Description

Technical Field

[0001] Embodiments of the present application relate to the technical field of vehicles, including but not limited to a power distribution method, a power distribution system, and power distribution equipment. Background Art

[0002] With the rapid development of vehicle electrification and intelligence, vehicle power distribution systems are also facing many challenges. For example, the continuous increase in the number of electrical devices in vehicles has led to a gradual increase in power distribution power consumption; the rapid development of technologies such as autonomous driving and intelligent chassis has also put forward higher requirements for the scope of power distribution safety and redundancy requirements; in order to meet the requirements of energy conservation and environmental protection, it is necessary to use the limited battery capacity to improve the endurance, which has put forward higher requirements for power distribution efficiency and accuracy.

[0003] In related technologies, only by increasing the battery capacity and optimizing the connector selection to solve the above problems, this solution will not only increase the space occupied by the battery in the vehicle, but also increase the vehicle weight and even increase the vehicle cost. Therefore, how to perform reasonable power distribution control has become a technical problem to be solved urgently. Summary of the Invention

[0004] In view of this, embodiments of the present application provide a power distribution method, a power distribution system, and power distribution equipment, which can achieve reasonable power distribution control. The power distribution method, power distribution system, and power distribution equipment provided by the embodiments of the present application are implemented as follows:

[0005] A power distribution method provided by an embodiment of the present application is applied to a power distribution system. The power distribution system includes at least one control unit and multiple power supply units. Each control unit is connected to at least one load, and each power supply unit is used to supply power to the load connected to the at least one control unit. Among them, each of the M power supply units among the multiple power supply units is connected to the at least one control unit to supply power to the load connected to the at least one control unit through the M power supply units. M is an integer greater than 1 or equal to 1; the method includes:

[0006] Obtain a first load current of a first load, where the first load is a load that is connected to the at least one control unit and is in an on state;

[0007] When the first load current is greater than or equal to the power supply current corresponding to the M power supply units, control each of the N1 power supply units to be connected to the at least one control unit, so as to supply power to the first load through the M power supply units and the N1 power supply units together. The N1 power supply units are at least one of the multiple power supply units other than the M power supply units.

[0008] In the above embodiments, a redundant power distribution system including multiple power supply units is designed. When the load current corresponding to the load in the power distribution system that is in the on state (e.g., the first load current) is greater than or equal to the power supply current of the M connected power supply units, it indicates that the power consumption demand of the currently on-state load has exceeded the power supply capacity of the M power supply units. Then, by connecting the N1 power supply units other than the M power supply units among the multiple power supply units, the N1 power supply units cooperate with the M power supply units to jointly supply power to the on-state load to meet the power consumption demand of the load. This power distribution method can flexibly adjust whether to connect other power supply units according to the current change of the load, which can not only reduce the impact on the normal operation of the load, but also improve the power distribution efficiency and accuracy, thereby improving the safety and reliability of the power distribution and realizing reasonable power distribution control.

[0009] In some embodiments, the method further includes:

[0010] When the first load current is greater than or equal to the sum of the power supply currents corresponding to the M power supply units and the power supply currents corresponding to the N1 power supply units, and there are no power supply units other than the M power supply units and the N1 power supply units among the multiple power supply units, control the disconnection of the connection between some loads in the first load and the corresponding control units.

[0011] In the above embodiments, when there are no power supply units other than the M power supply units among the multiple power supply units, if the power consumption demand of the currently on-state load exceeds the power supply capacity of the M power supply units, it will cause problems such as the on-state load being unable to work properly and even the power supply units being damaged. Then, controlling the disconnection of some on-state loads reduces the number of on-state loads in the power distribution system. This way, the power consumption of the loads in the power distribution system does not exceed the power supply capacity of the M power supply units, thereby reducing the adverse effects on the normal operation of the load and the power supply units caused by insufficient power supply capacity, and improving the safety and reliability of the power distribution.

[0012] In some embodiments, the controlling the disconnection of the connection between some loads in the first load and the corresponding control units includes:

[0013] According to the power distribution level corresponding to each load in the first load, control the disconnection of the connection between the loads in the first load and the corresponding control units in ascending order of the level until the second load current of the remaining loads in the first load is less than the power supply current corresponding to the multiple power supply units, and then stop disconnecting the loads in the first load.

[0014] In the above embodiments, according to the level of load power distribution, the loads in the on state are disconnected in ascending order from low to high until the power consumption demand of the remaining loads after disconnecting some loads does not exceed the power supply capacity of M power supply units, then the disconnection of the loads is stopped. This method ensures that high-level loads are not closed first, so as to guarantee the normal operation of high-level loads as much as possible. This way of closing the loads is more reliable and improves the reliability of power distribution control.

[0015] In some embodiments, after stopping the disconnection of the loads in the first load, the method further includes:

[0016] When the difference between the second load current of the remaining loads and the supply current corresponding to the multiple power supply units is greater than or equal to the rated current of the target load, connect the target load to the corresponding control unit, where the target load is at least one of the partial loads.

[0017] In the above embodiments, after stopping the closing of the loads, if the difference between the supply currents of all the power supply units in the power distribution system minus the load current corresponding to the remaining unclosed loads in the on state meets the rated current of the closed target load, it means that the current power supply capacity of all the power supply units can meet the normal operation of the remaining unclosed loads and the target load, then control to turn on the target load. This method can flexibly control the turning on of the closed loads without the user manually turning on the closed loads again, improving the flexibility of the power distribution method and also being beneficial to improving the user experience.

[0018] In some embodiments, the method further includes:

[0019] When there is an abnormal power supply unit among the M power supply units and the N1 power supply units, control to disconnect the connection between the abnormal power supply unit and the at least one control unit.

[0020] In the above embodiments, when there is an abnormal power supply unit in the power distribution system, control the abnormal power supply unit to disconnect. This method can effectively isolate the abnormal power supply unit and prevent the normal operation of the loads in the power distribution system, so as to improve the power consumption safety and avoid potential safety hazards.

[0021] In some embodiments, after controlling the disconnection of the connection between the abnormal power supply unit and the at least one control unit, the method further includes:

[0022] When the first load current is greater than or equal to the supply currents corresponding to the effective power supply units among the M power supply units and the N1 power supply units excluding the abnormal power supply unit, control N2 power supply units to be connected to the at least one control unit, so as to supply power to the load connected to the at least one control unit jointly by the effective power supply units and the N2 power supply units, where the N2 power supply units are at least one of the multiple power supply units excluding the M power supply units and the N1 power supply units.

[0023] In the above embodiments, after disconnecting the abnormal power supply unit, the power consumption demand of the currently turned-on load has exceeded the power supply capacity of the turned-on effective power supply units. If there are other power supply units in the power distribution system besides the M power supply units and the N1 power supply units, then by controlling N2 power supply units among the other power supply units, the N2 power supply units cooperate with the effective power supply units to jointly supply power to the load, so as to meet the power consumption demand of the load. This power distribution method can flexibly adjust whether to connect other power supply units according to the current change of the load and the supply current change of the power supply units, so as to reduce the impact on the normal operation of the load caused by turning off the abnormal power supply unit. It can not only improve the power distribution efficiency and accuracy, but also improve the safety and reliability of the power distribution.

[0024] In some embodiments, after controlling the disconnection of the connection between the abnormal power supply unit and the at least one control unit, the method further includes:

[0025] When the first load current is greater than or equal to the supply currents corresponding to the effective power supply units among the M power supply units and the N1 power supply units excluding the abnormal power supply unit, and there are no power supply units in the multiple power supply units other than the M power supply units and the N1 power supply units, control the disconnection of the connection between some loads in the first load and the corresponding control units.

[0026] In the above embodiments, after disconnecting the abnormal power supply unit, the power consumption demand of the currently turned-on load has exceeded the power supply capacity of the turned-on effective power supply units, and there are no other power supply units in the power distribution system besides the M power supply units and the N1 power supply units. Then, by controlling the disconnection of some of the turned-on loads, the number of turned-on loads in the power distribution system is reduced, so that the power consumption of the load does not exceed the power supply capacity of the effective power supply units, thereby reducing the adverse impact on the normal operation of the load caused by turning off the abnormal power supply unit, and thus improving the safety and reliability of the power distribution.

[0027] In some embodiments, the method further includes:

[0028] Obtain the rated current corresponding to the second load, where the second load is a load connected to the at least one control unit and predicted to be turned on during the target period;

[0029] In the case where the sum of the first load current and the rated current corresponding to the second load is greater than or equal to the sum of the supply currents corresponding to the M power supply units and the supply currents corresponding to the N1 power supply units, adjust the power supply units connected to the at least one control unit, or adjust the loads connected to the at least one control unit.

[0030] In the above embodiments, when a load to be turned on (e.g., the second load) is predicted during the future target period, it means that the load power consumption demand will increase. Then, by comparing the load currents corresponding to the currently turned-on loads and the loads to be turned on in the future, as well as the power supply capabilities of the M power supply units and the N1 power supply units, different methods are flexibly adopted to adjust the power distribution control strategy in advance to optimize the power distribution control ability of the power distribution system, thereby improving the reliability of power distribution and achieving more reasonable power distribution control.

