Fig. 1 is an exemplary application scenario diagram provided in an embodiment of the present disclosure, which may be suitable for power consumption monitoring of an electronic device. In fig. 1, a battery is mounted in an electronic apparatus, and a battery management system is provided in the electronic apparatus. Here, the battery management system is part of an operating system installed in the electronic device, and, for example, if the android operating system is installed in the electronic device, the battery management system is part of the android operating system. If the IOS operating system is installed in the electronic device, the battery management system is part of the IOS operating system. In some embodiments of the present invention, in some embodiments,
the battery management system may detect status information of the battery in real time, including but not limited to: the remaining capacity of the battery, the average charge/discharge current milliamperes for a period of time, and the current charge/discharge current milliamperes. The battery management system may provide an API interface to the outside for querying battery management information, including but not limited to: the interface is used for inquiring the percentage of the residual electric quantity: BATTERY_PROPERTY_CAPACITY; an interface for querying an average charge/discharge current milliampere for a period of time: BATTERY_PROPERTY_CURRENT_AVERAGE; interface for inquiring present charge/discharge current milliamperes: BATTERY_PROPERTY_CURRENT_NOW.
In fig. 1, the electronic device may further comprise means for determining the average current of the battery, which may be implemented as part of the battery management system or as a separate device from the battery management system. The two dashed boxes in fig. 1 represent two embodiments of the device for determining the average current of the battery. In some embodiments, the means for determining the average current of the battery is implemented in software, hardware, or a combination of software.
The device for determining the average current of the battery can acquire first battery management information of the battery from the battery management system at a first moment and acquire second battery management information of the battery at a second moment through a preconfigured battery management interface, and further can determine the average current of the battery between the first moment and the second moment by utilizing the first battery management information and the second battery management information. Therefore, the device for determining the average current of the battery can accurately acquire the average current of the battery only by acquiring the battery management information twice, and reduces the current sampling times, so that the disturbance to the battery management system is reduced, and the load of the battery management system is not increased.
In some embodiments, the battery management interface is, for example, a battery remaining capacity interface, such as an interface for querying a percentage of remaining power: BATTERY_PROPERTY_CAPACITY.
In some embodiments, the battery management interface is, for example, an average current interface, such as an interface for querying an average charge/discharge current milliamp over a period of time: BATTERY_PROPERTY_CURRENT_AVERAGE.
Fig. 2 is a flowchart of a method for determining average current of a battery according to an embodiment of the present disclosure, where the method may be applicable to a case of monitoring power consumption of an electronic device, where the method may be performed by a device for determining average current of a battery, where the device may be implemented in software and/or hardware, and where the device may be configured in an electronic device, for example, a terminal, and specifically includes, but is not limited to, a smart phone, a palm top computer, a tablet computer, a wearable device with a display screen, a desktop computer, a notebook computer, an all-in-one machine, a smart home device, and so on. Alternatively, the embodiment may be applied to a case where power consumption monitoring is performed in a server, where the method may be performed by a device for determining an average current of a battery, where the device may be implemented in software and/or hardware, and where the device may be configured in an electronic device, such as a server.
Referring to fig. 2, the method of determining the average current of the battery includes:
s110, acquiring first battery management information of a battery at a first moment and acquiring second battery management information of the battery at a second moment.
In some embodiments, first battery management information for a battery may be obtained from a battery management system at a first time and second battery management information for the battery may be obtained from the battery management system at a second time based on a preconfigured battery management interface.
Alternatively, in this step, the battery management interface may be a battery remaining capacity interface and/or an average current interface.
Illustratively, if the battery management interface is a battery remaining capacity interface; the first battery management information is first battery remaining capacity information; the second battery management information is second battery remaining capacity information.
If the battery management interface is an average current interface; the first battery management information includes first average current information and a first time; the second battery management information includes second average current information and a second time.
S120, determining a target average current calculation method according to the attributes of the first battery management information and the second battery management information.
In some embodiments, determining the target average current calculation method as a residual capacity method according to the attribute as the residual capacity; the first battery management information is first battery remaining capacity information; the second battery management information is second battery remaining capacity information.
In some embodiments, the target average current calculation method is determined to be an average current method according to the attribute being an average current; the first battery management information includes first average current information and a first time; the second battery management information includes second average current information and a second time.
S130, determining the average current of the battery between the first moment and the second moment based on the target average current calculation method, the first battery management information and the second battery management information.
The specific implementation method of this step is various, and optionally, an appropriate calculation method may be selected according to the specific content of the first battery management information and the second battery management information, so as to determine the average current of the battery between the first time and the second time.
In some embodiments, the battery management system is part of an operating system in which the electronic device is installed. Whether the scheme is adopted or not, the battery management system can detect the battery state of the electronic equipment in real time in the running process of the electronic equipment. In some embodiments, the detection result of the battery state of the electronic device by the battery management system can be "directly taken" and used to find the average current. So that it does not disturb the system. In the prior art, the API is an external interface, which is an interface used by a programmer in programming, through which a system and an application program can access resources in the system or obtain services of the OS in execution, and is the only way for the program to obtain services of the operating system. It will only output data when called. Acquiring data through an API can be intrusive to the system.
