Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, specific technical solutions of the present application will be described in further detail below with reference to the accompanying drawings in the embodiments of the present application. The following examples are intended to illustrate the present application but are not intended to limit the scope of the present application.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the application.
In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is understood that "some embodiments" may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict.
It should be noted that the terms "first \ second \ third" referred to in the embodiments of the present application merely distinguish similar or different objects and do not represent a specific ordering with respect to the objects, and it should be understood that "first \ second \ third" may be interchanged under certain ordering or sequence circumstances to enable the embodiments of the present application described herein to be implemented in other orders than illustrated or described herein.
The embodiment of the application provides a charging method of a terminal battery, which can be applied to electronic equipment, wherein the electronic equipment can be an intelligent mobile terminal (such as a mobile phone, a tablet personal computer and the like), an electronic book, an electronic cigarette, intelligent electronic equipment (such as a watch, a bracelet, intelligent glasses, a sweeping robot and the like), a small electronic product (such as a wireless earphone, a Bluetooth sound box, an electric toothbrush, a rechargeable wireless mouse and the like), or a notebook computer and the like with a battery. The electronic device may also be a power adapter. The functions implemented by the charging method for the terminal battery can be implemented by calling program codes through a processor in the electronic device, and the program codes can be stored in a computer storage medium.
Fig. 1 is a schematic flow chart of an implementation process of a charging method for a terminal battery according to an embodiment of the present application, and as shown in fig. 1, the method may include the following steps 101 to 103:
It will be appreciated that the magnitude of the power consumption level directly reflects the operational state of the terminal. For example, the more or larger foreground and background applications the terminal runs, the higher the power consumption level.
It should be noted that the current temperature of the terminal may be the temperature of the terminal, or may be the temperature of the battery. The electrical parameter value of the battery may be various, for example, the battery level, and the charging voltage of the battery. It is understood that when the charging voltage of the battery exceeds a certain threshold, the battery is in a high voltage state at this time. If the battery is in a high temperature environment, the aging rate of the battery is increased. Therefore, in the embodiment of the present application, the temperature of the terminal is taken into consideration, and the charging voltage of the battery is also taken into consideration, so that the ambient temperature of the battery in a high-voltage state is not too high as much as possible, and the influence of the high voltage and the high temperature on the service life of the battery is reduced.
In implementation, the electronic device may be the terminal, or may be another device. For example, the electronic device is a power adapter that charges the terminal. The electronic equipment can periodically determine the current attribute value of the parameter so as to realize the real-time adjustment of the charging power of the battery; the electronic device may further determine a new current attribute value of the parameter again when it is monitored that the current attribute value of the parameter exceeds the corresponding specific threshold value, so as to implement readjustment of the charging power of the battery.
And step 102, determining a charging adjustment strategy corresponding to the current attribute value of the parameter according to the determined current attribute value of the parameter.
In some embodiments, the electronic device may determine a corresponding charging adjustment policy according to the current power consumption level; the electronic equipment can determine a corresponding charging adjustment strategy according to the current temperature; the electronic device may determine a corresponding charging adjustment strategy based on a current electrical parameter value of the battery. The charging adjustment policy is generally used to indicate whether the electronic device is to continue charging, and if so, the policy indicates how much the electronic device needs to adjust the charging power of the battery up or down, that is, the policy indicates the charging power to be decreased or increased.
For example, when any of the charge adjustment strategies indicates that charging is to be terminated, charging is terminated, charging safety is ensured, and damage to the battery is reduced. For another example, in steps 306 to 308 of the following embodiments, the charging power adjustment values indicated by each charging adjustment strategy are accumulated to obtain an accumulated value; determining a target charging power according to the charging power and the accumulated value of the battery; adjusting the charging power of the battery to a target charging power; in this way, by considering a plurality of influencing factors, the charging power is adjusted, the service life of the battery can be prolonged as much as possible, and the use experience of the user can be maintained.
In the embodiment of the application, when a battery of a terminal is in a charging state, an electronic device determines current attribute values of at least two parameters of the terminal: power consumption level, temperature, electrical parameter values of the battery; determining a charging adjustment strategy corresponding to the current attribute value of the parameter according to the determined current attribute value of the parameter; adjusting the charging power of the battery according to each charging adjustment strategy; therefore, each current attribute value of each parameter has a corresponding charging adjustment strategy, and each charging adjustment strategy is integrated to realize the adjustment of the charging power of the battery, so that the service life of the battery can be prolonged as much as possible, and the use experience of a user is maintained.