[0031] In some embodiments, the adjustment of the power supply units connected to the at least one control unit includes:

[0032] In the case where the sum of the first load current and the rated current corresponding to the second load is greater than or equal to the sum of the supply currents corresponding to the M power supply units and the supply currents corresponding to the N1 power supply units, control N3 power supply units to be connected to the at least one control unit, so that the first load and the second load are powered by the M power supply units, the N1 power supply units, and the N3 power supply units together, where the N3 power supply units are at least one of the multiple power supply units other than the M power supply units and the N1 power supply units.

[0033] In the above embodiments, when the sum of the load currents corresponding to the already turned-on loads and the rated currents of the loads to be turned on is greater than or equal to the supply currents of the already connected M power supply units and N1 power supply units, it means that the power consumption demands of the already turned-on loads and the loads to be turned on have exceeded the power supply capabilities of the currently connected power supply units. If there are other power supply units in the power distribution system besides the already connected power supply units, then by controlling N3 power supply units among the other power supply units, the N3 power supply units cooperate with the already connected power supply units to supply power to the loads together to meet the power consumption demands of the loads. This power distribution method can flexibly adjust whether to connect other power supply units according to the current changes of the loads, so as to adjust the power distribution control strategy in advance, thereby ensuring the normal operation of the loads and improving the reliability of power distribution.

[0034] In some embodiments, adjusting the load connected to the at least one control unit includes:

[0035] When the sum of the first load current and the rated current corresponding to the second load is greater than or equal to the sum of the power supply currents corresponding to the M power supply units and the power supply currents corresponding to the N1 power supply units, and there are no power supply units other than the M power supply units and the N1 power supply units among the multiple power supply units, control the disconnection of the connection between a part of the load in the first load and the corresponding control unit.

[0036] In the above embodiments, when the power consumption demands of the already - turned - on loads and the loads to be turned on have exceeded the power supply capacity of the currently connected power supply units, and there are no other power supply units in the power distribution system except the already - connected M power supply units and N1 power supply units, control the disconnection of some of the loads in the on - state, reducing the number of loads in the on - state in the current power distribution system, so that the power consumption of the loads in the future period does not exceed the power supply capacity of the M power supply units and the N1 power supply units, thereby reducing the adverse effects brought by the newly added loads in the future period on the normal operation of the loads, meeting the power consumption demands of more loads, and thus improving the safety and reliability of power distribution.

[0037] In some embodiments, the method further includes:

[0038] Predict the second load according to at least one of the navigation information, the weather type, and the geographical environment type in the target period.

[0039] In the above embodiments, multiple methods can be used to predict the loads to be turned on (such as the second load) in the future target period. This can not only quickly predict the loads to be turned on in advance, but also improve the accuracy of the prediction results, helping the power distribution system to perform more reasonable power distribution control.

[0040] In some embodiments, the power supply current corresponding to each power supply unit is determined based on the maximum stable current corresponding to each power supply unit.

[0041] In the above embodiments, determining the power supply current of each power supply unit based on the maximum stable current can ensure that each power supply unit can guarantee the stable operation of the load.

[0042] In some embodiments, the power supply current of each power supply unit is greater than or equal to the rated current corresponding to the load with the highest power distribution level among the loads connected to the at least one control unit.

[0043] In the above embodiments, the supply current of each power supply unit is greater than or equal to the rated current of the load with the highest power distribution level, indicating that even if only one power supply unit is available in the power distribution system, the power consumption requirements of the highest-level load can still be met, thus ensuring that necessary high-level loads can operate stably.

[0044] In some embodiments, the multiple power supply units include a main power supply unit and at least one auxiliary power supply unit, and the M power supply units include the main power supply unit.

[0045] In the above embodiments, by designing the main power supply unit and the auxiliary power supply unit, the power distribution system can flexibly control the main and auxiliary power supply units to cooperate in powering the load, improving the reliability of the power distribution system.

[0073] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will further describe the specific technical solutions of the present application in detail with reference to the accompanying drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application but are not intended to limit the scope of the present application.

[0074] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0075] In the following description, reference is made to "some embodiments", which describe a subset of all possible embodiments. However, it can be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

[0076] It should be noted that the terms "first / second / third" involved in the embodiments of the present application are used to distinguish similar or different objects, and do not represent a specific order for the objects. It can be understood that "first / second / third" can be interchanged with a specific order or sequence when allowed, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0077] With the rapid development of vehicle electrification and intelligence, vehicle power distribution systems are also facing many challenges, such as meeting the requirements of energy conservation and environmental protection while reducing power distribution power consumption and improving power distribution safety. For example, the continuous increase in the number of electrical devices in vehicles, such as air conditioners and in-vehicle refrigerators, has led to a gradual increase in power distribution power consumption; with the rapid development of technologies with higher safety levels, such as autonomous driving and intelligent chassis, higher requirements have also been put forward for the scope of power distribution safety and redundancy requirements; at the same time, the demand for energy conservation is becoming increasingly prominent. In order to meet the requirements of energy conservation and environmental protection, it is necessary to improve the cruising range using limited battery capacity, which has put forward higher requirements for power distribution efficiency and accuracy.

[0078] In related technologies, the above problems are only solved by increasing battery capacity, optimizing connector selection, etc. However, although increasing battery capacity can improve the cruising range and meet the power consumption needs of more electrical devices in more vehicles, it will lead to an increase in the space occupied by the battery in the vehicle, an increase in vehicle weight, and even an increase in vehicle cost; in addition, since connectors are used to transmit electrical energy in the power distribution system to ensure that the power supply can reach each electrical device reliably, the continuous increase in the number and types of in-vehicle devices will also increase the difficulty of connector selection, resulting in problems such as a substantial increase in cost.

[0079] It can be seen from this that how to perform reasonable power distribution control to meet the increasingly new requirements such as reducing vehicle power distribution power consumption, improving power distribution safety, meeting vehicle power redundancy requirements, and reducing vehicle cost has become a technical problem to be solved urgently.

[0080] In view of this, the embodiments of the present application provide a power distribution method, a power distribution system, and a power distribution device, which are applied to a power distribution system. The power distribution system includes at least one control unit and multiple power supply units, and each control unit is connected to at least one load; obtain the first load current of the first load, where the first load is a load that is connected to at least one control unit and is in an on state; in the case where the first load current is greater than or equal to the power supply current corresponding to M power supply units, control each of the N1 power supply units to be connected to at least one control unit, so as to supply power to the first load jointly through the M power supply units and the N1 power supply units, where the N1 power supply units are at least one of the multiple power supply units other than the M power supply units. It can flexibly adjust whether to connect other power supply units according to the current change of the load, which can not only reduce the impact on the normal operation of the load, but also improve power distribution efficiency and accuracy, thereby improving the safety and reliability of power distribution and realizing reasonable power distribution control.

[0081] In order to introduce the power distribution method provided by the embodiments of the present application more clearly, first, the application scenario applicable to this method will be introduced.

[0082] The power distribution method provided by the embodiments of the present application can be applied to such as Figure 1The power distribution system in the power distribution equipment shown. Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a power distribution equipment disclosed in an embodiment of the present application. As Figure 1 shown, the power distribution equipment includes a power distribution system 10.

[0089] Optionally, each power supply unit may further include a switching power supply chip (Direct Current to Direct Current Converter, abbreviated as DC / DC converter). The DC / DC converter can reduce the high voltage (such as 300 - 800V, etc.) of the battery module to a low voltage (such as 12V or 24V, etc.), and can also increase the low voltage of the battery module to a high voltage. Different functions of the DC / DC converter are applicable to different power distribution systems. The present application does not make any limitation in this regard.

It can be understood that when the electrical devices in the vehicle are started, the main power supply unit is preferentially used to supply power to the electrical devices. When the main power supply unit cannot meet the power consumption requirements of the electrical devices, the auxiliary power supply unit is then turned on to supply power to the electrical devices jointly by the main power supply unit and the auxiliary power supply unit. When the power consumption requirements of the electrical devices drop within the power supply capacity range of the main power supply unit, the auxiliary power supply unit is then turned off.

[0094] By adopting the above embodiments, by designing the main power supply unit and the auxiliary power supply unit, the power distribution system can flexibly control the main and auxiliary power supply units to cooperate to supply power to the electrical devices, improving the reliability of the power distribution system.

As shown in Figure 2C , the power distribution system includes a main power supply unit 21, auxiliary power supply units 22A to 22N, and in this power distribution system, at least one of the main power supply unit 21, the auxiliary power supply units 22A to 22N can be used to supply power to each electrical device in the vehicle.

[0098] It should be noted that Figures 2A to 2C the connection manner shown in

[0099] It should be noted that the embodiments of the present application do not limit the number and type of the main power supply units in the power distribution system, nor the number and type of the auxiliary power supply units, etc.

[0100] In some embodiments, the power distribution system provided by the embodiments of the present application further includes at least one control unit.

