Description

Electric vehicle charging system for underground parking lot of apartment complex {Electric vehicle charging system for parking lot}

The present invention relates to an electric vehicle charging facility system, and more specifically, an electric vehicle for an underground parking lot in an apartment complex that can improve the efficiency of parking surface use for internal combustion engine-type vehicles and electric charging vehicles and can be installed at low cost. It is about the charging facility system.

Recently, the need for carbon neutrality is increasing in response to climate change caused by global warming. Carbon neutrality refers to the concept of reducing the use of fuels that produce carbon emissions, such as oil and coal, as much as possible and reducing carbon emissions to zero when necessary. To this end, the need and demand for electric vehicles as an alternative to internal combustion engine vehicles is increasing.

Electric vehicles use electricity as a power source, so charging large-capacity batteries for long-distance and long-term driving is essential, and charging stations for electric vehicles are increasing nationwide to increase the penetration rate of electric vehicles.

Meanwhile, underground parking lots are required to be installed in common houses such as apartments, and with the recent increase in the spread of electric vehicles, it is mandatory to secure a certain number of parking spaces exclusively for electric vehicles in the parking lots of apartment complexes. For example, the Ministry of Trade, Industry and Energy, through the revised enforcement ordinance in January 2022 as the 'Act on the Promotion of Development and Distribution of Environmentally Friendly Vehicles', requires that even in the case of already-built apartment houses, chargers are installed so that the entire parking area where electric vehicles can be charged is installed. It stipulates that at least 2% of the parking area must be provided, and that newly built apartment complexes must have at least 5% of the charging station parking area.

In addition, as per related laws, if a general vehicle other than an electric vehicle parks on the charging station parking lot, or parks in a position that interferes with the parking of an electric vehicle, or places objects, etc. in a location that interferes with the parking of an electric vehicle, However, if you park for an excessively long time, you will be fined.

However, despite these regulations, compared to the increasing number of electric vehicles in common residences, the rate of secured parking spaces at charging stations is extremely low, making it difficult for electric vehicle drivers to find empty charger parking spaces. ,In addition, there are many cases where ordinary vehicles are parked at ,charging station parking areas, or electric vehicles are parked for ,excessively long periods of time even after charging is ,complete, thereby interfering with the charging of others.

If the relevant public officials do not crack down on these acts or citizens do not report them, it is not only difficult to crack down on illegal activities, but it is also close to impossible to crack down on all charging stations every hour with the limited manpower of public officials, and citizens also face uncomfortable situations between neighbors. There are many cases where people do not report it because they are concerned about what will happen.

To solve this problem, it is desirable to install chargers in a large number of parking spaces. For example, Korean Patent No. 10-2356649 installs a raceway with a mounting part on the ceiling of a parking lot, and uses the mounting part of the raceway to connect the charging connector connected to the end of the cable to the electric vehicle charging connector to enable charging. We are proposing an electric vehicle charging system for parking lots.

However, the electric vehicle charging system in the prior literature has the disadvantage of being difficult to install because the power supply equipment must be installed on the ceiling of an underground parking lot, and is very cumbersome to use because the charging connector is located high up so as not to impede the movement of the vehicle.

Korean registered patent 10-2356649 (electric vehicle charging system for parking lots) Korean Patent Publication No. 10-2020-0084208 (Parking lot wall mobile electric vehicle automatic charging system)

The technical problems achieved by the present invention and its implementation will become clear by the preferred embodiments described below. Hereinafter, preferred embodiments of the present invention will be examined in detail with reference to the attached drawings.

It should be understood that the differences in this embodiment, described later, are not mutually exclusive. That is, without departing from the spirit and scope of the present invention, the specific shape, structure, and characteristics described may be implemented in other embodiments with respect to one embodiment, and the positions of individual components within each disclosed embodiment. Alternatively, it should be understood that the arrangement may be changed, and similar reference numbers in the drawings refer to the same or similar functions across various aspects, and the length, area, thickness, etc. may be exaggerated for convenience. In the description of this embodiment, expressions such as front, back, top, bottom, first, second, etc. indicate relative positions, directions, and orders, and their technical meaning is not limited by dictionary meaning.

