[0003] The embodiments disclosed in this document relate to power control devices and methods. Background Technology

[0004] With the increasing prevalence of electric vehicles powered by electricity, research and development of new vehicle architectures are actively underway. For example, electric vehicles can be powered by rechargeable batteries. Here, rechargeable batteries are rechargeable batteries, which can be interpreted as including both conventional Ni / Cd batteries, Ni / MH batteries, and, more recently, lithium-ion batteries. Among rechargeable batteries, lithium-ion batteries have the advantage of a much higher energy density than conventional Ni / Cd and Ni / MH batteries. Furthermore, lithium-ion batteries can be manufactured to be small and lightweight, and therefore are used as power sources for mobile devices. Recently, the application of lithium-ion batteries has expanded to include power sources for electric vehicles, and lithium-ion batteries are gaining attention as a next-generation energy storage medium.

[0005] Vehicles are rapidly integrating with various information and communication technologies and are constantly evolving from existing hardware-based electronics to software-oriented devices. Therefore, recent vehicles include multiple electronic control units (ECUs) dedicated to specific functions within the vehicle, various sensors, cameras, radars, lidar devices, etc., requiring associated software code. Consequently, vehicle platforms are evolving towards software-defined vehicles (SDVs), where the vehicle's features and functions are primarily implemented through software.

[0006] With the development of software-defined vehicles (SDV), research is underway on technologies to reduce the complexity of the vehicle's circuitry and improve the efficiency of the resources required for power control. Summary of the Invention

[0094] According to one embodiment, battery 401 can be connected to converter circuit 403. Converter circuit 403 can change the voltage of the first power supplied from battery 401 to power control unit 303. For example, converter circuit 403 can change the first voltage of the first power to a second voltage that is lower than the first voltage.

[0095] Furthermore, based on the converter circuit 403, the power control unit 303 can be divided into a first part and a second part, and the first part and the second part can be electrically insulated from each other through an insulating layer so that they are not electrically connected to each other. The first part and the second part can be electrically connected to each other only through the converter circuit 403.

[0103] According to an implementation, a specific area control unit can transmit a third power, which is at least a portion of the second power, to at least one terminal device managed by the specific area control unit via a PoDL circuit. At least one terminal device that has received the third power can receive data from or transmit data to the specific area control unit via the PoDL circuit.

[0104] According to an embodiment, the first power supply path between the power control unit 303 and the battery 401 can be shorter than the second power supply path between at least one area control unit and the battery 401. The power control unit 303 can reduce the resources required for power control and improve the stability of power control by receiving and controlling power before at least one area control unit.

[0105] According to the implementation, when power is managed by the power control device 301, the resources required for battery management may be less than those required for battery management when the power transmitted to the terminal device is not integrated and managed.

[0106] This is because the power control device 301 integrates and manages the power transmitted to the terminal device through the power control unit 303.

[0107] In particular, since the power allocated to each regional control unit can be centrally managed, resource utilization efficiency can be improved when the power transmitted to the terminal device is centrally managed by the power control unit 303, compared to the case where the power transmitted to the terminal device is not centrally managed.

[0108] In addition, according to Figure 5 In the embodiment shown, since the power control unit 303 also performs the role of a regional control unit, the number of required regional control units can be reduced, and correspondingly, the circuit complexity of the power control device 301 can be lower than the circuit complexity when the power control unit 303 does not perform the role of a regional control unit.

[0109] Figure 6 Electrical connections between components of a power control device in a power control device and method according to another embodiment of this document are shown.

[0110] Reference Figure 6 Battery 401 can be electrically connected to power control unit 303. Power control unit 303 can be electrically connected to at least one terminal device (e.g., first terminal device 607, second terminal device 609) included in the electronic device including power control unit 301 to establish dual data lines.

[0111] In other words, at least one terminal device electrically connected to the first area control unit 601 (e.g., the first terminal device 607 and the second terminal device 609), at least one terminal device connected to the second area control unit 603, and at least one terminal device connected to the third area control unit 605 can be electrically connected to the power control unit 303.

[0112] According to an embodiment, the power control unit 303 and at least one terminal device (e.g., first terminal device 607 and second terminal device 609) can transmit or receive power and send or receive data via a PoDL circuit (e.g., Figure 4 The PoDL circuits 407 are electrically connected to each other.

[0113] According to an embodiment, the power control unit 303 may be electrically connected to at least one area control unit (e.g., a first area control unit 501, a second area control unit 503, and a third area control unit 505). The power control unit 303 and the at least one area control unit may be electrically connected to each other via a PoDL circuit.

[0114] According to an embodiment, the power control unit 303 can receive first power from the battery 401, transmit second power, which is at least a part of the first power, to at least one terminal device included in the electronic device including the power control unit 301 via the PoDL circuit, and transmit the second power to each of at least one area control unit (e.g., first area control unit 501, second area control unit 503, and third area control unit 505) via the PoDL circuit.

[0115] At least one terminal device receiving the second power supply can transmit the same data to the power control unit 303 and the specific area control unit corresponding to the terminal device in at least one area control unit via the PoDL circuit. The power control unit 303 can control the power supply based on the data obtained from the at least one terminal device. The specific area control unit can control the function of the at least one terminal device based on the data obtained from the at least one terminal device.

[0116] For example, one of the first terminal devices 607 or the second terminal device 609 that receives the second power can transmit data related to the sensing value of a terminal device to the power control unit 303, and transmit the same data related to the sensing value to the first area control unit 601, which is electrically connected to the first terminal device 607 to manage the first terminal device 607.