[0101] Optionally, the control unit can be implemented based on a microcontroller unit (MCU for short). Each control unit can distribute the electric energy from the power supply unit to the electrical devices on each main circuit controlled by each control unit to complete the power distribution process.

[0102] It should be noted that the embodiments of the present application do not limit the number and type of the control units in the power distribution system, etc.

[0109] The loads in the vehicle refer to various electrical devices that use the electric energy provided by the power supply unit as energy in the vehicle. For example, electrical devices such as cameras, air conditioners, in - vehicle refrigerators, vehicle lights, display screens, door locks, and in - vehicle audio systems.

[0110] It can be understood that each control unit can be connected to one or more loads, indicating that each control unit can independently control each load connected thereto, meaning that each control unit can flexibly configure and adjust the operating states of the loads connected thereto according to specific requirements.

[0111] In some embodiments, the power distribution system further includes a main control unit.

[0112] Optionally, the main control unit can be implemented based on a microcontroller unit (MCU), and the present application does not limit this.

[0113] Optionally, the main control unit can send control instructions to each control unit to control the power supply unit and the load connected to each control unit through each control unit.

[0114] In some embodiments, each power supply unit in the power distribution system is used to supply power to the loads connected to at least one control unit.

[0115] It can be understood that when the control units in the power distribution system are connected to loads and the loads connected to each control unit are in the on state, the power supply unit in the power distribution system can supply power to the loads in the on state.

[0116] It can be understood that a load in the on state means that the load has been turned on and electric energy needs to be provided to the load to support the normal operation of the load.

[0117] As an example, please refer to Figure 3 , Figure 3 is a schematic structural diagram of another power distribution system disclosed in the embodiments of the present application. As Figure 3 shown, the power distribution system includes a control unit 11, a main power supply unit 21, an auxiliary power supply unit 22, loads 31A to 31N, and a main control unit 41. When the load 31A is in the on state, the main control unit 41 can send a connection instruction to the control unit 11, and the control unit 11 responds to the instruction and controls at least one of the main power supply unit 21 or the auxiliary power supply unit 22 to supply power to the load 31A so that the load 31A can operate normally.

[0118] It should be noted that Figure 3 the connection manner shown in

[0119] In some embodiments, each of the M power supply units among the multiple power supply units of the power distribution system is connected to at least one control unit to supply power to the load connected to the at least one control unit through the M power supply units. It can be understood that the connection of the M power supply units to the at least one control unit means that the M power supply units are in the on state, and the on-load connected to the control unit can be powered by the M power supply units.

[0120] Optionally, the M units are at least one of the multiple power supply units. It should be noted that M is an integer greater than 1 or equal to 1, and the number of the M power supply units is not limited in this application.

[0121] Optionally, the M power supply units include a main power supply unit. It can be understood that in the case where the multiple power supply units include a main power supply unit and at least one auxiliary power supply unit, the load connected to the at least one control unit is preferentially powered by the main power supply unit.

[0122] As an example, as Figure 3 shown in the power distribution system, the main power supply unit 21 (an example of the M power supply units) is connected to the control unit 11, indicating that the on-load 31A is powered by the main power supply unit 21.

[0123] To make the purpose and technical solution of this application clearer and more intuitive, a power distribution method disclosed in this application will be described in detail below with reference to the accompanying drawings.

[0124] Please refer to Figure 4 , Figure 4 which is a schematic flowchart of a power distribution method disclosed in an embodiment of this application. As Figure 4 shown, the method may include the following steps:

[0125] Step 401, the main control unit obtains the first load current of the first load, where the first load is a load that is connected to at least one control unit and is in the on state.

[0126] In the embodiment of this application, the power distribution system includes multiple loads. When at least one of the multiple loads is turned on, the main control unit obtains the load current corresponding to the on-load. For the sake of easy understanding, in the embodiment of this application, the on-load is described as the first load, and the load current corresponding to the on-load is described as the first load current.

[0127] It should be noted that the first load may be at least one load in a vehicle such as a vehicle lamp, a camera, and an air conditioner, and the type of the first load is not limited in this application.

[0128] It should also be noted that the first load can be manually turned on by the user or automatically turned on after the vehicle starts. This application does not make any restrictions on this.

[0129] In the embodiments of the present application, the first load current is used to represent the sum of the actual required currents when all the first loads are turned on and operating normally. The first load current reflects the actual current demand of the first load. For example, when the first load includes a front vehicle lamp and a camera, if the load current of the front vehicle lamp is 5A and the load current of the camera is 1A, it means the first load current is 6A.

[0130] Step 402, the main control unit determines whether the first load current is greater than or equal to the supply current corresponding to the M power supply units. If so, step 403 is executed.

[0131] In the embodiments of the present application, the M power supply units are power supply units that are connected to at least one control unit and are in an on state, and the M power supply units are used to supply power to the first load.

[0132] In some embodiments, the main control unit can obtain the supply current of the M power supply units. The supply current of the M power supply units is used to represent the sum of the supply currents of the M power supply units, and the supply current of the M power supply units reflects the power supply capacity of the M power supply units. For example, if there are two power supply units, the supply current of one power supply unit is 20A and the supply current of the other power supply unit is 10A, then the sum of the supply currents of these two power supply units is 30A.

[0133] In the embodiments of the present application, after the main control unit obtains the first load current corresponding to the first load, it can determine whether to adjust the power distribution method by comparing the magnitudes of the first load current and the supply current corresponding to the M power supply units. If the first load current is greater than or equal to the supply current corresponding to the M power supply units, it means that the current power supply capacity of the M power supply units is lower than the actual current demand corresponding to the first load; if the first load current is less than the supply current corresponding to the M power supply units, it means that the current power supply capacity of the M power supply units is higher than the actual current demand corresponding to the first load and can support the normal operation of the first load.

[0134] In some embodiments, the supply current corresponding to each power supply unit is determined based on the maximum stable current corresponding to each power supply unit. The maximum stable current corresponding to each power supply unit in this embodiment is used to represent the maximum value of the current that each power supply unit can provide for long-term stable operation under normal working conditions. It can be understood that the supply current corresponding to each power supply unit is related to the maximum stable current corresponding to each power supply unit, so that the supply current of each power supply unit can be determined based on the maximum stable current to ensure that each power supply unit can guarantee the stable operation of the load.

[0135] It should be noted that the maximum stable current corresponding to each power supply unit may be different or the same, and the present application does not limit this.

[0136] Optionally, the supply current corresponding to each power supply unit is the product of the maximum stable current corresponding to each power supply unit and the safety supply coefficient corresponding to each power supply unit. It can be understood that taking the product of the maximum stable current corresponding to each power supply unit and the safety supply coefficient corresponding to each power supply unit as the supply current corresponding to each power supply unit can effectively reduce the damage to the power supply unit caused by overload and other situations in the power distribution system.

[0137] For example, when the maximum stable current of a certain power supply unit is 20A and its corresponding safety supply coefficient is 90%, the supply current corresponding to this power supply unit is 20A * 90% = 18A. If the first load current of the first load in the power distribution system exceeds 18A, the power distribution strategy is immediately adjusted. This method does not require waiting until the first load current of the first load exceeds 20A before adjustment, improving the safety and reliability of power distribution control.

[0138] It should be noted that the safety supply coefficients corresponding to each power supply unit may be different or the same, and the present application does not limit this.

[0139] In some embodiments, the supply current of each power supply unit is greater than or equal to the rated current of the load with the highest power distribution level among the loads connected to at least one control unit. It can be understood that the supply current of each power supply unit being greater than or equal to the rated current of the load with the highest power distribution level means that even if only one power supply unit is available in the power distribution system, the power consumption requirements of the highest-level load can still be met, thus ensuring that necessary high-level loads can operate stably.

[0140] It should be noted that the load with the highest power distribution level is usually a load with high requirements for safety. For example, for a vehicle, the load related to autonomous driving can be used as the load with the highest power distribution level. It should also be noted that the load with the highest power distribution level can be determined by those skilled in the art, and the present application does not limit this.

[0141] Step 403, the main control unit controls each of the N1 power supply units to be connected to at least one control unit, so as to supply power to the first load jointly through the M power supply units and the N1 power supply units.

[0142] In an embodiment of the present application, when the first load current is greater than or equal to the power supply current corresponding to M power supply units, it indicates that the power supply capacity of the current M power supply units is lower than the actual current demand corresponding to the first load, and the multiple power supply units in the power distribution system further include other power supply units to be turned on in addition to the M power supply units. Then, the main control unit controls each of the N1 power supply units among the other power supply units to be turned on to be connected to at least one control unit.

[0143] In an embodiment of the present application, after controlling each of the N1 power supply units to be connected to at least one control unit, the M power supply units and the N1 power supply units in the power distribution system jointly supply power to the first load.

[0144] It should be noted that the N1 power supply units are at least one of the multiple power supply units other than the M power supply units, and the present application does not limit this.

[0145] In some embodiments, each control unit in the power distribution system further includes at least one switch unit. The switch unit is used to control the connection of each power supply unit to the corresponding control unit and is also used to control the connection of each load to the corresponding control unit.

