In practical applications, the general drone battery itself will have a built-in discharge circuit, which can be used for discharge. Alternatively, a discharge circuit can be set on the charging position, and the drone battery can also be discharged using the discharge circuit set on the charging position. In this way, after the drone battery is electrically connected to the corresponding charging position, the drone The built-in discharge circuit of the battery itself will be invalid. In order to safely store the drone battery, the discharge circuit of the charging position will be used for discharge. That is to say, when the UAV battery electrically connected to the charging position meets the discharge condition, the controller will control the discharge circuit provided on the charging position to close, so as to control the UAV battery to discharge. Based on this, the unmanned battery management device provided in this embodiment can also include: a discharge circuit electrically connected to a plurality of charging positions, and the discharge circuit is electrically connected to the controller, and the controller can control the discharge circuit electrically connected to it.

During specific implementation, according to actual needs, the controller will have different control schemes corresponding to the discharge circuits of different types of charging positions among the plurality of charging positions. specifically,

For the first type of charging position in the plurality of charging positions

Referring to Fig. 2, the UAV battery management device provided in this embodiment may also include: a first discharge circuit 210 electrically connected to the first type charging position 20, the first discharge circuit 210 is connected to the control device 10 is electrically connected. Correspondingly, the controller 10 can be specifically configured to: control the first discharge circuit to remain in the disconnected state during the process of the first type of charging bit being electrically connected to the battery of the drone. Here, the purpose of controlling the first discharge circuit to remain disconnected is to disable the first discharge circuit, so as to prevent the first discharge circuit from discharging the unmanned aerial vehicle battery electrically connected to the first type of charging position.

The above-mentioned control of the first discharge circuit remains in the disconnected state. Although the first discharge circuit can be prevented from discharging the drone battery electrically connected to the first type of charging potential, since the drone battery itself may still have chemical self-discharge, for this reason The battery of the drone connected to the first type charging bit still has the problem of power loss. In order to keep the power of the UAV battery electrically connected to the first type charging position above the preset power for a long time, it is necessary to detect the power of the UAV battery electrically connected to the first type charging position, so that when the first type of charging is detected When the power of the UAV battery electrically connected to the first type of charging position is lower than the preset power, the first type of charging position is controlled to charge the UAV battery electrically connected to it, so as to charge to more than the preset power. Accordingly, continuing to refer to FIG. 2, the UAV battery management device provided in this embodiment may also include: a power detection unit 220 electrically connected to the first type charging position 20 and a first charging circuit 230; wherein,

The power detection unit 220 is used to detect the power of the drone battery electrically connected to the first type of charging position; the power detection unit 220 is electrically connected to the controller 10; correspondingly,

The controller 10 is specifically configured to: control the first charging circuit when the power detection unit detects that the power of the drone battery electrically connected to the first type charging position is lower than the preset power The first type of charging is to charge the electrically connected UAV battery to above the preset electric quantity.

During specific implementation, the electric quantity detection unit can be used to carry out real-time detection to the unmanned aerial vehicle battery connected to the first type of charging potential, or it can also be detected at intervals of a preset time period; the preset time period can be two days or five days Etc., not limited here. When it is detected that the electric quantity of the unmanned aerial vehicle battery electrically connected to the first type of charging position is lower than the preset electric quantity, the first type of charging position can be controlled to adopt a constant current charging method to charge the unmanned aerial vehicle battery electrically connected to it (hereinafter referred to as the first type drone battery) to charge above the preset power level. And after the first type of charging position is charged to the first type of drone battery to the preset power level, if there is no operation on the first type of drone battery for a period of time, such as no use of the first type of drone battery within 24 hours. When the human battery is discharged or used, the first type of drone battery enters the standby mode. The standby mode means that the power of the first type of drone battery is always above the preset power. For example, if the preset power is set to 90%, the first type of charging position adopts a constant current method for the first type of drone. After the battery is charged to 95%, if no operation is performed on the first-type charging position within 24 hours, the power of the first-type drone battery will always be above 90%, that is to say, the first type has no The human-machine battery will always be kept in a high SOC state, so that the first type of rechargeable battery is always available, so that when there is an emergency mission, the first type of drone battery can be used to power the drone immediately. It meets the basic needs of UAV emergency. And when there is an urgent task, for the UAV battery electrically connected to the second type charging position, the second type charging position can be controlled to quickly charge the corresponding UAV battery. For details on how to control the second type of charging position to charge the corresponding drone battery, please refer to the following related content.

