[0025] On the first aspect, the embodiments of the present application provide an integrated intelligent power distribution management system for realizing intelligent power distribution of an all-electric transmission platform, that is, realizing unified power distribution management of various electrical equipment, and having a certain fault isolation capability and good reliability.

[0026] In one embodiment, referring to Figure 1 , Figure 1 This is a schematic diagram of the structure of the integrated intelligent power distribution management system for this application. Figure 1 As shown, the integrated intelligent power distribution management system includes: an integrated control terminal, a chassis controller, a low-voltage distribution box, and at least one high-voltage distribution box. In actual applications, the high-voltage distribution box generally includes multiple ones. In this application, the integrated control terminal, the chassis controller, the low-voltage distribution box, and the high-voltage distribution box communicate through CAN bus communication. The integrated intelligent power distribution management system adopts a distributed power distribution topology and uses the CAN bus network to realize distributed power distribution, so that the fault section can be isolated when a fault occurs, and when the CAN bus network communication fails, the power distribution state is maintained autonomously.

[0027] For the integrated control terminal, the integrated control terminal is equipped with a full launch platform power distribution operation interface, and a multi-mode power distribution state is preset, so that according to the current working conditions, the integrated control terminal automatically sends a power distribution instruction to the chassis controller, and then the chassis controller controls the high-voltage distribution box to realize high-voltage circuit power distribution, or according to the current working conditions, the integrated control terminal directly controls the low-voltage distribution box to realize low-voltage circuit power distribution. Specifically, according to the chassis working conditions of the all-electric launch platform, the integrated control terminal sends a power distribution instruction to the chassis controller, and the chassis controller controls the high-voltage distribution box to realize high-voltage circuit power distribution, or the integrated control terminal sends a power distribution instruction to the low-voltage distribution box, and directly controls the low-voltage distribution box to realize low-voltage circuit power distribution.

[0028] The multi-mode power distribution status in this application includes traveling mode, centralized control unmanned mode, independent manned mode, mains power sleep mode, no mains power sleep mode, and wake-up mode.

[0029] Furthermore, the integrated control terminal runs a power supply and distribution domain control APP (Application), which is used to control the high-voltage distribution box and the low-voltage distribution box, and display the power distribution status and fault information. Furthermore, the integrated control terminal is equipped with multiple CAN (Controller Area Network) interfaces, which are used to form a CAN bus network for power supply and distribution with the chassis controller and the high-voltage distribution box.

[0030] See also Figure 2As shown, it is a structural schematic diagram of the integrated control terminal, on which a display screen is arranged, and a plurality of function buttons, such as an emergency stop button, are arranged below the display screen. A touch pen placement slot is arranged on the right side of the display screen, and touch operations can be performed on the display screen with the touch pen.

[0031] In this application, the chassis controller is used to receive the power distribution instructions sent by the integrated control terminal, and send the power distribution instructions to the high-voltage distribution box in combination with the current chassis operating conditions to control the on and off of the corresponding high-voltage distribution circuit.

[0032] In this application, the high-voltage distribution box adopts a modular design, and each high-voltage distribution box has the same electrical interface and installation interface. The high-voltage distribution box is arranged near the power-consuming equipment; the high-voltage distribution box is used to collect the status of the distribution circuit and upload it to the integrated control terminal through the CAN bus. The high-voltage distribution box adopts a modular design, and each high-voltage distribution box has the same function and can be disassembled separately, which is convenient for maintenance.

[0033] In this application, each high-voltage distribution box is equipped with a high-voltage DC input interface, a low-voltage power supply interface, a CAN communication interface, and multiple high-voltage distribution output interfaces, and the contactor on-off state, voltage, and current of each high-voltage distribution output interface can be detected. The high-voltage distribution box receives the power distribution command from the integrated control terminal or chassis controller to control the on-off of the corresponding contactor, and can be manually controlled when the CAN bus network fails, and autonomously maintains the current power distribution state.

[0034] In this application, the low-voltage distribution box is used to realize the power distribution management of low-voltage electrical equipment. The electrical input of the low-voltage distribution box is a DC power supply or a battery, and the output is each electrical equipment, and the low-voltage distribution box has a CAN communication interface. For example, the low-voltage distribution box realizes the power distribution management of 28V low-voltage electrical equipment, and the electrical input is a 28V DC power supply or a battery, and the output is each 28V electrical equipment.

[0035] The low-voltage distribution box is used to form a CAN bus network with the integrated control terminal through the CAN communication interface, and receive distribution instructions to perform distribution management functions and upload status information. The low-voltage distribution box and the high-voltage distribution box achieve high and low voltage electrical isolation to reduce crosstalk.

[0036] The intelligent power distribution management system of the present application adopts a distributed power distribution topology and uses the CAN bus network to realize distributed power distribution, replacing the distribution lines of varying lengths output by a unified distribution box, reducing the number of distribution lines and saving space; on the other hand, the power distribution system adopts a modular design approach, which reduces the coupling between the functional modules and facilitates the subsequent expansion of power distribution nodes and functions.

[0037] The intelligent power distribution management system of the present application includes an integrated control terminal, a chassis controller, a high-voltage distribution box, and a low-voltage distribution box, and the integrated control terminal, the chassis controller, the high-voltage distribution box, and the low-voltage distribution box communicate through the CAN bus network. The integrated control terminal sends CAN command messages to the chassis controller and the high-voltage distribution box through a preset mode according to the current use conditions to control the on and off of the corresponding distribution circuit. The integrated intelligent power distribution management system adopts a distributed power distribution topology. The high-voltage distribution box is set near the power-consuming equipment. The distribution line can be laid in the shortest possible path, which significantly reduces the cable length. The integrated intelligent power distribution management system has the ability to isolate faults. When a high-voltage distribution box fails, the fault isolation can be achieved by cutting off the DC bus switch at the fault location without affecting the remaining high-voltage distribution boxes. It also has a certain fault tolerance capability. When the CAN bus fails, the power distribution state is maintained autonomously.

[0038] The integrated intelligent power distribution management system of the embodiment of the present application realizes centralized control and management of two power supply and distribution systems of different voltage levels and power levels through an integrated control terminal, thereby improving the stability of the power supply and distribution system.

A distributed power distribution topology is adopted, and the high-voltage distribution box is arranged near the power-consuming equipment. The distribution line can be laid along the shortest possible path, significantly reducing the cable length. The high-voltage distribution box adopts a modular design with the same functions. After a fault occurs, the corresponding module can be disconnected to achieve fault isolation and avoid affecting the normal high-voltage distribution box.
