[0100] The power system of this application can allocate energy through different energy management strategies according to the state of charge of the battery and the user's needs. For example, in most user scenarios, the demand for pure electric range and driving power is small, so the cooperation of "land travel battery + hybrid electric drive + engine" can meet the requirements. When the user occasionally needs a longer pure electric range or a larger driving power, the flying battery is connected to the power system by closing the relay of the buck-boost DC converter, which can not only meet the user's needs but also effectively protect the life of the flying battery.

[0106] The following Table 1 shows different

[0107] Table 1

[0108] The usage strategies of energy and power in different strategies are described by way of example below. The energy management strategy is exemplified by the "Terrestrial Travel Energy Management Strategy" but is not limited thereto.

[0109] Strategy 1:

[0110] When the terrestrial travel battery power is higher than the terrestrial travel battery target SOC and the flight battery power is higher than or equal to the flight battery target SOC, if in a usage scenario with a short mileage requirement, determine the first strategy.

[0111] The first strategy includes preferentially using the terrestrial travel battery power for driving until the terrestrial travel battery power reaches the terrestrial travel battery target SOC, where:

[0112] If the required power of the power system is less than the maximum power of the terrestrial travel battery, preferentially use the terrestrial travel battery to provide power; or, if the required power of the power system is greater than the maximum power of the terrestrial travel battery but less than the sum of the maximum power of the terrestrial travel battery and the maximum power generation of the engine through the hybrid electric drive, use the maximum power of the terrestrial travel battery to provide power, and the engine generates electricity through the hybrid electric drive to supplement the power; or, if the required power of the power system is greater than the sum of the maximum power of the terrestrial travel battery and the maximum power generation of the engine through the hybrid electric drive, use the maximum power of the terrestrial travel battery and the maximum power generation of the engine through the hybrid electric drive together to provide power, and the flight battery supplements the power.

[0113] That is to say, the power system preferentially uses the terrestrial travel battery power for driving until the terrestrial travel battery power reaches the set terrestrial travel battery target SOC.

[0114] When the required power is less than the maximum power of the terrestrial travel battery, the power system preferentially uses the terrestrial travel battery to meet the power requirement;

[0115] When the required power is greater than the maximum power of the terrestrial travel battery but less than the maximum power of the terrestrial travel battery + the maximum power generation of the engine through the hybrid electric drive, the power system preferentially uses the maximum power of the terrestrial travel battery, and the insufficient part is supplemented by the engine generating electricity through the hybrid electric drive;

[0116] When the required power is greater than the maximum power of the terrestrial travel battery + the maximum power generation of the engine through the hybrid electric drive, the power system preferentially uses the maximum power of the terrestrial travel battery + the maximum power generation of the engine through the hybrid electric drive, and the insufficient part is supplemented by the flight battery after the boost - buck DC - DC converter relay is engaged.

[0117] Among them, regarding the insufficient part being supplemented by the flight battery after the boost - buck DC - DC converter relay is engaged, reference can be made to Figure 5 and Figure 6As shown, the flight battery is connected to the land driving system through a converter (buck-boost DC converter) to supplement power for the land driving system by the flight battery; or, the flight battery is connected to the land driving system through a converter (buck-boost DC converter), and the power of the flight battery is boosted before supplementing power for the land driving system.

[0118] Strategy two:

[0119] When the land battery power is equal to the land battery target SOC and the flight battery power is higher than the flight battery target SOC, if in the usage scenario with a short mileage requirement, determine the second strategy.

[0120] When the land battery power is equal to the land battery target SOC and the flight battery power is equal to the flight battery target SOC, determine the second strategy.

