[0096] Specifically, the above step S203 may include the following steps:

[0097] Step S2031, adding the flight battery current demand, the land battery current demand and the land load current demand to calculate the total current demand.

[0098] Specifically, the electronic device adds the flight battery current demand, the ground battery current demand and the ground load current demand to calculate the total current demand.

[0099] Exemplarily, the electronic device adds the flight battery current requirement A4, the land battery current requirement A2, and the land load current requirement A5 to obtain A4+A2+A5.

[0100] Step S2032: If the output is greater than or equal to the total current demand, based on the current of the flight battery current demand requested by the buck-boost module in the flight battery, the current of the flight battery current demand in the output current is input to the flight battery to charge the flight battery; the current of the land battery current demand in the output current is input to the land battery to charge the land battery; and the current of the land load current demand in the output current is input to the land load to meet the current demand of the land load.

[0101] Specifically, the electronic device may compare the output with the total current demand. If the output is greater than or equal to the total current demand, it is determined that the output current output by the charging pile can simultaneously meet the current demand of the land load, the charging demand of the flight battery, and the charging demand of the land battery. Therefore, the electronic device does not need to obtain the priorities corresponding to the land battery, the flight battery, and the land load. The electronic device controls the buck-boost module in the flight battery to request the current of the flight battery current demand, inputs the current of the flight battery current demand in the output current to the flight battery, and charges the flight battery. The electronic device inputs the current of the land battery current demand in the output current to the land battery, and charges the land battery. The electronic device inputs the current of the land load current demand in the output current to the land load, and meets the current demand of the land load.

[0102] Step S2033: if the output is less than the total current demand, the priorities corresponding to the land battery, the flight battery and the land load are obtained respectively.

[0103] Specifically, if the output is less than the total current demand, the electronic device determines that the output current output by the charging pile cannot simultaneously meet the current demand of the land load, the charging demand of the flight battery, and the charging demand of the land battery. Therefore, the electronic device needs to obtain the priorities corresponding to the land battery, the flight battery, and the land load.

[0104] Optionally, the electronic device may obtain the priorities corresponding to the land battery, the flight battery and the land load respectively based on user instructions.

[0105] Optionally, in order to ensure that the flying car can work normally, the electronic device may determine the priority of the land load as the highest priority, and then determine the priority of the flying battery and the land battery according to the remaining power of the flying battery and the land battery respectively. The less the remaining power, the higher the priority.

[0106] Optionally, in order to ensure that the flying car can work normally, the electronic device may determine the priority of the land load as the highest priority, and then obtain the user's travel plan, and determine the priority of the flying battery and the land battery according to the user's travel plan. If the travel plan is to travel on land, the priority of the land battery is higher than the flying battery, and if the travel plan is to fly, the priority of the land battery is lower than the flying battery.

[0107] Step S2034, charging the land load and the flight battery and / or the land battery according to the relationship between the output and the flight battery current demand, the land battery current demand, the land load current demand, and the priorities corresponding to the land battery, the flight battery, and the land load.

[0108] In an optional implementation of the present application, if the priority of the land load is higher than the priority of the land battery, and the priority of the land battery is higher than the priority of the flight battery, the above step S2034 may include the following situations:

[0109] The first case:

[0110] Step a1: If the output is greater than or equal to the sum of the land battery current demand and the land load current demand, and is less than the total current demand, the current required by the land battery in the output current is input into the land battery to charge the land battery, and the current required by the land load is input into the land load to meet the current demand of the land load.

[0111] Specifically, if the output is greater than or equal to the sum of the current demand of the land battery and the current demand of the land load, and is less than the total current demand, then the electronic device determines that the current demand of the land load and the charging demand of the land battery can be met first, based on the fact that the priority of the land load is higher than the priority of the land battery, and the priority of the land battery is higher than the priority of the flight battery. Therefore, the electronic device inputs the current demand of the land battery in the output current to the land battery to charge the land battery, and inputs the current demand of the land load to the land load to meet the current demand of the land load.

[0112] Step a2, calculating a first difference current between the output and the sum of the land battery current requirement and the land load current requirement.

[0113] Specifically, the electronic device calculates a first difference current between the output amount and the sum of the land battery current requirement and the land load current requirement.