For the second type of charging position in the plurality of charging positions

Referring to Fig. 3, the UAV battery management device provided in this embodiment may also include: a second discharge circuit 310 electrically connected to the second type charging potential; the second discharge circuit 310 is connected to the controller 10 electrical connections; correspondingly,

The controller 10 is specifically configured to: when the drone battery connected to the second type charging potential meets the discharge condition, control the second discharge circuit to close, so as to charge the second type charging potential The connected drone battery is discharged in storage state.

The discharge conditions mentioned above may refer to preset conditions related to the storage duration. For example, when it is detected that the storage duration of the UAV battery electrically connected to the second type of charging potential exceeds the preset duration threshold, it is determined that it is related to the second The battery of the drone connected to the charging potential of the second type satisfies the discharge condition; and the storage time of the battery of the drone connected to the charging potential of the second type mentioned above can be detected by the relevant detection unit (such as the battery presence detection unit). The detected data is obtained. Based on this, in a specific achievable technical solution, the UAV battery management device provided in this embodiment may also include: a battery presence detection unit 320 electrically connected to the second type charging position; The bit detection unit 320 is electrically connected to the controller 10 . Correspondingly,

The controller 10 is also specifically configured to: combine the detection data of the battery presence detection unit to determine whether the storage time of the drone battery electrically connected to the second type of charging position in the second type of charging position is Exceeding the preset duration threshold; when the storage duration exceeds the preset duration threshold, it is determined that the drone battery electrically connected to the second type of charging position satisfies the discharge condition.

In specific implementation, the above-mentioned storage duration refers to the duration of no operation on the drone battery electrically connected to the second type of charging position, and the operation may include but not limited to: plugging, charging, discharging and other operations. The above-mentioned preset duration threshold can be flexibly determined according to the actual situation. For example, the preset duration can be 7 days, one month, etc., which is not limited here. When the storage duration exceeds the preset duration threshold, the controller can control the second discharge circuit to be closed, so as to discharge the UAV battery electrically connected to the second type of charging position in the storage state, so that the second type of charging is a battery The connected drone battery discharges a certain amount of power. For example, taking the preset duration threshold as 7 days as an example, the initial power of the drone battery connected to the second type charging potential (hereinafter referred to as the second type drone battery) is full. When the storage time of the drone battery reaches 7 days, the controller can control the second discharge circuit to close, so that the second type of drone battery discharges 10% of the power, and the remaining power of the second type of drone battery is 90%. ; In the follow-up, if the storage time reaches the preset time threshold again, the second type of drone battery can be discharged by using the second discharge circuit again to release 10% of the power again, and so on. It should be noted that: when the above-mentioned storage duration reaches the preset duration threshold value each time, the electric power released each time can be the same or different, which is not limited here.

In the drone battery management device provided in this embodiment, there are multiple second-type charging positions, and the multiple second-type charging positions are electrically connected to external drone batteries, and the multiple second-type charging positions are electrically connected to external drone batteries. The second type of charging position can use the second charging circuit arranged on it to charge the battery of the drone electrically connected to it respectively. When a plurality of second-type charging positions are respectively charged to the battery of the drone to which it is electrically connected, it is considered that when the temperature of the battery of the drone is too high or too low, charging the battery of the drone may be harmful to the drone. The drone battery will cause damage, which will affect the charging efficiency, service life and safety of the drone battery. For this reason, in order to avoid damage to the UAV battery, it is possible to give priority to charging the UAV battery whose temperature is within the allowable range of the UAV battery. The temperature of the UAV battery can be detected by a temperature sensor. That is, further, the UAV battery management device provided in this embodiment may also include: a plurality of second charging circuits 330 electrically connected to the plurality of second-type charging positions respectively, and a plurality of second charging circuits 330 respectively located in the plurality of second charging positions A plurality of temperature sensors 340 of type charging positions; the plurality of second charging circuits 330 are respectively connected to the controller 10; the plurality of temperature sensors 340 are respectively connected to the controller 10; the temperature sensors 340 are used It is used to detect the temperature of the drone battery electrically connected to the corresponding charging point. Correspondingly,

The controller 10 is further configured to: after receiving the charging instruction, determine that each of the plurality of second-type charging positions is electrically connected to each other according to the temperature of the drone battery that is electrically connected to each of the plurality of second-type charging positions. The charging sequence of the unmanned aerial vehicle battery; according to the charging sequence, control the plurality of second charging circuits to charge the plurality of second-type batteries that are electrically connected to the unmanned aerial vehicle battery.

