Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present application.
The embodiment of the application provides a charging control method, which can be applied to a mobile terminal. The mobile terminal can be a smart phone, a tablet computer, a desktop computer, a smart watch and other devices.
Referring to fig. 1, fig. 1 is a first flowchart of a charging control method according to an embodiment of the present disclosure. The charging control method is applied to a mobile terminal, and can comprise the following steps:
And 104, when the second electric quantity is accumulated to a preset storage upper limit value, instantly outputting the second electric quantity to the battery so as to enable the first electric quantity and the second electric quantity to be accumulated to form battery electric quantity.
Specifically, when the mobile terminal is charged, the battery is normally charged, the electric quantity is stored virtually, and when the second electric quantity stored virtually is accumulated to the preset storage upper limit value, the second electric quantity reaching the preset storage upper limit value is output to the battery terminal instantly, so that the battery is charged quickly. In the charging process of the mobile terminal, the second electric quantity virtually stored is accumulated to a preset storage upper limit value for a plurality of times, in the charging process, the accumulated second electric quantity is output to a battery end in a segmented and rapid mode, so that the battery is charged fully, the second electric quantity virtually stored accumulates 1 time to the preset storage upper limit value every time the second electric quantity virtually stored is output to the battery end every preset time T, at the preset time T, the second charging current of the battery is normal, when the second electric quantity virtually stored reaches the preset storage upper limit value and is output to the battery end instantly, the instant charging current is the first charging current of the preset time T and the second charging current of the virtually stored electric quantity to be charged together, the mobile terminal does not need to output large current for charging continuously for a long time, the battery can be charged rapidly at the same time, the mobile terminal is greatly protected from being damaged by the large current charging, and user experience is improved.
Referring to fig. 2, fig. 2 is a second flowchart of a charging control method according to an embodiment of the present disclosure. The charging control method is applied to a mobile terminal, and can comprise the following steps:
For example, when the mobile terminal is charged, the adapter continuously outputs a large current to the mobile terminal for charging. For example, when the total charging current I of the mobile terminal is greater than 3A, the charging is performed with a large current. When the total charging current I output to the mobile terminal by the adapter is larger than 3A, the battery is controlled to be normally charged in order to protect the battery, at the moment, the electric quantity virtual storage module is required to be started to virtually store partial electric quantity, the charging electric quantity is dynamically and virtually stored in the electric quantity virtual storage module stage, and the mobile terminal can control large current to be continuously charged for a long time through the electric quantity virtual storage module. The electric quantity virtual storage module is used for storing energy instantly.
For example, when the battery is normally charged, the first charging current I1<2A, and the first charging current I1 is used for charging the battery to generate the first electric quantity V1.
For example, the second charging current I2>1A, and the charge virtual storage module simultaneously virtually stores the second charge V2 generated by the charging of the second charging current I2.
When the second charging current I2 charges the second electricity quantity V2 generated by the charging to the electricity quantity virtual storage module, the third current I3 is output, wherein the third current I3 is less than 20mA, and the third current I3 is the current output by the electricity quantity virtual storage module when the second charging current I2 is charged to the electricity quantity virtual storage module. Specifically, in the charging process of the mobile terminal every preset time T, the battery is charged by the third current I3 and the first charging current I1, and since the third current I3<20mA is much smaller than the first charging current I1<2A, the third current I3 can be ignored, and the normal charging current of the battery can be controlled to be I1< 2A.
And 204, dynamically setting n preset storage upper limit values of the second electric quantity according to a preset curve function and the current battery electric quantity every preset time, wherein the larger the current battery electric quantity is, the smaller the preset storage upper limit value is, and n is a natural number larger than 1.
For example, the preset upper storage limit V2(max) of the virtual storage power amount of the power amount virtual storage module in n stages is different, the n stages dynamically and virtually store the second power amount, and the preset upper storage limit V2(max) of the second power amount virtually stored by the power amount virtual storage module gradually decreases as the power amount of the battery gradually increases. For example, when the battery power is close to full charge (e.g., 98% of full charge), the power virtual storage module is turned off, and power is controlled to enter the battery, so as to protect the battery.