Therefore, the technical scheme can accurately acquire the average current of the battery only by acquiring the battery management information twice, and reduces the current sampling times, so that the disturbance to the battery management system is reduced, and the load of the battery management system is not increased.
Fig. 3 is a flowchart of a method for implementing S130 according to an embodiment of the disclosure. On the basis of the technical scheme, if the target average current calculation method is a residual capacity method; the first battery management information is first battery remaining capacity information; the second battery management information is second battery remaining capacity information, optionally, referring to fig. 3, the method for implementing S130 includes:
s1301, determining a battery capacity loss based on the first battery remaining capacity information and the second battery remaining capacity information.
S1302, determining an average current based on the time interval and the battery capacity loss. The time interval is a preset time interval or a calculated time interval. The calculated time interval is a time interval calculated based on the first time instant and the second time instant.
In some embodiments, the battery capacity satisfies the following formula:
battery capacity per hour (mAh) =average current (mA) ×1h (1)
If the remaining battery capacity information is acquired every a seconds, the first time is A1, and the second time is A2. The first battery remaining capacity information at the first time A1 is B1 (in nanoampere-hour nAh), and the second battery remaining capacity information at the second time A2 is B2 (in nanoampere-hour nAh). It is assumed that the average current during this period is c from the first time A1 to the second time A2.
The first battery remaining capacity information B1 and the second battery remaining capacity information B2 are converted into units of milliampere hours (mAh) by dividing B1 by 1000 and dividing B2 by 1000.
When the time interval a is converted into a unit (h), the conversion method is to divide a by 3600.
The first battery remaining capacity information B1, the second battery remaining capacity information B2, and the time interval a after the unit conversion are taken into formula (1), and the result is obtained:
(B2–B1)/1000＝c×a/(3600) (2)
performing term transfer on the formula (2) to obtain
c＝18×(B1－B2)/(5×a) (3)
Thus, alternatively, the average current is determined by equation (3):
wherein c is average current in milliamperes; B1-B2 are battery capacity loss, B1 is first battery residual capacity information, and B2 is second battery residual capacity information when the unit is nanoamperes, and the unit is nanoamperes; a is a time interval in seconds.
The essence of the technical scheme is that the current value in a period of time is reversely pushed based on the residual capacity of the battery, the average current of the battery can be accurately obtained only by obtaining the battery management information twice, and the current sampling times are reduced, so that the disturbance to the battery management system is reduced, and the load of the battery management system is not increased.
In the above technical solution, if the time interval a is short enough, the average current calculated by the above formula (3) may be directly used as the real-time current value.
Fig. 4 is a flowchart of another method for implementing S130 according to an embodiment of the disclosure. On the basis of the technical scheme, if the target average current calculation method is an average current method; the first battery management information includes first average current information and a first time; the second battery management information includes second average current information and a second time, and optionally, referring to fig. 4, the method of implementing S130 includes:
s1311, determining an average current difference value based on first average current information and second average current information;
s1312 determines an average current of the battery between the first time and the second time based on the first time, the time interval, the second average current information, and the average current difference. The time interval is a calculated time interval or a preset time interval. Wherein the calculated time interval is a time interval calculated based on the first time instant and the second time instant.
In some embodiments, the average current satisfies the following formula:
battery consumption/time=average current (4)
If starting from a certain time x0, the first average current information from x0 to a first time x1 is c1; the first average current information from x0 to the second instant x2 is c. Wherein x0 is earlier than x1, x1 is earlier than x2; and the time interval between the first time x1 and the second time x2 is a, namely
x2＝x1+a。 (5)
Assume that from x0 to a first time x1, the battery consumption amount is y1; from x0 to a second time x2, the battery consumption is y2; the battery consumption is y2-y1 from the first time x1 to the second time x 2.
For the convenience of calculation, let x0 take the electronic device on time, x0=0.
Bringing the above parameters into the above formula (4) yields:
c1＝y1/x1 (6)
c2＝y2/x2 (7)
the average current information c from the first time x1 to the second time x2 is:
c＝(y2-y1)/(x2-x1)＝(y2-y1)/a (8)
solving the equation yields:
c＝(c2－c1)×t1/a+c2。 (9)
thus, optionally, the average current of the battery between the first time and the second time is set to be determined by the above formula (9);
wherein c is the average current between the first time and the second time; c2-c1 is the average current difference, c2 is the second average current information, and c1 is the first average current information; t1 is a first moment; a is the time interval.
The essence of the technical scheme is that the current value in a period of time is reversely deduced based on the total average current value, the average current of the battery can be accurately obtained only by obtaining the battery management information twice, and the current sampling times are reduced, so that the disturbance to the battery management system is reduced, and the load of the battery management system is not increased.
