SOC in table 1 represents the state of charge, which reflects the remaining capacity of the battery, and is numerically defined as the ratio of the remaining capacity to the battery capacity, expressed in percent. The value range of the battery charging indicator is 0-1, when the SOC is 0, the battery is completely discharged, and when the SOC is 1, the battery is completely charged. The first bar indicates different temperature values, such as 0 ℃, 5 ℃, 10 ℃, 25 ℃ and the like.
Wherein, the output power capability values of the battery under different temperature values and different state of charge values are recorded in table 1. For example, when the state of charge is 100% and the battery temperature is 25 ℃, the corresponding SOP is 2795, which means that the maximum SOP that can be output by the battery is 2795 when the state of charge is 100% and the battery temperature is 25 ℃; for another example, when the state of charge is 60% and the battery temperature is 25 ℃, the corresponding SOP is 1762, which means that the maximum SOP that can be output when the battery is 60% and the battery temperature is 25 ℃ is 1762.
The existing batteries Of mobile platforms, such as aircraft, all use a fixed output Power (SOP). However, in practical applications, the weight of the aircraft is not fixed, such as carrying loads of different weights. For aircraft with uncertain weight, if the fixed SOP is still adopted, the flight of the aircraft is more limited, and in severe cases, the situation of falling and exploding can occur.
For example, because the condition is special, the load that industrial unmanned aerial vehicle carried on is unfixed, and the weight of different loads is also different, and then leads to same industrial unmanned aerial vehicle when operation each time, its weight is also different. When the weights are different, if the power of the unmanned aerial vehicle is controlled by the fixed SOP, the limited power of the battery cannot be exerted, and even the phenomenon of crash and explosion occurs.
For example, if the takeoff power of the unmanned aerial vehicle when it is unloaded is 800W, the takeoff power of the unmanned aerial vehicle when it is fully loaded may reach 1800W, and the takeoff power is greatly different under different loading conditions. If a fixed SOP is still used, such as setting the battery SOP at 1800W, the aircraft may be too restrained, and if the battery SOP is set at 800W, the aircraft may crash into an aircraft.
Therefore, the embodiment of the application provides a battery control method, an intelligent battery, a movable platform, a movable assembly and a storage medium, wherein the battery control method can be applied to the intelligent battery or the movable platform, the output power of the battery can be dynamically adjusted according to the weight of the movable platform, the utilization efficiency of the battery can be improved, and the operation safety of the movable platform can be ensured.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating steps of a battery control method according to an embodiment of the present disclosure. The battery control method is applied to a battery and used for supplying power to a movable platform.
As shown in fig. 2, the battery control method includes steps S101 to S103.
S101, acquiring the weight of the movable platform and/or the load carried by the movable platform.
When the movable platform runs, the weight of the movable platform and/or the load carried by the movable platform is acquired. Wherein the weight includes a specific weight value or weight range, the specific weight value is, for example, 7Kg, and the weight range is, for example, 6.9Kg to 7.1 Kg. The movable platform runtime can include the startup runtime and the running process. Specifically, the weight of the movable platform, the weight of the load carried by the movable platform, or the weight of the movable platform and the load carried by the movable platform may be acquired.
For example, the weight of unmanned aerial vehicle's fuselage is 5Kg, has carried on sprinkler, and this sprinkler's weight is 3 Kg. Then the weight of the unmanned aerial vehicle is 5Kg, the weight of the load carried by the unmanned aerial vehicle is 3Kg, and the weight of the unmanned aerial vehicle and the load carried by the unmanned aerial vehicle is 8 Kg. The weight of the load carried by the unmanned aerial vehicle is 3Kg, or the weight of the unmanned aerial vehicle and the load carried by the unmanned aerial vehicle can be 8 Kg.
In some cases, the weight of the same type of drone may also vary, but the weight of the load may be fixed, so the weight of the drone is obtained as a basis for adjusting the output power of the battery.
In one embodiment, in order to quickly and conveniently obtain the weight of the movable platform and/or the load carried by the movable platform, the operation power of the movable platform can be obtained; and determining the weight of the movable platform and/or the load carried by the movable platform according to the running power.
The operating power includes power corresponding to the movable platform when the movable platform operates, for example, the movable platform is an unmanned aerial vehicle, and the operating power includes takeoff power and/or hovering power. The operating power also includes a preset operating power for the movable platform, for example, a preset takeoff power and/or hover power.
The takeoff power can ensure that the unmanned aerial vehicle normally takes off, the takeoff power is related to the weight of the unmanned aerial vehicle, namely, positive correlation is formed, and therefore the weight of the unmanned aerial vehicle can be determined according to the takeoff power.
The hovering power can ensure that the unmanned aerial vehicle stably hovers in the air, the hovering power is related to the weight of the unmanned aerial vehicle, and is in positive correlation with the takeoff power, so that the weight of the unmanned aerial vehicle can be determined according to the takeoff power, the influence of other factors can be eliminated, and the weight of the unmanned aerial vehicle can be determined more accurately.
Specifically, the weight of the movable platform and/or the load carried by the movable platform may be determined according to the corresponding relationship or the fitting relationship between the operating power and the weight.
In some embodiments, the weight of the movable platform and/or the load carried by the movable platform is determined according to the operating power of the movable platform, specifically, a preset mapping relation table between the operating power and the weight is obtained; and determining the weight corresponding to the operating power of the movable platform as the weight of the movable platform and/or the load carried by the movable platform according to the preset mapping relation table. The weight of the movable platform can be quickly and accurately obtained through the mapping relation table.
In this embodiment, a preset mapping table between the operating power and the weight is stored in the smart battery, so as to obtain the corresponding weight according to the operating power.