Here, in order to give priority to meeting the emergency basic needs of the UAV, the controller will preferentially control the first charging circuit electrically connected to the first type of charging position to charge the corresponding UAV battery to the predetermined level after receiving the charging instruction. Set the power above. That is, the above-mentioned controller 10 can be specifically used for:

After receiving the charging instruction, control the first charging circuit electrically connected to the first type charging position to charge the UAV battery electrically connected to the first type charging position to a preset amount;

After the charging of the drone batteries electrically connected to the first type of charging is completed, according to the charging sequence, control the plurality of second charging circuits to charge a plurality of the second types of drone batteries electrically connected to charge.

During specific implementation, for controlling the first charging circuit electrically connected to the first type charging potential to charge the UAV battery electrically connected to the second type charging potential above the preset power level, please refer to the above or the following related content, here No specific details are given. In addition, when the above-mentioned controller 10 determines the charging sequence of the drone batteries electrically connected to each of the plurality of second-type charging positions according to the acquired temperatures of the drone batteries electrically connected to each of the multiple second-type charging positions , the charging sequence of drone batteries whose temperature is within the safe charging temperature range is earlier than that of drone batteries whose temperature is outside the safe charging temperature range. The safe charging temperature range is determined according to the performance of the UAV battery. For example, the safe charging temperature range can be: -20°C ~ 45°C, which is not limited here.

For example, referring to Fig. 1, Fig. 1 shows that the second type of charging position includes: charging position 42, charging position 43 and charging position 44, and charging position 42, charging position 43 and charging position 44 are respectively provided with According to the corresponding temperature sensor, the controller determines the temperature corresponding to the charging position 42 and the charging position 43 respectively according to the temperature of the corresponding drone battery detected by the temperature sensor on the received charging position 42, charging position 43 and charging position 44. The temperature of the drone battery electrically connected is within the safe charging range, and the temperature of the drone battery electrically connected to the charging position 44 is outside the safe charging range. After the controller receives the charging instruction, it can preferentially control the charging position 42 and the charging position 43 to charge the UAV battery electrically connected to it respectively, and then control the charging position 44 to charge the UAV battery electrically connected to it . When specifically controlling the charging position 42 and the charging position 43 to charge the UAV batteries electrically connected to them respectively, the unmanned vehicles electrically connected to the charging position 42 and the charging position 43 can be determined according to the voltage of the UAV battery. The battery charging sequence of the drone battery; among them, the higher the voltage of the drone battery, the higher the corresponding charging priority. The reason for this is: the higher the voltage of the drone battery, the more the remaining power of the drone battery, and the faster it can reach the power required by the drone to perform tasks when charging it. , which can effectively speed up the charging efficiency and shorten the charging time.

Based on this, that is, further, the UAV battery management device provided in this embodiment may also include: a plurality of voltage detection units 350 respectively located at a plurality of the second type charging positions; the voltage detection unit 350 is used to detect The voltage of the battery of the drone electrically connected to the corresponding charging level; the multiple voltage detection units 350 are respectively electrically connected to the controller 10 . Correspondingly,

The controller 10 is specifically used for:

According to the temperature of the drone batteries electrically connected to each of the plurality of charging positions of the second type, at least one first drone battery whose temperature is within the safe charging range and at least one first drone battery whose temperature is outside the safe charging range are determined. at least one second drone battery;

determining the charging sequence of the at least one first drone battery based on the voltage of the at least one first drone battery;

determining a charging sequence for the at least one second drone battery based on the voltage of the at least one second drone battery;

Wherein, in the charging sequence, the charging sequence of the at least one first drone battery is earlier than the charging sequence of the at least one second drone battery.

