Detailed Description
The following description is based on illustrated embodiments of the application and should not be taken as limiting the application with respect to other embodiments that are not detailed herein. The term "module" as used herein may be considered a software object executing on the computing system. The various modules, engines, and services herein may be considered as objects of implementation on the computing system.
An execution subject of the battery management method may be the battery management device provided in the embodiment of the present application, or an electronic device integrated with the battery management device. The electronic device includes a battery, and the electronic device may be a smart phone, a tablet computer, a Personal Digital Assistant (PDA), or the like.
The following is a detailed description of the analysis.
Referring to fig. 1, fig. 1 is a first flowchart illustrating a battery management method according to an embodiment of the present application, where the battery management method includes the following steps:
in 101, an ambient temperature is acquired.
In the embodiment of the application, when a battery of the electronic device generates heat, the electronic device detects the temperature of the environment where the electronic device is located through the temperature sensor so as to obtain the detection value of the environment temperature. During the charging process or the using process of the electronic equipment, the battery of the electronic equipment generates heat.
At 102, if the ambient temperature is greater than a preset first temperature threshold, the battery temperature is obtained.
For example, after obtaining the ambient temperature, the electronic device obtains a preset first temperature threshold, compares the ambient temperature with the preset first temperature threshold, obtains the battery temperature if the ambient temperature is greater than the preset first temperature threshold, and does not perform any operation if the ambient temperature is less than or equal to the preset first temperature threshold.
The battery temperature may refer to a temperature at a certain position on the outer surface of the battery, or the battery temperature may refer to an average temperature of a plurality of positions on the outer surface of the battery. For example, the temperature at a certain position on the outer surface of the battery is measured by a thermistor, and the temperature is taken as the battery temperature.
Taking an electronic device including three batteries, C1, C2 and C3 as examples, the temperature of a certain position on the outer surfaces of the batteries C1, C2 and C3 is measured by thermistors and recorded as T1, T2 and T3, and if the difference between each of T1, T2 and T3 is not large, for example, less than or equal to a certain set value (5 degrees celsius), the average value of T1, T2 and T3 is taken as the battery temperature. If the difference between each of T1, T2, and T3 is large, for example, greater than a predetermined value (5 degrees celsius), the maximum temperature among T1, T2, and T3 is taken as the battery temperature.
The preset first temperature threshold is preset in the electronic device, and the numerical value is not particularly limited. For example, the electronic device a reads locally stored data to obtain a preset first temperature threshold of 25 ℃. The preset first temperature threshold may be set autonomously by a user, or may be set by the electronic device according to a certain rule.
For example, the electronic device obtains an average temperature of a position where the electronic device is located, and sets the average temperature to be a preset first temperature threshold, wherein the average temperature may be an average temperature in the day, an average temperature in the month, an average temperature in the season, or the like.
It should be noted that, when the ambient temperature is greater than the preset first temperature threshold, the battery is not favorable to dissipate heat under the ambient condition, so the electronic device needs to acquire the battery temperature, and the discharge amount of the battery is determined according to the ambient temperature and the battery temperature, so as to adjust the discharge amount of the battery. When the ambient temperature is less than or equal to the preset first temperature threshold, the battery is favorable for heat dissipation under the ambient condition, so that the electronic equipment does not need to control the discharge capacity of the battery to help the battery to dissipate heat.
Referring to fig. 2, fig. 2 is a schematic view of a scenario of a battery management method according to an embodiment of the present disclosure. The user respectively plays games in the air-conditioned room and the outdoor by using the same terminal, the ambient temperature in the air-conditioned room is t1, the outdoor ambient temperature is t2, and t1 is less than t 2. Since the terminal generates heat when the user plays a game on the terminal, the battery temperature t3 may be higher than the ambient temperature t1 and the ambient temperature t 2. Taking the user as an example of using the terminal in the air-conditioned room, when the user uses the terminal in the air-conditioned room, the battery temperature t3 and the ambient temperature t1 have a temperature difference, the battery diffuses heat into the environment, and the battery temperature t3 decreases. The lower the ambient temperature, the more the battery is favorable to dissipating heat, and the higher the ambient temperature, the more the battery is unfavorable to dissipating heat. Namely, the heat dissipation capacity of the battery of the electronic equipment in the external environment with lower temperature is higher than that of the battery in the external environment with higher temperature.
In 103, a target discharge amount of the battery is determined according to the ambient temperature and the battery temperature.
