Description

{Movable apparatus for battery charging of electric vehicle}

The present invention relates to a charging device for a mobile electric vehicle, and more particularly, to a charging device for a mobile electric vehicle that can be used outdoors.

Electric vehicles (EV) are cars that run on electricity. Specifically, they can be divided into pure electric vehicles that run solely on electricity and hybrid electric vehicles that run on fossil fuels and electricity.

Generally, purely electric vehicles are called electric vehicles, and hybrid electric vehicles are those that run on electricity and fossil fuels as mentioned above.

Therefore, electric vehicles must be equipped with a battery that supplies electricity for driving, and in the case of plug-in hybrid electric vehicles, the battery can also be charged by current supplied from an external power source.

Meanwhile, the charging method of electric vehicles can be divided into rapid charging and slow charging depending on the charging time. In this case, rapid charging is a form in which the battery is charged by direct current supplied from the charger, and in the case of slow charging, the battery is charged by alternating current supplied to the charger.

Chargers like the above are usually one of the important infrastructures for the popularization of electric vehicles, and are usually installed as fixed units in some areas of underground parking lots in apartment complexes, department stores, and large marts.

With the above method, only electric vehicles can be parked in the parking lot, but there are cases where electric vehicles that need to be charged cannot be charged because general vehicles are parked there, and the number of chargers currently installed in Korea is somewhat difficult to cope with as the number of electric vehicles continues to increase.

To overcome the above-mentioned shortcomings, various configurations of mobile charging devices have been proposed. For example, a mobile device for an electric vehicle charging device disclosed in Patent Publication No. 2020-0002165 can be cited, which allows the user to easily move the charging device for charging an electric vehicle to a desired location.

The above invention is characterized by moving the charger near an electric vehicle that needs to be charged, so it has the advantage of being able to charge an electric vehicle in a relatively wide parking area, but has the disadvantage of requiring a separate rail for transporting the charger and also requiring somewhat complicated power supply wiring .

A charging device (100) for a mobile electric vehicle according to the present invention is configured to include a station (10) in the shape of a square box and a plurality of charging packs (70) that are stored and charged in a space formed inside the station (10), as shown in FIG. 1.

The above station (10) is configured to be mobile and, when placed in a specific location, is configured to operate simply by connecting power from the outside.

The external power source connected to the above station (10) can use a general commercial power source, but if a commercial power source is not configured, it can be implemented using a self-charging device using wind power, solar power, etc., and if necessary, it can be configured by mixing a commercial power source and a self-charging device.

And the charging pack (70) is loaded and charged inside the station (10), taken out to charge an electric vehicle, and when charging is complete, it is brought into the station (10) and stored.

First, the charging pack (70) is configured to have a size and weight that a user can take out from the station (10) and carry by hand, and as illustrated in FIG. 2, it comprises a body (71) having a space formed therein for accommodating components, a battery (72) accommodated inside the body (71), a moving wheel (73) formed at the bottom of the body (71), a handle (74) attached to the side of the body (71), a connection part (80) formed on the outer surface of the body (71) and connected to the battery of an electric vehicle, an internal connection part (85) formed on one surface of the body (71) and used to charge the battery (72) by power from the station (10), and a control module (90) for outputting and controlling the status of the entire charging pack (70).

The above body (71) is advantageously configured in the form of a square box in terms of being stored inside the station (10), and in particular, it is preferable that the handle (74) be configured in a form that is secured inside the square box during storage and extends to the outside during use.

If necessary, the handle (74) may be configured to be rotatable when fully extended outward, and the above configuration has the advantage of providing convenience of operation when the user moves the charging pack (70).

The above battery (72) is placed inside the body (71) and is appropriately fixed so that shaking due to movement does not occur.

The above connection part (80) is configured to correspond to the charging standard required for connection with the battery (72) and the battery of the electric vehicle, and is configured to include a power supply part (81) for connecting power and a signal part (82) for connecting signals.

The above internal connection part (85) is configured for connecting the charging power supplied from the station (10) when the charging pack (70) is stored inside the station (10).

The above internal connection part (85) can be configured to be connected to the station (10) in a contact manner rather than a plug manner, and, if necessary, can be configured in a form in which different poles contact each side of the body (71).

In addition, the internal connection part (85) may be configured to protrude outward only when charging while stored in the station (10) and to be automatically sealed when taken out from the station (10), and such a configuration has the effect of preventing risks in advance when taken out.

