Description

This disclosure relates to a parking management system, and more specifically, to a parking management system that manages the movement of multiple movable pallets carrying vehicles into parking spaces. Conventionally, this type of parking management system has been proposed to include a stationary battery installed in the parking lot and multiple charging and discharging stations for charging and discharging batteries mounted on electric vehicles (see, for example, Patent Document 1). In this system, even when the power grid is in an emergency, power is supplied to the first load from at least one of the stationary battery and the multiple charging and discharging stations. This ensures that a predetermined power supply can be provided to the first load even when the power grid is in an emergency. Japanese Patent Publication No. 2020-010442 This is a schematic diagram showing the general configuration of the parking management system 20 as an embodiment of the disclosure.This diagram shows a schematic configuration of vehicles that can utilize the charging and discharging parking spaces 32 in the parking lot 30.This flowchart shows an example of a pallet movement process performed by the electronic control unit 60.This is a schematic diagram showing the general configuration of the modified parking lot 30B. Next, an embodiment for implementing this disclosure will be described. Figure 1 is a schematic diagram showing the configuration of a parking management system 20 as an embodiment of this disclosure. As shown in the figure, the parking management system 20 of the embodiment comprises a plurality of pallets 40 that are arranged in each parking space of the parking lot 30 and are movable with vehicles mounted on them, a plurality of charge/discharge devices 33 installed in the chargeable/dischargeable parking spaces 32 of the parking lot 30, a plurality of charge devices 35 installed in the rechargeable parking spaces 34 of the parking lot 30, a power supply circuit 50, and an electronic control unit 60. The parking lot 30 includes charging/discharging parking spaces 32, charging-enabled parking spaces 34, and general parking spaces 36. The charging/discharging parking spaces 32 are located in the area of the parking lot 30 closest to the designated facility 10, and each parking space is equipped with a charging/discharging device 33 for charging and discharging the battery installed in the vehicle. The reason why the charging/discharging parking spaces 32 are located in the area of the parking lot 30 closest to the designated facility 10 is to minimize power loss when supplying power from the batteries installed in the electric vehicles parked in each parking space of the charging/discharging parking spaces 32 to the designated facility 10. The charging/discharging parking spaces 32 are divided into a first parking space 32a (upper parking space in Figure 1) which is close to the designated facility 10, and a second parking space 32b (lower parking space in Figure 1) which is farther from the designated facility 10. While the designated facility 10 is described using an airport as an example, it could also be a large leisure facility with a hotel, a shopping center, a train station, a port, or other similar structure. The rechargeable parking spaces 34 are located in the area of the parking lot 30 that is further from the designated facilities 10 than the rechargeable parking spaces 32. Each parking space is equipped with a charging device 35 that can only charge the battery installed in the vehicle. The general parking spaces 36 are located in the area of the parking lot 30 that is furthest from the designated facilities 10, and neither rechargeable/dischargeable devices 33 nor charging devices 35 are installed in these spaces. Each pallet 40 within the parking lot 30 is equipped with a moving mechanism (not shown) that allows it to be moved to its respective parking space while a vehicle is loaded on it. This movement is controlled by an electronic control unit 60. The power supply circuit 50 is installed between the rechargeable parking spaces 32 of the parking lot 30 and the designated facility 10. The power supply circuit 50 is connected to each charge/discharge device 33 in the rechargeable parking spaces 32 via power line 52, and to each charge device 35 in the rechargeable parking spaces 34 via power line 54. Furthermore, the power supply circuit 50 is connected to the electrical equipment (not shown) of the designated facility 10 via power line 56, and to other power sources 12 via power line 58. The other power sources 12 are configured to include at least a portion of various power sources, such as commercial power, solar power, wind power, tidal power, and geothermal power. The power supply circuit 50 is configured to adjust the voltage of the power supplied from the other power sources 12 and supply it to the designated facility 10, the charge/discharge devices 33, and the charge devices 35
