Description

Smart wired / wireless charger and its operating method

[0001] The present invention relates to a smart wired / wireless charger and a method for operating the same. More specifically, the present invention relates to a smart wired / wireless charger and a method for operating the same, which can detect charging information of another electronic device paired with an electronic device being charged and provide a user with information on whether charging is necessary.

[0002] With the recent rapid development of information and communication technology, a ubiquitous society based on information and communication technology is being realized. To ensure that electronic devices for information and communication can be accessed anytime and anywhere, sensors embedded with computer chips with communication capabilities must be installed in all social facilities.

[0003] Therefore, the power supply problem for these electronic devices and sensors has become a new challenge. Furthermore, with the rapid expansion of portable electronic devices, including not only mobile phones but also wearable watches, Bluetooth headsets, and music players like iPods, new wireless power transmission technologies and wireless power devices are being developed.

[0004] Wireless power transmission technology (wireless energy transfer) can be broadly categorized into magnetic induction, electromagnetic resonance, and short-wave radio frequency (RF) transmission methods depending on the energy transfer method.

[0005] In particular, most wireless energy transmission methods, not only in mobile devices but also in IT technology, currently utilize wireless charging systems utilizing magnetic induction. For example, portable electronic devices such as cordless toothbrushes, cordless razors, smartphones, smartwatches, wireless earphones, and laptop computers utilize electromagnetic induction for charging.

[0006] Among the electronic devices utilizing wireless charging technology, the most widely used are portable terminals, and Patent Document 1 (Patent Registration No. 10-1738073) proposes a technology that enables wireless charging while a portable terminal is placed on the device.

[0007] Additionally, technology is being developed to allow for the charging of various electronic devices by placing them on a wireless charger, as described in Patent Document 1. For example, multiple charging coil areas for magnetic induction are placed in multiple locations, enabling the wireless charging of wearable watches, Bluetooth devices, and other devices alongside portable terminals. This allows for the simultaneous charging of multiple electronic devices with a single wireless charger.

[0008] However, because conventional wireless chargers simply focused on expanding the physical charging space, charging of electronic devices was limited to the user's choice, allowing them to charge additional electronic devices from a single wireless charger. This meant that if the user didn't separately check the remaining battery level of another electronic device paired with the mobile device being charged, charging for that device would not proceed.

[0009] The present invention aims to provide a smart wired / wireless charger and a method for operating the same, which can extensively manage remaining battery capacity by detecting charging information of another electronic device paired with an electronic device being charged and providing a user with information on whether charging is necessary.

[0010] The present invention aims to provide a smart wired / wireless charger and a method for operating the same, which allows a user to manage the batteries of peripheral electronic devices by arranging a second charging unit capable of charging a second electronic device inside a first charging unit capable of charging a first electronic device and allowing the second charging unit to be withdrawn from the first charging unit according to the remaining battery capacity of the second electronic device.

[0011] The present invention aims to provide a smart wired / wireless charger and a driving method thereof that improves space utilization efficiency of the charger by arranging a moving means between an inner region of a first charging unit and a second charging unit and allowing the second charging unit to be inserted into or withdrawn from the first charging unit according to charging needs.

[0012] The present invention aims to provide a smart wired / wireless charger and a method for operating the same, which can detect a second electronic device paired with a first electronic device being charged, detect the remaining battery level of other electronic devices in the vicinity, and perform battery management for electronic devices with low remaining battery levels.

[0036] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. When describing with reference to the drawings, identical or corresponding components are given the same drawing reference numerals, and redundant descriptions thereof will be omitted.

[0037]

[0038] FIGS. 1 to 3 are drawings illustrating the structure of a smart wired / wireless charger according to an embodiment of the present invention.

[0039] Referring to FIGS. 1 to 3, the smart wireless charger (10) of the present invention includes a first charging unit (100), a second charging unit (200), and a power cable (300) for supplying power.

[0040] The first charging unit (100) includes a first front (110) and a first rear (120) constituting the first charging body unit, and a chin (190) disposed on the first front (110) to support a portable terminal. The first front (110) and the first rear (120) constituting the first charging body unit each have one side integrally connected to each other, and the other side of each has a structure in which they contact the ground and support each other. Accordingly, the first front (110) and the first rear (120) each have an inclined surface that slopes in a predetermined direction upward from the horizontal ground.