Continue to refer to FIG. 1 and continue the above example, set the temperature of the drone battery connected to the charging position 42 and the charging position 43 in FIG. 1 to be within a safe temperature range, and the temperature of the drone battery electrically connected to the charging position 44 Located outside the safe temperature range, that is, the charging sequence of the drone batteries electrically connected to the charging station 42 and the charging station 43 is earlier than that of the drone battery electrically connected to the charging station 44 . In this case, if the controller determines the voltage of the charging position 42 according to the received voltage data of the drone battery that is electrically connected to the corresponding charging position detected by the voltage sensors located on the charging position 42 and the charging position 43 respectively. If the voltage of the connected drone battery is higher than the voltage of the drone battery electrically connected to charging position 43, the charging sequence of the drone battery electrically connected to charging position 42 is earlier than that of the drone battery electrically connected to charging position 43. charging sequence. To sum up, the charging order of the UAV battery electrically connected to the charging position 42, the charging position 43 and the charging position 44 determined by the controller is: the drone battery electrically connected to the charging position 42 -> the charging position 43 The unmanned aerial vehicle battery that is electrically connected—>the unmanned aerial vehicle battery that charging position 44 is electrically connected; When the second charging circuit is charging the corresponding unmanned aerial vehicle battery, the second charging circuit that will first control the charging position 42 is charged for the unmanned aerial vehicle battery that is electrically connected with the charging position 42, and then the second charging circuit that controls the charging position 43 is The drone battery electrically connected with the charging position 43 is charged, and finally the second charging circuit controlling the charging position 44 charges the drone battery electrically connected with the charging position 44.

Further, the above-mentioned controller 10 controls the plurality of second charging circuits to electrically connect the plurality of second-type charging positions respectively according to the determined charging sequence of the drone batteries electrically connected to the plurality of second-type charging positions. In the process of charging the UAV battery, specifically, based on the charging modes corresponding to the multiple second-type charging positions, the multiple second charging circuits can be controlled respectively according to the charging modes corresponding to the multiple second-type charging positions. The human-machine battery is charged. The above charging modes can be flexibly set according to different mission scenarios of UAV applications. For example, when the UAV is used in scenes without urgent tasks (such as aerial photography, surveying and mapping), generally there is not much requirement for the charging time of the UAV battery. For this reason, the charging mode corresponding to multiple second-type charging positions can be set as Slow charging mode; when UAVs are used in scenarios with urgent tasks (such as forest disaster relief and police use), it is often required to complete the charging of the UAV battery in a short period of time. For this reason, multiple charging positions can be set corresponding to The charging mode is fast charging mode to shorten the charging time of the drone battery. For the detailed introduction of the slow charging mode and the fast charging mode, please refer to the following relevant content, and details will not be repeated here.

According to the charging sequence and the charging mode, the plurality of second charging circuits are controlled to charge the UAV batteries electrically connected to their corresponding second-type charging positions.

Generally, the battery charging process is divided into two stages: constant current charging stage and constant voltage charging stage. The charging sequence of each battery is: first constant current charging, then constant voltage charging. Among them, the constant voltage charging stage takes the longest time. Generally, at the end of the constant current charging phase, the power of the battery is above 90%, at this time the battery can be put into use to meet emergency needs.

During specific implementation, the above-mentioned slow charging mode refers to charging the UAV batteries electrically connected with multiple charging positions in sequence according to the charging sequence of the drone batteries connected with multiple charging positions at first constant current and then constant voltage charging; The mode refers to the charging sequence of drone batteries connected to multiple charging positions. First, the drone batteries connected to multiple charging positions are charged with a constant current, and the drones connected to multiple charging positions are charged in sequence. After the constant current charging of the battery is completed, return to the constant voltage charging of the drone batteries connected to multiple charging positions in sequence.

For example: continuing the above-mentioned example related to FIG. 1 , FIG. 1 shows the charging sequence of a plurality of second-type charging positions (ie charging positions 42, 43 and 44) electrically connected drone batteries. It is: the drone battery electrically connected to charging position 42—>the drone battery electrically connected to charging position 43—>the drone battery electrically connected to charging position 44. Let the preset power determined according to the power required by the drone to perform the task be 90%, if the charging mode corresponding to the charging position 42, the charging position 43 and the charging position 44 is the slow charging mode, then the controller receives the charging command After that, the second charging circuit on the charging position 42 will first be controlled to charge the UAV battery electrically connected to the charging position 42 with a constant current to 90%, and then to 100% at a constant voltage; After the charging of the human-machine battery is completed, the controller 10 then controls the second charging circuit on the charging position 43 to charge the drone battery electrically connected to the charging position 43 with a constant current to 90%, and then to a constant voltage to 100%; And so on, until the charging of the unmanned aerial vehicle battery connected electrically to the charging position 44 is completed. And if the charging position mode corresponding to the charging position 42, the charging position 43 and the charging position 44 is the fast charging mode, then after the controller receives the charging command, it will firstly control the second charging circuit of the charging position 42 to charge the charging position 42. The connected UAV battery is charged to 90% by constant current, the second charging circuit of charging position 43 is the constant current charge of the drone battery connected by charging position 43 to 90%, and the second charging circuit of charging position 44 is charging The drone battery connected to bit 44 is charged to 90% with a constant current; afterward, the second charging circuit that controls the charging bit 42 is charged to 100% at a constant voltage for the drone battery that is electrically connected to charging bit 42. The second charging circuit of 43 charges the unmanned aerial vehicle battery that the charging position 43 is electrically connected to a constant voltage charge to 100%, and the second charging circuit of the charging position 44 charges the drone battery that the charging position 44 is electrically connected to a constant voltage to 100% .