[0114] Step a3: Based on the current of the first difference current requested by the buck-boost module, the current of the first difference current in the output current is input into the flight battery to charge the flight battery.

[0115] Specifically, the electronic device can control the buck-boost module to request a current of the first difference current amount, input the current of the first difference current amount in the output current into the flight battery, and charge the flight battery.

[0116] Exemplarily, assuming that the output current of the charging pile is A1, that is, A2+A5≤A1<A2+A4+A5, for the flight side: control the buck-boost module to make a current request according to A1-(A2+A5), that is, give the remaining current to charge the flight battery; for the land side: make a charging current request according to the land load demand current A5 and the land battery demand current A2, meet the land side current demand, and perform charging current control.

[0117] The second case:

[0118] Step b1, if the output is greater than or equal to the land load current requirement and less than the sum of the land battery current requirement and the land load current requirement, then calculate a second difference current between the output and the land load current requirement.

[0119] Specifically, if the output amount is greater than or equal to the land load current requirement and less than the sum of the land battery current requirement and the land load current requirement, the electronic device determines that the output current can meet the current requirement of the land load. Therefore, the electronic device calculates a second difference current amount between the output amount and the land load current requirement.

[0120] Step b2: if the second difference current is less than the sum of the minimum charging current of the land battery and the minimum charging current of the flight battery, then the current required by the land load in the output current is input to the land load to meet the current demand of the land load; and the buck-boost module is controlled not to make a current request to prohibit charging the flight battery; and the current required by the second difference current in the output current is input to the land battery to charge the land battery.

[0121] Specifically, the electronic device may obtain the minimum charging current of the land battery and the minimum charging current of the flight battery.

[0122] Then, the electronic device compares the second difference current with the sum of the minimum charging current of the land battery and the minimum charging current of the flight battery. If the second difference current is less than the sum of the minimum charging current of the land battery and the minimum charging current of the flight battery, it is determined that the remaining current after meeting the current demand of the land load is insufficient to meet the minimum charging current of the land battery and the minimum charging current of the flight battery.

[0123] However, since the priority of the land battery is higher than that of the flight battery, the electronic device inputs the current required by the land load in the output current to the land load to meet the current demand of the land load. Then, the electronic device controls the buck-boost module not to make a current request to prohibit charging the flight battery. The electronic device inputs the current of the second difference current in the output current to the land battery to charge the land battery.

[0124] Step b3: If the second difference current is greater than or equal to the sum of the minimum charging current of the land battery and the minimum charging current of the flight battery, the current required by the land load in the output current is input to the land load to meet the current demand of the land load; and the buck-boost module is controlled to request the current of the minimum charging current of the flight battery, and the current of the minimum charging current of the flight battery in the output current is input to the flight battery to charge the flight battery.

[0125] Specifically, if the second difference current is greater than or equal to the sum of the minimum charging current of the land battery and the minimum charging current of the flight battery, the electronic device determines that the remaining current after satisfying the current demand of the land load satisfies the minimum charging current of the land battery and the minimum charging current of the flight battery. Therefore, the electronic device can input the current of the land load current demand in the output current to the land load to meet the current demand of the land load. In addition, the electronic device controls the buck-boost module to request the current of the minimum charging current of the flight battery, and inputs the current of the minimum charging current of the flight battery in the output current to the flight battery to charge the flight battery.

[0126] Step b4, calculating a third difference current between the second difference current and the minimum charging current of the flight battery.

[0127] Specifically, the electronic device may calculate the third difference current by subtracting the minimum charging current of the flight battery from the second difference current.

[0128] Step b5, inputting the current of the third difference current in the output current into the land battery to charge the land battery.

[0129] Specifically, the electronic device may input a current having a third difference current amount in the output current into the land battery to charge the land battery.

[0130] Exemplarily, assuming that the output current of the charging pile is A1, A5≤A1<A2+A5, that is, the capacity of the charging pile can meet the current demand of the land load, but cannot meet the total demand of the land battery and the land load.