[0041] The second charging unit (200) has a triangular cross-section and can be positioned between the first front (110) and the first rear (120). In addition, the second charging unit (200) of the smart wired / wireless charger of the present invention can move from the inner region of the first charging body to the outer region of the first charging body, for example, between the first front (110) and the first rear (120).

[0042] More specifically, the second charging unit (200) includes a second charging body unit composed of a second front (210), a second side (230), and a second rear (220).

[0043] The second charging unit (200) can be reciprocally moved, such as inserted or withdrawn, in the inward or outward (lateral) direction of the first charging body unit between the first front (110) and the first rear (120). When the second charging unit (200) is inserted into the inward direction of the first charging body unit, the second side surface (230) of the second charging unit (200) forms the same plane as the first side surface (130) formed along one side of the first front (110) and one side of the first rear (120).

[0044] That is, when the second charging part (200) is inserted into the inside of the first charging body part, the first side (130) and the second side (230) form the same plane, and when the second charging body part is pulled outward to charge a portable terminal or other electronic device such as a paired electronic device, the second charging body part protrudes in a direction perpendicular to the first side (130) (the side of the first front or the side of the first rear).

[0045] The smart wired / wireless charger (10) of the present invention can provide wired and wireless charging functions for portable terminals or electronic devices. Although not explicitly shown in the drawing, the jaw portion (290) supporting the portable terminal may include a power terminal that can be connected to the power terminal of the portable terminal.

[0046] Additionally, the second charging unit (200) can provide wireless charging and wired charging functions for electronic devices paired with the portable terminal or other electronic devices. Although not shown in the drawing, a power terminal that can be connected to an electronic device can be placed on the second front (210) or second rear (220) area of ​​the second charging unit (200).

[0047] The smart wired / wireless charger (10) of the present invention is configured such that a wireless charging module having induction coils for generating electromagnetic induction is disposed in each of the first charging unit (100) and the second charging unit (200). Accordingly, the first charging unit (100) and the second charging unit (200) can wirelessly charge a portable terminal or electronic device by means of electromagnetic induction.

[0048] In particular, the smart wired / wireless charger (10) of the present invention can search for an electronic device paired with a portable terminal placed in the first charging unit (100) for charging. Furthermore, when a paired electronic device is searched, power information can be acquired to determine whether the paired electronic device requires charging, thereby providing the information to the user.

[0049] For example, when a portable terminal is placed on the first charging unit (100) for charging, the smart wireless charger (10) of the present invention can obtain battery power information from an electronic device (smart watch, wireless earphones, wireless headphones, etc.) paired with the portable terminal and can withdraw the second charging unit (200) from the first charging unit (100) according to the remaining battery level.

[0050] That is, the smart wired / wireless charger (10) can search for electronic devices paired with a portable terminal or electronic devices capable of performing wired / wireless charging operations, and determine whether battery charging is necessary based on the preset remaining battery level for each electronic device.

[0051] If the battery information of the searched electronic device is below a preset value, the smart wireless charger (10) can provide the user with an alarm in the form of an alert to inform the user of the need to charge the surrounding electronic device (electronic device paired with a portable terminal or electronic device capable of being wirelessly charged).

[0052] In addition, the smart wired / wireless charger (10) of the present invention can automatically withdraw the second charging unit (200) from the first charging unit (100) when the remaining battery capacity of the electronic device searched for battery charging is below a preset value, thereby notifying the user of the need for charging the searched electronic device.

[0053] Accordingly, the smart wired / wireless charger (10) of the present invention can detect battery remaining information for electronic devices linked to the electronic device being charged or electronic devices in the vicinity, and manage whether the batteries of the surrounding electronic devices are being charged.

[0054] In this way, the smart wired / wireless charger of the present invention and its driving method have the effect of enabling extensive battery remaining capacity management by detecting charging information of another electronic device paired with the electronic device being charged and providing the user with information on whether charging is necessary.