What needs to be explained here is: based on the above content, in order to give priority to ensuring that the UAV can meet the emergency needs, after receiving the charging command, the controller gives priority to controlling the first charging circuit electrically connected to the first type of charging position For charging the drone battery that is electrically connected to the corresponding first type bit. For this reason, in the above example, when the charging mode is the slow charging mode, after the controller 10 receives the charging command, it will preferentially control the first charging circuit of the first type of charging position (that is, the charging position 41) to charge the corresponding charge The UAV battery connected by bit 41 is first charged to 90% by constant current, and then charged to 100% by constant voltage. After the charging of the unmanned aerial vehicle battery electrically connected to the charging position 41 is completed, the charging sequence of the unmanned aerial vehicle battery electrically connected to a plurality of second-type charging positions (ie charging position 42, charging position 43 and charging position 44) is followed. And in the slow power mode, control the second charging circuit electrically connected to the charging position 42, the charging position 43 and the charging position 44 to charge the drone battery electrically connected to the corresponding charging position. In the case that the charging mode is the fast mode, after receiving the charging instruction, the controller 10 will preferentially control the first charging circuit electrically connected to the first type of charging position (that is, the charging position 41) to the corresponding charging position 41. The drone battery is charged to 90% with a constant current, and then the second charging circuit electrically connected to a plurality of second-type charging positions (that is, the charging position 42, the charging position 43 and the charging position 44) is respectively controlled in turn to charge the corresponding charging position. The connected drone battery is charged to 90% by constant current; after the first type charging position and multiple second type charging positions are connected to the drone battery, the constant current charge is completed to 90%, and then return to control the charging first Bit 41 is electrically connected to the first discharge circuit to charge the UAV battery electrically connected to charging bit 41 at a constant voltage to 100%, and then controls the charging bit 42, charging bit 43, and charging bit 44 respectively in turn. The drone battery connected to the corresponding charging position is charged to 100% at a constant voltage. For details not exhaustive in this example, reference may be made to the relevant content above, and no specific description will be given here.

It can be seen from the above that adopting the fast charging mode can ensure that more batteries that meet the urgent needs can be used as soon as possible.

It should also be noted here that: the above-mentioned first type charging positions can also have multiple, when there are multiple first type charging positions, the charging sequence of the drone batteries electrically connected to the multiple first type charging positions respectively For the determination method, please refer to the method for determining the charging sequence of the drone batteries electrically connected to multiple second-type charging positions, and details will not be repeated here.

Further, in some embodiments, the drone battery management device provided in this embodiment may be provided with first buttons corresponding to multiple charging positions (not shown in the drawings). The charging modes corresponding to the above-mentioned plurality of second-type charging positions can be controlled through the corresponding first buttons. Specifically, according to the application scenario of the drone, the user can switch the charging mode corresponding to the corresponding second type of charging position by long pressing the first button; correspondingly, the controller can The charging mode corresponding to the corresponding second type of charging bit is determined according to the pressing operation data. From this it can be seen that

That is, the controller 10 is also specifically configured to: determine the charging mode corresponding to the plurality of charging positions of the second type according to the pressing operation data of the first button corresponding to the charging positions of the second type.

During specific implementation, after the user presses and holds the first button for a set duration, the charging mode corresponding to the corresponding second type of charging position is switched once. That is to say, the controller can determine the charging mode corresponding to the corresponding second-type charging position according to the long-pressing operation data performed by the user on the first button. For example, assuming that the set duration is 3s, the default charging mode of each second-type charging position is slow charging mode. When the user presses and holds the first button for 3 seconds, the charging mode of the corresponding second-type charging position switches to fast charging. Afterwards, if the user presses and holds the first button again for 3 seconds, the charging mode of the corresponding second charging position will switch to the slow charging mode.

