However, due to the increasing traffic congestion in cities, especially in large cities, people waste more and more time in traffic jams. In order to make travel more convenient and faster, people have thought of developing flying cars, which can drive on the road like cars and fly in the air, avoiding traffic jams on the road and reaching the destination quickly and conveniently.

[0084] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0085] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0086] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0087] With the advancement of science and technology and the development of society, people's living standards have been greatly improved, and their requirements for travel have become higher and higher. However, due to the increasing traffic congestion in cities, especially in large cities, people waste more and more time in traffic jams. In order to make travel more convenient and faster, people have thought of developing flying cars, which can drive on the road like cars and fly in the air, avoiding traffic jams on the road and reaching the destination quickly and conveniently.

[0088] At present, flying cars are mainly integrated flying cars. Whether flying in the air or driving on the ground, the air module and the ground module of the integrated flying car are always integrated, and the overall load burden is relatively large, and the flexibility is poor. Therefore, split flying cars came into being. In the split flying car, the power supply part is divided into the land body battery pack and the flying body battery pack to supply power to the land body load and the flying body load respectively. Therefore, the split flying car has a new demand for charging solutions.

[0089] In order to provide a new charging solution for a split flying car, the present invention proposes a charging control method, which is applied to a two-split flying car. The two-split flying car includes a land body battery pack, a flying body battery pack, a voltage regulating module and a charging port. The charging port is respectively connected to the input end of the land body battery pack and the voltage regulating module, and the output end of the voltage regulating module is connected to the flying body battery pack. Figure 1 and Figure 2 In one embodiment, the charging control method includes:

[0090] Step S100, receiving a charging instruction, and determining a charging mode according to the charging instruction;

[0091] Step S200, determining a charging object according to a charging mode, and after controlling the charging object to be powered on, selecting and controlling a voltage regulating module and a charging device connected to a charging port to output a corresponding amount of power to the corresponding charging object for charging.

[0092] In this embodiment, the two-part flying car includes a land battery pack, a flying battery pack, a voltage regulating module and a charging port, wherein the charging port is connected to the input end of the land battery pack and the voltage regulating module respectively, and the output end of the voltage regulating module is connected to the flying battery pack. Corresponding main positive contactors and main negative contactors can be provided inside the land battery pack and the flying battery pack to control the power on and off of the land battery pack and the flying battery pack. Figure 1 , Figure 1 This is a circuit structure diagram of an embodiment of a two-split flying car. As shown in the figure, the charging port, the voltage regulating module and the land body battery pack are arranged on the land body part of the car, and the flying body battery pack is arranged on the flying body part of the car. The charging port includes a DC charging port and an AC charging port. The land body battery pack and the flying body battery pack both include a main positive contactor, a main negative contactor and a pre-charge contactor. When the main positive contactor and the main negative contactor in the battery pack are closed, the battery pack is controlled to be powered on.

[0093] It is understandable that in the two-part flying car, a control module for receiving charging instructions can be provided, and the control module can be composed of a processor, such as an MCU, a DSP (Digital Signal Process), an FPGA (Field Programmable Gate Array), etc., for receiving charging instructions issued by the user. It is understandable that the control module for receiving charging instructions can be the original central controller in the two-part flying car, or it can be an additional control module dedicated to charging control.

[0094] In a two-body flying car, the user can issue a charging instruction through a control panel or other input components. When receiving the charging instruction issued by the user, the charging mode can be determined according to the charging instruction. The charging mode includes at least a land body charging mode, a flying body charging mode, and a land-fly co-charging mode, that is, the charging device charges the land body battery pack, the charging device charges the flying body battery pack, and the charging device charges the land body battery pack and the flying body battery pack together. It can be understood that in addition to the above three charging modes, the land body battery pack can charge the flying body battery pack, and the flying body battery pack can charge the land body battery pack.

