[0003] Recently, active research and development on secondary batteries has been underway. Here, secondary batteries refer to rechargeable batteries, encompassing conventional Ni / Cd and Ni / MH batteries as well as the more recent lithium-ion batteries. Among secondary batteries, lithium-ion batteries have the advantage of significantly higher energy density compared to conventional Ni / Cd and Ni / MH batteries. Furthermore, lithium-ion batteries can be manufactured in a compact and lightweight manner, making them suitable for use as power sources for mobile devices. Recently, their scope of application has expanded to include electric vehicles, drawing attention as a next-generation energy storage medium.

[0038] Additionally, each block may represent a module, segment, or part of code containing one or more executable instructions for executing a specific logical function(s). It should also be noted that in some alternative execution examples, the functions mentioned in the blocks may occur out of order. For instance, two blocks described in succession may actually be executed substantially simultaneously, or the blocks may be executed in reverse order according to their corresponding functions.

[0039] In this embodiment, the term "part" refers to a software or hardware component, such as an FPGA or ASIC, and the "part" performs certain roles. However, the meaning of "part" is not limited to software or hardware. The "part" may be configured to reside in an addressable storage medium or configured to operate one or more processors. Thus, for example, the "part" includes components such as software components, object-oriented software components, class components, and task components, as well as processes, functions, attributes, procedures, subroutines, segments of program code, drivers, firmware, microcode, circuits, data, databases, data structures, tables, arrays, and variables. The functions provided within the components and "parts" may be combined into a smaller number of components and "parts" or further separated into additional components and "parts." Furthermore, the components and "parts" may be implemented to operate one or more CPUs within a device or secure multimedia card.

[0040] The expression “at least one of a, b, and c” described throughout the specification may include ‘a alone’, ‘b alone’, ‘c alone’, ‘a and b’, ‘a and c’, ‘b and c’, or ‘a, b, and c all’.

Here, the computer includes, for example, a notebook, desktop, or laptop equipped with a web browser, and the portable terminal is a wireless communication device that ensures portability and mobility, and may include all types of handheld-based wireless communication devices such as IMT (International Mobile Telecommunication), CDMA (Code Division Multiple Access), W-CDMA (W-Code Division Multiple Access), LTE (Long Term Evolution), communication-based terminals, smartphones, tablet PCs, etc.

[0042] Embodiments of the present disclosure are described below with reference to the attached drawings so that those skilled in the art can easily implement them. However, the present disclosure may be embodied in various different forms and is not limited to the embodiments described herein.

[0043] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the attached drawings.

[0044]

[0045] FIG. 1 is a block diagram of an electronic device (100) according to one embodiment of the present disclosure.

[0046] Referring to FIG. 1, the electronic device (100) may include a memory (110), a processor (120), and a communication interface (130). According to an embodiment, the electronic device (100) may further include a sensor (140). The electronic device (100) illustrated in FIG. 1 may further include at least one component (e.g., a display, an input device, or an output device) other than the components illustrated in FIG. 1.

[0047] According to one embodiment, the memory (110) may include volatile memory and / or non-volatile memory.

[0048] According to one embodiment, the memory (110) may store data used by at least one component of the electronic device (100) (e.g., processor (120)). For example, the data may include software (or related instructions), input data, or output data. In one embodiment, the instructions may cause the electronic device (100) to perform operations defined by the instructions when executed by the processor (120).

[0049] According to one embodiment, the memory (110) may store instructions or data. For example, the memory (110) may store at least one instruction that causes the electronic device (100) (or the processor (120)) to perform various operations when executed by the processor (120). For example, a program (or at least one instruction) stored in the memory (110) may be executed by the processor (120).

[0050] According to one embodiment, the memory (110) may include a plurality of storage devices of different types. For example, the memory (110) may include volatile and / or non-volatile storage media. For example, the memory (110) may include at least one of RAM (random-access memory), ROM (read only memory), eMMC (Embedded Multi-Media Card), or any combination thereof.

[0051] According to one embodiment, the processor (120) may be implemented as a computer or a similar device according to hardware, software, or a combination thereof. Hardware-wise, the processor (120) may be implemented in the form of an electronic circuit that processes electrical signals to perform control functions, and software-wise, it may be implemented in the form of a program that drives the hardware processor (120). According to one embodiment, the processor (120) may be operatively connected to a component (e.g., memory (110) and / or communication interface (130)) included in the electronic device (100) to control the connected component.

[0052] According to one embodiment, the processor (120) may include a central processing unit, an application processor, a graphics processing unit, a neural processing unit (NPU), an image signal processor, a sensor hub processor, or a communication processor.

[0053] Meanwhile, unless otherwise specifically mentioned in the following description, the operation of the electronic device (100) may be interpreted as being performed under the control of the processor (120).

[0054] According to one embodiment, the communication interface (130) establishes a wired communication channel and / or a wireless communication channel between the electronic device (100) and an external device, and can transmit and receive data with the external device through the established communication channel.