In actual application, three charging modes can be set for each charging position: slow charging mode, fast charging mode and standby mode. Wherein, when the charging mode of a certain charging position is the slow charging mode or the fast charging mode, the charging position is also the second type of charging position; when the charging mode of a certain charging position is the standby mode, the charging position is also the It is the first type charging position. That is to say, the user can simultaneously determine the type of the charging position and the charging mode through the first button corresponding to each charging position. For example: suppose the set duration is 3s, the default charging mode of each charging position is slow charging mode, when the user presses and holds the first button for 3s, the charging mode of the corresponding charging position switches to the fast charging mode; after that, If the user presses and holds the first button again for 3 seconds, the charging mode of the corresponding charging position will switch to the standby mode; after that, if the user presses and holds the first button for 3 seconds again, the charging mode of the corresponding charging position will switch to the slow mode. charging mode.

What needs to be explained here is that after the user finishes switching the charging modes corresponding to the multiple second-type charging positions, the controller 10 can also control the multiple indicator lights corresponding to the multiple charging positions to indicate the current charging mode corresponding to the corresponding charging positions. Different charging modes can be characterized by different light colors; for example, if the light color displayed by the indicator light is yellow, it can indicate that the charging mode corresponding to the corresponding charging position is the standby mode; if the light color displayed by the indicator light is Green indicates that the charging mode corresponding to the corresponding charging level is the fast charging mode; the light color displayed by the indicator light is red, which indicates that the charging mode corresponding to the corresponding charging level is the slow charging mode. Moreover, since the charging mode is related to the type, the light color displayed by the indicator light can also represent the type of the corresponding charging position. Of course, other light colors may also be used to represent different charging modes, which is not limited in this embodiment.

Still further, in addition to the function of switching the charging mode corresponding to the corresponding charging position, the above-mentioned first button can also have the function of checking the battery power of the drone. That is, in some embodiments, the first button can also be used to check the battery level of the drone. Button multiplexing can simplify the structure of the UAV battery charging management device and reduce costs.

During specific implementation, the user can check the battery power of the drone by short-pressing the first button. Specifically, the UAV battery management device provided in this embodiment may further include a display, which may be connected to the controller 10, and the display may be used to display the power of the UAV battery electrically connected to the charging position. For example, when the user performs a short press operation on the first button, the controller can control the display to display the electric quantity of the drone battery connected to the corresponding charging position after the controller receives the short press operation data about the first button. also,

In the technical solution provided by this embodiment, the UAV battery management device includes a controller, a first type charging position and a second type charging position; the first type charging position and the second type charging position are respectively electrically connected to an external The drone battery; the controller can be used to control the drone battery connected to the first type of charging potential to keep above the preset power level; wherein, the preset power level is required for the drone to perform a specified task The electric quantity is determined; when the drone battery electrically connected to the second type charging position meets the preset discharge condition, discharge processing in the storage state is carried out. On the one hand, the solution uses the first type of charging position to keep at least the UAV battery electrically connected to the first type of charging position in a high SOC state for a long time, which can ensure that the UAV meets the basic needs of emergencies and is conducive to improving user experience; on the other hand The second-type charging position can enable the drone battery electrically connected to the second-type charging position to perform discharge processing in the storage state under the preset conditions, which is beneficial to reduce the loss of the drone battery.

To sum up, the technical solution provided by this embodiment has the following beneficial effects: 1. It can meet the basic emergency needs of the UAV and help reduce the battery loss of the UAV.

In addition, the UAV batteries that are electrically connected with multiple second-type charging potentials will perform discharge processing in the storage state when they meet the discharge conditions. When there is an urgent task, this solution can also be implemented as multiple second-type batteries. The charging bit is electrically connected to the drone battery for fast charging. It can be seen that this solution not only meets the basic needs of UAV emergency, but also makes most UAV batteries stored in a suitable SOC state, which is beneficial to reduce UAV battery loss and improve user experience. 2. For different scenarios of drone applications, two charging modes, fast charging and slow charging, are provided, which can meet the different charging needs of users and help improve user experience. For example, when the drone is used in a scene with urgent tasks, the user can choose the fast charging mode to charge the battery of the drone to ensure that the battery can be used as soon as possible; when the drone is used in a scene without urgent tasks, Users can choose the slow charging mode to charge the drone's battery.
