Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Fig. 1 is a schematic flowchart of a first embodiment of a battery control method according to an embodiment of the present invention, and as shown in fig. 1, the battery control method according to the embodiment of the present invention may specifically include the following steps:
101. the state of the battery is detected.
102. And if the state of the battery is in a non-working state, detecting whether the state parameter data of the battery meets a shutdown condition.
The embodiment of the invention provides a battery control method, which judges whether a battery is in a working state by detecting the state of the battery, and detects whether state parameter data of the battery meets a shutdown condition or not if the battery is in a non-working state.
Example two
Fig. 2 is a schematic flowchart of a second embodiment of a battery control method according to an embodiment of the present invention, and as shown in fig. 2, the battery control method according to the embodiment of the present invention may specifically include the following steps:
201. the state of the battery is detected, if the state of the battery is a non-operating state, step 202 is executed, and if the state of the battery is an operating state, step 203 is executed.
In devices that require the use of batteries as an electrical energy supply, such as terminals, electronic devices, drones, etc., it is common that the batteries are installed inside the device, or that the device is connected to the batteries using connection lines so that the electrical energy of the batteries can be delivered into the device.
In order not to affect the operation of the device in which the battery is located, the state of the battery needs to be detected. In an embodiment of the present invention, the state of the battery may include, but is not limited to: an active state and an inactive state.
Since the values of the parameters are different between the operating state and the non-operating state of the battery, for example, a current is generated in the operating state, i.e., the current value is not 0, or no current is generated in the non-operating state, i.e., the current value is 0. Therefore, whether the battery is in the working state can be judged according to the corresponding parameters.
For example, if the current value of the battery is 0, it is determined that the battery is in the non-operating state. For another example, if the current value of the battery is not 0, it is determined that the battery is in the operating state.
202. And detecting whether the state parameter data of the battery meets the shutdown condition.
If the battery is in a non-operating state, the state parameter data of the battery, such as the remaining capacity of the battery, the voltage of the battery, the current of the battery, etc., can be detected, and whether the detected state parameter data satisfies the shutdown condition or not can be determined.
Specifically, if the state parameter data is less than or equal to the preset state parameter threshold, it is detected that the state parameter data of the battery satisfies the shutdown condition, and if the state parameter data is greater than the preset state parameter threshold, it is detected that the state parameter data of the battery does not satisfy the shutdown condition.
For example, the unmanned aerial vehicle is powered by a lithium iron phosphate battery, shutdown is performed when the remaining capacity of the battery is set to be less than or equal to 20% in a non-working state, when the unmanned aerial vehicle does not fly, the remaining capacity of the battery can be detected, and if the remaining capacity of the battery is 19% and 19% is less than 20%, it is detected that the state parameter data of the battery meets shutdown conditions. The shutdown condition is preset in the battery management system.
203. The state of the battery continues to be detected.
And if the state of the battery is in the working state, continuously monitoring the state of the battery in order to not influence the normal use of the equipment where the battery is located.
The embodiment of the invention provides a battery control method, which judges whether a battery is in a working state by detecting the state of the battery, and detects whether state parameter data of the battery meets a shutdown condition or not if the battery is in a non-working state.
EXAMPLE III
Fig. 3 is a schematic flowchart of a third embodiment of a battery control method according to an embodiment of the present invention, and as shown in fig. 3, the battery control method according to the embodiment of the present invention may specifically include the following steps:
301. the state of the battery is detected, and if the state of the battery is not in operation, step 302 is executed, and if the state of the battery is in operation, step 303 is executed.
302. Detecting whether the state parameter data of the battery meets the shutdown condition, if so, executing step 304, and if not, executing step 305.
303. The state of the battery continues to be detected.
304. Shutting down all functions of the battery management system.
Because the battery management system depends on a circuit, the battery management system needs to consume electric energy in the operation process, and the electric energy consumed by the battery management system needs to be reduced in order to ensure that the battery does not have an over-discharge phenomenon, after the condition parameter data of the battery is detected to meet the shutdown condition, various functions of the battery management system need to be processed, and the functions of the management system can comprise a sampling function, a detection function, a processing function and the like. Since the functions of the battery management system required by different devices may be different, all the functions of the battery management system may be turned off in order to reduce the power consumed by the battery management system as much as possible.
For example, a lithium iron phosphate battery is used in an automobile to supply power, shutdown is performed when the voltage of the battery is set to be less than or equal to 100V in a non-working state, the voltage of the battery can be detected when the automobile stops running, if the voltage of the battery is 90V and 90V is less than 100V, it is detected that the state parameter data of the battery meets shutdown conditions, and then all functions of a battery management system are shut down.
305. And continuously detecting whether the state parameter data of the battery meets the shutdown condition.
According to the technical scheme provided by the embodiment of the invention, the battery detects the state parameter data in the non-working state, whether the residual electric quantity of the battery is low can be judged from the state parameter data of the battery, and under the condition that the residual electric quantity of the battery is low, the power consumption of the battery management system is reduced by closing all functions of the battery management system, so that the problem of over-discharge of the battery caused by the depletion of the residual electric quantity of the battery is avoided, the reliability and the safety of the battery are improved, and the service life of the battery is prolonged.
