All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The charging method, the charging device, the electronic equipment and the storage medium provided by the embodiment of the application are described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of a charging method provided in the present application. The charging method provided in the embodiment of the present application is described below with reference to fig. 1. As shown in fig. 1, the method includes:
and step 101, outputting the shortest full charge time and the longest full charge time based on the current residual capacity and the actual battery capacity of the terminal.
The actual battery capacity is the theoretical maximum capacity corresponding to the battery of the terminal.
Alternatively, the terminal may acquire the current remaining capacity and the actual battery capacity based on the acquired data such as the voltage and current of the battery of the terminal.
The current residual capacity of the terminal refers to the current residual capacity of the terminal.
With the use of the terminal, the battery of the terminal may undergo aging phenomena, which are manifested as a decrease in the actual battery capacity of the battery. Therefore, in order to ensure that the charging time can be controlled more accurately, the theoretical maximum capacity of the battery of the terminal, which corresponds to the present state, may be obtained as the actual battery capacity, instead of taking the rated maximum capacity of the battery of the terminal as the actual battery capacity.
The to-be-charged amount may be obtained based on the current remaining amount and the actual battery capacity.
The waiting charge amount refers to the amount of electricity required for charging the battery of the terminal from the current residual amount to full charge. The amount of charge to be charged is equal to the difference between the actual battery capacity and the current remaining capacity.
In order to ensure that the battery of the terminal is not damaged by charging, a proper range exists for the charging current allowed by the terminal, so that the shortest time and the longest time required for charging the battery of the terminal from the current residual electric quantity to the current corresponding theoretical maximum capacity can be determined and respectively used as the shortest full charge time and the longest full charge time to be output based on the range of the charging current and the to-be-charged electric quantity.
Alternatively, the shortest full charge time and the longest full charge time may be output for display on a screen of the terminal.
Step 102, a first input is received.
The first input is input by the user based on the shortest fill time and the longest fill time.
A first input for determining a target full charge time.
Alternatively, the user may select one time from a time range determined by the shortest full charge time and the longest full charge time as the target full charge time and input. Thus, the first input may carry a target full charge time.
Alternatively, the first input may carry a relative magnitude relationship between the target full charge time and the shortest full charge time and/or the longest full charge time.
The above relative size relationship is a quantitative relationship, for example: the target full charge time is 15 minutes longer than the shortest full charge time, or the target full charge time is 20% shorter than the longest full charge time, or the target full charge time is an average of the shortest full charge time and the longest full charge time, etc.
Step 103, in response to the first input, determining a target full charge time.
Wherein the target full charge time is not less than the shortest full charge time and not more than the longest full charge time.
Optionally, after receiving the first input, in a case where the first input carries the target full charge time, a response manner to the first input may include: a target fill time is extracted from the first input to determine the target fill time.
Optionally, after receiving the first input, in a case where the first input carries a relative magnitude relation between the target full charge time and the shortest full charge time and/or the longest full charge time, the responding manner to the first input may include: the target time is determined based on a relative magnitude relation between the target full charge time and the shortest full charge time and/or the longest full charge time, and the shortest full charge time and/or the longest full charge time.
Step 104, determining a charging parameter based on the target full charge time, the current residual capacity and the actual battery capacity.
Optionally, after outputting the shortest full charge time and the longest full charge time, the user may perform a selection operation based on the shortest full charge time and the longest full charge time, and select one time from a time range formed by the shortest full charge time and the longest full charge time as the target full charge time.
According to the selection operation by the user, the target full charge time can be determined.
After the target full charge time is determined, charging parameters such as a charging current and the like may be determined according to the target full charge time and the to-be-charged amount based on the charging characteristics of the battery.
And 105, charging the terminal based on the charging parameters.
Optionally, after determining the charging parameter, the charging process of the terminal may be controlled based on the charging parameter to charge the terminal, so that the terminal may be fully charged when the charging duration reaches the target full charge time.
According to the embodiment of the application, the full charge time range determined by the shortest full charge time and the longest full charge time is output, the user selects one time from the full charge time range as the target full charge time, the charging parameter is determined according to the target full charge time, the terminal is charged based on the charging parameter, the terminal can be just fully charged under the condition that the charging time reaches the target full charge time, the full charge time of the terminal can be controlled more accurately, the full charge time of the terminal is matched with the selected target full charge time of the user better, and therefore different requirements of the user on quick charge or battery aging speed reduction are met.
