Description

[0001] The present invention relates to a battery charger capable of fast recharging,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a portable auxiliary battery that can be charged at a high speed, and more particularly, And a super capacitor for charging the supercapacitor at a high speed when the supercapacitor is connected to a commercial AC power source and supplying power to the portable digital device using electric energy charged to the supercapacitor when the supercapacitor is disconnected from the commercial ac power. And a battery of the portable digital device is charged. By using a supercapacitor capable of charging at a high speed even by supplying the commercial AC power for a short time within a few seconds to several minutes, By configuring to perform the battery function, It is possible to charge the auxiliary battery only by connecting the power supply for a short time within a few tens of seconds to a few minutes and at the same time charging the super capacitor built in the auxiliary battery when the AC power is connected, Which can be used as a charger for charging a battery of a connected portable digital device.

Cell phones are now a necessity indispensable to modern people. These phones usually consist largely of a body and a battery coupled to the body to supply the power needed to operate the body.

Users of mobile phones usually use one or two of these batteries and charge them by charging a battery charger using 110V or 220V commercial AC power. Depending on the user, a spare battery charged separately from the cell phone loaded with the battery is carried. When the battery mounted in the cell phone is discharged, the discharged battery is replaced with a spare battery.

In some cases, however, the battery installed in the mobile phone is discharged and the mobile phone is often turned off in a situation where the mobile phone does not have a spare battery and the charging device is also difficult to use. Particularly, in the case of urgent contact, when this happens, the user is in a difficult situation.

In recent years, a convenience store, which is located on a long distance, can receive a charging service for a mobile phone battery in preparation for such a case. However, in addition to paying a separate fee for such a service, There is a difficult inconvenience.

Accordingly, a portable auxiliary battery capable of charging the mobile phone battery while using the mobile phone is available on the market even in the case where the mobile phone charger can not be used, such as long distance travel or transportation using public transportation.

However, in the case of such a portable auxiliary battery, a large capacity battery such as a nickel-cadmium battery, a nickel-hydrogen battery, a lithium ion battery or a NAS battery which can be repeatedly charged such as a mobile phone battery is built in, Although it has the advantage of being fully charged two to three times, it takes about 5 to 6 hours to charge.

Accordingly, in a situation where the commercial AC power source can not be continuously supplied due to frequent movements without being able to charge the auxiliary battery in advance, the auxiliary battery can not be charged and used immediately, so that the auxiliary battery is also discharged, There is a problem that charging can not be performed.

In addition, since the capacity of the auxiliary battery is large, the bulky battery is inconvenient to carry, and a charger for charging the auxiliary battery separately from the mobile phone charger and an additional device for connecting the auxiliary battery and the mobile phone are always inconvenient .

In order to solve such a problem, Korean Patent No. 10-1451341 (hereinafter referred to as " prior art ") includes a secondary battery built in a cellular phone charger, and when commercial power is supplied, the cellular phone battery is charged using a commercial power source When the mobile phone battery is fully charged, the auxiliary battery is charged using the commercial power. In a place where the commercial power is not supplied, the mobile phone battery is charged through the auxiliary battery built in the charger, A description of a cell phone battery charger that can be charged while using the mobile phone, regardless of whether or not the battery is being charged.

However, the above-mentioned prior art has an advantage that a charger function for charging the mobile phone battery with only one mobile phone charger and a supplementary battery function for charging the mobile phone battery even when there is no supply of commercial power can be performed simultaneously without a separate additional device However, there is still a problem that it takes a considerably long time to charge the battery because the battery is used for a general mobile phone.

In addition, since the conventional technique can not simultaneously charge the mobile phone battery and the auxiliary battery, the mobile phone battery is fully charged and then the auxiliary battery is charged, so that the auxiliary battery functions properly as the auxiliary battery In order to do so, the mobile phone battery must be fully charged, and the commercial power must be continuously supplied until the auxiliary battery is charged. If the commercial battery is not supplied until the auxiliary battery is charged, There is a problem that the function as a battery is not properly performed.

In addition, when the AC power is supplied, the battery of the portable digital device connected to the super capacitor It can be used as a charger for charging the battery.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, each configuration of a battery charger and a portable auxiliary battery capable of high-speed charging according to an embodiment of the present invention will be described in detail.

