Meanwhile, in the bag 100 capable of wireless charging according to the present invention, power supplied from the battery 130 is supplied to the charging object side in a wireless manner.

A wireless power transmission antenna 150 for transmitting the power supplied from the battery 130 by wireless power is built in the housing main body 121 and the wireless power transmission antenna 150 is connected to the circuit unit 140, respectively.

The antenna for wireless power transmission 150 may be formed of a flat coil of a polygonal shape such as a circular shape, an elliptical shape, a spiral shape or a quadrangular shape wound in a clockwise or counterclockwise direction, The metal foil may be etched or printed in a predetermined pattern using a conductive ink.

Here, when the antenna 150 for wireless power transmission is formed in a pattern on the circuit board, the circuit board may be formed integrally with the circuit board constituting the circuit unit 140 or may be formed of a separate member .

The wireless power transmission antenna 150 serves as a wireless power transmission antenna for transmitting wireless power to the wireless power receiving antenna 18 provided in the charging object 10, ).

The driving power of the circuit unit 140 for driving the wireless power transmission antenna 150 may be a part of the power stored in the battery 130. In one side of the storage unit 121, A switch (not shown) for supplying or cutting off power to the power supply 140 may be exposed to the outside.

For example, when power is supplied to the circuit unit 140 through the battery 130, the power supplied from the battery 130 is converted into a constant voltage and current through the converting unit 142, 143 to convert the DC power supplied from the battery 130 to AC power, and then transmit the wireless power through the antenna 150 for wireless power transmission.

Here, the circuit unit 140 controls the overall operation and generates a control signal for controlling characteristics of a frequency, an applied voltage, and a current used for generating a power signal transmitted from the antenna 150 for wireless power transmission And the power signal includes information including at least one of power amount information of the object to be charged, charge state information, power information suitable for the load requested by the object to be charged, and identification information .

Accordingly, the wireless power receiving antenna 18 provided in the charging object 10 generates electric power by using the electromagnetic field transmitted from the antenna 150 for wireless power transmission, so that the main battery of the charging object 10 Is charged.

At this time, the wireless power transmission antenna 150 transmits the power of the battery 130 by wireless power to charge the main battery of the charging object 10, and receives wireless power from the external charging device, And charging the power source of the battery 130.

That is, the antenna 150 for wireless power transmission can perform the function of an antenna for transmitting a wireless power or the function of an antenna for wireless power reception according to the purpose of use through one antenna.

In other words, the wireless power transmission antenna 150 may be used as an antenna for wireless power transmission, and may be operated in a transmission mode for charging the main battery to be charged using the power stored in the battery 130, May be used as a power receiving antenna, and may be operated in a receiving mode for receiving wireless power supplied from an external charging device to charge the battery 130.

That is, when the charging object equipped with the wireless power receiving module approaches the wireless power transmission antenna 150, the wireless power transmission antenna 150 is switched to the antenna for wireless power transmission and is implemented in the wireless power transmission mode , And when the wireless power transmission module approaches the wireless power transmission antenna 150, the wireless power transmission antenna 150 may switch to the wireless power reception antenna and be implemented in the wireless power reception mode.

Also, the wireless power transmission antenna 150 operates as an antenna for wireless power reception for charging the battery 130 in a transmission mode operated by an antenna for wireless power transmission for charging the main battery to be charged Reception mode.

For example, the wireless power transmission antenna 150 operates in a transmission mode for transmitting wireless power so as to charge the main battery of the object to be charged when a charging object equipped with the wireless power receiving module is nearby, The wireless power transmission antenna 150 may be switched to a reception mode for charging the battery 130 in the transmission mode.

Here, the principle of power transmission / reception using the antenna 150 for wireless power transmission can be applied to both a known magnetic induction method and a self-resonance method for generating an electromagnetic field using a coil and transmitting electric power through the coil. Since the wireless charging technique using the magnetic induction method and the self-resonance method is a well-known technology, a detailed description thereof will be omitted.

At this time, the wireless power transmission antenna 150 may be changed to a reception mode and a transmission mode by a user operating a separate switch (not shown), but the reception mode and the transmission mode Can be changed.

For example, the circuit unit 140 switches the wireless power transmission antenna 150 to an antenna for wireless power transmission when the charging object 10 equipped with the wireless power receiving module approaches the wireless power transmission module, The antenna for wireless power transmission 150 can be switched to the antenna for wireless power reception.

In addition, the circuit unit 140 may be switched from the transmission mode to the reception mode when the external power charger is in a state where the wireless power transmission antenna 150 is operated in the transmission mode for charging the main battery to be charged .