[0146] In some embodiments, the main control unit controls each of the N1 power supply units to be connected to at least one control unit, which may include: controlling the switch unit to control each of the N1 power supply units to be connected to at least one control unit.

[0147] As an example, please refer to Figure 5 , Figure 5 which is a schematic structural diagram of another power distribution system disclosed in an embodiment of the present application. As shown in Figure 5 , the power distribution system includes a control unit 11, a main power supply unit 21, an auxiliary power supply unit 22, loads 31A to 31E, and a main control unit 41. Among them, the control unit 11 includes switch units 51A to 51G. The switch unit 51A is used to connect the main power supply unit 21 and the control unit 11. The switch unit 51B is used to connect the auxiliary power supply unit 22 and the control unit 11. The switch unit 51C is used to connect the load 31A and the control unit 11. The switch unit 51D is used to connect the load 31B and the control unit 11. The switch unit 51E is used to connect the load 31C and the control unit 11. The switch unit 51F is used to connect the load 31D and the control unit 11. The switch unit 51G is used to connect the load 31E and the control unit 11.

[0148] Optionally, the switching unit may include an electronic fuse (abbreviated as e-fuse switch), which is an overcurrent protection device for semiconductor devices. The switching unit may also include a high-side driver (abbreviated as HSD switch), which is a load switch located on the positive side of the power supply and directly controls the on / off of the load. It is commonly used to drive high-current loads (such as vehicle lights, windshield wipers, seat heaters, etc.). The type and number of the switching unit in this application are not limited.

[0149] As an example, when loads 31A to 31C shown in Figure 5 are all in the on state, it indicates that loads 31A to 31C are the first loads; at the same time, when the switching unit 51A shown in Figure 5 is in the on state and the switching unit 51B is in the off state, it indicates that the main power supply unit 21 (an example of M power supply units) supplies power to loads 31A to 31C.

[0150] Assume that the sum I(total) of the load currents of loads 31A to 31C is 50A (an example of the first load current), and the supply current I(main) corresponding to the main power supply unit 21 is 40A. Since I(total) > I(main), it indicates that the main power supply unit 21 cannot meet the actual current demand of loads 31A to 31C; because the power distribution system shown in Figure 5 also includes an unactivated auxiliary power supply unit 22 (an example of N1 power supply units), the main control unit 41 sends a connection instruction to the control unit 11. The connection instruction is used to indicate controlling the connection between the auxiliary power supply unit 22 and the control unit 11; the control unit 11 responds to this connection instruction and controls the switching unit 51B to be in the on state, so that the auxiliary power supply unit 22 is connected to the control unit 11, and the auxiliary power supply unit 22 is connected to the power distribution system shown in Figure 5 to supply power to loads 31A to 31C jointly by the main power supply unit 21 and the auxiliary power supply unit 22, so that loads 31A to 31C can operate normally.

[0151] It should be noted that Figure 5 the connection method shown in

[0152] Optionally, when the first load current is greater than or equal to the supply currents corresponding to M power supply units and less than the sum of the supply currents corresponding to M power supply units and the supply currents corresponding to N1 power supply units, control N1 power supply units to be connected to at least one control unit. It can be understood that when the power supply capabilities of M power supply units and N1 power supply units are higher than the actual current demand of the first load, by turning on N1 power supply units to assist M power supply units together to supply power to the first load, the normal operation of the first load can be ensured. Exemplarily, assume that Figure 5 as shown, the supply current I(main) of the main power supply unit 21 is 40A, and the supply current I(auxiliary) of the auxiliary power supply unit 22 is 50A. After turning on the auxiliary power supply unit 22, the supply currents of the main power supply unit 21 and the auxiliary power supply unit 22 are 90A, which can meet the actual current demand of 50A for loads 31A to 31C.

[0153] It can be seen that by implementing the embodiments of the present application, a redundant power distribution system including multiple power supply units is designed. When the load current (e.g., the first load current) corresponding to the load in the power distribution system in the on state is greater than or equal to the supply currents of the M connected power supply units, it means that the power consumption demand of the currently on load has exceeded the power supply capabilities of the M power supply units. Then, by connecting N1 power supply units among the multiple power supply units other than the M power supply units, the N1 power supply units cooperate with the M power supply units to supply power to the on load together to meet the power consumption demand of the load. This power distribution method can flexibly adjust whether to connect other power supply units according to the current change of the load, which can not only reduce the impact on the normal operation of the load, but also improve the power distribution efficiency and accuracy, thereby improving the safety and reliability of the power distribution and realizing reasonable power distribution control.

[0154] Please refer to Figure 6 , Figure 6 which is a schematic flowchart of another power distribution method disclosed in the embodiments of the present application. As Figure 6 shown, the method may include the following steps:

[0155] Step 601, the main control unit obtains the first load current of the first load, where the first load is a load that is connected to at least one control unit and is in the on state.

[0156] Step 602, the main control unit determines whether the first load current is greater than or equal to the supply currents corresponding to M power supply units. If so, execute Step 603.

[0157] Step 603, the main control unit controls each of the N1 power supply units to be connected to at least one control unit, so as to supply power to the first load through the M power supply units and the N1 power supply units together.

[0158] For the implementation manners of steps 601 to 603, reference may be correspondingly made to the content in the foregoing steps 401 to 403, which will not be elaborated here.

[0159] Step 604, the main control unit determines whether the first load current is greater than or equal to the sum of the supply currents corresponding to M power supply units and the supply currents corresponding to N1 power supply units. If so, step 605 is executed.

[0160] In the embodiment of the present application, the first load in the on state changes in real time. For example, during the driving process of a vehicle, different loads are turned on at different times according to actual traffic or user requirements and other factors. Then, it can be understood that the first load current corresponding to the first load also changes in real time.

[0161] In some implementation manners, after the M power supply units and the N1 power supply units jointly supply power to the first load in the power distribution system, the main control unit also needs to obtain the first load current in real time to monitor the change of the first load current.

[0162] In some implementation manners, the main control unit can also obtain the supply currents corresponding to the M power supply units and the supply currents corresponding to the N1 power supply units in real time to determine whether the power supply capabilities of the M power supply units and the N1 power supply units match the actual current demand of the first load.

[0163] In the embodiment of the present application, the main control unit can judge whether it is necessary to adjust the power distribution method by comparing the first load current with the sum of the supply currents corresponding to the M power supply units and the supply currents corresponding to the N1 power supply units. If the first load current is greater than or equal to the sum of the supply currents corresponding to the M power supply units and the supply currents corresponding to the N1 power supply units, it means that the current power supply capabilities of the M power supply units and the N1 power supply units are lower than the actual current demand corresponding to the first load; if the first load current is less than the sum of the supply currents corresponding to the M power supply units and the supply currents corresponding to the N1 power supply units, it means that the current power supply capabilities of the M power supply units and the N1 power supply units are higher than the actual current demand corresponding to the first load and can support the normal operation of the first load.

[0164] Step 605, the main control unit determines whether there are power supply units other than the M power supply units and the N1 power supply units among the multiple power supply units. If so, step 606 is executed; if not, step 607 is executed.

[0165] In some implementation manners, the main control unit can also judge whether there are other power supply units in the power distribution system other than the M power supply units and the N1 power supply units. If there are, other power supply units are preferentially turned on. If not, some loads are turned off.

[0166] Step 606, the main control unit controls at least one power supply unit in the remaining power supply units to be connected to at least one control unit.

[0167] In the embodiment of the present application, when the first load current is greater than or equal to the sum of the power supply currents corresponding to M power supply units and the power supply currents corresponding to N1 power supply units, and there are power supply units other than the M power supply units and the N1 power supply units among the multiple power supply units, the main control unit controls at least one power supply unit in the remaining power supply units to be connected to at least one control unit, so as to supply power to the first load jointly by the M power supply units, the N1 power supply units, and at least one power supply unit in the remaining power supply units.

[0168] It should be noted that the above-mentioned remaining power supply units are the power supply units other than the M power supply units and the N1 power supply units among the multiple power supply units.

[0169] As an example, please refer to Figure 7A , Figure 7A which is a schematic structural diagram of another power distribution system disclosed in the embodiment of the present application. In the power distribution system as shown in Figure 7A , it includes a control unit 11A and a control unit 11B, a main power supply unit 21, an auxiliary power supply unit 22A and an auxiliary power supply unit 22B, loads 31A to 31E, loads 32A to 32D, and a main control unit 41; wherein, the control unit 11A includes switch units 51A to 51G, and the control unit 11B includes switch units 52A to 52F.

[0170] In the case where the loads 31A to 31C and the loads 32A to 32C shown in Figure 7A are all in the on state, it means that the loads 31A to 31C and the loads 32A to 32C are the first load; at the same time, in the case where the switch units 51A, the switch unit 51B, and the switch unit 52A shown in Figure 7A are in the on state, and the switch unit 52B is in the off state, it means that the main power supply unit 21 (an example of M power supply units) and the auxiliary power supply unit 22A (an example of N1 power supply units) jointly supply power to the loads 31A to 31C and the loads 32A to 32C.

