Description

Mobile terminal with multiple batteries {MOBILE TERMINAL WITH MULTI BATTERY}

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

A mobile terminal such as a mobile phone is intended for portability and uses a battery as a power supply means. In general, a mobile terminal uses a battery cell designed in order to satisfy voltage and current characteristics suitable for each product, and supplies a rechargeable battery with a product for user reuse. Secondary batteries supplied with the current products include lithium ion batteries, nickel-cadmium batteries, and nickel-hydrogen batteries.

As the technology evolves, the battery cells provided with the mobile terminal are also evolving. For example, the usage time of a battery cell is gradually increasing, the size of the battery cell is getting smaller, and the weight is also decreasing. However, there is a problem that the use time is finite even when the battery cell is generated.

25 is a rear view of a conventional mobile terminal.

Referring to FIG. 25, a conventional mobile terminal includes a battery cell 15 mounted at a rear side thereof. In the conventional mobile terminal main body 10, there is only one mounting unit capable of accommodating the battery cell 15, and moves the battery cell 15 to the mobile terminal main body 10 by moving the binding piece located at the top of the battery cell 15. Can be mounted or removed.

The mobile terminal body 10 and the battery cell 15 are connected by power terminals which are in electrical contact with each other. The mobile terminal is turned off.

As mentioned above, the amount of power supplied to the battery cell 15 is limited, and there are many cases in which the use of the mobile terminal must be stopped due to the exhaustion of the battery cell 15 even while the mobile terminal is being used.

In some cases, the battery cells may be replaced by carrying the auxiliary battery cells together, but the power terminals may be separated from each other in the process of replacing the battery cells, and the power of the mobile terminal cannot be turned off. . Therefore, when the battery cell 15 is exhausted, important phone calls must be stopped, and fortunately, even if there is a spare battery, there is a hassle of having to try to re-call after replacing the battery.

In addition, when receiving a wireless data service using a mobile terminal, all the work in progress due to the exhaustion of the battery cell may be canceled, and the trouble of having to reconnect to the wireless data service and re-enter the menu after replacing the battery cell. have.

In addition, even in the case of receiving a large amount of data using a mobile terminal, the download must be stopped due to exhaustion of the battery cell, and if the download of the file being downloaded is impossible, the user must suffer time and economic loss.

An object of the present invention is to provide a mobile terminal that a user can conveniently use multiple batteries.

Another object of the present invention is to provide a mobile terminal in which a user can easily check an operation state of the multiple battery in a mobile terminal having multiple batteries.

A mobile terminal according to an embodiment of the present invention, the first battery and the second battery for supplying the driving power of the components of the mobile terminal; An output unit configured to output (eg, display) an internal state of the mobile terminal to a user; And a controller for notifying a user of the state of charge of the first battery and the second battery.

A mobile terminal according to another embodiment of the present invention, the first battery and the second battery for supplying the driving power of the components of the mobile terminal; An output unit for outputting an inquiry content (eg, a display) to a user; A user input unit receiving a user's instruction; And a controller for inquiring a user about charging between the first battery and the second battery, and receiving an instruction for performing the charging between the first battery and the second battery.

By implementing the mobile terminal of the present invention according to the above configuration, there is an advantage that the user can easily check the operation state of the multi-battery provided in the mobile terminal.

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

In another aspect, the present invention has an advantage in that a call, a multimedia play, a wireless data service, etc., performed by a user using a different battery, can be normally performed even if the amount of charge of one battery is insufficient.

Hereinafter, prior to describing the present invention, a usage mode of a mobile terminal according to the spirit of the present invention will be defined.

The mobile terminal according to the spirit of the present invention may operate in the "normal mode" and the "sleep mode" as in the case of the general mobile terminal. The "normal mode" is a usage mode that is optimized to fully exhibit the functions of the mobile terminal. The mobile terminal in the "normal mode" maintains display brightness that is easy for the user to recognize, and directly performs HW / SW modules for additional functions according to the user's instructions so that the user can perform additional functions such as Bluetooth, mp3 player, and DMB. It's in a runnable state.

The mobile terminal of the "sleep mode" is in a state capable of performing almost all functions of the mobile terminal, but lowers the brightness of the power-consuming display and sets the display to turn off after a predetermined time. It is driven in a way to reduce the consumption.

On the other hand, the "emergency mode" proposed in the present invention is a mode of operation of a mobile terminal proposed for an emergency situation in which the battery charge level is low, but an urgent call should be performed.

The mobile terminal in the "emergency mode" activates only the essential functions of the mobile terminal and deactivates the remaining additional functions. For example, the mobile terminal for cellular wireless communication in the "emergency mode" may deactivate all functions except for a voice call function and a text message transmission / reception function. In addition, the division of the activation function and the deactivation function of the "emergency mode" may vary depending on the implementation and may be actively set by the user.

Meanwhile, in the description of the present invention, "child screen" refers to a screen that is output on a display in a state of waiting for a call without performing a call in the mobile terminal for wireless communication. For power saving, if there is no user's operation for a certain time, the "idle screen" is terminated, but can be output again by the user's key input.
