Description

Power supply device, method, and program for analyzing power specifications of connected electronic device

Technical Field

The present invention relates to a power supply apparatus, method, and program based on power specification analysis of a connected electronic device, and in particular, to a power supply system that recognizes a connected electronic device to supply battery charging power or driving power, recognizes a specification voltage of the connected electronic device, and can supply power at the recognized specification voltage.

Background

With the development of electronic products, various types of electronic products have been used in real life. Such electronic products can be broadly classified into wireless-type and wired-type electronic products.

The wireless electronic product is internally equipped with a separate power supply device such as a battery, and is driven by receiving power from the internal power supply device. As such a battery, a lithium ion (Li-ion) battery, a nickel hydrogen (Ni-MH) battery, or the like is used. The maximum current amount allowed in the range where no damage occurs varies depending on the type and capacity of the battery and the standard voltage required for charging. Thus, a separate dedicated charger is used in each electronic product.

Further, the wired electronic product receives driving power from a power source (for example, a socket or the like) through a power supply cable, and a dedicated power supply cable for the electronic product is used because a voltage and a current required for the electronic product are different.

With the production of a very large number of chargers and power supply cables, there occur problems of the burden of consumers who purchase these chargers and power supply cables separately, the cost required to discard these chargers and power supply cables, and the increase in environmental pollution.

Further, even if the voltage and current which can be supplied are within the allowable range where they can be mixed, the terminal and the terminal to be connected are different in form from each other depending on the charger or the power supply cable, and thus, it is difficult to mix them with each other, and thus, there is an inconvenience that the user needs to hold all the chargers and the power supply cables separately.

Also, although the voltage and current that can be supplied are different, the terminal and the terminal form are the same, and thus a case may occur in which users mix them for use. In this case, a problem of damage to the electronic product or the battery of the electronic product may occur.

1. For the basis bookDescription of the constitution of the electric Power supply System of the embodiment of the invention

The power supply system according to an embodiment of the present invention includes a power supply device, an extension cable 510, a connection joint 520, and a direct connection kit 530. The power supply device may include a pre-voltage charger 100, a pre-voltage adapter 200, and a pre-voltage battery 300.

Referring to fig. 1, a pre-voltage charger 100, an extension cable 510, a connection terminal 520, and a direct connection kit 530 are shown.

Referring to fig. 2, a pre-voltage charger 100, a pre-voltage adapter 200, and a pre-voltage battery 300 are shown.

Referring again to fig. 1, the pre-voltage charger 100 has a power connection terminal (not shown) and an output terminal 120.

The power supply connection terminal (not shown) is connected to a conventional adapter, and receives power from the adapter. The conventional adapter converts ac power of the power supply into dc power and supplies the dc power to the pre-voltage charger 100. For example, terminals using an adapter of DC (Direct Current) system including the conventional PD (Power Delivery) system, QC (Quick Charge) system, and the like may be coupled to the power supply connection terminals. In an embodiment, existing adapter terminals may include USB-A type, USB-B type, USB-C type, etc.

Therefore, the power supply connection terminals may be formed in a plurality of different forms from each other. In an embodiment not shown, the power connection terminal may be formed at the opposite side of the output terminal 120.

The values of the voltage and the current that can be supplied by the DC system such as PD and QC are different from each other, and the pre-voltage charger 100 can change the voltage of the power supplied from the existing adapter terminal to match the connected electronic device by lowering or raising the voltage.

For example, in the case where the electric power input by the PD method is 12V and 3A, the pre-voltage charger 100 may boost (exceed 12V) to match the electronic device connected through the output terminal 120 and supply it to the electronic device.

The output terminal 120 is electrically connected to the electronic device via an extension cable 510.

Connection terminals 511 and 512 for electrical connection are formed at both ends of the extension cable 510, respectively. Among the connection terminals, the connection terminal 511 disposed at the opposite side of the pre-voltage charger 100 is detachably coupled with a plurality of connection terminals 520 having shapes different from each other.

