[0037] The present application provides a power distribution system, which can be used in a vehicle. The power distribution system may include a main power supply, a central power distribution unit, and multiple power distribution areas, wherein the main power supply is connected to the central power distribution unit, the central power distribution unit is connected to the multiple power distribution areas respectively, and the multiple power distribution areas are not connected to each other. Figure 1 As shown, Figure 1It is a structural schematic diagram of a power distribution system provided in an embodiment of the present application, wherein the power distribution system includes a main power supply 11, a central distribution unit 12, and multiple distribution areas 13. The main power supply 11 is connected to the central distribution unit 12, and the central distribution unit 12 is respectively connected to the multiple distribution areas 13, and the multiple distribution areas 13 are not connected to each other.

[0038] The central power distribution unit is used to control the main power supply to supply power to each distribution area. Each distribution area includes at least one distribution unit, and each distribution unit is used to distribute current to at least one load of the vehicle. The main power supply may include but is not limited to a direct current converter (DCDC).

[0039] The embodiment of the present application uses a power distribution system in which each power distribution area is not connected to each other, which can not only realize regional power distribution for vehicles, but also realize independent power supply for each power distribution area.

[0040] In one embodiment, the power distribution system further includes at least one battery, each battery being connected to a central power distribution unit; the central power distribution unit is further configured to disconnect the main power supply when a short circuit or disconnection occurs in the main power supply, and control at least one battery to supply power to each power distribution area. In some embodiments, any battery may include, but is not limited to, a 12V battery including a low-voltage battery management system.

[0041] In the embodiment of the present application, the central distribution unit disconnects from the main power supply when a short circuit or a break occurs in the main power supply, and controls at least one battery to supply power to each distribution area. This can avoid the situation where the vehicle cannot operate when a short circuit or a break occurs in the main power supply, and help improve the safety of the vehicle.

[0042] In one embodiment, the vehicle includes at least one load, each load being connected to at least one of the plurality of power distribution areas. In some embodiments, the at least one load refers to a component in at least one functional domain of the vehicle, the at least one functional domain including one or more of a body domain, a power domain, and a chassis domain.

[0043] Among them, the body domain can include any equipment installed on the body, such as: lights, doors, rearview mirrors, windows, seats, wipers, etc. The chassis domain can include the transmission system, running system, steering system and braking system, and the chassis domain includes: clutch, transmission, axle, wheel, brake, etc. The power domain can include the electronic control system, battery management system (Battery Management System, BMS), inverter, on-board charger (On-board charger, OBC), etc. The power domain includes: power battery, inverter, OBC, drive motor, motor controller, etc.

[0044] For any load, the distance between at least one distribution area connected to any load and any load is smaller than the distance between any load and other distribution areas among multiple distribution areas. In other words, for any load, when selecting a distribution area connected to any load, select the distribution area closest to any load. In this way, on the basis of independent power supply in each distribution area, power distribution can be achieved nearby to reduce wiring.

[0045] The present application provides a power distribution system that can be applied to vehicles. In certain embodiments, the power distribution system can also be applied to any type of mobile terminal equipment including but not limited to ships, airplanes, trains, etc.

[0046] The present application is described below using a vehicle application scenario as an example with reference to the accompanying drawings.

[0047] See also Figure 2 , Figure 2 A structural diagram of another power distribution system provided in an embodiment of the present application is as follows: Figure 2 As shown, the power distribution system includes a main power supply 21, a central distribution unit 22, a first distribution area 23, a second distribution area 24, a third distribution area 25, a fourth distribution area 26, a first battery 271 (such as battery 01) and a second battery 272 (such as battery 02).

[0048] The first power distribution area 23 includes a first power distribution unit 231, a second power distribution unit 232 and a third power distribution unit 233, the second power distribution area 24 includes a fourth power distribution unit 241 and a fifth power distribution unit 242, the third power distribution area 25 includes a sixth power distribution unit 251, a seventh power distribution unit 252 and an eighth power distribution unit 253, and the fourth power distribution area 26 includes a ninth power distribution unit 261 and a tenth power distribution unit 262. A short circuit or a break in any of the power distribution units will cause a short circuit or a break in the power distribution area where any of the power distribution units is located.

[0049] The main power supply 21 is connected to the central distribution unit 22, and the central distribution unit 22 is respectively connected to the first distribution area 23, the second distribution area 24, the third distribution area 25 and the fourth distribution area 26, the first battery 271 (such as battery 01) and the second battery 272 (such as battery 02) are respectively connected to the central distribution unit 22, and the first distribution area 23, the second distribution area 24, the third distribution area 25 and the fourth distribution area 26 are not connected to each other.