[0095] After determining the charging object according to the charging mode, the corresponding charging object is controlled to be powered on. For example, in the land-based charging mode, the charging object is a land-based battery pack, and the main positive contactor and the main negative contactor in the land-based battery pack are controlled to be closed, that is, the land-based battery pack is controlled to be powered on. After the charging object is controlled to be powered on, the voltage regulating module and / or the charging device connected to the charging port are selected to output a corresponding amount of power to the powered-on charging object, so that the charging device connected to the charging port can charge the charging object. Specifically, when charging the land-based battery pack, the charging device connected to the charging port is controlled to directly charge the land-based battery pack. When charging the flying body battery pack, the charging device connected to the charging port is controlled to charge the flying body battery pack through the voltage regulating module. When charging the land-based battery pack and the flying body battery pack at the same time, the charging device connected to the charging port is controlled to directly charge the land-based battery pack, and to charge the flying body battery pack through the voltage regulating module.

[0096] In the technical solution of the present invention, when a charging instruction issued by the user is received, the charging mode is determined according to the charging instruction, and then the charging object is determined according to the charging mode. After the charging object is powered on, the voltage regulation module and the charging device connected to the charging port are selected to output power of corresponding size to the corresponding charging object for charging, so as to realize the charging of the designated charging object, thereby meeting the charging needs of the two-split configuration flying car.

[0097] Reference Figure 3 In one embodiment, the steps of determining the charging object according to the charging mode, and controlling the charging object to be powered on, and then selecting and controlling the voltage regulating module and the charging port to output a corresponding amount of power to the corresponding charging object for charging include:

[0098] Step S300: when it is determined according to the charging mode that the charging object is a land-based battery pack, controlling the land-based battery pack to be powered on, and controlling the charging device connected to the charging port to charge the land-based battery pack;

[0099] In one embodiment, when it is determined that the charging object is a land-based battery pack according to the charging mode, that is, in the land-based charging mode, when the charging object is a land-based battery pack, the main positive contactor and the main negative contactor in the land-based battery pack are controlled to close, that is, the land-based battery pack is controlled to be powered on, and then the charging device connected to the charging port is controlled to directly charge the land-based battery pack to realize the charging of the land-based battery pack. It can be understood that the charging requirements of the land-based battery pack, such as charging current and charging power, can be obtained, so as to control the corresponding output of the charging device connected to the charging port according to the required charging requirements to meet the charging requirements of the land-based battery pack.

[0100] Step S400: When it is determined according to the charging mode that the object to be charged is a flying body battery pack, the flying body battery pack is controlled to be powered on, and the voltage regulating module is controlled to regulate the output voltage of the charging device connected to the charging port, and then the flying body battery pack is charged.

[0101] In another embodiment, when it is determined that the charging object is a flying body battery pack according to the charging mode, that is, in the flying body charging mode, when the charging object is a flying body battery pack, the main positive contactor and the main negative contactor in the flying body battery pack are controlled to be closed, that is, the flying body battery pack is controlled to be powered on, and the voltage regulating module is controlled to work in the forward direction, so that the voltage regulating module charges the flying body battery pack after regulating the output voltage of the charging device connected to the charging port, so as to realize the charging of the flying body battery pack. It can be understood that the charging requirements of the flying body battery pack, such as the charging current and the charging power, can be obtained, so as to control the corresponding output of the charging device connected to the charging port according to the charging requirements to meet the charging requirements of the flying body battery pack.

[0102] Reference Figure 4 In one embodiment, the steps of controlling the land-based battery pack to be powered on and controlling the charging device connected to the charging port to charge the land-based battery pack include:

[0103] Step S310, controlling the land vehicle battery pack to be powered on, and controlling the voltage regulating module to stop working;

[0104] Step S320, obtaining the charging current of the land vehicle battery pack;

[0105] Step S330: Control the charging device connected to the charging port to output the charging current of the land-based battery pack to charge the land-based battery pack.