[0131] Under this condition, the flight side control strategy is implemented according to the residual current A1-A5, i.e., the second difference current. ① When the residual current is less than the sum of the minimum charging current A7 of the land battery (the trickle charging current of the land battery) and the minimum charging current A8 of the flight battery (the trickle charging current of the flight battery), the electronic device controls the buck-boost module not to make a current request, and completely limits the charging of the flight battery; ② When the residual current is greater than or equal to the sum of the minimum charging current A7 of the land battery (the trickle charging current of the land battery) and the minimum charging current A8 of the flight battery (the trickle charging current of the flight battery), the electronic device controls the buck-boost module to make a current request according to A8, and inputs the current of A8 among A1-A5 to the flight battery. The currents other than A8 among the residual currents A1-A5 are allocated to the charging of the land battery. Therefore, the current request of the land load is preferentially met, and the residual current is allocated in combination with the flight side control strategy.

[0132] The third case:

[0133] Step c1: if the output is less than the land-based load current demand, the remaining power of the land-based battery is obtained.

[0134] Optionally, if the output is less than the land-based load current demand, the electronic device may obtain the remaining power of the land-based battery based on the communication connection with the battery system.

[0135] Optionally, the electronic device may also monitor parameters such as the voltage, current and temperature of the land-based battery in real time, and then calculate the remaining power of the land-based battery based on the monitored parameters such as the voltage, current and temperature of the land-based battery.

[0136] Step c2: if the remaining power of the land battery is greater than or equal to the first preset power threshold, the output current is input to the land load, and the buck-boost module is controlled not to make a current request, and the flight battery is prohibited from charging or discharging.

[0137] Specifically, the electronic device may receive a first preset power threshold value input by a user, may receive a first preset power threshold value sent by other devices, and may also set the first preset power threshold value according to attribute information of a land-based battery.

[0138] Then, the electronic device compares the remaining power of the land battery with the first preset power threshold. If the remaining power of the land battery is greater than or equal to the first preset power threshold, the electronic device inputs the output current to the land load, and controls the buck-boost module not to make a current request, prohibiting the flight battery from charging or discharging.

[0139] Step c3, calculating a fourth difference current between the land load current demand and the output current.

[0140] Specifically, the electronic device calculates and obtains the fourth difference current by subtracting the output current from the row load current demand.

[0141] Step c4, controlling the land-based battery to output a fourth differential current to the land-based load.

[0142] Specifically, the electronic device controls the land-based battery to output a fourth difference current to the land-based load, thereby meeting the current demand of the land-based load.

[0143] Step c5, if the remaining power of the land battery is less than the first preset power threshold, the output current is input to the land load, and the buck-boost module is controlled to make a reverse current request to control the flight battery to output a fourth difference current to the land load.

[0144] Specifically, if the remaining power of the land battery is less than the first preset power threshold, the electronic device inputs the output current to the land load, and controls the buck-boost module to make a reverse current request to control the flight battery to output a fourth difference current to the land load, thereby meeting the current demand of the land load.

[0145] Exemplarily, if A1<A5, the capacity of the charging pile cannot meet the land load demand, and cannot meet the total demand of the land battery, the land load and the flight battery;

[0146] For the land side, the land battery discharges to meet the current demand of the land load. For the flight side, there are the following control strategies based on the current that the land battery can currently discharge: ① If the land battery discharge meets the current demand of the land load, that is, the remaining power of the land battery is greater than or equal to the first preset power threshold, the buck-boost module is controlled not to make a current request, and the flight battery charging / discharging is completely restricted; ② If the land battery discharge cannot meet the current demand of the land load, that is, the remaining power of the land battery is less than the first preset power threshold, the buck-boost module is controlled to make a reverse current request to discharge the land load to meet the current demand of the land load.

[0147] In another optional implementation of the present application, if the priority of the land load is higher than the priority of the flight battery, and the priority of the flight battery is higher than the priority of the land battery, the above step S2034 may include the following situations:

[0148] The first case:

[0149] Step d1: if the output is greater than or equal to the flight battery current requirement and less than the total current requirement, a fifth difference current between the output and the flight battery current requirement is calculated.

[0150] Specifically, if the output is greater than or equal to the current demand of the flight battery and less than the total current demand, the electronic device determines that the output current output by the charging pile can meet the current demand of the flight battery, but cannot meet the current demand of the land load, the flight battery, and the land battery at the same time. Then, the electronic device can use the output to subtract the current demand of the flight battery to calculate the fifth difference current.