Meanwhile, the control module (90), as shown in FIG. 3, includes an output unit (91) that outputs information and an input unit (92) that a user inputs, receives and transmits necessary signals through the signal unit (82), and is connected to the battery (72) to recognize status information of the battery (72) and control charging operations, etc., and also controls power disconnection when fully charged at the station (10) through the internal connection unit (85).

That is, it controls the charging and discharging of the battery (72) and outputs status information of the battery (72) when necessary.

Of course, if necessary, information such as usage status, usage history, and user information can be stored separately.

The user can easily move the charging pack (70) from the station (10) to the car using the handle (74) and the moving wheel (73), and when charging is complete, can easily move it back to the station (10).

That is, as shown in Fig. 4, the handle (74) is stored while inserted into the body (71), and when moving as a charging vehicle, the handle (74) protrudes and is operated by moving using the moving wheel (73).

Of course, if necessary, the bottom of the body (71) may be configured to include a support member (75) opposite the moving wheel (73) so that the body (71) can be supported vertically when stopped.

The above charging pack (70) is preferably set to a size of approximately ±20% of 600 mm x 1200 mm x 500 mm in consideration of movement and charging level, but if necessary, it can be implemented in a size other than the above that can be hand-carried.

Additionally, it can be manufactured in various sizes depending on the intended use.

Meanwhile, the station (10) has a function of storing and charging the charging pack (70) inside and automatically performing the loading and unloading of the charging pack (70), and as shown in Fig. 1, it is configured to include a casing (11) having a rectangular box shape in appearance, an outlet (12) formed on the side of the casing (11), an inlet (13) formed at a position corresponding to the outlet (12), and a control unit (60) installed on one side.

It is preferable that the above casing (11) be configured in a square shape, and it is also preferable that the overall size be set similar to that of a general container, which is advantageous for movement and installation.

Of course, if necessary, the casing (11) may be configured in a small size that can accommodate up to 10 charging packs (70), and the height of the casing (11) may also be configured in a size smaller than that of a typical container. In addition, if necessary, it may be configured in a relatively larger form than a typical container.

In particular, if the above station (10) accommodates less than 10 charging packs (70), it can be configured in a small size and implemented in a form that can perform charging on a highway using a separate mobile vehicle.

That is, when there is a request for electric vehicle charging on a highway, a small station (10) can be moved to the location using a mobile vehicle such as a truck to proceed with charging.

At this time, the vehicle is equipped with a charging pack station (10), moves to the requested location, delivers the charging pack (70), and when charging is complete, retrieves the charging pack (70).

And the size of the station (10) mounted on the vehicle and the capacity and size of the charging pack (70) can be implemented in various ways.

And the above discharge port (12) is where the charging pack (70) is discharged. If necessary, a stand is installed at the entrance to provide convenience in discharge to the outside.

The above inlet (13) is where used charging packs (70) are brought into the station (10), and a stand can also be installed at the inlet.

Of course, the above outlet (12) and inlet (13) may include doors that can be opened and closed manually or automatically.

Meanwhile, the charging pack (70) is coupled to a moving body (20) as shown in FIG. 5 and moves inside the station (10).

That is, it is placed and connected to the upper part of the moving body (20) at the inner end of the outlet (12), and the user detaches the charging pack (70) connected to the moving body (20) and takes it out. Conversely, when bringing it in, the charging pack (70) is installed on the upper part of the moving body (20) placed at the end of the inlet (13).

The above moving body (20) is configured to include a first driving wheel (21) and a second driving wheel (22) that are formed protruding on each side of a moving body (24) in the shape of a square plate.

Additionally, each drive wheel is located within the moving body (24) when not in operation, and protrudes outward only when in operation.

And after protruding, it is configured to move downward a certain distance so that the left/right/front/backward direction changes can be performed immediately.

That is, as shown in Fig. 6, the moving body (20) moves in each direction with the driving wheels protruding outward.

The above driving wheels are configured to include separate driving units inside to drive the wheels and control the position of the wheels.

In addition, the first driving wheel (21), the second driving wheel (22), or both may be configured to include a function capable of transmitting electricity by being composed of a conductive material that can be connected to a power source when connected externally.

Additionally, the above-mentioned mobile body (20) includes a mobile battery (25) for driving inside.

Here, the mobile battery (25) supplies power to the driving wheels, and furthermore, the mobile battery (25) is configured to be electrically connected to the first driving wheel (21) or the second driving wheel (23) so that it can be charged by an external power source.