[0055] Here, communication, that is, the transmission and reception of data, can be performed via wired or wireless means. To this end, the communication interface (130) may include a wired communication module that connects to the internet, etc., via a LAN (Local Area Network), a mobile communication module that connects to a mobile communication network via a mobile communication base station to transmit and receive data, a short-range communication module that uses a communication method of the WLAN (Wireless Local Area Network) family such as Wi-Fi, a communication method of the WPAN (Wireless Personal Area Network) family such as Bluetooth or Zigbee, a satellite communication module that uses a GNSS (Global Navigation Satellite System) such as GPS (Global Positioning System), or a combination thereof.

[0056] According to one embodiment, the sensor (140) can obtain information regarding components included in the electronic device (100) and / or components operatively connected to the electronic device (100). The electronic device (100) can monitor the status of various components in real time using the sensor (140).

[0057] For example, the sensor (140) can obtain starting status information of a vehicle (e.g., an electric vehicle) including an electronic device (100). The starting status information may include, for example, information regarding whether the vehicle is currently in an ignition ON (or IGN ON) state or an ignition OFF (or IGN OFF) state.

[0058] For example, the sensor (140) can obtain state information of a battery (e.g., a high voltage (HV) battery) operatively connected to the electronic device (100). The state information of the battery may include, for example, the insulation resistance of the battery, the state of charge (SoC), and one of the voltages of each of the plurality of cells included in the battery.

[0059] According to one embodiment, the electronic device (100) can obtain information on the starting status of the vehicle and information on the status of the battery included in the vehicle.

[0060] For example, the electronic device (100) can obtain information about the vehicle using a communication interface (130). The electronic device (100) can monitor the starting status of the vehicle based on the information obtained through communication with various devices included in the vehicle (e.g., the ECU (200) of FIG. 2a).

[0061] For example, the electronic device (100) can obtain information about the vehicle using a sensor (140). The electronic device (100) can monitor the starting status of the vehicle based on information about the operation of the vehicle.

[0062] For example, the electronic device (100) can monitor whether the vehicle is currently in an ON state, an OFF state, or transitioning from an OFF state to an ON state based on the vehicle's starting state information.

[0063] For example, the electronic device (100) can determine whether there is an abnormality in the battery based on the battery's state information.

[0064] According to one embodiment, the electronic device (100) can control the opening and closing states of a first switch and a second switch provided on an electrical path between the battery and the electronic device (100) based on starting state information and battery state information.

[0065] For example, the battery may include a high-voltage battery (e.g., an HV battery).

[0066] For example, the first switch may be provided on a second electrical path between the battery and the first converter (e.g., the second electrical path (282) of FIG. 2a). The first converter may correspond, for example, to a low voltage DC / DC converter (LDC).

[0067] For example, the second switch may be provided on a first electrical path (e.g., the first electrical path (281) of FIG. 2a) between a second converter and an electronic device (100) that are electrically connected to the battery. The second converter may correspond, for example, to an isolated DC / DC converter.

[0068] For example, the first converter and the second converter can convert the voltage output from the battery. The first converter can, for example, reduce the voltage output from the battery and transmitted through the first switch and then supply it to an electrical component (e.g., the electrical component (260) of FIG. 2a) including an electronic device (100). The second converter can, for example, reduce the voltage output from the battery and then supply it to an electrical component including an electronic device (100) through the second switch.

[0069] For example, the electronic device (100) can obtain vehicle starting status information from an electrical component (e.g., ECU (200) of FIG. 2a). As another example, the electronic device (100) can obtain vehicle starting status information using a sensor (140). If the electronic device (100) identifies that the vehicle is in an OFF state based on the starting status information, it can turn off the first switch and turn on the second switch. Through this, the electronic device (100) can receive second power through the second converter without receiving first power from the battery through the first converter. That is, when the vehicle is in an OFF state, the electronic device (100) can cut off the first power supplied from the battery by turning off the first switch and operate based on the second power supplied from the battery by turning on the second switch.

[0070] For example, the electronic device (100) can monitor the vehicle's starting status information and the battery's status information based on the second power. That is, the electronic device (100) can continuously monitor the vehicle's starting status and the battery's status by operating through the second power even when the vehicle's starting is in the OFF state.

[0071] For example, if the electronic device (100) identifies that there is an abnormality in the battery based on the monitored battery status information, it may transmit a notification regarding the battery abnormality to an external device using a communication interface (130). The electronic device (100) may identify that there is an abnormality in the battery, for example, if the insulation resistance of the battery is below a critical resistance, the temperature of the battery is above a critical temperature, or the voltage of the battery exceeds a critical voltage. The external device may include, for example, an external server for repairing and replacing the battery or an external server for fire suppression. The external device may further include, for example, a user terminal corresponding to the electronic device (100). The notification may include, for example, a guide indicating that the battery needs to be replaced or repaired and information regarding the abnormal state of the battery.

