The present invention relates to a mobile communication terminal and a display method of displaying a battery charging time, in particular, by detecting the current voltage of the battery to calculate the time required to fully charge the battery through the detected voltage, The present invention relates to a mobile communication terminal and a display method of displaying a time required to fully charge a battery so as to greatly improve user convenience by indicating a time value to the outside.

In general, a mobile communication terminal consumes power of a battery installed in the terminal when a user uses the battery for a predetermined time, thereby recharging the discharged battery using an external power source.

In addition, by displaying a bar-shaped battery indicator on the display panel of the terminal, the user can briefly grasp the state of charge / discharge of the battery so that the user can continue to use the terminal.

The battery of the mobile communication terminal performs charging through two processes.

For example, when charging a fully discharged battery, the charger for charging the battery performs a trickle charge for raising the battery voltage above a predetermined value before starting the present charging operation. The trickle charging method is a method of continuously supplying a small current corresponding to 1 to 5% of the charging current used in the present charging operation for about 10 hours. When the method is performed, the charging voltage of the battery is approximately 3.1V. When the remaining voltage of the battery to be charged is greater than or equal to a predetermined voltage, the charging operation is immediately performed.

FIG. 1 is a graph illustrating charging voltage according to time when a battery of a general mobile communication terminal is charged, and is a graph illustrating charging voltage according to time when a residual voltage of the battery is greater than or equal to a predetermined voltage.

That is, when a predetermined voltage or more is reached through the trickle charging, constant current charging is performed to continuously supply a constant current until the battery reaches the target voltage for full charge.

In this case, the target voltage has a voltage value slightly below the voltage supplied by the battery to the mobile communication terminal (usually 4.2V). In the case of a general nickel battery, charging is completed in the constant current charging operation. In the case of a widely used Li-ion battery, the target voltage is reached through constant voltage charge or pulse charge after the target voltage is reached. Allow the battery voltage to reach the full-voltage supply voltage.

However, in the battery of the mobile communication terminal performing the above charging operation, the mobile communication terminal equipped with the battery simply shows the state of charge of the battery through a battery indicator of a bar (bar) simply because the user There is a problem that can not accurately determine the charging progress of the battery.

Therefore, when the battery is used in a state in which it is not fully charged, the battery may be unexpectedly discharged and thus the terminal may not be used.

In addition, since it is not possible to accurately determine the time it takes to fully charge the battery, when the battery needs to be fully charged, it must be waited for the battery to be fully charged. There is a problem that is difficult.

The present invention has been made to solve the above problems of the prior art, and detects the voltage of the battery, and calculates the time required to fully charge the battery through a conversion table that stores each voltage and the corresponding time value It is an object of the present invention to provide a mobile communication terminal and a display method for displaying a battery buffer time required so that the user can accurately determine the time required for the battery buffer by displaying to the outside.

The mobile communication terminal displaying the time required for battery buffer according to the present invention for solving the above problems is mounted on the main body, the battery to charge the external AC power with a DC power supply to the operating power of the main body, and the battery A display unit for displaying the buffering time required according to the charging voltage during charging, and a controller for detecting the remaining voltage of the battery and calculating the time required to reach the buffering voltage, and transferring the calculated required time data to the display unit. Characterized in that it comprises a.

The charger of the mobile communication terminal displaying the time required to fully charge the battery according to the present invention is equipped with a battery that is charged with power to supply operating power, and the battery or the mobile communication terminal in which the battery is coupled to an external power source to the battery. It is characterized in that it comprises a charger main body to be charged, so that the time required to reach the buffer voltage by sensing the voltage of the battery is displayed to the outside.

In addition, the method for displaying the battery buffer time required of the mobile communication terminal according to the present invention is connected to an external power source to start charging the battery, and detects the voltage of the battery to search for a time value corresponding to the detected voltage, And a third step of calculating a time required for the battery to be fully charged based on the retrieved time value, and a third step in which the calculated time value is displayed to the outside.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. First of all, a mobile communication terminal according to the present invention collectively refers to a terminal for transmitting and receiving a plurality of data using a wireless mobile communication network regardless of frequency band, and the battery is not limited to the type of a rechargeable battery such as nickel or lithium ion. Specifies.