[0171] Assume that the sum I(total) of the load currents of the loads 31A to 31C and the loads 32A to 32C is 100A (an example of the first load current), the power supply current I(main) corresponding to the main power supply unit 21 is 40A, and the power supply current I(aux) of the auxiliary power supply unit 22A is 50A. I(total) > I(main) + I(aux), which means that the main power supply unit 21 and the auxiliary power supply unit 22A cannot meet the actual current demand of the loads 31A to 31C and the loads 32A to 32C; since asFigure 7A If the power distribution system shown also includes an unactivated auxiliary power supply unit 22B (an example of a remaining power supply unit), the main control unit 41 sends a connection instruction to the control unit 11B. The connection instruction is used to instruct the control of the connection between the auxiliary power supply unit 22B and the control unit 11B. The control unit 11B responds to the connection instruction and controls the switch unit 52B to be in the on state, so that the auxiliary power supply unit 22B is connected to the control unit 11B, and the auxiliary power supply unit 22B is connected to the power distribution system as shown in Figure 7A to supply power to the loads 31A to 31C and the loads 32A to 32C through the main power supply unit 21, the auxiliary power supply unit 22A, and the auxiliary power supply unit 22B, so that the loads 31A to 31C and the loads 32A to 32C can all operate normally.

[0172] It should be noted that Figure 7A the connection method shown in is only an example, and the various units can also be connected in other ways, which is not limited in this application.

[0173] For the implementation manner of controlling the connection between the power supply unit and at least one control unit in step 606, reference can be made to the content in the foregoing step 403, which will not be elaborated here.

[0174] Step 607, the main control unit controls the disconnection of the connection between some loads in the first load and the corresponding control unit.

[0175] In the embodiment of the present application, when the current of the first load is greater than or equal to the sum of the supply currents corresponding to M power supply units and the supply currents corresponding to N1 power supply units, and there are no power supply units other than the M power supply units and the N1 power supply units among the multiple power supply units, the main control unit controls the disconnection of the connection between some loads in the first load and the corresponding control unit.

[0176] It can be understood that after the main control unit controls the disconnection of the connection between some loads in the first load and the corresponding control unit, the power supply capabilities of the M power supply units and the N1 power supply units can be higher than the actual current requirements corresponding to the remaining loads after the disconnection, so as to support the normal operation of the remaining loads. Among them, the remaining loads after the disconnection are the remaining loads in the first load except for the part of the loads whose connection is disconnected.

[0177] In some implementation manners, the main control unit controls the disconnection of the connection between some loads in the first load and the corresponding control unit, which may include: controlling the switch unit to control the disconnection of the connection between some loads in the first load and at least one control unit.

[0178] As an example, please refer to Figure 7B , Figure 7BIt is a schematic structural diagram of another power distribution system disclosed in an embodiment of the present application. As shown in Figure 7B the power distribution system includes a control unit 11, a main power supply unit 21, an auxiliary power supply unit 22, loads 31A to 31E, and a main control unit 41; among them, the control unit 11 includes switch units 51A to 51G.

[0179] As shown in Figure 7B when loads 31A to 31C are in the on state, it means that loads 31A to 31C are the first loads; at the same time, in the power distribution system shown in Figure 7B when both the main power supply unit 21 (an example of M power supply units) and the auxiliary power supply unit 22 (an example of N1 power supply units) are in the on state, it means that the loads 31A to 31C are powered by the main power supply unit 21 and the auxiliary power supply unit 22 together.

[0180] Assume that the load currents of loads 31A to 31C are 25A, 10A, and 15A respectively, and the sum of the supply current I(main) corresponding to the main power supply unit 21 and the supply current I(aux) corresponding to the auxiliary power supply unit 22 is I(main)+I(aux)=45A. Then, the sum I(total) of the load currents of loads 31A to 31C is 50A (an example of the first load current), and I(total)>I(main)+I(aux); since there are no other unopened power supply units in the power distribution system shown in Figure 7B the main control unit 41 sends a disconnection instruction to the control unit 11, and the disconnection instruction is used to instruct to disconnect the load 31C (an example of a part of the first load) from the control unit 11; the control unit 11 responds to the disconnection instruction and controls the switch unit 51E to be in the off state, so that the load 31C is disconnected from the control unit 11; it can be understood that after the load 31C is disconnected from the control unit 11, I(total) is 35A, and I(total)<I(main)+I(aux), then the power supply capabilities of the main power supply unit 21 and the auxiliary power supply unit 22 are higher than the actual current requirements of loads 31A and 31B, so that loads 31A and 31B can operate normally.

[0181] It should be noted that Figure 7B the connection method shown in is only an example, and the various units can also be connected in other ways, which is not limited in the present application.

[0182] In some embodiments, step 607 can be executed according to the steps shown in Figure 8 Please refer to Figure 8 , Figure 8 It is a schematic flowchart of another power distribution method disclosed in an embodiment of the present application. The method shown in Figure 8 may include the following steps:

[0183] Step 6071: The main control unit disconnects the connection between the loads in the first load and the corresponding control units in ascending order of the power distribution levels corresponding to each load in the first load.

[0184] Optionally, different power distribution levels can be established in advance for each load connected to each control unit in the power distribution system to establish the corresponding relationship between each load connected to each control unit and the power distribution level. Exemplarily, the corresponding relationship between each load connected to each control unit and the power distribution level can refer to Table 1.

[0185] Table 1

[0186]

[0187] It should be noted that in the corresponding relationship between each load connected to each control unit and the power distribution level above, for safety reasons, different power distribution levels are set by those skilled in the art before the vehicle leaves the factory. The power distribution level of each load can be any one of Level 1 to Level N, and the present application does not limit this. It can be understood that the higher the power distribution level, the higher the safety of the corresponding load.

[0188] Optionally, when there are at least two loads in the same power distribution level, the sub-power distribution levels of each load in the same power distribution level can be custom-set by the user, and the present application does not limit this here. For example, both Load 31C and Load 31N are at Level 1, and the user can customize the sub-power distribution levels between Load 31C and Load 31N. For example, the sub-power distribution level of Load 31C can be higher than that of Load 31N.

[0189] In the embodiment shown in Step 6071, when the main control unit disconnects the connection between some loads in the first load and the corresponding control units, in order to avoid turning off all the first loads, the main control unit can control the loads to disconnect in ascending order of the power distribution levels of each load in the first load.

[0190] As an example, as Figure 7B shown, the main control unit 41 sends a disconnection instruction to the control unit 11. The disconnection instruction is used to indicate that the connection between Load 31A to Load 31C and the control unit 11 is controlled to disconnect in ascending order of the power distribution levels of Load 31A to Load 31C. For example, if the power distribution levels of Load 31A to Load 31C are Level 3, Level 2, and Level 1 in sequence, then the control unit 11 responds to this disconnection instruction and first controls the switch unit 51E to be in the off state to disconnect Load 31C from the control unit 11; then controls the switch unit 51D to be in the off state to disconnect Load 31B from the control unit 11.

[0191] Step 6072: The main control unit determines whether the second load current of the remaining load in the first load is less than the supply currents corresponding to multiple power supply units. If so, step 6073 is executed.

[0192] In this embodiment, during the process of the main control unit disconnecting the connection between the load in the first load and the corresponding control unit, the main control unit can also obtain the load current corresponding to the remaining load in the first load. For the sake of easy understanding, the load current corresponding to the remaining load in the first load in the embodiments of the present application is described as the second load current.

[0193] In this embodiment, the supply currents corresponding to multiple power supply units are used to represent the supply currents corresponding to all power supply units in the power distribution system.

[0194] In the embodiment shown in step 6072, the main control unit can also compare the second load current of the remaining load in the first load with the supply currents corresponding to multiple power supply units to determine whether to stop disconnecting the remaining load in the first load. Exemplarily, if the second load current is less than the supply currents corresponding to multiple power supply units, it means that the current supply capacity corresponding to the current multiple power supply units is higher than the actual current demand corresponding to the remaining load, and the main control unit can control to stop disconnecting the remaining load in the first load.

[0195] Step 6073: The main control unit stops disconnecting the load in the first load.

[0196] In this embodiment, until the second load current of the remaining load in the first load is less than the supply currents corresponding to multiple power supply units, the main control unit stops disconnecting the load in the first load.

[0197] As an example, as Figure 7B shown, continuing the example in step 6071 described above, assume that the sum of the supply current I(main) of the main power supply unit 21 and the supply current I(auxiliary) of the auxiliary power supply unit 22 is I(main)+I(auxiliary)=45A. Then, after disconnecting the load 31C, the sum I(total) of the load currents of the remaining loads 31A and 31B is 35A (an example of the second load current), and I(total)<I(main)+I(auxiliary), so the main control unit stops disconnecting the remaining loads 31A and 31B; it can be understood that after the load 31C is disconnected from the control unit 11, the supply capacities of the main power supply unit 21 and the auxiliary power supply unit 22 are higher than the actual current demands of the loads 31A and 31B, and they can jointly supply power to the loads 31A and 31B.