[0106] In this embodiment, when it is determined that the charging object is a land-based battery pack according to the charging mode, that is, in the land-based charging mode, when the charging object is a land-based battery pack, the main positive contactor and the main negative contactor in the land-based battery pack are controlled to close, that is, the land-based battery pack is controlled to be powered on, and the voltage regulation module is controlled to enter the standby mode, that is, the voltage regulation module is controlled to stop working, thereby isolating the flying body battery pack by controlling the voltage regulation module to prevent current from charging into the flying body battery pack. After the voltage regulation module is controlled to stop working, the charging current of the land-based battery pack is obtained, and according to the obtained charging current, the charging device connected to the charging port is controlled to output the charging current of the land-based battery pack to realize the charging of the land-based battery pack. It can be understood that the charging current of the land-based battery pack can be pre-set and stored in the memory, or it can be obtained by communicating with the land-based battery pack, or it can be obtained by calculation.

[0107] Reference Figure 5 Optionally, the step of obtaining the charging current of the land vehicle battery pack includes:

[0108] Step S321, obtaining the charging demand current of the land vehicle battery pack, the carrying current of the charging cable and the maximum output current of the charging device;

[0109] Step S322: compare the acquired charging demand current of the land-based battery pack, the carrying current of the charging cable, and the maximum output current of the charging device in sequence, and use the smallest current as the charging current of the land-based battery pack.

[0110] It is understandable that when different charging devices are connected, the maximum output current that the charging device can provide is also different. At the same time, different charging cables can carry different currents. Therefore, in this embodiment, the charging demand current of the land-based battery pack, the carrying current of the charging cable, and the maximum output current of the charging device are first obtained, and then they are compared in turn to obtain the minimum current, and the minimum current is used as the charging current of the land-based battery pack to charge the land-based battery pack. For example, when the maximum output current of the charging device is the minimum current, it is obvious that the output current of the charging device cannot reach the charging demand current of the land-based battery pack. Therefore, the charging device can only be controlled to output at the maximum output current to charge the land-based battery pack.

[0111] Reference Figure 6 In one embodiment, after controlling the flying body battery pack to power on and controlling the voltage regulating module to regulate the output voltage of the charging device connected to the charging port, the step of charging the flying body battery pack includes:

[0112] Step S410, controlling the battery pack of the flying object to be powered on;

[0113] Step S420, obtaining the charging current of the battery pack of the flying body;

[0114] Step S430, controlling the voltage regulating module to output the charging current of the flying body battery pack;

[0115] Step S440, deriving an input current of a voltage regulating module according to the charging current of the battery pack of the flying body;

[0116] Step S450: Control the output of the charging device connected to the charging port according to the input current of the voltage regulation module to charge the battery pack of the flying body.

[0117] In this embodiment, when it is determined that the charging object is a flying body battery pack according to the charging mode, that is, in the flying body charging mode, when the charging object is a flying body battery pack, the main positive contactor and the main negative contactor in the flying body battery pack are controlled to be closed, that is, the flying body battery pack is controlled to be powered on. Then the charging current of the flying body battery pack is obtained, and the voltage regulating module is controlled to output positively with the charging current of the flying body battery pack. At the same time, the input current of the voltage regulating module is calculated according to the charging current of the flying body battery pack, so that according to the input current of the voltage regulating module, the charging device connected to the charging port is controlled to output with the calculated input current of the voltage regulating module, so as to meet the charging demand of the flying body battery pack and charge the flying body battery pack. It can be understood that the charging current of the flying body battery pack can be pre-set and stored in the memory, or it can be obtained by communication with the flying body battery pack, or it can be obtained by calculation.

[0118] Reference Figure 7 Optionally, the step of obtaining the charging current of the battery pack of the flying body includes:

[0119] Step S421, obtaining the charging demand current of the battery pack of the flying object, the carrying current of the charging cable, and the maximum output current of the charging device;

[0120] Step S422: compare the acquired charging demand current of the flying body battery pack, the carrying current of the charging cable, and the maximum output current of the charging device in sequence, and use the smallest current as the charging current of the flying body battery pack.