Example four
Fig. 4 is a schematic flowchart of a fourth embodiment of a battery control method according to an embodiment of the present invention, and as shown in fig. 4, the battery control method according to the embodiment of the present invention may specifically include the following steps:
401. the state of the battery is detected, and if the state of the battery is a non-operating state, step 402 is executed, and if the state of the battery is an operating state, step 403 is executed.
402. Detecting whether the state parameter data of the battery meets the shutdown condition, if so, executing step 404, and if not, executing step 405.
403. The state of the battery continues to be detected.
404. Part of the functions of the battery management system are shut down.
Because the battery management system depends on a circuit, the battery management system needs to consume electric energy in the operation process, and the electric energy consumed by the battery management system needs to be reduced in order to ensure that the battery does not have an over-discharge phenomenon, after the condition parameter data of the battery is detected to meet the shutdown condition, various functions of the battery management system need to be processed, and the functions of the battery management system can comprise a sampling function, a detection function, a processing function and the like.
In a specific implementation, a part of the functions to be shut down may be preset in the battery management system. Or, because different functions consume different amounts of electric energy, the battery management system may detect the power consumption of each function, sequence the power consumption of each function from high to low, and turn off a plurality of functions with higher power consumption.
After closing part of the functions, the part of the functions which are not closed can continue to work, so that the battery management system can be ensured to continue to work while the power consumption is reduced.
For example, a lithium iron phosphate battery is used for supplying power to an automobile, shutdown is performed when the voltage of the battery is set to be less than or equal to 100V in a non-working state of the battery, a sampling function in a battery management system is turned off, the voltage of the battery can be detected when the automobile stops running, and shutdown is performed and the sampling function of the battery management system is turned off if the voltage of the battery is 90V and 90V is less than 100V.
405. And continuously detecting whether the state parameter data of the battery meets the shutdown condition.
According to the technical scheme provided by the embodiment of the invention, the battery detects the state parameter data in the non-working state, whether the residual electric quantity of the battery is low can be judged from the state parameter data of the battery, and under the condition that the residual electric quantity of the battery is low, the power consumption of the battery management system is reduced by closing part of functions of the battery management system, so that the problem of over-discharge of the battery caused by the depletion of the residual electric quantity of the battery is avoided, the reliability and the safety of the battery are improved, and the service life of the battery is prolonged.
EXAMPLE five
After step 304 in the third embodiment or after step 404 in the fourth embodiment, the method may further include: and if the battery is detected to start charging, starting the closed function.
Specifically, in the third embodiment of the present invention, after all the functions of the battery management system are turned off in step 304, when it is detected that the battery starts to be charged, the turned-off functions are enabled, and the normal use of the battery management system is resumed. Or in the fourth embodiment, after the partial functions of the battery management system are turned off in step 404, when it is detected that the battery starts to be charged, the turned-off functions are enabled, and the normal use of the battery management system is resumed.
Wherein the battery can be charged using an external power supply.
The battery control method provided by the embodiment of the invention can automatically start the closed function after detecting that the battery starts to charge, thereby realizing the purpose of flexibly controlling the opening or closing of the function in the battery management system by detecting the state parameter data of the battery, and improving the flexibility and the reliability of the use of the battery management system.
EXAMPLE six

Because the battery management system needs to be supported by a circuit, the circuit has certain power consumption, and when the residual electric quantity of the battery is very low, the power consumption of the circuit can exhaust the residual electric quantity of the battery, so that the battery is over-discharged, and the reliability and the safety are poor.
Therefore, embodiments of the present invention provide a battery control method, which can control functions of a battery management system according to a state of a battery, so that power consumption of the battery management system is reduced and reliability and safety of the battery are improved when the remaining power of the battery is low.

Specifically, the state parameter data of the battery may include a remaining capacity of the battery, a current of the battery, a voltage of the battery, and the like.
In the embodiment of the invention, the shutdown condition is preset in the battery management system.
For example, the shutdown condition may be that the voltage of the battery is less than or equal to a voltage threshold, the latter, the remaining capacity of the battery is less than or equal to a remaining capacity threshold, or the current of the battery is less than or equal to a current threshold.
And when the condition that the state parameter data of the battery meets the shutdown condition is detected, closing part of functions of the battery management system. Namely: and when the residual capacity of the battery is detected to be less than or equal to the residual capacity threshold value, closing part of functions of the battery management system, or when the current of the battery is detected to be less than or equal to the current threshold value, closing part of functions of the battery management system, and the like.
The shutdown of some functions may be preset in the battery management system.
In a specific implementation scheme, the power consumption of each function in the battery management system can be detected, and then according to a specified value, a plurality of functions with the largest power consumption, such as a temperature detection function, a current detection function and a voltage detection function, are turned off.
For example, the implementation of part of the function of turning off the battery management system may be: and closing the process for realizing partial functions in the battery management system. Specifically, the battery management system may issue a shutdown instruction to a process corresponding to a part of functions that need to be shut down.