[0198] Adopt the implementation manner shown in the above steps 6071 to 6073. According to the level of load power distribution, turn off the loads in the on state in ascending order from low to high until the power consumption demand of the remaining loads after turning off some loads does not exceed the power supply capacity of M power supply units, and then stop turning off the loads. This method ensures that high-level loads are not turned off first, so as to ensure the normal operation of high-level loads as much as possible. This way of turning off loads is more reliable and improves the reliability of power distribution control.

[0199] Step 6074, the main control unit determines whether the difference between the second load current of the remaining loads and the supply currents corresponding to multiple power supply units is greater than or equal to the rated current of the target load. If so, execute step 6075.

[0200] In this implementation manner, the remaining loads and the corresponding second load current can also change in real time. For example, the user can also manually turn off at least one of the remaining loads according to their own needs. After the user manually turns off at least one of the remaining loads, the corresponding second load current of the remaining loads will decrease.

[0201] In this implementation manner, the main control unit can also obtain the second load current corresponding to the remaining loads in real time to monitor the change of the second load current, and compare the second load current corresponding to the remaining loads with the supply currents corresponding to multiple power supply units to determine whether to turn on the automatically disconnected loads.

[0202] Optionally, the target load is at least one of some of the first loads controlled by the main control unit to be turned off. It can be understood that when the difference between the supply currents corresponding to multiple power supply units minus the second load current of the remaining loads is greater than or equal to the rated current of the target load, it means that if the target load is restarted, the supply currents corresponding to multiple power supply units are higher than the actual current demands of the target load and the remaining loads, and it will not affect the normal operation of the remaining loads.

[0203] Step 6075, the main control unit controls the target load to be connected to the corresponding control unit.

[0204] In the embodiments of the present application, when the difference between the second load current of the remaining loads and the supply currents corresponding to multiple power supply units is greater than or equal to the rated current of the target load, control the target load to be connected to the corresponding control unit.

[0205] As an example, continue to describe based on the example in step 6073 above. In Figure 7BWhen the shown load 31C is controlled by the control unit 11 to be turned off, and the load 31B is manually turned off by the user, assuming that the sum of the supply current I(main) corresponding to the main power supply unit 21 and the supply current I(auxiliary) corresponding to the auxiliary power supply unit 22 is I(main) + I(auxiliary) = 45 A, the load current of the remaining load 31A is 25 A (an example of the second load current), the load current of the load 31C is 15 A (an example of the target load), I(main) + I(auxiliary) - 25 A = 20 A, and this difference of 20 A is greater than the load current of the load 31C, then the main control unit 41 sends a connection instruction to the control unit 11, and the connection instruction is used to instruct to control the connection of the load 31C and the control unit 11; the control unit 11 responds to this connection instruction and controls the switch unit 51E to be in the on state, so that the load 31C is connected to the control unit 11, and the load 31C is connected to the power distribution system as shown in Figure 7B the power distribution system shown. It can be understood that after re-controlling the connection of the load 31C, I(total) is the sum of the load current of the load 31A and the load current of the load 31C, that is, I(total) = 40 A, I(total) < I(main) + I(auxiliary), and the power supply capabilities of the main power supply unit 21 and the auxiliary power supply unit 22 are higher than the actual current demands of the load 31A and the load 31C, and they can jointly supply power to the load 31A and the load 31C.

[0206] Adopting the implementation manners shown in the above steps 6074 to 6075, after stopping turning off the load, if the difference between the supply currents of all the power supply units in the power distribution system minus the load currents corresponding to the remaining unturned-off loads in the on state satisfies the rated current of the turned-off target load, it means that the current power supply capabilities of all the power supply units can meet the normal operation of the remaining unturned-off loads and the target load, then control to turn on the target load. This method can flexibly control the turning on of the turned-off load, without the user having to manually turn on the turned-off load again, improving the flexibility of the power distribution method and also being beneficial to improving the user experience.

[0207] It can be seen that by implementing the embodiments of the present application, it is possible to flexibly adjust whether to connect other power supply units according to the current change of the load, which can not only reduce the impact on the normal operation of the load, but also improve the power distribution efficiency and accuracy, thereby enhancing the safety and reliability of power distribution and achieving reasonable power distribution control. In the case where there are no power supply units other than the M power supply units among multiple power supply units, if the power consumption demand of the currently turned-on load exceeds the power supply capacity of the M power supply units, it may lead to problems such as the inability of the turned-on load to work properly or even damage to the power supply unit. Then, controlling some of the turned-on loads to be disconnected can reduce the number of turned-on loads in the power distribution system, so that the power consumption of the loads in the power distribution system does not exceed the power supply capacity of the M power supply units, thereby reducing the adverse impact on the normal operation of the load caused by insufficient power supply capacity and the adverse impact on the power supply unit, and thus improving the safety and reliability of power distribution.

[0208] Please refer to Figure 9 , Figure 9 which is a schematic flowchart of another power distribution method disclosed in the embodiments of the present application. As Figure 9 shown, the method may include the following steps:

[0209] Step 901, the main control unit obtains the first load current of the first load, where the first load is a load that is connected to at least one control unit and is in the turned-on state.

[0210] Step 902, the main control unit determines whether the first load current is greater than or equal to the power supply current corresponding to the M power supply units. If so, step 903 is executed.

[0211] Step 903, the main control unit controls each of the N1 power supply units to be connected to at least one control unit, so as to supply power to the first load jointly by the M power supply units and the N1 power supply units.

[0212] For the implementation manners of steps 901 to 903, reference can be made to the corresponding content in the foregoing steps 401 to 403, which will not be elaborated here.

[0213] Step 904, the main control unit determines whether there is an abnormal power supply unit among the M power supply units and the N1 power supply units. If so, step 905 is executed.

[0214] Step 905, the main control unit controls the connection between the abnormal power supply unit and at least one control unit to be disconnected.

[0215] In the embodiments of the present application, in the case where there is an abnormal power supply unit among the M power supply units and the N1 power supply units, the connection between the abnormal power supply unit and at least one control unit is controlled to be disconnected.

[0216] In some embodiments, the main control unit controls the disconnection of the abnormal power supply unit from at least one control unit, which may include: controlling the switch unit to disconnect the abnormal power supply unit from at least one control unit, so that the abnormal power supply unit is disconnected from each control unit among at least one control unit.

[0217] As an example, please refer to Figure 10 , Figure 10 which is a schematic structural diagram of another power distribution system disclosed in the embodiments of the present application. In the power distribution system as shown in Figure 10 , it includes a control unit 11, a main power supply unit 21, an auxiliary power supply unit 22, loads 31A to 31E, and a main control unit 41; among them, the control unit 11 includes switch units 51A to 51G, and both the switch unit 51A and the switch unit 51B are in the on state.

[0218] When there is an abnormality in the main power supply unit 21 (an example of an abnormal power supply unit) as shown in Figure 10 , the main control unit 41 sends a disconnection instruction to the control unit 11, and the disconnection instruction is used to instruct to disconnect the main power supply unit 21 from the control unit 11; the control unit 11 responds to the disconnection instruction and controls the switch unit 51A to be in the off state, so that the main power supply unit 21 is disconnected from the control unit 11; it can be understood that after the main power supply unit 21 is disconnected from the control unit 11, the auxiliary power supply unit 22 supplies power to the loads in the on state as shown in Figure 10 .

[0219] It should be noted that Figure 10 the connection manner shown in is only an example, and the various units can also be connected in other ways, and the present application does not limit this.

[0220] It can be seen that implementing the embodiments of the present application can flexibly adjust whether to connect other power supply units according to the current change of the load, which can not only reduce the impact on the normal operation of the load, but also improve the power distribution efficiency and accuracy, thereby improving the safety and reliability of power distribution and realizing reasonable power distribution control. In the case where there is an abnormal power supply unit in the power distribution system, controlling the abnormal power supply unit to disconnect can effectively isolate the abnormal power supply unit and avoid the normal operation of the loads in the power distribution system, so as to improve the power consumption safety and avoid potential safety hazards.

[0221] Please refer to Figure 11 , Figure 11 which is a schematic flowchart of another power distribution method disclosed in the embodiments of the present application. The method as shown in Figure 11 may include the following steps:

[0222] Step 1101, the main control unit obtains the first load current of the first load, where the first load is a load that is connected to at least one control unit and is in an on state.

[0223] Step 1102, the main control unit determines whether the first load current is greater than or equal to the supply current corresponding to M power supply units. If so, step 1103 is executed.

[0224] Step 1103, the main control unit controls each of the N1 power supply units to be connected to at least one control unit, so as to supply power to the first load jointly by the M power supply units and the N1 power supply units.

[0225] For the implementation manners of steps 1101 to 1103, reference may be correspondingly made to the content in the foregoing steps 401 to 403, which will not be elaborated here.