[0055] The smart wired / wireless charger of the present invention and its driving method have the effect of arranging a second charging unit capable of charging a second electronic device inside a first charging unit for charging a first electronic device, and allowing the second charging unit to be withdrawn from the first charging unit according to the remaining battery capacity of the second electronic device, thereby enabling a user to manage the batteries of peripheral electronic devices.

[0056] The smart wired / wireless charger of the present invention and its driving method have the effect of improving the space utilization efficiency of the charger by arranging a moving means between the inner area of ​​the first charging unit and the second charging unit and allowing the second charging unit to be inserted into or withdrawn from the first charging unit as charging is required.

[0057] The smart wired / wireless charger of the present invention and its driving method have the effect of detecting a second electronic device paired with a first electronic device being charged, detecting the remaining battery level of other electronic devices in the vicinity, and managing the battery of an electronic device with a low remaining battery level.

[0058] FIG. 4 is a diagram illustrating a smart watch paired with a portable terminal being charged using a smart wired / wireless charger according to an embodiment of the present invention. FIGS. 5 and 6 are exploded perspective views of a smart wired / wireless charger according to an embodiment of the present invention. FIG. 7 is a diagram illustrating the structure of a first charging unit of a smart wired / wireless charger according to an embodiment of the present invention.

[0059] Referring to FIGS. 4 to 7, the smart wireless charger (10) of the present invention includes a first charging unit (100), a second charging unit (200), and a power cable (300) for supplying power.

[0060] The first charging body part of the first charging part (100) has a structure in which the first front side (110) and the second rear side (120) are inclined in a direction facing each other with respect to the ground. Therefore, the lower side of the first front side (110) of the first charging part (100) and the lower side of the first rear side (120) of the first charging part (100) are in contact with the ground, and the upper side of the first front side (110) of the first charging part (100) and the upper side of the first rear side (120) of the first charging part (100) are in contact with each other. That is, the side cross-section of the first charging part (100) is formed in a triangular structure.

[0061] Additionally, a second charging unit (200) having surfaces facing parallel to the respective inner surfaces of the first front surface (110) and the first rear surface (120) of the first charging unit (100) is arranged. The second charging unit (200) can be inserted or withdrawn in a sliding manner along the inner surfaces of the first front surface (110) and the first rear surface (120).

[0062] As illustrated in the drawing, when a portable terminal is placed on the first front surface (110), the second charging unit (200) is withdrawn from the first charging unit (100) to charge the electronic device paired therewith or another electronic device. Although the drawing illustrates a smartwatch that is frequently paired with the portable terminal, this is merely an example, and various electronic devices may be placed on the second charging unit (200).

[0063] Additionally, the structure of the second charging unit (200) can be changed in various ways depending on the type of electronic device placed in the second charging unit (200).

[0064] The smart wireless charger (10) of the present invention may be equipped with a first charging module (150) for wireless charging. The first charging module may be placed within the first front surface (100) of the first charging unit (100).

[0065] The first charging module (150) may include at least one coil region according to an electromagnetic induction charging method. Additionally, although not shown in the drawing, the jaw portion (190) for securing the portable terminal may further include a charging terminal for wired charging.

[0066] Accordingly, the jaw portion (190) can secure the portable terminal placed on the first front surface (110) while supplying power to the portable terminal. As illustrated in FIG. 5, the jaw portion (190) can be assembled by being fastened to the first fastening portion (111) placed on the lower side of the first front surface (110).

[0067] In addition, the smart wired / wireless charger (10) of the present invention may include a main circuit unit (160) that controls the operations of the first charging unit (100) and the second charging unit (200), processes information about an electronic device that requires charging for a user, and performs overall control of the smart wired / wireless charger (10). The main circuit unit (160) may be placed inside or outside the first rear surface (120).

[0068] Referring to FIGS. 5 to 7, the inner side (140) of the first front side (110) and the first rear side (120) of the smart wired / wireless charger (10) of the present invention includes a first inner side (141) of the first front side (110) and a second inner side (142) of the first rear side (120).

