[0024] To make the objectives, technical solutions, and advantages of the embodiments of the application clearer, the technical solutions of the application will be described below in connection with the embodiments. Obviously, the described embodiments are only some, but not all, of the embodiments of the application. Based on the embodiments of the application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of the application.

[0025] Currently, the related art provides contact charging, which is relatively low in efficiency. When a UAV is still performing a task, but the battery is insufficient to support the UAV to continue performing the task, the UAV has to return to the automatic airport for charging. The contact charging generally takes more than half an hour to charge to more than 60% of the battery capacity before the UAV can take off again. In addition, if the battery is not used for a long time and needs to be discharged to the battery storage voltage, but needs to perform a task during the storage voltage period, the endurance time will be greatly reduced, at least half of the endurance time. The related art also provides a polling charging and discharging system. For example, there are four batteries, and the polling charging and discharging system will intelligently poll the four batteries for charging and discharging. In the case of using networked UAVs and automatic airport deployment, the battery charging method will seriously affect the task execution efficiency. For example, if all four batteries in the automatic airport are in a depleted state, only one battery can be charged at a time, and if multiple UAVs land in the airport to take full batteries, it will not be possible to provide full batteries for the UAVs at any time.

[0026] Based on this, the application provides a battery control method, device, system, and computer readable storage medium, which can effectively protect the battery and effectively improve the problem of low UAV task execution efficiency caused by battery charging and discharging.

[0027] To facilitate the understanding of the embodiments, first, a battery control method disclosed by the embodiments of the application is described in detail. The method is applied to a control terminal in a battery control system, and the battery control system further includes multiple alternative batteries and multiple alternative charging and discharging structures. Referring to FIG. 1, the battery control system includes a control terminal 100, multiple alternative batteries 200, and multiple alternative charging and discharging structures 300. Figure 1A flowchart of a battery control method is shown. The method mainly includes the following steps S102 to S106:

[0028] In step S102, a start instruction for a target work device is received, and it is determined whether the candidate battery meets the preset start condition corresponding to the target work device. The target work device can include a work device such as a drone or a robot. If the target work device is a drone, the start instruction is a take-off instruction, and the preset start condition is used to limit the battery state and the battery remaining capacity value of the candidate battery. The candidate battery can be a BMS (Battery Management System) battery. For example, if a take-off instruction for a drone is received, it is determined whether the battery state and the battery remaining capacity value of each candidate battery meet the preset start condition corresponding to the drone, so as to select a candidate battery that meets the preset start condition.

[0029] In step S104, if so, a first target battery is determined from the candidate batteries that meet the preset start condition, and the first target battery is loaded into the target work device. For example, if there is only one candidate battery that meets the preset start condition, the candidate battery is used as the first target battery, and the first target battery is loaded into the drone so that the drone can work. If there are multiple candidate batteries that meet the preset start condition, one of the candidate batteries that meet the preset start condition is randomly selected as the first target battery, and the first target battery is loaded into the drone so that the drone can work.

[0030] In step S106, a first target charging and discharging structure is determined from the candidate charging and discharging structures, and each first target charging and discharging structure is controlled to perform a charging operation on the candidate batteries other than the first target battery until a preset charging end condition is met. The candidate charging and discharging structure includes a charger and a discharger, and the preset charging end condition can include that the battery remaining capacity value is greater than or equal to a first preset capacity threshold. In an optional embodiment, the candidate battery and the candidate charging and discharging structure can correspond to each other. For the candidate batteries that are not selected, the candidate charging and discharging structure corresponding to each battery can be determined as the first target charging and discharging structure, and the charger in the first target charging and discharging structure is used to charge the corresponding candidate battery. Assuming that the preset charging end condition is that the battery is fully charged (i.e., the battery remaining capacity is 100%), the charging operation can be stopped when the candidate battery is fully charged.