2, the power input unit 110 is provided at one side of the portable auxiliary battery 100, and supplies the AC auxiliary power to the portable auxiliary battery 100 through a commercial AC power source.

For this purpose, a plug for AC 110V or AC 220V may be formed in the power input unit 110 so as to receive a commercial AC power of 110V or 220V, or may be connected to a power cable so as to receive a commercial AC power. Terminals (not shown) may be formed.

That is, a plug for AC 110V or AC 220V protruding outside the portable auxiliary battery 100 is formed in the power input unit 110, and is directly connected to the power outlet to receive the commercial AC power, And a separable power input terminal, so that the commercial AC power can be received through the power cable.

The AC to DC converter 120 is connected to the power input unit 110 and converts the AC power input through the power input unit 110 to a DC power.

The DC power converted through the AC / DC converter 120 is supplied to the supercapacitor 130 connected to the AC / DC converter 120 to be charged. At this time, the supercapacitor 130 is charged with the normal capacity (Ultra Capacitor) or ultra-high-capacity battery, which is a relatively large capacitor compared to a general capacitor of the present invention, and a voltage of several volts is applied to both ends of a unit cell electrode, ions in the electrolyte move along the electric field, The battery can be rapidly charged unlike a general battery using a chemical reaction, and has characteristics of high charge / discharge efficiency and semi-permanent cycle life.

When the commercial AC power is input to the power input unit 110, the commercial AC power is supplied to the super-capacitor 130 within a few tens of seconds to several minutes after the commercial AC power is input, Since the charging of the capacitor 130 is completed, the charging time can be shortened to about 1/20 or less as compared with the conventional auxiliary battery of the same capacity, so that the auxiliary battery can be charged only by connecting the power source for a short time.

In other words, for example, in the case of a smartphone as one of portable digital devices, a lithium-ion battery having a capacity of about 2600 mAh is generally used. The storage energy of the lithium-ion battery is about 9.88 Wh, It takes about 3 hours, and a fully charged lithium-ion battery can be used for about 8 hours.

On the other hand, in the case of a supercapacitor having a capacitance of 900F, it takes about several tens of seconds to several minutes to fully charge the storage energy to about 1.02 Wh, and the chargeable energy The speed is about 20 times faster.

Generally, the super capacitor has relatively less energy to be stored than a commonly used lithium-ion battery. When the auxiliary battery is constructed using the supercapacitor, when a lithium-ion battery of a similar size is used Although it can not store only about 1/4 to 1/5 of the energy, it can be overcome by the fast charging speed of the supercapacitor.

In other words, if the auxiliary battery is constructed by using the super capacitor, it is possible to fully charge the super capacitor even by supplying the commercial AC power for a short time shorter than 1/20 of the general auxiliary battery, Can be recharged at any time with just a few seconds of power (for example, by connecting to a commercial power supply for short periods of time, such as visiting a coffee shop, restaurant, or meeting in the office, etc.) It is possible to supply power necessary for the portable digital device. In addition, when it is connected to a commercial AC power source, it can be used as a charger for charging a battery of a portable digital device connected to the supercapacitor built in the auxiliary battery at the same time, so that even if the storage capacity is relatively small, It is possible.

The power regulator 140 receives the DC power discharged through the supercapacitor 130 and adjusts the output to match the allowable input power of the portable digital device 200 connected to the portable auxiliary battery 100. [ For example, in the case of a general smartphone, the power regulator 140 needs to supply DC 5V, 1A, or DC 5V, 2A. Therefore, DC 5V, and 2A, respectively.

That is, the output regulating unit 140 is provided with a voltage ascending / descending circuit (not shown) capable of stepping up or down the DC power supplied through the supercapacitor 130, and is connected to the portable auxiliary battery 100, It is possible to adjust the output to match the allowable input power of the device 200 and to maintain the output constantly so that it can be applied to various types of portable digital devices and can be used not only for portable digital devices Thereby preventing damage to the apparatus.

