[0048] The above-mentioned conduction state may refer to a control switch or relay being in a closed state, allowing power to flow from one port to another port.

[0058] In an optional embodiment, a main positive relay and a main negative relay are provided between the battery and the load, and the control end of the relay is precisely connected to the power supply unit and the control switch group, so that power transmission can be effectively managed and controlled under normal and abnormal conditions. In this way, the system can automatically switch to a backup control and power supply path in the event of a controller or power supply unit failure, ensuring the continuity and stability of the battery pack supplying power to the load, thereby greatly improving the reliability and safety of the aircraft power supply system.

[0062] In an optional embodiment, by introducing a main positive control switch and a main negative control switch respectively, redundant management of the control signals of the main positive relay and the main negative relay is achieved. In this way, when a control switch fails, the system can still control the state of the relay through another normally working control switch, maintain the continuity of the battery pack supplying power to the load, and thus improve the stability of the aircraft power supply system.

[0066] In an optional embodiment, by constructing a battery unit including a power supply, a first diode and a second diode, not only is the current from the power supply unit to the relay control terminal ensured to flow in one direction, but also circuit failures that may be caused by reverse currents are avoided.

When one of the power supply units fails or fails, the system can still maintain power supply to the battery pack and the load through the normally working power supply unit and the corresponding diode without being affected by the failed unit, and the circuit troubleshooting and maintenance process is simplified, thereby improving the safety and stability of the entire power supply system.

[0069] The above-mentioned preset voltage may refer to a preset voltage threshold, and the preset voltage may be used to evaluate whether the output voltage of the power supply unit is high enough to meet the requirements for normal operation of the system.

[0070] In an optional embodiment, by setting a preset voltage and limiting the power supply voltage to be less than the preset voltage, the system can identify and isolate inefficient or faulty power supply units, avoid failure of key equipment due to insufficient voltage, and trigger automatic switching of redundant power supply units to ensure that even under harsh conditions, such as voltage drops caused by aging of the power supply unit, temperature changes, or external interference, the system can still supply power normally to maintain stable operation of the aircraft.

[0075] In an optional embodiment, when receiving the power supply instruction, the control switch group in the power supply control system is controlled to be in the first conduction state, at which time the resistance of the control switch is almost zero, and power can be efficiently and unimpededly transmitted. This state switching achieved by the control device by sending the power supply instruction can ensure smooth power transmission, thereby ensuring the smooth operation of the aircraft power supply system.

[0076] Step S304: Control multiple power supply units to supply power to at least one battery pack based on the first conduction state.

[0077] In an optional embodiment, when the aircraft is started and ready to take off, the control device will send a power supply instruction to multiple controllers at the same time, instructing them to prepare power supply for the flight mission; in response to this instruction, the multiple controllers will activate their respective control switch groups to put them in the first conduction state; after entering the first conduction state, the controller will connect the circuit path between the power supply unit and the relay group through the control switch group. At this time, the multiple power supplies will respectively supply power to the relays of the multiple battery packs through the multiple diodes, while maintaining the power supply of the relay group, ensuring that the battery pack continues to supply power to the load of the aircraft. The above process can ensure that at least one battery pack is supplied with power by putting the control switch group in the first conduction state, thereby providing continuous power for the aircraft.

[0078] In an optional embodiment, when the vehicle is started and ready to drive, or when the vehicle is not started and only the air conditioner and other power-requiring devices in the vehicle are turned on, the control device will send power supply instructions to multiple controllers at the same time, instructing them to prepare power supply for the driving task; in response to this instruction, the multiple controllers will activate their respective control switch groups to put them in the first conduction state; after entering the first conduction state, the controller will connect the circuit path between the power supply unit and the relay group through the control switch group. At this time, the multiple power supplies will respectively supply power to the relays of the multiple battery packs through the multiple diodes, while maintaining the power supply of the relay group, ensuring that the battery pack continues to supply power to the vehicle's load. The above process can ensure that at least one battery pack is supplied with power by putting the control switch group in the first conduction state, thereby providing continuous power to the vehicle.

[0079] Optionally, the method also includes: in response to receiving a first fault instruction of any controller among the multiple controllers, controlling at least one control switch group of a target controller other than any controller among the multiple controllers to be in a second conduction state; and controlling multiple power supply units to supply power to at least one battery pack based on the second conduction state.

