal to a reference voltage. According to one embodiment, the electronic device 101 may determine whether the voltage of the battery 189 is less than or equal to the reference voltage at a predetermined period. For example, when the voltage of the battery 189 is less than or equal to the reference voltage in operation 306, the electronic device 101 may determine whether the time during which the voltage of the battery 189 is maintained at less than or equal to the reference voltage is greater than or equal to the anti-shake time in operation 307.

In operation 306 or 307, when the voltage of the battery 189 is greater than or equal to the reference voltage or the time during which the voltage of the battery 189 is maintained at less than or equal to the reference voltage is less than or equal to the anti-shake time, the electronic device 101 may monitor the voltage of the battery 189 according to operation 305. According to one embodiment, the electronic device 101 may monitor whether the voltage of the battery 189 is less than or equal to the reference voltage and whether the time during which the voltage of the battery 189 is maintained at less than or equal to the reference voltage is greater than the anti-shake time at a predetermined period.

For example, in operation 308, the electronic device 101 may store the power count in a memory (e.g., memory 130 or 231 of fig. 3). For example, the power meter data may include usage status information (e.g., capacity of battery 189, number of charge and discharge cycles, voltage, or temperature) or charge status information related to the charging of battery 189 (e.g., lifetime, overvoltage, low voltage, low current, overcurrent, overcharge, overdischarge, overheat, short circuit, or bulge).

For example, in operation 308, the MCU of the power management module (e.g., MCU 290 of fig. 3) may store the power count in a memory (e.g., memory 231 of fig. 3) of the power meter (e.g., power meter 230 of fig. 2). In another example, in operation 308, the MCU or the processor 120 of the power management module may store the power count in the memory.

For example, in operation 309, the electronic device 101 may set the electronic device 101 to a shipping mode. For example, in operation 310, the electronic device 101 may control the operation of a switch (e.g., the switch 250 of fig. 3) forming a path to transmit power from the battery 189. For example, the battery 189 may transmit power to components in the electronic device 101 such as: processor 120, ICs, display module (e.g., display module 160 of fig. 1), sound output module (e.g., sound output module 155 of fig. 1), communication module (e.g., communication module 190 of fig. 1), audio module (e.g., audio module 170 of fig. 1), sensor module (e.g., sensor module 176 of fig. 1), haptic module (e.g., haptic module 179 of fig. 1), and camera module (e.g., camera module 180 of fig. 1). For example, in operation 310, when a path through which power is transmitted from the battery 189 is blocked as the power management module turns off the switch, a path through which leakage current flows may be blocked.

For example, in operation 311, the electronic device 101 may identify whether a power key is entered or an adapter (e.g., adapter 300 of fig. 3) is inserted. For example, the power management module of the electronic device 101 may receive a signal when a power key is entered. When the power management module recognizes that the power key is input, the power management module may cancel the shipping mode of the electronic apparatus 101.

In another example, when the adapter is inserted in operation 311, the power management module may recognize that the adapter is inserted and the power management module may cancel the shipping mode of the electronic device 101.

For example, when a power key is input or an adapter is inserted in operation 311, the electronic device 101 may control the operation of the switch in operation 312. For example, the power management module of the electronic device 101 may control the operation of the switch so that a path may be formed for transmitting power from the battery 189 to components in the electronic device 101 such as: processor 120, IC, display module, sound output module, communication module, audio module, sensor module, haptic module, or camera module.

For example, in operation 313, the electronic device 101 may load power meter data from memory. The electronic device 101 may load the power meter data stored in the memory and the power meter may identify the loaded power meter data. When the electronic device 101 loads the power meter data stored in the memory, the power meter data can be prevented from being reset even when the electronic device 101 is set to the shipping mode and then the shipping mode is canceled.

Fig. 5 is a flow chart of the operation of an electronic device (e.g., electronic device 101 of fig. 1) according to various embodiments.

The embodiment shown in fig. 5 may represent an operational flow diagram when the electronic device 101 receives input from a user to set to a shipping mode.

Referring to fig. 5, in operation 401, the electronic device 101 in various embodiments may receive user input. For example, the user input may be an input to set a shipping mode. For example, input to set the electronic device 101 to the shipping mode may be received from a user through a user interface output on a display module (e.g., display module 160 of fig. 1) of the electronic device 101.