[0031] The battery control method provided by the embodiment of the present application provides a plurality of independent alternative batteries and a plurality of independent alternative charge-discharge structures, after receiving a starting instruction, the plurality of first target charge-discharge structures are controlled to perform a charging operation on the other alternative batteries except the first target battery, so that when the next starting instruction is received, there is still a target battery in the alternative batteries that meets the preset starting condition, thereby realizing uninterrupted operation of the target working device. The embodiment of the present application not only can effectively protect the battery, but also can effectively improve the problem of low task execution efficiency of the working device caused by battery charging and discharging.

[0032] For the foregoing step S102, the embodiment of the present application provides an implementation mode for judging whether the alternative battery meets the preset starting condition corresponding to the target working device. For each alternative battery, if the battery state of the alternative battery is battery health, and the battery remaining capacity of the alternative battery is greater than a third preset capacity threshold, it is determined that the battery meets the preset starting condition corresponding to the target working device. Illustratively, the battery state includes battery temperature, SOC (state of charge estimation), SOH (state of health estimation), SOS (safety state estimation), SOF (function state estimation) and SOE (available energy state estimation), and a threshold corresponding to each battery state can be set, and the current battery state of the alternative battery is compared with the corresponding threshold to evaluate whether the current battery state of the alternative battery is healthy. In addition, the third capacity threshold can be determined based on the task to be performed by the unmanned aerial vehicle. Optionally, the third capacity threshold can be positively correlated with the task duration. Illustratively, assuming that the battery control system is configured with four independent alternative batteries, namely, battery a1, battery a2, battery a3 and battery a4, if the battery states of the battery a1, the battery a2, the battery a3 and the battery a4 are all healthy, and the current remaining capacity values of the battery a1 and the battery a2 are greater than or equal to the third preset capacity threshold, and the current remaining capacity values of the battery a3 and the battery a4 are less than the third preset capacity threshold, it is determined that the battery a1 and the battery a2 meet the preset starting condition. At this time, the first target battery can be randomly determined from the battery a1 and the battery a2, and the chargers in the alternative charge-discharge structures corresponding to the battery a2, the battery a3 and the battery a4 are controlled to perform a charging operation on the above-mentioned batteries until the battery a2, the battery a3 and the battery a4 are fully charged.

[0033] The embodiment of the present application also provides an implementation mode if none of the alternative batteries meets the preset starting condition, see steps 1 to 3 as follows:

[0034] Step 1, if none of the alternative batteries meets the preset starting condition, each alternative charging and discharging structure is regarded as a second target charging and discharging structure. For example, assuming that the battery control system is configured with four independent alternative batteries, i.e., battery a1, battery a2, battery a3 and battery a4, and none of the battery a1, battery a2, battery a3 and battery a4 meets the preset starting condition, the alternative charging and discharging structure corresponding to each of the battery a1, battery a2, battery a3 and battery a4 is determined as a second target charging and discharging structure.

[0035] Step 2, the charging operation of each second target charging and discharging structure is controlled to be performed on each alternative battery until the preset charging end condition is met. In an embodiment, the charger in each second target charging and discharging structure can be controlled to perform the charging operation on the corresponding battery, and the charging operation is stopped when the preset charging end condition is met, such as when the battery is fully charged.

[0036] Step 3, when the end of the charging operation is detected, a second target battery is randomly determined from the alternative batteries to be loaded to the target working device. In an embodiment, if the battery states of the battery a1, battery a2, battery a3 and battery a4 all show healthy, after the charging is completed, one of the battery a1, battery a2, battery a3 and battery a4 is randomly selected as a second target battery, and the second target battery is loaded to the UAV to make the UAV work. Since each battery is equipped with a corresponding charging and discharging structure in the present application, compared with the polling charging and discharging system in the prior art which sequentially charges the batteries, the embodiment of the present application can simultaneously control each charging and discharging structure to charge multiple batteries, thereby significantly improving the overall efficiency of battery charging and avoiding the influence of battery charging on the efficiency of the UAV performing work.

