[0002] With the rapid development of vehicle electrification and intelligence, the number of controllable electronic devices in the vehicle's electronic and electrical systems is growing exponentially, driving the accelerated evolution of vehicle electronic and electrical architecture from a traditional distributed architecture to a domain-centralized architecture.

[0033] The following description of a power distribution system and vehicle according to embodiments of the present invention is based on the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described with reference to the accompanying drawings are exemplary and should not be construed as limiting the present invention.

[0034] Figure 1 This is a structural block diagram of the power distribution system according to an embodiment of the present utility model.

[0035] like Figure 1 As shown, the power distribution system 100 includes at least one master node power distribution module 200 and at least two slave node power distribution modules 300. The master node power distribution module 200 is adapted to connect to a power source 400, and the slave node power distribution modules 300 are connected to the master node power distribution module 200 and adapted to connect to a first device 500 to be powered. It should be noted that... Figure 1 This is a specific embodiment where the number of main node power distribution modules 200 is one, but in practical applications, it is not limited to this.

[0036] Specifically, in order to solve the problems of high architecture cost, large size and weight of power distribution schemes in related technologies, a power distribution system 100 as described above is proposed. The power distribution system 100 is equipped with a master node power distribution module 200 and a slave node power distribution module 300, and the power supply 400 and the first device to be powered 500 are connected through the master node power distribution module 200 and the slave node power distribution module 300.

[0037] The input terminal of the master node power distribution module 200 is connected to the power supply 400, and the output terminal of the master node power distribution module 200 is connected to the input terminal of the slave node power distribution module 300. The output terminal of the slave node power distribution module 300 is connected to the first device to be powered 500. In other words, the electrical energy output by the power supply 400 will first reach the master node power distribution module 200, then reach the slave node power distribution module 300, and finally reach the first device to be powered 500.

[0038] The number of slave node power distribution modules 300 is at least two. Therefore, by setting at least two slave node power distribution modules 300 to be connected to the master node power distribution module 200, the slave node power distribution modules 300 can be set in parallel to supply power to each first device to be distributed 500 in parallel. This eliminates the need to use thicker power supply harnesses, thereby reducing weight and cost.

[0039] This allows for power distribution with lower system weight and cost.

[0040] In some embodiments of this invention, the master node power distribution module 200 is also connected to a second device to be powered. In this case, the output terminal of the master node power distribution module 200 is also connected to the power supply terminal of the second device to be powered.

[0041] In some embodiments of this utility model, the master node power distribution module 200 includes a first isolation device, the first end of which is connected to the power supply 400, and the second end of which is adapted to be connected to the slave node power distribution module 300.

[0042] Specifically, in order to achieve safe power supply, a first isolation device is set up. This first isolation device is in the conducting state by default, that is, it does not perform isolation, and the current can flow through the first isolation device normally.

[0043] Furthermore, the first isolation device is configured to detect the current and voltage of its own path, or to detect the temperature at a preset location, such as the location of the first isolation device itself. When the detected current, voltage, or temperature value is higher than a specific value and the duration of the higher value exceeds a preset duration requirement, the first isolation device can disconnect its own path.

[0044] Therefore, by setting up the first isolation device, the connection between the power supply 400 and the slave node power distribution module 300 and / or the second power distribution equipment can be disconnected when at least one of the current, voltage, and temperature is abnormal, thereby achieving safe power supply.

[0045] Furthermore, the first isolation device is configured as a unidirectional isolation device, meaning that when current is detected flowing from the second end of the first isolation device to the first end, the first isolation device also needs to disconnect its own path.

[0046] Therefore, by setting up a first isolation device, cross-current can be prevented.

[0047] In some embodiments of this utility model, the master node power distribution module 200 further includes a second isolation device, the first end of which is adapted to be connected to the second end of the first isolation device, and the second end of which is adapted to be connected to the slave node power distribution module 300.

[0048] Specifically, the second isolation device is in the on state by default, that is, it does not perform isolation, and the current can flow through the second isolation device normally.

[0049] Furthermore, the second isolation device is configured to detect the current and voltage of its own path, or to detect the temperature at a preset location, such as the location of the second isolation device itself. When the detected current, voltage, or temperature value is higher than a specific value and the duration of the higher value exceeds a preset duration requirement, the second isolation device can disconnect its own path.

