The present invention relates to a personal portable terminal, a charger for a personal portable terminal and a charging method of a personal portable terminal, and more particularly, a portable terminal and a charger for charging a battery of the device and various terminal devices that can be used without restrictions in place. It relates to a charging method of the device.

The personal portable terminal widely used herein is a portable electric and electronic device such as a PDA (Personal Digital Assistant), a smart phone, a handheld PC, a mobile phone, an MP3 player, and the like, and code division multiplexing. Access) module, Bluetooth module, infrared communication module (IrDA), can be provided with a predetermined communication module, such as wired and wireless LAN card, and is equipped with a predetermined microprocessor that performs a multimedia playback function collectively referred to a terminal having a predetermined computing power It is a concept.

Since a personal portable terminal has a main purpose of carrying it, it is essential to charge a battery unit which transmits power to the personal portable terminal. Therefore, the battery charging device is an important element of the personal portable terminal.

1 is a block diagram of a battery charger of a conventional personal portable terminal.

Referring to FIG. 1, a current controller 20 for controlling a current by receiving an external charging power source 10, a current detector 30 for sensing a current applied from the current controller 20, and the current detector A battery pack provided with a voltage protection unit 40 for sensing a voltage applied from the 30 and a battery protection circuit 51 and a battery cell 52 which are charged using a current applied from the voltage detection unit 40 ( 50 and a controller 60 which receives the current and voltage sensed by the current and voltage detectors 30 and 40 and controls the constant voltage charge after the constant current charge through the control of the current controller 20.

The battery protection circuit 51 is a circuit that protects the battery cell 52 from an overcurrent voltage applied in series with the battery cell 52.

Referring to the accompanying drawings, a battery charging apparatus for a conventional personal portable terminal configured as described above is as follows.

First, the current controller 20 receives an external charging power source 10 to control a current supply according to a control signal of the controller 60, and the current detector 30 receives a current applied from the current controller 20. Detects the signal and outputs it to the input terminal ADC1 of the controller 60. In addition, the voltage detector 40 detects a power supply voltage applied from the current detector 30 and outputs the voltage to the input terminal ADC2 of the controller 60.

The current voltage applied from the voltage sensing unit 40 passes through the battery protection circuit 51 inside the battery pack 50 and then is charged in the battery cell 52. Here, the battery cell 52 uses a lithium ion battery (Li -Ion Battery).

 The charging of the battery cells 52 is performed through the constant voltage charging mode after performing the constant current charging board. The controller 60 senses the battery voltage input to the input terminal ADC2 and the constant current when the voltage is low. The current control signal is output to the current control unit 20 so as to be charged so that a constant amount of current is supplied to the battery.

When the battery charging voltage is detected as the constant voltage V0 while charging in the constant current charging mode, the battery is switched to the constant voltage charging mode to perform charging. To this end, the controller 60 detects the charging voltage input from the voltage detector 40 to the input terminal ADC2 for the constant voltage charging board and outputs a voltage control signal to the current controller 30 to output the battery cell 52. Ensure that a constant voltage is supplied to the

Thereafter, when the voltage sensed by the current detector 40 is lower than or equal to the set voltage, the battery 52 is fully charged. At this time, the controller 60 controls the current controller 20 to cut off the current supply.

However, if the personal portable terminal is charged using the battery charger, the personal portable terminal does not operate during charging. Therefore, there is a disadvantage in that the function of the personal portable terminal cannot be used separately during charging. For example, when charging a personal portable terminal, it is usually charged in a prominent place. Therefore, most of these places are provided with necessary information by arranging a calendar or a clock. In this case, when the personal portable terminal is connected to the charging device, the charging device acts as a holder, so that the personal portable terminal is easily seen by the user. Therefore, the personal portable terminal can be used in place of the above functions, and the necessary information can be easily obtained. However, in the conventional personal portable terminal, such a function does not work while charging.

The control unit operates the time display module in response to the charging signal detected from the charging detection module. Therefore, when the battery charge from the external power source is detected, the time is displayed through the display unit.

In addition, in the personal portable terminal, the charging detection module may include a first recognition terminal, and the first recognition terminal may be exposed to the outside of the terminal body to correspond to the second recognition terminal of the external charger.

The conventional personal portable terminal does not operate a separate function during charging. However, the personal portable terminal according to the present invention includes a charge sensing module and a time display module, and when the charge of the personal portable terminal is detected, the time is displayed on the display unit. Therefore, the user can be placed in a prominent place such as a desk or side table to check the time while charging the personal mobile terminal is useful, it is economical because you do not need to purchase a separate watch. However, in another embodiment of the present invention, various information such as a calendar or remaining time of charging may be displayed on the display unit according to a designer's intention.

Further, according to another preferred embodiment of the present invention for achieving the above object of the present invention, the charger has a charger body, a power supply module and a second recognition terminal.
