The present invention relates to an electric vehicle charging system installed in a highway rest area. The electric vehicle charging system includes a mobile lift-based charging means for charging a parked electric vehicle in a predetermined parking space, , And an electric vehicle charging system using solar light.

Specifically, the upper part 1 includes a loop 10 provided with a filling panel and a supporting base 11 for supporting the loop 10 on the ground; A lower portion 3 comprising a plurality of parking spaces; A central part (2) located between the upper part (1) and the lower part (3) and having a charging means (20) moving along the rail; A sensing unit 4 formed for each parking space and capturing or sensing an electric vehicle to acquire vehicle type information and driver type information; And a control box (5) formed in each of a single parking space or a plurality of parking spaces for performing settlement, charging electric power to the electric vehicle, and controlling the charging means (20) (20) is moved forward or backward along the rail, or is moved upward or downward, thereby reducing standby time required to charge electric power of an electric vehicle.

An electric vehicle is an electric power source that uses electricity to drive electricity. This electric vehicle has an advantage of not discharging exhaust gas at all. Recently, it has been actively developed in various fields under the name of Smart Car.

In the early stage of development, the diffusion was not active due to safety review and vehicle performance problems. However, electric vehicles are often seen on the road in the recent years, and it is expected that the penetration rate will gradually increase and the frequency of use will increase.

On the other hand, as a major reason for consumers to avoid the use of electric vehicles, the infrastructure for charging electric vehicles is not properly constructed. Even if you search by map (Naver Map: Electric Vehicle Charging Station) Is often difficult to see.

On the other hand, the charging stations for electric vehicles are not installed at all resting places, but you can see electric charging stations in large rest areas (such as some West Coast Expressway or Gyeongbu Expressway).

The related technology is as follows.

Japanese Patent Application Laid-Open No. 10-2011-0074807 discloses an electric vehicle charging apparatus having a starting preventing system during charging.

However, the above-described technique has a filling means on the ground in a form similar to that of a conventional lubricator, so that in the art of handling power, it can be very dangerous due to a synthetic or short circuit.

Also, although it is not mentioned in the above description, it is general that it is necessary to move to a charging station for charging, and it is troublesome that a driver has to move for charging.

As another technology, a parking and charging service provision system for electric vehicles is disclosed in Japanese Patent Application Laid-Open No. 10-2015-0033789.

The above-described technology is applied to an RFID tag which is issued to an electric vehicle entering a parking lot and in which parking information and charging information are mapped and stored, a charging device for charging the electric vehicle and storing charging information in the RFID tag, Based on the parking information and the charging information stored in the RFID tag through the charging device and the settlement device, and a charging device that charges and adjusts the charging and charging based on the parking information and the charging information, And a parking and charge management server that carries out parking and charge management for an electric vehicle in which parking and charging is performed in the parking lot ". The present invention relates to a parking and charging service provision system for an electric vehicle, Although it is exemplified that charging is possible only by parking,

Referring to Fig. 2 of the accompanying drawings, there is still a problem in that the risk of short-circuiting and short-circuiting can not be solved.

Japanese Patent Application Laid-Open No. 10-2011-0074807 (July 4, 2011) Published Japanese Patent Application No. 10-2015-0033789 (Feb.

An object of the present invention is to provide an electric vehicle charging system installed in a highway rest area, which is provided with a mobile lift-based charging means for charging an electric vehicle parked in a predetermined parking space, And an electric vehicle charging system using solar light.

An electric vehicle charging system using solar light according to the present invention for achieving the above object comprises an upper portion (1) including a roof (10) provided with a charging panel and a support (11) for supporting the roof (10) on the ground; A lower portion 3 comprising a plurality of parking spaces; A central part (2) located between the upper part (1) and the lower part (3) and having a charging means (20) moving along the rail; A sensing unit 4 formed for each parking space and capturing or sensing an electric vehicle to acquire vehicle type information and driver type information; And a control box (5) formed in each of a single parking space or a plurality of parking spaces for performing settlement, charging electric power to the electric vehicle, and controlling the charging means (20) (20) is moved forward or backward along the rail, or is moved upward or downward, thereby reducing the waiting time required to charge electric power of the electric vehicle.

The electric vehicle charging system using solar light according to the present invention is installed every resting place that is operated at an interval of 50 to 100 km of a highway, so that stable electric power supply and charging can be performed. In addition, There is an advantage that the power can be charged only by the operation, but the problem that the standby time is increased due to use of another driver can be solved.

Further, there is an advantage that the surplus power can be reversely transmitted, and the charging device can be arranged at the upper part on the basis of the driver or the electric vehicle, so that it is possible to escape from the danger of short circuit or synthesis.

In addition, even when the charging is stopped abnormally, the power supply can be cut off promptly, so that there is an advantage that the safety of the user (driver of the electric vehicle) can be improved.

The terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary meanings and the inventor can properly define the concept of the term to describe its invention in the best possible way And should be construed in accordance with the principles and meanings and concepts consistent with the technical idea of the present invention.

Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and are not intended to represent all of the technical ideas of the present invention. Therefore, various equivalents And variations are possible.

Before describing the present invention with reference to the accompanying drawings, it should be noted that the present invention is not described or specifically described with respect to a known configuration that can be easily added by a person skilled in the art, Let the sound be revealed.

The present invention relates to an electric vehicle charging system installed in a highway rest area. The electric vehicle charging system includes a mobile lift-based charging means for charging a parked electric vehicle in a predetermined parking space, , And an electric vehicle charging system using solar light.

The present invention will now be described with reference to the accompanying drawings.

First, referring to FIG. 1, an electric vehicle charging system using solar light according to the present invention mainly includes an upper portion 1, a middle portion 2 and a lower portion 3 in a highway rest area.

1 schematically shows a configuration of an electric vehicle charging system using solar light according to the present invention.

The upper part 1 comprises a loop 10 provided with a filling panel and a support 10 for supporting from the loop 10 provided with the filling channel to the ground so that the loop 10 equipped with the filling panel can be supported on the ground 11).

In this case, it is sufficient that the charging panel is constituted by a means capable of charging sunlight as described in the title of the present invention, and the configuration for charging sunlight is well known in the art, so a detailed description thereof will be omitted.

Of course, it is preferable that the electric vehicle charging system using solar light according to the present invention does not use only solar light for power consumption, but is mixed with an ordinary power source or other power source (all power sources predictable by an ordinary technician) . This is because, as electric vehicles become more widespread and the number of users using the present invention increases, or it may be difficult to cover the power consumption only by the sunlight depending on the weather.

At this time, it is a matter of course that the charging panel may use wind power, earth power, hydroelectric power (for example, Geumgang rest stop), etc. in addition to the sunlight described above according to design conditions.

The lower part 3 is configured to be in contact with the ground, and can be constituted by a parking space.

The central portion 2 is located between the upper portion 1 and the lower portion 3 and is specifically spaced apart from the lower portion 3 by a predetermined distance And is provided close to the lower surface of the loop 10 provided.

At this time, it is sufficient that the central portion 2 is separated from the upper portion 1 only to the extent that the charging means 20, which will be described later, can move.

The charging means 20 moves along the rails 21 and 23, and a plurality of charging means 20 can be formed in the central portion 2 as shown in Fig.

1, at least one of the plurality of charging means 20 is in a state in which the second guide 24, the motor 25, the rotary shaft 26 and the charging cable 27 are not provided, Only the first guide 22 and the second rail 23 may be present on the first rail 21. The second guide 24, the motor 25, the rotary shaft 26, and the second guide 24 provided in any one of the plurality of charging means 20 provided on the one of the first rails 21, And the charging cable 27 to a second rail on which the second guide 24 on the other first rail, the motor 25, the rotary shaft 26 and the charging cable 27 are not provided .

The reason why such a configuration is necessary is that the charging means 20 can be moved upward or downward in addition to advancing or retracting in the rail direction. This will be described with reference to FIG. 1, Assuming that the charging means indicated by the reference numerals and the charging means indicated by the reference numeral 20a are being charged at the respective positions shown in Fig. 1, when the electric car located at the top 6 o'clock of the parking space of the lower portion 3 tries to charge , The driver of the electric vehicle must wait for the charging of the charging means indicated by the reference numeral 20a to be completed. In such a case, it is very inconvenient for the driver of the electric vehicle waiting. Further, in FIG. 1, three charging means are exemplified. However, if the number of parking spaces is three or more, or the number of charging means is four or more, the waiting time becomes long.

Therefore, in the present invention, the configuration such as the second guide 24 of the charging means 20 is moved to the first guide 22 and the second rail 23 shown in FIG. 1 to enable charging. A specific configuration will be described later with reference to Fig.

Hereinafter, the charging means will be described in detail with reference to FIG.

Fig. 2 shows the configuration of a charging means in an electric vehicle charging system using solar light according to the present invention.

2 includes a first rail 21, a first guide 22, a second rail 23, a second guide 24, a motor 25, a rotary shaft 26, And includes a charging cable 27 mainly.

The first rail 21 is a rail formed in the longitudinal direction of the central portion 2 and is made of a material that can be energized so that the first rail 21 is provided with positive and negative terminals, Current flows. That is, as will be described later, this is also true of the second rail 23, and the electric power charged through the loop 10 equipped with the filling panel is stored in the electric power storing portion of the control box 5, 21). The first rail 21 is formed by a pair of two rails, and a plurality of the first rails 21 constituted by a pair may be provided parallel to each other.