[0069] Since the first and second inner surfaces (141) are areas where the aforementioned second charging unit (200) is arranged, they may include first and second guide grooves (141g, 142g: see FIG. 7) so that the second charging unit (200) can be inserted or withdrawn in a sliding manner.

[0070] Accordingly, although not shown in the drawing, the inside of the first rear surface (120) may further include a driving unit so that the second charging unit (200) connected to the first charging unit (100) can be pulled out or inserted from the first charging unit (100).

[0071] In this way, the smart wired / wireless charger of the present invention and its driving method have the effect of enabling extensive battery remaining capacity management by detecting charging information of another electronic device paired with the electronic device being charged and providing the user with information on whether charging is necessary.

[0072] The smart wired / wireless charger of the present invention and its driving method have the effect of arranging a second charging unit capable of charging a second electronic device inside a first charging unit for charging a first electronic device, and allowing the second charging unit to be withdrawn from the first charging unit according to the remaining battery capacity of the second electronic device, thereby enabling a user to manage the batteries of peripheral electronic devices.

[0073] The smart wired / wireless charger of the present invention and its driving method have the effect of improving the space utilization efficiency of the charger by arranging a moving means between the inner area of ​​the first charging unit and the second charging unit and allowing the second charging unit to be inserted into or withdrawn from the first charging unit as charging is required.

[0074] The smart wired / wireless charger of the present invention and its driving method have the effect of detecting a second electronic device paired with a first electronic device being charged, detecting the remaining battery level of other electronic devices in the vicinity, and managing the battery of an electronic device with a low remaining battery level.

[0075] FIGS. 8 to 11 are exploded perspective views of a second charging unit of a smart wireless charger according to an embodiment of the present invention.

[0076] Referring to FIGS. 8 to 11, the second charging unit (200) of the smart wireless charger (10) of the present invention is a charger that is connected to the first charging unit (100) and can selectively charge as needed.

[0077] The smart wired / wireless charger (10) of the present invention searches for an electronic device paired with a portable terminal (main electronic device) that the user is attempting to charge, obtains information on the remaining battery capacity, and informs the user of this information so that additional charging can be performed.

[0078] As shown in the drawing, the second charging unit (200) includes a second charging body unit consisting of a second front (210), a second side (230), and a second rear (220), and a mounting unit (212) disposed on the second front (210).

[0079] In addition, the smart wired / wireless charger (10) of the present invention may include a charger moving assembly in which a second charging unit (200) is connected to a first charging unit (100) so that charging can be performed on a searched electronic device as needed.

[0080] The charging moving assembly may include a moving bracket (400) and a fixed bracket (500) composed of a moving bracket plate (410) and a moving bracket fastening part (420). As described above, since the second charging unit (200) of the smart wired / wireless charger (10) of the present invention can be inserted into or withdrawn from the first charging unit (100), the second charging unit (200) may further include a driving unit for movement.

[0081] The second charging unit (200) is a device for charging an electronic device paired with a portable terminal or an electronic device located around a smart wired / wireless charger (10), and therefore includes a second charging module (270) composed of a charging coil (272), a charging coil holder (271) for fixing the charging coil (272), and an auxiliary circuit unit (250). The auxiliary circuit unit (250) may include a driving unit that provides power for moving the second charging unit (200) described above.

[0082] As illustrated in Fig. 10, the second charging module (270) may be placed within an auxiliary plate (260) corresponding to the bottom surface of the second charging body part. The auxiliary plate (260) may be fastened in the bottom direction of the second charging body part, which is composed of a second front side (210) and a second rear side (220), to form the bottom surface of the second charging body part.

[0083] The second charging module (270) is mounted on the auxiliary plate (260) so as to correspond to the mounting portion (212) of the second front (210). Although not shown in the drawing, the mounting portion (212) may additionally have a magnet unit arranged to secure an electronic device for charging with magnetic force.

[0084] In addition, a guide protrusion (211) is formed on the second front surface (210) of the second charging unit (200). The guide protrusion (211) is connected to the first guide hole (141g) or the second guide hole (142g) formed on the inner surface of the first charging unit (100) described above, thereby allowing the second charging unit (200) to move in the inner region of the first charging unit (100).

