[0031] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings.

[0032] FIG. 1 illustrates a system that provides diagnostic information regarding a battery of an electric vehicle according to one embodiment.

[0033] Referring to FIG. 1, a system (110) for providing diagnostic information on a battery of an electric vehicle (300) according to one embodiment may include a user terminal (200) and an electronic device (100) that transmit information on a communication connection status of the electric vehicle (300) to the electronic device (100).

[0034] An electronic device (100) according to an embodiment may correspond to a device that configures and provides various information. The electronic device (100) may be a server device that manages information about a battery of an electric vehicle (300) and information about the vehicle. The electronic device (100) may receive information about a communication connection status of the electric vehicle (300) from a user terminal (200). If the electronic device (100) determines that the communication connection between the user terminal (200) and the electric vehicle (300) has been released based on the information about the communication connection status, the electronic device (100) may transmit a confirmation request as to whether the electric vehicle (300) is being charged through an external server (500), and if the electric vehicle (300) is being charged, the electronic device may provide charging information of the electric vehicle (300) received through the external server (500) to the user terminal (200). The electronic device (100) confirms that the communication connection between the user terminal (200) and the electric vehicle (300) has been released, and transmits a confirmation request as to whether the electric vehicle (300) is being charged through an external server (500). If the electric vehicle (300) is not being charged, the electronic device (100) may transmit a request for first battery information of the electric vehicle (300) from the time the communication connection with the electric vehicle (300) is released to the time the communication connection is resumed to the user terminal (200). If the electronic device (100) confirms that the communication connection between the user terminal (200) and the electric vehicle (300) is in progress, the electronic device (100) may receive battery information of the electric vehicle (300) obtained from an On-Board Diagnostics (OBD) of the electric vehicle (300) from the user terminal (200), and transmit diagnostic information about the battery of the electric vehicle (300) based on the battery information of the electric vehicle (300) to the user terminal (200).

[0035] In one embodiment, the electronic device (100) may correspond to a server or analysis device that provides charging information of an electric vehicle (300) to the user terminal (200) based on whether communication between the user terminal (200) and the electric vehicle (300) is connected and whether the electric vehicle (300) is being charged, or provides charging information of the electric vehicle (300) to the user terminal (200) by communicating with a charging device (400) or an external server (500). That is, the electronic device (100) may be connected to the electric vehicle (300) in communication with the electric vehicle (300), obtain battery information of the electric vehicle (300) from a diagnostic device of the electric vehicle (300), and operate in conjunction with the user terminal (200) to generate diagnostic information about the battery of the electric vehicle (300) based on the battery information of the electric vehicle (300). In addition, the electronic device (100) can operate in conjunction with a charging device (400) that charges the battery of an electric vehicle (300), and can also operate in conjunction with an external server (500) that manages the charging device (400). Meanwhile, only components related to the present embodiment are illustrated in FIG. 1. Therefore, those skilled in the art will understand that, in addition to the components illustrated in FIG. 1, other general-purpose components may be included.

[0036] According to an embodiment, a user terminal (200) may correspond to a terminal used by a user of an electric vehicle (300), and may perform a communication connection with the electric vehicle (300) based on at least one communication method among Bluetooth communication and / or Wi-Fi communication. For example, when the user terminal (200) is in communication connection with the electric vehicle (300), the user terminal (200) may obtain battery information of the electric vehicle (300) from a diagnostic device of the electric vehicle (300). The user terminal (200) may obtain battery information of the electric vehicle (300), transmit the battery information of the electric vehicle (300) to the electronic device (100), and receive diagnostic information about the battery of the electric vehicle (300) obtained by the electronic device (100) based on the battery information of the electric vehicle (300). In addition, the user terminal (200) may obtain battery information of the electric vehicle (300), generate diagnostic information about the battery of the electric vehicle (300), and transmit the diagnostic information about the battery of the electric vehicle (300) to the electronic device (100). When the communication between the user terminal (200) and the electric vehicle (300) is in a disconnected state, the user terminal (200) can transmit a request to the electronic device (100) to check whether the electric vehicle (300) is being charged. After the user terminal (200) transmits the request to check whether the electric vehicle (300) is being charged from the electronic device (100), the user terminal (200) can receive a response indicating that the electric vehicle (300) is being charged based on the result confirmed by the electronic device (100) through the charging device (400) or the external server (500). When the electric vehicle (300) is being charged, the user terminal (200) can receive charging information of the electric vehicle (300) obtained through a connection through Power Line Communication (PLC) between the charging device (400) confirmed by the electronic device (100) and the battery management system (BMS) included in the electric vehicle (300), from the electronic device (100).The charging information of the electric vehicle (300) may include time-series information of at least one of the current, voltage, initial SoC, internal resistance, and internal temperature of the battery as the charging of the battery built into the electric vehicle (300) progresses.