The charging method of the terminal battery provided by the embodiment of the present application is described below by taking, as an example, the determined current attribute values of the parameters include a current power consumption level, a current temperature, and a current electrical parameter value of the battery. Of course, in other embodiments, the determined current attribute value of the parameter may also include any two of the above three current attribute values of the parameter, and accordingly, the charging method of the terminal battery is similar to the charging method of the terminal battery provided in the following embodiments, but only one current attribute value of the parameter is reduced, that is, one charging adjustment strategy is reduced.
An embodiment of the present application provides a method for charging a battery of another terminal, and fig. 2 is a schematic flow chart illustrating an implementation of the method for charging a battery of another terminal according to the embodiment of the present application, and as shown in fig. 2, the method may include the following steps 201 to 208:
In some embodiments, the power consumption levels in the set of power consumption levels may be determined from at least one of the following attribute values of the terminal: the number of foreground applications and background applications, screen brightness, uplink and downlink data transmission speed and CPU occupancy rate.
For periodically determining the current attribute value of the parameter, the total number of power consumption levels in the power consumption level set is constant, that is, the number in the power consumption level set acquired each time is constant, so the specific condition may be that the total number is greater than a specific threshold. For example, if the power consumption level set includes 5 values, where the number of power consumption levels 1 is 4, the number of power consumption levels 2 is 1, and the specific threshold is 3, the power consumption level 1 is determined as the current power consumption level.
The total number of power consumption levels in the set of power consumption levels has variability for non-periodically determining the current property value of the parameter, so the particular condition may be a maximum number. For example, the power consumption level set includes 6 values, where the number of power consumption levels 1 is 3, the number of power consumption levels 2 is 1, and the number of power consumption levels 3 is 2, and since the number of power consumption levels 1 is the largest, the power consumption level 1 may be determined as the current power consumption level.
Of course, the specific condition may be a maximum number or greater than a specific threshold value, regardless of whether the parameter current property value is determined periodically or non-periodically.
it will be appreciated that the determination of the current power consumption level is achieved by steps 202 to 205 in order to make the results more reliable. Of course, in some embodiments, the electronic device may directly take the power consumption level at the current time as the current power consumption level.
It should be noted that the execution order of step 206 and step 201 is not limited. In other words, there is no limitation in the order of determining the temperature of the terminal, the electrical parameter value of the battery, and the current power consumption level. The electronic device can determine the current attribute values of the three parameters in parallel, and can also determine the current attribute values in any order.
and 208, adjusting the charging power of the battery according to each charging adjustment strategy.
In the embodiment of the present application, a method for determining a current power consumption level is provided, that is, a set of power consumption levels determined in a preset time period is obtained; determining the number of the same power consumption level in the power consumption level set; determining the power consumption grade corresponding to the number meeting the specific condition as the current power consumption grade; determining the power consumption level determined at the previous moment as the current power consumption level under the condition that each number does not meet the specific condition; therefore, the obtained current power consumption level is more accurate and reliable, and the situation that the charging speed is reduced or the charging risk is increased due to the fact that an unreasonable charging adjustment strategy is adopted for the unreliable current power consumption level is avoided.
Fig. 3 is a schematic flow chart illustrating an implementation of a charging method for a terminal battery according to another embodiment of the present application, and as shown in fig. 3, the method may include the following steps 301 to 308:
Here, it should be noted that the first threshold values corresponding to the current attribute values of the different types of parameters are different.
It can be understood that, in the case that the current attribute value of any parameter is greater than or equal to the corresponding first threshold value, if the battery is still charged, the battery may be damaged greatly, and even the risk of explosion of the battery may be increased, which may endanger the life safety of the user. Therefore, in this case, it is necessary to terminate the battery charging, and only the terminal is powered at this time, so as to meet the user demand for the terminal.
In other words, when the charging adjustment strategy corresponding to the current attribute value of any parameter is to terminate charging, the charging power of the battery is adjusted to terminate charging the battery. Of course, if the current attribute value of each parameter is smaller than the corresponding first threshold value, the battery continues to be charged.
In some embodiments, for a case that a current attribute value of a parameter is a current power consumption level or a current temperature, the electronic device may obtain a parameter attribute value determined at a historical time that is a certain length of time from a current time; and determining a charging power adjustment value according to the relation between the current attribute value of the parameter and the attribute value of the parameter determined at the historical moment. The historical time may be a time immediately before the current time, or may be N times before the current time, where N is an integer greater than 1.
It can be understood that, when the current attribute value of the parameter is greater than the attribute value of the parameter determined at the historical moment, the determined charging power adjustment value is a value to be reduced; otherwise, the determined charging power adjustment value is to be added. Therefore, by flexibly adjusting the charging power of the battery, on one hand, the service life of the battery is prolonged by reducing the charging power; on the other hand, after the charging power is reduced, if the current attribute value of the parameter is smaller than the attribute value of the parameter determined at the historical moment, the charging power of the battery is increased, and thus the charging speed can be improved.
