Technical Field

[0003] Various exemplary embodiments of the inventive concept relate to an electronic device, and more specifically, to an electronic device for generating battery state information by using active blocks. Background Technology

[0004] In electronic devices such as mobile devices, battery state information can be calculated via an application processor (AP). However, keeping the AP continuously active in such devices leads to unnecessary power consumption, and therefore, in specific situations such as when there is low traffic, the AP can switch to a sleep mode as a low-power mode to reduce power consumption. However, when the AP is operating in sleep mode, it may become difficult to continuously calculate the battery state. Therefore, it may be beneficial to provide a method that allows continuous calculation of the battery state even when the AP is operating in sleep mode. Summary of the Invention

[0031] As used herein, the term "when" can be interpreted as meaning "in response to". For example, if it is described that A is configured to execute X when B occurs, this can be interpreted as meaning that A is configured to execute X in response to the occurrence of B.

[0032] Figure 1 This is a diagram used to explain the electronic device 10 according to some example embodiments.

[0033] refer to Figure 1 The electronic device 10 may include an application processor 100, a first battery sensing circuit 200_1 to an Mth battery sensing circuit 200_M (where M is a natural number of 2 or greater), and a first battery 300_1 to an Mth battery 300_M.

[0034] In some example embodiments, the electronic device 10 may be implemented as various computing devices or mobile devices, such as mobile phones, smartphones, tablet PCs, personal digital assistants (PDAs), enterprise digital assistants (EDAs), portable multimedia players (PMPs), digital cameras, music players, portable game consoles, navigation devices, wearable devices, Internet of Things (IoT) devices, Internet of Everything (IoE) devices, e-books, virtual reality (VR) devices, and augmented reality (AR) devices, but the example embodiments are not limited thereto.

[0035] Application processor 100 may be implemented as a system-on-a-chip (SoC). Application processor 100 may include at least one of a central processing unit (CPU), a graphics processing unit (GPU), a digital signal processor (DSP), an image signal processor (ISP), a neural processing unit (NPU), and a microcontroller unit (MCU), but the example embodiments are not limited thereto. In some example embodiments, the processing unit included in application processor 100 may be referred to as a processor.

[0036] Application processor 100 can run an operating system (OS) and various application software. Alternatively or additionally, application processor 100 may include or be connected to a memory interface, peripheral interface (e.g., universal serial bus (USB), display, camera, sensor, etc.), power management circuitry, or security module, thereby jointly controlling and managing electronic device 10.

[0037] In some example embodiments, the application processor 100 may operate in at least two operating modes, such as active mode or sleep mode, but the example embodiments are not limited thereto.

[0038] Active mode can refer to a state in which the main processor (CPU, GPU, DSP, NPU, etc.) and peripheral circuitry in application processor 100 are powered (or normally powered) and provided with clock signals, enabling the OS and applications to operate. In some example embodiments, when operating in active mode, application processor 100 is able to perform high-performance computing and can perform the main functions of the device in real time, such as user interface (UI) processing, network communication, and sensor data processing. When application processor 100 operates in active mode, most of the hardware constituting application processor 100 can operate to provide (or smoothly provide) user experience (UX) and multimedia functions to the user. In some example embodiments, the power consumed by application processor 100 when operating in active mode may be higher (or relatively higher) than when application processor 100 operates in sleep mode. In this document, active mode may be referred to as first mode or normal mode.

[0039] A sleep mode can refer to a state in which some or most of the circuitry of the application processor 100 is deactivated or the clock signal supply is blocked. In some example embodiments, when the application processor 100 operates in sleep mode, the clock signal applied to the main compute block, including the processor, may be stopped, or power to it may be cut off, thereby minimizing (or reducing) standby power. However, functions necessary (or used) to maintain system operation, such as battery status detection, alarms, real-time clock (RTC) signaling, sensor interrupts, and wireless communication packet reception, can be monitored and controlled via the active block 110. In some example embodiments, when user input (power button, touch event, etc.) or external events (timers, wireless signals, etc.) are detected in sleep mode, the application processor 100 can change its operating mode from sleep mode to active mode by reapplying power and clock signals. In this document, sleep mode may be referred to as a second mode or a low-power mode.

[0040] Application processor 100 may include active block 110 and main processor 120.

[0041] Active block 110 may refer to a hardware region, circuitry, or subsystem designed to maintain (or always maintain) certain functions (or core functions) such as power management, security, and system event handling within application processor 100. For example, active block 110 may continue to operate to perform, for example, power management functions, even when application processor 100 is operating in sleep mode. In some example embodiments, active block 110 may be referred to as an always-on block or an always-on domain.