[0072] For example, the electronic device (100) can transmit and receive various data with at least one electronic control unit (ECU) using a communication interface (130) based on the second power. The electronic device (100) can transmit and receive the vehicle's driving history (e.g., driving distance, driving time, starting point, destination, real-time location, etc.) and battery status information with, for example, at least one ECU included in the vehicle. The at least one ECU may correspond to, for example, an electrical component inside the vehicle operating based on the second power together with the electronic device (100).

[0073] For example, if the electronic device (100) identifies that the vehicle's ignition has transitioned from OFF to ON based on the ignition status information, it can control the opening and closing state of the switch based on whether the battery's status information satisfies a specified condition. For example, if the battery's status information satisfies a specified condition, the electronic device (100) can turn on the first switch and turn off the second switch. Through this, the electronic device (100) can receive first power from the battery through the first converter and not receive second power through the second converter. That is, when the vehicle's ignition has transitioned from OFF to ON, the electronic device (100) can operate based on the first power supplied from the battery by turning on the first switch, and can cut off the second power supplied from the battery by turning off the second switch.

[0074] For example, an electronic device (100) can identify at least one of the insulation resistance, SoC, and voltage of each of the plurality of cells included in the battery based on the battery's state information. The electronic device (100) can determine whether the battery's state information satisfies a specified condition using at least some of the identified information. For example, the electronic device (100) can determine that the battery's state information satisfies a specified condition if the insulation resistance is greater than or equal to a threshold resistance value and the SoC is greater than or equal to a threshold SoC value. Additionally, or generally, the electronic device (100) can determine that the battery's state information satisfies a specified condition if the difference between the maximum and minimum values ​​of the voltages of the plurality of cells is within a specified range.

[0075] According to one embodiment, the electronic device (100) can receive power from the battery through an electrical path according to the open / closed state of the switch.

[0076] For example, the operation of the electronic device (100) controlling the open / closed state of the switch will be explained in more detail through the conceptual diagrams of FIGS. 2a to 2c to be described later.

[0077]

[0078] FIG. 2a is a conceptual diagram showing a power flow configured by controlling the open / closed state of a switch using an electronic device according to one embodiment of the present disclosure.

[0079] FIG. 2b is a conceptual diagram showing a power flow configured by controlling the open / closed state of a switch using an electronic device according to one embodiment of the present disclosure.

[0080] FIG. 2c is a conceptual diagram showing a power flow configured by controlling the open / closed state of a switch using an electronic device according to one embodiment of the present disclosure.

[0081] Referring to FIG. 2a, according to one embodiment, an electrical component (260) of a vehicle including an electronic device (100) and an ECU (200) can receive power from a battery (250) through an electrical path defined by the open / closed state of a first switch (291) and a second switch (292).

[0082] According to one embodiment, the electronic device (100) may receive power through a first electrical path (281) or a second electrical path (282) by controlling the open / closed state of a first switch (291) and a second switch (292). The first power from the battery (250) may be supplied to an inverter (252) and a motor (254) through the second electrical path (282), or supplied to an electrical component (260) after being converted by a first converter (212). The second power from the battery (250) may be supplied to an electrical component (260) via the second switch (292) after being converted by a second converter (222) through the first electrical path (281).

[0083] FIG. 2b may show a first closed circuit in which the electronic device (100) turns off the first switch (291) and turns on the second switch (292).

[0084] For example, if the electronic device (100) identifies that the vehicle is turned OFF based on the vehicle's starting status information, it can form a first closed circuit in which the battery (250), the second converter (222), the second switch (292), and the electrical components (260) are electrically connected by turning off the first switch (291) and turning on the second switch (292). The electronic device (100) and the ECU (200) can receive second power delivered from the battery (250) to the second converter (222) and the second switch (292) through a first electrical path (271) corresponding to the first closed circuit.

[0085] For example, even when the vehicle's engine is OFF, the electronic device (100) and the ECU (200) can operate through the second power supplied based on the first closed circuit.

[0086] FIG. 2c may show a second closed circuit in which the electronic device (100) turns on the first switch (291) and turns off the second switch (292).

[0087] For example, if the electronic device (100) identifies that the vehicle is in the ON state based on the vehicle's starting state information, it can form a second closed circuit in which the battery (250), the first switch (291), the first converter (212), and the electrical components (260) are electrically connected by turning on the first switch (291) and turning off the second switch (292). The electronic device (100) and the ECU (200) can receive first power delivered from the battery (250) by the first switch (291) and the first converter (212) through a second electrical path (272) corresponding to the second closed circuit.

[0088] For example, when the vehicle is turned ON, the electronic device (100) can control the supply of first power to the inverter (252) and motor (254) by turning on the first switch (291). The vehicle can be driven by operating the inverter (252) and motor (254) based on the first power.