[0085] The second rear surface (220) of the second charging unit (200) has a first fastening hole (220h1) and a second fastening hole (220h2) for fixing the movable bracket (400), and a flexible cable (13) that is fastened to the movable bracket (400) and controls the movement of the fixed bracket (500) is arranged. A cable entry groove (501) is formed in the fixed bracket (500) through which the flexible cable (13) can move freely. 11 and 12, which are illustrated in the drawing but not described, are the first and second fastening screws.

[0086] Accordingly, the fixed bracket (500) can move according to the power provided by the auxiliary circuit unit (250). Since both edges of the fixed bracket (500) are inserted into the connection area of ​​the movable bracket plate (410) and the movable bracket fastening portion (420), the movement defect of the fixed bracket (500) can be reduced.

[0087] The charging moving assembly, which is composed of a moving bracket (400) and a fixed bracket (500), which is composed of a moving bracket plate (410) and a moving bracket fastening portion (420), can be fastened to a first guide hole (141g) or a second guide hole (142g) formed on the inner side of the first charging unit (100). As shown in the drawing, the charging moving assembly is fastened to the guide holes formed on the inner side of the first charging unit (100) while being fixed to the second rear surface (220) of the second charging unit (200), so that the second charging unit (200) can be inserted into or withdrawn from the first charging unit (100).

[0088] In this way, the smart wired / wireless charger of the present invention and its driving method have the effect of enabling extensive battery remaining capacity management by detecting charging information of another electronic device paired with the electronic device being charged and providing the user with information on whether charging is necessary.

[0089] The smart wired / wireless charger of the present invention and its driving method have the effect of arranging a second charging unit capable of charging a second electronic device inside a first charging unit for charging a first electronic device, and allowing the second charging unit to be withdrawn from the first charging unit according to the remaining battery capacity of the second electronic device, thereby enabling a user to manage the batteries of peripheral electronic devices.

[0090] The smart wired / wireless charger of the present invention and its driving method have the effect of improving the space utilization efficiency of the charger by arranging a moving means between the inner area of ​​the first charging unit and the second charging unit and allowing the second charging unit to be inserted into or withdrawn from the first charging unit as charging is required.

[0091] The smart wired / wireless charger of the present invention and its driving method have the effect of detecting a second electronic device paired with a first electronic device being charged, detecting the remaining battery level of other electronic devices in the vicinity, and managing the battery of an electronic device with a low remaining battery level.

[0092] FIG. 12 and FIG. 13 are drawings illustrating a fastening structure of a second charging unit and a movable bracket of a smart wired / wireless charger according to an embodiment of the present invention. FIG. 14 is a drawing illustrating a state in which a movable bracket fastened to a second charging unit of a smart wired / wireless charger according to an embodiment of the present invention moves from a fixed bracket. FIG. 15 is a drawing illustrating a state in which a second charging unit is fastened to a first charging unit of a smart wired / wireless charger according to an embodiment of the present invention.

[0093] Referring to FIGS. 12 to 15, the smart wired / wireless charger (10) of the present invention includes a first charging unit (100), a second charging unit (200), a second charging module (270), and a charging moving assembly. In particular, the main circuit unit (160) may be located on the second rear surface (220) of the second charging unit (200).

[0094] The cable connector (162) drawn out through the second hole (220h2) of the second rear surface (220) is electrically connected to the main board (161). The main circuit unit (160) can be combined with a movable part (600) connected to a movable bracket (400). The movable part (600) includes a connecting movable part (610) connected to the movable bracket (400) and a connector rail part (620) connected to the connecting movable part (610).

[0095] The connecting moving part (610) is connected between the moving bracket plate (410) and the connector rail part (620), and the connecting moving part (610) can move along the connector rail part (620).

[0096] As shown in Fig. 14, the movable bracket (400) is connected to the fixed bracket (500) and can move back and forth in the longitudinal direction of the fixed bracket (500).

[0097] The main board (161) of the main circuit unit (160) is connected to the movable bracket plate (410) and supplies power to the second charging module (270) and the auxiliary circuit unit (250) through the cable connector (162) so that the second charging unit (200) can be inserted into or extracted from the first charging unit (100).

