JP6649554B2 - A charging stand for electric vehicles that can be charged simultaneously - Google Patents

Description

The present invention relates to a charging station for electric vehicles (EV and PHV) powered by electricity.

Electric vehicles with low fuel consumption and environmental friendliness are expected to become widespread in the future, but the key to their promotion is to install infrastructure such as installing a number of charging stations throughout the city so that they can be charged anytime, anywhere. That is.

The biggest advantage of the charging cost corresponding to the fuel cost of electric vehicles is that it is inexpensive, a fraction of that of gasoline, etc., but there is a problem that the profit is small when the charging service is viewed as a business. Therefore, the charging equipment must be economical.

On the other hand, as an inexpensive charging stand that can be used by anyone, a type that includes only an outlet for connecting a charging cable and that allows an electric vehicle user to connect his or her own charging cable to an outlet for charging is suitable. However, the charging cable is provided with a control device called CCID for controlling charging, and although electrical safety is ensured, the charging cable itself is expensive, so there must be a mechanism to prevent theft during charging. Must.

JP 2011-182640 JP 2011-279181

In order to prevent theft or mischief of the charging cable, Patent Literature 1 discloses that after connecting the charging cable to an outlet, the main parts including the CCID device are stored in a storage portion provided in a charging stand, and a lockable door is used for charging when charging. A charging stand having a rectangular housing having a structure in which a charging cable cannot be disconnected from an outlet is shown.

However, when the size of the housing is reduced to make such a charging stand smaller, there is no space for a control device that controls power supply to the outlet, and there is no storage space for plugs and CCID devices. Since the size of the unit is reduced, connecting the charging cable and storing the cable including the CCID device becomes very difficult.

Further, Patent Document 2 discloses a storage unit for storing a charging cable for one circuit and a CCID device for controlling charging in order to charge two or more electric vehicles with such a charging stand. Although the charging stand is shown as a unit and is provided with a plurality of stacked units, since multiple circuits are provided in the same direction, when charging at the same time, when connecting the charging cable at the same time, work is required. There was a drawback of interference.

In addition, the charging cable for these charging stands and the door of the storage section that stores the CCID device are made of metal, so a plug was connected to the outlet, the CCID device and cable were stored, and the door of the storage section was closed. Also, there was a drawback that the connection status could not be checked.

Further, the device for preventing theft of the charging cable is only performed by locking the door of the storage section, and no further reliable auxiliary means is provided.

The present invention is aimed at a charging stand of a small rectangular housing in pursuit of economy, but as the housing becomes smaller, a storage portion for storing an outlet, a plug, a CCID device and a cable is inevitable. Therefore, the space for providing a control mechanism for controlling the lock mechanism of the door of the storage unit, the control wiring thereof, and the power wiring to the outlet is reduced.

Therefore, in the charging stand of the present invention, the control device is provided in the control box collectively for two circuits at a lower part or an upper part of a storage part such as a charging cable of the charging stand. It becomes difficult to secure a route through which power wiring to the control device and wiring of a control device such as a lock mechanism are passed. If a wiring route is forcibly formed in the storage unit, it takes a long time to perform the wiring work, and there is a disadvantage that the effect of cost reduction is lost and that it is difficult to inspect the wiring. The first problem to be solved by the present invention is to remedy this drawback.

Next, in order to be able to charge two electric vehicles at the same time with a charging stand having a rectangular casing, if the connection portions of two charging cables are arranged side by side on the same surface, the width of the charging stand becomes large. Would. If a wide charging station is installed between the two compartments in the parking lot, there is a high possibility that a car entering the compartment will hit the car, leading to trouble such as damage to the charging station or short-circuiting of the power line in some cases. There is fear. Solving this is a second problem.

Also, if the connection part of the two charging cables is provided on the same surface on a different level, the width of the charging stand will not be large, but if two vehicles try to connect the charging cable at the same time, the work will interfere with each other. The drawback is that it becomes difficult. This is the third problem to be solved.

In addition, it is common practice to provide a lock mechanism that locks electromagnetically during charging while the door of the storage unit that stores the CCID device, etc. Expensive charging cables may be stolen due to actions such as breaking doors. A fourth object of the present invention is to solve this.

Furthermore, in the conventional charging stand, since the door of the storage unit that stores the CCID device and the like after the charging cable is connected is made of metal, when the door is closed, the inside becomes invisible and the connection state of the charging cable is checked. I couldn't do that. This is another issue that we want to solve.

An object of the present invention is to manufacture a small and economical charging stand capable of charging two or more conventional electric vehicles as described above, and to solve the problems related to convenience in use.

In the charging stand with a substantially rectangular housing, the storage section that stores the charging connection parts such as the outlet, the connection plug, the charging cable, the CCID device for charging control, the electromagnetic lock device, etc. is housed in the housing with a square cross section. Two sets are built, and a door is provided in the storage unit, and a control unit that controls the power supply to the outlet and the electromagnetic lock device of the door is provided in the control box provided at the bottom or upper stage of the housing In addition, the wiring to the outlet and the electromagnetic lock device is connected to the connection terminal in the control box through the outside of the housing, thereby realizing a small and economical charging stand with reduced wiring work cost.