The first guide 22 moves forward or backward along the first rail 21. The first guide 22 is also made of a material that can be energized, which is also true of the second guide 24.

As shown in FIG. 2, when the first guide 22 moves along the first rail 21, the first guide 22 moves along a predetermined groove provided in the first rail 21, Or the first guide 22 may be moved along the first rail 21 via the servomotor so as not to affect the current flowing depending on the electrification material of each configuration It can be configured as long as it is a configuration that can be moved.

In addition, the first guides 22 are formed by two in the longitudinal direction of the first rail 21, and are configured to face each other with respect to a pair of first rails 21 as shown in FIG. 2, . However, the present invention is not limited to this, and it is needless to say that it may be constituted of six or three or more pairs.

The second rail 23 is formed on the upper portion of the first guide 22 so as to be connected from the first guide 22 to the first guide 22 facing the other first guide 22.

The second guide 24 can be moved upward or downward along the second rail 23, wherein the second guide 24 has four first guides 24, as shown in FIG. 2 of the accompanying drawings, If two second rails 23 are formed on the base 22, one of the second rails 23 is provided to face each other.

The motor 25 is formed on the upper side of the second guide 24. The rotary shaft 26 is connected to the motor 25 and is configured to rotate along the rotation direction of the motor 25, (26) is positioned in an empty space between the opposed second guides (24).

A charging cable 27 is wound around the rotating shaft 26 so as to surround it. Therefore, the rotation of the rotary shaft 26 causes the charging cable 27 to be wound or unwound. At this time, a jack (a jack or a port) for charging a conventional electric vehicle may be formed at one end of the charging cable 27.

Referring to FIG. 3, the electric vehicle charging system according to the present invention may further include a sensing unit 4 and a control box 5.

FIG. 3 shows an example of charging an electric vehicle in an electric vehicle charging system using solar light according to the present invention.

The sensing unit 4 is provided for each parking space formed in the lower portion 3 and may be installed from the ground or on the wall if there is a wall. The function of the sensing unit 4 is to (a) capture the electric car parked in the parking space Or (b) a function of photographing or sensing the driver of the electric vehicle.

The control box 5 is provided for each of the parking spaces as in the case of the sensing unit 4, or (b) is provided for each predetermined number so as to manage the plurality of parking spaces, or (c) One space may be provided.

In the case of (b) and (c), it is needless to say that the identification information is stored in the database so that a plurality of parking spaces can be identified. At this time, the identification information can be inputted by the designer in the initial designing.

Before describing this control box 5 in detail, an example in which the charging means 20 moves upward or downward will be described with reference to FIG.

4 shows an example in which the charging means moves upward or downward in an electric vehicle charging system using solar light according to the present invention.

As described above, the charging means 20 according to the present invention can be moved upward or downward based on the control of the control box 5, 2 < / RTI > sensors.

The first sensor is constituted by a sensor capable of sensing a load (weight) of the second guide 24. [ The second sensor is configured on both of the (a) forward and backward directions of the second guide 24 and (b) both the upward and downward directions, and functions as an object detecting sensor.

At this time, it is configured on both sides of the forward and backward directions of (a), so that it is determined whether other charging means 20 exists to prevent collision when advancing or retracting.

Further, it is configured on both of the upward and downward directions of (b), thereby sensing the second guide located in the other column.

Referring again to FIG. 4, as described above, the charging means 20 confirms whether there is a second rail 23 located in another column via the second sensor under the control of the control box 5, (The motor 25, the rotary shaft 26, etc.) of the second guide 24 existing on the upper side of the second rail 23 in accordance with the load of the second rail 23, 2, the following configuration of the second guide 24 is moved to the second rail 23 of another row, as shown in FIG. 4 (b).

However, when the second guide 24 is moved, the second sensor should be configured to sense that the second rail of the other row is located at a position completely coincident with the second rail having the second sensor.

And if the two second rails do not exist at the completely matched position, they must be controlled to be in a completely matching position through the control of the control box (5).

This is because the second guide must be able to move from one second rail to the second rail of the other row.

In order to achieve this, (a) when the configuration of the second sensor is constituted by a proximity sensor which receives the reflected light and emits the light again, the side surface of the second rail (B) when the second rail of the other row and the second rail of the other row are located at exactly the same position, the light outputted from one second rail is compared with the shape detected by the second sensor To be received in the light receiving arrangement provided on the second rail of the other row, so that the two second rails are in the same position, and if not, can be controlled under the control of the control box (5).

As described above, as described above, as described above, as the charging means 20 is allowed to move upward or downward, the charging means 20 and the charging means 20a 1, even when the electric car located at the 6 o'clock position of the parking space of the lower portion 3 tries to charge, the charging means (not shown in Fig. 1) 20 can be used to quickly perform charging.