In some embodiments, the dynamically setting n preset storage upper limit values of the second electric quantity according to a preset curve function and a current battery electric quantity every preset time includes:
acquiring the current battery capacity of the battery at preset time intervals;
calculating the current to-be-charged electric quantity of the battery according to the current electric quantity of the battery;
setting m preset storage upper limit values of the second electric quantity according to the first percentage of the current electric quantity to be charged and the preset curve function, wherein m is less than n, and a constant coefficient in the preset curve function is set to be a real number between 0 and 1; and
and setting n-m preset storage upper limit values of the second electric quantity according to a second percentage of the current electric quantity to be charged and the preset curve function, wherein the second percentage is smaller than the first percentage, and a constant coefficient in the preset curve function is set to be a real number larger than 1.
For example, the virtual electricity storage module dynamically obtains a preset storage upper limit value V2(max) of a virtual storage electricity quantity according to a preset curve function, the virtual electricity storage module obtains a to-be-charged electricity quantity to be charged by the battery, namely, a difference (100% -Q%) between a full electricity quantity 100% of the battery and a current battery electricity quantity Q%, the virtual electricity storage module obtains a preset storage upper limit value V2(max) of m phases of virtual storage electricity quantity of 80% of the to-be-charged electricity quantity (100% -Q%) of the battery, namely, the virtual electricity storage module obtains m electricity quantity virtual storage upper limits on the preset curve function, and then V2(max)11> V2(max)12>,.., > V2(max) (m).
Wherein, the preset curve function can be expressed as:
f(t)＝a-t(ii) a Wherein a is a constant coefficient, a represents the decreasing radian of the curve, and the larger a, the larger the radian of the curve is; t is a corresponding time point on the curve, and a time interval between every two adjacent time points is a preset time T, for example, the preset time T is T ═ T2-t1Wherein t is1And t2Are the corresponding time points on the curve.
For example, when the virtual electric quantity storage module virtually stores the second electric quantity in m stages, the preset curve function f (t) ═ a-tThe medium constant coefficient a is 0<a<1, the preset storage upper limit value V2(max) of the second electric quantity virtually stored by the electric quantity virtual storage module at the preset time T is relatively large, such as V2(max)>200mV, i.e. V2(max)11>V2(max)12>，...，>V2(max)(m)>200mV。
When the electric quantity virtual storage module outputs V2(max) (m) rapidly, the electric quantity virtual storage module continues to virtually store a second electric quantity V2 at the same time, namely the electric quantity virtual storage module virtually stores electric quantity continuously, the electric quantity virtual storage module controls large current to be charged continuously for a long time and simultaneously outputs V2(max) (m) to the battery terminal rapidly, and rapid charging of the battery is met.
For example, when 80% of the amount of electricity to be charged (100% -Q%) to be charged by the battery is charged, the processor outputs an interrupt switching signal to the virtual electricity storage module, the virtual electricity storage module switches to a stage of charging 20% of the amount of electricity to be charged (100% -Q%) to be charged by the battery, and the virtual electricity storage module charges by the preset curve function f (t) ═ a%-tWherein a is>Dynamically taking (n-m) preset storage upper limit values V2(max) (n-m) of virtual storage electric quantity, wherein 1 is<m<n，V2(max)(n-m)<50mV, then 50mV>V2(max)21>V2(max)22>，...，>V2(max) (n-m), the preset of the second power amount virtually stored by the power amount virtual storage moduleThe storage upper limit value V2(max) is gradually decreased, and when the battery capacity approaches full charge (for example, 98% of full charge), the capacity virtual storage module is turned off, so as to control the capacity to enter the battery and protect the battery.
In some embodiments, the instantaneously outputting the second electric quantity to the battery when the second electric quantity is accumulated to the preset upper storage limit value, so that the first electric quantity and the second electric quantity are accumulated to form a battery electric quantity, includes:
controlling the electric quantity virtual storage module to accumulate the second electric quantity once every preset time to reach a corresponding preset storage upper limit value;
and outputting the second electric quantity accumulated from the first time to the nth time to the battery in sequence and instantly so that the first electric quantity and the second electric quantity accumulated from the first time to the nth time are accumulated to form the electric quantity of the battery.
