Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic diagram illustrating connection of an internal battery of an electronic device according to a battery charging method provided in an embodiment of the present invention. The electronic device 100 has 2 rechargeable batteries, wherein 1 rechargeable battery is a first battery 200 and can be charged quickly, such as a graphene battery, and the other 1 rechargeable battery is a second battery 300, and under the same charging conditions, the charging speed is slower than that of the first battery 200, such as a lithium battery. Note that the first battery 200 is not limited to 1, and the second battery 300 is not limited to 1; the invention can also be applied to a scenario that 2 groups of rechargeable battery packs are built in the electronic device, wherein 1 group is a first battery pack, and the other 1 group is a second battery pack, wherein the charging speed of the first battery pack is faster than that of the second battery pack. For convenience of description, 1 first battery 200 and 1 second battery 300 are taken as examples in this embodiment. The first battery 200 is electrically connected to the second battery 300, and the first battery 200 can be used to charge the second battery 300, and conversely, the second battery 300 can also be used to charge the first battery 200, controlled by the charging switch. The first battery 200 is charged to the second battery 30 by default. The electronic device preferentially selects the first battery 200 as the power source, and the second battery 300 is enabled as the power source only when the first battery 200 has a small amount of remaining power.
The electronic apparatus 100 includes an electronic data processing device that can be used in mobile, such as a smartphone, a tablet computer, and a notebook computer.
Referring to fig. 2, fig. 2 is a schematic diagram illustrating an implementation flow of a battery charging method according to an embodiment of the present invention, where the method is applicable to an electronic device. The method comprises the following steps:
101. when the electric quantity of the first battery is larger than or equal to the preset electric quantity, determining the next charging time point for charging the electronic device through the external power supply according to the historical charging information;
because the first battery is charged quickly, in order to make the electronic device obtain sufficient electric quantity as soon as possible, the first battery is charged by the external power supply. The external power source includes a power source from outside the electronic device, such as an indoor power source or a charger.
When the electric quantity of the first battery is greater than or equal to the preset electric quantity, for example, 90% or more of the electric quantity, it can be considered that the second battery is charged by the first battery when a certain electric quantity of the first battery is maintained, thus not only ensuring that the first battery can maintain the power consumption requirement of the electronic device, but also charging the second battery, because the redundant electric quantity of the first battery is used for charging the second battery, when the first battery is charged by using an external power supply later, the charging time required for fully charging the first battery is shorter than that of the second battery, so that the time for charging the two batteries in the electronic device by using the external power supply later is reduced.
The next charging time point for charging the electronic device by the external power supply is determined based on historical charging information, which may be information within a certain period of time in the past, for example, 30 days, or more 100 days, or less 3 days, etc. The historical charging information may include: historical charging time points, charging time periods, charged amounts and the like.
102. Acquiring historical power consumption information from the current time to the next charging time point;
the historical power consumption information may be historical power consumption information of a specified time period, or historical power consumption information of a latest time period, that is, the historical power consumption information is information of a time point from the current time to the next charging time point charged by the external power supply every day on the collection date, and for example, the current time is 17: 00, the next charging time point is 19: 00, the collection date is 10 days in the past, and the historical power consumption information is 17: 00-19: 00.
the historical power consumption information includes: information related to power consumption, such as historical usage information of the electronic terminal and power consumption amount corresponding to the historical usage information. Further, the historical usage information may include names, durations, and the like of used APPs, where the APPs may be system APPs including network connections, or third party APPs such as games and videos.
103. Determining the reserved electric quantity of the first battery according to the historical power consumption information and a preset reserved electric quantity rule;
the reserved electric quantity is the lowest remaining electric quantity reserved by the first battery after the second battery is charged. That is, the current capacity of the first battery is a minimum value excluding the capacity charged to the second battery and the capacity remaining after excluding the capacity consumed in the process of charging the second battery.
The reserved electric quantity rule may specifically be a corresponding relationship between the estimated electric power consumption and the reserved electric quantity, specifically a positive relationship. The estimated power consumption is the power consumption consumed by the first battery in the process of charging the second battery, and is related to using the electronic device, if the APP running in the electronic device is more or the running time is long, the estimated power consumption is large, and if the APP running in the electronic device is long, the corresponding reserved power is large, and vice versa. Specifically, the reserved electric quantity corresponding to the estimated electric power consumption can be obtained by inquiring the corresponding relation between the estimated electric power consumption and the reserved electric quantity in the reserved electric quantity rule. In order to prevent the second battery from being charged too much if the actual power consumption exceeds the estimated power consumption, the reserved power of the first battery cannot maintain the basic power consumption of the electronic device.
For example, if the current electric quantity of the first battery is 100%, the estimated electric consumption is 30%, and the reserved electric quantity is 20%, the electric quantity charged to the second battery is 50%; the current electric quantity of the first battery is 90%, the estimated electric consumption is 40%, the reserved electric quantity is 25%, and the electric quantity charged to the second battery is 25%
Further, the reserved power rule may also be a fixed reserved power, and the reserved power is 30% no matter what the estimated power consumption is. The reserved electric quantity rule is preset in the system.
