Description

[0001] CONTROLLER FOR OUTPUT CHARGING STATE [

The present invention relates to a charge remaining amount display controller.

Recently, the use of smart terminals has been popularized due to the increase in the spread of smart terminals. However, the battery life is rapidly shortened due to misuse and overcharging of the battery, and the manufacturer and the sales company suffer damage There are many.

At this time, a method of preventing overcharge of the battery is performed by separating the battery and the charging device when the charging is completed. In this connection, in Korean Patent Laid-Open Publication No. 2007-0047952 (published on May 05, 2007), a battery is mounted in a slot and fixed to a locker, and when the charging is completed, the locker is bent by the magnetic force of the electromagnet Thereby releasing the engagement.

However, before charging is completed, the user can not confirm how much the battery has been charged, so it is not possible to completely determine whether the battery should be taken out or continuously charged when going out, and how long the battery should be charged I can not judge at all. To do this, the battery must be re-mounted in the mobile terminal and the charge level checked.

An embodiment of the present invention displays the estimated charging time and the charging degree using the charging voltage, the battery capacity, and the current. When the charging is completed, the charging and the battery are mechanically separated or short-circuited to prevent overcharging A charge remaining amount display controller can be provided. It should be understood, however, that the technical scope of the present invention is not limited to the above-described technical problems, and other technical problems may exist.

According to an aspect of the present invention, there is provided a battery charging apparatus including a monitoring unit for monitoring a charging rate of a battery, a charging completion time and a charging remaining rate based on a monitored charging rate, And a display unit for displaying a result of the calculation unit.

According to any one of the above-described objects of the present invention, even if the battery is charged through a separate charging device other than the mobile terminal, it is possible to determine how long it takes until the battery is fully charged or the current charging rate Therefore, it is possible to easily and quickly decide whether or not to hold the battery when going out. If the battery is completely charged even if the battery is connected to the charger, the charger and the battery are physically separated or shorted in a circuit, Can be eliminated.