[0121] The second strategy includes preferentially using hybrid power for driving, and maintaining the land battery power at the land battery target SOC, where: if the required power of the power system is less than the maximum power generation of the engine through the hybrid electric drive, use the engine and the land battery to provide power; or, if the required power of the power system is greater than the maximum power generation of the engine through the hybrid electric drive but less than the sum of the maximum power of the land battery and the maximum power generation of the engine through the hybrid electric drive, use the maximum power generation of the engine through the hybrid electric drive to provide power, and the land battery supplements power; or, if the required power of the power system is greater than the sum of the maximum power of the land battery and the maximum power generation of the engine through the hybrid electric drive, use the maximum power of the land battery and the maximum power generation of the engine through the hybrid electric drive together to provide power, and the flight battery supplements power.

[0122] That is to say, the power system preferentially uses hybrid power for driving, and the land battery power is maintained near the set land battery target SOC.

[0123] When the required power is less than the maximum power generation of the engine through the hybrid electric drive, the power system distributes the power of the engine and the land battery according to the "vehicle speed" and the "difference between the land battery power and the set target SOC"; the distribution ratio or distribution method can be set as needed, and this application does not limit it;

[0124] When the required power is greater than the maximum power generation of the engine through the hybrid electric drive but less than the maximum power of the land battery + the maximum power generation of the engine through the hybrid electric drive, the power system preferentially uses the maximum power generation of the engine through the hybrid electric drive to generate electricity, and the insufficient part is supplemented by the land battery;

[0125] When the required power is greater than the maximum power of the land battery + the maximum power generation of the engine through the hybrid electric drive, the power system preferentially uses the maximum power of the land battery + the maximum power generation of the engine through the hybrid electric drive to provide power, and the insufficient part is supplemented by the flight battery after the buck-boost DC converter relay is engaged.

[0126] Among them, regarding the insufficient part being supplemented by the flight battery after the buck-boost DC converter relay is engaged, reference can be made to Figure 5 and Figure 6 As shown, the flight battery is connected to the land power system through a converter (buck-boost DC converter), and the flight battery supplies power to the land power system; or, the flight battery is connected to the land power system through a converter (buck-boost DC converter), and the power of the flight battery is boosted and then supplied to the land power system to supplement power.

[0127] Strategy three:

[0128] When the power level of the land battery is lower than the target SOC of the land battery and the power level of the flight battery is higher than the target SOC of the flight battery, if it is in a usage scenario with a short mileage requirement, the third strategy is determined.

[0129] When the power level of the land battery is lower than the target SOC of the land battery and the power level of the flight battery is equal to the target SOC of the flight battery, the third strategy is determined.

[0130] The third strategy includes preferentially using hybrid power for driving, and the power level of the land battery is gradually charged up to the target SOC of the land battery, where: if the required power of the power system is less than the maximum power generation of the engine through the hybrid electric drive, the engine generates electricity through the hybrid electric drive and the land battery provide power; or, if the required power of the power system is greater than the maximum power generation of the engine through the hybrid electric drive but less than the sum of the maximum power of the land battery and the maximum power generation of the engine through the hybrid electric drive, the maximum power generation of the engine through the hybrid electric drive is used to provide power, and the land battery supplements the power; or, if the required power of the power system is greater than the sum of the maximum power of the land battery and the maximum power generation of the engine through the hybrid electric drive, the maximum power of the land battery and the maximum power generation of the engine through the hybrid electric drive are used together to provide power, and the flight battery supplements the power.

[0131] That is to say, the power system preferentially uses hybrid power for driving, and the power level of the land battery is gradually charged up to the set target SOC of the land battery.

[0132] When the required power is less than the maximum power generation of the engine through the hybrid electric drive, the power system distributes the power of the engine and the land battery according to the "vehicle speed" and the "difference between the power level of the land battery and the set target SOC"; the distribution ratio or distribution method thereof can be set as needed, and this application does not limit it;

[0133] When the required power is greater than the maximum power generation of the engine through the hybrid electric drive but less than the maximum power of the land battery + the maximum power generation of the engine through the hybrid electric drive, the power system preferentially uses the maximum power generation of the engine through the hybrid electric drive to provide power, and the insufficient part is supplemented by the land battery;

[0134] When the required power is greater than the maximum power of the land battery + the maximum power generation of the engine through the hybrid electric drive, the power system preferentially uses the maximum power of the land battery + the maximum power generation of the engine through the hybrid electric drive to provide power, and the insufficient part is supplemented by the flight battery after the boost-buck DC converter relay is engaged.