[0098] As illustrated in Fig. 15, the second front (210) and the second rear (220) of the second charging unit (200) are respectively fastened to the first and second guide grooves (141g, 142g) formed on the first inner surface (141) and the second inner surface (142) of the first charging unit (100).

[0099] As described above, since the connecting moving part (610) can move along the connector rail part (620), the second charging part (200) can move along the first and second guide grooves (141g, 142g) of the first and second inner surfaces (141, 142).

[0100] In addition, in the drawing, the main circuit part (160) is shown as being attached to a movable bracket (400) and a fixed bracket (500) placed on the second rear surface (220) of the second charging part (200) and moving together with the second charging part (200), but this is not fixed.

[0101] For example, the main circuit unit (160) may be separated from the second rear surface (220) of the second charging unit (200) and may supply power through a flexible cable (13) or a cable connector (162), and may move the connecting moving unit (610) and the moving bracket (400) to allow the second charging unit (200) to be inserted into or extracted from the first charging unit (100). In this case, the main board (161) of the main circuit unit (160) may be placed within the first front surface (110) or the first rear surface (120) of the first charging unit (100).

[0102] Fig. 16 is a flowchart showing a method for operating a smart wired / wireless charger according to an embodiment of the present invention.

[0103] Referring to FIG. 16, the driving method of the smart wired / wireless charger of the present invention comprises the steps of: (S1601) positioning a first electronic device in a first charging unit; (S1602) searching for an electronic device paired with the first electronic device; (S1603, S1604) determining the searched paired electronic device as a second electronic device and obtaining primary battery information for the second electronic device; (S1605) comparing and determining whether the remaining battery level of the second electronic device is greater than or equal to a preset remaining battery level; (S1606) extracting the second charging unit from the first charging unit and maintaining a charging standby state; (S1607) obtaining secondary battery information for the second electronic device while the second electronic device is removed from the second charging unit; and (S1608) inserting the second charging unit into the first charging unit when the remaining battery level of the second electronic device is greater than or equal to the preset remaining battery level based on the obtained secondary battery information. Includes.

[0104] Here, the first charging unit of the smart wired / wireless charger of the present invention includes a first charging body configured to accommodate a first charging module and a first front and a first rear surface having one side area connected to each other, and the second charging unit includes a second charging body configured to accommodate a second charging module and a second front and a second rear surface having one side area connected to each other, and an auxiliary plate that is connected to the second front and the second rear surface in a state where the second charging module is mounted to form a bottom surface.

[0105] In addition, the charging movement assembly of the smart wireless charger of the present invention includes a movable bracket connected to a second charging unit, and a fixed bracket connected to the movable bracket to guide movement of the second charging unit.

[0106] In addition, the method for driving a smart wired / wireless charger of the present invention determines that the discovered paired electronic device is a second electronic device, and the step of obtaining primary battery information for the second electronic device includes the step of obtaining Bluetooth connection information from the first electronic device; and the step of determining the discovered electronic device as the second electronic device when the acquired Bluetooth connection information matches the discovered electronic device.

[0107] For example, the operating method of the smart wired / wireless charger of the present invention checks a list of electronic devices paired with a first electronic device. In this case, the electronic devices paired with the first electronic device may be considered paired not only if they are connected via Bluetooth, but also if they have exchanged information with each other via wired or wireless means. The description herein is limited to electronic devices paired via Bluetooth.

[0108] The paired electronic device information list may include information on the time of pairing with the first electronic device and the pairing period. The pairing period information may refer to the most recent time the discovered electronic device was paired with the first electronic device. The operating method of the smart wired / wireless charger of the present invention may assign weight to the pairing period information among the pairing period information and the pairing period information.

[0109] That is, in a case where one of the two searched electronic devices has been paired with the first electronic device for a longer period of time but the pairing time is earlier than that of the electronic device with a relatively shorter pairing time, the present invention can preferentially select the electronic device that was paired more recently.

[0110] However, even recently paired electronic devices may be excluded from priority selection if they have been paired for less than the standard pairing period. For example, even recently paired electronic devices may be excluded from priority selection if they have been continuously paired with the primary electronic device for less than 5 minutes.