A charging stand that uses a rectangular and small housing that can charge two electric vehicles at the same time, and stores outlets, connection plugs, charging cables, charging connection parts consisting of a CCID device for charge control, an electromagnetic lock device, etc. The two sets of storage units are formed in a rectangular housing so that the doors of the storage units are opened stepwise and in opposite directions on two adjacent surfaces , so that the width of the charging stand is not increased and two sets of storage units are provided. Even when the electric vehicles connect the charging cable almost at the same time, the charging station has been realized so that the connection work does not interfere with each other.

In addition, a storage section that stores charging connection parts such as an outlet, a connection plug, a charging cable, a CCID device for charging control, an electromagnetic lock device, etc., and a door that closes the storage section in a square-shaped housing. In the provided charging stand, at least a part of the door is made transparent so that even if the door of the storage unit is closed after the connection of the charging cable, the inside condition can be checked from the outside.

Furthermore, as an additional means of preventing the charging cable from being stolen, a closed annular clasp is provided on the surface of the housing in the immediate vicinity of the place where the charging cable is pulled out of the storage section containing the CCID device, etc. The charging cable can be fixed to the charging stand using a lock brought at the place where the user pulls out the cable from the storage section.

According to the present invention, a manufacturer can provide an economical charging stand that can simultaneously charge two batteries while using a small square housing, and for a user, even if two charging cables are connected at the same time. Work is not interfered with each other, and even after the CCID device etc. is stored in the storage unit, the connection status of the charging cable and the operation status of the electromagnetic lock device can be checked, and theft of the charging cable can be ensured, so that it can be used with the manufacturer. There is a great effect that it is possible to provide a charging station that allows both users to enjoy the benefits.

At the time of charging, plugs 5 and 6 of charging cables 9 and 10 with CCID devices 7 and 8 for charging control are connected to the outlets. Thus, electric power can be supplied to an electric vehicle.

Although two charging stands can be charged at the same time, since the outlets are provided side by side on the front of the stand, the lateral width W of the stand increases. If a wide charging station is placed in the middle of the parking space where two parking spaces are arranged in a parking lot, there is a drawback that a problem of the vehicle hitting the vehicle body when entering the vehicle room is likely to occur.

Further, in the charging stand as shown in FIG. 1, there is a disadvantage that the CCID device and the outlet are exposed to the weather.

FIG. 2 shows a charging stand according to the present invention, which can charge two units at the same time. The stand body is constituted by a casing having a square cross section .

In the charging stand of the present invention, storage sections 23 and 24 of the charging connection device are provided on two adjacent surfaces of a square casing at different levels, and a control device for controlling power supply is a control box 25 arranged at the bottom. It is provided within. The charging stand stands upright on the base 22.

According to the present invention, doors 26 and 27 are provided in the storage section of the charging connection device, and each is opened in a different direction. In this way, the storage portions of the charging connection device are provided on two adjacent surfaces at different levels, and the respective doors are opened in opposite directions, so that even when charging two devices at the same time, the connection work of the charging cables can be performed mutually. There is an advantage that it can be performed independently without interference.

After the charging cable is connected to the outlet, the cable is pulled out from the lower part of the doors 26 and 27, and closed annular clasps 28 and 29 are attached to the lower part of the outlet. The clasp is an auxiliary device for preventing the charging cable from being stolen, as will be described later, and is used to fix the cable using a locking device brought by a charging user.

FIG. 3 shows a cross section of the storage section 23 of the charging connection device. Inside, there are an outlet 44, a door electromagnetic lock device 40, and a cradle 43 for a CCID device for charge control.

A power line 45 for supplying power to the outlet and a control line 46 for controlling the electromagnetic lock device 40 are connected to a connection terminal in a lowermost control box (not shown) through a wiring duct 47 provided outside the housing.

As in the present invention, in a case where a charging stand having a square cross section and capable of simultaneous charging is provided, and a storage portion of the charging connection device is provided on two adjacent surfaces that are different in level, an upper outlet and a locking device are provided. In addition to the fact that the wiring to the device must pass through the inside of the lower charging connection device, and because the housing itself is narrow, the wiring work for passing the power wiring and the control wiring during manufacturing becomes very difficult. In the present invention, in order to easily and reliably perform the wiring work, a wiring duct is provided on the outer back surface of the rectangular casing as shown in this figure, and the power wiring and the control wiring are passed to the control box.

FIG. 4 shows the storage section 23 of the charging connection device, in which the plug 50 of the charging cable is connected to the outlet 44 and the charging cable 53 including the CCID device 51 is stored in the storage section 23. Since all or a part of the door 26 of the storage unit is made of a transparent material, even after the door 26 of the storage unit is closed, the state in which the charging cable is connected can be confirmed.

Although not shown, the electromagnetic lock device 52 that locks the door 26 of the storage unit is provided with an LED lamp indicating its operating state, so that the lighting state of the LED lamp can be checked through the transparent door.