[0135] Among them, regarding the insufficient part being supplemented by the flight battery after the boost-buck DC converter relay is engaged, reference can be made to Figure 5 and Figure 6 As shown, the flight battery is connected to the land power system through a converter (boost-buck DC converter), and the flight battery supplies power to the land power system; or, the flight battery is connected to the land power system through a converter (boost-buck DC converter), and the power of the flight battery is boosted and then supplied to the land power system to supplement power.

[0136] Strategy Four:

[0137] When the power level of the land battery is higher than the target SOC of the land battery and the power level of the flight battery is lower than the target SOC of the flight battery, the fourth strategy is determined.

[0138] The fourth strategy includes preferentially using the power level of the land battery for driving, and at the same time, the land battery supplements the power of the flight battery to reach the target SOC of the flight battery until the power level of the land battery reaches the target SOC of the land battery, where: if the required power of the power system is less than the maximum power of the land battery, the land battery is preferentially used to provide power; or, if the required power of the power system is greater than the maximum power of the land battery but less than the sum of the maximum power of the land battery and the maximum power generation of the engine through the hybrid electric drive, the maximum power of the land battery is used to provide power, and the engine generates electricity through the hybrid electric drive to supplement the power; or, if the required power of the power system is greater than the sum of the maximum power of the land battery and the maximum power generation of the engine through the hybrid electric drive, the maximum power of the land battery and the maximum power generation of the engine through the hybrid electric drive are used together to provide power, and the flight battery supplements the power.

[0139] That is to say, the power system preferentially uses the power level of the land battery for driving, and at the same time, the land battery supplements the power of the flight battery through the boost-buck DC converter to reach the target SOC of the flight battery until the power level of the land battery reaches the set target SOC of the land battery.

[0140] When the required power is less than the maximum power of the land battery, the power system preferentially uses the land battery to meet the power demand;

[0141] When the required power is greater than the maximum power of the land battery but less than the maximum power of the land battery + the maximum power generation of the engine through the hybrid electric drive, the power system preferentially uses the maximum power of the land battery to provide power, and the insufficient part is supplemented by the engine generating electricity through the hybrid electric drive;

[0142] When the required power is greater than the maximum power of the land battery + the maximum power generation of the engine through the hybrid electric drive, the power system preferentially uses the maximum power of the land battery + the maximum power generation of the engine through the hybrid electric drive to provide power, and the insufficient part is supplemented by the flight battery after the buck-boost DC converter relay is engaged.

[0143] Among them, regarding the insufficient part being supplemented by the flight battery after the buck-boost DC converter relay is engaged, reference can be made to Figure 5 and Figure 6 As shown, the flight battery is connected to the land power system through a converter (buck-boost DC converter), and the flight battery supplies power to the land power system; or, the flight battery is connected to the land power system through a converter (buck-boost DC converter), and the power of the flight battery is boosted and then supplied to the land power system to supplement power.

[0144] Strategy Five:

[0145] When the power of the land battery is equal to the target SOC of the land battery and the power of the flight battery is lower than the target SOC of the flight battery, the fifth strategy is determined.

[0146] The fifth strategy includes preferentially using hybrid power for driving, maintaining the power of the land battery at the target SOC of the land battery, and simultaneously charging the flight battery to reach the target SOC of the flight battery, where: if the required power of the power system is less than the maximum power generation of the engine through the hybrid electric drive, use the engine to generate electricity through the hybrid electric drive and the land battery to provide power; or, if the required power of the power system is greater than the maximum power generation of the engine through the hybrid electric drive but less than the sum of the maximum power of the land battery and the maximum power generation of the engine through the hybrid electric drive, use the maximum power generation of the engine through the hybrid electric drive to provide power, and the land battery supplements the power; or, if the required power of the power system is greater than the sum of the maximum power of the land battery and the maximum power generation of the engine through the hybrid electric drive, use the maximum power of the land battery and the maximum power generation of the engine through the hybrid electric drive together to provide power, and the flight battery supplements the power.