[0226] Step 1104, the main control unit determines whether there is an abnormal power supply unit among the M power supply units and the N1 power supply units. If so, step 1105 is executed.

[0227] Step 1105, the main control unit controls the connection between the abnormal power supply unit and at least one control unit to be disconnected.

[0228] For the implementation manners of steps 1104 to 1105, reference may be correspondingly made to the content in the foregoing steps 904 to 905, which will not be elaborated here.

[0229] Step 1106, the main control unit determines whether the first load current is greater than or equal to the supply current corresponding to the effective power supply units except the abnormal power supply unit among the M power supply units and the N1 power supply units. If so, step 1107 is executed.

[0230] In the embodiment of the present application, after the main control unit controls the connection between the abnormal power supply unit and each control unit among at least one control unit to be disconnected, the remaining power supply units that are not disconnected are effective power supply units.

[0231] In the embodiment of the present application, the control unit may also compare the magnitude relationship between the first load current corresponding to the first load and the supply current corresponding to the effective power supply units, so as to determine whether the power supply capacity of the effective power supply units matches the actual current demand of the first load.

[0232] In the embodiment of the present application, if the first load current corresponding to the first load is greater than or equal to the supply current corresponding to the effective power supply units, it means that the current power supply capacity of the effective power supply units is lower than the actual current demand corresponding to the first load, and then it continues to be determined whether there are power supply units that are not connected except the effective power supply units in the power distribution system.

[0233] Step 1107: The main control unit determines whether there are power supply units other than the M power supply units and the N1 power supply units among the multiple power supply units. If so, step 1108 is executed; if not, step 1109 is executed.

[0234] Step 1108: The main control unit controls the N2 power supply units to be connected to at least one control unit.

[0235] In the embodiment of the present application, when the first load current is greater than or equal to the power supply current corresponding to the effective power supply units other than the abnormal power supply units among the M power supply units and the N1 power supply units, the main control unit controls the N2 power supply units to be connected to at least one control unit.

[0236] In the embodiment of the present application, after controlling the N2 power supply units to be connected to at least one control unit, the load connected to at least one control unit is powered by the effective power supply units and the N2 power supply units together.

[0237] It should be noted that the N2 power supply units are at least one of the multiple power supply units other than the M power supply units and the N1 power supply units, and the present application does not limit this.

[0238] In some embodiments, the main control unit controls the N2 power supply units to be connected to at least one control unit, which may include: controlling each power supply unit of the N2 power supply units to be connected to at least one control unit through a control switch unit.

[0239] Regarding the implementation manners and examples of controlling the N2 power supply units to be connected to at least one control unit in step 1108, reference can be correspondingly made to the content of controlling the N1 power supply units to be connected to at least one control unit in the foregoing step 403, and the content of controlling at least one power supply unit among the remaining power supply units to be connected to at least one control unit in the foregoing step 606, which will not be elaborated here.

[0240] Adopting the implementation manners shown in the above steps 1107 and 1108, after disconnecting the abnormal power supply unit, the power consumption demand of the currently turned-on load has exceeded the power supply capacity of the turned-on effective power supply units. If there are other power supply units in the power distribution system other than the M power supply units and the N1 power supply units, then by controlling the N2 power supply units among the other power supply units, the N2 power supply units cooperate with the effective power supply units to jointly supply power to the load to meet the power consumption demand of the load. This power distribution method can flexibly adjust whether to connect other power supply units according to the current change of the load and the power supply current change of the power supply units, so as to reduce the impact on the normal operation of the load caused by turning off the abnormal power supply unit, which can not only improve the power distribution efficiency and accuracy, but also improve the safety and reliability of the power distribution.

[0241] Step 1109, the main control unit controls the disconnection of the connection between some loads in the first load and the corresponding control units.

[0242] In the embodiment of the present application, when the first load current is greater than or equal to the supply currents corresponding to the effective power supply units among the M power supply units and the N1 power supply units except for the abnormal power supply unit, and there are no power supply units other than the M power supply units and the N1 power supply units among the multiple power supply units, the main control unit controls the disconnection of the connection between some loads in the first load and the corresponding control units.

[0243] Regarding the implementation manners and examples of controlling the disconnection of the connection between some loads in the first load and the corresponding control units in Step 1109, reference may be correspondingly made to the content of controlling the disconnection of the connection between some loads in the first load and the corresponding control units in the foregoing Step 607 and Steps 6071 to 6075, which will not be elaborated here.

[0244] Adopting the implementation manners shown in the foregoing Step 1107 and Step 1109, after disconnecting the abnormal power supply unit, the power consumption demand of the currently turned-on loads has exceeded the power supply capacity of the turned-on effective power supply units, and there are no other power supply units in the power distribution system except for the M power supply units and the N1 power supply units. Then, by controlling the disconnection of some of the turned-on loads and reducing the number of turned-on loads in the power distribution system, the power consumption of the loads does not exceed the power supply capacity of the effective power supply units, thereby reducing the adverse effects on the normal operation of the loads caused by turning off the abnormal power supply unit, and improving the safety and reliability of power distribution.

[0245] It can be seen that implementing the embodiment of the present application can flexibly adjust whether to connect other power supply units according to the current change of the load, which can not only reduce the impact on the normal operation of the load, but also improve the power distribution efficiency and accuracy, thereby improving the safety and reliability of power distribution and realizing reasonable power distribution control. In the case where there is an abnormal power supply unit in the power distribution system, controlling the abnormal power supply unit to disconnect can effectively isolate the abnormal power supply unit and avoid the normal operation of the loads in the power distribution system to improve the power consumption safety and avoid potential safety hazards. It can also flexibly adopt different methods to adjust the power distribution control strategy according to the current change of the load and the change of the supply current of the power supply unit, as well as whether there are other power supply units in the power distribution system, that is, to perform power distribution control by connecting other power supply units or disconnecting some loads, so as to reduce the impact on the normal operation of the load caused by turning off the abnormal power supply unit and improve the safety and reliability of power distribution.

[0246] Please refer to Figure 12 , Figure 12 which is a schematic flowchart of another power distribution method disclosed in the embodiment of the present application. As Figure 12The method shown may include the following steps:

[0247] Step 1201, the main control unit obtains the first load current of the first load, where the first load is a load that is connected to at least one control unit and is in an on state.

[0248] Step 1202, the main control unit determines whether the first load current is greater than or equal to the supply current corresponding to M power supply units. If so, step 1203 is executed.

[0249] Step 1203, the main control unit controls each of the N1 power supply units to be connected to at least one control unit, so as to supply power to the first load jointly by the M power supply units and the N1 power supply units.

[0250] For the implementation manners of steps 1201 to 1203, reference may be correspondingly made to the content in the foregoing steps 401 to 403, which will not be elaborated here.

[0251] Step 1204, the main control unit obtains the rated current corresponding to the second load, where the second load is a load that is connected to at least one control unit and is predicted to be turned on within the target time period.

[0252] In some implementation manners, the power distribution system further includes at least one unturned-on load, and the main control unit can also predict the load to be turned on within the future target time period. For the sake of easy understanding, the load to be turned on within the target time period in the embodiments of the present application is described by taking the second load as an example.

[0253] It should be noted that the target time period can be custom-set by the user or those skilled in the art. For example, during the driving of a vehicle, the load to be turned on within the next 10 minutes or 20 minutes can be predicted, and the present application does not limit the target time period.

[0254] Regarding the above-mentioned second load, in some implementation manners, the second load is predicted according to the navigation information within the target time period.

[0255] Optionally, the navigation information may include information such as a map and the current vehicle speed, and the present application does not limit this. Exemplarily, in the autonomous driving mode, the braking, steering, and light calls of autonomous driving can all be predicted according to the map information in the navigation. For example, if it is predicted through the navigation information that a right curve will be entered in 1 minute, the rated current corresponding to the right turn signal can be obtained, and the power supply unit for ensuring the normal operation of the right turn signal can be prepared 1 minute before entering the curve.

[0256] Regarding the above-mentioned second load, in some other implementation manners, the second load is predicted according to the weather type within the target time period.

[0257] Optionally, the weather type may include types such as rain, snow, heavy fog, etc., and the present application does not limit this.

[0258] Optionally, the weather type can be obtained by sensor monitoring, and the present application does not limit this. For example, a rain sensor can monitor whether the current weather is of the rain type. Exemplarily, when it is monitored that the weather type is rain, it is predicted that the windshield wiper will be enabled, and then the rated current corresponding to the windshield wiper can be obtained to prepare in advance a power supply unit that can satisfy the normal operation of the windshield wiper.

[0259] Regarding the above-mentioned second load, in some other embodiments, the second load is predicted according to the geographical environment type within the target time period.

[0260] Optionally, the geographical environment type may include types such as ramps, tunnels, etc., and the present application does not limit this.

[0261] Optionally, the geographical environment type can be obtained by camera monitoring, and the present application does not limit this. Exemplarily, when it is monitored that the vehicle is about to enter a ramp, since the braking system usually needs to be turned on when entering a ramp, the rated current corresponding to the braking system can be obtained, and a power supply unit that can satisfy the normal operation of the braking system is prepared 10 minutes before entering the ramp.

