The present invention is to accurately detect and display the battery remaining capacity of the mobile terminal, in particular, divided into the standby state and the operating state, the standby state is the ratio of the voltage, the operating state is detected the current consumed by the ratio of the current The present invention relates to a battery remaining amount display device and a method of a mobile terminal for accurately displaying the remaining battery level.

The mobile terminal (UE: USER EQUIPMENT) monitors the mobile switching center (MSC: MOBILE SWITCHING CENTER) freely moving in the service area formed by the corresponding base station (RAN: RADIO ACCESS NETWORK) of the registered mobile communication system. It is a high-tech wireless communication device that allows an individual to carry it anywhere and always carry it directly by wireless connection and communication with the desired party anytime and anywhere through the communication path established by the control and switching.

Since the portable terminal operates while moving, and commercial power cannot be used as an operating power source, the portable terminal uses power supplied from a battery having a structure that can be easily removed and replaced.

The mobile terminal (UE) is analyzed to spend less of the time to carry out the actual communication and the actual communication, and to increase the low utilization rate as described above, and increase the applicability and convenience of real life using the mobile terminal At the same time, various additional services have been developed and provided to promote the use of communication.

The additional services are largely developed and provided by a mobile communication service provider and developed by a producer and provided in a built-in state in a portable terminal.

Additional services developed and provided by the manufacturers include cameras, Bluetooth, wireless LAN, radios, games, electronic calculators, calendars, clocks, ringtone settings, and the like. Messages, video messages, online games, wireless Internet access, and the like, and these additional services continue to be developed with new features.

As described above, the mobile terminal is not only used for mobile communication, but also various video services can be used to shoot video signals using a camera function, access the Internet wirelessly, perform short-range data communication using a wireless LAN, or play online games. Or listening to music using the MP3 or radio function, there is a problem that the consumption of operating power increases.

The portable terminal should be small in size and weight for convenience of portability and movement, and the battery supplying the operating power can supply more operating power as the size is larger, but it is not limited indefinitely.

In addition, multimedia communication, game, video message transmission, etc. using the video signal is a lot of power consumption, there is a problem that is interrupted due to lack of power during the communication.

In addition, the voltage level output from the battery is measured by the voltage drop based on the internal resistance of the battery and the internal resistance value of the load, and when the amount of current consumed by the load is large, there is a problem such that the width of the voltage drop temporarily increases. .

Accordingly, there is a need to develop a technology for accurately identifying and displaying the current remaining capacity of a battery that supplies an operating power source.

Hereinafter, according to the prior art, the battery remaining amount display method of the portable terminal will be described with reference to the accompanying drawings.

Attached to explain the prior art, FIG. 1 is a functional configuration diagram of a battery remaining amount display device of a portable terminal according to the prior art, and FIG.

Referring to FIG. 1, the battery remaining amount display device of the conventional mobile terminal is described by discharging and supplying charged power. 20) is supplied with operating power.

The load 20 is a main body of a mobile terminal for mobile communication, and receives operating power from the battery 10 by a power switch (SWITCH) operation not shown in detail in the drawing. It includes various functions such as Bluetooth function and game function.

The battery 10 is simply a power supply, also called a dumb battery, and repeats a process of supplying current stored by charging and discharging. Use batteries again and again.

In general, the battery 10 has a maximum voltage normally output in a fully charged state of about 4.2 volts (V), and a voltage decreases as discharge current is discharged, and below about 3.2 volts (V), a breakdown phenomenon of the battery, That is, the destruction phenomenon that cannot be recharged occurs.

The 3.2V is referred to as a cut-off voltage, and the switch is controlled by sensing that the voltage falls below the cut-off voltage, thereby preventing further current from being discharged from the battery 10.

By detecting the battery voltage as described above, there is an edit unit 30, the edit unit 30 detects the analog (ANALOG) state voltage of the battery 10, converts to a digital state voltage and outputs As described above, the digital voltage is applied to the controller 40.

The controller 40 analyzes the voltage of the battery 10 detected by the edit unit 30 and displays the remaining amount of the current battery in a bar graph based on a corresponding criterion.

In the battery residual amount display method by the controller 40, when the battery output voltage or the internal voltage is detected at 4.2 volts in a fully charged state, a 100% bar graph is displayed through the corresponding display unit (not shown). If a 3.2 volt voltage is detected in the cutoff state, a 0% bar graph is displayed.

In addition, when a voltage below the cutoff state is detected, the output of the operating power is automatically cut off to protect the battery 10.

Each of the battery 10 and the load 20 has a corresponding internal resistance, and when current consumption increases in the load 20, the battery 10 instantaneously increases due to a large amount of current discharge. The cutoff voltage is brought to a state.

When the cutoff voltage is lower than the cutoff voltage, the control unit 40 detects the cutoff unit 30 through the edit unit 30, and the control unit 40 controls the control switch to protect the battery 10. Therefore, the battery 10 may not supply the operating power to the load 20.

That is, in a state in which power that can be supplied to the battery 10 still remains, a cut-off voltage is generated in the battery 10 due to instantaneous overcurrent consumption of the load 20, and the controller 40 By cutting off the operating power output from the battery by detecting the cutoff voltage of), the supply of the operating power to the load is interrupted, which causes a problem of shaking of the battery voltage.

Hereinafter, a method of displaying a battery remaining amount of a portable terminal according to the related art will be described with reference to FIG. 2.

The control unit 40 of the mobile communication terminal determines whether to supply operating power to each functional unit from the battery 10 (S10), and measures the battery voltage when supplying the operating power in the determination (S10). (S20).

The control unit 40 converts the measured battery 10 voltage into a percentage value (%) between the full charge state voltage and the cut-off voltage of the battery 10 (S30), and as a bar graph. It converts it to be displayed, outputs it to the corresponding display part, and displays it as a bar graph.

As described above, the battery level display method according to the related art is a method of directly measuring a voltage level of a battery and displaying it by a percentage between a full charge state voltage and a cutoff state voltage. When a state occurs, a shaking phenomenon occurs that cuts off the supply of operating power while the capacity of the battery remains, and thus there is a problem of interrupting communication in progress.

The present invention displays the remaining amount by measuring the battery current consumption in the operating state of the mobile terminal, and displays the remaining amount by measuring the internal voltage of the battery in the standby state, so the remaining battery table of the mobile terminal accurately detects and displays the remaining battery without shaking The purpose is to provide market values and methods.
