Detailed Description
In order to make the object, technical solution and merits of the present invention clearer, the present invention will be illustrated in detail hereinafter with reference to the accompanying drawings and specific examples.
In embodiments of the present invention, current remaining charging time of a mobile device is obtained and displayed according to a non-linear equation. Examples of mobile devices that can be used in accordance with various embodiments include, but are not limited to, a tablet PC (including, but not limited to, Apple iPad and other touch-screen devices running Apple iOS, Microsoft Surface and other touch-screen devices running the Windows operating system, and tablet devices running the Android operating system), a mobile phone, a smartphone (including, but not limited to, an Apple iPhone, a Windows Phone and other smartphones running Windows Mobile or Pocket PC operating systems, and smartphones running the Android operating system, the Blackberry operating system, or the Symbian operating system), an e-reader (including, but not limited to, Amazon Kindle and Barnes & Noble Nook), a laptop computer (including, but not limited to, computers running Apple Mac operating system, Windows operating system, Android operating system and/or Google Chrome operating system), or an on- vehicle device running any of the above-mentioned operating systems or any other operating systems, all of which are well known to those skilled in the art.
Figure 1 is a schematic diagram illustrating a method of performing charging processing for a mobile device according to an example of the present invention. Referring to Figure 1, the method includes following processes.
In process 101, a non-linear equation related to a charging time variable and a charge percentage variable is obtained, and a current charge percentage is obtained.
In various embodiments, during a procedure of charging the mobile device, the mobile device obtains the current charge percentage.
For the mobile device, the charge percentage and charging time are non-linear during the procedure of charging the mobile device. In the example of the present invention, the non-linear equation applicable to general cases is obtained through collecting a mass of charging data.
The non-linear equation may be generated by a network side device, and the mobile device may obtain the non-linear equation from the network side device as required. A method of generating the non-linear equation includes:
collecting history charging data including the charge percentage and charging time corresponding to the charge percentage, and generating the non-linear equation related to the charge percentage variable and the charging time variable through fitting the history charging data.
A method of collecting the history charging data includes: collecting the charge percentage Pi5 and taking charging time of charging the mobile device from Pj to Pi+B as charging time Tj corresponding to the charge percentage Pi, where B is a predefined charge increment value, for example, 1 % , and i is a natural number. After the charging data (Pi5 Tj) is collected, the non-linear equation F(P)=T is generated by fitting the charging data according to an interpolation algorithm such as a Lagrange interpolation algorithm or a Newton interpolation algorithm.
In process 102, remaining charging time is calculated according to the current charge percentage and the non-linear equation.
In various embodiments, the current charge percentage is indicated as Pi, and the charging time of charging the mobile device from Pj to Pj+B is indicated as .
The remaining charging time may be calculated according to Pi and
F(P)=T.
Specifically, Pi+kB is substituted into the non-linear equation F(P)=T to obtain Tk, where k is an integer among 0 to M and Pi+MB is smaller than or
M
S=∑TK
equal to 100 % , the sum of Tk, k=0 , is calculated, and S is taken as the remaining charging time.
Charging conditions in practical charging procedures may be different. In order to make the remaining charging time more accurate, the remaining charging time is adjusted in an example of the present invention. Specifically, a method of adjusting the remaining charging time includes:
substituting Pi+kB into the non-linear equation F(P)=T to obtain Tk, where k is an integer among 0 to M and Pi+MB is smaller than or equal to
M
S =∑TK
100 % , calculating the sum of Tk, k=0 , taking TVTi as an adjustment parameter, and taking a product of multiplying S by TVTi as the remaining charging time.
In process 103, the remaining charging time is displayed.
In various embodiments, the remaining charging time may be displayed on the screen of the mobile device.
In order to display a current charging state, after the current charge percentage is obtained in process 101 shown in Figure 1, the method further includes: determining the charging state according to the current charge percentage, and displaying the charging state on the screen of the mobile device. The charging state includes a fast charging state, a continuous charging state and a trickle charging state. A range of the charge percentage in the fast charging state is 0%~80%, a range of the charge percentage in the continuous charging state is 80%~100%, and a range of the charge percentage in the trickle charging state is 100% and the mobile device continues to be charged for a period of time after the charge percentage reaches 100%.
After the charging procedure ends, if a charging cable is still connected to a power supply, the battery will be overcharged. Overcharging will influence the life of the battery. Accordingly, in an example of the present invention, an alarm clock prompt is triggered after the charging procedure ends. Specifically, after the current charge percentage is obtained in process 101, the method further includes: determining whether the current charge percentage is equal to 100%. If the current charge percentage is equal to 100%, the alarm clock prompt is triggered.
The solution provided by the example of the present invention may be implemented by a charging client running in an operation system of the mobile device. After the mobile device boots, the operation system sends a boot command to the charging client, and after receiving the boot command, the charging client determines whether the non-linear equation has been saved; if no, process 101 is performed, and if yes, it is indicated that the non-linear equation has been obtained. Correspondingly, obtaining the current charge percentage in process 101 includes: calling a system information interface, and obtaining the current charge percentage from the operation system. The operation system provides an open system information interface for processes running in the operation system. Each process may obtain system information through calling the system information interface. The system information includes the current charge percentage.
The operation system not only provides the open system information interface but also provides an open system drawing interface. The displaying the remaining charging time in process 103 shown in Figure 1 includes: the charging client calls the system drawing interface, selects a format interface, input the remaining charging time in the format interface, generates a displaying interface, and displays the displaying interface on the screen of the mobile device. The system drawing interface is used for drawing the displaying interface. Through calling the system drawing interface, the charging client may select the format interface from multiple format interfaces provided by the operation system, and inputs different information in different regions of the format interface according to the prompt of the format interface. For example, the remaining charging client is inputted.
In order to enrich the display of the format interface, in an example of the present invention, multiple displaying interfaces may be generated and saved, and then a selected displaying interface is displayed as required by the user. Specifically, at least two format interfaces are selected, and information contents are inputted into each format interface to generate a displaying interface. The inputted information contents include the remaining charging time. Other contents may also be inputted into each format interface as required. For example, the current charge percentage is inputted into one format interface, and current time is inputted into the other format interface. A format interface identity corresponding to each displaying interface is generated and each displaying interface is saved. Afterwards, a prompt box for prompting the user to select a format interface is displayed, selecting information including a format interface identity inputted by the user is received, and a displaying interface corresponding to the format interface identity is displayed on the screen of the mobile device.
In the example of the present invention, according to the non-linear equation, the current remaining charging time can be displayed accurately. Moreover, the current charging state of the mobile device can be prompted to the user. An alarm clock prompt is performed when the charging procedure ends. If the charging cable is not pulled out after the charging procedure ends, an overcharging prompt is performed. In this way, more charging information is provided, thereby charging the mobile device effectively.