[0147] That is to say, the power system preferentially uses hybrid power for driving, maintains the power of the land battery near the set target SOC of the land battery, and simultaneously charges the flight battery to reach the target SOC of the flight battery through the buck-boost DC converter.

[0148] When the required power is less than the maximum power generation of the engine through the hybrid electric drive, the power system distributes the power of the engine and the ground travel battery according to the "vehicle speed" and the "difference between the ground travel battery power and the set target SOC"; the distribution ratio or distribution method can be set as needed, and this application does not limit it;

[0149] When the required power is greater than the maximum power generation of the engine through the hybrid electric drive but less than the maximum power of the ground travel battery + the maximum power generation of the engine through the hybrid electric drive, the power system preferentially uses the maximum power generation of the engine through the hybrid electric drive to provide power, and the insufficient part is supplemented by the ground travel battery;

[0150] When the required power is greater than the maximum power of the ground travel battery + the maximum power generation of the engine through the hybrid electric drive, the power system preferentially uses the maximum power of the ground travel battery + the maximum power generation of the engine through the hybrid electric drive to provide power, and the insufficient part is supplemented by the flight battery after the boost-buck DC converter relay is engaged.

[0151] Among them, regarding the insufficient part being supplemented by the flight battery after the boost-buck DC converter relay is engaged, reference can be made to Figure 5 and Figure 6 As shown, the flight battery is connected to the ground power system through a converter (boost-buck DC converter), and the flight battery supplies power to the ground power system; or, the flight battery is connected to the ground power system through a converter (boost-buck DC converter), and the power of the flight battery is boosted and then supplied to the ground power system to supplement power.

[0152] Strategy Six:

[0153] When the ground travel battery power is lower than the ground travel battery target SOC and the flight battery power is lower than the flight battery target SOC, the sixth strategy is determined.

[0154] The sixth strategy includes preferentially using hybrid power for driving, gradually charging the ground travel battery power to the ground travel battery target SOC, and gradually charging the flight battery power to the set flight battery target SOC, where: if the required power of the power system is less than the maximum power generation of the engine through the hybrid electric drive, use the engine to generate power through the hybrid electric drive and the ground travel battery to provide power; or, if the required power of the power system is greater than the maximum power generation of the engine through the hybrid electric drive but less than the sum of the maximum power of the ground travel battery and the maximum power generation of the engine through the hybrid electric drive, use the maximum power generation of the engine through the hybrid electric drive to provide power, and the ground travel battery supplements the power; or, if the required power of the power system is greater than the sum of the maximum power of the ground travel battery and the maximum power generation of the engine through the hybrid electric drive, use the maximum power of the ground travel battery and the maximum power generation of the engine through the hybrid electric drive together to provide power, and the flight battery supplements the power.

[0155] That is to say, the power system preferentially uses hybrid power for driving, and the power of the land battery and the flight battery is gradually charged up to their respective set target SOCs.

[0156] When the required power is less than the maximum power generation of the engine through the hybrid electric drive, the power system distributes the power of the engine and the land battery according to the "vehicle speed" and the "difference between the land battery power and the set target SOC"; the distribution ratio or distribution method can be set as needed, and this application does not limit it;

[0157] When the required power is greater than the maximum power generation of the engine through the hybrid electric drive but less than the maximum power of the land battery + the maximum power generation of the engine through the hybrid electric drive, the power system preferentially uses the maximum power generation of the engine through the hybrid electric drive to provide power, and the insufficient part is supplemented by the land battery;

[0158] When the required power is greater than the maximum power of the land battery + the maximum power generation of the engine through the hybrid electric drive, the power system preferentially uses the maximum power of the land battery + the maximum power generation of the engine through the hybrid electric drive to provide power, and the insufficient part is supplemented by the flight battery after the boost-buck DC converter relay is engaged.