Specifically, when the power is supplied to the circuit unit 140, the wireless power transmission antenna 150 operates in a transmission mode for performing a function of a wireless power transmission antenna, and controls the circuit unit 140 A power signal for detecting proximity of the wireless power receiving module may be transmitted to the outside through the antenna 150 for a predetermined period.

In this case, if the inductance of the antenna 150 for wireless power transmission changes during the transmission of the power signal by the antenna 150 for wireless power transmission and another power signal transmitted from the outside is not detected, 140 can determine that the charging object equipped with the wireless power receiving module is close.

Accordingly, the circuit unit 140 consumes power stored in the battery 130 by adjusting the amount of power transmitted through the wireless power transmission antenna 150 according to the load required by the wireless power receiving module, The main battery is charged.

In addition, when the wireless power transmission antenna 150 operates in the transmission mode as described above, a power signal for sensing the proximity of the wireless power reception module is transmitted through the wireless power transmission antenna 150 at regular intervals When the external power source signal is detected by the circuit unit 140 in response to the change of the inductance of the antenna 150 for wireless power transmission, It can be judged that the period is close.

Accordingly, the circuit unit 140 converts the wireless power transmission antenna 150 into the reception mode, and receives the wireless power transmitted from the wireless power transmission module of the external charging device through the wireless power transmission antenna 150 The battery 130 is charged.

For this, the circuit unit 140 may include various circuits for operating the wireless power transmission antenna 150 in a reception mode and a transmission mode.

For example, the circuit unit 140 controls the overall operation of the circuit unit 140 as shown in FIG. 5, and a frequency used to generate a power signal transmitted from the antenna 150 for wireless power transmission, And a control unit 141 for generating a control signal for controlling characteristics of a voltage, a current, and the like.

Herein, the controller 141 performs a process of identifying the wireless power receiving module and the wireless power transmitting module according to a result of detecting the presence of the wireless power receiving module and the wireless power transmitting module, Or to generate a control signal for switching the antenna 150 for the wireless power transmission from the transmission mode to the reception mode when detecting the proximity of the wireless power transmission module.

The circuit unit 140 converts the power supplied from the battery 130 to a predetermined voltage and current or converts the power received through the antenna 150 to a constant voltage and current suitable for the battery 130. [ And provides the converted signal to the battery 130 side.

In addition, the circuit unit 140 may include an inverter unit 143 for converting a DC power supplied from the battery 130 to an AC power, and may include an external unit (not shown) A rectifier 145 for converting a power source from an AC power source to a DC power source and a voltage lower portion 144 for lowering the DC power converted by the rectifier 145 to a voltage suitable for the battery 130. [ . ≪ / RTI >

Here, the controller 141 may be a well-known MCU, a PWM control scheme, and the voltage lower part 144 may be implemented by either an LDO scheme or a Buck scheme. In addition, the circuit unit 140 may include a protection circuit such as a PCM or the like to prevent overcharge or protect various circuits.

In addition, the circuit unit 140 switches the antenna 150 for radio power transmission to perform a function of an antenna for transmitting a radio power when the radio power receiving module is in proximity to the radio power transmitting module, And a switching circuit for switching the antenna 150 to perform the function of the antenna for wireless power reception.

The circuit unit 140 may be implemented by mounting various circuit patterns on the circuit board 147 and at least one chipset or diode and various passive elements (ex, resistors, capacitors, etc.).

The antenna 150 for wireless power transmission according to the present invention is a transmission mode for charging the main battery of the charging object 10 by using the power stored in the battery 130 through the control of the circuit unit 140 Or may be operated in a receiving mode in which the battery 130 is charged by receiving wireless power supplied from an external charging device.

For example, when the main battery to be charged is to be charged through the charging accommodating member 120 according to the present invention, the charging object is inserted into the accommodating space S. When the power of the battery 130 is supplied to the circuit unit 140, the wireless power transmission antenna 150 operates in the transmission mode by sending the power signal generated by the control unit 141 to the outside at regular intervals. .

The power supplied from the battery 130 may be converted into a constant voltage and current through the converter 142 and then supplied to the controller 141. The inverter 143 converts the power from the DC power to the AC power And then supplied to the antenna 150 for wireless power transmission to transmit a power signal having a predetermined period to the outside.

Thereafter, in the course of transmitting the power signal, the antenna 150 for wireless power transmission interacts with the receiving antenna of the wireless power receiving module included in the charging object to generate the inductance of the wireless power transmitting antenna 150 In the case where a change occurs and no other power signal is detected, the circuit unit 140 consumes power stored in the battery 130 by adjusting the amount of power according to the load required by the wireless power receiving module to be charged, The main battery is charged.