In the illustrated embodiment, the plurality of connection joints 520 include a Lightning (Lightning) connection joint 521, a C-connection joint 522, a DC charging connection joint 523, a notebook computer connection joint 524, an unmanned aerial vehicle connection joint 525, and an electric drill connection joint 526. In an embodiment not shown, the plurality of connection tabs 520 may be formed in a shape corresponding to terminals of various electronic devices.

That is, each connection tab 520 is formed to have a shape corresponding to the shape of a terminal formed at the electronic device. For example, in the case of bonding the lightning connection terminal 521 to the connection terminal 511, the lightning connection terminal 521 may be connected to an electronic device equipped with a lightning terminal in a product produced by apple corporation.

Since the connection terminal 520 and the connection terminal 511 are detachably configured, it is possible to supply power by being electrically connected to various electronic devices by providing one extension cable 510 and one set of connection terminals 520.

However, the connection terminal 511 and the connection tab 520 are not limited thereto and may be integrally formed.

In the illustrated embodiment, the connection terminals 511 and the connection joints 520 and the connection terminals 512 and the output terminals 120 may be detachably coupled by magnetism.

The direct connection set 530 includes a terminal (not shown) that is electrically coupled to the output terminal 120 of the pre-voltage charger 100, and a receiving groove that can be coupled to a power supply is formed in a recess in one side surface thereof.

The accommodating groove accommodates at least a part of the battery and is formed in a shape matching with the accommodated part of the battery. In the state where the battery is coupled, a terminal in a form corresponding to the charging terminal of the battery is formed at a portion facing the charging terminal of the battery in the portion of the housing groove. And, in a state where the battery is incorporated, the two terminals are in contact with each other.

Thus, the power supply and the battery are electrically connectable through the conventional adapter 10, the pre-voltage charger 100, and the direct connection kit 530.

In an embodiment not shown, the direct connection kit 530 is not connected in direct contact with the output terminal 120, but may be connected with the output terminal 120 through the extension cable 510.

Referring to fig. 1, there is shown a pre-voltage terminal 20 that can be used for connection terminals 511 and 512 of extension cable 510, output terminal 120 of pre-voltage charger 100, output terminal 220 of pre-voltage adapter 200 (see fig. 4), and output terminal 320 of pre-voltage battery 300 (see fig. 9).

The pre-voltage terminal 20 includes at least three electrodes spaced apart from each other. The three poles correspond to +electrodes, -electrodes, and product analysis electrodes, respectively, the +electrodes and the-electrodes serving as channels through which current flows in the case where power is supplied to the electronic device by the power supply. The product analysis electrode is used as a channel for micro-current transmitted from the pre-voltage charger 100, the pre-voltage adapter 200, and the pre-voltage battery 300 to grasp characteristics of the electronic device (based on whether the battery is driven or not, the specification voltage, the specification current, and the like).

And, a data transmission electrode for transmitting data may be included. However, not limited thereto, four or more electrodes may be used for the pre-voltage terminal 20.

Also, the pre-voltage terminal 20 may include a processor for controlling the pre-voltage charger 100, the pre-voltage adapter 200, and the pre-voltage battery 300.

In fig. 1, the pre-voltage terminal 20 is shown to have a spring pin shape including magnetism, but the shape of the pre-voltage terminal 20 is not limited thereto. For example, the pre-voltage terminal 20 may have a USB-C type shape. Whether or not to function as the pre-voltage terminal 20 is determined not by the shape of the terminal but by a processor controlling the pre-voltage charger 100, the pre-voltage adapter 200, and the pre-voltage battery 300 including the pre-voltage terminal 20.

Referring to fig. 3, a specific voltage and current supplied through the existing adapter 10 are deformed at the pre-voltage charger 100 and supplied to respective electronic devices through the extension cable 510.

