Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV start-up and ground power supply device and its usage method. Background Technology

[0002] In the field of maintenance and deployment support for UAVs, especially medium and large fixed-wing UAVs, the core links are the main engine start-up, ground power-on inspection of airborne systems, and providing emergency power supply. The development of this technology field mainly revolves around the evolution of power supply methods. For a long time, the AC-DC ground support solution relying on the fixed AC power grid has been the mainstream and mature technology path. This solution is usually powered by the ground AC power grid, and the AC mains power is converted into DC power that meets the requirements of UAVs through a high-power AC-DC converter vehicle, and then connected to the UAV through a cable.

[0003] Existing technical solutions typically include the following parts: AC input port: Connects to the industrial AC power grid; AC-DC converter main unit: It typically contains an EMI filter, rectifier bridge, PFC boost circuit and high-frequency DC-DC isolation converter module, which is responsible for efficiently and stably converting high-voltage AC power into low-voltage DC power. Output interface and control unit: Provides a DC output socket that conforms to UAV interface standards, and integrates voltage and current display and on / off control switch; Connecting cable: Used to connect the power supply vehicle to the drone.

[0004] The working principle of this solution is as follows: After the AC-DC conversion and voltage regulation are completed by the AC-DC conversion main unit, the mains power continuously provides ground power to the drone through the cable. When the start command is issued, the power supply must be able to withstand the instantaneous ultra-large current load caused by the drone engine start motor and maintain the bus voltage from collapsing. Although the technology is mature, this existing technical solution has the following inherent defects: Deployment flexibility is severely limited: its energy depends entirely on the fixed AC power grid, and the system cannot work independently at forward field airfields, disaster relief sites, or temporary take-off and landing points where there is no mains power, which greatly restricts the rapid deployment capability of UAVs.

[0005] There are risks related to power supply safety and compatibility. Voltage sag risk: The sudden load applied at the moment of engine start-up may cause a momentary voltage drop on the grid side or inside the power supply. If it exceeds the dynamic response range of the power supply, it may cause start-up failure or reset of airborne equipment. Electromagnetic interference risk: The high-frequency PWM switching action in the AC-DC converter unit will generate strong conducted and radiated electromagnetic interference, which may be coupled to sensitive airborne electronic equipment of the UAV through the power supply cable and affect the stability of flight control, communication and other systems. The system is complex and has a long support chain: it relies on large power vehicles or fixed power cabinets, requires specialized personnel for transportation, deployment and operation, and the entire support system is huge and cumbersome, lacking the ability for individual soldiers or small groups to carry it quickly. Summary of the Invention

[0006] The purpose of this invention is to provide a drone startup and ground power supply device and its usage method to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a drone start-up and ground power supply device, comprising: A high-power energy storage module, which is composed of multiple lithium-ion cells arranged in parallel and then in series, is used to provide a peak starting current of not less than 1200A. An intelligent battery management system, which is electrically connected to a high-power energy storage module, is used for monitoring, balancing, and thermal management of the battery cells. The safety protection and control unit is electrically connected to the intelligent battery management system and the high-power energy storage module. The safety protection and control unit integrates multiple protection circuits for overcharge, over-discharge, overcurrent, short circuit, over-temperature and pressure abnormality, which are directly driven by hardware. A high-reliability power interface is provided, which is connected to the output of a high-power energy storage module and is used to connect to a drone.

[0008] Preferably, the intelligent battery management system includes: The main control unit is responsible for logical judgment and system coordination; The data acquisition unit is used to monitor the voltage, total current and temperature of each battery cell in real time. An active balancing unit is used to transfer energy from battery cells with excessive voltage deviations during charging or resting. A thermal management unit is used to control a heating film integrated inside the battery pack to preheat the battery cells in a low-temperature environment.

[0009] Preferably, the intelligent battery management system further includes: A pressure detection unit is used to monitor the internal pressure of the battery pack and trigger protection when the pressure rises abnormally.

[0010] Preferred options also include: The human-machine interface is used to display power, voltage, current, temperature, alarm information and system status in real time.