Figure 1 is a conceptual diagram showing the structure of a parking lot equipped with electric vehicle charging facilities according to an embodiment of this project. The electric vehicle charging facility of this embodiment can be installed in an underground parking lot of an apartment complex, but is not limited to this, and can also be installed in indoor or outdoor parking lots such as large buildings or public places equipped with pillars or support structures at predetermined intervals. Below, we look at the electric vehicle charging facility system for this project using an underground parking lot in an apartment complex as an example.

Referring to the drawing, generally, in the underground parking lot of an apartment complex, pillars (S) are installed at predetermined intervals to ensure safety, and three parking surfaces (P) are usually provided between neighboring pillars (S). The parking surface (P) is formed in a row along the vehicle access road and is formed in a symmetrical structure facing each other with the access road as the center. In addition, a charging station (C) is installed and operated in front of the pillar (S).

Regular vehicles (MV) and electric vehicles (EV) can park in each parking surface (P). In particular, electric vehicles that need charging must be parked in the parking surface (P) on the left or right side of the pillar (S). During parking time, you can charge using the charging station (C) installed in front of the pillar (S). It is desirable that the charging station (C) be configured with a charger with a dual charging structure so that a pair of electric vehicles (EV) parked on the parking surface (P) on both sides of the pillar (S) can be charged simultaneously. In addition, the charging station (C) is preferably configured as a slow charger that can be operated at a relatively low cost.

In this way, since the charger installed on each pillar (S) must be supplied with grid power, power supply equipment connected to the power supply server of the apartment complex must be constructed. Below, we will look in detail at the electric vehicle charging facility system installed in the underground parking lot of an apartment complex to receive power from a power supply server.

FIG. 2 is a conceptual diagram showing an electric vehicle charging facility according to an embodiment of this project, FIG. 3 is an exploded view showing the distribution board, which is the main part of FIG. 2, and FIG. 4 is a front view showing the distribution board, which is the main part of FIG. 2.

First, referring to FIG. 2, the electric vehicle charging facility system of this embodiment includes a unit distribution board 100 installed on the front upper part of each pillar, a charger 200 installed on the front lower part of each pillar S, and a plurality of Connecting the metal wire 300 that crosses the pillar (S), the distribution board (100) of the neighboring pillar (S) while being supported by the metal wire (300), and connecting the distribution board (100) and the charger (200). Includes a power transmission cable 400.

Looking specifically, the distribution board 100 is configured to receive power from a power supply server (not shown) and supply charging power of a certain amount to the charger 200 installed on a pole. The distribution board 100 is connected to the power supply server through a power transmission cable 400 for transmitting power, and each distribution board 100 is connected to the power supply server in a series or parallel structure through the power transmission cable 400. connected to Since each distribution board 100 should not interfere with the movement of the electric vehicle, it is desirable to install it at the top of the pillar S, that is, as close to the ceiling as possible. The distribution board 100 can be installed on the front or back of the pillar, and in this embodiment, it is installed on the front.

The charger 200 is a dispenser that supplies charging power according to the user's request and operation, and charges the electric vehicle by receiving a predetermined amount of power distributed from the distribution board 100 through the power transmission cable 400. The charger 200 may be installed on the front or back of the pillar S in the same direction as the distribution board 100, and in this embodiment, it is installed on the front. In addition, the charger 200 is preferably installed at the bottom of the pillar, that is, at a somewhat low position where the user can conveniently use the charger 200.

Additionally, considering installation and operating costs, the charger 200 is preferably configured as a slow charger. The charger 200 may be provided with a pair of inlets to enable simultaneous charging of a pair of electric vehicles parked on the left and right sides. The charger 200 may be equipped with a display module or touch panel module for user operation as well as a charging module for charging, and may communicate with a user authentication, payment, and charging station management system (CSMS) for charging. To enable this, a user authentication module, payment module, and communication module may be further provided.

