Description

Electronic device, method and non-transitory storage medium for managing battery deterioration

[0001] Various embodiments of the present disclosure relate to electronic devices, methods, and non-transitory storage media for managing the degradation of a battery.

[0002] With the advancement of digital technology, electronic devices are now available in various forms, such as smartphones, tablet personal computers (PCs), and personal digital assistants (PDAs). Electronic devices are also being developed into wearable devices to enhance portability and accessibility.

[0003] The variety of services and additional features offered by electronic devices is steadily expanding and diversifying. Electronic devices are continually being developed to enhance their utility and satisfy the diverse needs of users.

[0004] As electronic devices evolve into diverse forms, they can connect to various external electronic devices, providing functions or information not available on their own. Furthermore, these electronic devices can enable external electronic devices to perform some of their functions or receive various information through other networks.

[0005] Compensation for battery degradation in electronic devices containing small batteries compensates for battery degradation over the charge / discharge cycles used by the battery.

[0006] At the point when the battery of an electronic device starts charging, the charge / discharge cycle of the battery is checked and a long-life algorithm operation is performed based on this. The long-life algorithm can set a margin for the charging-related parameters according to the predicted battery deterioration by changing the full charge voltage, supplementary voltage, and OCV (open circuit voltage) tables.

[0007] Electronic devices can only reflect the lifespan of charge and discharge cycles of small-capacity, high-resistance coin batteries, and do not reflect the lifespan of storage environments (temperature, state of charge (SOC), etc.) that have a high impact. Generally, the deterioration and lifespan of the battery can be measured and compensated for through FuelGuage monitoring. However, while large-capacity batteries can be monitored in real time by FuelGuageIC, electronic devices with small-capacity (e.g., less than about 60mAh) batteries (e.g., earbuds) may have a difficult time monitoring the battery in real time because the total capacity is small and the usage time is significantly reduced when FuelGuageIC performs real-time monitoring.

[0008] Battery deterioration can be divided into deterioration due to the charge / discharge cycles used and the storage environment. Electronic devices calculate the SOC only when the battery is powered on and compensate for the charge / discharge cycles used. However, a gap occurs between the actual battery deterioration and the number of charge / discharge cycles. This can lead to increased battery resistance, preventing the battery from reaching its full charge voltage and potentially damaging the battery.

[0009] According to one embodiment of the present disclosure, an electronic device is provided, a method, and a non-transitory storage medium for managing battery deterioration in an electronic device having a small-capacity battery that is difficult to monitor in real time (e.g., earbuds or smart rings).

[0010] According to one embodiment of the present disclosure, an electronic device includes a battery, a communication circuit, at least one processor, and a memory storing instructions.

[0011] According to one embodiment, the instructions, when individually or collectively executed by at least one processor of the electronic device, cause the electronic device to connect to a first external electronic device that provides power through the communication circuit.

[0012] According to one embodiment, the instructions cause the electronic device to obtain charging start state information and store the charging start state information when charging of the battery begins with power applied from the first external electronic device.

[0013] According to one embodiment, the instructions cause the electronic device to obtain charging termination status information based on the termination of charging of the battery, and to store the charging termination status information.

[0014] According to one embodiment, the instructions identify a battery state based on the charging start state information and the charging end state information, and perform a battery degradation measurement operation based on the identified battery state information.

[0015] According to one embodiment, the instructions cause a compensation operation to be applied during charging of the battery based on information obtained by the battery degradation measurement operation.

[0016] According to one embodiment, a method of operating an electronic device includes obtaining connection information indicating a connection with a first external electronic device that provides power to charge the battery.

[0017] According to one embodiment, the operating method includes an operation of acquiring charging start status information and storing the charging start information in a memory of the electronic device when charging of the battery starts with power applied from the first external electronic device.

[0018] According to one embodiment, the operating method includes an operation of obtaining charging termination status information based on the termination of charging of the battery, and storing the charging termination status in the memory.

[0019] According to one embodiment, the operating method includes an operation of identifying a battery state based on the charging start state information and the charging end state information, and an operation of measuring a battery deterioration level based on the identified battery state information.

[0020] According to one embodiment, the operating method includes an operation of performing a compensation operation for compensating for deterioration of the battery corresponding to each of the deterioration levels to be applied during charging of the battery, based on information acquired by the battery deterioration measurement operation.

[0021] According to one embodiment, a non-transitory storage medium storing one or more programs includes instructions that, when executed by at least one processor of an electronic device, cause the electronic device to perform an operation of: obtaining connection information indicating a connection with a first external electronic device that provides power to charge the battery; obtaining charging start state information when charging of the battery starts with power supplied from the first external electronic device, and storing the charging start information in a memory of the electronic device; obtaining charging end state information and storing the charging end state information in the memory based on the termination of charging of the battery; identifying a battery state based on the charging start state information and the charging end state information; performing a battery deterioration measurement operation based on the identified battery state information; and performing a compensation operation to be applied during charging of the battery based on information obtained by the battery deterioration measurement operation.

For example, if the electronic device (101) includes a main processor (121) and a secondary processor (123), the secondary processor (123) may be configured to use less power than the main processor (121) or to be specialized for a specified function. The secondary processor (123) may be implemented separately from the main processor (121) or as a part thereof.

[0034] The auxiliary processor (123) may control at least a portion of functions or states associated with at least one component (e.g., a display module (160), a sensor module (176), or a communication module (190)) of the electronic device (101), for example, on behalf of the main processor (121) while the main processor (121) is in an inactive (e.g., sleep) state, or together with the main processor (121) while the main processor (121) is in an active (e.g., application execution) state. In one embodiment, the auxiliary processor (123) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (180) or a communication module (190)).

The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

According to one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least a part of the service.