That is, the pre-voltage charger 100 determines whether each electronic device is a battery type driven by battery charging and a continuous power type driven by continuous power supply, and supplies deformed power according to the determined types.

In the case of the battery type, the electronic device may include a battery, which is stored therein and driven based on the battery.

In the case of the battery type, the pre-voltage charger 100 grasps the charging voltage of the electronic device, and converts the electric power supplied from the power source into electric power equipped with the charging voltage to supply the electric power to the electronic device. For example, a camera or drone, etc. may correspond to a battery type.

In the case of the continuous power type, the pre-voltage charger 100 grasps the specification voltage and the specification current of the electronic device, and converts the power supplied from the power source into the power provided with the specification voltage and the specification current to supply the power to the electronic device. For example, a notebook computer or the like may correspond to a continuous power type.

In addition to the pre-voltage charger 100, electric power deformed according to the type of electronic device connected through the pre-voltage adapter 200 and the pre-voltage battery 300 may be supplied.

Thus, the power supply system according to the embodiment of the present invention can supply power deformed according to the type of each electronic device without a dedicated charger or a dedicated power supply cable.

The configuration of the power supply system will be described in more detail below with reference to fig. 4 to 6.

Description of the Pre-Voltage charger 100

Referring to fig. 4 and 5, the pre-voltage charger 100 includes a power connection terminal 110, an output terminal 120, a display unit 130, a processor 140, a supply mode determination unit 141, an output type analysis unit 142, and a transformation unit 143. The various components of the pre-voltage charger 100 may be controlled by the processor 140.

In an embodiment not shown, the pre-voltage charger 100 may include an LED section instead of the display section 130.

The pre-voltage charger 100 has a case forming an external appearance thereof. As shown in fig. 2, the housing may be formed in a hexahedral shape with a part of the shape being formed into a curved surface. However, the present invention is not limited thereto, and may be formed in various forms.

At least one power connection terminal 110 and at least one output terminal 120 are formed at the outer circumferential surface of the case.

The power supply connection terminal 110 is formed to be capable of being coupled to the conventional adapter 10, and the output terminal 120 may be the pre-voltage terminal 20.

In an embodiment, the output terminals 121, 122, 123 may all be the pre-voltage terminal 20, or some of the output terminals 121, 122 may be the pre-voltage terminal 20 and the remaining terminals 123 may be existing terminals such as USB-C type terminals.

However, not limited thereto, the output terminal 120 may be provided as four or more. Also, at least one of the output terminals 120 may be implemented as the pre-voltage terminal 20 and the remaining output terminals may be implemented as existing terminals.

A display 130 is formed on the outer peripheral surface of the case. The display part 130 may display the types (PD, QC, etc.) of terminals connected to the power connection terminal 110. Further, the display portion 130 may display the type of device (an adapter, an auxiliary battery, etc.) connected to the power connection terminal 110.

Also, an executable mode performed on the output terminal 120 based on the electric power input from the connected terminal may be displayed. The pre-voltage charger 100 may provide a battery charging mode and a continuous power supply mode through the output terminal 120. The processor 140 controls the supply mode judging section 141 to judge the executable mode based on the inputted power, and controls the display section 130 to display the judged executable mode in a visually identifiable form.

Further, the processor 140 controls the display unit 130 to display at least one of the specification voltage of the electronic device connected to the output terminal 120, the voltage/current of the power supplied to the connected electronic device, and the charge level of the connected battery in a visually recognizable form.

And, the processor 140 controls the output type analysis part 142 to transmit the micro current to the connected electronic device to judge the power supply type and the power supply specification of the corresponding electronic device.

The power supply type is classified into a battery type and a continuous power type. In the case where the electronic device is of a battery type, the power supply specification includes information about the charging voltage. In the case of a continuous power type, the power supply specification includes information about a specification voltage and a specification current.

At least one of the connection terminal 520, the direct connection kit 53, and the electronic device may include a transformation control printed circuit board including information about a power supply type and a power supply specification of the electronic device.