For example, after acquiring the battery temperature, the electronic device determines a target discharge amount of the battery according to the ambient temperature and the battery temperature. The target discharge capacity is the current maximum discharge value of the battery on the premise that the electronic equipment prevents the temperature of the battery from being too high. If the current discharge amount of the battery exceeds the target discharge amount, the accumulated heat of the battery is excessive, the temperature of the battery is too high, and the electronic equipment is exploded and other dangerous accidents can be caused.
At 104, if the current discharge amount of the battery is greater than the target discharge amount, the current discharge amount is adjusted until the current discharge amount is equal to or less than the target discharge amount.
For example, after determining the target discharge amount of the battery, the electronic device obtains the current discharge amount of the battery, and compares the current discharge amount with the target discharge amount. If the current discharge capacity is larger than the target discharge capacity and the hidden trouble of overhigh battery temperature exists, the electronic equipment needs to adjust the current discharge capacity until the current discharge capacity is equal to or smaller than the target discharge capacity and stops adjusting the current discharge capacity. If the current discharge amount is equal to or less than the target discharge amount, the hidden danger of the battery temperature being too high does not exist basically, and the electronic equipment does not need to execute any operation to adjust the battery temperature.
Therefore, under the condition that the environmental temperature of the electronic equipment is greater than the first preset temperature threshold value, namely under the environmental condition that the battery is not beneficial to heat dissipation, the target discharge capacity of the battery can be determined according to the environmental temperature and the battery temperature, then the discharge capacity of the battery is adjusted to enable the discharge capacity of the battery to be equal to or less than the target discharge capacity, the temperature control of the battery is achieved through the control of the discharge capacity of the battery, and the safety of the electronic equipment is improved.
Referring to fig. 3, fig. 3 is a second schematic flow chart of a battery management method according to an embodiment of the present application, where the flow chart may include:
in 201, an ambient temperature is acquired.
For example, when a battery of an electronic device generates heat, the electronic device detects the temperature of the environment in which the electronic device is located through a temperature sensor to obtain a detected value of the environment temperature. During the charging process or the using process of the electronic equipment, the battery of the electronic equipment generates heat.
At 202, if the ambient temperature is greater than a preset first temperature threshold, the battery temperature is obtained.
For example, after obtaining the ambient temperature, the electronic device obtains a preset first temperature threshold, compares the ambient temperature with the preset first temperature threshold, obtains the battery temperature if the ambient temperature is greater than the preset first temperature threshold, and does not perform any operation if the ambient temperature is less than or equal to the preset first temperature threshold.
In 203, it is detected whether the battery temperature is less than a preset second temperature threshold.
For example, after the ambient temperature of the environment where the electronic device is located is obtained, the electronic device detects that the ambient temperature is greater than a preset first temperature threshold, and at this time, the electronic device may obtain the battery temperature. After the battery temperature is obtained, the electronic equipment obtains a preset second temperature threshold value, and detects whether the battery temperature is smaller than the preset second temperature threshold value.
The preset second temperature threshold is preset in the electronic device, and the value is not specifically limited, such as 55 degrees celsius, 58 degrees celsius, and the like. For example, the electronic device B reads the locally stored data to obtain that the preset second temperature threshold is 60 degrees celsius. The preset second temperature threshold may be set by a user, or may be set by the electronic device according to a certain rule. It should be noted that the preset second temperature threshold may be greater than or equal to the preset first temperature threshold.
In 204, if it is detected that the battery temperature is less than the preset second temperature threshold, a temperature difference between the ambient temperature and the battery temperature is obtained.
For example, after detecting whether the battery temperature is less than the preset second temperature threshold, if the battery temperature is less than the preset second temperature threshold, the electronic device obtains a temperature difference between the ambient temperature and the battery temperature. If the battery temperature is greater than or equal to the preset second temperature threshold, the electronic equipment directly adjusts the operation mode into the standby mode.
For another example, after detecting whether the battery temperature is less than the preset second temperature threshold, if the battery temperature is less than the preset second temperature threshold, the electronic device may obtain a temperature ratio between the ambient temperature and the battery temperature.
In 205, a target discharge amount matching the temperature difference is determined, wherein the absolute value of the temperature difference is proportional to the target discharge amount.
For example, after acquiring a temperature difference between the ambient temperature and the battery temperature, the electronic device determines a target discharge amount that matches the temperature difference. The larger the absolute value of the temperature difference is, the more the battery heat dissipation is facilitated, so the target discharge capacity is larger; the smaller the absolute value of the temperature difference, the more adverse the battery heat dissipation at this time, so the smaller the target discharge amount, i.e., the absolute value of the temperature difference is proportional to the target discharge amount.