[0063] According to one embodiment, the electronic devices (201a, 201b) may be arranged so that the acoustic components (e.g., audio modules) and electronic components (e.g., processors) inside the electronic devices (201a, 201b) enhance the acoustic performance.

According to one embodiment, each of the first electronic device (201a) and the second electronic device (201b) may convert data received from the second external electronic device (101) into sound and output the converted sound (e.g., audio, music, ambient sound, notification sound, or phone sound) through a speaker. Each of the first electronic device (201a) and the second electronic device (201b) may acquire external sound (e.g., a user's voice or ambient sound) through at least one microphone and transmit data corresponding to the acquired sound to the second external electronic device (101).

[0064] According to one embodiment, the electronic devices (201a, 201b) may be wirelessly connected to the second external electronic device (101). For example, the electronic devices (201a, 201b) may communicate with the second external electronic device (101) via a network (e.g., a short-range wireless communication network or a long-range wireless communication network). The network may include, but is not limited to, a mobile or cellular communication network, a local area network (LAN) (e.g., Bluetooth communication, Bluetooth Low Energy communication), a wireless local area network (WLAN), a wide area network (WAN), the Internet, or a small area network (SAN).

[0066] FIG. 3 is a block diagram showing a configuration of an electronic device according to one embodiment.

[0067] Referring to FIG. 3, an electronic device (201) (e.g., a first electronic device (201a) or a second electronic device (201b)) according to one embodiment includes a processor (310) (e.g., a processor (120) of FIG. 1), a power management module (320) (e.g., a power management module (188) of FIG. 1), a battery (321) (e.g., a battery (189) of FIG. 1), a memory (330) (e.g., a memory (130) of FIG. 1), a communication module (340) (e.g., a communication module (190) of FIG. 1), at least one microphone (350) (e.g., an input module (150) of FIG. 1), a sensor module (360) including at least one sensor (e.g., a sensor module (176) of FIG. 1), a speaker (370) (e.g., an audio output module (155) of FIG. 1) and / or an input module (380) (e.g., an input module (380) of FIG. 1) It may include a module (150). The term “module” of the components described in FIG. 3 may be replaced with “circuit”.

[0068] According to one embodiment, a processor (310) may be electrically or operatively connected to a power management module (320), a battery (321), a memory (330), a communication module (340), a sensor module (360) including at least one microphone (350), at least one sensor, a speaker (370), and / or an input module (380), and may perform overall control operations of the electronic device (201).

[0069] According to one embodiment, the processor (310) may control a battery (321) that provides power to drive the electronic device (201). The processor (310) may manage charging and discharging of the battery (321) through a power management module (320). According to one embodiment, the processor (310) may include a voice processing circuit, and may control the voice processing circuit to process audio data received from a second external electronic device (101) and output an audio signal (e.g., an acoustic signal).

[0070] According to one embodiment, the processor (310) can identify that the electronic device (201) is accommodated in the accommodation space (211) of the first external electronic device (203) and connected to the first external electronic device (203), and can charge the battery (321) with power supplied from the battery (232) of the first external electronic device (203). Without being limited thereto, when an external power source (e.g., TA, wireless charger, or D2D) is supplied to the first external electronic device (203), the electronic device (201) can receive the external power source through the first external electronic device (203) and charge the battery (321). According to one embodiment, the processor (310) can monitor the charging voltage level of the battery (321) to determine whether it is fully charged, and if the battery (321) is fully charged, can terminate charging. The processor (310) can transmit a control signal to the first external electronic device (203) to terminate charging via the communication module (340). The processor (310) monitors the charging voltage after the battery (321) is fully charged to determine whether charging is required, and when the monitored battery voltage level reaches the charging voltage value, the processor (310) can control the battery (321) to be charged from the charging start time to the full charging time. The processor (310) can transmit a control signal to the first external electronic device (203) to initiate charging via the communication module (340).

[0071] According to one embodiment, when the processor (310) starts charging the battery (321) with power supplied from the first external electronic device (203) or an external power source supplied to the first external electronic device (203), the processor (310) may acquire charging start state information and store the acquired charging start state information in the memory (330). Here, the charging start state information may include at least one of voltage, current, state of charge (SOC), or temperature at the time of charging start of the battery (321). The processor (310) may, based on the fact that the electronic device (201) is accommodated in the accommodation space (211) inside the first housing (210) of the first external electronic device (203) and the second housing (220) is closed, when charging the battery (321) by the first external electronic device (203), connect to the second external electronic device (101) using a wireless communication method (e.g., Bluetooth communication) after the charging of the battery (321) is terminated (e.g., stopped or fully charged) without performing wireless communication with the second external electronic device (101).

[0072] According to one embodiment, the processor (310) may obtain charging termination status information based on whether charging of the battery (321) has been terminated (e.g., charging stopped or fully charged), and store the obtained charging termination status information in the memory (330). Here, the charging termination status information may include at least one of voltage, current, state of charge (SOC), or temperature at the time of charging termination of the battery (321).