Meanwhile, when the battery 130 needs to be charged, the battery 130 may be charged in a wireless manner by bringing a charger including the wireless power transmission module closer to the charging accommodation member 120.

That is, the wireless power transmission antenna 150 is brought close to the charger in a state where the wireless power transmission antenna 150 operates in the transmission mode in which the power signal is transmitted by the circuit unit 140 at a constant cycle. Accordingly, the inductance of the wireless power transmission antenna 150 is changed by the interaction with the antenna for wireless power transmission of the wireless power transmission module included in the charger. When the control unit 140 senses that another power signal transmitted from the charging device is detected by the controller 140, the controller 140 recognizes that the charger is in proximity and disconnects the power supplied to the inverter unit 143, The antenna 150 is switched to a reception mode in which it operates as an antenna for wireless power reception.

Here, the control unit 141 may transmit information including at least one of electric power amount information, state information of the battery 130, state information of the battery 130, electric power information suitable for the load requested by the object to be charged, .

Therefore, the wireless power transmission antenna 150 operating in the receiving mode charges the power of the battery 130 by receiving the wireless power provided by the charging device in a state suitable for the battery 130. [

Here, the power received through the antenna 150 for wireless power transmission is converted from an AC power source to a DC power source through the rectifying unit 145, and a voltage of a voltage suitable for the battery 130 And then the battery 130 is supplied with a constant voltage and current by the conversion unit 142, so that the battery 130 can be charged.

As described above, the charging accommodation member 120 according to the present invention transmits and receives power wirelessly to charge the main battery to be charged or to charge the battery 130, Charging / discharging is performed by a simple method of storing a charging object in the receiving member 120 or placing the charging receiving member 120 on an external charger, thereby improving the usability.

In addition, since the port, which is a necessary component for connecting the cable in the conventional wire charging / discharging system, is removed, the foreign matter caused by the port and the failure due to moisture penetration can be prevented, and the service life of the auxiliary battery can be extended .

The battery 130 is built in the housing main body 121 to supply power for charging the main battery of the charging object 10.

The battery 130 may be a known battery having rigidity. However, even if the storage body 121 made of a soft material is deformed due to an external force during its use, Or a flexible battery having flexibility so that the problem of performance deterioration does not occur (see Fig. 11).

11 to 13, the flexible battery includes an electrode assembly 131 and exterior materials 137 and 138. The electrode assembly 131 is encapsulated with the electrolytic solution together with the exterior materials 137 and 138. [

At this time, the electrode assembly 131 and the facings 137 and 138 may be provided with patterns 136 and 139 for contraction and relaxation, respectively. For example, the contraction and relaxation patterns 136 and 139 may be formed along the longitudinal direction or the width direction of the electrode assembly 131 and the facings 137 and 138, and the first patterns 137 and 138 formed on the facings 137 and 138 139 and the second pattern 136 formed on the electrode assembly 131 may have the same directionality (see FIGS. 12 and 13).

Such patterns 136 and 139 can prevent or minimize the shrinkage or relaxation of the substrate itself by canceling the amount of change caused by the curvature at the time of deformation even if deformation of the accommodating body 121 occurs during use.

For example, when the housing body 121 is made of a soft material and deformation of the housing body 121 occurs during use, it is possible to prevent the battery 130 from being damaged due to such deformation.

That is, since the deformation amount of the base material itself constituting the electrode assembly 131 and the outer packaging materials 137 and 138 is prevented or minimized, the deformation of the storage body 121, for example, the deformation amount of the base material itself, It is possible to prevent the electrode assembly 131 and the sheathing members 137 and 138 from being damaged or deteriorated in performance.

At this time, the first pattern 139 and the second pattern 136 are disposed so that the first pattern 139 and the second pattern 136 coincide with each other, as well as the same directionality. This is because the first pattern 139 and the second pattern 136 can always have the same behavior.

In other words, when the battery 130 according to the present invention is provided as a flexible battery, patterns 136 and 139 for shrinking and relaxing in the longitudinal direction, which are generated when the electrode assembly 131 and the sheathing members 137 and 138 are bent, The electrode assembly 131 and the casing members 137 and 138 can always maintain a uniform gap or contact state with respect to the entire length of the electrode assembly 131 and the electrode assembly 131 together with the electrode assembly 131, It is possible to prevent the performance of the battery from deteriorating due to uniform distribution of the electrolyte solution over the entire length.

This can be confirmed by the graphs of Figs. 14A and 14B.