[0042] In some example embodiments, even when the application processor 100 is operating in sleep mode, the active block 110 can receive sensing data from the first battery sensing circuit 200_1 to the Mth battery sensing circuit 200_M.

[0043] In some example embodiments, the active block 110 may include an auxiliary processor, and the auxiliary processor may have lower power consumption than the main processor 120.

[0044] Each of the first battery sensing circuits 200_1 to the Mth battery sensing circuits 200_M can be electrically connected to a corresponding battery in the first battery 300_1 to the Mth battery 300_M. The first battery 300_1 to the Mth battery 300_M can provide operating power for operating the electronic device 10 (or provide the power required or used for operating the electronic device 10). Figure 1The illustrated electronic device 10 includes multiple battery sensing circuits and multiple batteries, but the example embodiment is not limited thereto. For example, the electronic device 10 may include only one battery sensing circuit and only one battery. This will be referenced... Figure 2 Describe it.

[0045] In some example embodiments, the battery sensing circuit may be referred to as a fuel gauge chip, a power management integrated circuit (PMIC), or an interface PMIC (IF PMIC).

[0046] The first battery sensing circuit 200_1 to the Mth battery sensing circuit 200_M can sense the first battery 300_1 to the Mth battery 300_M. For example, the first battery sensing circuit 200_1 to the Mth battery sensing circuit 200_M can generate sensing data based on the values ​​(e.g., voltage) sensed from the first battery 300_1 to the Mth battery 300_M, and the generated sensing data can be provided to the application processor 100.

[0047] Application processor 100 can generate battery state information by calculating the battery state based on received sensing data. In some example embodiments, application processor 100 may use a fuel gauge (FG) algorithm to calculate the battery state.

[0048] The FG algorithm can refer to an algorithm used in real time to calculate state-of-charge information representing the amount of remaining energy in a battery, battery health information representing the degree of battery degradation, and internal short-circuit information indicating whether a short circuit exists within the battery. The FG algorithm can be implemented based on at least one of the equivalent circuit model (ECM) or the electrochemical thermal (ECT) model. An ECM model can refer to a model that uses an equivalent circuit including basic circuit elements such as resistors, capacitors, and voltage sources to simulate the electrical characteristics of a battery. An ECT model can refer to a model that simultaneously considers the electrochemical reactions and thermal characteristics (e.g., heat generation, heat distribution, etc.) within the battery.

[0049] For the energy management (or effective energy management) of electronic device 10, continuous monitoring of battery status may be beneficial (or necessary). However, when application processor 100 operates in sleep mode, the operation of main processor 120 is deactivated, making it difficult to monitor battery status, and consequently, the continuous generation of battery status information may be interrupted. By using activity block 110, electronic devices according to some example embodiments can continue to generate battery status information even when application processor 100 is operating in sleep mode.

[0050] Figure 2 This is a diagram used to explain the electronic device 20a according to some example embodiments. See also... Figure 1 To explain Figure 2Furthermore, redundant descriptions can be omitted.

[0051] refer to Figure 2 , Figure 2 The electronic device 20a can correspond to Figure 1 Electronic device 10. Electronic device 20a may include application processor 100a, battery sensing circuit 200 and battery 300. Battery 300 may provide power for operating electronic device 20a (or provide the power required or used for operating electronic device 20a) via operating voltage VSYS.

[0052] Application processor 100a may include active block 110. Active block 110 may include memory 111 and auxiliary processor 112.

[0053] The memory 111 can store sensing data SD. The sensing data SD can be data provided from the battery sensing circuit 200. (See reference...) Figure 3 Description stored Figure 2 The structure of the sensing data SD in the electronic device 20a.

[0054] The memory 111 can be hardware capable of storing information and accessible by the auxiliary processor 112. For example, the memory 111 may include read-only memory (ROM), random access memory (RAM), dynamic RAM (DRAM), double data rate DRAM (DDR DRAM), synchronous DRAM (SDRAM), static RAM (SRAM), magnetoresistive RAM (MRAM), programmable ROM (PROM), erasable PROM (EPROM), electrical EPROM, flash memory, polymer memory, phase change memory, ferroelectric memory, silicon oxide-nitride-oxide-silicon (SONOS) memory, magnetic card / disk, optical card / disk, or a combination of at least two of these, but the exemplary embodiments are not limited thereto.

[0055] The auxiliary processor 112 can read the sensing data SD stored in the memory 111. The auxiliary processor 112 can generate battery state information BSI by performing calculations using the FG algorithm based on the read sensing data SD. The battery state information BSI can be information representing the state of the battery 300 at the time when the battery sensing circuit 200 senses the battery 300.