Optionally, based on the target full charge time, the current remaining capacity and the actual battery capacity, acquiring the charging parameters specifically includes: and determining a target charging current and a target charging time in the constant-current charging stage as charging parameters according to the target full charging time, the current residual capacity, the actual battery capacity and the preset cut-off current.
Optionally, in the embodiment of the present application, since the terminal may output the shortest full charge time and the longest full charge time, it is indicated that the charging of the terminal does not need to perform trickle charging, and constant current charging may be performed first, and then constant voltage charging may be performed.
The charging characteristics of the battery of the terminal can be described by the following 3 formulas:
equation 1: tcv=ln (Icc/I)/a
Equation 2: (100% -soc 0) ×c=icc (1-exp (-a×tcv))/a/60+icc
Equation 3: t=tcc+tcv
Wherein Tcv represents a target charging time in the constant voltage charging stage; ln represents the operation sign of natural logarithm; icc represents a target charging current at a constant current charging stage; i represents the cut-off current, which is a known fixed value; a is a coefficient obtained in advance; c represents the actual battery capacity; soc0 represents the percentage of the current remaining capacity to the actual battery capacity, and soc0×c is the current remaining capacity; tcc represents a target charging time of the constant current charging stage; t represents the target full charge time.
After T, a, I, soc, C are obtained, tcc, tcv and Icc can be obtained according to the 3 formulas described above.
Since the target full charge time T is already determined, tcc and Icc can be used as charging parameters, and after constant current charging with the duration of Icc is performed with Icc, a constant voltage charging stage is entered until the total duration of charging reaches the target full charge time T, and the terminal is just fully charged.
And the Tcc, the Tcv and the Icc can be used as charging parameters, constant-voltage charging with the Tcv is carried out after constant-current charging with the Tcc with the Icc time length, and the terminal is just fully charged when the total charging time length reaches the target full charging time T.
The change of the charging current in the constant voltage charging stage with the charging time satisfies
I＝I0*exp(-a*t)
Wherein I represents an off-current; i0 represents an initial charging current in the constant voltage charging stage; t represents time; a is a coefficient.
The value of a can be determined by fitting according to the charging process of the test battery of the same type as the battery of the terminal.
According to the method and the device, the charging parameters such as the target charging current and the target charging time in the constant-current charging stage are obtained according to the target full charging time, the current residual capacity, the actual battery capacity and the preset cut-off current, the obtained charging parameters are more accurate, so that charging according to the charging parameters can be achieved, when the total charging time reaches the target full charging time, the terminal is just fully charged, the full charging time of the terminal can be controlled more accurately, and the full charging time of the terminal is matched with the target full charging time selected by a user better.
Optionally, outputting the shortest full charge time and the longest full charge time based on the current remaining power and the actual battery capacity of the terminal specifically includes: and under the condition that the terminal is switched from the uncharged state to the charged state, determining and displaying the shortest full charge time and the longest full charge time based on the current residual electric quantity and the actual battery capacity.
Alternatively, step 101 may be triggered by a different trigger condition, in which case step 101 is performed.
The triggering condition of step 101 may be that the terminal switches from an uncharged state to a charged state.
The terminal being switched from the uncharged state to the charged state may include the terminal being connected to a charger that is energized, and the connected terminal charger being switched from the uncharged state to the energized state.
According to the embodiment of the invention, the terminal is switched from the uncharged state to the charged state, the shortest full charge time and the longest full charge time are triggered to be acquired, and a user can select the target full charge time at the first time, so that the charging control can be more conveniently carried out.
Optionally, before outputting the shortest full charge time and the longest full charge time based on the current remaining power and the actual battery capacity of the terminal, the method specifically includes: a second input is received.
Alternatively, the trigger condition of step 101 may be the receipt of a second input.
The second input may be input to the terminal by the user at any time between when the terminal starts to charge and when the terminal is fully charged, so that the user can set the target full charge time (the target full charge time is not set before) in the charging process or change the originally set target full charge time (the target full charge time is set before) in addition to the target full charge time set at the beginning of charging.