That is, when a force is applied to both ends of the flexible battery in an environment of a temperature of 25 ° C and a humidity of 65%, and the curvature in the bent portion is made to be 25 mm, and charging and discharging are performed 100 times, When the pattern was formed on both the electrode assembly 131 and the outer cover materials 137 and 138, the capacity was reduced by about 15% (110 mAh) compared with the capacity (130 mAh) when the bending was not performed. (Example), a flexible battery having a pattern for shrinkage and relaxation only on the exterior material side showed a performance gradually falling from a capacity reduced by about 60% (52 mAh) compared to the initial capacity, and it was impossible to charge / In the case of the flexible battery having a simple plate shape in which no pattern is formed in both the casing and the electrode assembly, a capacity of about 80% reduced from the initial capacity (26 mAh) It was confirmed that charging and discharging were impossible when the deterioration occurred and exceeded 30 times (Comparative Example 2).

On the other hand, in the environment of a temperature of 25 ° C and a humidity of 65%, the middle of the length of the flexible battery was completely folded back to the original state, and the voltage in the battery was measured with time. As a result, 131 and the exterior materials 137 and 138, there was no change in the voltage value (Example), but a flexible battery having a pattern for contraction and relaxation only on the exterior material side (Comparative Example 1) And the flexible battery (Comparative Example 2) having a simple plate-like shape in which no pattern was formed in both of the electrode assemblies and the electrode assemblies was found to be deteriorated in voltage value.

In other words, in the case where the outer sheathing members 137 and 138 and the electrode assembly 131 are formed so that the patterns 136 and 139 for shrinking and relaxing are formed to coincide with each other, the degradation of performance does not occur largely even if banding occurs, Cracks are generated by bending or leakage of electrolyte occurs, and the performance of the battery deteriorates.

As described above, the flexible battery according to the present invention is formed such that the patterns 136 and 139 for contraction and relaxation in the longitudinal direction generated during bending on the electrode assembly 131 and the facings 137 and 138 coincide with each other, Since the electrode assembly 131 and the casing members 137 and 138 can always maintain uniform intervals or contact with the entire length thereof, the electrolyte solution sealed together with the electrode assembly 131 is uniformly distributed over the entire length, It is possible to prevent degradation of performance.

At this time, the pattern may be formed entirely or partially in the flexible battery.

At this time, the first pattern 139 and the second pattern 136 may be formed in a direction parallel to the width direction of the casing member 137 and the electrode assembly 131, respectively, 137 and 138 and the electrode assembly 131 along the longitudinal direction of the electrode assembly 131 (see FIG. 12).

The first pattern 139 and the second pattern 136 may be formed such that the first and second patterns 139 and 137 are formed at the same positions of the first and second patterns 139 and 137, 136 may conform to each other.

The patterns 136 and 139 may be continuously formed in a direction parallel to the width direction of the electrode assembly 131 and the casing materials 137 and 138 or discontinuously formed therebetween. 137, 138, and may be partially formed with respect to a part of the length.

The crests and valleys may be formed to have arcuate cross-sections including semicircles, polygonal cross-sections including triangular or rectangular cross-sections, and cross-sections of various shapes in which arc-shaped cross-sections and polygonal cross-sections are mutually combined. Pitch and width, but they may be provided to have different pitches and widths.

This makes it possible to reduce the degree of fatigue applied to the substrate itself through the patterns 136 and 139, even if the casing members 137 and 138 and the electrode assembly 131 are embedded in the housing body 121 while being bent.

Meanwhile, the first pattern 139 and the second pattern 136 may be formed so that the intervals between the adjacent horns or between the valleys may be the same or may be different from each other, Gaps may be provided in a combined form.

That is, the positive electrode 132 and the negative electrode 134 can be pressed, deposited, or coated with active materials 132b and 134b on one or both surfaces of the current collectors 132a and 134a. At this time, the active materials 132b and 134b may be provided with respect to the entire area of the current collectors 132a and 134a or partially with respect to a certain area.

The positive electrode collector 132a and the negative electrode collector 134a may be formed with a negative electrode terminal 135a and a positive electrode terminal 135b for electrical connection with an external device from each body. The anode terminal 135b and the anode terminal 135a may be formed to extend from the cathode current collector 132a and the anode current collector 134a and protrude from one side of the case members 137 and 138, 137, 138, respectively.

At this time, the cathode active material 132b and the anode active material 134b may contain a PTFE (Polytetrafluoroethylene) component. This is to prevent peeling or cracking of the cathode active material 132b and the anode active material 134b from the current collectors 132a and 134a at the time of bending.

The separation membrane 133 disposed between the anode 132 and the cathode 134 may include a nanofiber web layer 133b on one side or both sides of the nonwoven fabric layer 133a.

Here, the nanofiber web layer 133b may be a nanofiber containing at least one selected from the group consisting of polyacrylonitrile nanofiber and polyvinylidene fluoride nanofiber.