[0056] Battery Status Information (BSI) may include various information indicating the state of the battery. In some example embodiments, BSI may include at least one of the following: state of charge information indicating the amount of remaining energy in the battery, state of battery health information indicating the degree of battery degradation, or internal short circuit information indicating whether a short circuit exists within the battery.

[0057] The battery sensing circuit 200 may include an analog-to-digital converter (ADC). The battery sensing circuit 200 may be electrically connected to the battery 300. The battery sensing circuit 200 can monitor the state of the battery 300 by periodically sensing the battery 300, for example, per second, but the example embodiments are not limited thereto. In some example embodiments, the period during which the battery sensing circuit 200 senses the battery 300 may be referred to as a reference period. The battery sensing circuit 200 can sense analog signals (e.g., voltage) from the battery 300, and can obtain the voltage, current, and temperature values ​​of the battery 300 by converting the analog signals into sensing data SD as digital values. Figure 5 A detailed description of how the battery sensing circuit 200 obtains the voltage, current, and temperature values ​​of the battery 300.

[0058] Application processor 100a may periodically receive sensing data SD from battery sensing circuit 200, for example, per second, but exemplary embodiments are not limited thereto. In some example embodiments, the period for receiving sensing data SD may be referred to as a reference period. In some example embodiments, battery sensing circuit 200 may provide sensing data SD to memory 111 in active block 110. Therefore, even when application processor 100a is operating in sleep mode, active block 110 may read sensing data SD stored in memory 111 via auxiliary processor 112 and may generate battery state information BSI.

[0059] In some example embodiments, the application processor 100a may communicate with the battery sensing circuit 200 via an inter-integrated circuit (I2C) protocol.

[0060] Figure 3 This is a diagram used to explain the sensing data SD according to some example embodiments. Figure 4 This is a diagram used to explain the battery sensing circuit 200 and battery 300 according to some example embodiments. Figure 5 This is a diagram used to explain the internal circuitry of a battery 300 according to some example embodiments. See also... Figure 1 and Figure 2 describe Figure 3 , Figure 4 and Figure 5 Furthermore, redundant descriptions can be omitted.

[0061] refer to Figure 3The sensed data SD may include a voltage value V_VAL, a current value I_VAL, and a temperature value T_VAL. Each of the voltage value V_VAL, the current value I_VAL, and the temperature value T_VAL may be a digital value comprising k bits (where k is a natural number of 2 or greater). For example, the voltage value V_VAL, the current value I_VAL, and the temperature value T_VAL may each be a 16-bit value, but the example embodiment is not limited thereto. For example, the voltage value V_VAL, the current value I_VAL, and the temperature value T_VAL may each have a bit value greater than or less than 16 bits.

[0062] The battery sensing circuit 200 can convert analog signals (e.g., voltage) measured from the battery 300 into digital values. The digital values ​​are sensing data SD, which can be provided to the active block 110.

[0063] refer to Figure 4 and Figure 5 The battery 300 may include a current sensing resistor 310, a battery cell 320, and a voltage divider circuit 330. The voltage divider circuit 330 may include a reference resistor 331 and a thermistor 332.

[0064] Here, when the battery sensing circuit 200 senses the battery 300, it can mean that the battery sensing circuit 200 measures the voltage at the two ends of each of the current sensing resistor 310 included in the battery 300, the battery cell 320, and the thermistor 332 included in the voltage divider circuit 330.

[0065] The operating voltage VSYS used to operate application processor 100a (or required to operate application processor 100a) can be output via the first terminal of current sensing resistor 310. The first terminal of current sensing resistor 310 can be electrically connected to application processor 100a. The second terminal of current sensing resistor 310 can be electrically connected to battery cell 320. Each of the first and second terminals of current sensing resistor 310 can be electrically connected to ADC 210. The voltage difference between the first and second terminals of current sensing resistor 310 can be referred to as a first two-terminal voltage VD1. ADC 210 can convert the first two-terminal voltage VD1 into a digital value. Battery sensing circuit 200 can generate a current value I_VAL based on the digital value corresponding to the first two-terminal voltage VD1. The current value I_VAL can be a value corresponding to the current of battery 300 (e.g., the output current of battery 300).

[0066] A first terminal of battery cell 320 can be electrically connected to current sensing resistor 310. A second terminal of battery cell 320 can be electrically connected to ADC 210. Each of the first and second terminals of battery cell 320 can be electrically connected to ADC 210. The voltage difference between the first and second terminals of battery cell 320 can be referred to as a second two-terminal voltage VD2. ADC 210 can convert the second two-terminal voltage VD2 into a digital value. Battery sensing circuit 200 can generate a voltage value V_VAL based on the digital value corresponding to the second two-terminal voltage VD2. The voltage value V_VAL can be a value corresponding to the voltage of battery 300 (e.g., the output voltage of battery 300).

