Abstract

The present invention relates to a voltage booster gender for quick charging and a voltage boosting method using the same. According to the present invention, the voltage booster gender for quick charging provides a voltage booster circuit which communicates with a battery circuit in a smartphone to control whether to perform quick charging by voltage control switching to save a battery space to reduce the size of the gender, and has an embedded circuit for quick charging to improve charging performance. The voltage booster gender for quick charging uses a quick charging circuit unit to quickly charge a battery in the smartphone with charging power supplied from a general charger. The voltage booster gender for quick charging continuously monitors a battery voltage of the smartphone while the battery is charged by the quick charging circuit unit to fully charge a battery pack without degrading the battery pack.

Description

{Quick Charging Gender}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a charging device and a charging method using a gender, and more particularly, to a boosted gender for a smartphone charger having a booster circuit and a fast charging method using the same.

BACKGROUND ART As the spread of portable electronic devices having a large screen such as a smart phone expands, there is a growing interest in the lifespan of batteries that supply power to portable electronic devices. Particularly, in recent years, it has become common for users to connect to the Internet using portable electronic devices having a large screen or to reproduce downloaded image contents, so that the discharge speed of the battery, which is accommodated in the portable electronic device and supplies power, It is inconvenient for users to inconvenience that the auxiliary battery to be replaced is always carried, and when the auxiliary battery to be replaced can not be prepared, it is inconvenient to charge the auxiliary battery by using a separate charger.

However, it takes about 2 ~ 3 hours to charge the battery of the portable electronic device with the general charger. Therefore, this charging method seems very frustrating to busy modern people. In order to solve such a problem, a rapid charger which performs charging in a shorter time by supplying a charging current having a current value higher than that of a general charger has been spreading. However, such a rapid portable terminal has a built-in rechargeable battery and is configured to charge through a separate recharger. However, the portable terminals have different inconveniences in that a plurality of different chargers are provided for each portable terminal using different voltages for respective products. To solve this problem, a boost gender for boosting a voltage of 5V output from a smart phone standard charger, which is a general mobile phone charger, to a voltage corresponding to a Q.C2.0 portable terminal is provided. That is, the booster gender has an advantage in that different portable terminals can be charged with one standard charger without having a separate charger for each portable terminal.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a quick charge gender which can be connected to a smart phone battery regardless of whether a user uses a general charger or an existing battery pack, and a rapid charging method using the same.

Further, the present invention provides a gender having a booster circuit composed of general circuit elements instead of a battery, while realizing rapid charging by performing charging using a rapid charger, thereby reducing the size of the gender and reducing the production cost of the gender And to reduce errors.

According to an aspect of the present invention, there is provided a rapid charging apparatus comprising: a power input unit input from the outside through an input port; A communication unit including D + and D- terminals for communicating with the smartphone to convert the output voltage according to the state of the battery of the smartphone; A charging controller for charging the battery by charging the smart phone battery by activating normal charging according to the battery condition of the smart phone and converting the voltage value and the current value by activating rapid charging if it is determined that rapid charging is required; A switching unit for switching selectively the input voltage inputted through the input terminal according to the output voltage of the control unit; a voltage converting unit for stepping up the input voltage supplied through the switching unit to a charging voltage; And a voltage buffer unit for stably supplying the boosted charge voltage to the output terminal.

The communication port connected to the smartphone is D + and D-. If the detected voltage value is 0.6V for both D + and D-, the output voltage is 12V. If both D + and D- are 3.3V, the output voltage is 20V. When D + is 3.3V and D- is 0.6V, the output voltage is 9V. When D + is 0.6V and D- is 0V, the output voltage is 5V.

A voltage step-up method using a step-up gender for boosting a power supply to achieve the above-mentioned object, the method comprising: detecting a voltage level of the charger input to an input terminal of the gender; A second step of switching selectively providing an input voltage input through the input terminal according to an output voltage of the first step; and a second step of switching the input voltage provided through the second step A third step of boosting the charge voltage to a charge voltage, a fourth step of buffering the charge voltage boosted through the third step in a stable manner, and a step of outputting the charge voltage to an output terminal of the gender connected to the charge object It includes five steps.

. SUMMARY OF THE INVENTION The present invention provides a quick charge gender capable of charging a smart phone battery and a quick charging method using the quick charge gender, which can be connected to a user regardless of whether the user uses a general charger or an existing battery pack.

Further, the present invention provides a gender having a booster circuit composed of general circuit elements instead of a battery, while realizing rapid charging by performing charging using a rapid charger, thereby reducing the size of the gender and reducing the production cost of the gender And reduce errors.