In another example, the electronic device 101 may include a separate input element for setting the electronic device 101 to a shipping mode. For example, a user may enter keys or buttons to set the electronic device 101 to a shipping mode.

For example, in operation 402, the electronic apparatus 101 may perform an operation of cutting off power. In operation 403, the electronic device 101 may store the power count in a memory (e.g., memory 130 or 231 of fig. 3). In operation 404, the electronic device 101 may set the electronic device 101 to a shipping mode. In operation 405, the electronic device 101 may control operation of a switch (e.g., the switch 250 of fig. 3) forming a path for transmitting power from a battery (e.g., the battery 189 of fig. 1). For example, the power management module may block the path for transmitting power from the battery 189 by opening the switch.

In operation 406, it may be identified whether a power key is entered or an adapter (e.g., adapter 300 of FIG. 3) is inserted. When a power key is input or an adapter is inserted in operation 406, the electronic device 101 may control the operation of the switch in operation 407. In operation 408, the electronic device 101 may load power meter data stored in memory.

Operations 402, 403, 404, 405, 406, 407, and 408 described above may be substantially the same as operations 304, 308, 309, 310, 311, 312, and 313 of fig. 4. Accordingly, even though descriptions are omitted for operations 402, 403, 404, 405, 406, 407, and 408, the descriptions provided with reference to operations 304, 308, 309, 310, 311, 312, and 313 of fig. 4 may be equally applied.

In an embodiment different from the embodiment shown in fig. 5, in operation 401, the electronic device 101 may identify the voltage of the battery 189 upon receiving a user input to set the electronic device 101 to a shipping mode. For example, in operation 404, the electronic device 101 may monitor the voltage of the battery 189 using a power management module (e.g., the power management module 188 of fig. 1) after cutting off power to the electronic device 101. For example, in operation 404, the electronic device 101 may set the electronic device 101 to the shipping mode by comparing the monitored voltage of the battery 189 to the voltage of the battery 189 when the user input is received.

For example, when the monitored voltage of the battery 189 has decreased by the set margin voltage from the voltage of the battery 189 when the user input is received, the electronic device 101 may set the electronic device 101 to the shipping mode.

For example, as shown in fig. 5, the margin voltage when the electronic device 101 receives user input from a user to set the electronic device 101 to the shipping mode may be different from the margin voltage used to set the reference voltage in the embodiment shown in fig. 4.

For example, in operation 404, the magnitude of the margin voltage may be set to be less than the margin voltage described with reference to fig. 4, e.g., 50mV. Even when an input to set the electronic device 101 to the shipping mode is received from the user, the time to shut off the power of the electronic device 101 can be ensured by setting the electronic device 101 to the shipping mode based on the small margin voltage.

In an embodiment different from the embodiment shown in fig. 5, the electronic device 101 may set the electronic device 101 to the shipping mode based on a change in the voltage of the battery 189 within a set period of time after the power is cut off in operation 404.

For example, after the power of the electronic device 101 is cut off, the voltage of the battery 189 may decrease due to leakage current. The voltage decrease amount of the battery 189 due to the leakage current may be significantly smaller than the voltage decrease amount of the battery 189 due to the operation of the electronic device 101. For example, the electronic device 101 may use the reduced voltage amplitude of the battery 189 over a set period of time to determine whether the power of the electronic device 101 is normally shut off.

For example, the battery 189 may decrease in voltage by less than or equal to 1mV in 24 hours from the operation of shutting off the power of the electronic device 101, and the electronic device 101 may determine that the power of the electronic device 101 is normally shut off.

Fig. 6 is a flow chart of the operation of an electronic device (e.g., electronic device 101 of fig. 1) in accordance with various embodiments.

Referring to fig. 6, the electronic device 101 in one embodiment may identify a signal to shut off power to the electronic device 101.

For example, in operation 510, the electronic device 101 may receive a user input to set a shipping mode. The user input received in operation 510 may represent a signal to shut off power.

For example, in operation 520, the electronic device 101 may determine a change in the state of the electronic device 101 within a set second period of time. When the state of the electronic device 101 is not changed within the set second period of time, the electronic device 101 may output a signal to cut off power.