For example, a mapping relationship between a preset temperature difference and a target discharge amount is set in advance in the electronic device. The target discharge amount corresponding to each preset temperature difference in the plurality of preset temperature differences can be set in a manual setting mode. And then, establishing a preset mapping relation between the preset temperature difference and the target discharge amount according to the plurality of preset temperature differences and the target discharge amount corresponding to each preset temperature difference.
For another example, the electronic device obtains a temperature ratio between the ambient temperature and the battery temperature, and determines a target discharge amount matching the temperature ratio. The larger the absolute value of the difference between the temperature ratio and 1 is, the more the battery heat dissipation is facilitated, so the target discharge capacity is larger; the smaller the absolute value of the difference between the temperature ratio and 1, the more adverse the battery heat dissipation, so the smaller the target discharge amount, i.e. the absolute value of the difference between the temperature ratio and 1 is proportional to the target discharge amount.
For example, a mapping relationship between a preset temperature ratio and a target discharge amount is set in advance in the electronic device. The target discharge amount corresponding to each preset temperature difference in the preset temperature ratios can be set in a manual setting mode. And then, establishing a preset mapping relation between the preset temperature ratio and the target discharge amount according to the plurality of preset temperature ratios and the target discharge amount corresponding to each preset temperature ratio.
It should be noted that, when the difference between the ambient temperature and the battery temperature is-P and P, the target discharge amount determined by the electronic device is the same.
At 206, the background application is determined if the current discharge amount of the battery is greater than the target discharge amount.
For example, after determining the target discharge amount of the battery, the electronic device obtains the current discharge amount of the battery, and compares the current discharge amount with the target discharge amount. If the current discharge capacity is larger than the target discharge capacity and the hidden trouble of overhigh battery temperature exists at the moment, the electronic equipment determines the background application program and adjusts the battery temperature by closing part or all of the background application programs. If the current discharge amount is equal to or less than the target discharge amount, the hidden danger of the battery temperature being too high does not exist basically, and the electronic equipment does not need to execute any operation to adjust the battery temperature.
At 207, the priority of the background application is determined.
For example, after determining the background applications, the electronic device determines the priority of each background application according to the importance of the background application. The more important the background application is relative to the user, the higher the priority of the application; and vice versa.
In one embodiment, the electronic device may acquire running information of the background application program in a historical time period, wherein the running information includes a running time length and a use frequency; and determining the priority of the background application program according to the running information. For example, the longer the running time and the higher the use frequency of the background application program are, the higher the priority of the background application program is; the shorter the running time and the lower the use frequency of the background application program are, the lower the priority of the background application program is.
In 208, the background applications are closed one by one according to the priority until the current discharge amount is equal to or less than the target discharge amount.
For example, after the priority of the background application program is determined, the electronic device closes the background application program one by one according to the priority from low to high until the current discharge amount is equal to or less than the target discharge amount, and then stops closing the background application program.
For example, electronic device C determines that the background applications are: the application program Y1, the application program Y2, the application program Y3, the application program Y4 and the application program Y5, and the priority of the application programs is as follows: application Y1< application Y2< application Y3< application Y4< application Y5. The electronic equipment closes the application programs running in the background one by one from top to bottom according to the priority, acquires the current discharge capacity of the battery after closing the background application program every time the background application program is closed, compares the current discharge capacity with the target discharge capacity, and stops closing the background application program if the current discharge capacity is equal to or less than the target discharge capacity.
For another example, before closing the background applications one by one according to the priority, the electronic device may output a prompt message on the display interface, where the prompt message is used to initiate a request for closing the background applications to the user; and when a background application program closing instruction triggered based on the prompt information is detected, executing the closing of the application programs one by one according to the priority. According to the scheme, the request for closing the background application program is firstly sent to the user before the background application programs are closed one by one according to the priority, so that the user experience can be improved.
In one embodiment, after the electronic device performs steps 206, 207, and 208, all applications running in the background are already closed, but the current discharge amount is still greater than the target discharge amount, the display brightness of the display screen of the electronic device is gradually decreased with the preset brightness as each adjustment amount until the current discharge amount is equal to or less than the target discharge amount.
Referring to fig. 4, fig. 4 is a schematic diagram of a third process of a battery management method according to an embodiment of the present application, where the process may include:
in 301, an ambient temperature is acquired.
For example, when a battery of an electronic device generates heat, the electronic device detects the temperature of the environment in which the electronic device is located through a temperature sensor to obtain a detected value of the environment temperature. During the charging process or the using process of the electronic equipment, the battery of the electronic equipment generates heat.
At 302, if the ambient temperature is greater than a preset first temperature threshold, the battery temperature is obtained.