[0050] Therefore, by setting up the second isolation device, the connection between the power supply 400 and the slave node power distribution module 300 and / or the second power distribution equipment can be disconnected when at least one of the current, voltage, and temperature is abnormal, thereby achieving safe power supply.

[0051] Moreover, the second isolation device is a bidirectional isolation device, meaning that the second isolation device does not determine whether to shut off its own path based on the direction of current flow.

[0052] Therefore, by setting up a second isolation device, cross-current can be prevented.

[0053] In some embodiments of this utility model, both the master node power distribution module 200 and the slave node power distribution module 300 include at least one of a zone controller and a power distribution box. That is, the master node power distribution module 200 and the slave node power distribution module 300 can be implemented using a zone controller, a power distribution box, or both.

[0054] The aforementioned distribution box can be a traditional distribution box or a smart distribution box, with built-in fuses and relays to protect the wiring harness. By using a distribution box, the size of the area controller can be saved.

[0055] In some embodiments of this utility model, the first isolation device includes a first switch and a first controller. The first end of the first switch is connected to the power supply 400, the second end of the first switch is adapted to be connected to the slave node power distribution module 300, and the control end of the first switch is connected to the first controller.

[0056] Specifically, the first isolation device includes a first switch and a first controller. The first controller is used to control the on / off state of the first switch and to determine whether it is necessary to disconnect the path where the first isolation device is located. When it is determined that it is necessary to disconnect the path where the first isolation device is located, the first controller controls the first switch to open, thereby disconnecting the path where the first isolation device is located.

[0057] The first switch mentioned above can be a high-side switch. The first controller mentioned above can be implemented by the area controller in the first isolation device, and the first switch can also be implemented by the area controller in the first isolation device. For example, the area controller in the first isolation device can be configured to integrate a high-side driver and / or a chip, which can collect and interact with information such as current, voltage, and temperature.

[0058] In some embodiments of this utility model, the first isolation device includes a first electronic fuse, the first end of which is connected to a power supply 400, and the second end of which is adapted to be connected to a slave node power distribution module 300.

[0059] Specifically, the first isolation device includes a first electronic fuse. The first electronic fuse is used to determine whether it is necessary to disconnect the path where the first isolation device is located. When it is determined that it is necessary to disconnect the path where the first isolation device is located, the path where the first electronic fuse is located is disconnected, thereby disconnecting the path where the first isolation device is located.

[0060] In some embodiments of this utility model, the second isolation device includes a second switch and a second controller. The first end of the second switch is connected to the power supply 400, the second end of the second switch is adapted to be connected to the slave node power distribution module 300, and the control end of the second switch is connected to the second controller.

[0061] Specifically, the second isolation device includes a second switch and a second controller. The second controller is used to control the on / off state of the second switch and to determine whether it is necessary to disconnect the path where the second isolation device is located. When it is determined that it is necessary to disconnect the path where the second isolation device is located, the second controller controls the second switch to open, thereby disconnecting the path where the second isolation device is located.

[0062] The second switch can be a high-side switch. The second controller can be implemented by the area controller in the second isolation device, and the second switch can also be implemented by the area controller in the second isolation device. For example, the area controller in the second isolation device can be configured to integrate a high-side driver and / or a chip, which can collect and interact with information such as current, voltage, and temperature.

[0063] In some embodiments of this utility model, the second isolation device includes a second electronic fuse, the first end of which is connected to a power supply 400, and the second end of which is adapted to be connected to a slave node power distribution module 300.

[0064] Specifically, the second isolation device includes a second electronic fuse. The second electronic fuse is used to determine whether it is necessary to disconnect the path where the second isolation device is located. When it is determined that it is necessary to disconnect the path where the second isolation device is located, the path where the second electronic fuse is located is disconnected, thereby disconnecting the path where the second isolation device is located.

[0065] In some embodiments of this utility model, the slave node power distribution module 300 includes a third isolation device, the first end of which is adapted to connect to the master node power distribution module 200, and the second end of which is adapted to connect to the first device to be powered 500.

[0066] For details on the application of the third isolation device, please refer to the second isolation device.

[0067] In some embodiments of this utility model, the third isolation device includes a third switch and a third controller. The first end of the third switch is connected to the power supply 400, the second end of the third switch is adapted to be connected to the slave node power distribution module 300, and the control end of the third switch is connected to the third controller.