For example, when the second electric quantity V2 virtually stored by the electric quantity virtual storage module accumulates to the preset storage upper limit value V2(max), the electric quantity virtual storage module instantly outputs V2(max) to the battery terminal to rapidly charge the battery. In the charging process of the mobile terminal, the second electric quantity V2 virtually stored by the electric quantity virtual storage module accumulates for several times to a preset storage upper limit value V2(max), and if the V2(max) is different, the electric quantity virtual storage module dynamically and virtually stores the second electric quantity in stages. That is, the larger the current battery power at each interval time T is, the smaller the second power V2 of the virtual storage is
During the charging process of the mobile terminal, the electric quantity virtual storage module outputs the accumulated second electric quantity V2(max) in a segmented manner to the battery end quickly so as to enable the battery to be charged fully, and the second electric quantity V2 stored in the electric quantity virtual storage module accumulates 1 time of electric quantity every preset time T to reach a preset storage upper limit value V2 (max). At the preset time T, the current of the battery for normal charging is a first charging current I1<2A, when the second electric quantity V2 virtually stored by the electric quantity virtual storage module reaches a preset storage upper limit value V2(max) and is instantly output to the battery end, the first charging current I1<2A of the instant charging current I >3A which is the preset time T and the second charging current I2>1A of the virtual storage electric quantity are charged together by I1 and I2, so that the mobile terminal does not need to continuously output the large current I >3A for a long time to charge the battery end, and the battery is quickly charged by the electric quantity virtual storage module at the same time, so that the large current is controlled to be continuously output for a long time, and the mobile terminal is greatly protected from being damaged by the large current during charging.
For example, the virtual electricity storage module accumulates 1 second electricity V2 to a preset storage upper limit value V2(max) at a preset time T, and V2 is less than V2(max), and during the charging process of the mobile terminal, the virtual electricity storage module (n-1) accumulates n second electricity to the preset storage upper limit value at a preset time T, that is, the virtual electricity storage module virtually stores the second electricity through n stages, and controls the large-current long-time continuous charging. For example, the preset time T is T <10ns (nanoseconds), the interval time T is relatively small, and the accumulation process of the second charge can be nearly instantaneously completed.
In some embodiments, the power virtual storage module is turned off when the battery power reaches a preset battery power.
For example, the preset upper storage limit V2(max) of the virtual storage power amount of the power amount virtual storage module in n stages is different, the n stages dynamically and virtually store the second power amount, and the preset upper storage limit V2(max) of the second power amount virtually stored by the power amount virtual storage module gradually decreases as the power amount of the battery gradually increases. For example, when the battery power is close to full charge (e.g., 98% of full charge), the power virtual storage module is turned off, and power is controlled to enter the battery, so as to protect the battery.
All the above optional technical solutions may be combined arbitrarily to form optional embodiments of the present application, and are not described herein again.
In particular implementation, the present application is not limited by the execution sequence of the described steps, and some steps may be performed in other sequences or simultaneously without conflict.
As can be seen from the above, in the charging control method provided in the embodiment of the present application, when the total charging current of the mobile terminal is greater than the preset current value, the virtual storage module for electric quantity is turned on, where the total charging current includes a first charging current and a second charging current; controlling a first charging current to charge the battery to generate a first amount of power in the battery; controlling the second charging current to virtually store the second charging current in the electric quantity virtual storage module so as to generate a second electric quantity in the electric quantity virtual storage module; when the second electric quantity is accumulated to a preset storage upper limit value, the second electric quantity is instantly output to the battery, so that the first electric quantity and the second electric quantity are accumulated to form the electric quantity of the battery. The embodiment of the application is in mobile terminal heavy current charging process, the battery normally charges with first charging current, and the virtual storage module of electric quantity is shunted to the second charging current that exceeds, the second electric quantity of virtual storage accumulates to the storage upper limit a plurality of times, in charging process, the second electric quantity of this accumulation of segmentation output arrives the battery end fast, so that the battery is full of the electricity fast, mobile terminal need not export heavy current to battery charging for a long time in succession, greatly protect mobile terminal not receive heavy current charging damage, in order to promote battery charge rate, prolong battery life.
