Fig. 1 is a schematic flow chart of a charging method provided in the present application. The charging method provided by 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.
And the actual battery capacity is the theoretical maximum capacity corresponding to the current battery of the terminal.
Optionally, the terminal may obtain the current remaining capacity and the actual battery capacity based on the collected data such as the voltage and the current of the battery of the terminal.
The current remaining power of the terminal refers to the current remaining power of the terminal.
As the terminal is used, the battery of the terminal may suffer from an aging phenomenon, which is expressed as a decrease in the actual battery capacity of the battery. Therefore, in order to ensure more accurate control of the charging time, the theoretical maximum capacity currently corresponding to the battery of the terminal may be acquired as the actual battery capacity, instead of taking the rated maximum capacity of the battery of the terminal as the actual battery capacity.
According to the current remaining capacity and the actual battery capacity, the amount to be charged can be obtained.
The amount to be charged refers to an amount of electricity required to fully charge the battery of the terminal from the current remaining amount of electricity. The amount 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, an appropriate range of charging current allowed by the terminal exists, and therefore, based on the range of the charging current and the amount to be charged, the shortest time and the longest time required for charging the battery of the terminal from the current remaining capacity to the current corresponding theoretical maximum capacity can be determined and respectively taken as the shortest full charge time and the longest full charge time and output.

Alternatively, the user may select and input a time from a time range determined by the shortest full charge time and the longest full charge time as the target full charge time. Thus, the first input may carry a target full charge time.
Optionally, the first input may carry a relative magnitude relationship between the target full charge time and the minimum full charge time and/or the maximum full charge time.
The above-mentioned relative magnitude 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 the average of the shortest full charge time and the longest full charge time, and the like.
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 that the first input carries the target full charge time, the response mode to the first input may include: a target full charge time is extracted from the first input, thereby determining the target full charge time.
Optionally, after receiving the first input, in a case that the first input carries a relative magnitude relationship between the target full charge time and the shortest full charge time and/or the longest full charge time, the response mode to the first input may include: the target time is determined based on the relative magnitude relationship 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.
And 104, determining a charging parameter based on the target full charge time, the current residual capacity and the actual battery capacity.
Alternatively, after the shortest full charge time and the longest full charge time are output, the user may perform a selection operation based on the shortest full charge time and the longest full charge time, selecting one time from a time range consisting of the shortest full charge time and the longest full charge time as the target full charge time.
According to this 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 may be determined according to the target full charge time and the amount to be charged based on the charging characteristics of the battery.
And 105, charging the terminal based on the charging parameters.
Optionally, after the charging parameter is determined, the charging process of the terminal may be controlled based on the charging parameter, and the terminal may be charged, so that the terminal may be fully charged when the charging duration reaches the target full charging time.
The full charge time range determined by the shortest full charge time and the longest full charge time is output, a 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 more accurately controlled, the full charge time of the terminal is better matched with the selected target full charge time of the user, and therefore different requirements of quickly supplementing electricity or slowing down the aging speed of the battery and the like of the user are met.
Optionally, the obtaining of the charging parameter based on the target full charge time, the current remaining power and the actual battery capacity specifically includes: and determining the target charging current and the 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 this embodiment of the application, since the terminal may output the shortest full charge time and the longest full charge time, it is described that trickle charging is not required for charging the terminal, 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% -soc0) ═ C (Icc) ((1-exp (-a Tcv))/a/60+ Icc (Tcc) (+) Tcc)
Equation 3: t ═ Tc + Tcv
Wherein Tcv represents a target charging time in the constant voltage charging phase; ln represents an operation symbol of a natural logarithm; icc represents the target charging current for the constant current charging phase; i represents the off current, 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 the target charging time of the constant current charging phase; t denotes the target full charge time.
After obtaining T, a, I, soc0, C, Tcc, Tcv, and Icc can be obtained according to the 3 formulas described above.
