Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure.
In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of the present disclosure. The embodiments described below by referring to the drawings are exemplary and intended for the purpose of explaining the present disclosure and are not to be construed as limiting the present disclosure. Based on the embodiments in this disclosure, all other embodiments that a person of ordinary skill in the art would obtain without making any inventive effort are within the scope of protection of this disclosure. Embodiments of the present disclosure are described in detail below with reference to the attached drawings.
The method for controlling the starting of the terminal, which is provided by the embodiment of the disclosure, can be applied to a starting scene of a terminal charging process. For example, the method can be applied to a terminal self-starting scene that a terminal battery is charged from an overdischarge state to meet the terminal starting requirement. Of course, it can also be applied to other scenarios, to which the present disclosure is not particularly limited.
At present, the charging technology is applied to various fields and is widely applied to various electronic products.
In the related art, if a terminal (e.g., a mobile phone) performs a start-up procedure during a charging process, a power supply loop performs a short-time power-off, and starts up power for the terminal through a terminal battery during the power-off period. On this basis, the voltage of the battery cell will generally directly affect the starting result of the terminal. For example, if the voltage of the battery cell is higher than the minimum supply voltage for terminal start, the terminal can start smoothly. For another example, if the voltage of the battery cell is lower than the minimum supply voltage for the terminal to start, the terminal may have a risk of start failure. Therefore, the terminal needs to be smoothly started under the condition that the battery cell is charged to a voltage meeting the starting requirement. However, due to the influence of the hardware structure and layout of the terminal, the real-time voltage of the battery cell cannot be directly known, so that the terminal is easy to fail in starting due to insufficient voltage of the battery cell.
In the related art, a voltage acquisition point can be set in a charging loop of a terminal, and a fixed voltage threshold is set for real-time voltage acquired by the voltage acquisition point, wherein the fixed voltage threshold is set based on an empirical value and is used for representing the minimum voltage acquired by the voltage acquisition point when the terminal is successfully started. Further, the voltage detection of the battery cells is replaced by monitoring the voltage of the voltage acquisition point.
However, since the charging current of the terminal is generally variable, the voltage carried by the impedance between the voltage collection point and the battery cell generally varies due to the change of the charging current, so that the minimum voltage collected at the voltage collection point changes when the terminal is successfully started. For example, if the minimum voltage corresponding to the battery cell is V when the terminal is successfully started bat The impedance between the voltage acquisition point and the battery cell is R, and the charging current flowing through the impedance is I 1 The theoretical value of the minimum voltage of the voltage acquisition point when the terminal is successfully started is I 1 *R+V bat . If the charging current flowing through the impedance is I 1 Setting a fixed voltage threshold of the voltage acquisition point as I 1 *R+V bat And the charging current flowing through the impedance between the voltage acquisition point and the battery cell is represented by I 1 Increase to I 2 Then the voltage carried by the impedance is represented by I 1 * R is increased to I 2 * R, when the voltage acquisition point acquires a voltage greater than a fixed voltage threshold, the voltage of the battery cell is smaller than V bat And the risk of start-up failure of the terminal. If the charging current flowing through the impedance between the voltage acquisition point and the battery cell is I 1 Reduced to I 3 Before the voltage which is acquired by the voltage acquisition point and is larger than the fixed voltage threshold value, the voltage of the battery cell reaches V bat The voltage of the battery core meets the starting requirement of the terminalThe terminal has not been triggered to start, resulting in a later time node for the terminal to start. Therefore, in the related art, the manner of setting a fixed voltage threshold for the real-time voltage acquired by the voltage acquisition point cannot meet the actual use requirement of the control terminal for starting.
In view of this, the embodiments of the present disclosure provide a method for controlling terminal start, which may determine, during charging of a terminal, a voltage threshold for triggering to start the terminal through a real-time charging current, so as to implement dynamic adjustment of the voltage threshold. Based on the method, whether the terminal meets the condition of triggering starting or not can be judged through the real-time voltage of the voltage acquisition point and the voltage threshold value of the matched real-time charging current, and the method can ensure that the terminal is started as soon as possible aiming at the condition that the terminal is charged by the charging current with any size, and the starting success rate of the terminal is considered, so that the actual use requirement of the terminal starting can be met, and the use experience of a user is improved.
For convenience of description, a voltage threshold set for a real-time voltage of a voltage acquisition point according to a real-time charging current input to a terminal battery cell is referred to as a first voltage threshold.