[0073] According to one embodiment, the processor (310) may compare the charging start state information and the charging end state information stored in the memory (330) after the charging of the battery (321) is terminated to determine the battery deterioration through a battery deterioration measurement operation (e.g., a battery deterioration algorithm). According to one embodiment, the processor (310) may compare the charging start state information and the charging end state information stored in the memory (330) after the charging of the battery (321) is terminated to identify the battery state (e.g., a normal state, a risk of battery short circuit, or a reduction in lifespan), and may set battery state information for the identified battery state (e.g., current charge capacity information, a deterioration level value based on charge capacity, or notification information for notifying the risk of battery short circuit or a reduction in lifespan). Here, the processor (310) can set notification information using, for example, charge capacity information or a deterioration level value, and control the communication module (340) to transmit the set notification information to the first external electronic device (203) and / or the second external electronic device (101) by including it in the battery status information or separately. As another example, the second external electronic device (101) can set notification information based on the received battery status information and output (or display) the set notification information. The processor (310) can perform a deterioration level measurement operation of the battery (321) when the electronic device (201) is accommodated in the accommodation space (211) inside the first housing (210) of the first external electronic device (203) and the second housing (220) is closed. The processor (310) can identify that the user is using the electronic device (201) when the electronic device (201) is accommodated in the accommodation space (211) inside the first housing (210) of the first external electronic device (203) and the second housing (220) is in an open state, and can stop the deterioration measurement operation of the battery (321) as the power supply from the first external electronic device (203) is cut off.When some functions of the electronic device (201) are in an operating (in use) state, battery discharge may occur due to some of the functions being used, and thus accurate deterioration measurement may be difficult by constant current discharge operation. Therefore, the electronic device (201) may stop the deterioration measurement operation of the battery (321) in the open state of the first external electronic device (203). According to one embodiment, the processor (310) may measure the actual deterioration of the battery (321) by using the constant current discharge operation in a specific section after the battery (321) is fully charged in order to set compensation operations. The processor (310) determines whether the battery (3221) is deteriorated (e.g., aging) based on the charging start status information and the charging end status information, and if the degree of deterioration is within a normal range (e.g., a range that is not determined to be a time for battery replacement due to battery damage or reduced battery life), the processor (310) can measure the actual degree of deterioration of the battery (321) by the constant current function by activating (turning on) a constant current function (e.g., LED (light emitting diode)) for a specified time (e.g., 5 seconds) using a constant current discharge operation.

[0074] According to one embodiment, when the processor (310) performs a battery degradation measurement operation (e.g., before or when performing a constant current discharge operation after a full charge), the processor (310) may compare a charge start temperature value included in charge start state information with a charge end temperature value included in the charge end state information to obtain a temperature change value, and when a state in which the temperature change value is greater than or equal to a first threshold value (e.g., a first state) occurs a specified number of times (e.g., three times), the processor (310) may control the communication module (340) to lower the full charge voltage of the battery (321) to a specified value (-2.0 V) and transmit battery state information for notifying a risk of damage to the battery (321) to at least one of the first external electronic device (101) and the second external electronic device (203). Here, when the battery (321) is in a damaged state, the processor (310) may lower the full charge voltage to a specified value to reduce charging in a CV (constant voltage) section in order to protect the battery (321). According to one embodiment, if the temperature change value is greater than or equal to a first threshold value and occurs less than a specified number of times, the processor (310) may return to a previously set value. According to one embodiment, if the temperature change value is greater than or equal to the first threshold value and occurs less than a specified number of times, the processor (310) may obtain a voltage change value by comparing a charge start voltage value included in charge start state information with a charge end voltage value included in charge end state information, and if the voltage change value is greater than or equal to a second threshold value (e.g., a second state) and occurs less than a specified number of times (e.g., 3 times), the processor may measure the deterioration of the battery (321) through a constant current (CC) discharge operation.When a state in which the voltage change amount value is greater than or equal to a second threshold value occurs a specified number of times, the processor (310) can control the communication module (340) to store information related to the reduction in battery life (e.g., NV value) and transmit battery status information for notifying the risk of damage to the battery (321) or a battery replacement guide to at least one of the first external electronic device (101) or the second external electronic device (203).

[0075] According to one embodiment, the processor (310) may set compensation operations for battery degradation compensation according to degradation levels acquired by the battery degradation measurement operation. The processor (310) may perform compensation for resistance and voltage drop of the battery (321) according to the compensation operations set according to the acquired degradation levels. The processor (310) may set a first compensation operation without compensation information based on the degradation level being a first degradation level. The processor (320) may set a second compensation operation including first compensation information based on the degradation level being a second degradation level (e.g., a level at which there is no problem in using the electronic device (201) with a set full charge voltage). Here, the first compensation information may include a first full charge condition margin value (e.g., +30 mV). According to one embodiment, the processor (310) may set a third compensation operation including second compensation information based on whether the degradation level is a third degradation level (e.g., a level that may cause damage to the battery). Here, the second compensation information may include a second full charge condition margin value (e.g., +50 mV) and a first voltage value for a full charge voltage reduction (e.g., -0.1 V). The full charge voltage may be specified to a different value for each battery compensation charge level.

[0076] According to one embodiment, the processor (310) may perform a compensation operation (e.g., a plurality of set compensation operations) of the battery (321) using a compensation algorithm (e.g., a long-life algorithm) that applies compensation operations set for each of a plurality of deterioration levels. For example, the processor (310) may determine a deterioration level based on state of charge information (SOC) measured during charging or recharging of the battery (321), and if the determined deterioration level is a first deterioration level, the first compensation operation may be applied, and since the first compensation operation does not include a compensation value, if it is the first deterioration level, the deterioration (e.g., capacity) of the battery (321) may not be compensated. For example, if the confirmed deterioration level is a second deterioration level (e.g., a level at which there is no problem in using the electronic device (201) with the set full charge voltage), the deterioration (e.g., capacity) of the battery (321) can be compensated for by applying the first full charge condition margin value (e.g., +30 mV) included in the second compensation operation. For example, if the confirmed deterioration level is a third deterioration level (e.g., a level at which damage is caused to the battery), the second full charge condition margin value (e.g., +50 mV) included in the third compensation operation can be applied and the full charge voltage can be lowered to the first voltage value (e.g., -0.1 V) to compensate for the deterioration (e.g., capacity) of the battery (321).