[0151] Step d2: If the fifth difference current is greater than or equal to the current demand of the land load, the buck-boost module is controlled to request current according to the current demand of the flight battery, and the current of the flight battery current demand in the output current is input to the flight battery to charge the flight battery, and the current of the land load current demand in the output current is input to the land load to meet the current demand of the land load.

[0152] Specifically, the electronic device may compare the fifth difference current with the land load current requirement. If the fifth difference current is greater than or equal to the land load current requirement, the electronic device determines that the output current output by the charging pile can meet the flight battery current requirement and the land load current requirement.

[0153] Since the priority of the land load is higher than that of the flight battery, and the priority of the flight battery is higher than that of the land battery, the electronic device can control the buck-boost module to request current according to the current demand of the flight battery, input the current of the flight battery current demand in the output current to the flight battery, and charge the flight battery. In addition, the electronic device inputs the current of the land load current demand in the output current to the land load to meet the current demand of the land load.

[0154] Step d3, calculating a sixth difference current between the fifth difference current and the land load current demand.

[0155] Specifically, the electronic device calculates the sixth difference current by subtracting the land load current demand from the fifth difference current.

[0156] Step d4, inputting the sixth difference current in the output current into the land battery to charge the land battery.

[0157] Specifically, the electronic device inputs a sixth difference current in the output current into the land battery to charge the land battery.

[0158] Step d5: if the fifth difference current is less than the land-running load current requirement, the remaining power of the land-running battery is obtained.

[0159] Specifically, if the fifth difference current is less than the land load current requirement, the electronic device can obtain the remaining power of the land battery.

[0160] Step d6: if the remaining power of the land-based battery is greater than or equal to the second preset power threshold, a current of the fifth difference current in the output current is input to the land-based load.

[0161] Specifically, the electronic device can compare the remaining power of the land-based battery with the second preset power threshold, and if the remaining power of the land-based battery is greater than or equal to the second preset power threshold, the electronic device determines that the land-based battery can charge the land-based load, thereby meeting the current demand of the land-based load. Therefore, the electronic device inputs the current of the fifth difference current in the output current to the land-based load.

[0162] Step d7, calculating a sixth difference current between the land load current demand and the fifth difference current.

[0163] Specifically, the electronic device can calculate the sixth difference current by subtracting the fifth difference current from the land load current demand.

[0164] Step d8, controlling the land-based battery to input a sixth differential current into the land-based load.

[0165] Specifically, the electronic device may control the land-based battery to input a current of the sixth difference current amount to the land-based load, thereby meeting the current demand of the land-based load.

[0166] Step d9: if the remaining power of the land running battery is less than the second preset power threshold, the current required by the land running load in the output current is input to the land running load to meet the current demand of the land running load.

[0167] Specifically, if the remaining power of the land battery is less than the second preset power threshold, the electronic device determines that the land battery cannot charge the land load. Therefore, the electronic device inputs the current required by the land load in the output current to the land load to meet the current demand of the land load.

[0168] Step d10, calculating a seventh difference current between the output current and the land load current demand.

[0169] Specifically, the electronic device calculates the seventh difference current by subtracting the land load current demand from the output.

[0170] Step d11, controlling the buck-boost module to input the seventh difference current in the output current into the flight battery to charge the flight battery.

[0171] Specifically, the electronic device controls the buck-boost module to request a current of the seventh difference current, so that the current of the seventh difference current in the output current is input to the flight battery to charge the flight battery.

[0172] For example, if A4≤A1<A2+A4+A5, the capacity of the charging pile can meet the demand of the flight battery, but cannot meet the overall current demand of the three:

[0173] Under this condition, for the flight side: control the buck-boost module to make a current request according to A4, that is, give priority to charging the flight battery; for the land side: distribute the remaining current A1-A4 to the land side, and the remaining current has the following processing measures:

[0174] 1. If A5≤A1-A4, the remaining current will be given to the land load first to ensure the load demand of the whole vehicle, and the remaining current A1-A4-A5 will be given to the land battery;

[0175] 2. A5>A1-A4, then the control strategy is: ① The remaining current A1-A4 is given to the load, and the insufficient part A5-(A1-A4) is satisfied by the discharge of the land battery;

[0176] ② To avoid the discharge of the land battery, the A1 current is used to meet the load first, and the remaining current A1-A5 is given to the flight battery by controlling the buck-boost module to balance the power consumption of the land load and the current required by the flight battery.