[0068] For the specific application of the third switch, please refer to the second switch mentioned above; for the specific application of the third controller, please refer to the second controller mentioned above.

[0069] It should be noted that the first controller, second controller, and third controller mentioned above can all be implemented by a regional controller.

[0070] In some embodiments of this utility model, the third isolation device includes a third electronic fuse, the first end of which is connected to the power supply 400, and the second end of which is adapted to be connected to the slave node power distribution module 300.

[0071] For specific applications of the aforementioned third electronic fuse, please refer to the aforementioned second electronic fuse.

[0072] In some embodiments of this utility model, there is one master node power distribution module 200 and multiple slave node power distribution modules 300. The power distribution system 100 also includes a splitter, which includes one input terminal and multiple output terminals. The input terminal of the splitter is connected to the output terminal of the master node power distribution module 200, and the multiple output terminals of the splitter are connected one-to-one with the input terminals of the multiple slave node power distribution modules 300.

[0073] Specifically, a splitter is set up. The splitter is a one-input, multiple-output type, meaning that the number of splitters is the same as the number of master node power distribution modules 200. When there is one master node power distribution module 200, the number of splitters is one; when there are two master node power distribution modules 200, the number of splitters is two; and when there are three master node power distribution modules 200, the number of splitters is three.

[0074] Therefore, when there is one master node power distribution module 200 and multiple slave node power distribution modules 300, there is one splitter. The splitter is used to output the power output by the master node power distribution module 200 to multiple slave node power distribution modules 300.

[0075] The aforementioned splitter can be a junction box, a rigid wire harness backbone (such as a copper plate or aluminum busbar), or a flexible flat cable backbone. The splitter provides multiple wire harness interfaces for easy wire harness branching and electrical connection to the slave node power distribution module 300. Furthermore, the splitter can be connected to each power distribution module using studs, screws, or connectors. If the splitter is a flexible flat cable (FFC), the connection portion is an FFC layered connection. In other embodiments, the splitter may be made of copper plates, traditional wire harnesses, or other materials or designs.

[0076] In some embodiments of this utility model, the power distribution system 100 further includes a DC-DC converter, and the master node power distribution module 200 is adapted to be connected to the power supply 400 through the DC-DC converter.

[0077] Specifically, the power supply 400 can be a 400-800V voltage platform, equipped with a DC-DC converter to convert the high voltage of the vehicle from the 400-800V voltage platform to a low voltage of about 9-60V, and then supply the low voltage to all the equipment to be distributed through the main node power distribution module 200.

[0078] In some embodiments of this utility model, the master node power distribution module 200 and / or the slave node power distribution module 300 are also adapted to connect to energy storage devices.

[0079] Specifically, the aforementioned power distribution system 100 also includes an energy storage device, which provides power backup and short-term current supply when the power supply 400 stops supplying power, thus ensuring the function of protecting important safety loads.

[0080] When power supply 400 is applied, the power distribution module can use power supply 400 to charge the energy storage device. When the vehicle starts or power supply 400 stops, the power distribution module uses the energy storage device to supply power to other first devices 500 connected to the slave node power distribution module 300.

[0081] Moreover, the aforementioned energy storage modules can be configured according to actual conditions. That is, each power distribution module can be equipped with its corresponding energy storage device, or a single energy storage device can be configured to connect all power distribution modules that require energy storage devices.

[0082] In some embodiments of this utility model, the energy storage device is at least one of a battery and a capacitor.

[0083] Specifically, see Figure 2 The diagram shows a master node power distribution module 200. This master node power distribution module 200 includes a first input interface 1, a second interface 2, a first output interface 3, a second output interface 4, a third output interface 5, ..., an (N-2)th output interface N. The first input interface 1 is connected to a DC-DC converter; the second interface 2 is connected to a battery; the first output interface 3, the second output interface 4, the third output interface 5, ..., the (N-2)th output interface N are connected to a slave node power distribution module 300 and a second device to be powered.

[0084] During operation, the main node power distribution module 200 supplies power to the second equipment to be distributed and the main node power distribution module 300 using the first input interface 1.

[0085] The second interface 2 mentioned above is a bidirectional interface, that is, the main node power distribution module 200 can charge the battery while driving, and can use the battery to power the second power distribution equipment and the main node power distribution module 300 when the vehicle starts or the power supply 400 fails.