[0077] According to one embodiment, the power management module (320) can efficiently manage and optimize the power usage of the battery (321) within the electronic device (201). According to one embodiment, the power management module (320) can adjust the power supplied to the processor (310) based on a signal provided according to a load to be processed by the processor (310) or adjust the power provided to each component (e.g., memory, communication module, input module, and / or sensor) other than the processor (310). According to one embodiment, the power management module (320) can include a battery charging module. According to one embodiment, the power management module (320) can receive power wired or wirelessly from a first external electronic device (203), which is an external power supply device, to charge the battery (321). According to one embodiment, the battery (321) can be charged with power supplied from the first external electronic device (203). As the battery (321) decreases in voltage (capacity) over time due to natural discharge, when the battery (321) drops to the charging voltage, it can be charged to the full charge voltage with power supplied from the first external electronic device (203).

[0078] According to one embodiment, the memory (330) may store various data and / or information used by at least one component of the electronic device (201) (e.g., a power management module (320), a battery (321), a memory (330), a communication module (340), at least one microphone (350), a sensor module (360) including at least one sensor, a speaker (370), and / or an input module (380)). The data may include, for example, software (e.g., a program) and input data or output data for commands related thereto. For example, the memory (330) may store instructions for performing operations of the electronic device (201) (or the processor (310)). According to one embodiment, the memory (330) may store information related to charging and replenishing of the battery (321). The memory (330) may store charging start state information and charging end state information of the battery (321), and may store information related to set compensation operations of a compensation algorithm.

[0079] According to one embodiment, the electronic device (201) may provide a user interface for a function of receiving audio data from a second external electronic device (101) or a function of transmitting audio data to the second external electronic device (101). For example, the user interface may include a light-emitting means (e.g., a constant current means or function) such as a light emitting diode (LED). For example, the light-emitting means may be controlled to emit a color corresponding to charging or completion of charging. For example, when the electronic device (201) is connected to the second external electronic device (101), the light-emitting means may be controlled by the processor (310) to emit light in a specific color.

[0080] According to one embodiment, at least one microphone (350) can acquire a sound signal when it is on (e.g., activated or operating). When the electronic device (201) includes a plurality of microphones, at least one of the plurality of microphones (e.g., an inner mic) can be placed near the inside of the ear when the electronic device (201) is inserted into the ear, and at least one other microphone can be placed outside the ear when the electronic device (201) is worn on the user's ear. At least one microphone (350) can be turned on (e.g., activated or operating) or off (e.g., deactivated or not operating) under the control of the processor (310). Although the electronic device (201) is illustrated as including at least one microphone (350) in FIG. 3 , the technical idea of ​​the present disclosure may not be limited thereto. For example, the number of microphones may be plural, such as two, three, or more than three.

[0081] A sensor module (360) according to one embodiment may include at least one sensor capable of measuring or detecting changes in the surrounding environment (e.g., vibration, movement, and / or sound). According to one embodiment, the sensor module (360) may include a voice pick-up (VPU) sensor. For example, the VPU sensor may include a multi-axis acceleration sensor (e.g., a three-axis acceleration sensor, a six-axis acceleration sensor, or another multi-axis acceleration sensor), and may detect a signal (e.g., a vibration signal, a movement signal, or a sound signal) transmitted through at least a part of the user's body for each axis. For example, when a user speaks, vibration of the user's vocal cords may be detected by the multi-axis acceleration sensor, and at least some of the plurality of sounds associated with the voice signal may be acquired as signals. According to one embodiment, the multi-axis acceleration sensor may be controlled by the processor (310) so that at least some of the plurality of axes are selectively activated or operated (e.g., turned on). The technical idea of ​​the present disclosure may not be limited thereto and may further include other sensors related to audio signal processing.

[0082] According to one embodiment, the speaker (370) can output an audio signal (e.g., a sound signal) based on the control of the processor (310).

[0083] An input module (380) according to one embodiment may be configured to generate various input signals required for operation (or operation control) of the electronic device (201). For example, the input module (380) may include a touchpad, a touch panel, or a button. The touchpad may recognize a touch input in at least one of, for example, an electrostatic, a pressure-sensitive, an infrared, or an ultrasonic manner. If an electrostatic touchpad is provided, physical contact or proximity recognition may be possible. The touchpad may further include a tactile layer. A touchpad including a tactile layer may provide a tactile response to a user. The button may include, for example, a physical button and / or an optical key. For example, the input module (380) may generate an input signal according to a user input and transmit the input signal to the processor (310). For example, the user input may be an input associated with a function of entering a call state, terminating a call state, adjusting the volume, and / or muting the device.

[0084] FIG. 4 is a graph related to battery charging in an electronic device according to one embodiment.

[0085] In one embodiment, the battery (321) of the electronic device (201) may have a battery capacity characteristic that decreases over time. For example, the battery capacity characteristic may drop (e.g., become lower than about 4.3 V to about 4.4 V) at a full charge voltage (e.g., about 4.3 V to about 4.4 V) and a recharge voltage (e.g., about 4.30 V) set for the battery (321) of the electronic device (201).

[0086] Referring to FIG. 4, according to one embodiment, the processor (310) may monitor a battery voltage (e.g., a first graph (410)) for charging a battery (321) in a charge / discharge cycle (e.g., cc1, cv1, cc2, and cv2 sections; t1 to t2). Here, the charge / discharge cycle may be a time section (e.g., a charging section) from a charging start time (t1) of the battery (321) to a full charge time (t2) of a full charge voltage (e.g., about 4.3 V to about 4.4 V). Here, the second graph (420) of FIG. 4 may represent a graph (e.g., CC (constant current) - CV (constant voltage)) representing a battery current value according to a battery charging operation during the charge / discharge cycle (t1 to t2). Here, the t1-t2 section illustrated in FIG. 4 may represent a battery charging section of 0% to 100%. According to one embodiment, the processor (310) may perform an actual battery deterioration measurement operation (e.g., constant current discharge operation) during the section t3 to t4 (e.g., measurement section) when the electronic device (201) is not used while the electronic device is accommodated in the first external electronic device (203) and the first external electronic device (203) is closed after a full charge (time point t2). When a discharge current flows in the section t2 to t4 shown in FIG. 4, a voltage drop may occur. In the first graph (410), the upper solid line is taken as a reference for a fresh cell with almost no deterioration, and the lower solid line is a cell in which the internal resistance increases so that the voltage drop is higher even at the same discharge current. The processor (310) may check the degree of deterioration as a delta value of the difference between the deteriorated battery Vdrop and the fresh cell Vdrop.

