The positive electrode and the negative electrode of the unconnected battery are connected to the power supply board 11. It should be noted that in this embodiment, the reason for using nickel sheets as the connection material between the batteries is that nickel sheets not only have good electrical conductivity and corrosion resistance, but also can provide a stable current transmission path, reduce contact resistance, and ensure efficient energy transmission between the batteries.

[0030] Please continue to refer to Figures 1 to 3 , in one embodiment, such as this embodiment, both the first battery assembly 12 and the second battery assembly 13 further include adapter boards.

Specifically, the adapter board in the first battery assembly 12 is called the first adapter board 122, and the adapter board in the second battery assembly 13 is called the second adapter board 132. The adapter board is provided with a positive electrode pad and a negative electrode pad, that is, both the first adapter board 122 and the second adapter board 132 are provided with the positive electrode pad and the negative electrode pad.

[0032] Please refer to Figure 1 and Figure 4 , in an embodiment, such as this embodiment, a voltage feedback pin is reserved on the male connector, and the voltage feedback pin is connected to the bus of the battery pack. Specifically, the voltage feedback pin is reserved on both the first connector 111 and the second connector 112.

Specifically, even if the power management chip 113 is connected to the first battery pack 121 and the second battery pack 131. It should be noted that, in this embodiment, the reason for connecting the voltage feedback pin to the bus of the battery pack is to ensure that the power management chip 113 can directly and accurately read the actual voltage of the battery pack, and this direct connection reduces the interference and loss in the signal transmission process and improves the accuracy of voltage reading. Not only that, but also the real-time voltage monitoring of multiple battery packs is realized, ensuring the rationality and safety of the charging and discharging process of the battery pack. It should also be noted that, in this embodiment, the first connector 111 and the second connector 112 are further provided with a power supply 30 pin and a ground wire pin.

[0033] In an embodiment, such as this embodiment, the surface of the male connector is provided with a nickel-plated structural layer. Specifically, the surfaces of the first connector 111 and the second connector 112 are both provided with the nickel-plated structural layer. It should be noted that in this embodiment, the reason for providing the nickel-plated structural layer on the surfaces of the first connector 111 and the second connector 112 is that it can further reduce the contact resistance. The nickel-plated structural layer not only improves the electrical conductivity of the first connector 111 and the second connector 112, but also enhances their corrosion resistance and wear resistance, thereby extending the service life of the first connector 111 and the second connector 112.

It should also be noted that in this embodiment, the number of layers and the copper thickness of the power supply board 11 are the key factors affecting the impedance of the charge and discharge circuit paths. Increasing the copper thickness can improve the current-carrying capacity and reduce the resistance; while increasing the number of layers can optimize the circuit layout and reduce the length of the current path, thereby reducing the impedance. In practical applications, when designing the power supply board 11, it is necessary to comprehensively consider according to the actual current demand and space limitation to achieve the best current transmission efficiency.

[0035] Please refer to Figure 5 , Figure 5 is a schematic diagram of the drone 100 provided by an embodiment of the present invention. As Figure 5 shown, the drone 100 includes a motor 20, a power supply 30, and the battery system 10 of the drone described above. Among them, the battery system is connected to the motor 20 and the power supply 30 to enable the battery system to supply power to the motor 20 and charge the first battery and the second battery in the battery system through the power supply 30.

[0036] It should be noted that in this embodiment, using a power simulation software, such as power DC, the performance of the battery system under different conditions can be simulated and analyzed. Through simulation, the circuit design can be optimized, the layout of the power supply board can be adjusted, and appropriate materials and dimensions can be selected to achieve the purpose of reducing the impedance of the charge and discharge circuit paths. Simulation can also predict potential performance problems, such as overheating, voltage drop, etc., so as to make necessary adjustments before actual manufacturing.

[0037] In summary, the battery system of the drone in the present utility model can significantly reduce the impedance of the charge and discharge path, improve the efficiency and reliability of the battery system, contribute to enhancing the performance of the drone, extending the battery life, reducing the maintenance cost, and ensuring the stable operation of the drone under various operating conditions; by optimizing the battery layout, the drone not only achieves an optimized balance of the center of gravity, enhancing the flight stability and controllability, but also enhances the heat dissipation effect through the reasonable spacing between battery packs, effectively extending the service life of the battery and the overall safety of the system. In addition, the flexibility of this layout allows adjusting the battery capacity according to the mission requirements, adapting to different endurance requirements by increasing or decreasing the number of battery cells, so that the drone can execute various flight missions more efficiently and flexibly, that is, enhancing the application flexibility and mission adaptability of the drone.

[0038] For the battery system of the drone provided by the present utility model, by respectively arranging the first battery pack and the second battery pack on both sides of the power supply board, and connecting the first battery pack to the power supply board through the first connector and the first adapter board, and connecting the second battery pack to the power supply board through the second connector and the second adapter board, rather than arranging the first battery pack and the second resistor group on the power supply board, not only the space utilization rate of the drone battery system is improved, but also the heat dissipation effect is enhanced. Moreover, the optimized balance of the center of gravity is achieved, enhancing the flight stability and controllability.