[0159] Among them, regarding the insufficient part being supplemented by the flight battery after the boost-buck DC converter relay is engaged, reference can be made to Figure 5 and Figure 6 As shown, the flight battery is connected to the land power system through a converter (boost-buck DC converter) to supplement power for the land power system; or, the flight battery is connected to the land power system through a converter (boost-buck DC converter), and the power of the flight battery is boosted and then used to supplement power for the land power system.

[0160] Strategy Seven:

[0161] When the power of the land battery is higher than the land battery target SOC, and the power of the flight battery is higher than or equal to the flight battery target SOC, if it is in a usage scenario with a long mileage requirement, determine Strategy Seven.

[0162] When the power of the land battery is equal to the land battery target SOC, and the power of the flight battery is higher than the flight battery target SOC, if it is in a usage scenario with a long mileage requirement, determine Strategy Seven.

[0163] The seventh strategy includes preferentially using the land travel battery power for driving until the land travel battery power reaches the land travel battery target SOC, and then using the flight battery power for driving until the flight battery power reaches the flight battery target SOC, where: if the required power of the power system is less than the maximum power of the land travel battery, the land travel battery is preferentially used to provide power; or, if the required power of the power system is greater than the maximum power of the land travel battery but less than the sum of the maximum power of the land travel battery and the maximum power of the flight battery, the maximum power of the land travel battery is used to provide power, and the flight battery is used to supplement the power; or, if the required power of the power system is greater than the sum of the maximum power of the land travel battery and the maximum power of the flight battery, the maximum power of the land travel battery and the maximum power of the flight battery are used to provide power, and the engine is used to supplement the power through hybrid electric drive power generation.

[0164] That is to say, the power system preferentially uses the land travel battery power for driving until the land travel battery power reaches the set land travel battery target SOC, and then uses the flight battery power for driving through the buck-boost DC converter until the flight battery power reaches the set flight battery target SOC.

[0165] When the required power is less than the maximum power of the land travel battery, the power system preferentially uses the land travel battery to meet the power demand;

[0166] When the required power is greater than the maximum power of the land travel battery but less than the maximum power of the land travel battery + the maximum power of the flight battery, the power system preferentially uses the maximum power of the land travel battery, and the insufficient part is supplemented by the flight battery after the buck-boost DC converter relay is engaged;

[0167] When the required power is greater than the maximum power of the land travel battery + the maximum power of the flight battery, the power system preferentially uses the maximum power of the land travel battery + the maximum power of the flight battery, and the insufficient part is supplemented by the engine through hybrid electric drive power generation.

[0168] Among them, regarding the insufficient part being supplemented by the flight battery after the buck-boost DC converter relay is engaged, reference can be made to Figure 5 and Figure 6 As shown, the flight battery is connected to the land travel power system through the converter (buck-boost DC converter), and the flight battery supplements the power for the land travel power system; or, the flight battery is connected to the land travel power system through the converter (buck-boost DC converter), and the power of the flight battery is boosted and then used to supplement the power for the land travel power system.

[0169] Strategy eight:

[0170] When the land travel battery power is lower than the land travel battery target SOC and the flight battery power is higher than the flight battery target SOC, if it is in a usage scenario with a long mileage demand, the eighth strategy is determined.