104. And controlling the first battery to charge the second battery, and controlling the first battery to stop charging the second battery when detecting that the residual electric quantity of the first battery is less than or equal to the reserved electric quantity.
In the embodiment of the invention, when the electric quantity of the first battery is higher than the preset electric quantity, the next charging time point for charging the electronic device by an external power supply is determined according to the historical charging information, the historical power consumption information corresponding to the next charging time point from the current time is obtained, the reserved electric quantity of the first battery is determined according to the historical power consumption information and the reserved electric quantity rule, the first battery is controlled to charge the second battery, when the residual electric quantity of the first battery is detected to be less than or equal to the reserved electric quantity, the first battery stops charging the second battery, the electronic device is charged by the first battery while the power consumption of the electronic device is ensured, the second battery is charged under the non-inductive state without influencing the use of a user, and when the electronic device is charged by the external power supply, the electric quantity of the second battery is increased, and the charging time of the first battery is short, therefore, compared with the situation that the electric quantity of the second battery is not increased, the time for charging the second battery which is longer than the charging time of the first battery is shorter through the external power supply, so that the total charging time of the two batteries is reduced, the charging efficiency is improved, and the user experience is also improved.
Referring to fig. 3, fig. 3 is a schematic view illustrating an implementation flow of a battery charging method in another embodiment provided in the embodiment of the present invention, where the method is applicable to an electronic device, and a first battery and a second battery are built in the electronic device, and the first battery is electrically connected to the second battery, and the first battery can charge the second battery. The method mainly comprises the following steps:
201. when detecting that the electric quantity of the second battery is smaller than the preset electric quantity to be charged, detecting whether the electric quantity of the first battery is larger than or equal to the preset electric quantity;
the charge amount is a preset charge amount value of the second battery.
It should be noted that, when the first battery needs to be charged, the system may switch to the second battery to supply power to the electronic device, at this time, if the user enters the room, the first battery with a relatively fast charging speed is charged by the external power supply, and at this time, the electric quantity of the second battery may be smaller than the electric quantity that needs to be charged.
When the electric quantity of the second battery is smaller than the preset electric quantity to be charged, the first battery is required to charge the second battery, whether the electric quantity of the first battery reaches the preset electric quantity is detected, namely whether the electric quantity is larger than or equal to the preset electric quantity is detected, if the electric quantity reaches the preset electric quantity, the step 202 is executed, if the electric quantity does not reach the preset electric quantity, the external power supply is firstly used for charging the first battery, and after the electric quantity of the first battery reaches or is higher than the preset electric quantity, the step 202 is executed.
Specifically, the preset electric quantity to be charged can obtain historical charging information by the electronic device, and find information such as the time point and the time length of charging the first battery to the second battery in the historical period and the electric quantity after charging in the historical period, and calculate the corresponding electric quantity to be charged when the electric quantity after charging is optimal to be used as the preset electric quantity to be charged.
For example, it can be confirmed that the optimal charging amount is 90%, which neither requires the first battery to fully charge the second battery, which may cause the first battery to allocate more electric power to the second battery, thereby failing to satisfy the power consumption requirement of the electronic terminal in the charging period, nor causes the charging time of the external power supply to be prolonged due to insufficient electric power from the first battery to the second battery when the user arrives indoors and starts to charge the second battery through the external power supply. The amount of electricity to be charged corresponding to 90% of the optimum value of the amount of electricity to be charged is 50% of the amount of electricity, so that the preset amount of electricity to be charged is determined to be 50%.
202. When the electric quantity of the first battery is larger than or equal to the preset electric quantity, determining the next charging time point for charging the electronic device through the external power supply according to the historical charging information;
specifically, the present charging record is obtained, the historical charging record with the highest coincidence degree with the present charging record is obtained, the charging time point corresponding to the current time in the historical charging record is searched, and the charging time point closest to the current time is used as the next charging time point for charging the electronic device through the external power supply. The accuracy of confirming the time point can be improved.
Finding the historical charging record with the highest coincidence degree of the charging time point and the charging duration in the charging record and the present day, and searching the closest charging time point which is not reached yet in the historical charging record as the next charging time point, for example, now 17: 00, the charging time points of the historical charging records by the external power supply are 10: 00. 16: 00. 20: 00. 24: 00, etc., then 20: 00 is the next charging time point.
Or obtaining historical daily power consumption information with the highest coincidence degree with the current daily power consumption information, obtaining historical daily charging records corresponding to the historical daily power consumption information, searching for charging time corresponding to the current time in the historical daily charging records, and taking the charging time closest to the current time as the next charging time point
The power consumption information comprises used APP, use duration and the like, the closer the power consumption information is to the power consumption, and the accuracy of confirming the next charging time point can be further improved by confirming the next charging time point according to the historical charging record corresponding to the historical power consumption information with the highest coincidence degree.