2 is an exemplary view illustrating an example of a charging method of a mobile communication terminal according to the present invention, and briefly describes a battery charging method of the mobile communication terminal according to the present invention.

There are two methods for charging a mobile communication terminal according to the present invention. As shown in FIG. 2A, an I / O connector 300 is directly connected to a receptacle 150 of the terminal 100 and charged. And, as shown in Figure 2b, the mobile communication terminal 100 or the battery (B) coupled with the battery (B) is charged in a separate charger 200 connected to the I / O connector 300 is charged Can be distinguished in such a way.

At this time, in the early stages of the spread of mobile communication terminals, the battery terminal arrangement structure was different for each manufacturer, and thus it was not compatible with other chargers of other models and models. .

3 is a block diagram illustrating an internal configuration of a mobile communication terminal according to the present invention.

The mobile communication terminal 100 according to the present invention is a battery (B) for supplying the operating power to the terminal 100 when the external AC power is charged to the DC power supply to the terminal 100 and the battery (B) Control unit 120 for calculating the time required to fully charge the battery (B) and the time required to fully charge the battery (B) when the charging time according to the charging voltage is displayed on the display unit 110 It is configured to include).

In addition, when the operating power is applied from the battery (B), the main control unit 121 for controlling the operation of each unit and the control program for controlling the operation of the main control unit 121 or user data input from the outside It is configured to include a memory unit 122 to be stored.

At this time, the battery indicator indicating the residual voltage according to the charge / discharge of the battery through the display unit 110 is implemented in the form of a bar (bar) to determine the residual voltage according to the number of bars (bar).

The controller 120 detects the remaining voltage of the battery when the battery mounted in the terminal is connected to an external power source for charging and calculates the time required to reach the buffer state.

Therefore, the control unit 120 is connected to an external power source for charging the battery, the charge connection detection unit 123 for detecting this, and when the detection signal is transmitted from the charge connection detection unit 123, the residual voltage of the battery It is configured to include a charge control unit 130 to calculate the time required to reach the buffer voltage by measuring the.

The charging control unit 130 may calculate the required time until the buffering through a conversion table corresponding to each specific voltage and time value, and for this purpose, an external power source from the charging connection detecting unit 123 may be used.

Thus, as the time values for charging the respective voltages correspond to each other, as the voltage is subdivided into a plurality of stages, the buffering time data can be more accurately calculated.

The conversion table data may be configured as shown in the following table, for example.

T_memory Time Voltage V_memory 0 00:00:00 0.006 0 One 00:00:25 0.005 One 2 00:00:45 3.072 2 3 00:01:00 3.156 3 4 00:02:00 3.277 4 5 00:03:00 3.359 5 6 00:04:00 3.509 6 7 00:05:00 3.581 7 8 00:06:00 3.639 8 9 00:07:00 3.681 9 10 00:08:00 3.706 10 11 00:09:00 3.729 11 12 00:10:00 3.747 12 13 00:20:00 3.860 13 14 00:30:00 3.902 14 15 00:40:00 3.927 15 16 00:50:00 3.395 16 17 01:00:00 3.986 17 18 01:10:00 4.037 18 19 01:20:00 4.091 19 20 01:30:00 4.192 20 21 01:40:00 4.256 21 22 01:50:00 4.230 22 23 02:00:00 4.210 23 24 02:00:25 4.209 24

Accordingly, when the required voltage calculation unit 132 has a buffer voltage of 4.2 V and the detected residual voltage of the battery is 3.706 V, the required time calculating unit 132 has a time corresponding to the buffer voltage of 2 hours and 25 seconds according to the table. 1 hour 52 minutes 25 seconds, which is a difference of 8 minutes corresponding to the residual voltage, is calculated, and the calculated time value becomes time data required for buffering.