[0121] It is understandable that when the connected charging devices are different, the maximum output current that the charging devices can provide is also different. At the same time, different charging cables can carry different currents. Therefore, in this embodiment, the charging demand current of the flying body battery pack, the carrying current of the charging cable and the maximum output current of the charging device are first obtained, and then they are compared in turn to obtain the smallest current, and the smallest current is used as the charging current of the flying body battery pack to charge the flying body battery pack. It is understandable that when the maximum output current of the charging device is the minimum current, it is obvious that the output current of the charging device cannot reach the charging demand current of the flying body battery pack. Therefore, the charging device can only be controlled to output at the maximum output current, and the flying body battery pack is charged through the voltage regulation module.

[0122] Reference Figure 8 Optionally, the step of deriving the input current of the voltage regulation module according to the charging current of the flying body battery pack includes:

[0123] Step S441, obtaining the input voltage, output voltage and working efficiency of the voltage regulation module;

[0124] Step S442: multiply the charging current of the flying body battery pack by the output voltage of the voltage regulating module, and divide the result by the working efficiency of the voltage regulating module to obtain the output power of the charging device;

[0125] Step S443: Divide the output power of the charging device by the input voltage of the voltage regulating module to obtain the input current of the voltage regulating module.

[0126] In this embodiment, when the charging current of the flying body battery pack is determined, the input current of the voltage regulation module can be calculated according to the charging current of the flying body battery pack. Specifically, the input voltage, output voltage and working efficiency of the voltage regulation module are first obtained, and then the charging current of the flying body battery pack is multiplied by the output voltage of the voltage regulation module, and then divided by the working efficiency of the voltage regulation module, that is, the output power of the charging device is calculated according to (charging current*output voltage) / working efficiency of the voltage regulation module, and then the calculated output power of the charging device is divided by the input voltage of the voltage regulation module to calculate the input current of the voltage regulation module.

[0127] Reference Fig. 9 Optionally, the step of controlling the output of the charging device connected to the charging port according to the input current of the voltage regulating module to charge the battery pack of the flying body includes:

[0128] Step S451, obtaining the actual charging current of the battery pack of the flying body in real time;

[0129] Step S452: When the actual charging current of the flying body battery pack is less than the charging current of the flying body battery pack, control the charging device connected to the charging port to gradually increase the output current until the actual charging current of the flying body battery pack is equal to the charging current of the flying body battery pack.

[0130] It is understandable that when the flying body battery pack is actually charged, errors may occur due to calculation or conductor impedance, etc. Therefore, in the present embodiment, the actual charging current of the flying body battery pack can also be obtained in real time, and the obtained actual charging current of the flying body battery pack can be compared with the charging current of the flying body battery pack. When the actual charging current of the flying body battery pack is less than the charging current of the flying body battery pack, the charging device is controlled to gradually increase the output current, so that the actual charging current of the flying body battery pack gradually increases until the actual charging current of the flying body battery pack is equal to the charging current of the flying body battery pack and the adjustment is stopped. Similarly, when the actual charging current of the flying body battery pack is greater than the charging current of the flying body battery pack, the charging device can be controlled to gradually reduce the output current until the actual charging current of the flying body battery pack is equal to the charging current of the flying body battery pack and the adjustment is stopped.

[0131] Reference Fig.10Optionally, before the step of controlling the flying body battery pack to be powered on, the method further includes:

[0132] Step S411, detecting the high voltage state of the land vehicle battery pack;

[0133] Step S412, when the land-based battery pack is in a high-voltage state, controlling the voltage regulating module to stop working, and then controlling the land-based battery pack to power down at high voltage;

[0134] Step S413: When the land-based battery pack is not in a high-voltage state, executing a step of controlling the flying-based battery pack to be powered on.