In this way, the distribution board 100 and the charger 200 form a pair and are installed at predetermined intervals at the top and bottom in front of the pillar, and the power distributed from the distribution board 100 through the power transmission cable 400 is transmitted to the charger ( 200).

The metal wire 300 supports the power transmission cable 400 connecting the power transmission server and each distributor 100 and is made of a steel wire made of metal. Since the metal wire 300 is relatively light compared to a metal pipe, it has the advantage of convenient installation and low cost.

In addition, the metal wire 300 is installed on the path from the power supply server to each distribution board 100, and is fixed to a pillar or ceiling through a fixing part 310 such as an anchor member, and each fixing part 310 It is installed to have strong tension to stably support the power transmission cable 400. The metal wire 300 can be installed on the ceiling, and considering convenience of installation work, it is preferable to install it on the pillar S located above the distribution board 100.

The power transmission cable 400 transmits the power supplied from the power supply server to each distribution board 100, and simultaneously transmits the power distributed from the distribution board 100 to the charger 200 of the distribution board 100.

In this embodiment, the power transmission cable 400 connecting each distribution board 100 is composed of a flexible aluminum clad flex cable, that is, an ACF cable. ACF cable is a cable with high-strength aluminum interlock applied to the outside of the conductive power line. It has the advantage of being flexible, making it easy to handle and work, and enabling quick and effective wiring installation. The power transmission cable 400 between the distribution board 100 and the charger 200 may also be composed of an ACF cable, but since it transmits power over a short distance, it may also be composed of a regular power cable.

Here, the power line may consist of multiple power lines depending on the power transmission method. For example, in a single-phase, two-wire power transmission structure, it consists of three power lines, and in a three-phase, three-wire power transmission structure, it consists of five power lines. It can be. The ACF cable has a structure that surrounds a 3- or 5-strand power line with flexible aluminum.

In general, the power transmission means that implements an electric vehicle charging system is configured to insert a power line inside a metal tube and protect the power line by the metal tube. This means of power transmission has the advantage of safely protecting power lines by using metal pipes, but has the disadvantage of being difficult to handle due to its weight, making installation work very difficult, and requiring a high level of installation cost. In addition, since power transmission means using metal pipes must be constructed along the floor of a parking lot, there is a disadvantage in that the installation path is limited to avoid interference with driving vehicles.

The power transmission cable 400 of this embodiment is installed to be fixed to the metal wire 300 by binding members 410 that are installed along the metal wire 300 and fastened at predetermined intervals. ACF cables have the advantage of being light and flexible, making construction convenient, but they are disadvantageous in fixation and have somewhat insufficient protection from external structures. However, as in the present embodiment, it can be stably fixed by being fixed to the metal wire 300, and is installed at a high position so that it does not interfere with external structures or moving objects, enabling efficient protection from them. In addition, the power transmission means that combines metal wire and ACF cable has an installation path designed close to the ceiling, that is, along the top of a pillar, so it does not interfere with vehicle movement and has the advantage of being free in the installation path.

Therefore, the electric vehicle charging facility system of this embodiment has the effect of being able to be conveniently constructed without limitation not only in the parking lot of a newly built common house, but also in the parking lot of an already built common house.

Meanwhile, referring to Figures 3 and 4, the distribution board 100 of this embodiment is fastened to a terminal connection module 110, a main body 120 in which the terminal connection module is accommodated, and covering the main body 120 to connect the terminal. It includes a cover 130 that protects the module 110.

The terminal connection module 110 is a module that connects the power terminal of the power transmission cable 400. A plurality of busbars 112 are coupled to a metal plate 111 of an insulating material, and each busbar 112 has a plurality of busbars 112. The connection terminal 113 may be configured to be combined. A plurality of busbars 112 may be provided depending on the number of power lines of the power transmission cable 400. For example, for a cable with a single-phase two-wire power transmission structure, it may be composed of three bars, and each busbar 112 ), the first power terminal (L1), the second power terminal (L2), and the ground terminal (G) of the power transmission cable 400 are connected to each other. In addition, the terminals of the power transmission cable 400 connected to the power supply server on the left and right sides of the distribution panel and the terminals of the power transmission cable 400 connected to the charger 200 at the bottom are fastened to each busbar 112, respectively. do.

