Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. However, the scope of the rights is not limited or limited by these embodiments. Like reference symbols in the drawings denote like elements.

The terms used in the following description are chosen to be generic and universal in the art to which they are related, but other terms may exist depending on the development and / or change in technology, customs, preferences of the technician, and the like. Accordingly, the terminology used in the following description should not be construed as limiting the technical thought, but should be understood in the exemplary language used to describe the embodiments.

Also, in certain cases, there may be a term chosen arbitrarily by the applicant, in which case the meaning of the detailed description in the corresponding description section. Therefore, the term used in the following description should be understood based on the meaning of the term, not the name of a simple term, and the contents throughout the specification.

In the following description, the charging device may refer to a charging station that supplies electric power to an electric device using electricity as a power source. For example, a charging device can use electric power to provide power to electrical devices such as electric vehicles (EVs), electric scooters, and electric kick boards. Illustratively, but not exclusively, the charging device may be implemented in the form of an electric vehicle charging station.

1 illustrates a distributed charging system according to one embodiment. The distributed charging system according to one embodiment includes a central charging device 110 and a sub charging device 120. At least one sub-charging device may be present and illustratively shows five sub-charging devices 121, 122, 123, 124, 125.

The central charging device 110 can regulate the power supplied to the sub-charging device 120. Specifically, 50 kW of power can be supplied when the power required by the first sub-charging device 121 is 50 kW, and 30 kW when the power required by the second sub-charging device 122 is 30 kW. have. In the case where there is no electric power required by the third sub-charging device 123, it may not be supplied.

The central charging device 110 may output a power of 500 kW, for example, and may output power according to the power required by each sub charging device 120.

The power required in each sub-charging device 120 may vary depending on the type of the electric device to be connected or the user's selection. For example, an electric vehicle can be charged with a power of 50 kW, and an electric motorcycle can be charged with a power of 40 kW. Alternatively, it is also possible for the user to select a power of 10 kW or 100 kW in consideration of the charging time. The above numerical values are illustrative and not limiting. In the case of the EV charging standard, the electric power is charged at a power of 50 kW.

In FIG. 1, first, second and fourth sub-charging devices 121, 122 and 124 are connected to an electric vehicle. Each electric car may require different electric power, and may be charged with different electric power according to the user's choice. In some cases, it is also possible to charge with a power of 50 kW.

The distributed charging system is capable of outputting various power using one central charging device 110, so that it is easy to upgrade the system and there is an effect that charging can be performed at a desired speed.

FIG. 2 illustrates a distributed charging system to which a special charging cable, receiving portion and rotating portion according to one embodiment is applied. The distributed charging system according to one embodiment may be configured such that the sub-charging device 210 includes a receiving portion and a rotating portion. The housing portion includes a housing defining a path through which the charging cable is moved, and an opening portion through which the charging cable is discharged to the outside of the housing. Meanwhile, the rotating portion is connected to one end of the receiving portion, and the opening of the receiving portion can be controlled to be rotated along the predetermined direction.

And may include a plurality of receiving portions and rotating portions in one sub-charging device 210, and may include a plurality of charging cables. Or one sub-charging device 210 may be connected for each charging cable.

When the sub-charging device 210 is configured to include the receiving portion and the rotating portion, the charging cable can be easily guided to the electric device 220 to be charged.

FIG. 3A illustrates a power distribution distributed charging apparatus to which a charging connector according to an embodiment is applied. Lt; RTI ID = 0.0 > 310 < / RTI > The sub-charging device may further include a display unit 320 as an example.

The user can select the charging mode from the display portion of the sub-charging device. By way of illustration, but not limitation, the charge mode may be selected from 10 kW, 20 kW, 30 kW, 40 kW, and 50 kW. The higher the charging power, the faster the electric appliance (for example, an electric car) can be charged. On the other hand, as the charging power is lower, the electric device is charged slowly, but there is an effect that the life of the battery can be increased. Therefore, the desired power can be selected for each user, and the charging time is determined according to the selected power. The charging time may also vary depending on the amount of power being charged.

The sub-charging device can supply the charging power differently, and it is also possible to charge the charge per power amount differently depending on the power. For example, a charge of 500 kWh with a power of 50 kW may be less than a charge of 25 kW with a power of 500 kW. Since the time allowed for charging is different for each user, it is possible to charge the user who charges the electric appliance with a small electric power in consideration of the situation of each user.