[0087] An electronic device (201) according to an embodiment may implement a software module (e.g., a program (140) of FIG. 1) for battery charge management. A memory (330) of the electronic device (201) may store commands (e.g., instructions) to implement the software module illustrated in FIG. 2. At least one processor (321) may execute the commands stored in the memory (330) to implement the software module and control hardware associated with the function of the software module. The software module of the electronic device (201) according to an embodiment may be configured to include a kernel (or HAL), a framework (e.g., a middleware (144) of FIG. 1), and an application (e.g., an application (146) of FIG. 1).

[0088] As such, in one embodiment, the main components of the electronic device have been described through the electronic device (201) of FIG. 3. However, in various embodiments, not all of the components illustrated through FIG. 3 are essential components, and the electronic device (201) may be implemented with more components than the illustrated components, or with fewer components. In addition, the locations of the main components of the electronic device (201) described above through FIG. 3 may be changed according to various embodiments.

[0107] According to one embodiment, the instructions may cause the electronic device to not perform wireless communication with a second external electronic device (e.g., the electronic device (101) of FIG. 1 and the second external electronic device (101) of FIG. 2C) when charging the battery by the first external electronic device, based on the electronic device being accommodated in an accommodation space within a first housing of the first external electronic device and the second housing being closed.

[0108] Figure 5 is a flowchart illustrating an example of an operating method in an electronic device according to one embodiment. In the following embodiments, the operations may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0109] Referring to FIG. 5, an electronic device according to an embodiment (e.g., the electronic device (201) of FIGS. 2A, 2C, and 3) may, in operation 501, connect to a first external electronic device (e.g., the first external electronic device (203) of FIGS. 2A and 2B) via a wireless communication method (e.g., a Bluetooth communication method). The electronic device may be accommodated in the first external electronic device, which is a receiving device such as a cradle, for charging and / or storage.

[0110] In operation 503, the electronic device may start charging the battery, acquire charging start state information, and store the acquired charging start information in a memory (e.g., memory (330) of FIG. 3). Here, the charging start state information may include at least one of a voltage, a current, an SOC, or a temperature of the battery. When the electronic device is accommodated in the first external electronic device, when one side of the second housing (e.g., the second housing (220) of FIG. 2A) of the first external electronic device is rotated in a direction closer to one side of the first housing (e.g., the first housing (210) of FIG. 2A) and thus the first external electronic device is in a closed state (e.g., a shielded state), the electronic device may perform charging, and when one side of the second housing is rotated in a direction away from one side of the first housing and thus the first external electronic device is in an open state, the electronic device may not perform charging.

[0111] In operation 505, the electronic device can perform battery charging.

[0112] In operation 507, the electronic device may acquire charging termination status information based on whether battery charging has been terminated (e.g., stopped or fully charged), and store the acquired charging termination information in memory. Here, the charging termination status information may include at least one of the voltage, current, SOC, or temperature of the battery.

[0113] In operation 509, the electronic device may perform a deterioration measurement operation to check the battery deterioration based on the charging start state information and the charging end state information stored in the memory. According to one embodiment, when performing the deterioration measurement operation, the electronic device may identify a battery state and transmit battery state information related to the identified battery state to a first external electronic device or a second external electronic device (e.g., the electronic device (101) of FIG. 1 and the electronic device (101) of FIG. 2C). The first external electronic device or the second external electronic device may display set notification information on a display based on the received battery state information. The electronic device may be installed in the first external electronic device and wake up at a time of non-use after a full charge or at a specific period (e.g., time t3-t4 of FIG. 4) to measure the deterioration for a specified period (e.g., about 5 to 10 seconds) using a deterioration measurement algorithm.

[0114] In operation 511, the electronic device can set compensation operations of the compensation algorithm according to the identified deterioration level. The electronic device can compensate for the charging table using the compensation algorithm that applies the set compensation operations, and perform compensation operations for battery protection and capacity (e.g., voltage) compensation.

[0115] Figure 6 is a diagram illustrating an example of an operating method in an electronic device according to one embodiment. In the following embodiments, the operations may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0116] Referring to FIG. 6, an electronic device (e.g., the electronic device (201) of FIGS. 2A, 2C, and 3) according to an embodiment may, in operation 601, start charging a battery, acquire charging start status information, and store the acquired charging start information in a memory (e.g., the memory (330) of FIG. 3). Here, the charging start status information may include at least one of voltage, current, SOC, or temperature of a battery (e.g., the battery (321) of FIG. 3).

[0117] In operation 603, the electronic device can identify that battery charging has ended (e.g., stopped or fully charged), and in operation 605, can obtain charging end status information and store the obtained charging end information in memory. Here, the charging end status information can include at least one of a voltage, a current, a SOC, or a temperature of the battery. The electronic device can store a voltage before the charger is turned off (e.g., about 4.13 V) and a voltage after the charger is turned off (e.g., about 4.07 V) in the memory.