Hereinafter, the control box 5 will be described with reference to FIG. 5 of the accompanying drawings, and detailed functions of the present invention will be described in detail.

5 is a block diagram of a control box of an electric vehicle charging system using solar light according to the present invention.

The control box 5 includes an operation interface and a payment unit so that the electric vehicle driver can pay for the electric charge and perform charging.

In other words, the settlement unit makes all the payment (including the gift certificate) including the card or the cash possible as the means for the payment of the cost, and provides all the functions such as the cash change and the refund for the failure to charge the predetermined amount of power.

Further, the operation interface functions to provide all interfaces (I / F) for performing functions of the present invention such as settlement, charge amount setting, start of charge, and end of charge.

Hereinafter, the configuration of the control box 5 will be described with reference to an operation relationship with reference to Figs. 1 to 5, which are attached heretofore.

The communication unit receives the vehicle type information and the driver type information photographed or sensed from the sensing unit 4. [ At this time, the reason why the sensing unit 4 is described as photographing or sensing is that the sensing unit 4 is configured by a camera to photograph an electric vehicle and a driver, and is configured by a microwave or an infrared sensor to detect the shape of the electric vehicle and the driver This is because we can do it.

In addition, the communication unit also communicates with the above-described first sensor and second sensor to receive a sensing value.

The database stores vehicle information and driver information.

In this case, the vehicle information means morphological information about the electric vehicle, and is information for grasping the front parking or the rear parking of the electric vehicle.

The driver information stores the height of a person's height as morphological information. That is, a person has various keys ranging from 150 cm to a maximum of 2 m (or more). By storing driver information for such a key in advance and comparing the information with the driver type information described later, the driver's key obtained from the driver type information becomes several cm .

Such vehicle information and driver information become morphological information as pixel information when photographed by a camera or the like, and when light emitted by a sensor is reflected by a driver or a vehicle, And may acquire information about the subject.

In addition, it may further include power information such as an amount of power corresponding to a settlement amount for power consumption, or may include reverse power transmission of surplus power that is received but not used through power reverse transmission.

Further, motor control information for controlling the motor based on the driver information and the vehicle information may be further included.

The comparison matching unit compares the vehicle type information or the driver type information by the sensing unit 4 with the vehicle information or the driver information of the database.

According to the comparative matching unit, the vehicle type of the parked electric vehicle and the parking mode (front or rear) of the electric vehicle can be grasped and the driver's key of the electric vehicle can be grasped.

The movement control unit controls the movement of the first guide 22 and the second guide 24. In particular, when the movement of the second guide 24 is controlled, the first sensor 22 and the second guide 24, (Communication) with the sensor.

When the movement of the second guide 24 is controlled as described above, the controller controls the second guide 24 to move in accordance with the front parking or the rear parking of the electric vehicle determined through the comparison and matching unit.

Accordingly, in the case of the front parking, the second guide may be moved to correspond to the position of the filling port as shown in FIG. 3. At this time, the movement control of the second guide may be performed according to the vehicle type of the electric vehicle determined based on the vehicle information and the vehicle type information It can also be different. This is because the position of the filling port may be left or right depending on the type of vehicle, and the detailed position may be slightly different.

Thereafter, the motor can be controlled so that the charging cable 27 is wound and unwound according to the driver's key, which will be described later through the motor control section.

The power storage unit functions to store electric power generated by the loop 10 equipped with the charging panel. In addition, the power reverse transmission section performs a function of transmitting the supplied electric power to the source (KEPCO, etc.) in reverse, as follows.

(a) when both commercial power and solar power are used simultaneously, reverse transmission of the supplied commercial power or

(b) reverse transmission of the power obtained with solar power

The motor control unit functions to control the motor 25. At this time, the control of the motor 25 controls the motor to operate according to the detected key (cm) of the driver by comparing and matching the driver type information and the driver information so that the charging cable 27 is loosened to fit the key of the driver Function.

The motor initialization unit performs a function of initializing the motor 25 controlled by the motor control unit and initializing the charging cable 27 to be wound around the rotary shaft 26 when the charging of the electric vehicle is completed.

According to other design conditions, the present invention may be configured such that the supplied power is automatically shut off when the charging is stopped by an abnormal factor during power charging.

For this, the control box 5 may further include an emergency stop detection unit and a power supply cutoff unit, and the emergency stop detection unit may be provided on one side of the control box 5 or the charge cable 27 as a button So that it is detected that the driver presses it, or a circuit problem is detected.

The power supply cut-off unit functions to cut off the power supplied to the charging means 20 when there is the above detection.

1 to 5 are merely the main points of the present invention. As various designs can be made within the technical scope of the present invention, the present invention is limited to the configurations of Figs. 1 to 5 It is self-evident.