[0037] An electric vehicle (300) according to one embodiment may include a diagnostic device (OBD) and an ECU. The diagnostic device (OBD) may receive various information about the electric vehicle from a battery management system (BMS) through the ECU and transmit the information to a user terminal (200). In one embodiment, the electric vehicle (300) may establish a Bluetooth communication connection with a user terminal (200) used by a user of the electric vehicle (300) within a distance where Bluetooth communication is possible. The electric vehicle (300) may disconnect from the user terminal (200) when the user terminal (200) is separated from the electric vehicle (300) by a distance at which Bluetooth communication is impossible. The electric vehicle (300) can be charged by receiving charging power through the charging device (400) and connected to the charging device (400) through power line communication between the battery management system included in the electric vehicle (300). During the charging time, the distance from the user terminal (200) may be increased due to the user moving outside the electric vehicle (300), and the communication connection may be disconnected. In addition, the electric vehicle (300) may be disconnected from the user terminal (200) when the Bluetooth communication function of the user terminal (200) is deactivated by a user input. When the communication connection with the user terminal (200) is resumed, the electric vehicle (300) can transmit battery information of the electric vehicle (300) from the time of disconnection until the time of resumption of the communication connection to the user terminal (200) through Bluetooth communication through a self-diagnosis device. Hereinafter, the electric vehicle (300) is illustrated as communicating with the user terminal (200) and the charging device (400), but embodiments according to the present disclosure are not limited to a specific embodiment.

[0038] For example, the embodiment in which an electric vehicle (300) communicates with a user terminal (200) to be described below may include not only an embodiment in which the electric vehicle (300) performs Bluetooth communication with the user terminal (200) through a diagnostic device, but also an embodiment in which the electric vehicle (300) transmits battery information of the electric vehicle (300) to the user terminal (200) without going through the diagnostic device.

[0039] For example, in the case where an electric vehicle (300) is being charged by a charging device (400), an embodiment in which the electric vehicle (300) communicates with the charging device (400) may include not only an embodiment in which the electric vehicle (300) transmits battery information to the charging device (400) using PLC communication from a diagnostic device or ECU of the electric vehicle (300), but also an embodiment in which the electric vehicle (300) transmits battery information of the electric vehicle (300) by performing wireless communication with the charging device (400).

[0040] According to an embodiment, a charging device (400) that is linked to a system (110) that provides diagnostic information on a battery of an electric vehicle (300) can supply charging power to the electric vehicle (300) by performing power line communication between a battery management system included in the electric vehicle (300), acquire charging information of the electric vehicle (300), and transmit it to an external server (500) or an electronic device (100) that manages the charging device (400). The charging information of the electric vehicle (300) acquired while the charging device (400) is charging the electric vehicle (300) can be transmitted to the user terminal (200) when the communication connection between the user terminal (200) and the electric vehicle (300) is released via the electronic device (100). The charging information of the electric vehicle (300) can be used by the external server (500) to acquire various information related to the electric vehicle (300) being charged through the charging device (400) and the user terminal (200) of the user who uses the electric vehicle (300).

[0041] Here, the electronic device (100) and the external server (500) may be completely separate and independent objects, but may also exist only conceptually separated within a single device or system. That is, the electronic device (100) may exist in combination with the external server (500) depending on the embodiment. That is, a single computing device having the function of providing battery charging information of an electric vehicle (300) to a user terminal (200) may perform both the functions of the electronic device (100) and the battery management device (200) described below, and therefore, such an embodiment is also considered to fall within the scope of the present disclosure.

[0042] The network (130) includes a Local Area Network (LAN), a Wide Area Network (WAN), a Value Added Network (VAN), a mobile radio communication network, a satellite communication network, and a combination thereof, and is a comprehensive data communication network that enables each entity illustrated in FIG. 1 to communicate smoothly with each other, and may include wired Internet, wireless Internet, and mobile radio communication networks. Communication may include, but is not limited to, PLC, Wi-Fi, Bluetooth, Bluetooth low energy, Zigbee, WFD (Wi-Fi Direct), UWB (ultra wideband), IrDA (infrared Data Association), NFC (Near Field Communication), etc., for example.