For example, after obtaining the ambient temperature, the electronic device obtains a preset first temperature threshold, compares the ambient temperature with the preset first temperature threshold, obtains the battery temperature if the ambient temperature is greater than the preset first temperature threshold, and does not perform any operation if the ambient temperature is less than or equal to the preset first temperature threshold.
In 303, it is detected whether the battery temperature is less than a preset second temperature threshold.
For example, after the ambient temperature of the environment where the electronic device is located is obtained, the electronic device detects that the ambient temperature is greater than a preset first temperature threshold, and at this time, the electronic device may obtain the battery temperature. After the battery temperature is obtained, the electronic equipment obtains a preset second temperature threshold value, and detects whether the battery temperature is smaller than the preset second temperature threshold value.
At 304, if the battery temperature is detected to be greater than or equal to the preset second temperature threshold, the operation mode is adjusted to the standby mode.
For example, after detecting whether the battery temperature is less than the preset first temperature threshold, if the battery temperature is greater than or equal to the preset first temperature threshold, the battery temperature is already high, and even if the battery temperature is put into an environment favorable for heat dissipation, the battery temperature cannot be reduced in a short time. The electronic device can directly adjust the operation mode to the standby mode. When the electronic device adjusts the operation mode to the standby mode, the operation data is stored in the memory, and the battery only needs to supply power to the memory and does not need to supply power to components such as a hard disk, a screen, a CPU and the like. Therefore, the discharge amount of the battery in the standby mode is small, and the generation of heat from the battery can be reduced.
For another example, after detecting whether the battery temperature is less than the preset first temperature threshold, if the battery temperature is greater than or equal to the preset first temperature threshold, the electronic device may obtain a variation trend of the battery temperature, and if the variation trend is an increasing trend, adjust the operation mode to the standby mode; if the change trend is a descending trend, all background programs of the electronic equipment are closed and/or the display brightness of the display screen of the electronic equipment is adjusted to the lowest display brightness.
In one embodiment, after detecting whether the battery temperature is less than a preset first temperature threshold, if the battery temperature is greater than or equal to the preset first temperature threshold, the electronic device displays a prompt message on the display interface, where the prompt message is used to remind a user to enter a standby mode due to an excessively high battery temperature, and then adjusts the operating mode to the standby mode.
In 305, if the battery temperature is detected to be less than the preset second temperature threshold, a temperature difference between the ambient temperature and the battery temperature is obtained.
For example, after detecting whether the battery temperature is less than the preset second temperature threshold, if the battery temperature is less than the preset second temperature threshold, the electronic device obtains a temperature difference between the ambient temperature and the battery temperature.
At 306, a target discharge amount matching the temperature difference is determined, wherein the absolute value of the temperature difference is proportional to the target discharge amount.
For example, after acquiring a temperature difference between the ambient temperature and the battery temperature, the electronic device determines a target discharge amount that matches the temperature difference. The larger the absolute value of the temperature difference is, the more the battery heat dissipation is facilitated, so the target discharge capacity is larger; the smaller the absolute value of the temperature difference, the more adverse the battery heat dissipation at this time, so the smaller the target discharge amount, i.e., the absolute value of the temperature difference is proportional to the target discharge amount.
In 307, if the current discharge amount of the battery is greater than the target discharge amount, the preset brightness is used as each adjustment amount, and the display brightness of the display screen of the electronic device is gradually reduced until the current discharge amount is equal to or less than the target discharge amount.
For example, after determining the target discharge amount, the electronic device obtains the current discharge amount of the battery, and compares the current discharge amount with the target discharge amount. If the current discharge capacity is larger than the target discharge capacity and the hidden trouble that the battery temperature is too high exists at the moment, the electronic equipment gradually reduces the display brightness of the display screen of the electronic equipment by taking the preset brightness as the adjustment quantity each time until the current discharge capacity is equal to or smaller than the target discharge capacity, and the battery temperature is adjusted by reducing the display brightness. If the current discharge amount is equal to or less than the target discharge amount, the hidden danger of the battery temperature being too high does not exist basically, and the electronic equipment does not need to execute any operation to adjust the battery temperature.
The preset brightness can be set by a user independently or can be set by the electronic equipment according to a certain rule. For example, the electronic device determines the preset brightness according to the temperature difference between the ambient temperature and the battery temperature, and the larger the temperature difference is, the larger the preset brightness is, and the smaller the temperature difference is, the smaller the preset brightness is.
In one embodiment, if the display brightness has decreased to the minimum display brightness and the current discharge amount is still greater than the target discharge amount, the battery temperature is adjusted by turning off some or all of the background applications.
