Problems solved by technology

[0003] However, in the existing battery power consumption control scheme, generally only some functional modules of the battery are controlled to stop working, while the microprocessor is still working normally. This control method makes the overall power consumption of the battery still relatively high

Embodiment 1

[0063] figure 2 It is a schematic flow chart of the battery power consumption control method provided by the embodiment of the present invention, combined with figure 1 The technical solution in the first embodiment will be described together. Such as figure 2 As shown, the battery power control method includes:

[0064] Step S110: Determine that the battery is in a state of no charging current, no discharging current, and no communication.

[0065] In one embodiment, considering that the battery is working normally (such as normal charging, normal discharge or normal communication), if the fuel gauge 20 is controlled to enter the deep sleep mode, it will cause serious consequences (such as when the UAV is flying). 20 Entering the deep sleep mode will cause the consequences of crashing), so it is necessary to make sure that the battery is in a state of no charging current, no discharging current, and no communication. The charging current or discharging current of the ba...

Embodiment 2

[0078] see image 3 , in one embodiment, when the judgment result of step S130 in the first embodiment above is no, it also includes:

[0079] Step S150: Determine that the duration of the battery being in a state of no charging current, no discharging current, and no communication is greater than or equal to a second preset duration.

[0080] In one embodiment, considering that the battery needs to better preserve the power of the battery pack 10 during transportation or long-term storage, the battery can be kept in a state of no charging current, no discharging current, and no communication. When it is determined that the battery is in the state of no charging current, no discharging current, and no communication for a duration greater than or equal to the second preset duration, we can consider that the battery is in the process of transportation or long-term storage .

[0081] The second preset duration can be artificially set as reasonable data, such as 3 days, 7 days, ...

Embodiment 3

[0088] see Figure 4 , in one embodiment, the electrical performance parameter in the above-mentioned embodiment 2 also includes the cell voltage difference, before step S140 also includes:

[0089] Step S170: According to the electrical performance parameters, it is determined that the cell voltage difference is smaller than a third voltage threshold.

[0090] In this embodiment, the cell voltage difference that appears refers to the absolute value of the voltage difference between any two cells in the cell set 10, that is, the absolute value of the voltage difference between any two cells is less than the third voltage Thresholds are considered to meet the conditions.

[0091] In one embodiment, the third voltage threshold is 30 millivolts. Normally, when the cell voltage difference in the battery pack 10 is greater than 30 millivolts, it means that the battery pack 10 needs to be balanced, otherwise it is not suitable to enter the normal working state again.

[0092] It ...

Abstract

The invention relates to a battery power consumption control method and device and an unmanned aerial vehicle. The battery power consumption control method comprises the steps that a battery is determined to be in the state of no charging current, no discharging current and no communication; the electrical performance parameters of the battery are collected, wherein the electrical performance parameters comprise the minimum cell voltage of the battery; according to the electrical performance parameters, whether the minimum cell voltage is less than or equal to a first voltage threshold; and ifthe minimum cell voltage is less than or equal to the first voltage threshold, a voltameter and a microprocessor are controlled to start a deep sleep mode. According to the invention, the method usesdual-effect control of the voltameter and the microprocessor; the battery can achieve ultra-low power consumption under certain conditions; and the battery is protected from overdischarge to the greatest extent.

Description

【Technical field】 [0001] The invention relates to the technical field of battery management, in particular to a battery power consumption control method, device and unmanned aerial vehicle. 【Background technique】 [0002] Unmanned aerial vehicle is a product with relatively high safety requirements. As the core of the safety of unmanned aerial vehicles, batteries are particularly important in the safety design of unmanned aerial vehicles. The battery stored for a long time will enter a very low voltage state due to its own power consumption. Once the battery voltage is lower than a threshold (such as 1V), it may cause permanent damage to the battery, thereby causing property loss to the user. . Therefore, we need to adopt some control strategies to reduce the rate of battery self-discharge. [0003] However, in the existing battery power consumption control scheme, generally only some functional modules of the battery are controlled to stop working, while the microprocesso...
