Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the application. Rather, they are merely examples of apparatus and methods consistent with aspects of the application as detailed in the accompanying claims.
First, the terms involved in the present application will be explained:
embedded controller (Embedded Controller, EC for short): one of the Low Pin Count (LPC) buses suspended from a central processing unit (Central Processing Unit, CPU) is embedded in the main control chip. The embedded controller is mainly used for helping computing devices such as notebook computers to manage low-speed peripherals, such as touch pads, matrix keyboards and the like, and most importantly, the notebook computers do power management through EC.
Aiming at the forced discharge existing in the related technology, the discharge power of many portable devices (such as notebook computers) cannot meet the performance requirement of the system, and the problems of abnormal shutdown or system performance reduction can occur. Based on the problem, the application provides a battery discharging control method, a device and a storage medium, which can ensure that the battery is rapidly discharged to a maintenance mode under the condition of ensuring that the performance of the system is not influenced by the fact that the battery auxiliary power adapter supplies power to the system together by dynamically reducing the output power limit of the power adapter step by step.
Fig. 1 is an illustration of an application field Jing Shi of a method for controlling discharge of a battery according to an embodiment of the present application. As shown in fig. 1, when the battery of the notebook computer is maintained, the battery is set to be in a maintenance mode, that is, the battery enters the maintenance mode, and then, the notebook computer dynamically adjusts the output power of the power adapter according to the electric quantity of the battery, for example, when the electric quantity of the battery is greater than the maintenance electric quantity, the output power of the power adapter is dynamically reduced step by step, so that the auxiliary power adapter of the notebook battery supplies power to the system together, and the battery of the notebook computer can be quickly discharged to the maintenance mode under the condition that the performance of the system is not influenced.
It should be noted that fig. 1 is only an example of an application scenario of the present application, and is not meant to limit the present application, for example, a notebook computer may be replaced by another portable device having a battery and a power adapter.
Next, a discharge control method of the battery will be described in detail with reference to specific embodiments.
Fig. 2 is a flowchart illustrating a method for controlling discharge of a battery according to an embodiment of the application. It will be appreciated that the embodiment of the present application provides a method for controlling discharge of a battery, and the execution body of the method may be an EC or other component with a certain force in the notebook computer in fig. 1, such as a processor, and the EC is illustrated herein. As shown in fig. 2, the discharge control method of the battery includes:
s21, detecting the battery electric quantity of the battery when the battery is detected to be in the maintenance mode.
When the battery of the portable device needs to be serviced, the user turns on/starts the service mode of the battery. Correspondingly, the EC detects whether the battery is in the maintenance mode, and performs an operation of detecting the current battery charge of the battery if it is detected that the battery is in the maintenance mode.
S22, if the battery electric quantity is larger than the maintenance electric quantity, the output power of the power adapter is reduced to be the first power.
Wherein the maintenance power of the battery may be different for different portable devices. For example, the maintenance power of a notebook computer may be 50%. Power adapter for a portable device, the output power of the power adapter may be the energy provided by the power adapter to the portable device per unit time.
It will be appreciated that the output power of the power adapter is initially set. In response to the battery level being greater than the maintenance level, the EC may reduce the output power of the power adapter from the set power to the first power. For example, the set power may be the rated output power of the power adapter.
Optionally, the discharge control method of the battery may further include: in response to the battery charge being equal to the maintenance charge, the EC turns off the charging function; and/or, in response to the battery charge being less than the maintenance charge, the EC turns on the charging function until the battery charge of the battery is equal to the maintenance charge, and turns off the charging function.
S23, detecting whether the discharge current of the battery is within a set range.
After the output power of the power adapter is reduced to be the first power, the EC detects whether the discharge current of the battery in the current state is in a set range in real time.
Alternatively, the boundary value of the set range is set according to the maximum safe discharge current of the battery. The setting ranges corresponding to the different batteries may be different or the same, and thus the setting ranges may be selected according to the batteries. As a possible embodiment, the limit value of the set range does not exceed the maximum safe discharge current of the battery. For a battery with a maintenance charge of 50%, the corresponding setting range may be 0.5C-1C, where C is the capacity of the battery.
Step S24 is performed in response to the discharge current of the battery being within the set range.
And S24, keeping the output power of the power adapter to be the first power, and adjusting the output power of the power adapter to be the set power when the electric quantity of the battery is equal to the maintenance electric quantity, wherein the set power is larger than the first power.
In some embodiments, maintaining the output power of the power adapter at the first power condition may include: the discharge current of the battery is maintained in the set range for a set period of time. That is, the discharge current of the battery is within the set range and is maintained for a set period of time, so that the output power of the power adapter is maintained as the first power. For example, the set duration may be 1 second or other data, and may be specifically set according to actual requirements or historical experience.
