Description

[0001] MOBILE TERMINAL WITH MULTI BATTERY [0002]

The present invention relates to a mobile terminal having at least two batteries.

A mobile terminal such as a cellular phone is intended for portability and uses a battery as a power supply means. Generally, a mobile terminal uses a self-designed battery cell to satisfy voltage and current characteristics suitable for each product, and a rechargeable secondary battery is supplied together with the product for reuse by users. The secondary batteries supplied with the current products include lithium ion batteries, nickel-cadmium batteries, and nickel-hydrogen batteries.

As technology develops, battery cells provided with mobile terminals are also developing. For example, the battery cell usage time is gradually increasing, the size of the battery cell is getting smaller, and the weight is also decreasing. However, even if the battery cell is developed, the use time is limited.

25 is a rear view showing a conventional mobile terminal.

Referring to FIG. 25, a conventional mobile terminal includes a battery cell 15 mounted on a rear portion thereof. There is only one mounting portion capable of accommodating the battery cell 15 in the conventional mobile terminal body 10 and the battery cell 15 is connected to the mobile terminal body 10 As shown in Fig.

The mobile terminal body 10 and the battery cell 15 are connected to each other by a power terminal that is in electrical contact with each other and power terminal terminals where the mobile terminal body 10 and the battery cell 15 are contacted with each other The power of the mobile terminal is turned off.

As described above, the amount of power supplied to the battery cell 15 is limited, and even when the mobile terminal is in use, the use of the mobile terminal often has to be stopped due to exhaustion of the battery cell 15.

In some cases, the auxiliary battery cells may be carried together to replace the battery cells. However, in the process of replacing the battery cells, the power terminals are inevitably separated from each other and the power of the mobile terminal can not be turned off . Therefore, when the battery cell 15 is exhausted, important telephone calls must be stopped. Fortunately, even if there is the auxiliary battery, it is troublesome to re-call after replacing the battery.

In addition, in the case of receiving a wireless data service using a mobile terminal, all operations in progress due to exhaustion of the battery cell can be canceled, and it is troublesome to reconnect to the wireless data service after the replacement of the battery cell and re- have.

Also, in the case of receiving a large amount of data by using the mobile terminal, the downloading should be stopped due to the exhaustion of the battery cell, and the user must experience a time and economic loss when it is impossible to receive the file that is being downloaded.

It is an object of the present invention to provide a mobile terminal in which a user can conveniently use multiple batteries.

Another aspect of the present invention is to provide a mobile terminal in which a user can conveniently check the operation state of the multiple batteries in a mobile terminal having multiple batteries.

According to an aspect of the present invention, there is provided a mobile terminal including a first battery and a second battery that supply driving power to components of a mobile terminal; An output unit for outputting (e.g., displaying) the internal state of the mobile terminal to the user; And a controller for notifying a user of a state of charge of the first battery and the second battery.

According to another aspect of the present invention, there is provided a mobile terminal including: a first battery and a second battery that supply driving power of components of the mobile terminal; An output unit for outputting (e.g., displaying) the inquiry to the user; A user input unit receiving a user's instruction; And a control unit for inquiring of the user about the charging of the first battery and the second battery, and performing charging between the first and second batteries by receiving an instruction thereto.

According to the present invention, there is an advantage that the user can easily check the operation status of the multiple batteries included in the mobile terminal.

Alternatively, the present invention has an advantage that a user can conveniently use multiple batteries provided in the mobile terminal.

Alternatively, even if the amount of one battery is insufficient, the present invention is advantageous in that the user can normally carry out calls, multimedia reproduction, and wireless data services performed by the other battery.

Before describing the present invention, the mode of use of the mobile terminal according to the present invention will be described below.

The mobile terminal according to the present invention can operate in the "normal mode" and the "power saving mode" as in a general mobile terminal. The "normal mode" is a usage mode optimized to fully exercise the functions of the mobile terminal. The mobile terminal of the "normal mode" keeps the display brightness that the user is comfortable to recognize, and immediately switches the HW / SW modules for the additional function according to the user's instruction so as to perform additional functions such as Bluetooth, It is ready to run.

The mobile terminal in the "power saving mode" is in a state where it can perform almost all the functions of the mobile terminal, but the power of the mobile terminal can be reduced by reducing the brightness of the display consuming a large amount of power, It is driven in a way to reduce consumption.

In the meantime, the "emergency mode" presented in the present invention is an operation mode of the mobile terminal proposed for an emergency situation in which the charging level of the battery is low, but an urgent call is to be performed.

The mobile terminal in the "emergency mode " activates only the fundamental functions of the mobile terminal and deactivates the remaining additional functions. For example, the mobile terminal for cellular wireless communication in the "emergency mode " can deactivate other functions except for the voice communication function and the text message transmission / reception function. In addition, the distinction between the activation function and the inactivation function of the "emergency mode" may vary depending on the implementation and may be actively set by the user.

In the following description of the present invention, "idle screen " means a screen displayed on a display in a state where a mobile communication terminal for wireless communication does not perform a call and is in a standby state for a call. For power saving, if there is no manipulation of the user for a certain period of time, the "idle screen" is terminated, but may be output again by key input of the user.