[0177] The second case:

[0178] Step e1, if the output is greater than or equal to the land load current requirement and less than the flight battery current requirement, the remaining power of the land battery is obtained.

[0179] Specifically, if the output is greater than or equal to the land load current demand and less than the flight battery current demand, the electronic device determines that the output can meet the land load current demand but cannot meet the flight battery current demand, so the electronic device obtains the remaining power of the land battery.

[0180] Step e2: if the remaining power of the land battery is greater than or equal to the third preset power threshold, the buck-boost module is controlled to make a current request according to the current demand of the flight battery, and the output current is input to the flight battery.

[0181] Specifically, the electronic device may receive a third preset power threshold value input by a user, or may receive a third preset power threshold value sent by other devices. The embodiment of the present application does not specifically limit the manner in which the electronic device obtains the third preset power threshold value.

[0182] Then, the electronic device compares the remaining power of the land battery with the third preset power threshold. If the remaining power of the land battery is greater than or equal to the third preset power threshold, the electronic device determines that the land battery can supply power to the flight battery. Therefore, the electronic device controls the buck-boost module to make a current request according to the current demand of the flight battery, and inputs the output current to the flight battery.

[0183] Step e3, calculating an eighth difference current between the output current and the flight battery current requirement.

[0184] Specifically, the electronic device may calculate the eighth difference current by subtracting the output current from the flight battery current demand.

[0185] Step e4, controlling the land battery to input a current of the eighth difference current amount to the flight battery.

[0186] Specifically, the electronic device may control the land battery to input a current of the eighth difference current amount into the flight battery, thereby meeting the charging demand of the flight battery.

[0187] Step e5, controlling the land-based battery to input a current corresponding to the land-based load current requirement to the land-based load.

[0188] Specifically, the electronic device controls the land-based battery to input a current of the land-based load current demand amount to the land-based load, thereby meeting the current demand of the land-based load.

[0189] Step e6, if the remaining power of the land battery is less than the third preset power threshold, control the buck-boost module to make a current request according to the output amount, and input the output current to the flight battery; control the land battery to input the battery of the land load current demand amount to the land load; or, input the current of the land load current demand amount in the output current to the land load; control the buck-boost module to make a current request according to the ninth difference current amount between the output amount and the land load current demand amount, and input the current of the ninth difference current amount in the output current to the flight battery.

[0190] Specifically, if the remaining power of the land battery is less than the third preset power threshold, the electronic device determines that the land battery cannot supply power to the flight battery. Therefore, the electronic device controls the buck-boost module to make a current request according to the output amount, and inputs the output current to the flight battery. Then, the electronic device controls the land battery to input the battery of the land load current demand to the land load.

[0191] or,

[0192] The electronic device can input the current of the land load current demand in the output current to the land load, thereby meeting the current demand of the land load. Then, the electronic device controls the buck-boost module to make a current request according to the ninth difference current between the output current and the land load current demand, and inputs the ninth difference current in the output current to the flight battery.

[0193] For example, A5≤A1<A4, that is, the capacity of the charging pile cannot meet the needs of the flight battery:

[0194] Under this condition, the following control strategies are implemented according to the land battery power status (Note: B1: the land battery power threshold that can be used to charge the flight battery):

[0195] 1. If the power of the land battery is ≥ B1, the current demand of the flight battery on the flight side is met, and the buck-boost module is controlled to make a current request according to A4. The charging pile current is supplied to the flight battery for charging. The current difference A4-A1 is provided by the discharge of the land battery, and the land load demand current A5 is also provided by the land battery;

[0196] 2. If the power of the land battery is less than B1, the land battery is not allowed to discharge to charge the flight battery. Strategy 1: Control the buck-boost module to request current according to A1. The current provided by the charging pile is given to the flight battery, and the current consumption A5 of the land load is provided by the land battery. Strategy 2: Control the buck-boost module to request current according to A1-A5. The land load does not discharge. The current A1 provided by the charging pile is distributed to the flight battery and the land load.