203. Acquiring historical power consumption information from the current time to the next charging time point;
204. determining the reserved electric quantity of the first battery according to the historical power consumption information and a preset reserved electric quantity rule;
specifically, historical usage information of the electronic device from the current time to the next charging time point and the power consumption amount corresponding to the historical usage information are acquired. The historical use information refers to the use condition of the electronic device in a past period, and comprises the name, the time point, the time length and the like of the APP used by the electronic device. The past period of time may be system set or user specified.
The power consumption amount from the current time to the next charging time point is estimated in comparison with the usage history information and the power consumption amount corresponding to the history usage information. The user may plan a time point and a duration of using the APP by the electronic device, for example, browsing a web page on the road, listening to music, watching short videos for 1 hour, etc., from a current time to a next charging time point of charging the electronic device through the external power supply. And confirming the power consumption corresponding to the historical use information with the highest coincidence degree of the time point and the time length of the APP planned to be used as the power consumption from the current time to the next charging time point according to the time point and the time length of the APP used in the use historical information.
Further, can set up the APP that power consumption is close into same type APP and compare, improve degree of accuracy and flexibility. For example, class a APPs include A, B, C, D four APPs that are close in power consumption, and when the "a" APP is used in the query plan, B, C, D three APPs are also included in the comparison process as query results.
And determining the reserved electric quantity corresponding to the estimated electric consumption in the reserved electric quantity rule as the reserved electric quantity of the first battery. Specifically, the reserved electric quantity corresponding to the estimated electric power consumption is inquired in the reserved electric quantity rule, and the inquired reserved electric quantity is determined as the reserved electric quantity of the first battery. For example, if the estimated power consumption is 30% and the corresponding reserved power amount is 20%, the reserved power amount of the first battery is 20%, and the power amount charged to the second battery is the surplus power amount obtained by subtracting the sum of the estimated power consumption and the reserved power amount from the current power amount.
205. Detecting the current electric quantity of the first battery, comparing whether the difference between the current electric quantity and the estimated electric consumption is larger than or equal to a preset threshold value, and determining whether the second battery is charged according to the comparison result;
in order to reduce the risk that the first battery charges the second battery to supply power to the second battery, whether the current residual capacity of the first battery is enough is detected.
Specifically, if the difference between the current remaining power and the estimated power consumption is greater than or equal to a preset threshold, the first battery is controlled to charge the second battery.
If the difference between the current residual capacity and the estimated power consumption is smaller than a preset threshold, the first battery is not controlled to charge the second battery, or the power shared to the second battery is reduced, and the difference between the current residual capacity and the estimated power consumption is kept larger than or equal to the preset threshold.
206. And controlling the first battery to charge the second battery, and controlling the first battery to stop charging the second battery when detecting that the residual electric quantity of the first battery is less than or equal to the reserved electric quantity.
Further, in the process that the first battery charges the second battery, the battery temperatures of the first battery and the second battery are detected in real time, and if the battery temperature of any one of the first battery and the second battery is greater than a preset temperature value, the first battery is stopped charging the second battery.
Or detecting whether a preset high-power-consumption application runs in real time or not, or detecting whether the running application number is larger than the preset number or not, and if the preset high-power-consumption application runs or the running application number is larger than the preset number, stopping the first battery from charging the second battery. The high power applications can be automatically classified by the system or set by the user, and usually the high power applications comprise some game class and video class applications.
The above detection of the battery temperature and the application in the electronic device can control the possibility that the battery continues to be internally charged even if the battery is overheated, thereby increasing the safety.
This embodiment is not described in detail with reference to the previous description of the embodiment shown in fig. 2.
In the embodiment of the invention, when the electric quantity of the second battery is detected to be smaller than the preset electric quantity to be charged, whether the electric quantity of the first battery reaches the preset electric quantity is detected, if not, the external power supply is used for charging the first battery, the electric quantity of the first battery is prevented from being insufficient, so that the electric quantity of the electronic device is maintained while the second battery is charged, when the electric quantity of the first battery reaches the preset electric quantity, the next charging time point for charging the electronic device by the external power supply is determined according to the historical charging information, the accuracy of determining the next charging time point is improved, furthermore, the historical power consumption information corresponding to the next charging time point from the current time to the next charging time point is obtained, the reserved electric quantity of the first battery is determined according to the historical power consumption information and the reserved electric quantity rule, the first battery is controlled to be charged to the second battery, when the residual electric quantity of the first battery is detected to be smaller than or equal, stop first battery to second battery charging, when guaranteeing that electron device is power consumptive, charge for the second battery through first battery, accomplish the charging to the second battery under the noninductive state that does not influence the user to use, and, when rethread external power source charges for electron device, because the second battery has increased the electric quantity, and first battery is the charge time again short, consequently compare under the circumstances that the second battery does not increase the electric quantity, charge for the second battery that is longer than first battery charge time through external power source, the time spent is shorter, thereby reduced these two blocks of battery total time of charging, charging efficiency is improved, user experience has also been improved.