[0118] In operation 607, the electronic device can determine whether the first external electronic device is in a closed state (e.g., a shielded state) by rotating one side of the second housing (e.g., the second housing (220) of FIG. 2A) of the first external electronic device (e.g., the first external electronic device (203) of FIGS. 2A and 2B) toward and closing one side of the first housing (e.g., the first housing (210) of FIG. 2A)). If the determination result is in a closed state, the electronic device performs operation 609. Otherwise, if the first external electronic device is in an open state by rotating one side of the second housing away from and opening one side of the first housing (e.g., the first housing (210) of FIG. 2A), the electronic device can terminate the operation without performing the battery deterioration measurement operation.

[0119] In operation 609, the electronic device can determine whether the battery condition is within the normal range according to the degree of deterioration based on the charging start state information and charging end state information stored in the memory after the battery charging is completed. If the battery condition is determined to be outside the normal range, the electronic device can perform operation 611, and if the battery condition is within the normal range, the electronic device can perform operation 613.

[0120] In operation 611, the electronic device may transmit battery status information for notifying a risk of battery damage (e.g., defect or breakage) to at least one of the first external electronic device or the second external electronic device (e.g., the electronic device (101) of FIG. 1 or the second external electronic device (101) of FIG. 2C). According to one embodiment, the electronic device may compare a charging start temperature value included in the charging start status information with a charging end temperature value included in the charging end status information to obtain a temperature change value (e.g., a delta value between a temperature value at the start of charging and a temperature value at the end of CC1 (e.g., a point when the temperature is the highest during charging)), and when a state in which the temperature change value is greater than or equal to a first threshold value (e.g., a first state) occurs a specified number of times (e.g., three times), the electronic device may determine that the state of the battery is outside the normal range (e.g., an abnormal state of the battery due to damage or reduced lifespan), lower the full charge voltage of the battery (321) to a specified value (e.g., about -0.2 V), and transmit the battery status information. When the state in which the temperature change value is greater than or equal to a first threshold value occurs less than a specified number of times (e.g., three times), the electronic device compares the charge start voltage value included in the charge start status information with the charge end voltage value included in the charge end status information to obtain a voltage change value (e.g., a delta (△) value of the voltage values ​​before and after full charging), and when the state in which the voltage change value is greater than or equal to the first threshold value occurs less than a specified number of times (e.g., three times), the electronic device can identify that the battery life has been reduced and transmit battery status information.

[0121] In operation 613, the electronic device can measure the actual deterioration degree of the battery through a constant current discharge operation based on the battery condition being within a normal range. Here, the deterioration degree measurement can be performed once or twice or more. If the state in which the temperature change value is greater than or equal to a first threshold value (e.g., the first state) occurs less than a specified number of times, and if the state in which the voltage change value is greater than or equal to a second threshold value (e.g., the second state) occurs less than a specified number of times, the electronic device can measure the actual deterioration degree of the battery through a constant current discharge operation (e.g., the constant current discharge operation in the t3-t4 section (measurement section) of FIG. 4). If the degree of deterioration is within a normal range (e.g., a range in which the battery replacement time due to battery damage or reduced battery life is not confirmed), the electronic device can activate (turn on) a constant current function (e.g., an LED) for a specified time (e.g., about 5 seconds) using the constant current discharge operation to measure the actual deterioration degree of the battery by the constant current function. Electronic devices can determine actual deterioration by checking current consumption within a normal range through constant current discharge operation. Since accurate measurement of constant current discharge operation is difficult during battery charging due to the operation of other specific functions, constant current discharge operation can be performed after battery charging is complete and when the device is not in use.

[0122] In operation 615, the electronic device may set compensation operations for battery degradation compensation corresponding to each of the degradation levels acquired by the battery degradation measurement operation. The processor (310) may perform compensation for the resistance and voltage drop of the battery (321) for each of the set compensation operations corresponding to each of the acquired degradation levels. The processor (310) may set a first compensation operation without compensation information based on the degradation level being a first degradation level. The processor (320) may set a second compensation operation including first compensation information based on the degradation level being a second degradation level (e.g., a level at which there is no problem in using the electronic device (201) with a set full charge voltage). Here, the first compensation information may include a first full charge condition margin value (e.g., approximately +30 mV). The processor (310) may set a third compensation operation including second compensation information based on whether the degradation level is a third degradation level (e.g., a level that may cause damage to the battery). Here, the second compensation information may include a second full charge condition margin value (e.g., approximately +50 mV) and a first voltage value for a full charge voltage reduction (e.g., approximately -0.1 V).

[0123] According to one embodiment, the electronic device may perform a compensation operation of the battery using a compensation algorithm (e.g., a long-life algorithm) that applies set compensation operations. For example, the electronic device may determine a deterioration level based on charge state information measured during charging or recharging of the battery, and if the determined deterioration level is a first deterioration level, the electronic device may apply a first compensation operation. Since the first compensation operation does not include a compensation value, if it is the first deterioration level, the electronic device may not compensate for the deterioration (e.g., capacity) of the battery. For example, if the determined deterioration level is a second deterioration level, the electronic device may compensate for the deterioration (e.g., capacity) of the battery (321) by applying a first full charge condition margin value (e.g., +30 mV) included in the second compensation operation. For example, if the identified degradation level is a third degradation level, the electronic device may apply a second full charge condition margin value (e.g., +50 mV) included in the third compensation operation and lower the full charge voltage to a first voltage value (e.g., -0.1 V) to compensate for the degradation (e.g., capacity) of the battery (321).

[0124] Figure 7 is a diagram illustrating an example of an operating method of an electronic device and external electronic devices according to one embodiment. In the following embodiments, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel.

[0125] Referring to FIG. 7, an electronic device according to an embodiment (e.g., the electronic device (201) of FIGS. 2A, 2C, and 3) may be accommodated in a first external electronic device (203) (e.g., the first external electronic device (203) of FIGS. 2A and 2B) in operation 701 and may be connected to the first external electronic device (203) via a wireless communication method. In operation 702, the first external electronic device (203) may apply power to the electronic device (201). At this time, the first external electronic device (203) may accommodate the electronic device (201) and may be in a closed state.