In practice, the electronic device may determine the charging power adjustment value through steps 404 to 408 of the following embodiments.
And step 306, accumulating the charging power adjustment values corresponding to the current attribute values of each parameter to obtain an accumulated value.
It is understood that the charging power adjustment value may be a charging power decrease waiting value or a charging power increase waiting value. The value to be decreased can be characterized by a negative value or 0 and the value to be increased can be characterized by a positive value or 0. When the method is implemented, the accumulation mode can be direct addition or weighted average. And during weighted averaging, the weight of each charging power adjusting value is related to the size of the corresponding parameter current attribute value, and the larger the parameter current attribute value is, the larger the corresponding weight is.
For example, if the charging power adjustment value corresponding to the current power consumption level is-1 Watt (Watt, W), the charging power adjustment value corresponding to the current temperature is-1W, and the charging power adjustment value corresponding to the battery power of the battery is 0W, each charging power adjustment value is accumulated, and the accumulated value is-2W.
And 307, determining target charging power according to the charging power of the battery and the accumulated value.
When implemented, the target charging power is the sum of the charging power of the battery and the accumulated value. For example, the current charging power of the battery is 10W, the accumulated value is-2W, and the target charging power is 8W.
And 308, adjusting the charging power of the battery to the target charging power.
In the embodiment of the application, under the condition that the current attribute value of any parameter is greater than or equal to the corresponding first threshold value, the battery is stopped to be charged, so that the damage to the battery is reduced, and the charging safety is improved; under the condition that the current attribute value of each parameter is smaller than the corresponding first threshold value, determining a charging power adjusting value corresponding to the current attribute value of each parameter; accumulating each charging power adjustment value to realize the adjustment of the charging power of the battery; therefore, the service life of the battery can be prolonged as far as possible on the premise of ensuring the normal use of the terminal, and the use experience of the user on the terminal is ensured.
Fig. 4 is a schematic flow chart illustrating an implementation of another method for charging a terminal battery according to an embodiment of the present application, and as shown in fig. 4, the method may include the following steps 401 to 411:
In step 403, the battery charging is terminated.
It can be understood that, in the case that the current attribute value of any of the parameters is greater than or equal to the corresponding first threshold, it indicates that if the battery is still being charged, the battery may be damaged greatly, and even the risk of explosion of the battery may be increased, which may endanger the life safety of the user. Therefore, in this case, the charging adjustment strategy corresponding to the current attribute value of the parameter is determined as terminating charging; correspondingly, under the condition that the charging adjustment strategy corresponding to any one of the current attribute values of the parameters is to terminate charging, the charging of the battery is terminated.
It should be noted that the electronic device may also perform step 405 to step 408, then perform step 404, and then enter step 409. Of course, the electronic device may also determine the charging power adjustment values corresponding to the current attribute values of the three parameters in parallel.
the historical time may be a time before the current time, or may be N times before the current time, where N is an integer greater than 1.
Taking the current power consumption level as an example, in some embodiments, when the current power consumption level is greater than the power consumption level at the previous time, the electronic device may obtain a mapping relationship between each specific power consumption level and the candidate value to be reduced, and then determine the specific power consumption level equal to the current power consumption level, so as to use the candidate value to be reduced corresponding to the specific power consumption level as the charging power value to be reduced corresponding to the current power consumption level. The mapping relationship, for example, as shown in table 1, the specific power consumption levels include a first level, a second level, and a third level. And when the current power consumption level is the second level, taking-2W as the corresponding charging power value to be reduced.
TABLE 1
| Specific power consumption level | Candidate waiting value (negative value) |
| First class | 0W |
| Second level | -2W |
| Third level | -3W |
Taking the current temperature as an example, in some embodiments, when the current temperature is greater than the temperature at the previous time, the electronic device may obtain a mapping relationship between each specific temperature range and the candidate value to be decreased, and then determine the temperature range to which the current temperature belongs, so as to use the candidate value to be decreased corresponding to the temperature range as the charging power value to be decreased corresponding to the current temperature.
Here, the method of determining the charging power value to be decreased in step 407 is similar, except that the charging power value to be increased determined here is a positive value or 0.
It should be noted that, steps 405 to 408 provide a method for determining the charging adjustment strategy corresponding to the current temperature and the current power consumption level, respectively. In other words, the method of adjusting the charging strategy provided in steps 405 to 408 is applicable to both the current temperature and the current power consumption level. Only the corresponding charging power value to be increased and value to be decreased are determined, and the reference mapping relations are different.