[0086] The aforementioned batteries can be 12V, 24V, or 48V batteries.

[0087] In some embodiments of this utility model, the power distribution system 100 further includes an on-board charger, and the master node power distribution module 200 is adapted to connect to the power supply 400 via the on-board charger.

[0088] In some embodiments of this utility model, the first device to be distributed 500 and the second device to be distributed include safety devices and non-safety loads on the vehicle. The safety devices include braking systems, steering systems, driving assistance systems, etc.

[0089] In some embodiments of this utility model, the master node power distribution module 200 includes the vehicle's rear area controller.

[0090] Specifically, the vehicle includes a front area controller, a rear area controller, a left area controller, and a right area controller.

[0091] The aforementioned rear area controller is an area controller that controls the equipment at the rear of the vehicle. The equipment at the rear of the vehicle includes safety devices and non-safety loads, such as lights, tailgate, and radar.

[0092] Similarly, the front area controller controls the equipment at the front of the vehicle, the left area controller controls the equipment on the left side of the vehicle, and the right area controller controls the equipment on the right side of the vehicle.

[0093] By setting the vehicle's rear area controller as the main node power distribution module 200 in the power distribution system 100, the core power distribution module of the vehicle can be located at the rear of the vehicle, thereby improving vehicle safety. For example, assuming a car accident occurs, the rear area controller, being located at the rear of the vehicle, has the lowest probability of damage. In this case, even if the vehicle's left area controller is damaged, the rear and front area controllers can still operate under the power supply of the rear area controller. In other words, by setting the main node power distribution module 200 as the vehicle's rear area controller, safety redundancy functions can be backed up to the rear domain. While reducing some wiring diameter, it ensures the normal operation of basic functions during a collision, providing more room for cost reduction, safety performance, and styling design.

[0094] In some embodiments of this utility model, the number of master node power distribution modules 200 is one, which includes the vehicle's rear area controller, and the number of slave node power distribution modules 300 is at least two.

[0095] The following is combined with Figure 3 The specific embodiment shown will be described below. In this specific embodiment, there is one master node power distribution module 200 and two slave node power distribution modules 300.

[0096] Specifically, in Figure 3 In the specific embodiment shown, 111 is a first DC-DC converter, 112 is a first disconnecting switch, 113 is a rear area controller, 114 is a second disconnecting switch, 115 is a third disconnecting switch, 116 is a fourth disconnecting switch, 117 is a right area controller, 118 is a left area controller, 119 is a first battery, and 120 is a second battery.

[0097] The master node power distribution module 200 includes a rear area controller 113, a slave node power distribution module 300 includes a left area controller 118, and another slave node power distribution module 300 includes a right area controller 117.

[0098] The aforementioned left area controller 118 and right area controller 117 are area controllers that control the equipment on the left and right sides of the vehicle, respectively. The aforementioned rear area controller 113, left area controller 118, and right area controller 117 both control and supply power to the equipment. The aforementioned first disconnect switch 112 is the first disconnect device, the aforementioned second disconnect switch 114 is the second disconnect device, and the aforementioned third disconnect switch 115 and fourth disconnect switch 116 are the third disconnect devices.

[0099] The first disconnect switch 112, the rear area controller 113, and the second disconnect switch 114 form a master node power distribution module 200; the third disconnect switch 115 and the right area controller 117 form a slave node power distribution module 300; and the fourth disconnect switch 116 and the left area controller 118 form a slave node power distribution module 300.

[0100] At this time, the first power distribution equipment 500 includes equipment on the left and right sides of the vehicle, and the second power distribution equipment includes equipment at the rear of the vehicle.

[0101] When the power supply 400 is working, the rear area controller 113 uses the power provided by the power supply 400 to power the equipment at the rear of the vehicle. At the same time, it also needs to provide the power provided by the power supply 400 to the left area controller 118 and the right area controller 117, so that the left area controller 118 uses the power provided by the power supply 400 to power the equipment on the left side of the vehicle, and the right area controller 117 uses the power provided by the power supply 400 to power the equipment on the right side of the vehicle.

[0102] When the power supply 400 is not working or the vehicle has just been powered on, the right area controller 117 uses the first battery 119 to power the equipment on the right side of the vehicle, and the left area controller 118 uses the second battery 120 to power the equipment on the left side of the vehicle.