Since the target full charge time T is determined, Tcc and Icc can be used as charging parameters, and after the constant current charging with the time length of Icc being performed by Icc, a constant voltage charging stage is entered until the total charging time length 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 duration of Tcv is carried out after constant-current charging with the duration of Tcc is carried out by the Icc, and the terminal is just fully charged when the total charging duration reaches the target full-charging time T.
It should be noted that 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 denotes the initial charging current of the constant voltage charging phase; t represents time; a is a coefficient.
The value of a can be determined by fitting according to the charging process of a test battery of the same type as the battery of the terminal.
According to the charging method and the charging device, charging parameters such as target charging current and target charging time in a 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, 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 better matched with the target full charging time selected by a user.
Optionally, the method for outputting the shortest full charge time and the longest full charge time based on the current remaining capacity 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 capacity and the actual battery capacity.
Alternatively, step 101 may be triggered by a different trigger condition, in which case step 101 is executed.
The triggering condition of step 101 may be that the terminal is switched from an uncharged state to a charged state.
The switching of the terminal from the uncharged state to the charged state may include the case where the terminal is connected to an energized charger, and the case where the connected terminal charger is switched from the uncharged state to the energized state.
According to the embodiment of the application, 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 obtained, a user can select the target full charge time at the first time, and the charging control can be performed more conveniently.
Optionally, the method specifically includes, based on the current remaining power and the actual battery capacity of the terminal, outputting the shortest full charge time and the longest full charge time before: a second input is received.
Alternatively, the triggering condition of step 101 may be that a second input is received.
The second input can be input to the terminal by the user at any time between the start of charging the terminal and the full charge, so that the user can set the target full charge time (the target full charge time is not set before) or change the originally set target full charge time (the target full charge time is set before) in the charging process besides setting the target full charge time at the start 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, the shortest full charging time and the longest full charging time are triggered to be obtained, the target full charging time can be selected by a user when the user needs the target full charging time, and charging control can be performed more conveniently and flexibly.
Optionally, the shortest full charge time is obtained in a case where the charging in the constant current charging stage is performed with a preset maximum charging current; the maximum full charge time is obtained when the charging is performed in the constant current charging phase at a preset minimum charging current.
Optionally, the process of charging the terminal from the current remaining power to the actual battery capacity is composed of a constant-current charging stage and a constant-voltage charging stage, the increasing rate of the power in the constant-current charging stage is constant, and the increasing rate of the power in the constant-voltage charging stage is gradually decreased, so that the duration of the constant-current charging stage in the full charging time is a main influence factor of the full charging time, and the duration of the constant-voltage charging stage is a secondary influence factor of the full charging time.
Therefore, the shortest full charge time corresponds to the case of performing the constant current charging with the maximum charging current, and the longest full charge time corresponds to the case of performing the constant current charging with the minimum charging current.
The maximum charging current and the minimum charging current are preset to ensure that the charging will not damage the battery of the terminal.
According to the embodiment of the application, the shortest full charge time is obtained under the condition that the charging in the constant current charging stage is carried out by using the preset maximum charging current, and the longest full charge time is obtained under the condition that the charging in the constant current charging stage is carried out by using the preset minimum charging current, so that the provided full charge time range is more accurate, the full charge time of the terminal can be more accurately controlled, and the full charge time of the terminal is better matched with the target full charge time selected by a user.
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: and determining a first constant voltage charging time and a first constant voltage charging capacity according to the preset maximum charging current and the preset cutoff current, and determining a second constant voltage charging time and a second constant voltage charging capacity according to the preset minimum charging current and the preset cutoff current.
Alternatively, the change of the charging current with the charging time in the constant-voltage charging satisfies I ═ I0 × exp (-a × t), and therefore, the time Tcv and the charging capacity Ccv of the constant-voltage charging phase 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 denotes the initial charging current of the constant voltage charging phase; t represents time; a is a coefficient; ln represents the arithmetic sign of the natural logarithm.
Since the time of the constant-voltage charging phase is Tcv, constant integration between 0 and Tcv is performed in a calculation manner 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 completed, and the charging current in the constant-current charging phase is the initial charging current in the constant-voltage charging phase.