In the embodiment of the application, the charging power of the battery is flexibly adjusted according to the relation between the current attribute value of the parameter and the attribute value of the parameter determined at the historical moment, and when the current attribute value of the parameter is larger than the attribute value of the parameter determined at the historical moment, the charging power of the battery is reduced; otherwise, the charging power of the battery is adjusted to be larger; therefore, on the premise of prolonging the service life of the battery as far as possible, the charging speed of the battery is improved, and the charging experience of a user is further improved.
In the charging mode, it is generally considered that the terminal is rapidly charged when the terminal is still, i.e. not in use, and the charging speed is greatly reduced when the terminal is in use, for example, the charging power is reduced to 10W. The charging power is reduced in the use process of the terminal because the terminal can generate heat when in use, and meanwhile, the terminal has more and more powerful functions at present, for example, when a large-scale game is operated, a control system can perform a large amount of high-speed calculation to generate a large amount of heat, and part of the heat is transmitted to a battery.
Because the service life of the battery can be influenced when the battery is in a high-temperature environment for a long time, and the battery also has a certain working temperature range, the charging speed of the battery can be reduced when the temperature of the battery is increased to a certain value. However, this is to directly decrease the charging speed in consideration of only the detected surface temperature of the battery. In this way, the charging experience of the user may be affected.
Based on this, an exemplary application of the embodiment of the present application in a practical application scenario will be described below.
On the premise of ensuring normal use of the terminal, the use experience of a user is ensured as much as possible, and the embodiment of the application provides a charging method of a terminal battery, wherein the charging method of the terminal battery is based on a charging mode determined under the comprehensive condition of terminal use (namely power consumption level), current temperature and battery electric quantity.
An embodiment of the present application further provides a method for charging a terminal battery, fig. 5 is a schematic flowchart illustrating an implementation process of another method for charging a terminal battery according to an embodiment of the present application, and as shown in fig. 5, the method may include the following steps 501 to 504:
and step 504, after the first adjustment, performing a second adjustment on the current charging power of the battery according to a charging adjustment strategy corresponding to the current temperature.
In some embodiments, the method further comprises: after the second adjustment, a third adjustment is made to the current charging power of the battery.
It should be noted that, the adjustment of the primary charging power may adjust the current charging power of the battery down or up, or may maintain the current charging power of the battery.
In one example, as shown in fig. 6A, the following steps 601 to 602 may be included:
After the operation level of the terminal is judged, two adjustment modes can be provided, wherein one mode is that the operation level is determined and then is adjusted immediately; and secondly, after the operation level is determined, adjusting for a period of time, for example, the operation level of the terminal is the second level, adjusting the charging power to the charging power corresponding to the second level after the operation level lasts for time t, and if the operation level does not last for the time t, maintaining the current charging power and continuing to charge.
In the embodiment of the application, the charging modes of different strategies are applied by judging the operation level of the terminal and the temperature of the terminal, so that the charging speed is adjusted, the mobile terminal is always in a proper operation environment, the service life of the battery can be prolonged within the normal design use range of the battery, and the use experience of a user is maintained.
In the scheme, the charging strategy is adjusted by taking the temperature and the operation level of the terminal into consideration. In another example, the charging strategy may be further optimized, that is, in step 603 shown in fig. 6B, when it is determined that the terminal charging speed needs to be adjusted, the charge condition of the battery is read, and if the charge condition of the battery is in a relatively high interval, since the aging of the battery is accelerated if the battery is in a high temperature range under high voltage, the charging power is further reduced by one step under high voltage. That is, after the judgment in step 601 and step 602 is finished, and the results of the two steps are superimposed, it is determined that the charging power of the battery is adjusted to be the second charging power, and based on this, in step 503, the battery is continuously read to have an electric quantity of 80%, and at this time, the battery is in a high voltage state, and then the charging power is continuously adjusted to be the third charging power.
The advantage of this is that the battery can be kept from high ambient temperature under high voltage, and the effect of high voltage and high temperature on the service life of the battery is reduced.
It should be noted that the adjusted charging strategy shown in fig. 6A and 6B does not affect the originally designed charging strategy, where the determined multiple charging adjustment strategies are in a superimposed manner, that is, the multiple charging adjustment strategies are in a relationship with each other.
Based on the foregoing embodiments, the present application provides a charging apparatus, which includes modules and units included in the modules, and can be implemented by a processor in an electronic device; of course, the implementation can also be realized through a specific logic circuit; in implementation, the processor may be a Central Processing Unit (CPU), a Microprocessor (MPU), a Digital Signal Processor (DSP), a Field Programmable Gate Array (FPGA), or the like.