[0011] Preferably, the high-reliability power interface uses a high-current aviation plug with low contact resistance and anti-misinsertion features, and the human-machine interface uses an industrial-grade touch screen.

[0012] This invention also provides a method for using a drone startup and ground power supply device, including the following specific steps: The specific usage steps are as follows: S1: Self-test and backup power. Perform an appearance and power-on self-test on the device to confirm that there are no faults and that the power is sufficient to meet the task requirements. S2: Reliable connection. When both the device and the drone are powered off, use a dedicated cable to reliably connect and lock their interfaces. S3: Ground power-on check, activate device output, power the UAV onboard system, monitor parameters, and assist in completing the ground function check before takeoff; S4: Critical Start. The device issues an engine start command, intelligently releases a massive instantaneous current to drive the starter motor, and the operator monitors the voltage curve to ensure a smooth and reliable start-up process. S5: Continuous protection and monitoring. After the engine starts successfully, the device switches to continuous power supply mode to support system operation until the drone is ready, and then safely disconnects the output. S6: Retraction and restoration, safely disconnect the connection, retract the cable, shut down the device, charge and maintain as needed, and restore the equipment to operational readiness.

[0013] Preferably, step S4 includes the following steps: S41: After completing the ground system check, prepare to start the engine; S42: Sends an engine start command to the UAV flight controller or ground control station; S43: At the moment the start command is triggered, the intelligent battery management system and safety protection and control unit inside the device work together to control the main contactor to close; S44: The high-power energy storage module releases a super-large current instantaneously, which drives the engine's starter motor through a cable; S45: The operator listens to the engine start-up sound and monitors the voltage curve of the start-up process through the device interface; S46: Once the engine successfully reaches idle speed, the start-up process ends, and the device load current will drop to the level required to maintain power supply.

[0014] Preferably, step S43 includes the following steps: Final status verification: After receiving the start command trigger signal, the intelligent battery management system performs a final verification of the real-time status of the high-power energy storage module. Once the protection unit is confirmed to be ready, the safety protection and control unit simultaneously confirms that all its hardware protection circuits are in a ready state and that no protection latch has been triggered. When the conditions are met, the intelligent battery management system sends a permission to close the circuit to the safety protection and control unit only when all state verifications are passed and the protection unit is ready. Upon receiving a signal indicating permission to close, the safety protection and control unit drives the main contactor to close, thus connecting the discharge circuit.

[0015] Preferably, the verification parameters include: whether the voltage of each battery cell is within a preset start-up voltage window, whether the battery core temperature is within a preset start-up temperature range, and whether the pressure detection unit reports normal pressure.

[0016] Preferably, the condition closure includes: The main control unit of the intelligent battery management system independently evaluates the verification results of each type of parameter in the final state verification and generates the corresponding evaluation state flag. The main control unit first checks the internal pressure safety assessment flag. If the flag indicates an abnormal pressure, it immediately triggers the highest priority fault latch and generates a final decision on prohibiting closure and pressure fault, skipping all subsequent assessments and logic, and directly enters the fault handling procedure. Under the premise that the pressure safety assessment flag is normal, the main control unit will take the cell voltage consistency assessment flag, the module temperature adaptability assessment flag, and the protection unit readiness confirmation signal from the safety protection and control unit as three parallel input conditions that must be met simultaneously. The main control unit generates the final instruction to allow closure only when all parallel input conditions continuously indicate normal and ready states within the preset decision time window, and sends the instruction to the safety protection and control unit.