In addition, the above-described mobile body (20) includes a movement control unit (26), and the movement control unit (26) controls the operation of the driving wheel and also includes a function of performing wireless communication with the control unit (60), so that the movement position, etc. can be controlled by the control unit (60).

In addition, the above-mentioned moving body (20) includes a configuration for fixing the charging pack (70) to the upper part, and includes a connecting port (27) for electrical connection with the internal connecting portion (85) of the charging pack (70) and the first driving wheel (21) or the second driving wheel (23).

If necessary, the above-mentioned connecting port (27) can be configured to be electrically connected to the above-mentioned mobile battery (25) so that the above-mentioned mobile battery (25) can be charged by the above-mentioned charging pack (70).

The above-mentioned mobile body (20) and charging pack (70) are stored and charged as a set inside the station (10).

Meanwhile, the station (10) includes a loading module (30) that is placed at a specific location as the moving body (20) moves.

That is, the moving body (20) is configured to move only in the loading module (30) and does not detach from the loading module (30).

Accordingly, the loading module (30) is configured in a frame shape that is connected in the forward/backward/left/right/up/down directions, as shown in Fig. 7, and cells are formed between the frames in which a unit moving body (20) can be placed.

The number of cells in the above Fig. 7 is 4*5*3=60, but this is an example and a different number of cells is formed considering the actual size.

In the above loading module (30), the unit cell is configured to include a first rail (31) in the forward-backward direction, a second rail (32) in the left-right direction, and a vertical pillar (33) in the up-down direction. The first rail (31) and the second rail (32) can be configured to include a horizontal portion and a protrusion that protrudes vertically from the horizontal portion as shown in Fig. 8, and the protrusion is removed at the intersection to prevent interference during movement.

In addition, the height of the above protrusion is formed smaller than the downward movement length of the first driving wheel (21) and the second driving wheel (22) to prevent interference.

The above vertical column (33) is illustrated as having a square cross-section, but can be implemented in other cross-section shapes and performs the function of supporting the entire loading module (30).

As shown in Fig. 9, the above-mentioned moving body (20) is formed to have a smaller size than the square-shaped opening (34) formed by the first rail (31) and the second rail (32) of the above-mentioned loading module (30) so as to be able to be moved in the up-and-down direction.

In addition, it may be configured to include an elevator device (50) that moves up and down at the front, rear, or side of the loading module (30).

The above-mentioned elevator device (50) may be configured in multiple units if necessary, and the above-mentioned elevator device (50) serves to transport the above-mentioned moving body (20) in the up-and-down direction.

Accordingly, the above-mentioned moving body (20) moves on the same floor by the first driving wheel (21) and the second driving wheel (22), and moves in the up-and-down direction by the above-mentioned lifting device (50) to a specific cell location.

Of course, the above-mentioned elevator device (50) is also configured so that its operation is controlled by the above-mentioned control unit (60).

In addition, the loading module (30) includes a detection sensor (35) installed on the rail of each opening (34) to detect whether a moving body (20) is loaded, and the signal of the detection sensor (35) is output to the control unit (60), and the control unit (60) recognizes an empty space based on the signal of the detection sensor (35).

In addition, a DC power source converted from an external power source to a DC power source is connected to the first rail (31) or the second rail (32), and when a moving body (20) is installed in each opening (34), the charging pack (70) mounted on the top of the moving body (20) is charged.

Meanwhile, the loading module (30) is formed as a three-dimensional frame structure, and a moving body (20) is placed in an opening (34) formed inside each, so that a large number of moving bodies (20) can be stored.

That is, the maximum number of cells calculated above can be stored, but for the movement of the moving body (20), the lower front, the upper and lower directions on the right, the entire front, and the entire central cell can be placed as empty areas.

In particular, in the case of the lower part and the right upper and lower directions, if an empty area is set for the discharge of the moving body (20), the moving body (20) equipped with the used charging pack (70) can be operated in a manner in which the moving body (20) equipped with the charging pack (70) to be discharged is brought in from the left, and the moving body (20) equipped with the discharged charging pack (70) is discharged from the right.

In particular, it is preferable that the control unit (60) be operated in a manner that sets the arrangement order of the moving bodies (20) in advance, arranges the moving bodies (20) based on the order, and discharges the moving bodies (20) arranged first.