In some embodiments, the preset mapping relationship table between the operating power and the weight records the corresponding relationship between different operating power ranges and different weights. Therefore, the operation power range corresponding to the operation power of the movable platform can be determined, and the weight corresponding to the determined operation power range is used as the weight of the movable platform and/or the load carried by the movable platform.
For example, an operating power range of 400W-420W corresponds to a weight of 7Kg, an operating power range of 645W-655W corresponds to a weight of 8Kg, an operating power range of 895W-905W corresponds to a weight of 9Kg, and an operating power range of 650W for the movable platform, for an operating power range of 645W-655W, may determine a weight of 8Kg for the movable platform.
The above-mentioned determination of the weight of the movable platform includes the total weight of the movable platform and its carrying load, but may of course also be the weight of the movable platform (without load) or only the weight of the load (the weight of the movable platform is substantially constant). The weight is determined in the same manner.
And S102, determining the target output power of the battery according to the movable platform and/or the weight of the load carried by the movable platform.
Specifically, different output powers of batteries corresponding to different weights of the movable platform are subjected to experimental tests to ensure the safety of the movable platform, so that target output powers of the batteries corresponding to different weights are obtained, the target output powers can improve the utilization efficiency of the batteries and ensure the safe operation of the movable platform.
Therefore, the target output power of the power supply battery of the movable platform can be determined according to the weight of the movable platform and/or the load carried by the movable platform.
In some embodiments, in order to determine the target output power of the battery quickly and accurately, a preset mapping relation table between the weight and the output power may be specifically obtained; and determining the output power corresponding to the weight of the movable platform and/or the load carried by the movable platform according to the preset mapping relation table to obtain the target output power of the battery.
The preset mapping relation table is obtained by testing in advance, and the corresponding relation between different weights and different output powers is recorded. And taking the output power obtained by inquiring according to the mapping relation table as the target output power, thereby quickly and accurately obtaining the target output power of the battery so as to control the battery according to the target output power.
In some embodiments, the target output power of the battery may be directly determined according to the weight of the movable platform and/or the load carried by the movable platform, and the target output power may be obtained by querying an output power capability table of the battery.
Inquiring an output power capability table of the battery to obtain the target output power, specifically determining a preset output power corresponding to the weight of the load carried by the movable platform and/or the movable platform; acquiring an output power capacity table of the battery, wherein the output power capacity table records output power capacity values of the battery under different temperature values and different charge state values; and inquiring an output power capacity value matched with preset output power from the output power capacity table to obtain the target output power of the battery.
The preset output power is power capable of ensuring the operation of the movable platform, and can be understood as minimum output power capable of ensuring the normal operation of the movable platform. The weight of the movable platform and/or the load carried by the movable platform is in positive correlation with the preset output power, namely the weight of the movable platform is increased, and the corresponding preset output power is also larger.
As shown in table 1, the output power capability table records output power capability values of the battery at different temperature values and different state of charge values.
For example, the weight of the unmanned aerial vehicle is 7KG, 8KG and 9KG, and the corresponding preset output power is 400W, 650W and 900W, respectively.
Inquiring an output power capacity value matched with the preset output power from the output power capacity table, for example, selecting an output power capacity value larger than the preset output power from the output power capacity table as the target output power of the battery; or, at a plurality of output power capability values greater than the preset output power, selecting the minimum output power capability value as the target output power of the battery.
For example, if the weight of the drone is 7Kg, and the preset output power of the drone is determined to be 400W, an output power capability value greater than 400W may be determined from table 1, where the output power capability value greater than 400W is, for example, 589, 493, 411, 572, 476, 466, 422, 578, 521, 442, 643, 496, 575, and 576.
In some embodiments, in order to obtain a more suitable target output power, the output power capability value with the smallest difference from the preset output power may be included in the output power capability table.
For example, the output power capability value of more than 400W is, for example, 589, 493, 411, 572, 476, 466, 422, 578, 521, 442, 643, 496, 575, and 576, and the output power capability value of 411 is selected as the target output power.
In some embodiments, in order to more accurately and reasonably query the output power capability table of the battery according to the preset output power to obtain the target output power, the current state of charge SOC of the battery may also be considered.
Specifically, the state of charge of the battery is acquired; determining a target state of charge value from a plurality of state of charge values of an output power capability table according to the state of charge of the battery; determining a plurality of output power capacity values corresponding to the target state of charge values; and selecting one output power capacity value from a plurality of output power capacity values corresponding to the target state of charge values as the target output power of the battery.
Wherein the target state of charge value is a state of charge value that is less than or equal to the state of charge of the battery.
For example, if the state of charge of the battery is 75%, a plurality of state of charge values such as 70%, 60%, 50%, 40%, 30%, 20%, and 15% may be determined in the output power capability table as the target state of charge values.
And determining a plurality of output power capacity values corresponding to the target state of charge values, wherein the output power capacity values are larger than the preset output power.
For example, the preset output power is 400W. The determined target state of charge value is 70%, and the corresponding output power capability values are 476 and 616, respectively; the determined target state of charge value is 50%, which corresponds to output power capability values of 466 and 633, respectively.
Specifically, one of the output power capability values 476 and 616 corresponding to a state of charge value of 70% may be selected as the target output power of the battery; alternatively, one of the output power capability values 466 and 633 corresponding to the state of charge value of 50% is selected as the target output power of the battery.
In some embodiments, in order to determine a more suitable target output power and improve the utilization efficiency of the battery, a minimum output power capability value may be specifically selected from a plurality of output power capability values corresponding to the target state of charge values as the target output power of the battery.
For example, the smallest output power capability value 466 is selected as the target output power of the battery from the output power capability values 466 and 633 corresponding to the state of charge value of 50%.
