The present invention relates to a battery temperature notification device and method of a mobile communication terminal, in particular, when the battery temperature is above a predetermined temperature step by step, outputs an alarm sound according to each step and dials to the designated emergency contact point that the battery is hot The present invention relates to a battery temperature notification device and a method of a mobile communication terminal for outputting a voice prompt message.

In general, storage batteries (or rechargeable batteries) have been developed into lead-acid batteries mainly used in automobiles, Ni-cad batteries used in home appliances, nickel-metal hydride batteries, etc. In mobile communication terminals, high efficiency pollution-free lithium ion batteries have been used. Increasingly, companies are using lithium polymer batteries for the safety and compact weight of mobile communication terminals.

The basic principle of the lithium polymer battery is the same as that of the lithium ion battery, but it is more stabilized and has a high energy density by preventing gas and leakage caused by the decomposition of the electrolyte by polymerizing a liquid electrolyte in a polymerized state. .

The charge of the battery can be obtained by adding electrons to the negative electrode of the battery. Usually, a DC component controlled by a constant voltage is applied to charge the electric current by supplying electrons by the difference between the applied voltage and the battery internal voltage.

At this time, the applied voltage per cell (marked as C), which is a nominal unit of the battery, is determined. Normally, a lithium ion battery and a lithium polymer battery for a mobile communication terminal must apply a strictly limited constant voltage of 4.2 V per cell (rated at 3.6 V). . If more than 4.5 is applied per cell, electrolyte is decomposed to generate gas and leakage pressure occurs when the pressure-opening valve is operated, and there is a risk of explosion, and there is a risk of explosion even when the temperature of the battery rises.

Currently, the battery of most mobile communication terminals implements overvoltage, overcurrent, and short circuit protection circuits to prevent explosion or fire. Especially, for overcurrent protection, most of the components are attached to PTC (Positive Thermal Coefficient) Bare cell. However, when the temperature rises, the resistance is increased to cut off the current.), But the situation is insufficient in terms of the explosion protection circuit of the battery due to the high temperature.

However, since there is no protection circuit or preventive technique against battery explosion or fire at high temperatures, if the battery is left at a high temperature, the risk of explosion increases, but there is no secondary preventive measure.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems. When the battery temperature attached to the mobile communication terminal becomes higher than the designated temperature step by step, the alarm sound according to each step is outputted to the designated emergency contact. An object of the present invention is to provide a battery temperature notification device and method for a mobile communication terminal that outputs a voice prompt message indicating that a battery is high by making a phone call.

The present invention for achieving the above object, the temperature averaging unit for detecting the temperature of each part of the surface of the battery through a plurality of temperature detection sensor and outputs the average temperature; A controller for performing a temperature notification operation according to the temperature when the average temperature of the battery is equal to or higher than a specified high temperature; Under the control of the controller, the emergency contact is configured to include an emergency call connection unit for outputting a voice guidance message informing that the battery is high temperature by making a call.

In addition, the present invention comprises the steps of detecting the temperature of each part of the surface of the battery through a plurality of temperature detection sensor and displaying the average temperature on the temperature display at regular intervals; When the battery temperature is above a predetermined temperature step by step, outputting an alarm sound according to each step and calling a designated emergency contact, characterized in that it comprises a step of outputting a voice guidance message indicating that the battery is a high temperature.

The present invention quantifies the temperature measurement of the battery cell using a temperature sensor or other temperature measuring device, and displays the temperature value of each part on the LCD or notified by a user-recognizable method such as an alarm sound, and automatically emergency network The present invention provides a method for allowing a user to prevent battery explosion by informing a battery explosion due to high temperature in advance.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First of all, in adding reference numerals to the components of each drawing, it should be noted that the same components have the same reference numerals as much as possible even if displayed on different drawings.

Also, in the following description, numerous specific details, such as specific processing flows, are set forth in order to provide a more general understanding of the invention, and it is to be understood that the invention may be practiced without these specific details. It will be obvious to them.

In addition, detailed description of well-known functions and structures which are determined to unnecessarily obscure the subject matter of the present invention will be omitted.

1 is a block diagram showing the configuration of a battery temperature automatic notification device of a mobile communication terminal according to the present invention, a plurality of temperature detection sensors (101a ~ 101c) for measuring the temperature of the battery surface by a predetermined portion, and the temperature detection A die conversion unit 102 for quantifying the measured value detected by the sensor, a temperature averaging unit 103 for averaging the temperature of each portion of the die-converted battery surface, and the battery determined by the averaged temperature A control unit 104 for determining whether the surface temperature is equal to or higher than a specified high temperature, and performing a temperature notification operation for each situation; a temperature display unit 105 for changing the color of the LCD or displaying the temperature by numbers under the control of the control unit; A warning sound output unit 106 for generating a warning sound under the control of the control unit and notifying that the temperature is dangerous, and automatically controlling the mobile communication network under the control of the control unit. It is configured to include an emergency call connection 107 for notifying the emergency situation by accessing the emergency contact.

In addition, when the temperature of the battery rises when the power off of the terminal, it further comprises a power switching unit 108 for automatically powering on the terminal.

In this case, the power switching unit 108 does not need to configure a circuit to which a separate driving power is applied, and uses a predetermined temperature element (sensor) that continuously decreases in resistance as the temperature rises. If the temperature is above a predetermined temperature is turned on to power on the terminal.

For reference, Figure 2 is an exemplary view showing the measured temperature for each part of the surface of the battery through the temperature sensor applied to the present invention, wherein the output value of the temperature sensor may be a resistance value or a voltage value depending on the type. .

On the other hand, the temperature display unit 105 displays the temperature on the LCD according to the temperature of the surface of the battery, for example, when the temperature is low, it is displayed in blue as a whole, and the higher the temperature is changed to be closer to red, the menu operation However, it can be displayed as a pale wallpaper so as not to affect the background, and it can be turned into a dark wallpaper at very high temperatures that may explode.

Alternatively, the real-time measured battery surface temperature can be displayed numerically in the information display at the top of the screen (receive sensitivity, battery power, bell type, etc.), depending on your preferences. It is desirable to be able to.

In addition, unlike the temperature display unit displaying the real-time temperature change, the warning sound output unit 106 outputs a warning sound when the battery surface temperature rises above a predetermined temperature, and the temperature is set as a dangerous temperature when the terminal is manufactured by default. It is desirable to allow the user to select a warning sound in the preferences.

In addition, the temperature display unit and the warning sound output unit is a method for notifying the user when the user is near or even if the user is carrying the terminal, but the emergency call connection unit 107 in a place where the situation can not be informed by the alarm sound. If there is a user, call a predetermined emergency contact and output a voice prompt (eg danger of explosion due to high battery temperature). At this time, user can designate emergency contact in environment setting.

3 is a flowchart illustrating a method for automatically notifying a battery temperature of a mobile communication terminal according to the present invention, wherein when the terminal is in an on state, the control unit averages the surface of the battery by the temperature of each part of the battery surface detected from the plurality of temperature detection sensors. The temperature is calculated, the surface temperature is displayed on the LCD screen at regular intervals, and it is determined whether the temperature is higher than the designated high temperature step by step, and only its own alarm sound is output according to each step, or it is automatically connected to the mobile communication network to the designated emergency contact. Notify of emergency.

If the terminal is in the off state, the battery is turned on through the power switching unit when a predetermined temperature or more, and then the surface temperature check process is performed.

As described above, the present invention has a difference in that a high temperature explosion warning sound is automatically transmitted and a system network can be quickly transmitted to prevent an explosion accident caused by a high temperature of a battery without proper measures.