[0126] In operation 703, the electronic device (201) can start charging the battery with power applied from the first external electronic device (203) and store charging start status information acquired at the start time in memory.

[0127] In operation 705, the electronic device (201) can confirm the end of battery charging, and in operation 707, when battery charging is ended, can store charging end status information.

[0128] In operation 709, the electronic device (201) may transmit charging end state information after performing a communication connection with the second external electronic device (101). According to one embodiment, the electronic device (201) may transmit charging end state information to the first external electronic device (203). If the first external electronic device (203) includes a display (e.g., display (221) of FIG. 2A), the first external electronic device (203) may output the received charging end state information.

[0129] In operation 711, the first external electronic device (203) can check whether it is in a closed or open state and transmit information related to the confirmed open / closed state to the electronic device (201).

[0130] In operation 713, the electronic device (201) can receive information related to the open / closed state of the first external electronic device (203) to determine whether it is in a closed state. If, upon confirmation, information regarding the open state is received from the first external electronic device (203), the electronic device (201) can terminate the operation without performing the battery deterioration measurement operation and compensation operation settings. If the closed state is confirmed, the electronic device (201) can perform the battery deterioration measurement operation in subsequent operations (operations 715 to 721).

[0131] In operation 715, the electronic device (201) can check whether a first state (e.g., a state in which a temperature change amount value is greater than or equal to a first threshold value) is identified a specified number of times (e.g., 3 times). Here, the state in which the temperature change amount value is greater than or equal to the first threshold value may be, for example, a state in which a delta (delta) of 10 degrees is present. According to one embodiment, the electronic device can obtain a temperature change amount value (e.g., a delta (delta Temp) value between a temperature value at a charging start time point and a temperature value at a CC1 end time point (e.g., a point in time when the temperature is the highest during charging)) by comparing a charging start temperature value included in charging start state information with a charging end temperature value included in the charging end state information.

[0132] As a result confirmed in operation 715 (operation 715 - example), if the first state (e.g., a state in which the temperature change amount value is greater than or equal to the first threshold value) is identified a specified number of times (e.g., 3 times), in operation 717, the electronic device (201) determines that the state of the battery is out of the normal range, and may lower the full charge voltage of the battery (321) to a specified value (e.g., approximately -0.2 V) and transmit battery state information to the second external electronic device (101). Here, the battery state information may include information indicating the currently confirmed deterioration level value of the battery, and in addition, may include voltage values ​​or temperature values ​​before and after the deterioration measurement. The electronic device (201) may set deterioration levels (e.g., levels or operations) according to the charging capacity levels. For example, if the electronic device (201) determines that the deterioration level is 75% or less, it may identify that the battery needs to be replaced. The second external electronic device (101) may identify the current state of the battery based on the received battery state information, or transmit the received battery state information to a server (not shown). In operation 719, the second external electronic device (101) may output notification information (e.g., “Visit a service center and have your battery checked”) set based on the received battery state information. Here, the notification information is described as being set in the second external electronic device (101), but may be set by the electronic device (201) and included in the battery state information or transmitted separately to the first external electronic device (203) and / or the second external electronic device (101). According to one embodiment, the electronic device (201) may transmit the battery state information to the first external electronic device (203). If the first external electronic device (203) includes a display, the first external electronic device (203) may output notification information (e.g., “Visit a service center and have your battery checked”) set based on the battery state information.For example, if the first external electronic device (203) does not include a display, the first external electronic device (203) may notify the risk of battery damage through sound or light through another output interface, such as an audio module or a light-emitting element, based on the received battery status information.

[0133] As a result of checking in operation 715 (operation 715-No), when the first state (e.g., a state in which the temperature change amount value is greater than or equal to the first threshold value) occurs less than a specified number of times, in operation 721, the electronic device (201) can check whether a state in which the voltage change amount value is greater than or equal to the second threshold value (e.g., the second state) is identified as a specified number of times (e.g., 3 times). The electronic device (201) can obtain a voltage change amount value (e.g., a delta value of voltage values ​​before and after full charging) by comparing a charging start voltage value included in the charging start state information and a charging end voltage value included in the charging end state information.

[0134] As a result confirmed in operation 717 (operation 721 - Yes), if a state in which the voltage change amount value is greater than or equal to the second threshold value occurs a specified number of times, in operation 723, the electronic device (201) may identify that the battery life has decreased and transmit battery status information to the second external electronic device (101). Here, the battery status information may include information indicating the currently confirmed deterioration level value of the battery, and in addition, may include a voltage value or temperature value before and after the deterioration measurement. The electronic device (201) may set deterioration levels (e.g., levels or operations) according to the charging capacity levels. For example, if the electronic device (201) confirms a deterioration level in which the charging capacity level is 75% or less, it may identify that the battery needs to be replaced. The electronic device (201) may obtain information related to the confirmed battery life according to the battery deterioration measurement operation, and transmit battery status information including the obtained information related to the battery life to the second external electronic device (101). In operation 725, the second external electronic device (101) may output set notification information (e.g., “Visit a service center and have your battery checked”) based on the received battery status information. According to one embodiment, the electronic device (201) may transmit the battery status information to the first external electronic device (203). If the first external electronic device (203) includes a display, the first external electronic device (203) may output set notification information (e.g., “Visit a service center and have your battery checked”) based on the battery status information. For example, if the first external electronic device (203) does not include a display, the first external electronic device (203) may notify the user of the risk of battery damage through sound or light via another output interface, such as an audio module or a light-emitting element, based on the received battery status information.When the first external electronic device (203) receives battery status information including information related to battery life from the electronic device (201), it can transmit the received battery compensation information to another external electronic device (e.g., the second external electronic device (101) or a server).