Fig. 1 is a flowchart illustrating a method of controlling terminal startup according to an exemplary embodiment, as shown in fig. 1, including the following steps.
In step S11, when the terminal is charged, the real-time voltage of the voltage acquisition point of the terminal is acquired, and the real-time charging current of the battery cell input to the terminal is acquired.
In embodiments of the present disclosure, the voltage collection point may be disposed at any node of the terminal charging loop (e.g., the voltage collection point may be connected in parallel to the positive and negative electrodes of the battery case to which the battery cell belongs). It can be understood that the set voltage acquisition point needs to have a relatively clear association relationship with the battery cell so as to know the impedance and/or the voltage between the voltage acquisition point and the battery cell. For example, a voltage acquisition component may be configured for a voltage acquisition point of the terminal in advance, and the voltage acquisition component may perform real-time voltage acquisition on the voltage acquisition point. In addition, in the charging process of the terminal, the charging current can be set by the control chip of the terminal in a self-defining way, so that the real-time charging current input to the battery cell can be directly obtained through the charging current currently set by the control chip.
In step S12, a first voltage threshold is determined based on the real-time charging current.
The first voltage threshold may be understood as a voltage corresponding to a voltage acquisition point when the terminal is successfully started, which is set according to the real-time charging current, for example, may be a minimum voltage corresponding to the voltage acquisition point when the terminal is successfully started.
In step S13a, if the real-time voltage acquired at the voltage acquisition point is greater than or equal to the first voltage threshold, the start terminal is triggered.
In the embodiment of the disclosure, since the charging loop of the terminal is known, the association relationship between the real-time voltage acquired by the voltage acquisition point and the real-time voltage of the battery cell can be obtained through deduction of the position of the voltage acquisition point and the battery cell in the charging loop. In other words, the real-time voltage collected at the voltage collection point may be used to estimate the real-time voltage of the battery cells.
In step S13b, if the real-time voltage acquired at the voltage acquisition point is less than the first voltage threshold, the start terminal is not triggered.
According to the method for controlling terminal starting provided by the embodiment of the disclosure, the voltage of the battery cell can be estimated to reach the minimum voltage capable of enabling the terminal to be started successfully by determining that the real-time voltage acquired by the voltage acquisition point is greater than or equal to the first voltage threshold, and under the condition, the starting terminal is triggered, so that the battery cell can be ensured to have enough voltage to supply power for terminal starting. And aiming at the condition that the real-time voltage acquired at the voltage acquisition point is smaller than the first voltage threshold value, the starting terminal is not triggered, and the method can ensure the starting success rate of the terminal and ensure the terminal to start as early as possible.
For example, the minimum voltage of the battery cell for the terminal to start may be known in advance according to the start requirement of the terminal system. Further, the minimum voltage may be used as a reference value, and the voltage carried by the impedance between the voltage collection point and the battery cell may be used as a voltage compensation value, where the minimum voltage that the voltage collection point may be used for terminal startup, i.e. the first voltage threshold, is estimated. For convenience of description, the voltage carried by the impedance between the voltage acquisition point and the battery cell is referred to as a first compensation voltage, and the minimum voltage corresponding to the battery cell when the terminal is successfully started is referred to as a second voltage threshold.
FIG. 2 is a flowchart illustrating a method of determining a first voltage threshold based on a real-time charging current, as shown in FIG. 2, according to an exemplary embodiment, including the following steps.
In step S21, a first compensation voltage is determined based on the real-time charging current and the impedance between the voltage acquisition point and the battery cell.
In the embodiment of the disclosure, the impedance between the voltage acquisition point and the battery cell can be calculated according to the components and the circuits connected between the voltage acquisition point and the battery cell in the charging loop, and the impedance obtained by calculation can be stored later for the terminal to call at any time. The components included between the voltage collection point and the battery cell may be, for example, a connector and/or a battery protection plate.
In step S22, the second voltage threshold is compensated with the first compensation voltage to obtain the first voltage threshold.
In the embodiment of the disclosure, the voltage corresponding to the battery cell when the terminal is successfully started, namely the second voltage threshold, can be obtained in advance according to the power supply voltage required by the starting of the terminal system. The second voltage threshold may be, for example, a minimum voltage corresponding to the battery cell when the terminal is started successfully. In addition, the first compensation voltage obtained by the impedance between the voltage acquisition point and the battery cell and the real-time charging current can be understood as the pre-estimated value of the real-time voltage currently carried by the impedance. Based on the above, the first compensation voltage can be used for compensating the second voltage threshold, so that the minimum voltage which can be correspondingly acquired at the voltage acquisition point when the terminal is successfully started, namely the first voltage threshold, is obtained.