Here, the output range of the direct current power output through the output controller 140 is not limited to the range described in the present embodiment, but may be applied to various kinds of portable digital devices connected to the portable auxiliary battery 100 Of course, the output range can be changed and applied.

The power output unit 150 is connected to the output control unit 140 and supplies DC power output through the output control unit 140 to the portable digital device 200. The portable digital device 200 Output connector (I / O connector).

That is, the power output unit 150 is provided with a power output terminal (not shown) that can be connected to and disconnected from the charging cable of the portable digital device 200, through the charging cable, And is configured to supply the DC power output through the output control unit 140 to the portable digital device 200 by being connected.

In this case, the power output terminal may be configured as a USB terminal to be connected to a charging cable of a general portable digital device. In addition, a micro 5-pin USB terminal, an 8-pin lightning terminal, or an Apple 30 Pin terminal or the like.

The control unit 160 controls charging / discharging operations of the auxiliary battery 100 by detecting whether the commercial AC power source is input and whether the portable digital device 200 is connected.

That is, when the input of the commercial AC power is detected through the power input unit 110, the controller 160 controls the power input through the power input unit 110 to be charged to the supercapacitor 130 at high speed, When the portable digital device 200 is connected to the power supply unit 150, the DC power charged in the supercapacitor 130 is gradually discharged to be supplied to the output control unit 140, So that power is supplied to the device 200 and the battery of the portable digital device 200 can be charged.

When the connection of the portable digital device 200 is sensed through the power output unit 150 while the supercapacitor 130 is being charged while being connected to the commercial AC power, the controller 160 controls the supercapacitor 130 May be controlled so that the charging and discharging operations of the battery pack 1 and the battery pack 2 simultaneously occur.

In other words, when the input of the commercial AC power source and the connection of the portable digital device 200 are detected at the same time, the control unit 160 causes the power input through the power input unit 110 to be charged in the supercapacitor 130 The DC power supplied to the portable digital device 200 through the power output unit 150 is supplied to the portable digital device 200 by controlling the DC power charged in the supercapacitor 130 to be gradually discharged, And the battery of the portable digital device 200 is charged.

In this process, when the charging of the supercapacitor 130 is completed, the controller 160 cuts off the power supply line through the supercapacitor 130 and supplies the DC power supplied through the AC / To the output control unit 140 and provides the digital output signal to the portable digital device 200 connected to the power output unit 150.

The portable auxiliary battery 100 according to the present invention is capable of continuously supplying the commercial AC power to the auxiliary battery 100 only by connecting the power for a short time within a few tens of seconds to several minutes And can be used as a charger for charging the battery of the portable digital device 200 connected to the supercapacitor 130 when the AC power is connected.

Accordingly, the portable auxiliary battery 100 according to the present invention performs the functions of the auxiliary battery and the charger simultaneously with only one portable auxiliary battery 100 without carrying the separate charger for charging the auxiliary battery and the portable digital device separately And at the same time, it is possible to provide power through rapid charging of the auxiliary battery 100 in a relatively short time.

As described above, according to the present invention, in constructing the auxiliary battery of the portable digital device, the auxiliary battery is provided with a super capacitor (super capacitor) capable of charging / discharging at a high speed by receiving commercial AC power, When the connection with the commercial AC power source is canceled, power is supplied to the portable digital device using the electric energy charged in the super capacitor, So that the auxiliary battery function of the portable digital device is performed by using the super capacitor capable of high-speed charging even by supplying the commercial AC power for a short time within a few seconds to several minutes, Even in a situation where AC power can not be supplied, The auxiliary battery can be charged only by a power supply for a short time within a few minutes, so that it can be charged while using a portable digital device without restriction of a charging time or place.

In addition, when the commercial AC power source is connected, the super capacitor built in the auxiliary battery is charged and the battery of the portable digital device connected thereto is charged so that a separate charger for charging the portable digital device or the auxiliary battery is separately provided There is an advantage in that the auxiliary battery can be charged and the battery of the portable digital device can be charged at the same time with the auxiliary battery alone.

It is to be understood that the present invention is not limited to the above-described embodiment and the accompanying drawings, and that various substitutions, modifications, and alterations can be made within the scope of the technical idea of the present invention, It is obvious to those who have.