[0043] Figure 2 is a block diagram showing the configuration of an electronic device according to one embodiment.

[0044] Referring to FIG. 2, an electronic device (100) according to an embodiment may include a communication interface (101), a memory (102), and a processor (103). The electronic device (100) illustrated in FIG. 2 only illustrates components related to the present embodiment. Therefore, it will be understood by those skilled in the art related to the present embodiment that other general components may be included in addition to the components illustrated in FIG. 2.

[0045] According to one embodiment, a communication interface (101) may perform wired / wireless communication through a network (150) to communicate with a user terminal (200) and an external server (500). An electronic device (100) may communicate with an external electronic device using the communication interface (101). The external electronic device may be a terminal, a device, or a server. In addition, the communication method used by the communication interface (101) may be similar to the communication method used for communication with the network (150).

[0046] According to an embodiment, the memory (102) is hardware that stores various data processed within the electronic device (100). The memory (102) is located within the processor (103) of the electronic device (100) and can store data processed and data to be processed through the processor (103). In addition, the memory (102) can store basic programming and data structures that can provide functions of at least one embodiment of the present disclosure, as well as applications (programs, code modules, commands), drivers, etc. that can provide functions of the embodiments of the present disclosure. The memory (102) may include random access memory (RAM) such as dynamic random access memory (DRAM), static random access memory (SRAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), CD-ROM, Blu-ray or other optical disk storage, hard disk drive (HDD), solid state drive (SSD), or flash memory, but is not limited to the specific cases mentioned in the embodiments according to the present disclosure.

[0047] In one embodiment, the processor (103) may control the overall operation of the electronic device (100) and process data and signals. The processor (103) may be composed of at least one hardware unit. In addition, the processor (103) may operate by one or more software modules generated by executing program codes stored in the memory (102). The processor (103) may include the memory (102), and the processor (103) may execute the program codes stored in the memory (102) to control the overall operation of the electronic device (100) and process data and signals. That is, the processor (103) according to one embodiment may perform the entire process of providing diagnostic information on the battery of the electric vehicle (300) depending on whether the user terminal (200) and the electric vehicle (300) are connected to each other and whether the electric vehicle (300) is charged, which will be described in detail below.

[0048] The electronic device (100) according to the above-described embodiments may include a processor, a memory for storing and executing program data, permanent storage such as a disk drive, a communication port for communicating with an external device, a user interface device such as a touch panel, a key, a button, etc. Methods implemented as software modules or algorithms may be stored on a computer-readable recording medium as computer-readable codes or program commands executable on the processor. Here, the computer-readable recording medium includes a magnetic storage medium (e.g., read-only memory (ROM), random-access memory (RAM), floppy disk, hard disk, etc.) and an optical reading medium (e.g., CD-ROM, DVD: Digital Versatile Disc)). The computer-readable recording medium may be distributed to computer systems connected to a network, so that the computer-readable code may be stored and executed in a distributed manner. The medium may be readable by a computer, stored in a memory, and executed by a processor.

[0049] FIG. 3 is a flowchart for explaining a method for providing diagnostic information regarding a battery of an electric vehicle (300) according to one embodiment.

[0050] Referring to FIG. 3, an electronic device (100) according to an embodiment may receive information regarding a communication connection status of an electric vehicle (300) from a user terminal (200) in step S310. The electronic device (100) may receive a transmission request for information regarding a communication connection status between the user terminal (200) and the electric vehicle (300) from the user terminal (200) at a period corresponding to a specific time interval, and may receive information regarding a communication connection status of the electric vehicle (300) from the user terminal (200) in response to the transmission request. The information regarding the communication connection status of the electric vehicle (300) may include information regarding at least one of a communication connection type, a communication signal strength, a communication information transmission rate, and a communication delay time regarding a communication method performed between the user terminal (200) and the electric vehicle (300).

[0051] According to an embodiment, the electronic device (100) can check whether a communication connection is established between the user terminal (200) and the electric vehicle (300) in step S315. The electronic device (100) can check whether a communication connection is established between the user terminal (200) and the electric vehicle (300) based on information about the communication connection status of the electric vehicle (300). In an embodiment, the electronic device (100) can determine that the communication connection between the user terminal (200) and the electric vehicle (300) is disconnected if the type of communication connection being performed between the user terminal (200) and the electric vehicle (300) is not confirmed, the communication signal strength or the communication information transmission rate is lower than a threshold, or the communication delay time is longer than a threshold based on information about the communication connection status of the electric vehicle (300). In one embodiment, the electronic device (100) can determine the type of communication connection being performed between the user terminal (200) and the electric vehicle (300) through information about the communication connection status of the electric vehicle (300), and if the communication signal strength or communication information transmission rate is above a threshold and the communication delay time is below the threshold, it can be determined that the communication connection status is between the user terminal (200) and the electric vehicle (300).