For example, the first voltage threshold may be obtained by a sum of the first compensation voltage and the second voltage threshold under the condition that the first compensation voltage is determined by the real-time charging current and the impedance between the voltage acquisition point and the battery cell, so as to implement compensation for the second voltage threshold.
In the embodiment of the disclosure, the product of the real-time charging current and the impedance between the voltage acquisition point and the battery cell can be directly used as the first compensation voltage. Of course, a plurality of charging current intervals may be divided according to the adjustable range of the charging current, and then a maximum value of the interval to which the real-time charging current belongs is determined, and a product of the maximum value of the interval and the impedance between the voltage acquisition point and the battery cell is used as the first compensation voltage. The following is set forth in relation to two different ways of determining the first compensation voltage, respectively.
Fig. 3 is a flowchart of another method for determining a first voltage threshold based on a real-time charging current according to an exemplary embodiment, and as shown in fig. 3, step S32 in the embodiment of the present disclosure is similar to the implementation process of step S22 in fig. 2, and will not be described herein.
In step S31, the product of the real-time charging current and the impedance between the voltage acquisition point and the battery cell is used as the first compensation voltage.
The method for starting the control terminal provided by the embodiment of the disclosure can take the product of the real-time charging current and the impedance between the voltage acquisition point and the battery cell as the first compensation voltage, so that the first compensation voltage is attached to the real-time change condition of the charging current. Based on the method, no matter the terminal is charged by charging current with any size, the terminal can be started as soon as possible under the condition that the voltage of the battery core meets the starting requirement of the terminal, and the waiting time of a user can be reduced.
In another embodiment, a plurality of charging current intervals may be preset, and a target charging current interval to which the real-time charging current belongs in the plurality of preset charging current intervals may be determined. Based on this, the product between the maximum charging current and the voltage acquisition point of the target charging current section and the impedance can be taken as the first compensation voltage.
Fig. 4 is a flowchart of another method for determining a first voltage threshold based on a real-time charging current according to an exemplary embodiment, and as shown in fig. 4, step S44 in the embodiment of the present disclosure is similar to the implementation process of step S22 in fig. 2, and is not described herein.
In step S41, a plurality of preset charging current intervals are acquired.
For example, a plurality of nodes may be set in the adjustable range for the adjustable range of the charging current, and then the set plurality of nodes are used as boundary values (including an upper boundary value and a lower boundary value) of the charging current interval, so as to obtain a plurality of charging current intervals. For example, if the adjustable range of the charging current is I min To I max If respectively set I a I b Two nodes (example, I min ＜I a ＜I b ＜I max ) The charging current can be divided into [ I ] according to the adjustable range of the charging current min ，I a ]、(I a ，I b ](I) b ，I max ]Three charging current intervals. Based on this, the divided charging current intervals may be stored to be recalled when needed. Wherein it is understood that the set nodes and/or charging current intervals may be any number, which is not limited by the present disclosure.
In step S42, a target charging current interval to which the real-time charging current belongs in a plurality of preset charging current intervals is determined, and a maximum charging current of the target charging current interval is determined.
For example, to obtain [ I ] min ，I a ]、(I a ，I b ](I) b ，I max ]For example, if I is determined a ＜I＜I b (example, the real-time charging current is denoted by I), the target charging current interval to which the real-time charging current belongs can be determined as (I a ，I b ]. On the basis, the maximum charging current of the target charging current interval is I b 。
In step S43, the product of the maximum charging current and the impedance between the voltage acquisition point and the battery cell is used as the first compensation voltage.
It is understood that the maximum charging current refers to the maximum charging current of the target charging current section in step S42.
According to the method for controlling terminal starting provided by the embodiment of the disclosure, the first compensation voltage is determined according to the maximum charging current of the target charging current interval to which the real-time charging current belongs, and a reserved space with dynamic change (increase or decrease) can be provided for the real-time charging current. Based on the method, a unified first compensation voltage is set for the situation that the real-time charging current is increased or decreased in the same charging current interval, and compared with a mode of adjusting the first voltage threshold in real time, the method has smaller power consumption, and the method provides selectable items for balance consideration between power consumption and adjustment precision.