For example, in the case of a screen touch input through a display module (e.g., display module 160 of fig. 1), a key input such as a power key or a volume adjustment key, a connection to a wired or wireless charger, an operating state of the electronic device 101, or an external environmental state collected by a sensor module (e.g., sensor module 176 of fig. 1), and a movement of the terminal (e.g., a movement of the terminal collected by a gyro sensor using sensor module 176), the electronic device 101 may determine that the state of the electronic device 101 has changed.

In operation 530, the electronic apparatus 101 may perform an operation of cutting off power. For example, when a user input is received in operation 510 or when the state of the electronic device 101 is not changed for a second period of time in operation 520, the electronic device 101 may perform an operation of cutting off power in operation 530. The electronic device 101 may terminate the running program, OS, etc., and may block power supplied to the elements included in the electronic device 101 (e.g., the processor 120, the memory 130, the display module 160, and the IC).

In operation 540, the electronic device 101 may time the set first period of time. The processor (e.g., processor 120 of fig. 1) may send a control signal to a power management module (e.g., power management module 188 of fig. 1). The power management module 188 may time the set first period based on the control signal. The electronic device 101 may determine the first period of time based on the voltage amplitude of the battery 189 upon identifying the signal to cut off power. For example, the processor 120 may determine the first period of time as being positively correlated to the voltage amplitude of the battery 189.

For example, before the operation of shutting off the power of operation 530 is completed, the processor 120 may determine the first period of time based on the voltage amplitude of the battery 189. For example, in operation 540, the power control module 270 of the power management module 188 may determine the first period of time based on the voltage magnitude of the battery 189.

In operation 550, the electronic device 101 may determine whether a power key is entered or an adapter is inserted within a first time period.

When the power key is not input or the adapter is not inserted for a first period of time in operation 550, the electronic device 101 may store the power count in a memory (e.g., memory 130 or 231 of fig. 3) in operation 560. The power meter data may include data regarding the status of battery 189.

In operation 570, the electronic device 101 may set the electronic device 101 to a shipping mode.

According to the embodiment shown in fig. 6, the electronic device 101 can minimize discharge of the battery 189 due to leakage current, and can extend standby time in a power-off state.

For example, the total capacity of the battery 189 may be about 5000mAh, the voltage of the battery may be about 4.0V when the power is cut off, the remaining capacity of the battery 189 may be about 3000mAh when the power is cut off, and the magnitude of the leakage current in the power-off state may be about 300uA. After the electronic device 101 is set to the shipping mode, the magnitude of the leakage current may be about 30uA. After the voltage of the battery 189 reaches the V1 voltage (e.g., 2.6V), the electronic device 101 may be set to the shipping mode, and after the electronic device 101 is set to the shipping mode, the voltage of the battery 189 may reach the V2 voltage (e.g., 1.5V), at which the battery 189 is overdischarged. In the above example, the standby time taken for the voltage of the battery 189 to reach the V1 voltage may be about 13.9 months (3000 mAh/300 ua=10000 h), and the standby time taken for reaching the V2 voltage after reaching the V1 voltage may be about 1.38 months (30 mAh/30 ua=1000 h). When the voltage of the battery 189 is about 4.0V when power is cut off, the total standby time taken to reach the V2 voltage may be about 15.28 months.

The V1 voltage may be a reference voltage to determine whether to enter a shipping mode to prevent overdischarge of the battery 189. The V2 voltage may be a voltage at which the battery 189 is overdischarged.

According to the embodiment shown in fig. 6, after the power of the electronic device 101 is cut off, the time required for the voltage of the battery 189 to reach the V1 voltage or the V2 voltage is prolonged.

For example, the total capacity of the battery 189 may be about 5000mAh, the voltage of the battery may be about 4.0V when power is cut off, the remaining capacity of the battery 189 may be about 3000mAh when power is cut off, and the magnitude of the leakage current after the electronic device 101 is set to the shipping mode may be about 30uA. When the electronic device 101 is set to the shipping mode after the power of the electronic device 101 is turned off and a set first period of time (e.g., 24 hours, 48 hours, etc.) has elapsed, the time taken for the voltage of the battery 189 (which is about 4.0V) to reach the V1 voltage may be about 139 months (3000 mAh/30 ua=100000 h). The electronic device 101 may set the electronic device 101 to the shipping mode when a set first period of time has elapsed after the power is cut off, and thus, the standby time taken for the voltage of the battery 189 to reach the V1 voltage may be prolonged.