[0111] Accordingly, the driving method of the smart wired / wireless charger of the present invention can set priorities for electronic devices searched in the order of the electronic devices most recently paired with the first electronic device, when the continuous pairing period is 5 minutes or longer.

[0112] In addition, the method for driving a smart wired / wireless charger of the present invention includes a step of determining whether the remaining battery capacity of the second electronic device is greater than or less than a preset remaining battery capacity value, including a step of determining the remaining battery capacity of the second electronic device in the order in which it was most recently paired with the first electronic device based on acquired Bluetooth connection information.

[0113] In addition, the method for driving a smart wired / wireless charger of the present invention includes a step of withdrawing a second charging unit from a first charging unit and maintaining a charging standby state, a step of displaying a remaining battery capacity of the second electronic device on a display of the first electronic device, and a step of displaying a remaining battery capacity of the second electronic device on the first electronic device while maintaining the second charging unit in the withdrawn state when the remaining battery capacity of the second electronic device is lower than or equal to a preset remaining battery capacity value based on the acquired secondary battery information.

[0114] In addition, in the method for driving a smart wired / wireless charger of the present invention, after acquiring primary battery information for a second electronic device, a reference value of the remaining battery capacity for determining whether charging is necessary may be different from a reference value of the remaining battery capacity for determining whether charging is necessary when secondary battery information is acquired after charging the second electronic device in the second charging unit.

[0115] For example, when a first electronic device is located in a first charging section and charging is in progress, electronic devices paired with the first electronic device are detected, and if the primary battery level of the detected electronic devices is 30% or less, the device can be determined to be a second electronic device. That is, when charging is performed by acquiring primary battery level information for the paired second electronic device, the preset reference value can be set to 30%.

[0116] In addition, when determining whether to continue charging by acquiring secondary battery remaining amount information for the second electronic device after performing a charging operation on the second charging unit for the second electronic device, the withdrawal state of the second charging unit can be maintained when the remaining amount of the battery is 70% or less.

[0117] This is because, when acquiring secondary battery remaining amount information, the second electronic device is installed in the second charging unit and is continuously charging, so the standard for determining whether to charge or not based on the remaining amount of battery of the first second electronic device must be higher than that for determining whether to charge or not, in order to reduce frequent charging operations.

[0118] For example, if the primary battery remaining information obtained among the discovered electronic devices is 20%, the discovered electronic device is determined to be the second electronic device because it is below the preset reference value of 30%. Afterwards, when the second electronic device is placed on the second charging unit and charged together with the first electronic device, if the reference value is set to 30% when determining whether to continue charging the second electronic device, it is determined that the second electronic device, which has been charged to 35%, no longer needs to be charged.

[0119] However, if the remaining battery level of the second electronic device that is being charged is near the set reference value, there is a problem that if charging is stopped according to the 30% reference value, the remaining battery level of the paired second electronic device will soon become an electronic device that needs to be charged.

[0120] In this way, the smart wired / wireless charger of the present invention and its driving method have the effect of enabling extensive battery remaining capacity management by detecting charging information of another electronic device paired with the electronic device being charged and providing the user with information on whether charging is necessary.

[0121] The smart wired / wireless charger of the present invention and its driving method have the effect of arranging a second charging unit capable of charging a second electronic device inside a first charging unit for charging a first electronic device, and allowing the second charging unit to be withdrawn from the first charging unit according to the remaining battery capacity of the second electronic device, thereby enabling a user to manage the batteries of peripheral electronic devices.

[0122] The smart wired / wireless charger of the present invention and its driving method have the effect of improving the space utilization efficiency of the charger by arranging a moving means between the inner area of ​​the first charging unit and the second charging unit and allowing the second charging unit to be inserted into or withdrawn from the first charging unit as charging is required.

[0123] The smart wired / wireless charger of the present invention and its driving method have the effect of detecting a second electronic device paired with a first electronic device being charged, detecting the remaining battery level of other electronic devices in the vicinity, and managing the battery of an electronic device with a low remaining battery level.