The processor 140 controls the output type analysis part 142 to transmit the micro-current to the variable voltage control printed circuit board to identify information about the power supply type and the power supply specification.

The processor 140 controls the transforming part 143 to convert the power received from the power source based on the identified power supply type and power supply specification and transmit it to the electronic device.

The processor 140 is housed in the casing, and the processor 140 is electrically connected to each component of the pre-voltage charger 100. In an embodiment, the processor 140 may be implemented by a Printed Circuit Board (PCB), a microcomputer, including elements for performing the functions of the pre-voltage charger 100. However, it is not limited thereto.

In an embodiment, the output terminal 120 of the pre-voltage charger 100 may be implemented by the pre-voltage terminal 20.

Referring to fig. 6, the configuration of the pre-voltage terminal 20 is shown. The pre-voltage terminal 20 may be provided with a plurality of electrodes 21 and a processor 22. The shape of the pre-voltage terminal 20 is not limited to fig. 1, and for example, the pre-voltage terminal 20 may have a USB-C type shape.

In one embodiment, the processor 140 of the pre-voltage charger 100 may be implemented by the processor 22 of the pre-voltage terminal 20. In this case, the respective components of the pre-voltage charger 100 may be controlled by the processor 22 of the pre-voltage terminal 20. Processor 22 may perform at least a portion of the functions of processor 140.

Description of Pre-Voltage adapter 200 and Pre-Voltage Battery 300

Referring to fig. 7 and 8, a pre-voltage adapter 200 and a pre-voltage battery 300 are shown.

The pre-voltage adapter 200 differs from the pre-voltage charger 100 as follows.

The pre-voltage adapter 200 does not receive dc power from the existing adapter 10, but directly receives ac power from an ac power source (220V, 110V).

The electronic device is connected to a power supply through a pre-voltage adapter 200 and an extension cable 510.

The power connection terminal 110 is formed in the pre-voltage charger 100, and the plug 210 is formed in the pre-voltage adapter 200 instead of the power connection terminal 110.

The pre-voltage adapter 200 is coupled directly to the receptacle via the plug 210 and receives power directly from the ac power source (220V, 110V).

That is, the pre-voltage adapter 200 supplies the power received from the ac power source (220V, 110V) by reducing the voltage to the charging voltage of the connected battery and the standard voltage of the electronic device.

In contrast, the pre-voltage charger 100 differs as follows: the power received through the existing adapter 10 is supplied by being stepped up or down to the charging voltage of the connected battery and the specification voltage of the electronic device.

Further, since the pre-voltage charger 100 receives limited power from the existing adapter, the executable mode is determined and displayed, whereas since the pre-voltage adapter 200 directly receives power, the supply mode determining section is not included.

Except for this difference, the output type analysis section 242, the transformation section 243, and the output terminal 220 of the pre-voltage adapter 200 may be configured identically to the output type analysis section 142, the transformation section 243, and the output terminal 120 of the pre-voltage charger 100.

Also, the pre-voltage battery 300 is different from the pre-voltage charger 100 in the following points.

Referring to fig. 12, the pre-voltage battery 300 further includes a power storage part 350.

The pre-voltage battery 300 may convert the power supplied through the power connection terminal 310 into a charging voltage of the power storage part 350 to charge the power storage part 350.

In addition, when the pre-voltage battery 300 is connected to the electronic device through the output terminal 320, the pre-voltage battery 300 supplies power to the electronic device using the power storage unit 350 as a power source, instead of supplying power to the electronic device using external power as a power source.

The supply mode determination section 141, the output type analysis section 142, the transformation section 143, and the output terminal 120 of the pre-voltage charger 100 analyze the electronic device with the power supplied from the outside and supply the power.

In contrast, the supply mode determination unit 341, the output type analysis unit 342, the transformation unit 343, and the output terminal 320 of the pre-voltage battery 300 analyze the electronic device using the power storage unit 350 as a power source and supply power.