[0171] The eighth strategy includes preferentially using the power of the flight battery for driving, and simultaneously replenishing the land travel battery with power from the flight battery to reach the target SOC of the land travel battery until the power of the flight battery reaches the target SOC of the flight battery, where: If the required power of the power system is less than the maximum power of the flight battery, preferentially use the flight battery to provide power; or, if the required power of the power system is greater than the maximum power of the flight battery but less than the sum of the maximum power of the flight battery and the maximum power generated by the engine through the hybrid electric drive, use the maximum power of the flight battery to provide power, and the engine generates electricity through the hybrid electric drive to supplement the power; or, if the required power of the power system is greater than the sum of the maximum power of the flight battery and the maximum power generated by the engine through the hybrid electric drive, use the maximum power of the flight battery and the maximum power generated by the engine through the hybrid electric drive together to provide power, and the land travel battery supplements the power.

[0172] That is to say, the power system preferentially uses the power of the flight battery through the buck-boost DC converter for driving, and simultaneously the flight battery replenishes the land travel battery with power through the buck-boost DC converter to reach the target SOC of the land travel battery until the power of the flight battery reaches the set target SOC of the flight battery.

[0173] When the required power is less than the maximum power of the flight battery, the power system preferentially uses the flight battery through the buck-boost DC converter to meet the power demand;

[0174] When the required power is greater than the maximum power of the flight battery but less than the maximum power of the flight battery + the maximum power generated by the engine through the hybrid electric drive, the power system preferentially uses the maximum power of the flight battery through the buck-boost DC converter, and the insufficient part is supplemented by the engine generating electricity through the hybrid electric drive;

[0175] When the required power is greater than the maximum power of the flight battery + the maximum power generated by the engine through the hybrid electric drive, the power system preferentially uses the maximum power of the flight battery + the maximum power generated by the engine through the hybrid electric drive to provide power, and the insufficient part is supplemented by the land travel battery.

[0176] Among them, the insufficient part is supplemented by the land travel battery, which can refer to Figure 7 and Figure 8 As shown, the flight battery and the land travel power system are connected through a converter (buck-boost DC converter), and the land travel power system supplements power for the flight battery; or, the flight battery and the land travel power system are connected through a converter (buck-boost DC converter), and the power of the land travel power system is boosted and then used to supplement power for the flight battery.

[0177] Figure 10 It is another process schematic diagram of the flight vehicle power processing method shown in the embodiments of the present application.

[0178] The power system of this application can externally charge and replenish the battery through different energy replenishment strategies according to the user's requirements for future target scenarios. For most future target scenarios of users, such as in future usage scenarios, if only land travel is involved, generally only the land travel battery needs to be replenished, thus avoiding the lifespan attenuation caused by the frequent full charge of the flight battery; while when the user occasionally needs to fly in future usage scenarios, the flight battery can be replenished by engaging the relay of the buck-boost DC converter, thus meeting the user's future flight needs.

[0179] See Figure 10 , the method includes:

[0181] Among them, the preset parameter can be the flight battery power and the flight battery lifespan protection SOC, and the comparison result of the preset parameter can include the following situations: 1) The flight battery power is higher than or equal to the flight battery lifespan protection SOC; the flight battery power is lower than the flight battery lifespan protection SOC.

[0182] S1002. According to the comparison result between the flight battery power and the flight battery lifespan protection SOC, and according to the future target scenario, determine the external charging and energy replenishment strategy of the power system for managing the energy replenishment of the land travel battery and the flight battery according to the external charging and energy replenishment strategy.

[0183] Among them, it can be when the flight battery power is higher than or equal to the flight battery lifespan protection SOC,

[0184] If the future target scenario is a scenario of only land travel, determine the first energy replenishment strategy, and the first energy replenishment strategy includes: preferentially replenish the land travel battery, and end the replenishment when the land travel battery power reaches the upper limit; or,

[0185] If the future target scenario is a scenario of flying, determine the third energy replenishment strategy, and the third energy replenishment strategy includes: preferentially replenish the flight battery, then replenish the land travel battery when the flight battery power reaches the upper limit, and end the replenishment when the land travel battery also reaches the upper limit.