After receiving the second input, step 101 is performed in response to the second input.
According to the embodiment of the application, the terminal receives the charging time setting instruction, and triggers the acquisition of the shortest full charge time and the longest full charge time, so that the user can select the target full charge time when the user needs the charging time, and the charging control can be more conveniently and flexibly carried out.
Alternatively, the shortest full charge time is obtained in the case of charging in the constant current charging stage with a preset maximum charge current; the maximum full charge time is obtained when the constant current charging phase is charged with a preset minimum charge current.
Optionally, the process of charging the terminal from the current residual electric quantity to the actual battery capacity comprises a constant-current charging stage and a constant-voltage charging stage, wherein the electric quantity in the constant-current charging stage is constant in increasing rate, and the electric quantity in the constant-voltage charging stage is gradually reduced in increasing rate, so that the duration of the constant-current charging stage in full charging time is a main influencing factor of the full charging time, and the duration of the constant-voltage charging stage is a secondary influencing factor of the full charging time.
Therefore, the shortest full charge time corresponds to the case of constant current charging with the largest charge current, and the longest full charge time corresponds to the case of constant current charging with the smallest charge current.
The maximum charging current and the minimum charging current are preset in order to ensure that the charging does not damage the battery of the terminal.
According to the method and the device for achieving the constant-current charging, the shortest full-charge time is obtained under the condition that the constant-current charging stage is carried out by the preset maximum charging current, the longest full-charge time is obtained under the condition that the constant-current charging stage is carried out by the preset minimum charging current, the provided full-charge time range is more accurate, the full-charge time of the terminal can be controlled more accurately, and the full-charge time of the terminal is matched with the target full-charge time selected by a user better.
Optionally, determining the shortest full charge time and the longest full charge time based on the current remaining power and the actual battery capacity specifically includes: the first constant voltage charging time and the first constant voltage charging capacity are determined according to a preset maximum charging current and a preset cutoff current, and the second constant voltage charging time and the second constant voltage charging capacity are determined according to a preset minimum charging current and a preset cutoff current.
Alternatively, the change of the charging current at the time of constant voltage charging with the charging time satisfies i=i0×exp (-a×t), and therefore, the time Tcv and the charging capacity Ccv of the constant voltage charging stage can be obtained by the following formulas, respectively
Tcv＝Ln(I0/I)/a
Ccv＝∫Idt＝∫I0*exp(-a*t)dt
Wherein I represents an off-current; i0 represents an initial charging current in the constant voltage charging stage; t represents time; a is a coefficient; ln represents the sign of the natural logarithm.
Since the constant voltage charging period takes a period of Tcv, a constant integration between 0 and Tcv is performed in accordance with the calculation method of Ccv, and ccv=i0 (1-exp (-a×tcv))/a/60 can be obtained. The unit of charge capacity is mAh.
It is understood that the constant-voltage charging is performed after the constant-current charging is ended, and the charging current in the constant-current charging stage is the initial charging current in the constant-voltage charging stage.
Therefore, in order to obtain the shortest full charge time, constant current charging may be performed at the maximum charging current Imax, imax is substituted as I0 into the calculation formulas of Tcv and Ccv, and the first constant voltage charging time Tcv1 and the first constant voltage charging capacity Ccv1 may be obtained.
In order to obtain the longest full charge time, constant current charging may be performed with the minimum charge current Imin, substituting Imin as I0 into calculation formulas of Tcv and Ccv, and obtaining the second constant voltage charge time Tcv2 and the second constant voltage charge capacity Ccv2.
The first constant-current charging time is determined according to the current residual capacity, the actual battery capacity, the first constant-voltage charging time and the first constant-voltage charging capacity, and the second constant-current charging time is determined according to the current residual capacity, the actual battery capacity, the second constant-voltage charging time and the second constant-voltage charging capacity.
Alternatively, the calculation formula of the to-be-charged amount C1 is c1= (100% -soc 0) ×c.
Wherein C represents an actual battery capacity; soc0 represents the percentage of the current remaining capacity to the actual battery capacity, and soc0×c is the current remaining capacity.