[0262] For the different embodiments proposed for predicting the second load above, as long as at least one of the above embodiments is adopted, the present application does not limit this. By adopting the above-mentioned multiple embodiments, that is, predicting the load to be turned on (such as the second load) within the future target time period in multiple ways, not only can the load to be turned on be predicted quickly in advance, but also the accuracy of the prediction result can be improved, helping the power distribution system to perform more reasonable power distribution control.

[0263] Step 1205, the main control unit determines whether the sum of the first load current and the rated current corresponding to the second load is greater than or equal to the sum of the supply currents corresponding to the M power supply units and the supply currents corresponding to the N1 power supply units. If so, step 1206 is executed.

[0264] In the embodiment of the present application, the main control unit can also compare the sum of the rated current corresponding to the second load to be turned on within the future target time period and the first load current corresponding to the first load in the on state with the sum of the supply currents corresponding to the M power supply units and the supply currents corresponding to the N1 power supply units, so as to determine whether the power supply capabilities of the M power supply units and the N1 power supply units match the actual current requirements of the first load in the on state and the second load to be turned on.

[0265] In some embodiments, if the sum of the first load current corresponding to the first load and the rated current corresponding to the second load is greater than or equal to the sum of the power supply currents corresponding to M power supply units and the power supply currents corresponding to N1 power supply units, it indicates that the power supply capabilities of the current M power supply units and N1 power supply units are lower than the actual current demands corresponding to the first load and the second load to be turned on.

[0266] Step 1206, the main control unit adjusts the power supply units connected to at least one control unit, or adjusts the loads connected to at least one control unit.

[0267] In some embodiments, when the sum of the first load current and the rated current corresponding to the second load is greater than or equal to the sum of the power supply currents corresponding to M power supply units and the power supply currents corresponding to N1 power supply units, the main control unit adjusts the power supply units connected to at least one control unit.

[0268] Optionally, the main control unit adjusting the power supply units connected to at least one control unit may include: controlling at least one power supply unit other than the M power supply units and the N1 power supply units among the multiple power supply units to be connected to at least one control unit.

[0269] In other embodiments, when the sum of the first load current and the rated current corresponding to the second load is greater than or equal to the sum of the power supply currents corresponding to M power supply units and the power supply currents corresponding to N1 power supply units, the main control unit adjusts the loads connected to at least one control unit.

[0270] It can be seen that implementing the embodiments of the present application can flexibly adjust whether to connect other power supply units according to the current changes of the loads, which can not only reduce the impact on the normal operation of the loads, but also improve the power distribution efficiency and accuracy, thereby improving the safety and reliability of the power distribution and realizing reasonable power distribution control. When it is predicted that there is a load to be turned on (such as the second load) in the future target time period, it indicates that the power consumption demand of the load will increase. Then, by comparing the load currents corresponding to the currently turned-on loads and the loads to be turned on in the future, as well as the power supply capabilities of the M power supply units and the N1 power supply units, different methods are flexibly adopted to adjust the power distribution control strategy in advance to optimize the power distribution control ability of the power distribution system, thereby improving the reliability of the power distribution and realizing more reasonable power distribution control.

[0271] Please refer to Figure 13 , Figure 13 which is a schematic flowchart of another power distribution method disclosed in the embodiments of the present application. As Figure 13 shown, the method may include the following steps:

[0272] Step 1301: The main control unit obtains the first load current of the first load, where the first load is a load that is connected to at least one control unit and is in an on state.

[0273] Step 1302: The main control unit determines whether the first load current is greater than or equal to the supply current corresponding to M power supply units. If so, step 1303 is executed.

[0274] Step 1303: The main control unit controls each of the N1 power supply units to be connected to at least one control unit, so as to supply power to the first load jointly by the M power supply units and the N1 power supply units.

[0275] For the implementation manners of steps 1301 to 1303, reference can be made to the corresponding content in the foregoing steps 401 to 403, which will not be elaborated here.

[0276] Step 1304: The main control unit obtains the rated current corresponding to the second load, where the second load is a load that is connected to at least one control unit and is predicted to be turned on during the target time period.

[0277] Step 1305: The main control unit determines whether the sum of the first load current and the rated current corresponding to the second load is greater than or equal to the sum of the supply current corresponding to the M power supply units and the supply current corresponding to the N1 power supply units. If so, step 1306 is executed.

[0278] For the implementation manners of steps 1304 to 1305, reference can be made to the corresponding content in the foregoing steps 1204 to 1205, which will not be elaborated here.

[0279] Step 1306: The main control unit determines whether there are power supply units other than the M power supply units and the N1 power supply units among the multiple power supply units. If so, step 1307 is executed; if not, step 1308 is executed.

[0280] Step 1307: The main control unit controls the N3 power supply units to be connected to at least one control unit.

[0281] In the embodiment of the present application, when the sum of the first load current and the rated current corresponding to the second load is greater than or equal to the sum of the supply current corresponding to the M power supply units and the supply current corresponding to the N1 power supply units, the main control unit controls the N3 power supply units to be connected to the at least one control unit.

[0282] In the embodiment of the present application, after controlling the N3 power supply units to be connected to at least one control unit, the first load and the second load are jointly powered by the M power supply units, the N1 power supply units and the N3 power supply units.

[0283] It should be noted that the N3 power supply units are at least one of the multiple power supply units other than the M power supply units and the N1 power supply units, and the present application does not limit this.

[0284] In some embodiments, the main control unit controls the connection of the N3 power supply units to at least one control unit, which may include: controlling each power supply unit of the N3 power supply units to be connected to at least one control unit by means of a control switch unit.

[0285] Regarding the embodiments and examples of controlling the connection of the N3 power supply units to at least one control unit in step 1307, reference can be correspondingly made to the content of controlling the connection of the N1 power supply units to at least one control unit in the foregoing step 403, and the content of controlling at least one of the remaining power supply units to be connected to at least one control unit in the foregoing step 606, which will not be elaborated here.

[0286] Adopting the embodiments shown in the above steps 1306 and 1307, when the sum of the load current corresponding to the already - turned - on load and the rated current of the load to be turned on is greater than or equal to the power supply current of the already - connected M power supply units and N1 power supply units, it indicates that the power consumption demands of the already - turned - on load and the load to be turned on have exceeded the power supply capacity of the currently - connected power supply units. If there are other power supply units in the power distribution system besides the already - connected power supply units, then by controlling the N3 power supply units among the other power supply units, the N3 power supply units cooperate with the already - connected power supply units to supply power to the load together, so as to meet the power consumption demands of the load. This power distribution method can flexibly adjust whether to connect other power supply units according to the current change of the load, so as to adjust the power distribution control strategy in advance, thereby ensuring the normal operation of the load and improving the reliability of power distribution.

[0287] Step 1308, the main control unit controls the disconnection of the connection between some loads in the first load and the corresponding control units.

[0288] In the embodiments of the present application, when the sum of the first load current and the rated current corresponding to the second load is greater than or equal to the sum of the power supply current corresponding to the M power supply units and the power supply current corresponding to the N1 power supply units, and there are no power supply units other than the M power supply units and the N1 power supply units among the multiple power supply units, the main control unit controls the disconnection of the connection between some loads in the first load and the corresponding control units.

[0289] Regarding the embodiments and examples of controlling the disconnection of the connection between some loads in the first load and the corresponding control units in step 1308, reference can be correspondingly made to the content of controlling the disconnection of the connection between some loads in the first load and the corresponding control units in the foregoing step 607 and steps 6071 to 6075, which will not be elaborated here.

[0290] Adopting the implementation manners shown in the above-mentioned step 1306 and step 1308, when the power consumption demands of the already-activated load and the to-be-activated load have exceeded the power supply capacity of the currently connected power supply unit, and there are no other power supply units in the power distribution system except the already-connected M power supply units and N1 power supply units, the method controls to disconnect some of the loads in the activated state to reduce the number of loads in the activated state in the current power distribution system, so that the power consumption of the loads in the future time period does not exceed the power supply capacities of the M power supply units and N1 power supply units, thereby reducing the adverse effects on the normal operation of the loads caused by the newly added loads in the future time period, meeting the power consumption demands of more loads, and improving the safety and reliability of power distribution.

[0291] It can be seen that implementing the embodiments of the present application can flexibly adjust whether to connect other power supply units according to the current change of the load. It can not only reduce the impact on the normal operation of the load, but also improve the power distribution efficiency and accuracy, thereby improving the safety and reliability of power distribution and realizing reasonable power distribution control. When it is predicted that there is a to-be-activated load (such as the second load) in the future target time period, indicating that the power consumption demand of the load will increase, by comparing the load currents corresponding to the currently activated load and the to-be-activated load in the future, as well as the power supply capacities of the M power supply units and N1 power supply units, different methods are flexibly adopted to adjust the power distribution control strategy in advance to optimize the power distribution control ability of the power distribution system, thereby improving the reliability of power distribution and realizing more reasonable power distribution control.