[0017] The technical effects and advantages of this invention are as follows: (1) This invention innovates the AC-DC power supply that relies on the power grid into a high-energy-density battery direct drive system, which fundamentally solves the core defects of the existing technology such as limited deployment, electromagnetic interference and slow dynamic response. This enables the UAV support to completely get rid of the fixed power grid and achieve rapid deployment at the front line. At the same time, it provides pure DC and instantaneous high current, ensuring that the start-up is absolutely reliable and has no interference with the airborne equipment. (2) By integrating a multi-layer intelligent safety architecture (BMS, hardware protection, pressure detection) with wide temperature range thermal management, the device achieves inherent safety and wide environmental adaptability throughout the process. Its highly integrated design condenses the complex protection system into a single device, greatly simplifies the operation process, improves protection efficiency, and realizes a leap from the protection chain to a single-soldier-carrying mode.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] This invention provides, for example Figs. 1-3The device shown is a drone startup and ground power supply unit, including a high-power energy storage module 101, an intelligent battery management system 102, a safety protection and control unit 103, a human-machine interface 104, and a high-reliability power interface 105. The high-power energy storage module 101 is composed of multiple lithium-ion cells arranged in parallel and then in series, with a total nominal voltage of 28V and a nominal capacity of not less than 242Ah. The module is designed to support continuous discharge at a rate of 5C or higher and can provide a continuous peak startup current of not less than 1200A for a duration of ≥5 minutes. The intelligent battery management system 102 is electrically connected to the high-power energy storage module 101 and is used for monitoring, balancing, and thermal management of the cells. The safety protection and control unit 103 is electrically connected to the intelligent battery management system 102 and the high-power energy storage module 101. The safety protection and control unit 103 integrates hardware-driven multiple protection circuits for overcharge, over-discharge, overcurrent, short circuit, over-temperature, and abnormal pressure. Key protection thresholds include: undervoltage protection at 19.6V, overcharge protection at 29.4V, and overtemperature protection at 70℃. All protections are directly driven by hardware with a response time in the microsecond range. The human-machine interface 104 is used to display real-time power, voltage, current, temperature, alarm information, and system status. The high-reliability power interface 105 connects to the output of the high-power energy storage module 101 and is used to connect to the drone. By integrating the high-power energy storage module 101, the intelligent battery management system 102, the safety protection and control unit 103, the human-machine interface 104, and the high-reliability power interface 105, a highly self-sufficient integrated energy security system is constructed. This allows the drone to break free from dependence on a fixed power grid by directly releasing energy from a high-rate battery pack (≥242Ah, 5C continuous discharge, peak 1200A), providing instantaneous, reliable, and electromagnetically interference-free starting power for drones in scenarios without mains power, such as field operations and emergency situations. At the same time, through the combination of multiple hardware protections with microsecond-level response and BMS intelligent monitoring, intrinsic safety from the battery cell to the system is achieved in a wide temperature range. This condenses the traditionally complex protection chain into a single device that can be quickly deployed and operated intuitively, fundamentally improving the maneuverability, survivability, and deployment efficiency of the drone system.

[0022] The intelligent battery management system 102 includes a main control unit 1021, a data acquisition unit 1022, an active balancing unit 1023, a thermal management unit 1024, and a pressure detection unit 1025. The main control unit 1021 is responsible for logic judgment and system coordination; the data acquisition unit 1022 is used to monitor the voltage, total current, and temperature of each battery cell in real time; the active balancing unit 1023 is used to transfer energy to battery cells with excessive voltage deviation during charging or resting; and the thermal management unit 1024 is used to control the heating film integrated inside the battery pack to preheat the battery cells in low-temperature environments. The pressure detection unit 1025 monitors the internal pressure of the battery pack and triggers protection when the pressure rises abnormally. The acquisition unit 1022 performs millisecond-level full-domain monitoring and active balancing of cell voltage, current, and temperature, ensuring the consistency, safety, and long lifespan of the battery pack during high-rate discharge. The thermal management unit 1024, which integrates a heating film, actively extends the low-temperature operating boundary of the equipment, ensuring rapid deployment capability in frigid environments. The independent pressure detection unit 1025, as a final physical defense line, can provide the earliest and most direct warning of potential thermal runaway risks of the battery. Combined with the decision-making logic of the main control unit 1021, it achieves the highest priority emergency protection, enabling the entire power system to achieve an intelligent leap from passively responding to faults to actively predicting and managing risks. This provides a solid intelligent foundation for high-power, high-reliability power supply for UAVs in the field.