In order to obtain the shortest full charge time, the charge amount cc1=c1 to Ccv1 in the constant current charge phase, and therefore, the first constant current charge time Tcc1 can be calculated by the following formula:
Tcc1＝Ccc1/Imax
in order to obtain the longest full charge time, the charge amount cc2=c1 to Ccv2 in the constant current charge phase, and therefore, the second constant current charge time Tcc2 can be calculated by the following formula:
Tcc2＝Ccc2/Imin
it can be understood that the second constant current charging time Tcc2 is the longest charging time Tccmax of the constant current charging stage.
And determining the shortest full charge time according to the first constant voltage charge time and the first constant current charge time, and determining the longest full charge time according to the second constant voltage charge time and the second constant current charge time.
Alternatively, the minimum full charge time Tmin may be calculated by the following formula:
Tmin＝Tcv1+Tcc1
the maximum full charge time Tmax can be calculated by the following formula:
Tmax＝Tcv2+Tcc2
according to the method and the device for achieving the constant-current charging, the shortest full-charge time is obtained under the condition that the constant-current charging stage is carried out by the preset maximum charging current, the longest full-charge time is obtained under the condition that the constant-current charging stage is carried out by the preset minimum charging current, the provided full-charge time range is more accurate, the full-charge time of the terminal can be controlled more accurately, and the full-charge time of the terminal is matched with the target full-charge time selected by a user better.
Optionally, displaying the shortest full charge time and the longest full charge time specifically includes: a scroll bar ending in the shortest full charge time and the longest full charge time is displayed on a screen of the terminal.
Alternatively, as shown in fig. 2, a scroll bar 201 may be displayed in a User Interface (UI) of the terminal.
The scroll bar 201 contains two endpoints: a first endpoint 202 representing the shortest full charge time and a second endpoint 203 representing the longest full charge time.
Optionally, the shortest full charge time is displayed in the UI adjacent to the first endpoint 202 and the longest full charge time is displayed in the UI adjacent to the second endpoint 203.
And receiving input of a user on a sliding control in the scroll bar, and responding to the input to obtain the target charging time.
Alternatively, as shown in FIG. 2, the scroll bar 201 may contain a slider control 204. The first input is a user input to a slider control 204 in the scroll bar 201.
The user may enter the target position of the slider control 204 by dragging the slider control 204 based on the UI.
According to the target position of the sliding control 204, the distance S between the target position of the sliding control 204 and the first endpoint 202 may be obtained, and the target charging time T may be calculated according to the following formula:
T＝Tmin+S*(Tmax-Tmin)/S0
wherein Tmax represents the longest full charge time; tmin represents the shortest full charge time; s0 represents the distance between the first end point 202 and the second end point 203.
Optionally, the target charging time T is displayed in the UI.
Optionally, a fill time obtained from the real-time position of the slider control 204 is displayed in the UI.
According to the embodiment of the application, the scroll bar taking the shortest full charge time and the longest full charge time as endpoints is displayed, and the target charge time is determined according to the position of the sliding control in the scroll bar selected by the user, so that the target charge time can be determined more simply and conveniently.
Optionally, the initial position of the slider control in the scroll bar represents a default value for the target fill time.
The default value of the target full charge time is obtained according to the current residual electric quantity and the actual battery capacity based on a history of charging or based on a preset target algorithm.
Alternatively, before determining the target full charge time, a default value may be obtained as the target full charge time recommended to the user based on the history of charging or based on a preset target algorithm, according to the current remaining capacity and the actual battery capacity.
The history of charging may be reflected in a user's preference for selecting a target full charge time, and thus a default value for the target full charge time may be determined based on the user's preference.
For example: in the first 10 charging processes, 8 times of users select the shortest full charge time as the target full charge time, which means that the users have more requirements on quick charge, and the shortest full charge time can be determined as a default value of the target full charge time; the number of times that the user selects the target full charge time to be close to or equal to the shortest full charge time is 4 times, the number of times that the target full charge time is close to or equal to the longest full charge time is 3 times, and other conditions are 3 times, so that the requirements of the user are changeable, and the average value of the shortest full charge time and the longest charge time can be determined as the default value of the target full charge time.
The default value of the target full charge time may also be determined based on a target algorithm based on the current remaining charge and the actual battery capacity.
Alternatively, the target algorithm is an algorithm that combines both fast charge and slow battery aging.
