Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Along with the continuous promotion of terminal equipment's the speed of charging, the multiplying power that charges of lithium cell also constantly promotes, but the charge and discharge of big multiplying power has great influence to the performance of battery, for example: the battery life may be reduced or the battery capacity of the battery may be reduced.
When the battery in the terminal equipment is a single battery cell, in order to avoid the influence of the improvement of the charging rate on the performance of the battery, the charging rate of the battery can be controlled, that is, the charging rate of the battery in actual use is smaller than the charging rate in design, or the energy density of the battery is reduced in the design stage of the battery cell.
But the charging speed of the battery is reduced by the scheme of controlling the charging rate of the battery; and the capacity of the battery is reduced by the scheme of reducing the energy density.
In order to solve the above technical problem, the present disclosure provides a battery control method.
Fig. 1 is a flowchart illustrating a battery control method according to an exemplary embodiment, as shown in fig. 1, the method including the following steps S101-S103:
in step S101, the battery is charged at a first charging current.
In step S102, when it is detected that the charging state reaches a preset condition, charging the battery according to a preset charging mode; the second charging current corresponding to the preset charging mode is smaller than the first charging current.
In one implementation, the state of charge reaching the preset condition includes: the number of charging cycles of the first charging current reaches a second preset number.
For example: and the number of charging cycles adopting the first charging current is more than or equal to 2 weeks, and at the moment, when the number of charging cycles adopting the first charging current is detected to be more than or equal to 2 weeks, the battery is charged according to a second charging current corresponding to a preset charging mode.
Wherein, a charge cycle means that the charge capacity of the battery reaches 100% in total.
In another implementation, the state of charge reaching the preset condition includes: the number of times of charging of the first charging current reaches a third preset number of times.
For example: and the charging frequency of the first charging current reaches any value of 5-50 times, and at the moment, when the charging frequency adopting the first charging current is detected to be more than or equal to 5 times and less than or equal to 50 times, the battery is charged according to a second charging current corresponding to a preset charging mode.
When the first charging current corresponds to the charging current during quick charging, at the moment, after the battery is quickly charged for a plurality of times, the battery is charged by adopting the second charging current corresponding to the preset charging mode.
The charging times of the first charging current is limited, so that the charging can be carried out through the small current in time, the surface of the battery can be enabled to react in more sufficient time, partial by-products generated when the large current is adopted for charging are reduced, the performance of the battery core is improved, and the performance of the battery is effectively improved.
In step S103, when the number of charging cycles for charging according to the preset charging mode reaches a first preset number, the charging with the first charging current is resumed.
For example, the first preset number may be greater than or equal to 1, and when the number of charging cycles for charging according to the preset charging mode is greater than or equal to 1, after the cycles are completed, the charging speed is recovered to the original speed, that is, the charging is recovered by using the first charging current.
In the process of charging by adopting the first charging current, the charging mode can be changed into the mode of using the second charging current corresponding to the preset charging mode smaller than the first charging current to continue charging the battery, because the battery is charged by using the small current smaller than the first charging current, the battery surface can be enabled to have more sufficient time to react, thereby partial by-products generated when the large current is adopted for charging can be reduced, the improvement of the performance of the electric core is facilitated, the service life of the battery can be effectively prolonged, the reduction of the battery capacity of the battery is avoided, and further the performance of the battery is effectively improved.
However, since the second charging current corresponding to the preset charging mode is smaller than the first charging current, when the battery is charged by adopting the second charging current corresponding to the preset charging mode, the charging speed can be obviously smaller than the charging speed for charging by adopting the first charging current, so that the charging capacity of the second charging current corresponding to the preset charging mode can be obviously reduced in the same time, and the user experience is poor, therefore, a first preset number of times can be set for charging by using the second charging current corresponding to the preset charging mode, when the charging cycle number for charging by using the second charging current corresponding to the preset charging mode reaches the first preset number of times, the charging by using the larger first charging current is recovered, and therefore, the user experience is effectively improved on the premise of improving the performance of the battery.
Wherein, the second charging current corresponding to the preset charging mode is smaller than the first charging current, for example: the first current may be 70%, or may be 60%, 50%, or other values of the first current, and the disclosure does not limit the specific value of the first current.
The first charging current may be a charging current of the terminal device in a normal charging mode, or may be a charging current of the terminal device in a fast charging mode.
Fig. 2 is a graph of experimental data illustrating the use of the battery control method of the present disclosure according to an exemplary embodiment. As shown in fig. 2, it can be seen that after one normal temperature cycle test is applied, the capacity of the battery is obviously increased, and the improvement gradually becomes more obvious as the number of cycles increases, and it can be seen that at 700 cycles, the capacity of the battery recovered by the scheme is increased by 50mAh, and the effect is obvious.
The technical scheme provided by the embodiment of the disclosure can have the following beneficial effects: charging the battery according to the first charging current, and charging the battery according to a preset charging mode when the charging state is detected to reach a preset condition; and when the charging cycle times of charging according to the preset charging mode reach the first preset times, the charging by adopting the first charging current is resumed. Because the process of charging by adopting the first charging current can be changed into the process of continuously charging by adopting the smaller second charging current, partial by-products generated when the charging is carried out by adopting the large current can be reduced, the improvement of the performance of the electric core is facilitated, and the performance of the battery is effectively improved.
At present, the battery type in the terminal equipment includes not only the single-cell scheme described above, but also a scheme in which multiple cells are connected in series.