[0037] Considering that the long-term full charge of the battery will have a negative impact on its service life, the embodiment of the present application further provides a discharging logic, as shown in steps a to d:

[0038] Step a, if a target instruction is received, it is judged whether the target instruction is received again within a preset time period; wherein the target instruction at least includes a starting instruction. For example, assuming that the preset time period is 3 days, when a take-off or return target instruction is received, the 3-day timing is started, and it is listened whether the take-off or return target instruction is received again within 3 days.

[0039] Step b, if no, the charging operation of each alternative charging and discharging structure is controlled to be performed on each alternative battery until the preset charging end condition is met. For example, if the take-off or return target instruction is not received again within 3 days, the charging operation of each alternative charging and discharging structure on each alternative battery is controlled, and the charging operation is stopped when the battery is fully charged.

[0040] Step c, when the end of the charging operation is detected, randomly selecting a plurality of third target batteries from the alternative batteries, and selecting a plurality of third target charge-discharge structures from the alternative charge-discharge structures. Wherein the number of third target batteries is consistent with the number of third target charge-discharge structures. Assuming that the battery control system is configured with 4 independent alternative batteries, that is, including battery a1, battery a2, battery a3 and battery a4, at the end of the charging operation, 2 third target batteries can be randomly selected from the 4 independent alternative batteries, and the corresponding alternative charge-discharge structure is used as the third target charge-discharge structure. For example, assuming that battery a2 and battery a3 are randomly selected as the third target battery, the alternative charge-discharge structure corresponding to battery a2 and battery a3 is used as the third target charge-discharge structure.

[0041] Step d, controlling each third target charge-discharge structure to perform a discharging operation on each third target battery until a preset discharging end condition is met. Wherein the preset discharging end condition includes that the battery remaining capacity value is greater than the second preset capacity threshold and less than the first preset capacity threshold, such as the battery remaining capacity is 50% (that is, half-electric state). For example, the discharger in the alternative charge-discharge structure corresponding to battery a2 is controlled to perform a discharging operation on battery a2 until battery a2 is in a half-electric state; similarly, the discharger in the alternative charge-discharge structure corresponding to battery a3 is controlled to perform a discharging operation on battery a3 until battery a3 is in a half-electric state.

[0042] In order to facilitate the understanding of the foregoing embodiments, the present embodiment exemplarily provides an application example of a battery control method, referring to Figure 2 The structure diagram of a battery control system is shown. The battery control system includes a master control system (that is, the above-mentioned control terminal), 4 chargers, 4 dischargers and 4 BMS batteries. The battery control system provided by the present embodiment is equipped with 4 independent sets of chargers and dischargers. The charger and discharger hardware corresponding to each battery exist independently and can be used independently without affecting each other. The present embodiment can realize independent charging and discharging operations of multiple batteries. The service life of a semi-solid lithium battery is 300 times of charging and discharging. The battery cannot be stored in a full-electric state for a long time, which will shorten the service life of the battery. Therefore, the hangar needs to actively manage the charging and discharging of the battery. The automatic airport needs to ensure that there is always a full-electric battery for the use of unmanned aerial vehicles. Therefore, at least 2 full-electric batteries are guaranteed in the hangar.

[0043] On the basis of the foregoing Figure 2 , the present embodiment provides another flow diagram of a battery control method as shown in Figure 3 The method mainly includes the following steps S302 to S306:

[0044] Step S302, receiving a take-off instruction.

[0045] Step S304, selecting full batteries from the alternative batteries.

[0046] Step S306, sending a charging instruction to all alternative batteries to ensure 4 full batteries.

[0047] On the basis of the foregoing Figure 2 , the embodiment of the present application provides another battery control method for discharging logic, as shown in the flow diagram of the battery control method, which mainly includes the following steps S402 to S406: Figure 4

[0048] Step S402, counting down 3 days.

[0049] Step S404, sending a charging instruction to all alternative batteries.

[0050] Step S406, selecting 2 full batteries to discharge to obtain 2 half batteries and 2 full batteries.