[0117] According to the implementation method, the stability of the power control device 301 can be increased by using data line redundancy.

[0118] For example, when first data is transmitted from the terminal device to a specific area control unit instead of from the terminal device to the power control unit 303, the specific area control unit can transmit the first data transmitted to it to the power control unit. Similarly, when second data is transmitted from the terminal device to the power control unit 303 but not from the terminal device to the specific area control unit, the power control unit 303 can transmit the second data transmitted to it to the specific area control unit. By making the data lines redundant, even in the event of a line fault or loss of communication (LoC), the power control device 301 can also transmit data to the power control unit 303 or at least one area control unit.

[0119] Furthermore, according to the implementation, since power can be transmitted to the terminal device via at least one area control unit, a backup path for power transmission can be ensured, thereby increasing the stability of the power control device 301.

[0120] For example, when the second power is not transmitted from the power control unit 303 to the terminal device (e.g., the first terminal device 607 and the second terminal device 609), the power control unit 303 may transmit power to the terminal device via a specific area control unit (e.g., the first area control unit 601).

[0121] Additionally, the power control unit 303 can monitor the connection status between itself and the terminal device at predetermined intervals to check for any abnormalities. If an abnormality is detected, the power control unit 303 can transmit a notification signal regarding the abnormality to a specific area control unit. Upon receiving the notification signal, the specific area control unit can then control the terminal device in place of the power control unit.

[0122] According to the implementation, the first power supply path between the power control unit 303 and the battery 401 can be shorter than the second power supply path between at least one area control unit and the battery 401. By receiving and controlling power before at least one area control unit, the power control unit 303 can reduce the resources consumed by power control and improve the stability of power control.

[0123] According to the implementation, when power is managed by the power control device 301, the resources required for battery management may be less than those required for battery management when the power transmitted to the terminal device is not integrated and managed.

[0124] This is because the power control device 301 integrates and manages the power transmitted to the terminal device through the power control unit 303.

[0125] In particular, since the power allocated to each regional control unit can also be centrally managed, resource utilization efficiency can be improved when the power transmitted to the terminal device through the power control unit 303 is centrally managed compared to the case where the power transmitted to the terminal device is not centrally managed.

[0126] Figure 7 Electrical connections between components of a power control device in a power control device and method according to another embodiment of this document are shown.

[0127] Reference Figure 7 Battery 401 can be electrically connected to power control unit 303. Although not shown, power control unit 303 can be electrically connected to HPC. Power control unit 303 can be electrically connected to at least one area control unit (e.g., first area control unit 701, second area control unit 703, third area control unit 705, and fourth area control unit 707).

[0128] At least one area control unit may be electrically connected to at least one terminal device assigned to be managed by the at least one area control unit. For example, a first area control unit 701 may be electrically connected to a first terminal device 709. A second area control unit 703 may be electrically connected to a second terminal device 711. A third area control unit 705 may be electrically connected to a third terminal device 715. A fourth area control unit 707 may be electrically connected to a fourth terminal device 713.

[0129] According to an embodiment, the power control unit 303 and at least one area control unit can transmit or receive power and send or receive data via a PoDL circuit (e.g., Figure 4 The PoDL circuits 407 are electrically connected to each other.

[0130] According to an embodiment, the power control unit 303 can receive first power from the battery 401 and transmit second power, which is at least a part of the first power, to at least one area control unit via the PoDL circuit.

[0131] According to an embodiment, at least one area control unit can transmit third power, which is at least a part of the second power, to a terminal device via the PoDL circuit.

[0132] At least one terminal device receiving third power can receive data from a region control unit electrically connected to at least one terminal device, or transmit data to a region control unit electrically connected to at least one terminal device via a PoDL circuit.

[0133] When power is managed through the power control device 301, the resources required for battery management may be less than those required for battery management when the power transmitted to the terminal device is not integrated and managed.

[0134] This is because the power control device 301 integrates and manages the power transmitted to the terminal device through the power control unit 303.

[0135] In particular, since the power allocated to each regional control unit can also be managed jointly, when the power transmitted to the terminal device is managed in an integrated manner through the power control unit 303, resource utilization efficiency can be improved compared to when the power transmitted to the terminal device is not managed in an integrated manner.

[0136] According to the implementation method, although in Figure 7 Not shown in the text, but even in such cases Figure 7 In the structure of the power control device 301 shown, data lines or power lines can also be redundant.

[0137] For example, at least one terminal device receiving third power can transmit the same data to the management area control unit (the area control unit assigned to manage the terminal device) and the standby area control unit (the area control unit assigned to perform standby management of the terminal device) via the PoDL circuit.

[0138] For example, when data is not transmitted from a terminal device (e.g., first terminal device 709) to a management area control unit (e.g., first area control unit 701) and is transmitted to a backup area control unit (e.g., second area control unit 703), the data transmitted to the backup area control unit can be transmitted through the backup area control unit to at least one of the management area control unit, the power control unit 303, or a combination thereof.

[0139] For example, the power control unit 303 can transmit power to the terminal device (e.g., the first terminal device 709) through the management area control unit (e.g., the first area control unit 701), and when power is not transmitted through the management area control unit, the power control unit 303 can transmit power to the terminal device through the backup area control unit (e.g., the second area control unit 703).

[0140] According to the implementation, the first power supply path between the power control unit 303 and the battery 401 may be shorter than the second power supply path between at least one area control unit and the battery 401. By receiving and controlling power before at least one area control unit, the power control unit 303 can reduce the resources consumed by power control and improve the stability of power control.

[0145] In the third operation 805, the power control device 301 according to the embodiment can operate the terminal device 307 based on the second power.