[0023] The high-reliability power interface 105 uses a high-current aviation connector with low contact resistance and anti-misplugging features, while the human-machine interface 104 uses an industrial-grade touchscreen. Together, these components ensure ultimate reliability and user-friendliness of the device in harsh field environments. The aviation connector, through its physical characteristics, minimizes energy loss and heat generation when subjected to instantaneous currents of thousands of amperes. Its anti-misplugging design eliminates electrical accidents caused by operational errors at the source. The industrial-grade touchscreen, with its high brightness, wide temperature range, and dust and water resistance, ensures that operators can clearly, accurately, and quickly read critical battery status, execute start-up commands, and receive safety alarms even in strong light, rain, snow, or extreme temperatures. This simplifies complex professional support tasks into intuitive and reliable touch operations, thereby significantly reducing reliance on the external environment and the operator's skill level while improving support efficiency.

[0024] The method of using this invention includes the following specific steps: S1: Self-test and backup power. Perform an appearance and power-on self-test on the device to confirm that there are no faults and that the power is sufficient to meet the task requirements. S2: Reliable connection. When both the device and the drone are powered off, use a dedicated cable to reliably connect and lock their interfaces. S3: Ground power-on check, activate device output, power the UAV onboard system, monitor parameters, and assist in completing the ground function check before takeoff; S4: Critical Start. The device issues an engine start command, intelligently releases a massive instantaneous current to drive the starter motor, and the operator monitors the voltage curve to ensure a smooth and reliable start-up process. S5: Continuous protection and monitoring. After the engine starts successfully, the device switches to continuous power supply mode to support system operation until the drone is ready, and then safely disconnects the output. S6: Retraction and restoration, safely disconnect the connection, retract the cable, shut down the device, charge and maintain as needed, and restore the equipment to operational readiness.

[0025] Steps S1 to S6, through mandatory self-checks, backup power, and reliable connection pre-processing, eliminate the risks of equipment malfunction and poor electrical connections from the source, laying the foundation for safe operation. The subsequent two core stages—ground power-on checks and critical startup—fully leverage the synergistic advantages of intelligent power supply and real-time operator monitoring. This not only ensures uninterrupted power supply to the UAV's onboard equipment but also visually verifies the dynamic superiority of the high-rate battery pack at startup by monitoring voltage curves. The settings for continuous support and orderly withdrawal reflect the design philosophy of full-mission-cycle support and rapid equipment recovery to combat readiness. This process improves the reliability of individual missions while ensuring high availability of equipment in continuous deployments, thereby transforming the technological advantages of advanced equipment into stable and repeatable combat support capabilities. Step S4 includes the following steps: S41: After completing the ground system check, prepare to start the engine; S42: Sends an engine start command to the UAV flight controller or ground control station; S43: At the moment the start command is triggered, the intelligent battery management system 102 and the safety protection and control unit 103 inside the device work together to control the main contactor to close; S44: The high-power energy storage module 101 instantly releases a large current to drive the engine's starter motor through a cable; S45: The operator listens to the engine start-up sound and monitors the voltage curve of the start-up process through the device interface; S46: Once the engine successfully reaches idle speed, the start-up process ends, and the device load current will drop to the level required to maintain power supply.

[0026] Step S4 meticulously decomposes the high-risk, high-dynamic process of engine starting into a closed-loop control sequence from command issuance to state confirmation. Through the collaborative decision-making of the intelligent battery management system 102 and the safety protection unit in S43, the final state verification, including voltage, temperature, and pressure, is completed before closing the main circuit, intercepting potential battery risks at the moment of discharge and achieving intelligent release. Subsequently, in S44, the high-power energy storage module 101 directly releases ultra-large current based on its physical characteristics, ensuring sufficient starting power and no electromagnetic interference with a near-zero delay response and pure DC output. S45 requires the operator to simultaneously perform dual verification by listening to sound and observing the voltage curve, which intuitively links the stability of the internal electrical parameters of the system with the external mechanical response, providing dual criteria for successful starting. Finally, S46 clearly defines the engine reaching idle speed as the technical endpoint of the starting process, making the entire process clear in its objectives and predictable in its results. This transforms the complex action of instantaneous high-power discharge into a safe, reliable, monitorable, and repeatable standard procedure, greatly improving the success rate of starting and operational certainty.