When a battery in the terminal equipment is connected in series by multiple battery cores, as the times of high-rate charge and discharge are increased, voltage differences among the battery cores can be caused, and the voltage differences not only have great influence on the performance of the battery, but also can even bring about safety problems such as battery explosion and the like. In order to avoid influencing the performance of the battery and causing safety problems, the imbalance of each battery cell is relieved mainly through the charging stage of quick charging, but along with the acceleration of the charging speed, the charging time is shorter, and the relieving capacity is weaker, so that the balancing capacity between the battery cells is weaker, the performance of the battery cannot be effectively improved, and the safety problems are avoided.
For the scheme of serially connecting a plurality of battery cells, the serially connected battery cells not only require single performance, but also require voltage uniformity of the plurality of battery cells, but the voltage uniformity difference is larger as the charging current is larger, and the voltage difference between the battery cells is accumulated under a large current for a long time. The charging of small current in the charging process is controlled, so that the voltage consistency of the two batteries can be realized within a longer time in the whole charging process.
Fig. 3 is a graph showing experimental data before improvement according to an exemplary embodiment, and fig. 4 is a graph showing experimental data using the battery control method in the present disclosure according to an exemplary embodiment. The scheme of the disclosure has a great improvement effect on two batteries connected in series. As shown in fig. 3 and 4, in order to compare the effects before and after the improvement, according to the two serial schemes, at a larger charging speed (charging according to the first charging current), the current charging mode (as shown in fig. 3) can be seen to have a significant capacity reduction after 150 weeks, and the data degradation of the cycle capacity of the battery is increased. However, after the introduction of the improvement of the present application, it was observed that the entire cycle trend was stable for up to 350 weeks. And simultaneously, comparing the capacity of 200 weeks, the circulating capacity before improvement is about 1485mAh, and the improved circulating capacity is improved to 1520mAh, so that the circulating capacity is obviously improved.
For the scheme that a plurality of battery cells are connected in series, detecting that the charging state reaches the preset condition includes not only the above two implementation manners, but also: the voltage difference between any two electric cores reaches a preset voltage value.
Taking an example that two battery cells are connected in series, when the voltage difference between the two battery cells reaches 50mV, the battery is charged by using a second charging current corresponding to the preset charging mode.
For a single-cell or multi-cell scheme, charging a battery according to a preset charging mode at least comprises the following three implementation modes:
the first method comprises the following steps: and charging the battery according to the second charging current.
In this method, a battery is charged with a small current during a long-term normal charging interval.
And when the second charging current is adopted for charging, the second charging current is adopted for charging the battery in the whole charging process. For example: when the number of charging cycles using the first charging current reaches 35 times, the battery is charged in a preset charging mode during the entire charging process at 36 th time.
The first charging current charging described above may be understood as a large-rate charging, and the second charging current charging may also be understood as a small-rate charging. After the lithium battery is charged and discharged with a large multiplying power, the lithium battery is charged and discharged with a small multiplying power. For example, when normal charging reaches a high rate of 1C or more, a small rate charge-discharge cycle of 0.7C or less is performed for the battery system.
And the second method comprises the following steps: and when the electric quantity of the battery reaches the preset electric quantity, charging the battery by using the second charging current.
The mode mainly aims at the condition that the whole charging stage can not be realized, and can be adjusted in partial charging stages.
Continuing with the above example, during the 36 th charging process, when the battery charge reaches 60%, the remaining 40% of the battery charge is charged by the predetermined charging pattern. In this way, the charging is performed by using a small current in stages at the rear part of the charging, and in this way, although the whole charging time is prolonged, the single cell can be recovered, and the balance of the double cells can be more complete.
And the third is that: and charging the battery according to the first charging current when the electric quantity of the battery does not reach the preset electric quantity.
The mode is also adjusted aiming at the condition that the whole charging stage can not be realized, and can be adjusted in partial charging stage.
Continuing with the above example, during the 36 th charging process, when the charging capacity of the battery does not reach 40%, i.e., the battery is charged in the initial charging stage by using the preset charging mode, the battery is charged by using the first charging current when the charging capacity reaches 40%. In this way, the charging is performed by using a small current in stages in the front of the charging, and in this way, although the whole charging time is prolonged, the single cell can be recovered, and the balance of the double cells can be more complete.
In the second and third solutions, the service life of the battery can be prolonged without affecting normal use and while maintaining a large charging speed.
The implementation is described in detail by the following examples.
First, the battery is charged at a first charging current.
Then, when the charging state is detected to reach a preset condition, charging the battery according to a preset charging mode; the second charging current corresponding to the preset charging mode is smaller than the first charging current.
Wherein, detecting that the charging state reaches a preset condition comprises:
the voltage difference between any two electric cores reaches a preset voltage value; or the charging cycle number of the first charging current reaches a second preset number; or the charging frequency of the first charging current reaches a third preset frequency.
Charging the battery according to a preset charging mode, comprising:
charging the battery according to the second charging current; or when the electric quantity of the battery reaches the preset electric quantity, charging the battery by using a second charging current; or when the electric quantity of the battery does not reach the preset electric quantity, the battery is charged according to the first charging current.
And finally, when the charging cycle times according to the preset charging mode reach a first preset time, the charging is resumed by adopting the first charging current.
The following are embodiments of the disclosed apparatus that may be used to perform embodiments of the disclosed methods.
