Description

  The present invention relates generally to a mechanical multistory parking lot, and more particularly to a mechanical multistory parking lot equipped with an electric vehicle charging device.

Currently, global efforts against global warming are underway. In order to reduce carbon dioxide emissions, which is one of the causes, the development of eco-cars with low CO ₂ emissions in relation to transportation, which accounts for 1/4 of CO ₂ emissions, instead of conventional gasoline and diesel vehicles. We are promoting.

Among them, electric vehicles that do not emit CO ₂ while traveling are attracting attention. An electric vehicle is equipped with a storage battery and an electric motor instead of a conventional gasoline engine, and runs using this as a drive source.

  The term “electric vehicle” as used herein refers to a vehicle that is equipped with a storage battery and an electric motor, and that is driven by driving the electric motor with the electric power stored in the storage battery. This includes so-called plug-in hybrid vehicles that use both an engine and an electric motor.

  However, it is said that there are many problems at present in order for the above-mentioned electric vehicles to spread socially. Among them, the major issue along with the price is the development of charging infrastructure.

  This means that the charging distance is often required because the mileage after one charging of the electric vehicle is limited due to the storage battery specification constraints.

  For this reason, electric power companies and electric vehicle manufacturers are planning to install charging devices for electric vehicles. The first place for installation is a parking lot. There are various types of parking lots, such as self-propelled, mechanical, ground, underground, flat, and solid.

  Embodiments of the present invention will be described with reference to the drawings.

[Embodiment 1]
FIG. 1 is a conceptual diagram of a multi-story parking lot to which Embodiment 1 of the present invention is applied. Here, a case where the present invention is applied to an elevator-type comb-tooth type multi-story parking lot is shown.

  As shown in FIG. 1, this multi-story parking lot 1 includes a plurality of parking rooms 2 for storing cars (electric cars 10 and ordinary cars), a lift 3 for carrying cars from the entrance / exit 20 to the height of the parking room 2, A tray 4 for delivering a car from the lift 3 and storing it in the parking room 2 and a lift moving space 5 are provided.

  And in order to charge the electric vehicle 10, the charging device 6, the charging cable 7 for connecting the charging device 6 and the electric vehicle 10, and the charging connector for connecting the charging cable 7 to the charging port of the electric vehicle 10 8 and a charging cable moving mechanism 9 are provided.

  The charging device 6 may have a storage battery inside, and in that case, it is possible to store nighttime electric power with a low electric power unit price and to charge using the electric power. Further, an existing power panel may be used as the charging device 6.

  The charging cable 7 is connected to the charging device 6 and wired to the parking room 2. The charging connector 8 is disposed at a position where it does not interfere with the ordinary vehicle or the parking mechanism when the ordinary vehicle that does not require charging is stored in the parking room 2.

  2 and 3 are views showing the operation of the charging cable moving mechanism 9 in the first embodiment. FIG. 2 shows a state before the electric vehicle 10 is stored, and FIG. 3 shows a state in which the charging connector 8 is moved between the parking room 2 and the entrance / exit 20 when the electric vehicle 10 is stored.

  In the first embodiment, the charging cable moving mechanism 9 includes a slide rail 11, a slide rail moving mechanism (not shown), and a cable reel (not shown).

  When the charging connector 8 is moved to the loading / unloading port 20, if the charging connector 8 is lowered in the state shown in FIG. 2, it interferes with the structure of the multilevel parking garage 1. The slide rail 11 is extended so as to project into the space 5. About 200 to 300 mm is sufficient for the amount of overhang of the slide rail 11 in a general multilevel parking lot.

  Next, the entering / exiting flow of the electric vehicle 10 in this Embodiment 1 is demonstrated. That is, loading and unloading of the electric vehicle 10 is performed by the following procedures (S1) to (S8).

  (S1) When the electric vehicle 10 enters the multi-story parking lot 1, a driver or the like inputs vehicle information of the electric vehicle 10 through an operation panel panel or the like (not shown). At this time, by inputting information such as the manufacturer of the electric vehicle 10 and the vehicle type, it is possible to select the optimal parking room 2 and provide an optimal charging method.

  In addition, information on the optimal charging method may be exchanged between the electric vehicle 10 and the charging device 6 through the connector 8 by a standardized information communication means.

  Further, a device for reading information remotely such as an IC tag may be attached to the electric vehicle 10 and vehicle information may be obtained by a reader attached to the entrance / exit 20 of the multistory parking lot 1 at the time of entry.

  And it is desirable to determine the parking room 2 for storing the electric vehicle 10 from the following concept.

  Here, since the charging connector 8 is disposed on the lift moving space 5 side of the parking room 2, the charging port is on the lift moving space 5 side in order to make the charging cable 7 slack and difficult to contact the electric vehicle 10. It is desirable to store the electric vehicle 10 in the storage. In FIG. 1, when the charging port is on the left side, it is desirable to store in the right parking room, and when the charging port is on the right side, it is preferably stored in the left parking room. There are other electric vehicles with a charging port on the front, but in that case, either the left or right parking room may be used.

  (S2) Next, the charging cable 7 arranged in the parking room 2 is pulled out by the cable moving mechanism 9, and the charging connector 8 is lowered to the entrance / exit 20.

  (S3) After lowering the charging connector 8 to the loading / unloading port 20, the charging connector 8 is connected to the charging port of the electric vehicle 10. It is desirable for the driver himself to make the connection from the viewpoint of trouble avoidance.

  (S4) The electric vehicle 10 to which the charging connector 8 is connected moves to the height of the stored parking room 2 by the lift 3. At this time, the charging cable 7 is wound up by the cable moving mechanism 9 in synchronization with the moving speed of the lift 3. Thereby, the storing operation of the electric vehicle 10 is not affected.

  (S5) The electric vehicle 10 is charged while being stored in the parking room 2. At this time, charging may be started from the stage where the charging cable 7 is connected, or charging may be started after the electric vehicle 10 is stored in the parking room 2.

  (S6) At the time of delivery, information on the electric vehicle 10 to be delivered is given by an operation panel (not shown), and the charging status of the electric vehicle 10 is confirmed. The charging information of the electric vehicle 10 can be added with a system that can be confirmed by a driver from a terminal such as a mobile phone by adding a communication system. When charging is finished and the power is cut off, the exit operation is started immediately. On the other hand, energization is stopped when charging is not completed.

  (S7) Subsequently, the lift 4 moves from the entrance / exit 20 to the parking room 2. The electric vehicle 10 is transferred from the tray 4 to the lift 3 and conveyed to the loading / unloading port 20. At this time, since the charging cable 7 is still connected to the electric vehicle 10, the charging cable 7 is pulled out in accordance with the speed of the lift 3 after the cable moving mechanism 9 protrudes into the lift moving space 5.

  (S8) When the electric vehicle 10 arrives at the loading / unloading port 20, the charging connector 8 is removed. Thereafter, the charging cable 7 is wound up by the cable moving mechanism 9, the cable moving mechanism 9 moves into the parking room 2, and the charging connector 8 returns to a predetermined position in the parking room 2 again, and the next electric vehicle is stored. Prepare for.

  In addition, although this Embodiment 1 has shown the case where it applies to an elevator-type comb-tooth type multistory parking lot as mentioned above, it is applicable also to an elevator type pallet-type multistory parking lot.

  Moreover, not only can it be installed in a new multistory parking lot, but it can also be installed later in an existing multistory parking lot.
