[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1

[0030] Reference Figure 1-2 , which is the first embodiment of the present invention, provides a battery management method for an unmanned aerial vehicle carrier platform, which can solve the problems of low efficiency, poor environmental adaptability, insufficient living security for personnel, difficulty in energy replenishment, limited data collection and remote control capabilities, insufficient battery management technology and low equipment integration faced by existing power transportation and power grid construction technologies in complex and remote environments.

[0031] Specifically, the charging power of the battery pack is adjusted by a dynamic power regulation charging management algorithm;

[0032] Determine battery charging requirements and strategies based on flight mission requirements;

[0033] By implementing fast charging technology, charging time can be shortened and the flight efficiency of drones can be improved;

[0034] Avoid over-charging and discharging by setting an appropriate charge and discharge cut-off voltage.

[0035] Furthermore, the dynamic power regulation charging management algorithm monitors key parameters such as battery voltage, current, and temperature in real time through built-in sensors and BMS.

[0036] It should be noted that BMS monitoring is the battery management system, which includes real-time monitoring of battery status, analysis of real-time needs of drones, dynamic adjustment of charging power, safety protection mechanism, optimization of charging strategy, as well as user interface and feedback, as follows:

[0037] Real-time monitoring of battery status: Through built-in sensors and BMS, key parameters such as battery voltage, current, and temperature can be monitored in real time;

[0038] Analyze the real-time needs of the drone: The algorithm calculates the required power output based on the drone’s current mission requirements, such as flight altitude, speed, load, etc.

[0039] Dynamically adjust charging power: Based on the real-time status of the battery and the needs of the drone, the algorithm dynamically adjusts the output power of the charging device. When the battery is low or needs to be replenished quickly, the algorithm increases the charging power. When the battery is close to full or the drone's needs decrease, the algorithm reduces the charging power to avoid overcharging.

[0040] Safety protection mechanism: The algorithm has built-in safety protection mechanisms, such as overcharge, over-discharge, and overheating protection, to ensure that the battery operates within a safe range. If an abnormality is detected, such as excessive temperature or abnormal voltage, the algorithm will automatically reduce the charging power or suspend charging.

[0041] Optimize charging strategy: The algorithm will optimize the charging strategy based on the battery's historical data and usage patterns to extend the battery's service life. For example, the algorithm may use pulse charging technology when the battery is close to full charge to reduce battery aging;

[0042] User Interface and Feedback: The user interface allows operators to view the real-time status of the battery and charging progress.

[0043] Furthermore, the flight mission requirements include flight time, flight distance, and payload, that is, the battery compartment is linked to the discharge power of the battery pack during the aircraft's flight, and the required charging power is dynamically adjusted according to the flight mission requirements to meet the battery charging performance within the UAV's battery replacement cycle.

[0044] Furthermore, fast charging technology accelerates the charging process by providing higher current than standard charging, and monitors and manages the battery status, including voltage, current and temperature, through the BMS.

[0045] It should be noted that the principles of fast charging technology include charging at high currents and using advanced charging algorithms to manage the charging process, ensuring that the charging speed is increased without compromising the health and life of the battery. During fast charging, the battery temperature is controlled to prevent overheating that would damage the battery and reduce its performance.

[0046] The charging strategy needs to be developed based on the current state of the battery and the expected usage pattern. For example, if the battery is low, a high charging rate can be used to quickly charge it; if the battery is close to full, a lower charging rate can be switched to avoid overcharging.

[0047] Implement multiple safety measures such as overcharge protection, overheat protection, and short circuit protection to ensure battery safety during fast charging;

[0048] Provides a user interface that displays charging status, estimated charging completion time, and any necessary maintenance reminders.

[0049] Furthermore, determining the charge and discharge cut-off voltage includes determining the rated voltage of the battery, determining the discharge threshold of the battery, determining the battery type and chemical composition, and determining the discharge depth of the battery.

[0050] It should be noted that the charge cut-off voltage is usually set below the rated voltage of the battery to avoid overcharging. For example, if the rated voltage of the battery is 4.2V (for lithium-ion batteries), the charge cut-off voltage may be set to 4.1V or lower. In a high temperature environment, the charge cut-off voltage may need to be set lower to prevent the battery from overheating. This method uses the BMS to monitor the battery temperature and adjust the charge cut-off voltage according to the temperature.

[0051] The discharge cut-off voltage is the lowest voltage that the battery can be safely discharged to. For lithium-ion batteries, the discharge cut-off voltage is usually set between 2.5V and 3.0V. It should be noted that deep discharge will damage the battery and shorten its life, so the discharge cut-off voltage should be set high enough to avoid the battery voltage dropping to a dangerous level. In addition, the battery discharge depth should also be considered. The discharge depth refers to the proportion of the battery released in a charge and discharge cycle. The deeper the discharge depth of the battery, the higher the discharge cut-off voltage should be set.