By way of example, can be made by V 1 ＝V bat +I chg * R, a first voltage threshold is obtained (shown in example as V 1 Representation). Wherein V is bat Represents a second voltage threshold, R represents the impedance between the voltage acquisition point and the battery cell, I chg The charging current used for determining the first compensation voltage is represented, and the charging current comprises a real-time charging current or a maximum charging current of a target charging current interval to which the real-time charging current belongs.
In general, due to problems of detection accuracy or calculation accuracy, a value obtained by a terminal through collection or calculation, for example, a real-time voltage collected at a voltage collection point, a real-time charging current flowing through an impedance, and/or a minimum voltage (i.e., a second voltage threshold) of a battery cell when the terminal is successfully started, is usually slightly deviated from an actual value, and the deviation generally affects an actual effect of starting the terminal. Taking the real-time charging current as an example, if the obtained real-time charging current is I c Whereas the actual real-time charging current is I d (illustratively, is influenced by the charging current regulation precision of the terminal, I c ＜I d ) The set first voltage threshold is lower than the actual first voltage threshold, in which case, if the real-time voltage of the voltage acquisition point is greater than or equal to the set first voltage threshold, and triggering Starting the terminal, the terminal may fail to start.
In an embodiment, after the second voltage threshold is compensated by the first compensation voltage, the compensated second voltage threshold is compensated again by the preset compensation voltage, so that the compensated second voltage threshold is consistent with the first voltage threshold. The present disclosure is hereinafter described for convenience of description, and a preset compensation voltage for re-compensating the second voltage threshold value is referred to as a second compensation voltage.
Fig. 5 is a flowchart of another method for determining a first voltage threshold based on a real-time charging current according to an exemplary embodiment, and as shown in fig. 5, step S51 in the embodiment of the present disclosure is similar to the implementation process of step S21 in fig. 2, and is not described herein.
In the embodiments of the present disclosure, the manner of determining the first compensation voltage based on the real-time charging current and the impedance between the voltage acquisition point and the battery cell is described in the above embodiments, and the related content may refer to any of the above embodiments.
In step S52, the second voltage threshold is compensated by the first compensation voltage, and the compensated second voltage threshold is compensated again by the second compensation voltage, so as to obtain the first voltage threshold.
It is understood that the second compensation voltage is a preset compensation voltage for compensating the voltage difference between the first voltage threshold and the compensated second voltage threshold.
In the embodiment of the disclosure, after the second voltage threshold is compensated by the first compensation voltage, the sum value between the second compensation voltage and the compensated second voltage threshold may be used as the first voltage threshold to implement the second voltage threshold compensation again.
By way of example, can be made by V 1 ＝V bat +I chg * R+ΔV, a first voltage threshold (shown in example as V 1 Representation). Wherein V is bat Represents a second voltage threshold, R represents voltage acquisitionImpedance from point to cell, I chg The charging current used for determining the first compensation voltage is represented, and the charging current comprises a real-time charging current or a maximum charging current of a target charging current interval to which the real-time charging current belongs.
In the embodiment of the present disclosure, the preset second compensation voltage may be set in advance by a start result of the terminal. For example, the second voltage threshold may be compensated by the first compensation voltage, and the compensated second voltage threshold may be set as the first voltage threshold. Based on this, the setup terminal triggers the start-up terminal only if the real-time voltage at the voltage acquisition point is determined to be the first voltage threshold. If the terminal fails to start, the set first voltage threshold is smaller than the actual value to be set by the first voltage threshold, and the set first voltage threshold is gradually increased until the terminal can start successfully. On the basis, the difference between the set value of the first voltage threshold when the terminal is successfully started and the initial set value of the first voltage threshold can be used as a second voltage threshold, and the determined second voltage threshold is stored later to compensate the data acquisition or calculation precision of the terminal later.
Fig. 6 is a schematic diagram illustrating a scenario in which a terminal performs a first voltage threshold adjustment according to a real-time charging current, according to an exemplary embodiment.
In the embodiment of the disclosure, as shown in fig. 6, the terminal may perform, by using the control module, adjustment of the first voltage threshold when detecting that the charger is connected. The control module may be understood as a component having a control function in the terminal, for example, a central processing unit (Central Processing Unit, CPU) of the terminal. For example, during charging of the terminal, the control module may set and adjust the charging current of the terminal. In other words, the terminal can directly learn the real-time charging current from the voltage acquisition point to the battery cell according to the charging current currently set by the control module. On the basis, on the one hand, the real-time voltage acquisition can be performed at a voltage acquisition point through the voltage acquisition component. On the other hand, the first voltage threshold may be updated in real time by the real-time charging current.