And in the process of maintaining the output power of the power adapter, detecting the electric quantity of the battery in real time, and adjusting the output power of the power adapter to be set power when the electric quantity of the battery is equal to the maintenance electric quantity, namely adjusting the output power of the power adapter to be set power after discharging to the maintenance electric quantity so as to avoid the system performance reduction caused by the adjustment of the output power.
According to the embodiment of the application, under the condition that the battery is detected to be in the maintenance mode, the battery electric quantity of the battery is detected, and if the battery electric quantity is larger than the maintenance electric quantity, the output power of the power adapter is reduced to be the first power; and then, detecting whether the discharge current of the battery is in a set range, if so, keeping the output power of the power adapter to be the first power, and adjusting the output power of the power adapter to be the set power when the electric quantity of the battery is equal to the maintenance electric quantity. According to the embodiment of the application, the battery can be rapidly discharged to the maintenance electric quantity under the condition that the system performance is not influenced, for example, the battery can be discharged to the maintenance electric quantity within 1 to 2 hours.
Further, on the basis of the above embodiment, the discharge control method of the battery may further include: in response to the discharge current of the battery not being within the set range, the output power of the power adapter is continuously adjusted. The following is a specific description:
In one implementation, in response to the discharge current of the battery being less than the smaller boundary value of the set range, the output power of the power adapter is reduced step by step until the discharge current of the battery is within the set range after the output power is reduced; and then, maintaining the output power of the power adapter, and adjusting the output power of the power adapter to be set power when the electric quantity of the battery is equal to the maintenance electric quantity.
In some embodiments, the output power of the power adapter is reduced step by step only if the discharge current of the battery is less than a small boundary value of the set range for a long period of time. The time length can be equal to the set time length, can be 1 second or other data, and can also be set according to actual requirements or historical experience.
In another implementation, in response to the discharge current of the battery being greater than the greater boundary value of the set range, restoring the output power of the power adapter to the previous level of power of the current power until the discharge current of the battery is within the set range after restoring the output power; and then, maintaining the output power of the power adapter, and adjusting the output power of the power adapter to be set power when the electric quantity of the battery is equal to the maintenance electric quantity.
In some embodiments, the output power of the power adapter is restored to the previous power of the current power only when the discharge current of the battery is greater than the larger boundary value of the set range for a long period of time. The time length can be equal to the set time length, can be 1 second or other data, and can also be set according to actual requirements or historical experience.
Illustratively, the output power of the power adapter is reduced to 70% in response to the discharge current of the battery being less than the smaller boundary value of the set range for 1 second; then, detecting whether the discharge current of the battery is in a set range; if the discharging current of the battery is in the set range, the output power of the power adapter is kept to be 70%, and when the electric quantity of the battery is equal to the maintenance electric quantity, the output power of the power adapter is adjusted to be the set power; if the discharging current of the battery is not in the set range and is still smaller than the smaller boundary value of the set range, the output power of the power adapter is reduced to 60%, and the cycle is repeated in the same way; if the discharge current of the battery is not within the set range and is larger than the larger boundary value of the set range, the output power of the power adapter is recovered to 80%, and the cycle is repeated in the same way.
Illustratively, referring to FIG. 3, after the notebook computer enters battery service mode, the EC performs the following operations:
S31, detecting whether the electric quantity of the battery is less than or equal to 50 percent.
In this embodiment, the maintenance power of the battery of the notebook computer is set to be 50%, and the EC detects whether the battery power of the battery is less than or equal to 50% of the battery capacity. If the battery power of the battery is less than or equal to 50% of the battery capacity, executing S32; if the battery charge of the battery is greater than 50% of the battery capacity, S33 is performed.
S32, detecting whether the battery power is less than 50%.
The EC detects whether the battery electric quantity of the battery is smaller than 50% of the battery capacity, if the battery electric quantity of the battery is smaller than 50% of the battery capacity, the charging function is maintained until the battery electric quantity is 50%, and charging is stopped; if the battery charge of the battery is equal to 50% of the battery capacity, the charging function is turned off.
S33, the output power of the power adapter is reduced to 80% of rated power.
In the case where the battery charge of the battery is greater than 50% of the battery capacity, the EC reduces the output power of the power adapter from the rated power to 80% of the rated power. It should be understood that the rated power is the set power described above.

That is, the EC detects whether the battery discharge current (i.e., the discharge current of the battery) is between 0.5C and 1C. Wherein, C represents the rated capacity of the battery, and 1C represents the rated discharge current of the battery; when the EC detects whether the battery discharge current is between 0.5C and 1C, the discharge current does not include two discrete values of 0.5C and 1C, and if the EC detects that the battery discharge current is between 0.5C and 1C, S35 is performed; if the EC detects that the battery discharge current is not within the range of 0.5C and 1C, S36 is performed.
S35, it is detected whether the battery power is=50%.
If the battery electric quantity is equal to 50%, recovering the output power of the power adapter, namely recovering the output power of the power adapter to be rated power; if the battery power is not equal to 50%, the battery discharge state is kept.