In particular, the lower region includes an export section (41) and an import section (42) from which the first rail (31) and the second rail (32) extend, and in order to allow movement of the entire deployed moving body (20), the moving body (20) may be operated in a manner that no moving body (20) is deployed in some open section (34) of the lower region.

The above control unit (60) may include a configuration in the discharge unit (41) and the import unit (42) that can recognize the ID of the corresponding mobile unit (20) and the ID of the charging pack (70) in order to recognize that the charging pack (70) is discharged according to the movement of the mobile unit (20) and that the discharge unit (41) and the import unit (42) are re-coupled to the mobile unit (20).

For example, a mobile device (20) and a charging pack (70) may be provided with a reader that attaches a reader and recognizes information from the reader.

When including the above configuration, the control unit (70) can manage information on all moving objects (20) and charging packs (70) loaded on the loading module (30) using information from the detection sensor (35), and can manage the history of loading and unloading, etc.

Additionally, the control unit (60) may include a cost processing function that processes costs when a user takes out a charging pack (70).

Meanwhile, the station (10) may include a charging port (110) at the top for charging the drone, as shown in FIG. 10.

The above charging port (110) is configured to include a structure for mounting the drone and a connection for supplying electricity to the drone, and may include a wireless charging structure that can charge wirelessly if necessary.

Of course, the charging port (110) is controlled by the control unit (60), and the control unit (60) may be configured to perform wireless communication with a drone approaching for charging, including a wireless communication module, if necessary.

In addition, the charging ports (110) may be arranged in multiple numbers on the top of the station (10), and in this case, it is preferable to configure them to be installed in a position where they do not interfere with each other.

If necessary, the charging port (110) can be used for UAM (Urban Air Mobility) charging.

At this time, the charging port (110) is configured to include structures for UAM charging, and may be increased in size compared to general drone charging, and structures that function as stairs may be additionally installed on the side of the station (10), and the structure of the station (10) must also be implemented with a strength that can support UAM, and when a plurality of charging ports (110) are installed, they must be installed within a range that does not cause interference with UAM, but it is usually preferable to install a single one.

If necessary, the charging port (110) can also be used to charge a mobility device that requires battery charging.

In addition, the station (10) including the charging port (110) can also be operated in a manner in which the charging port (110) is provided by moving to a required location using a vehicle, and can also be operated in a manner in which the battery pack (70) is provided for charging devices other than electric vehicles (drones, UAMs, etc.).

Meanwhile, if the charging port (110) is used for charging a delivery drone among drones, the station (10) may include a warehouse system (120) installed inside.

The above station (10) may be configured to include an inlet (121) at the top for inserting parcels, as shown in FIG. 11, and an outlet (122) at the side for discharging stored parcels.

Here, the inlet (121) and the outlet (122) include doors that perform an opening operation, and the outlet (122) can be installed on a side other than the side shown, and a plurality of outlets can be installed if necessary.

Of course, the above warehouse system (120) is implemented as a general automatic warehouse system that can automatically store and discharge items, and can be configured to be controlled by the control unit (60), and is preferably installed in a location separate from the loading module (30).

Accordingly, the station (10) acts as a reception center for receiving parcels, and when a user requesting a parcel selects the station (10) information, a parcel delivery drone lands at the station (10) and delivers the parcel, and the user can receive the parcel delivered at the station (10).

At this time, the user can receive or accept items to be delivered or delivered by using a kiosk, etc. installed at the station (10).

The above method has the advantage of overcoming the disadvantage of loss that occurs when delivering to the entrance of a conventional house.

Meanwhile, when the above station (10) is used as an unloading point for a delivery drone, it can be implemented as a two-story structure as shown in Fig. 12.

At this time, the first floor can be used as an electric vehicle charging station (10), and the second floor can be used only as a station for delivery drones (10).

The interior of the station (10) on the second floor is implemented only with a warehouse system (120), and stairs, etc. for user guidance may be added on the side of the outlet (122) for receiving parcels.

If necessary, the above stations (10) can be arranged in multiple numbers with their sides in contact with each other as shown in Fig. 13, and when arranged as above, there is an advantage in that they can be used as electric vehicle charging and UAM landing stations.

Additionally, as illustrated in Fig. 14, it can also be implemented in a form in which a single-layer and a double-layer configuration are combined.

Although the present invention has been illustrated and described above with respect to specific preferred embodiments, the present invention is not limited to these embodiments, and includes various forms of embodiments that can be implemented by a person having ordinary skill in the art to which the present invention pertains without departing from the technical idea of the present invention claimed in the claims.
