FIG. 3 is a flowchart of a method for acquiring a charging parameter according to an embodiment of the present invention. As shown in FIG. 2, the method in this embodiment includes the following steps:

S10, in the process of charging the battery by the mobile terminal, periodically sampling the voltage value of the battery, recording the charging duration corresponding to each sample point and the voltage value obtained by the sampling;

S20. Store the correspondence between the charging duration and the voltage value in the mobile terminal. In a preferred embodiment, in step S10, the process of charging the battery by the mobile terminal may be a charging test process performed by the mobile terminal on the battery before leaving the factory; in step S20, the correspondence between the charging duration and the voltage value, It can be recorded during the one-time charge test, or it is the charge duration and voltage value recorded during the multiple charge test process. Obtained after curve fitting. In a preferred embodiment, in step S10, the process of charging the battery by the mobile terminal may also be a process in which the mobile terminal self-learning to obtain the corresponding relationship after leaving the factory. During the process of acquiring the corresponding relationship by the mobile terminal by self-learning, if the battery is full, the recording self-learning has been completed, the battery is not full, the recording self-learning has not been completed; and the mobile terminal is again facing the battery. During charging, if it is determined that the self-learning has been completed, the mobile terminal samples the voltage value of the battery, and calculates the remaining charging time according to the corresponding relationship; if it is determined that the self-learning has not been completed, the self-learning is started again to obtain the corresponding The process of relationship.

When the mobile terminal samples the voltage value of the battery, if the voltage value of the sample is not queried from the correspondence, the voltage value of the sample is recorded and the charging time corresponding to the current charging process is recorded. Until the voltage value of the sample is equal to the minimum voltage value recorded in the correspondence relationship; the charging duration recorded in the correspondence relationship is respectively added to the charging duration up to the minimum voltage value in the current charging process And then update the corresponding relationship. The method for displaying the remaining charging duration proposed by the embodiment of the present invention will be described in detail below with two application examples. Application Example 1 Before the mobile terminal leaves the factory, test the battery of the model of the mobile terminal. For example, when the voltage value is 0, the battery is charged, the voltage value is sampled, and the voltage value of the sample is recorded and corresponding. The charging duration, such as the tv correspondence value, is fitted into a storage unit of the mobile terminal (for example, flash (flash)) after multiple tests, and the test can use a certain high frequency test method to Ensure that the fitted curve is accurate enough. As shown in FIG. 4, the application example includes the following steps: Step 101: The mobile terminal periodically samples the current voltage value of the battery during charging; Step 102: Find the charging time corresponding to the voltage value of the sample in the tV curve value. Since the tv curve value stored in a certain interval during the learning process is a discrete value, the current voltage value obtained by the sample can be set to a matching range and then matched in the flash, as long as the flash exists in the matching range. Value, you can think that the match is successful. Step 103: Read the total duration t _n when the battery is full from the tV curve value, calculate the remaining charging time to, to=t _n - ti; Step 104, read the remaining charging time t. , display it on the screen. Of course, in step 101, during the charging process, the mobile terminal may also start the current voltage value of the sampling battery after receiving the instruction input by the user to display the remaining charging duration when the user queries through the menu.

The advantage of this application example is that the battery is tested repeatedly before leaving the factory, the sample frequency is high, and the t-v fitting schedule is more accurate, so that the remaining time displayed is more accurate.

Application Example 2 The correspondence between the voltage value of the battery of the mobile terminal and the charging duration in the application example is obtained by self-learning during the charging process. As shown in FIG. 5, the following steps are included: Step 201: The mobile terminal starts charging. Step 202: Determine whether the last charge self-learning is completed. If not, go to step 203. If yes, go to step 204. In this embodiment, the default value of the preset charge status flag (flag) is 0. The default self-learning is not completed, if flag=l indicates that self-learning has been completed. Step 203: Perform a charging self-learning process. In general, charging self-learning occurs when the first charge or the user's last charge does not fully charge the battery. Step 204: A pop-up prompt box prompts whether re-learning is needed. If the user chooses to learn, then the process proceeds to step 203. If the user chooses not to learn, then the process proceeds to step 205. In general, after replacing another type of battery or The use of the battery, you need to relearn when the battery charging time changes.

Step 205: Acquire a remaining charging duration according to the correspondence between the voltage value of the existing battery and the charging duration, and display the remaining charging duration. The advantage of this application example is that it does not require the battery to be tested before leaving the factory and can be adapted to electricity. In any state of the pool, the remaining time of charging can be displayed. The increased self-learning link can automatically record the tV curve value. After replacing the battery, the tV curve value can be re-learned and updated, the adaptive ability is stronger, and the remaining time is also accurate. . 6 is a charging self-learning flowchart of the application example, and includes the following steps: Step 301: First, the saved tv curve value in the storage unit is cleared. Step 302: Timing the voltage of the sample battery, recording the voltage value of the sample and the charging time corresponding to the current charging process. Step 303: Determine whether the battery is full, that is, determine whether the voltage of the battery has reached the highest value, for example, 4.2 V. If full, go to step 304; if not, go to step 305. Step 304: Stop the sampling, set the charging flag flag to 1 to identify that the self-learning process is completed. Step 305: Set the charging flag flag to 0, indicating that the self-learning process is not completed. The primary role of this self-learning process is to adaptively record and learn new battery tV curve values. Provides queryable data for the next charge acquisition and display of the remaining time, thus ensuring that the remaining time of charging is correctly displayed.

Figure 7 is a flow chart showing the remaining charging duration for the application example. The steps are as follows: Step 401: During the charging process, the current voltage value of the battery is timed. Step 402: Determine whether the current voltage value can be found on the existing tV curve relationship. If not, go to step 403. If found, go to step 404. When the user last charged, it may not be Charging starts from zero charge, resulting in the origin of coordinates

(ie, at time 0 in the tV curve relationship) the corresponding voltage value is not zero. 4叚Set the 0 time corresponding voltage value is 2V, then the voltage value of 0V ~ 2V is not recorded, and the tV curve value is not perfect. In the case where the voltage value of the sample is in the range of 0V to 2V, it is necessary to first complete the tV curve and then obtain the remaining charging time. Step 403: If it is found that the voltage value is not found, that is, the current voltage value is smaller than the voltage value corresponding to the 0 point in the tv curve, the voltage value of the sample and its charge during the charging process are recorded in the storage unit. The electrical duration, until the voltage value of the sample can be found on the curve, that is, the minimum voltage value in the tV curve is reached, and the tv curve value is updated in time. The update method of this application example may be that the charging durations of the records in the original tv curve relationship are respectively added, and the charging time portion when the minimum voltage value in the tv curve is sampled during the charging process, The tV coordinates can be updated by corresponding translation. Then, the time length corresponding to the current voltage value and the total duration t _n are read in the updated tV curve value, and the process proceeds to step 405. Step 404: Read the time corresponding to the current voltage value and the total time t _n in the tV curve value, and then go to step 405. Step 405: Calculate the remaining charging time period t ₀ := ^. Step 406: Display the remaining time to to display on the screen. This application example considers that when the user does not charge from zero power, the tV curve value is updated by updating, and the correct remaining charging time is adaptively displayed.