[0135] It is understandable that when charging the flying body battery pack, if the land-based battery pack is still in the power-on state, when the charging device charges the flying body battery pack, a part of the current will be divided to charge the land-based battery pack. Therefore, in this embodiment, before controlling the flying body battery pack to be powered on, the high-voltage state of the land-based battery pack is first detected, that is, whether the main positive contactor and the main negative contactor of the land-based battery pack are turned off. If it is detected that the land-based battery pack is in the high-voltage state, the voltage regulation module is first controlled to stop working, and then the high-voltage power of the land-based battery pack is controlled to be turned off, that is, the main positive contactor and the main negative contactor of the land-based battery pack are controlled to be turned off. If it is detected that the land-based battery pack is not in the high-voltage state, the flying body battery pack can be controlled to be powered on to charge the flying body battery pack. In this way, it can be avoided that when charging the flying body battery pack, the charging speed of the flying body battery pack is limited or even damaged due to the high-voltage state of the land-based battery pack, thereby improving the safety and efficiency of charging.

[0136] Reference Fig.11 In one embodiment, the step of determining the charging object according to the charging mode, and after controlling the charging object to be powered on, selecting and controlling the voltage regulating module and the charging port to output a power supply of a corresponding size to the corresponding charging object for charging also includes:

[0137] Step S500: When it is determined according to the charging mode that the objects to be charged include both a flying body battery pack and a land body battery pack, control the land body battery pack and the flying body battery pack to be powered on, control the voltage regulation module to regulate the output voltage of the charging device connected to the charging port, and then charge the flying body battery pack, and control the charging device connected to the charging port to charge the land body battery pack.

[0138] In this embodiment, when it is determined that the charging object is the flying body battery pack and the land body battery pack according to the charging mode, that is, in the land-flight co-charging mode, when the charging object is the flying body battery pack and the land body battery pack, the main positive contactor and the main negative contactor in the land body battery pack and the flying body battery pack are controlled to be closed, that is, the land body battery pack and the flying body battery pack are controlled to be powered on, and the voltage regulation module is controlled to work in the forward direction, so that the voltage regulation module charges the flying body battery pack after regulating the output voltage of the charging device connected to the charging port, and at the same time, the charging device connected to the charging port charges the land body battery pack, so as to realize the charging of the land body battery pack and the flying body battery pack at the same time. It can be understood that the charging requirements of the flying body battery pack and the land body battery pack can be obtained, such as the charging current and the charging power, and then the charging requirements of the flying body battery pack and the land body battery pack are added to obtain the power that the charging device should output, so as to control the corresponding output of the charging device connected to the charging port according to the charging requirements to meet the charging requirements of the flying body battery pack and the land body battery pack.

[0139] Reference Fig.12 Optionally, the steps of controlling the power-on of the land-based battery pack and the flying-based battery pack, controlling the voltage regulating module to regulate the output voltage of the charging device connected to the charging port and then charging the flying-based battery pack, and controlling the charging device connected to the charging port to charge the land-based battery pack include:

[0140] Step S510, controlling the land-based battery pack and the flying-based battery pack to be powered on;

[0141] Step S520, obtaining the total charging current;

[0142] Step S530: Control the charging device connected to the charging port and the output of the voltage regulating module according to the total charging current to charge the land-based battery pack and the flying battery pack.

[0143] In this embodiment, when it is determined that the charging object is a land-based battery pack and a flying battery pack according to the charging mode, that is, in the land-fly co-charging mode, when the charging object is a land-based battery pack and a flying battery pack, the main positive contactor and the main negative contactor in the land-based battery pack and the flying battery pack are controlled to be closed, that is, the land-based battery pack and the flying battery pack are controlled to be powered on. Then the total charging current is obtained, that is, the total charging current required for charging the land-based battery pack and the flying battery pack at the same time, and the output of the charging device and the voltage regulating module connected to the charging port is controlled according to the total charging current, so that the charging device connected to the charging port charges the land-based battery pack while charging the flying battery pack through the voltage regulating module to meet the charging requirements of the land-based battery pack and the flying battery pack. It can be understood that the total charging current can be pre-set and stored in the memory, or it can be obtained by communicating with the land-based battery pack and the flying battery pack, or it can be obtained by calculation.