[0052] According to an embodiment, if the electronic device (100) determines that the communication connection between the user terminal (200) and the electric vehicle (300) is disconnected in step S315, the electronic device (100) may determine whether the electric vehicle (300) is being charged in step S325. For example, if the communication connection between the user terminal (200) and the electric vehicle (300) is disconnected, the electronic device (100) may receive a request from the user terminal (200) to determine whether the electric vehicle (300) is being charged in step S325. The electronic device (100) may transmit a request to determine whether the electric vehicle (300) is being charged through an external server (500) in step S325. The request to determine whether the electric vehicle (300) is being charged may be performed based on identification information of the electric vehicle (300). In other words, the electronic device (100) can determine whether the electric vehicle (300) is being charged through an external server (500) based on the identification information of the electric vehicle (300). The identification information of the electric vehicle (300) may refer to information that can distinguish and identify a specific electric vehicle (300) among the electric vehicles (300) that are connected to the charging device (400) and are being charged.

[0053] For example, the identification information of the electric vehicle (300) may include the electric vehicle (300) charging card number registered in the user terminal (200) or the electronic device (100). The electronic device (100) may receive the identification information of the electric vehicle (300) including the electric vehicle (300) charging card number registered in the user terminal (200) from the user terminal (200), and may transmit a request to the external server (500) to check whether the electric vehicle (300) is being charged by a charging card having the corresponding charging card number through communication with the charging device (400) or the external server (500). If there is an electric vehicle (300) being charged at a charging device (400) using a charging card having the same charging card number as the charging card number received from the user terminal (200), the electronic device (100) can receive a response from an external server (500) indicating that the electric vehicle (300) is being charged, and can determine that the electric vehicle (300) is being charged. For example, the identification information of the electric vehicle (300) can include a QR code present in a specific charging device (400). The electronic device (100) can recognize a scan of the QR code present in a specific charging device (400) from the user terminal (200) and determine that the electric vehicle (300) registered in the user terminal (200) is being charged at the specific charging device (400). However, the identification information of the electric vehicle (300) according to the embodiment of the present disclosure is not limited to the cases mentioned above.

[0054] If the electronic device (100) determines that the electric vehicle (300) is being charged in step S325, the electronic device (100) can provide charging information of the electric vehicle (300) to the user terminal (200) in step S330. The electronic device (100) can provide charging information of the electric vehicle (300) obtained through power line communication between the charging device (400) and the battery management system included in the electric vehicle (300) to the user terminal (200) in step S330. That is, when the communication connection between the user terminal (200) and the electric vehicle (300) is disconnected and the electric vehicle (300) is being charged, the electronic device (100) receives charging information of the electric vehicle (300) obtained through power line communication between the electric vehicle (300) and the charging device (400) from an external server (500), and provides the charging information of the electric vehicle (300) to the user terminal (200), so that even when the user terminal (200) is disconnected from the communication connection with the electric vehicle (300), the electronic device (100) can provide diagnostic information on the battery of the electric vehicle (300) to the user terminal (200). The diagnostic information on the battery of the electric vehicle (300) may include information on the driving distance, driving time, fuel efficiency, and expected driving distance of the electric vehicle (300). Additionally, diagnostic information regarding the battery of the electric vehicle (300) may include information regarding the battery charging pattern of the electric vehicle (300), the battery life score obtained based on the user's electric vehicle (300) driving habits, the battery stress management score, and regenerative braking efficiency based on battery charging statistics data.

[0055] If the electronic device (100) determines in step S325 that the electric vehicle (300) is not being charged, the electronic device (100) may transmit a request for diagnostic information regarding the battery of the electric vehicle (300) after the communication connection with the electric vehicle (300) is resumed to the user terminal (200) in step S340. That is, for example, if the electric vehicle (300) is not being charged, such as when the Bluetooth communication function of the user terminal (200) is released by a user input, but the communication connection between the user terminal (200) and the electric vehicle (300) is in a disconnected state, the electronic device (100) may request the user terminal (200) for diagnostic information regarding the battery of the electric vehicle (300) after the communication connection with the electric vehicle (300) is resumed.