[0103] Next, let's combine... Figure 4 The specific embodiment shown will be described below. In this specific embodiment, there is one master node power distribution module 200 and three slave node power distribution modules 300.

[0104] The master node power distribution module 200 includes a rear area controller 113, the first slave node power distribution module 300 includes a left area controller 118, the second slave node power distribution module 300 includes a right area controller 117, and the third slave node power distribution module 300 includes a front area controller 121.

[0105] exist Figure 4In the specific embodiment shown, a front area controller 121 is also included, which is a slave node power distribution module 300. At this time, the first device to be powered 500 also includes equipment at the front of the vehicle, and the rear area controller 113 also needs to provide power from the power source 400 to the front area controller 121 so that the front area controller 121 can use the power source 400 to power the equipment at the front of the vehicle.

[0106] Next, let's combine... Figure 5 The specific embodiment shown will be described below. In this specific embodiment, there is one master node power distribution module 200 and three slave node power distribution modules 300.

[0107] The master node power distribution module 200 includes a rear area controller 113, the first slave node power distribution module 300 includes a left area controller 118, the second slave node power distribution module 300 includes a right area controller 117, and the third slave node power distribution module 300 includes a front area controller 121.

[0108] exist Figure 5 The specific embodiment shown also includes a splitter 126, a fifth disconnect switch 122, a third battery 125, a first safety device 127, a first unsafe load 128, a second safety device 129, a second unsafe load 130, a third safety device 131, a third unsafe load 132, a fourth safety device 133, and a fourth unsafe load 134.

[0109] Among them, the first safety device 127, the first unsafe load 128, the second safety device 129, the second unsafe load 130, the third safety device 131, and the third unsafe load 132 are the first equipment to be distributed 500, and the fourth safety device 133 and the fourth unsafe load 134 are the second equipment to be distributed.

[0110] When the vehicle starts or a power supply 400 fails, the right zone controller 117 controls the first battery 119 to supply power to the first safety device 127, the left zone controller 118 controls the second battery 120 to supply power to the second safety device 129, and the front zone controller 121 and the third battery 125 supply power to the third safety device 131. This ensures that the safety devices function normally in the event of a power outage or short circuit, guaranteeing the safety of the vehicle and passengers under extreme conditions.

[0111] When the vehicle is in normal operation, the right area controller 117 uses the power of the power supply 400 to charge the first battery 119, the left area controller 118 uses the power of the power supply 400 to charge the second battery 120, and the front area controller 121 uses the power of the power supply 400 to charge the third battery 125.

[0112] In some embodiments of this utility model, there are two master node power distribution modules 200 and two slave node power distribution modules 300.

[0115] In this specific embodiment, the fifth disconnect switch 122, the front area controller 121 and the sixth disconnect switch 123 form a main node power distribution module 200, and the first disconnect switch 112, the rear area controller 113 and the second disconnect switch 114 form a main node power distribution module 200.

[0116] In other words, in this specific embodiment, there are two master node power distribution modules 200. When one of the master node power distribution modules 200 fails, the slave node power distribution module 300 can still use the other master node power distribution module 200 to share power to the first equipment to be distributed 500, thereby achieving redundant power distribution. In the event of a failure, the main driving functions are not degraded.

[0117] Next, let's combine... Figure 7 The specific embodiment shown will be described below. In this specific embodiment, there are two master node power distribution modules 200 and two slave node power distribution modules 300. One master node power distribution module 200 includes a rear area controller 113, and the other master node power distribution module 200 includes a front area controller 121. One slave node power distribution module 300 includes a left area controller 118, and the other slave node power distribution module 300 includes a right area controller 117.

[0118] exist Figure 7 In the specific embodiment shown, a fourth battery 135 is also included. In this case, the rear area controller 113 can charge the fourth battery 135 when the vehicle is driving normally, and use the fourth battery 135 to power the fourth safety device 133 and the fourth non-safety load 134 when the vehicle starts or the power supply 400 fails.

[0119] In summary, the power distribution system of this embodiment includes at least one master node power distribution module and at least two slave node power distribution modules. The master node power distribution module is adapted to connect to a power source, and the slave node power distribution modules are connected to the master node power distribution module and adapted to connect to a first device to be distributed. Therefore, by setting parallel slave node power distribution modules, power distribution can be achieved with lower system weight and cost.