[0144] Reference Fig.13 Optionally, the step of obtaining the total charging current includes:

[0145] Step S521, obtaining the charging current of the land vehicle battery pack, the input current of the voltage regulation module, the carrying current of the charging cable, and the maximum output current of the charging device;

[0146] Step S522, comparing the sum of the charging current of the land vehicle battery pack and the input current of the voltage regulation module with the carrying current of the charging cable and the maximum output current of the charging device in sequence;

[0147] Step S523: compare the sum of the charging current of the land-based battery pack and the input current of the voltage regulation module, the carrying current of the charging cable and the maximum output current of the charging device in sequence, and take the smallest one as the total charging current.

[0148] It is understandable that when different charging devices are connected, the maximum output current that the charging device can provide is also different. At the same time, different charging cables can carry different currents. Therefore, in this embodiment, the charging current of the land-based battery pack, the input current of the voltage regulation module, the carrying current of the charging cable and the maximum output current of the charging device are first obtained, and then the charging current of the land-based battery pack is added to the input current of the voltage regulation module to obtain the required total current, and then the required total current is compared with the carrying current of the charging cable and the maximum output current of the charging device in turn, and the smallest current is taken as the total charging current. It is understandable that when the maximum output current of the charging device is the minimum current, it is obvious that the output current of the charging device cannot reach the total charging demand current of the flying body battery pack and the land-based battery pack, so the charging device can only be controlled to output at the maximum output current.

[0149] Reference Fig.14 Optionally, when the sum of the charging current of the land-based battery pack and the input current of the voltage regulation module is not the minimum current, the step of controlling the output of the charging device connected to the charging port according to the total charging current to charge the land-based battery pack and the flying battery pack includes:

[0150] Step S531, obtaining energy management mode;

[0151] Step S532: When the acquired energy management mode is the flight priority mode, the charging current of the flying body battery pack is acquired, the charging device connected to the charging port is controlled to output the total charging current, and the voltage regulation module is controlled to output the charging current of the flying body battery pack.

[0152] Step S533, when the acquired energy management mode is the land-based priority mode, the charging current of the land-based battery pack is acquired, the charging device connected to the charging port is controlled to output the total charging current, and the input current of the voltage regulation module is controlled to output the difference current between the total charging current and the charging demand current of the land-based battery pack.

[0153] It is understandable that when the sum of the charging current of the land-based battery pack and the input current of the voltage regulating module is not the minimum current, that is, when the output current of the charging device cannot reach the total charging demand current of the flying body battery pack and the land-based battery pack, at this time, the charging demand of the land-based battery pack or the flying body battery pack can only be met first according to the needs of the user. Therefore, in this embodiment, when the sum of the charging current of the land-based battery pack and the input current of the voltage regulating module is not the minimum current, the energy management mode is first obtained, that is, it is determined whether the land-based battery pack or the flying body battery pack is charged first.

[0154] Specifically, when the energy management mode is the flight priority mode, that is, when the flying body battery pack is charged first, the charging device connected to the charging port is first controlled to output the total charging current, and then the voltage regulation module is controlled to output the charging current of the flying body battery pack, so that the charging device connected to the charging port preferentially meets the charging demand of the flying body battery pack. At this time, the charging current of the flying body battery pack is the charging current it needs, and the charging current of the land body battery pack is the difference current between the total charging current and the input current of the voltage regulation module. Similarly, when the energy management mode is the land priority mode, that is, when the land body battery pack is charged first, the charging device connected to the charging port is first controlled to output the total charging current, and then the input current of the voltage regulation module is controlled to output the difference current between the total charging current and the charging demand current of the land body battery pack. At this time, the charging current of the land body battery pack is the charging current it needs, and the charging current of the flying body battery pack is the difference current between the total charging current and the charging current of the land body battery pack.