Therefore, in order to obtain the shortest full charge time, constant current charging may be performed at the maximum charging current Imax, and the first constant voltage charging time Tcv1 and the first constant voltage charging capacity Ccv1 may be obtained by substituting Imax as I0 into the calculation formulas of Tcv and Ccv.
In order to obtain the maximum full charge time, constant current charging may be performed at the minimum charging current Imin, and the second constant voltage charging time Tcv2 and the second constant voltage charging capacity Ccv2 may be obtained by substituting Imin as I0 into the calculation formulas of Tcv and Ccv.
And determining the first constant current charging time according to the current residual electric quantity, the actual battery capacity, the first constant voltage charging time and the first constant voltage charging capacity, and determining the second constant current charging time according to the current residual electric quantity, the actual battery capacity, the second constant voltage charging time and the second constant voltage charging capacity.
Alternatively, the calculation formula of the amount to be charged C1 is C1 ═ (100% -soc0) × C.
Wherein 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.
In order to obtain the shortest full charge time, the charging capacity cc1 of the constant current charging phase is C1-Ccv1, and therefore, the first constant current charging time Tcc1 may be calculated by the following formula:
Tcc1＝Ccc1/Imax
in order to obtain the maximum full charge time, the charging capacity cc2 of the constant current charging stage is C1-Ccv2, and therefore, the second constant current charging time Tcc2 may be calculated by the following formula:
Tcc2＝Ccc2/Imin
it is understood that the second constant current charging time Tcc2 is the longest charging time Tccmax of the constant current charging phase.
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 may be calculated by the following formula:
Tmax＝Tcv2+Tcc2
according to the embodiment of the application, the shortest full charge time is obtained under the condition that the charging in the constant current charging stage is carried out by using the preset maximum charging current, and the longest full charge time is obtained under the condition that the charging in the constant current charging stage is carried out by using the preset minimum charging current, so that the provided full charge time range is more accurate, the full charge time of the terminal can be more accurately controlled, and the full charge time of the terminal is better matched with the target full charge time selected by a user.
Optionally, the displaying the shortest full charge time and the longest full charge time specifically includes: scroll bars ending with the shortest full charge time and the longest full charge time are 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.
Alternatively, 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 to the sliding control in the scroll bar, and responding to the input to obtain the target charging time.
Optionally, as shown in FIG. 2, scrollbar 201 may contain a slider control 204. The first input is a user input to a slider control 204 in scrollbar 201.
The user can input by dragging the slider control 204 based on the UI, and the target position of the slider control 204 is input.
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 end point 202 can be obtained, and the target charging time T is calculated according to the following formula:
T＝Tmin+S*(Tmax-Tmin)/S0
wherein Tmax represents the maximum full charge time; tmin represents the minimum full charge time; s0 represents the distance between the first endpoint 202 and the second endpoint 203.
Optionally, the target charging time T is displayed in the UI.
Optionally, the full 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 target charging time is determined according to the position of the sliding control in the scroll bar selected by the user by displaying the scroll bar taking the shortest full charging time and the longest full charging time as endpoints, so that the target charging 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 full charge time.
And obtaining the default value of the target full charge time according to the current residual capacity and the actual battery capacity based on the charging history 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 according to the current remaining capacity and the actual battery capacity based on a history of charging or based on a preset target algorithm.
The history of charging may be reflected in the user's preference to select a target full charge time, and thus a default value for the target full charge time may be determined according to the user's preference.
For example: in the previous 10 times of charging processes, the user selects the shortest full charge time as the target full charge time for 8 times, which indicates that the user has more demands for quick charging, 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 target full charge time is close to or equal to the shortest full charge time is selected by the user to be 4 times, the number of times that the target full charge time is close to or equal to the longest charge time is 3 times, and the other times are 3 times, which indicates that the requirements of the user are more variable, 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.
A default value for the target full charge time may also be determined based on a target algorithm based on the current remaining capacity and the actual battery capacity.
Optionally, the target algorithm is an algorithm that takes into account fast charging and slow battery aging speed.