The main body 120 is installed to be fixed to the pillar wall and accommodates the terminal connection module 110 therein. The main body 120 is open at the front and forms a box shape with a predetermined width, height, and depth.

Assembly holes 121 where the power transmission cable 400 is assembled are formed on the left, right, and lower side walls of the main body 120. The assembly holes 121 may be formed on the main body side walls in three directions, that is, on the left, right, and bottom. The assembly hole 121 is formed in a 'U' shape with a front opening, and is configured to allow the power transmission cable 400 to be assembled by inserting from the front to the back of the main body 120.

In general, when the assembly hole forms a closed circular shape ('O' shape), the worker must insert the end of the power transmission cable 400 while positioning it exactly at the center of the circular assembly hole, depending on the working conditions. In this difficult environment, it is difficult to accurately align the cable end with the center of the assembly hole.

However, as in the present embodiment, when the assembly hole 121 is formed in a 'U' shape with the front open, the cable end can be assembled by inserting it from the front to the back, so the assembly work can be easily performed. In addition, for this purpose, a cable gland 420 is configured to be coupled to the end of the power transmission cable 400, and the power transmission cable 400 can be assembled and fixed to the main body via the cable gland 420. The cable gland 420 exposes the power line through its interior, and a groove and protrusion structure is formed on the surface, so that it can be assembled and fixed to the side wall of the main body 120 by pressure fitting.

The cover 130 covers the front of the main body 120 and is fastened to the main body 120 to protect the internal terminal connection module 110 from the external environment. For this purpose, fastening means (not shown) are formed on the outer surface of the main body 120 and the inner surface of the cover 130. For example, fastening means of hook structures corresponding to each other may be provided.

Additionally, the cover 130 is open at the rear and forms a box shape with a predetermined width, height, and depth. In addition, the cover 130 is fastened to the main body 120 and has a sufficiently large height to accommodate the metal wire 300. An avoidance hole 131 through which the power transmission cable 400 and the metal wire 300 can be avoided is formed on the side wall of the cover 130. The avoidance hole 131 is preferably formed in a 'U' shape with an open rear end. The cover 130 configured as described above can be fastened to the main body 120 with its rear end in contact with the pillar without interfering with the power transmission cable 400 and the metal wire 300.

In addition, a status display unit 132 indicating the usable state of the charger 200 may be further formed on the front of the cover 130. The status display unit 132 includes a sensor unit that detects the operation of the charger 200 and a lamp unit that emits light in different colors depending on whether the charger 200 is driven. Accordingly, the status display unit 132 may illuminate in green when the charger 200 is in a usable state, and may illuminate in red when the charger 200 is in an unusable state. At this time, the sensor unit and the lamp unit may be provided on the metal plate 111 of the terminal connection module 110 and configured to display a usable state through the status display unit 132.

Figure 5 is a conceptual diagram showing the structure of a parking lot equipped with electric vehicle charging facilities according to another embodiment of this project.

Referring to the drawing, the electric vehicle charging facility of this embodiment is installed on the back of the pillar (S). If the width of the vehicle travel path is narrow, the charger 200 may interfere with the vehicle's driving or the user's walking, so the charging facility system may be installed on the back of the pillar. In this case, since the user cannot check whether the charger 200 installed on the back is in a driving state, that is, in a usable state, the status display unit 132 notifying the status of the charger is separately installed on the front of the pillar.

Therefore, the user (driver) can drive along the road, find a parking space with an available charger, park, and then use the charging facility system.

Although exemplary embodiments of the present invention have been shown and described as described above, various modifications and other embodiments will occur to those skilled in the art. These modifications and other embodiments are to be considered and included in the appended claims without departing from the true spirit and scope of the present invention.