[0052] In summary, the present invention effectively improves the transportation efficiency of electric power materials in remote mountainous areas through the vehicle-mounted drone cluster solution, and at the same time provides comprehensive life security and work support for on-site personnel. In addition, this technology also optimizes the energy replenishment process, and significantly improves the battery replenishment efficiency and service life through dynamic power regulation charging management algorithm and fast charging technology. At the same time, through advanced data collection and remote control capabilities, the accuracy and safety of operations are enhanced. Overall, this technology not only improves the efficiency and reliability of electric power transportation, but also greatly improves the working environment of operators, ensuring the safety and comfort of operations.

[0055] Specifically, the transport unit 100 includes a transport platform vehicle body 101, a transport component 102 arranged on the upper side of the transport platform vehicle body 101, a control component 103 arranged on one side of the vehicle cockpit, a battery management component 104 arranged on one side of the control component 103, and a life support component 105 arranged on the upper side of the transport platform vehicle body 101.

[0056] Furthermore, the carrier assembly 102 includes a UAV hangar cover 102a and a UAV fixing support 102b disposed on the upper side of the carrier platform vehicle body 101 .

[0057] It should be noted that the drone fixed support 102b is provided with a fixed buckle, and the drone is fixedly connected to the drone fixed support 102b through the fixed buckle. The drone hangar cover 102a is arranged on the outside of the drone to protect the drone from external environmental influences, such as wind, rain, dust, etc.

[0058] Furthermore, the control component 103 includes a drone control display 103a, a human-machine operation control workstation 103b connected to the drone control display 103a, a drone communication device 103c connected to the human-machine operation control workstation 103b, a drone operation work recorder 103d connected to the human-machine operation control workstation 103b, and a drone environment monitoring switch 103e connected to the human-machine operation control workstation 103b.

[0059] It should be noted that the drone control display 103a displays the drone's flight status, map, and sensor data; the drone communication equipment 103c is responsible for data transmission with the drone, including control instructions and flight data; the operator controls the take-off, flight, and landing of the drone through the drone operation control workstation 103b; the drone operation work recorder 103d records the data of the flight mission for subsequent analysis and review; the drone environment monitoring switch 103e monitors and exchanges environmental data around the drone, such as temperature, humidity, air pressure, etc.

[0060] Furthermore, the battery management component 104 includes a drone battery fixing bracket 104a, a drone battery charging management program 104b connected to the human-machine operation control workstation 103b, and a drone battery management program 104c connected to the human-machine operation control workstation 103b.

[0061] It should be noted that the drone battery charging management program 104b manages the battery charging process, including charging speed, charging status monitoring, etc.; the drone battery fixing bracket 104a fixes the battery to ensure stability during transportation and charging; the drone battery management program 104c monitors the health status of the battery, including voltage, current, temperature, etc., and implements protection measures.

[0062] Furthermore, the life support component 105 includes a life support compartment 105a arranged on the upper side of the carrying platform vehicle body 101, a storage box 105b arranged on the top of the life support compartment 105a, an on-board life support refrigerator 105c arranged on the inner side of the life support compartment 105a, an on-board life heating device 105d arranged on the inner side of the life support compartment 105a, and a life support drinking water device 105e arranged on the inner side of the life support compartment 105a.

[0063] How this system works: Before starting, a thorough system inspection of the entire drone carrier platform, including the drone, battery, control equipment and communication system, is performed, and the operating environment, including terrain, weather conditions and specific requirements of the operating area, is evaluated. Further, the flight path, mission objectives and expected operating time of the drone are planned according to the operational requirements. The BMS is used to monitor the current status of the battery, including power, voltage and temperature, and a charging strategy is implemented based on the battery status and mission requirements. If the battery is low, fast charging technology is used to charge it, and the charging power is dynamically adjusted according to the real-time needs of the drone and the battery status to optimize the charging efficiency and battery life.

[0064] When using a drone, the operator issues a take-off command through the control workstation in the drone flight control cabin, and the drone takes off autonomously or semi-autonomously. During the flight, the drone control display 103a monitors the flight status of the drone in real time, including position, speed and attitude. The drone performs tasks according to the preset flight path, such as material transportation, line inspection or data collection. The drone transmits flight data and mission data back to the ground control station through communication equipment.

[0065] When the mission is completed, the operator or the drone autonomously executes the landing procedure, the drone lands safely, and the operator records the flight data and mission data for analysis and review to evaluate the execution of the mission. If necessary, the drone battery is charged and prepared for the next flight mission.

[0066] In summary, the present invention effectively improves the transportation efficiency of electric power materials in remote mountainous areas through the vehicle-mounted drone cluster solution, and at the same time provides comprehensive life security and work support for on-site personnel. In addition, this technology also optimizes the energy replenishment process, and significantly improves the battery replenishment efficiency and service life through dynamic power regulation charging management algorithm and fast charging technology. At the same time, through advanced data collection and remote control capabilities, the accuracy and safety of operations are enhanced.