[0197] The third case:

[0198] Step f1, if the output is less than the current demand of the land load, control the buck-boost module to make a current request according to the output, and input the output current to the flight battery; control the land battery to input the current of the land load current demand to the land load.

[0199] Specifically, if the output is less than the current demand of the land load, the electronic device determines that the output current of the charging pile cannot meet the current demand of the land load. Therefore, the electronic device can control the buck-boost module to make a current request according to the output, input the output current to the flight battery, and control the land battery to input the current demand of the land load to the land load, thereby meeting the current demand of the land load.

[0200] or,

[0201] Step f2, input the output current to the land load, and calculate the tenth difference current between the land load current demand and the output, control the land battery to input the tenth difference current to the land load, and control the buck-boost module not to make a current request, thereby prohibiting charging of the flight battery.

[0202] Specifically, the electronic device can input the output current to the land load, calculate the tenth difference current between the land load current demand and the output, and control the land battery to input the tenth difference current to the land load, thereby meeting the current demand of the land load.

[0203] The buck-boost module is controlled not to make current requests, and charging of the flight battery is prohibited.

[0204] The flying car charging method provided in the embodiment of the present application adds the current demand of the flight battery, the current demand of the land battery and the current demand of the land load to calculate the total current demand, thereby ensuring the accuracy of the total current demand obtained. If the output is greater than or equal to the total current demand, based on the current of the flight battery current demand requested by the buck-boost module in the flight battery, the current of the flight battery current demand in the output current is input to the flight battery to charge the flight battery; and the current of the land battery current demand in the output current is input to the land battery to charge the land battery; and the current of the land load current demand in the output current is input to the land load to meet the current demand of the land load. Thus, when the output is greater than or equal to the total current demand, the current demand of the land load is met and the flight battery and the land battery can be charged at the same time.

[0205] If the output is less than the total current demand, the priorities corresponding to the land battery, the flight battery and the land load are obtained respectively; according to the relationship between the output and the flight battery current demand, the land battery current demand, the land load current demand and the priorities corresponding to the land battery, the flight battery and the land load respectively, the land load and the flight battery and / or the land battery are charged, so that the output current of the charging pile can be better distributed to adapt to different charging scenarios and user needs.

[0206] In one case, the priority of the land load is higher than the priority of the land battery, and the priority of the land battery is higher than the priority of the flight battery. If the output is greater than or equal to the sum of the current demand of the land battery and the current demand of the land load, and is less than the total current demand, the current of the land battery current demand in the output current is input to the land battery to charge the land battery, thereby meeting the charging demand of the land battery. And the current of the land load current demand is input to the land load to meet the current demand of the land load. A first difference current between the output and the sum of the land battery current demand and the land load current demand is calculated; based on the current of the first difference current requested by the buck-boost module, the current of the first difference current in the output current is input to the flight battery to charge the flight battery, thereby meeting the current demand of the land load and the charging demand of the land battery, and then charging the flight battery.

[0207] If the output is greater than or equal to the current demand of the land load, and less than the sum of the current demand of the land battery and the current demand of the land load, the second difference current between the output and the current demand of the land load is calculated, so as to ensure the accuracy of the calculated second difference current. If the second difference current is less than the sum of the minimum charging current of the land battery and the minimum charging current of the flight battery, the current of the land load current demand in the output current is input to the land load, so as to meet the current demand of the land load; and the buck-boost module is controlled not to make a current request, so as to prohibit charging the flight battery; the current of the second difference current in the output current is input to the land battery, so as to charge the land battery. It is realized that the land battery is charged while meeting the current demand of the land load. If the second difference current is greater than or equal to the sum of the minimum charging current of the land battery and the minimum charging current of the flight battery, the current of the land load current demand in the output current is input to the land load, so as to meet the current demand of the land load. The step-up / down voltage module is controlled to request the minimum charging current of the flight battery, and the current of the minimum charging current of the flight battery in the output current is input to the flight battery to charge the flight battery; a third difference current between the second difference current and the minimum charging current of the flight battery is calculated; and the current of the third difference current in the output current is input to the land battery to charge the land battery. Thus, it is ensured that more current can be input to the land battery to charge the land battery while meeting the current demand of the land load.