[0050] The central power distribution unit 22 is used to control the main power supply 21 to supply power to the first power distribution area 23 , the second power distribution area 24 , the third power distribution area 25 , and the fourth power distribution area 26 .

[0051] The central power distribution unit 22 can also be used to disconnect the main power supply 21 when a short circuit or open circuit occurs in the main power supply 21, and control at least one of the first battery 271 (such as battery 01) and the second battery 272 (such as battery 02) to supply power to the first distribution area 23, the second distribution area 24, the third distribution area 25, and the fourth distribution area 26.

[0052] The central power distribution unit 22 can also be used to disconnect any power distribution area when a short circuit or a short circuit occurs in any power distribution area. Since the first power distribution area 23, the second power distribution area 24, the third power distribution area 23 and the fourth power distribution area 24 are not connected to each other, the central power distribution unit 22 can stop supplying power to any power distribution area where a short circuit or a short circuit occurs by disconnecting the connection with any power distribution area when a short circuit or a short circuit occurs in any power distribution area, without affecting the power supply of other power distribution areas.

[0053] The vehicle includes at least one load ( Figure 2 (not shown), each load is connected to at least one distribution area among the multiple distribution areas.

[0054] For any load, a distance between at least one distribution area connected to any load and any load is smaller than a distance between any load and other distribution areas among the multiple distribution areas.

[0055] For example, assuming that the distance between a load of the vehicle and the first power distribution area 23 is 20 cm, and the distance between the load and the third power distribution area 25 is 30 cm, the load can be connected to the first power distribution area.

[0056] When any load is connected to multiple (2 or more) distribution areas, the distance between the multiple distribution areas and any load is smaller than the distance between any load and other distribution areas.

[0057] For example, assuming that a load of the vehicle is 20 cm away from the first distribution area 23, 30 cm away from the third distribution area 25, 80 cm away from the second distribution area 24, and 1 m away from the fourth distribution area 26, the load can be connected to the first distribution area 23 and the third distribution area 25 respectively.

[0058] When any load is connected to multiple distribution areas, current can be distributed to any load through one distribution area connected to any load. When a short circuit or open circuit occurs in one distribution area connected to any load, current can be distributed to any load through another distribution area connected to any load. In this way, it is possible to avoid the situation where the load cannot operate when a short circuit or open circuit occurs in one distribution area connected to the load, thereby improving the flexibility of power supply to the vehicle load.

The main power supply 31 is connected to the central distribution unit 32; the central distribution unit 32 is respectively connected to the multiple distribution areas 33, and every two distribution areas in the multiple distribution areas 33 are connected through an isolation unit.

[0060] Among them, the central distribution unit is used to control the main power supply to supply power to each distribution area.

[0061] The power distribution system also includes at least one battery, and each battery is connected to a central power distribution unit; the central power distribution unit is also used to disconnect the main power supply when a short circuit or open circuit occurs in the main power supply, and control at least one battery to supply power to each distribution area.

[0062] Any isolation unit among the multiple isolation units is used to disconnect two power distribution areas connected to any isolation unit when a short circuit or a break occurs in any power distribution area connected to any isolation unit.

[0063] The embodiment of the present application introduces multiple isolation units in the power distribution system so that when a short circuit or a short circuit occurs in any distribution area connected to any isolation unit, the connection between two distribution areas connected to any isolation unit is disconnected. This can prevent other distribution areas from being affected by the short circuit or the short circuit in any distribution area, thereby achieving the independence of each distribution area.

[0080] See also Figure 7 , Figure 7 is a flow chart of a power distribution method provided in an embodiment of the present application, such as Figure 7 As shown, the power distribution method is applied to a power distribution system, the power distribution system includes a central power distribution unit, multiple power distribution areas and a main power supply, the multiple power distribution areas are not connected to each other, wherein the method may at least include the following steps:

[0081] S70: The power distribution system can control the main power supply to supply power to each distribution area through the central power distribution unit.

[0082] In the embodiment of the present application, when the power distribution system controls the main power supply to supply power to each power distribution area through the central power distribution unit, any one or more of the following steps may be performed:

[0083] S701: When the power distribution system detects a short circuit or open circuit in any power distribution area through the central power distribution unit, the power distribution system can disconnect the central power distribution unit from any power distribution area and control the main power supply to supply power to other power distribution areas among the multiple power distribution areas.

[0084] The power distribution system also includes at least one battery. S702: When the power distribution system detects that the main power supply is short-circuited or disconnected through the central power distribution unit, it can disconnect the central power distribution unit from the main power supply and control at least one battery to supply power to each distribution area.

[0085] In this way, the battery can be controlled to supply power to the vehicle when the main power supply is short-circuited or disconnected, which helps to improve the safety of the vehicle.