Except for this difference, the supply mode judging part 341, the output type analyzing part 342, the transforming part 343, and the output terminal 320 of the pre-voltage battery 300 may be configured identically to the pre-voltage charger 100 and the supply mode judging part 141, the output type analyzing part 142, the transforming part 143, and the output terminal 120.

2. Description of the power supply method according to the embodiment of the invention

Hereinafter, a power supply method according to an embodiment of the present invention will be described with reference to fig. 9 to 13.

Referring to fig. 9, the power supply apparatus 100, 200, 300 receives power from a power source (S10). In the case of the pre-voltage charger 100, dc power is received, in the case of the pre-voltage adapter 200, ac power is received, and in the case of the pre-voltage battery 300, power is received from the built-in power storage unit 350.

When power is supplied from the power source, the power supply apparatus 100, 300 determines an executable mode based on the received power, and displays the determined mode (S20).

Referring to fig. 10, an embodiment of step S20 is shown.

The processor 140, 340 of the power supply device 100, 300 controls the supply mode determining section 141, 341 to compare the power received from the power source with the reference power set in advance (S21).

When the reference power is smaller than the received power, the processor 140, 340 controls the supply mode determination unit 141, 341 to determine the battery charging mode and the continuous power supply mode as executable modes (S22).

When the reference power is larger than the received power, the processor 140, 340 controls the supply mode determination section 141, 341 to determine only the battery charging mode as the executable mode (S23).

Continuous power supply requires relatively more power than battery charging. In the case where the power received from the power source is insufficient for the continuous power supply, since the continuous power supply is limited, the power supply apparatus 100, 300 judges the limitation in advance and displays the limitation in a manner recognizable to the user.

For example, in the case where the continuous power required to operate the notebook computer is 40W, the continuous power supply mode may be limited, as compared with the case where the power of 15W is supplied from the adapter of the QC mode. In contrast, in the case of supplying 60W of power from the PD-mode adapter, both the battery charging mode and the continuous power supply mode may be executed.

Referring to fig. 11, another embodiment of step S20 is shown.

The processor 140, 340 of the power supply device 100, 300 controls the supply mode judging section 141, 341 to compare a value obtained by dividing the power received from the power source by the number of the output terminals 120, 320 with a preset reference power.

In the case where the reference power is smaller than the value obtained by dividing the received power by the number of output terminals, the processor 140, 340 controls the supply mode determining section 141, 341 to determine that the battery charging mode and the continuous power supply mode can be performed at the respective output terminals (S25).

In the case where the reference power is greater than the value obtained by dividing the received power by the number of output terminals, the processor 140, 340 controls the supply mode determining section 141, 341 to determine that only the battery charging mode is executable at each output terminal (S26).

The output terminals 120, 320 may be provided in plural, and the received power may be divided and distributed by the output terminals 120, 320, and then the executable mode may be determined by the respective output terminals 120, 320.

However, without being limited thereto, as in the embodiment described with reference to fig. 10, the executable mode may be determined irrespective of the number of output terminals 120, 320.

Referring again to fig. 9, the power supply apparatuses 100, 200, 300 are connected to the electronic device (S30). The power supply device 100, 200, 300 may be electrically connected to the electronic apparatus through the extension cable 510. The power supply device 100, 200, 300 may be electrically connected to the electronic device through the connection connector 520 or the direct connection type connection set 530 by the extension cable 510, or may be electrically connected to the electronic device not through the extension cable 510 but through the direct connection type connection set 530. Here, the electronic device connected by the extension cable 510 may be a battery. When connected to the electronic device, the power supply apparatus 100, 200, 300 determines the power supply type and power supply specification of the connected electronic device (S40).

The processor 140, 240, 340 controls the output type judging part 142, 242, 342 to transmit the micro current to the connected electronic device, the connection joint 520 or the direct connection type connection kit 530, thereby judging the power supply type of the corresponding electronic device (S41).