3B shows another view of the display portion according to one embodiment. In addition, the display unit 330 may display the current state of the battery and the age (or lifetime) of the battery. The state of charge (SOC) of the battery and the age of the battery (SOH) are displayed, thereby informing the user of the charging apparatus of the current charging status of the electric appliance. In particular, by informing the SOH of the battery in the form of age, the user can intuitively understand the SOH, and there is also an effect of inducing low-power charging in the case where it is displayed with a large age.

Referring again to FIG. 3A, there is shown a state in which the charging connector is coupled. The charging connector may be coupled so that the user can perform settlement and charging using the charging connector even if the user does not approach the sub-charging device. Illustratively, but not exclusively, the charging connector may include a display portion, a communication portion, a processor, and may communicate with a cellular phone, a credit card, or the like using the communication portion. The processor may charge a corresponding charge according to a charge rate that can be expressed by the electric power to be charged and a total amount of electric power to be charged, and may perform settlement through the communication unit.

As a result, the user can charge the electric device whose charge rate and charge amount can be adjusted by using the charging device to which the connector is coupled, and there is an effect that the operation is not performed by going to a separate charging device.

4 is a structural view of a dispersion type charging apparatus according to an embodiment. The distributed charging apparatus according to one embodiment may be composed of a center charging apparatus and at least one sub-charging apparatus. The central charging apparatus may include a control unit 410 and the sub-charging apparatus may include an output unit 420 and a sensor unit 430.

The control unit 410 is located in the central charging unit and can adjust the power output to each sub charging unit. As described above with reference to FIG. 1, different sub-charging devices may require different powers, and the control section of the central charging device distributes the power in response to the request.

For example, when the first sub-charging device requires 30 kW and the second sub-charging device requires 70 kW, the central charging device can send 30 kW and 70 kW to each of the first and second sub charging devices corresponding to each power.

Each sub-charging device may include an output unit 420 and a sensor unit 430, and the output unit 420 may be connected to an electric device to be charged to supply electric power. The sensor unit 430 may measure the SOC and / or the SOH of the electrical equipment to be charged. The measuring method may be a method using the supplied voltage and current, but the present invention is not limited thereto and in some cases it is also possible to receive the information from the electric device.

It is possible to display the SOC and the SOH to be sensed when the sub-charging apparatus further includes the display unit, and to display the charging power. Or a display portion may be included and displayed in the central heavy equipment or the charge connector.

5 is a charge flow diagram using a distributed charging apparatus according to one embodiment. The charging process of the distributed charging apparatus according to an exemplary embodiment includes connecting a sub-charging apparatus 510, checking SOC and SOH 520, selecting charging time and output 530, (Step 540) and step 550 (step 550).

In a step 510 of connecting the sub-charging device, the electric device to be charged is connected to the sub-charging device. It is possible to connect the charging connector by connecting it, but it is also possible to connect it directly to the electric appliance without connecting a separate charging connector.

When the sub-charging device and the electric device are connected, the sub-charging device can sense the state of charge (SOC) and the state of health (SOH) of the electric device. Accordingly, the user can confirm (520) the SOC and SOH that the sub-charging device is sensing.

Next, the charging time and the output are selected (step 530). Since the charging apparatus can set the charging power and the power amount differently, the user can set the corresponding item. Specifically, the output may mean the output power of the sub-charging device, and the charging time may be the time taken to charge the total amount of power corresponding to the output power. Therefore, the power and the amount of electric power can be determined when the charging time and the output are selected. However, this is only an example, and the user can directly select the power and electric energy item.

After that, the bill payment step 540 is performed. The user uses the communication unit to determine the charge of the power amount. The charge rate of the electric device can be varied depending on the electric power and the electric power amount.

Basically, it can be charged to the charge according to the amount of electric power, but when it is charged with low power, it takes a long time, so a certain amount of money can be discounted. Conversely, when charging with high power, it takes a little time, so a certain amount of money may be increased. In some cases, there may be no difference in charge per watt.

For example, when a distributed charging device is installed in a parking lot of a mart, a user may not be able to quickly charge the battery due to frequent visits to the battery, and it is also possible to protect the battery SOH while charging for a long time.

Finally, in the charging step 550, power supplied from the central charging device is delivered to the electrical device to be charged through the sub-charging device. Charging can be performed after selection and settlement of the charging power and the amount of power have been completed. However, it should be understood that the above-described exemplary embodiments are illustrative, and that the present invention can be embodied in various other forms without departing from the scope of the present invention.