[0067] Thermistor 332 may be a component whose resistance value changes according to the temperature of battery 300. In some example embodiments, thermistor 332 may be a negative temperature coefficient (NTC) thermistor. An NTC thermistor may have the characteristic that its resistance decreases as the temperature increases. Here, the description is provided assuming that thermistor 332 is an NTC thermistor, but the example embodiments are not limited thereto. For example, thermistor 332 may be a positive temperature coefficient (PTC) thermistor.

[0068] A power supply voltage VDD can be applied to the first terminal of reference resistor 331. The second terminal of reference resistor 331 can be electrically connected to the first terminal of thermistor 332. The first and second terminals of thermistor 332 can be electrically connected to ADC 210. The first terminal of thermistor 332 can be electrically connected to the second terminal of reference resistor 331. The second terminal of thermistor 332 can be electrically connected to a ground node. In some example embodiments, the power supply voltage VDD can be a voltage generated by a PMIC located in electronic device 20a. The power supply voltage VDD can be different from the operating voltage VSYS.

[0069] The voltage difference between the first and second terminals of the thermistor 332 can be referred to as the third dual-terminal voltage VD3. The ADC 210 can convert the third dual-terminal voltage VD3 into a digital value. The battery sensing circuit 200 can generate a temperature value T_VAL based on the digital value corresponding to the third dual-terminal voltage VD3. The temperature value T_VAL can be a value corresponding to the temperature of the battery 300.

[0070] Figure 6 This is a diagram used to explain the electronic device 20b according to some example embodiments. See also... Figure 1 and Figure 2 To explain Figure 6 Furthermore, redundant descriptions can be omitted.

[0071] refer to Figure 6 , Figure 6The electronic device 20b can correspond to Figure 1 Electronic device 10. Figure 6 The electronic device 20b can be similar to Figure 2 The electronic device 20a is configured, but with Figure 2 The electronic device 20a is different. Figure 6 The electronic device 20b may include multiple batteries. Figure 6 The electronic device 20b shown includes two batteries, for example, a first battery 300_1 and a second battery 300_2, but the example embodiment is not limited thereto.

[0072] The electronic device 20b may include an application processor 100a, a first battery sensing circuit 200_1, a second battery sensing circuit 200_2, a first battery 300_1, and a second battery 300_2.

[0073] Each of the first battery 300_1 and the second battery 300_2 can provide power for operating the electronic device 20b via the operating voltage VSYS (or can provide the power used or required for operating the electronic device 20b).

[0074] The first battery sensing circuit 200_1 may be electrically connected to the first battery 300_1. The first battery sensing circuit 200_1 may include a first ADC 210_1. The first battery sensing circuit 200_1 may provide the memory 111 with first battery sensing data SD_B1 corresponding to the first battery 300_1 by periodically sensing the first battery 300_1 via the first ADC 210_1.

[0075] The second battery sensing circuit 200_2 can be electrically connected to the second battery 300_2. The second battery sensing circuit 200_2 may include a second ADC 210_2. The second battery sensing circuit 200_2 can periodically sense the second battery 300_2 via the second ADC 210_2 to provide the memory 111 with second battery sensing data SD_B2 corresponding to the second battery 300_2.

[0076] In some example embodiments, each of the first battery sensing data SD_B1 and the second battery sensing data SD_B2 may have the same characteristics as... Figure 3 The sensing data SD shown has the same structure.

[0077] In some example embodiments, the first battery sensing data SD_B1 and the second battery sensing data SD_B2 can be provided to the application processor 100a via the same input / output pin located in the application processor 100a. Communication between the application processor 100a and each of the first battery sensing circuit 200_1 and the second battery sensing circuit 200_2 can follow the I2C protocol.

[0183] In operation S380, the main processor 120 may generate accumulated battery state information (ABSI) based on the sensing data group SDG read according to operation S360. Alternatively or additionally, the main processor 120 may generate battery state information (BSI) based on the sensing data SD received from the battery sensing circuit 200 according to operation S370.

[0184] In operation S390, the electronic device 40a can update the battery state of the electronic device 40a (e.g., the amount of remaining energy in the battery, the degree of battery degradation, and whether there is a short circuit inside the battery) based on the accumulated battery state information ABSI.

[0185] In some example embodiments, the electronic device 40a may also include a display device (such as a monitor). The battery status can be displayed on the display device (such as a monitor) included in the electronic device 40a so that it is visually identifiable by a user.