[0208] If the output is less than the current demand of the land load, the remaining power of the land battery is obtained; if the remaining power of the land battery is greater than or equal to the first preset power threshold, the output current is input to the land load, and the buck-boost module is controlled not to make a current request, and the flight battery is prohibited from charging or discharging; a fourth difference current between the current demand of the land load and the output is calculated; the land battery is controlled to output the fourth difference current to the land load, so as to meet the current demand of the land load. If the remaining power of the land battery is less than the first preset power threshold, the output current is input to the land load, and the buck-boost module is controlled to make a reverse current request to control the flight battery to output the fourth difference current to the land load, so as to meet the current demand of the land load.

[0209] In another optional embodiment, the priority of the land load is higher than that of the flight battery, and the priority of the flight battery is higher than that of the land battery. If the output is greater than or equal to the current demand of the flight battery and less than the total current demand, the fifth difference current between the output and the current demand of the flight battery is calculated to ensure the accuracy of the calculated fifth difference current. If the fifth difference current is greater than or equal to the current demand of the land load, the buck-boost module is controlled to request the current according to the current demand of the flight battery, and the current of the flight battery current demand in the output current is input to the flight battery to charge the flight battery, thereby meeting the charging demand of the flight battery. And the current of the land load current demand in the output current is input to the land load, thereby meeting the current demand of the land load. The sixth difference current between the fifth difference current and the current demand of the land load is calculated; the current of the sixth difference current in the output current is input to the land battery to charge the land battery. Thus, the charging demand of the flight battery and the current demand of the land load are met while charging the land battery.

[0210] If the fifth difference current is less than the current demand of the land load, the remaining power of the land battery is obtained; if the remaining power of the land battery is greater than or equal to the second preset power threshold, the current of the fifth difference current in the output current is input to the land load. Then, the sixth difference current between the current demand of the land load and the fifth difference current is calculated; the land battery is controlled to input the sixth difference current to the land load, so as to meet the current demand of the land load. If the remaining power of the land battery is less than the second preset power threshold, the current of the land load current demand in the output current is input to the land load, so as to meet the current demand of the land load. The seventh difference current between the output and the current demand of the land load is calculated; the seventh difference current in the output current is input to the flight battery by controlling the buck-boost module to charge the flight battery. Thus, the flight battery is charged while meeting the current demand of the land load.

[0211] If the output is greater than or equal to the current demand of the land load and less than the current demand of the flight battery, the remaining power of the land battery is obtained; if the remaining power of the land battery is greater than or equal to the third preset power threshold, the buck-boost module is controlled to make a current request according to the current demand of the flight battery, and the output current is input to the flight battery, so that the flight battery can be charged. The eighth difference current between the output and the current demand of the flight battery is calculated; the land battery is controlled to input the eighth difference current to the flight battery; the land battery is controlled to input the current of the land load current demand to the land load. In this way, the current demand of the land load can be met, and the flight battery can be charged.

[0212] If the remaining power of the land battery is less than the third preset power threshold, the buck-boost module is controlled to make a current request according to the output amount, and the output current is input to the flight battery; the land battery is controlled to input the battery of the land load current demand amount to the land load; or, the current of the land load current demand amount in the output current is input to the land load; the buck-boost module is controlled to make a current request according to the ninth difference current amount between the output amount and the land load current demand amount, and the current of the ninth difference current amount in the output current is input to the flight battery. In this way, the flight battery is charged while the land load current demand is met.

[0213] If the output is less than the current demand of the land load, the buck-boost module is controlled to make a current request according to the output, and the output current is input to the flight battery; the land battery is controlled to input the current of the land load current demand to the land load; or, the output current is input to the land load, and the tenth difference current between the land load current demand and the output is calculated, the land battery is controlled to input the tenth difference current to the land load, and the buck-boost module is controlled not to make a current request, and charging of the flight battery is prohibited, so that the current demand of the land load can be met when the output current is small.