[0135] As a result of the confirmation in operation 721 (operation 721 - No), if the second state (e.g., the state in which the voltage change amount is greater than or equal to the second threshold value) occurs less than a specified number of times (e.g., 3 times), in operation 727, the electronic device (201) can measure the actual deterioration degree of the battery through a constant current discharge operation. The electronic device identifies the degree of deterioration as being within a normal range (e.g., a range that is not identified as a time for battery replacement due to battery damage or reduced battery life), and can measure the actual deterioration degree of the battery (321) by activating (turning on) the constant current function (e.g., LED) for a specified time (e.g., 5 seconds) using the constant current discharge operation. The electronic device can confirm the actual deterioration degree by confirming the current consumption within the normal range through the constant current discharge operation. Since it is difficult to accurately measure the constant current discharge operation during the battery charging operation due to the operation of other specific functions, the constant current discharge operation can be performed when the battery is not being used after the battery charging is completed.

[0136] In operation 729, the electronic device may perform a compensation operation to be applied during charging of the battery based on information acquired by the battery deterioration measurement operation. According to one embodiment, the electronic device may set compensation operations for battery deterioration compensation according to the deterioration levels acquired by the battery deterioration measurement operation. The electronic device may perform compensation for the resistance and voltage drop of the battery (321) according to the compensation operations set according to the acquired deterioration levels. The electronic device may set a first compensation operation without compensation information based on the deterioration level being a first deterioration level. The electronic device may set a second compensation operation including first compensation information based on the deterioration level being a second deterioration level. Here, the first compensation information may include a first full charge condition margin value (e.g., +30 mV). The processor (310) may set a third compensation operation including second compensation information based on the deterioration level being a third deterioration level. Here, the second compensation information may include a second full charge condition margin value (e.g., +50 mV) and a first voltage value for full charge voltage reduction (e.g., -0.1 V).

[0137] In operation 731, the electronic device (201) may transmit battery compensation information including information related to set compensation operations to the second external electronic device (101). In operation 733, the second external electronic device (101) may output set notification information (e.g., display battery life cycle and compensation operation on a display) based on the received battery compensation information. According to one embodiment, the electronic device (210) may transmit battery compensation information including information related to set compensation operations to the first external electronic device (203). The first external electronic device (203) receives the battery compensation information from the electronic device (210), and when the first external electronic device (203) includes a display, the first external electronic device (203) may display the set notification information based on the battery compensation information. When the first external electronic device (203) receives battery compensation information from the electronic device (201), it can transmit the received battery compensation information to another external electronic device (e.g., the second external electronic device (101) or a server).

[0138] According to one embodiment, an operating method in an electronic device (e.g., electronic device (201) of FIGS. 2A, 2C, and 3) may include obtaining connection information indicating a connection with a first external electronic device (e.g., first external electronic device (203) of FIGS. 2A and 2B) that provides power to charge a battery (e.g., battery (321) of 3) of the electronic device.

[0139] According to one embodiment, the operating method may include an operation of acquiring charging start status information and storing the charging start information in a memory of the electronic device (e.g., memory (330) of FIG. 3) when charging of the battery starts with power applied from the first external electronic device.

[0144] According to one embodiment, the operating method may further include an operation of identifying the earbuds accommodated in the accommodation space within the case, and an operation of measuring a degree of deterioration of the battery based on the electronic device being accommodated in the accommodation space within a first housing of the case (e.g., the first housing (210) of FIG. 2A) and a second housing (the second housing (220) of FIG. 2A) being closed relative to the first housing.

[0145] According to one embodiment, the operation of performing battery degradation measurement is performed based on at least one of a temperature change value, a voltage change value, or a constant current discharge operation, and the method may further include an operation of stopping the battery degradation measurement based on the earbud being accommodated in the accommodation space inside the first housing of the case and the second housing being in an open state with respect to the first housing.

According to one embodiment, the compensation operation may include an operation of lowering the full charge voltage of the battery to a specified value (-0.2 V) based on a state in which the temperature change value is greater than or equal to a first threshold value occurring a specified number of times (e.g., 3 times).

[0147] According to one embodiment, the method may include an operation of transmitting notification information for notifying a risk related to the battery to at least one of a first external electronic device or a second external electronic device through a communication circuit of the electronic device (e.g., a communication module (340) of FIG. 3) based on the occurrence of a state in which the temperature change value is greater than or equal to a first threshold value a specified number of times.

[0148] According to one embodiment, the operation of performing the battery deterioration measurement may include an operation of obtaining a voltage change amount value by comparing a charge start voltage value included in the charge start state information with a charge end voltage value included in the charge end state information based on a state in which the temperature change amount value is greater than or equal to a first threshold value occurring less than a specified number of times, and an operation of activating a constant current function for a specified time and performing the constant current discharge operation based on a state in which the voltage change amount value is greater than or equal to a second threshold value occurring less than a specified number of times.

[0149] According to one embodiment, the operation of measuring the battery deterioration may further include an operation of identifying a decrease in the life of the battery based on a specified number of occurrences of a state in which the voltage change value is greater than or equal to a second threshold value, and an operation of storing information related to the life of the battery in the memory and transmitting it to at least one of the first external electronic device and the second external electronic device through the communication circuit.

[0150] According to one embodiment, the compensation operation may include an operation of setting a first compensation operation without compensation information corresponding to a first deterioration level among the deterioration levels, an operation of setting a second compensation operation including first compensation information corresponding to a second deterioration level among the deterioration levels, and an operation of setting a third compensation operation including second compensation information corresponding to a third deterioration level among the deterioration levels.

According to one embodiment, the second compensation information may include a second full charge condition margin value (e.g., +50 mV) and a first voltage value for a full charge voltage reduction (e.g., -0.1 V).
