The present invention will be further described below in conjunction with accompanying drawing and embodiment, in the accompanying drawing:

Fig. 1 is a flow chart of a mobile terminal battery charging state reminder method in a preferred embodiment of the present invention;

Fig. 2 is a functional block diagram of a mobile terminal battery charging state reminding device according to a preferred embodiment of the present invention.

Detailed ways

The flow of the method for reminding the charging state of the mobile terminal battery in a preferred embodiment of the present invention is shown in Figure 1. The method runs on the mobile terminal and specifically includes the following steps: S1. Detect whether the charging interface is connected to the power supply, and if so, enter the charging mode Charge the battery; S2. In the charging mode, calculate the remaining charging time of the battery and display it; S3. Determine whether the battery is fully charged; S4. If it is fully charged, display the end of charging; otherwise, execute step S2. When the mobile terminal user charges the battery, he can know whether it is fully charged through the displayed charging status at any time, and when it is not fully charged, he can always know how long it will take to fully charge. In this way, the user can reasonably arrange time to charge the mobile terminal, and try to ensure that there is enough time to fully charge the battery every time, so as to prolong the service life of the battery and improve user experience.

In the methods of the above embodiments, various methods can be used to calculate the remaining charging time of the battery. For example, for a nickel-cadmium battery or a nickel-hydrogen battery, the remaining charging time of the battery can be calculated by detecting parameters such as battery voltage and temperature.

Preferably, in the above embodiments, the method for calculating the remaining charging time is to calculate the remaining charging time according to the remaining battery capacity and the current charging current. At present, the battery capacity of mobile terminals such as mobile phones is expressed in mAh (milliampere hours); wherein, mA represents the magnitude of the current, and h represents the time. For example: the battery capacity can be 1500mAh, 2000mAh, etc. When charging, the full charging time can be calculated according to the current charging current. Take a battery with a capacity of 1500mAh as an example, if the current charging current is 150mA, then the total time to fully charge the battery is: 1500mAh/150mA=10h (10 hours).

Specifically, the above step S2 specifically includes: S21. Calculate the remaining battery capacity, wherein, the remaining battery capacity=total battery capacity-total battery capacity×(current supply voltage of the battery/supply voltage when the battery is fully charged); S22. Calculate the remaining charging time, Among them, the remaining charging time = remaining battery capacity / charging current. For example, for a battery with a capacity of 1500mAh, when it is fully charged, the power supply voltage is 5V. When the current power supply voltage of the battery is 4V, the current battery capacity can be calculated as: 1500mAh*4/5=1200mAh; the remaining battery capacity of the battery is : 1500mAh－1200mAh=300mAh; remaining charging time: 300mAh/150mAh=2h (2 hours).

Further, in the above method, step S2 further includes displaying the percentage of the current battery capacity while displaying the remaining charging time. The user can know the current battery capacity while seeing the remaining charging time. If the user thinks that the current battery capacity is sufficient, the user can unplug the mobile terminal from the power source and stop charging, which further improves the user experience.

In another embodiment of the present invention, there is also provided a mobile terminal battery charging state reminding device, as shown in FIG. Among them, the detection module 10 is used to detect whether the charging interface is connected to the power supply, and if so, enters the charging mode to charge the battery; the calculation module 20 is used to calculate the remaining charging time of the battery in the charging mode; the judgment module 30 is used for Determine whether the battery is fully charged, if fully charged, then start the display module to display the end of charging, otherwise start the calculation module to recalculate the current remaining charging time; the display module 40 is used to display the remaining charging time and whether the charging is over. When the mobile terminal user charges the battery, he can know whether it is fully charged through the displayed charging status at any time, and when it is not fully charged, he can always know how long it will take to fully charge. In this way, the user can reasonably arrange time to charge the mobile terminal, and try to ensure that there is enough time to fully charge the battery every time, so as to prolong the service life of the battery and improve user experience.

Similarly, in the device of the above-mentioned embodiment, the calculation module 20 can use various methods to calculate the remaining charging time of the battery, for example: for a nickel-cadmium battery or a nickel-metal hydride battery, the remaining charging time of the battery can be calculated by detecting parameters such as battery voltage and temperature .

Preferably, in the calculation module 20 described above, the method for calculating the remaining charging time is to calculate the remaining charging time according to the remaining battery capacity and the current charging current. At present, the battery capacity of mobile terminals such as mobile phones is expressed in mAh (milliampere hours); wherein, mA represents the magnitude of the current, and h represents the time. For example: the battery capacity can be 1500mAh, 2000mAh, etc. When charging, the full charging time can be calculated according to the current charging current. Taking a battery with a capacity of 2000mAh as an example, if the current charging current is 100mA, then the total time to fully charge the battery is: 2000mAh/100mA=20h (20 hours).

Furthermore, as shown in FIG. 2 , the calculation module 20 includes: a remaining battery capacity calculation unit 21 for calculating the remaining battery capacity, wherein, the remaining battery capacity=total battery capacity−total battery capacity×(current supply voltage of the battery/ The power supply voltage when the battery is fully charged); the remaining charging time calculation unit 22 is used to calculate the remaining charging time, wherein the remaining charging time=remaining battery capacity/charging current.

For example, for a battery with a capacity of 2000mAh, when it is fully charged, the power supply voltage is 5V. When the current power supply voltage of the battery is 4V, the current power of the battery can be calculated as: 2000mAh*4/5=1600mAh; the remaining battery capacity of the battery is : 2000mAh－1600mAh=400mAh; remaining charging time: 400mAh/100mAh=4h (4 hours).

Further, the display module 40 in the above device is also used to display the percentage of the current battery capacity while displaying the remaining charging time. Therefore, the user can know the current battery capacity while seeing the remaining charging time. If the user thinks that the current battery capacity is sufficient, the user can unplug the mobile terminal from the power source and stop charging, thereby further improving the user experience.

In another embodiment of the present invention, a mobile terminal is also provided, which includes the device for reminding the charging state of the mobile terminal battery according to any one of the foregoing items. For specific principles, please refer to the foregoing embodiments, which will not be repeated here.

To sum up, the present invention calculates and displays the remaining charging time of the battery of the mobile terminal, so that the user can intuitively see the current charging state of the battery, so as to arrange the time reasonably and improve the user experience.