[0027] Step S43 includes the following steps: Final status verification: After receiving the start command trigger signal, the intelligent battery management system 102 performs a final verification of the real-time status of the high-power energy storage module 101. Upon confirmation of the protection unit's readiness, the safety protection and control unit 103 simultaneously confirms that all its hardware protection circuits are in a ready state and that no protection latch has been triggered. When the conditions are met, the intelligent battery management system 102 sends a closing signal to the safety protection and control unit 103 only when all state verifications are passed and the protection unit is confirmed to be ready. Upon receiving a signal indicating permission to close, the safety protection and control unit 103 drives the main contactor to close, thus connecting the discharge circuit.

[0028] Step S43 establishes a final intelligent safety gate before releasing the kiloampere-level current. It transforms the abstract concept of safety into a series of executable and verifiable actions. First, it performs a millisecond-level final assessment of the battery's health (voltage, temperature, pressure), while simultaneously confirming that the hardware protection circuit is in a state of alert. Then, it sets these two conditions as logical requirements that must be met simultaneously; only under these stringent conditions does the system authorize the closure of the main circuit. This process completely changes the traditional simple mode of power supply energizing upon receiving a command. By adding a decision-making checkpoint jointly guarded by the digital management system and the hardware protection circuit, it intelligently intercepts and eliminates the risk of serious accidents caused by poor battery condition or protection circuit failure before discharge occurs. This provides unprecedented deterministic safety assurance for the entire high-power startup process, achieving a fundamental leap from passively accepting risk to actively managing risk.

[0029] The verification parameters include: whether the voltage of each cell is within the preset start-up voltage window, whether the battery core temperature is within the preset start-up temperature range, and whether the pressure detection unit 1025 reports normal pressure.

[0030] Conditional closure includes: The main control unit 1021 of the intelligent battery management system 102 independently evaluates the verification results of each type of parameter in the final state verification and generates the corresponding evaluation state flag. The main control unit 1021 first checks the internal pressure safety assessment flag. If the flag indicates an abnormal pressure, it immediately triggers the highest priority fault latch and generates the final decision of prohibiting closure and pressure fault, skipping all subsequent assessments and logic, and directly enters the fault handling procedure. Under the premise that the pressure safety assessment flag is normal, the main control unit 1021 takes the cell voltage consistency assessment flag, the module temperature adaptability assessment flag, and the protection unit readiness confirmation signal from the safety protection and control unit 103 as three parallel input conditions that must be met simultaneously. When all parallel input conditions continuously indicate normal and ready states within the preset decision time window, the main control unit 1021 generates the final instruction to allow closure and sends the instruction to the safety protection and control unit 103.

[0031] Conditional closure employs an intelligent decision-making algorithm with priority judgment, parallel condition convergence, and strict timing requirements. This algorithm assigns differentiated response levels to different risks, placing the most dangerous and urgent fault signal—pressure anomaly—with the highest priority and granting it veto power, achieving millisecond-level interruption and isolation. This demonstrates the ultimate protection against the greatest risk of lithium battery thermal runaway. After ensuring physical safety, voltage consistency, temperature adaptability, and the readiness status of external protection circuits are set as three parallel conditions that must be met simultaneously. These conditions are synchronously judged within a preset, extremely short time window. This not only ensures the overall compliance of the system state but also enforces real-time decision-making by introducing the concept of a time window, preventing misjudgments or delayed responses due to occasional fluctuations in a condition or system delays. The entire decision-making process strictly follows risk levels, first conducting progressive screening and then synchronously confirming key conditions, thus making the decision-making process for initiating this high-risk action highly structured, predictable, and absolutely reliable.