[0086] by Figure 2 For example, assuming that the power distribution system detects that the main power supply 21 is short-circuited or open-circuited through the central distribution unit 22, the central distribution unit 22 can disconnect the main power supply 21 and control the first battery 271 and / or the second battery 272 to supply power to each distribution area.

[0087] In one embodiment, when the power distribution system detects through the central power distribution unit that any of the at least one battery is short-circuited or open-circuited, the power distribution system can disconnect the central power distribution unit from any battery.

[0088] by Figure 2 For example, assuming that the power distribution system detects through the central power distribution unit 22 that the first battery 271 is short-circuited or open-circuited, the connection between the central power distribution unit 22 and the first battery 271 can be disconnected.

[0089] S703: For any load of the vehicle, when the central distribution unit detects a short circuit or open circuit in any distribution area connected to any load, the distribution system disconnects the central distribution unit from any distribution area and sends a control instruction to another distribution area connected to any load, where the control instruction is used to instruct the other distribution area to distribute current to any load.

[0090] By controlling other distribution areas to distribute current to any load when a short circuit or open circuit occurs in the distribution area connected to the load, the flexibility and effectiveness of each distribution area of ​​the vehicle in supplying power to each load can be improved, ensuring that any load can continue to operate normally and preventing any load from being affected by each distribution area, which helps to further improve the safety and performance of the vehicle.

[0091] The embodiment of the present application controls the main power supply to supply power to each unconnected distribution area through the central distribution unit, so that each distribution area can independently supply power to the vehicle, thereby improving the safety and effectiveness of the vehicle's power supply.

[0092] See also Figure 8 , Figure 8 is a flow chart of another power distribution method provided in an embodiment of the present application, such as Figure 8 As shown, the power distribution method is applied to a power distribution system, the power distribution system includes a central power distribution unit, multiple power distribution areas, a main power supply and multiple isolation units, wherein the method may at least include the following steps:

[0093] S801: interact with any isolation unit through the central distribution unit to control the connection status of two distribution areas connected to any isolation unit.

[0094] S802: Control the main power supply to supply power to each power distribution area.

[0095] In one embodiment, when the power distribution system detects a short circuit or open circuit in any distribution area through the central distribution unit, the power distribution system can disconnect the central distribution unit from any distribution area and send a control instruction to two isolation units connected to any distribution area. The control instruction is used to instruct any of the two isolation units to disconnect the two distribution areas connected to any isolation unit.

[0096] by Figure 4 For example, assuming that the power distribution system detects that a short circuit or open circuit occurs in the first distribution area 43 through the central distribution unit 42, the central distribution unit 42 can be disconnected from the first distribution area 43, and a control instruction can be sent to the first isolation unit 471 and the second isolation unit 472 connected to the first distribution area 43 to control the first isolation unit 471 and the second isolation unit 472 to disconnect the two distribution areas connected to any isolation unit, thereby isolating the second distribution area 44 and the third distribution area 45 from the first distribution area 43, and preventing the second distribution area 44 and the third distribution area 45 from being affected by the short circuit or open circuit of the first distribution area 43.

[0097] In one embodiment, the power distribution system also includes at least one battery. When the power distribution system detects that the main power supply is short-circuited or open-circuited through the central distribution unit, the power distribution system can disconnect the central distribution unit from the main power supply and control at least one battery to supply power to each distribution area.

[0098] When the power distribution system detects through the central power distribution unit that any of the at least one battery is short-circuited or open-circuited, the power distribution system can disconnect the central power distribution unit from any of the batteries.

[0099] The vehicle includes at least one load. For any load, when a short circuit or open circuit is detected in any distribution area connected to any load through the central distribution unit, the connection between the central distribution unit and any distribution area can be disconnected, and a control instruction can be sent to another distribution area connected to any load, and the control instruction is used to instruct the other distribution area to distribute current to any load.

[0100] by Figure 5 For example, assuming that when a short circuit or open circuit is detected in the first distribution area 53 connected to any load through the central distribution unit 52, the connection between the central distribution unit 52 and the first distribution area 53 can be disconnected, and a control instruction can be sent to the second distribution area 54 connected to any load to control the second distribution area 54 to distribute current to any load.

[0101] This method can improve the flexibility and effectiveness of each distribution area of ​​the vehicle in supplying power to each load, ensure that any load can continue to operate normally, avoid any load being affected by each distribution area, meet the needs of distribution isolation and distribution redundancy, and help further improve the safety and performance of the vehicle.

[0102] The embodiment of the present application interacts with any isolation unit through the central distribution unit to control the connection status of two distribution areas connected to any isolation unit, and controls the main power supply to supply power to each distribution area. This can ensure that when a short circuit or open circuit occurs in any distribution area, other distribution areas are not affected, which helps to improve the flexibility and safety of power supply to the vehicle.