[0155] Reference Fig.15 Optionally, when the energy management mode is the flight priority mode, the step of controlling the output of the charging device connected to the charging port according to the total charging current to charge the land-based battery pack and the flying battery pack further includes:

[0156] Step S534, obtaining the actual charging current of the battery pack of the flying body in real time;

[0157] Step S535: when the actual charging current of the flying body battery pack is less than the charging current of the flying body battery pack, controlling the voltage regulating module to gradually increase the output current until the actual charging current of the flying body battery pack is equal to the charging current of the flying body battery pack;

[0158] Step S536: When the actual charging current of the flying body battery pack is greater than the charging current of the flying body battery pack, the voltage regulation module is controlled to gradually reduce the output current until the actual charging current of the flying body battery pack is equal to the charging current of the flying body battery pack.

[0159] It is understandable that when the flying body battery pack is actually charged, errors may occur due to calculation or conductor impedance, etc. Therefore, in the present embodiment, when the energy management mode is the flight priority mode, the actual charging current of the flying body battery pack is also acquired in real time, and the acquired actual charging current of the flying body battery pack is compared with the charging current of the flying body battery pack. When the actual charging current of the flying body battery pack is less than the charging current of the flying body battery pack, the voltage regulation module is controlled to gradually increase the output current, so that the actual charging current of the flying body battery pack gradually increases until the actual charging current of the flying body battery pack is equal to the charging current of the flying body battery pack and the regulation is stopped. Similarly, when the actual charging current of the flying body battery pack is greater than the charging current of the flying body battery pack, the voltage regulation module can be controlled to gradually reduce the output current until the actual charging current of the flying body battery pack is equal to the charging current of the flying body battery pack and the regulation is stopped.

[0160] Reference Fig.16 Optionally, when the energy management mode is the land priority mode, the step of controlling the output of the charging device connected to the charging port according to the total charging current to charge the land-based battery pack and the flying-based battery pack further includes:

[0161] Step S537, obtaining the actual charging current of the land vehicle battery pack in real time;

[0162] Step S538, when the actual charging current of the land-based battery pack is less than the charging current of the land-based battery pack, controlling the voltage regulation module to gradually reduce the output current until the actual charging current of the land-based battery pack is equal to the charging current of the land-based battery pack;

[0163] Step S539: when the actual charging current of the land-based battery pack is greater than the charging current of the land-based battery pack, control the voltage regulation module to gradually increase the output current until the actual charging current of the land-based battery pack is equal to the charging current of the land-based battery pack.

[0164] It is understandable that when the land-based battery pack is actually charged, errors may occur due to calculation or conductor impedance, etc. Therefore, in this embodiment, when the energy management mode is the land-based priority mode, the actual charging current of the land-based battery pack is also obtained in real time, and the actual charging current of the land-based battery pack obtained is compared with the charging current of the land-based battery pack. When the actual charging current of the land-based battery pack is less than the charging current of the land-based battery pack, the voltage regulation module is controlled to gradually reduce the output current, so that the input current of the voltage regulation module is also reduced, so that the actual charging current of the land-based battery pack is gradually increased, until the actual charging current of the land-based battery pack is equal to the charging current of the land-based battery pack, and the regulation is stopped. Similarly, when the actual charging current of the land-based battery pack is greater than the charging current of the land-based battery pack, the voltage regulation module can be controlled to gradually increase the output current, and the regulation is stopped when the actual charging current of the land-based battery pack is equal to the charging current of the land-based battery pack.

[0165] In the technical solution of the present invention, when the land body and the flying body can be charged at the same time, combined with the energy management mode, the land priority mode gives priority to the charging of the land battery pack, and the flight priority mode gives priority to the charging of the flight battery pack, so as to deeply explore user needs and improve the user experience.

It can be understood that the control module can be one, and one control module realizes the control of the land part and the flying part, and the control module can also be divided into two, one is a land body control module for realizing the control of the land part, and the other is a flying body control module for realizing the control of the flying part.