In the case where the power supply type is the battery type, the processor 140, 240, 340 judges the charging voltage of the electronic device by the micro-current transmitted by the output type judging part 142, 242, 342 (S42). In the case of a battery type, the power supply specification includes information about the charging voltage.

The processor 140, 240, 340 controls the output type determining section 142, 242, 342 to derive the maximum supply current based on the power received from the power supply and the charging voltage (S43).

In an embodiment, the maximum supply current may be derived by dividing the power received from the power supply by the charging voltage.

Also, in another embodiment, in the case where the power received from the power supply is distributed by the output terminals 120, 220, 320, the maximum supply current may be derived by dividing a value obtained by dividing the power received from the power supply by the number of terminals by the charging voltage.

When the maximum supply current is derived, the processor 140, 240, 340 controls the output type determining section 142, 242, 342 to compare the maximum supply current with a preset reference supply current (S44). The preset reference supply current may be set to a value for supporting quick charge within a range that does not damage the battery.

In the case where the derived maximum supply current is smaller than the reference supply current, the processor 140, 240, 340 controls the output type determining section 142, 242, 342 to set the maximum supply current as the battery supply current (S45).

In the case where the derived maximum supply current is greater than the reference supply current, the processor 140, 240, 340 controls the output type determining part 142, 242, 342 to set the reference supply current as the battery supply current (S46).

In the case where the power supply type is the continuous power type, the processor 140, 240, 340 judges the specification voltage and the specification current of the electronic device by the micro-current transmitted by the output type judging part 142, 242, 342 (S47). In the case of a continuous power type, the power supply specification includes information about a specification voltage and a specification current.

The micro-current returned to the power supply apparatus 100, 200, 300 through the transformation control printed circuit board included in the interior of at least one of the connection terminals 520, 530 and the electronic device may be analyzed to acquire information about the power supply type and the power supply specification.

Referring again to fig. 9, the power supply apparatus 100, 200, 300 transforms the received power based on the determined power supply type and power supply specification, and transmits it to the electronic device (S50).

In the case of a battery type, electric power equipped with a charging voltage and a battery supply current is supplied to an electronic device.

In the case of the continuous power type, power equipped with a specification voltage and a specification current is supplied to the electronic device.

When power is supplied to the electronic device through one of the output terminals 120, 220, 320, the power supply apparatus 100, 300 judges an executable mode for the output terminal 120, 320 in the non-operating state and displays the executable mode (S60).

For example, in the case where continuous power of 30W is transmitted through the first output terminals 121, 321 and the power received from the power source is 50W, the power supply device 100, 300 determines the executable mode based on the remaining 20W and displays the executable mode.

Referring to fig. 13, the process of step S60 is shown.

First, the processor 140, 340 controls the supply mode determination section 141, 341 to derive a difference value obtained by subtracting the power of the output terminal in the operation state from the power received from the power supply (S61).

When the difference value is derived, the processor 140, 340 controls the supply mode determination section 141, 341 to compare the difference value with a preset reference power (S62).

When the reference power is smaller than the difference value, the processor 140, 340 controls the supply mode determination section 141, 341 to determine that the battery charging mode and the continuous power supply mode can be performed at the output terminal in the non-operating state (S63).

In the case where the reference power is greater than the difference value, the processor 140, 340 controls the supply mode determination section 141, 341 to determine that the output terminal in the non-operating state can perform only the battery charging mode (S64).

If there are remaining output terminals 120, 320 in the non-operating state, steps S30, S40, S50, and S60 may be repeatedly performed.

While the embodiments of the present invention have been described above with reference to the drawings, those skilled in the art to which the present invention pertains will appreciate that the present invention may be embodied in other specific forms without changing the technical spirit or essential features of the present invention. Accordingly, it should be understood that the above-described embodiments are illustrative in all respects, rather than restrictive.