[0080] The above-mentioned first fault instruction may refer to a signal or instruction sent to other controllers in the system in the power supply control system when the controller detects a fault in itself or other key components in the system. The functions of the first fault instruction may include but are not limited to fault alarms, guiding the system to adopt corresponding fault resolution measures to ensure the continuity of power supply, etc.

[0081] The above-mentioned second conduction state may mean that after receiving the first fault instruction, the target controller is in a state allowing current to pass. The type of the second conduction state may include but is not limited to a fully conduction state, a partially conduction state, and a soft conduction state, etc. The specific second conduction state needs to be determined according to the power demand and is not limited here. The function of the first conduction state may include but is not limited to starting power transmission, system redundancy and fault switching, and load management, etc.

[0082] In an optional embodiment, after the aircraft starts and begins to perform a mission, it is assumed that the controller 1 detects that the power supply unit 1 or itself fails, and then sends a first fault instruction to the controller 2; after receiving this instruction, the controller 2 immediately responds and adjusts the control switch group controlled by it to the second conduction state, that is, the fully conduction state. This means that the controller 2 will close its main positive control switch 2_1 and the main negative control switch 2_1, while maintaining the closed state of the main positive control switch 2_2 and the main negative control switch 2_2, to ensure that the lines where D3 and D4 are located are not affected by the power supply of the battery pack 1 and the battery pack 2. In addition, the controller 2 will increase the control strength of the battery pack 1 and the battery pack 2, and through the lines where D1 and D2 are located, even if the power supply unit 1 fails, the power supply unit 2 can continue to supply power to the battery pack to maintain the normal operation of the aircraft. In this process, through the coordinated processing of the first fault instruction and the second conduction state, it is ensured that when the power supply control system faces a fault, it can continue to supply power through the unaffected components through a timely fault detection and response mechanism to avoid interruption of the flight mission.

[0083] Optionally, the method further includes: in response to receiving a second fault instruction of any power supply unit among the multiple power supply units, controlling a target power supply unit other than any power supply unit among the multiple power supply units to power at least one battery pack based on the first conduction state.

[0084] The above-mentioned second fault instruction may refer to an emergency signal sent to other unaffected power supply units and controllers in the system when one of the multiple power supply units in the system detects a fault or abnormality in itself and cannot supply power normally. The second fault instruction may be used for power supply failure notification, prompting the system to take measures, and adjusting the power supply strategy to maintain the stability of the power supply of the entire system.

[0085] In an optional embodiment, when any one of the multiple power supply units issues a second fault instruction due to its own fault, the power supply control system controls the non-faulty power supply units among the multiple power supply units to supply power to the battery pack based on the first conduction state after receiving the second fault instruction. This immediate fault response and redundant switching can effectively avoid power interruptions in the aircraft due to power supply unit failure, thereby ensuring the continuity of the flight mission and the safety of the aircraft.

[0086] Optionally, the method also includes: in response to receiving a first fault instruction of any controller among the multiple controllers and receiving a second fault instruction of any power supply unit among the multiple power supply units, controlling at least one control switch group of a target controller other than any controller among the multiple controllers to be in a second conduction state; based on the second conduction state, controlling the target power supply unit other than any power supply unit among the multiple power supply units to power at least one battery pack.

[0087] In an optional embodiment, in the power supply control system, assuming that a certain controller fails and sends a first fault instruction, and at the same time, a certain power supply unit also fails and sends a second fault instruction, at this time, the power supply control system responds to the received first fault instruction and second fault instruction, sets the control switch group in the target controller to the second conduction state, maintains power supply to the battery pack through the unaffected controller and power supply unit, and ensures the stable operation of the aircraft. The above process not only avoids the flight mission being affected by power outages, but also maximizes the system's tolerance and response efficiency to faults.

[0088] In an optional embodiment, Figure 4 is a flow chart of a low voltage power supply control method according to an embodiment of the present invention. Figure 4 As shown, first, power supply starts, and the low-voltage power supply 1 / 2 outputs to the outside at the same time; D2 / D4 supplies power to the main negative relay 1 / 2 at the same time, and D1 / D3 supplies power to the main positive relay 1 / 2 at the same time; at this time, it is determined whether D2 or D4 fails. If so, D4 or D2 supplies power alone, if not, D2 / D4 supplies power at the same time; similarly, it is determined whether D1 or D3 fails. If so, D3 or D1 supplies power alone, if not, D1 / D3 supplies power at the same time, and finally the process ends.