[0186] Among them, it can be when the flight battery power is lower than the flight battery lifespan protection SOC,

[0189] The following Table 2 shows different energy replenishment strategies given for different flight battery states and user requirements.

[0190]

[0191] Table 2

[0192] Energy replenishment strategy one:

[0193] When the flight battery's power is higher than or equal to the flight battery life protection SOC, if the future target scenario is a scenario where only land travel will occur, determine the first energy replenishment strategy.

[0194] The first energy replenishment strategy includes: giving priority to replenishing the land travel battery. When the land travel battery reaches its upper limit, the energy replenishment ends.

[0195] That is to say, the power system gives priority to replenishing the land travel battery. When the land travel battery reaches its upper limit, the energy replenishment ends.

[0196] Energy replenishment strategy two:

[0197] When the flight battery's power is lower than the flight battery life protection SOC, if the future target scenario is a scenario where only land travel will occur, determine the second energy replenishment strategy.

[0198] The second energy replenishment strategy includes: giving priority to replenishing the land travel battery. When the land travel battery reaches its upper limit, use a converter to replenish the flight battery. When the flight battery reaches the flight battery life protection SOC, the energy replenishment ends.

[0199] That is to say, the power system gives priority to replenishing the land travel battery. When the land travel battery reaches its upper limit, use a buck-boost DC converter to replenish the flight battery. When the flight battery reaches the life protection SOC, the energy replenishment ends.

[0200] Energy replenishment strategy three:

[0201] When the flight battery's power is higher than or equal to the flight battery life protection SOC, if the future target scenario is a scenario where flight will occur, determine the third energy replenishment strategy.

[0202] When the flight battery's power is lower than the flight battery life protection SOC, if the future target scenario is a scenario where flight will occur, determine the third energy replenishment strategy.

[0203] The third energy replenishment strategy includes: preferentially replenishing energy for the flight battery, replenishing energy for the land travel battery when the flight battery reaches its upper limit, and ending the energy replenishment when the land travel battery also reaches its upper limit.

[0204] That is to say, the power system preferentially replenishes energy for the flight battery, replenishes energy for the land travel battery when the flight battery reaches its upper limit, and ends the energy replenishment when the land travel battery also reaches its upper limit.

[0205] It should be noted that the power system of the embodiments of the present application can also be applied to any vehicle, such as a flying car, a smart car, etc.

[0206] It should also be noted that the "land travel energy management strategy" and "charging energy replenishment energy management strategy" of the power system of the embodiments of the present application can be applied to any power system including two power batteries. The power system of the embodiments of the present application can meet the usage requirements of a two-part flying car. The embodiments of the present application adopt a scheme of "engine + hybrid electric drive + buck-boost DC converter + two power batteries", where the land travel battery with a relatively high cycle life can cooperate with the "engine + hybrid electric drive" to meet most of the land travel scenarios of users, while the flight battery with both large energy density and power density can meet the flight requirements of the flying body.

[0207] The "land travel energy management strategy" of the embodiments of the present application meets the needs of users for different land travel scenarios on the premise of protecting the life of the flight battery as much as possible: in most land travel scenarios of users, the demand for pure electric mileage and driving power is relatively small, so generally the cooperation of "engine + hybrid electric drive + land travel battery" can meet the needs. When users occasionally need a longer pure electric mileage or a larger driving power, the relay of the buck-boost DC converter can be closed to connect the flight battery to the system, which can not only meet the needs of users but also effectively reduce the usage times of the flight battery and protect the life of the flight battery.

[0208] The "charging energy replenishment energy management strategy" of the embodiments of the present application meets different future usage scenarios of users on the premise of protecting the life of the flight battery as much as possible: in most future usage scenarios of users, they generally travel on land, so generally replenishing energy for the land travel battery can avoid the life attenuation caused by the flight battery being often fully charged; when users occasionally need to fly in the future, the relay of the buck-boost DC converter can be engaged to replenish energy for the flight battery, so as to meet the future flight needs of users.
