  6. The mechanical parking system according to any one of claims 1 to 5 , wherein the control device terminates charging of the vehicle without waiting for the predetermined termination condition to be met when a predetermined charge rate or predetermined remaining capacity is reached.
  7. The mechanical parking system according to claim 6 , wherein the control device, when it has finished charging the vehicle due to reaching a predetermined charge rate or a predetermined remaining capacity, puts the vehicle into a fully charged state.
  8. The mechanical parking system according to claim 7 , wherein the control device puts a vehicle into a waiting state for recharging when predetermined recharging conditions are met for a vehicle that is already charged.
  9. The mechanical parking system according to claim 8, wherein the recharging conditions are any of the following: a predetermined period of time has elapsed since the system was fully charged; the charge rate has fallen below a predetermined rate; or the remaining capacity has fallen below a predetermined amount.
  10. A program to be executed by a control device for a mechanical parking garage that can charge a vehicle while parked, The mechanical parking system comprises a plurality of pallets on which vehicles are mounted, a plurality of parking spaces, each accommodating a pallet, including charging parking spaces where chargers are installed and non-charging parking spaces where chargers are not installed, and a transport device for moving the pallets between the parking spaces. This program enables the control device to implement the functions of charging the vehicle by the charger and controlling the operation of the transport device. The control function described above is The vehicle parked in the charging parking space is charged, and when the predetermined termination conditions are met, the charging of the vehicle is terminated, and the transport device moves another vehicle waiting to be charged to the charging parking space and starts charging it . A computer program that, upon completion of vehicle charging due to the fulfillment of the predetermined termination conditions, puts the vehicle into a state of waiting to recharge .

Description

This invention relates to a parking lot. Low-noise and clean electric vehicles and plug-in hybrid vehicles (hereinafter collectively referred to as EVs) are beginning to become widespread. EVs are powered by electricity from secondary batteries such as lithium-ion batteries. Recently, technologies have been proposed to charge the secondary batteries of EVs while they are parked (for example, Patent Document 1). Japanese Patent Publication No. 2012-241344 This is a diagram illustrating the configuration of a parking system according to an embodiment.Figure 1 is a front view of the parking lot.Figure 2 is a floor plan of the parking area.This block diagram shows the functions and configuration of the control device shown in Figure 1.Figure 4 shows an example of the data structure of the charging management information storage unit.This figure shows an example of the data structure of the usage status retention unit in Figure 4.This block diagram shows the functions and configuration of the server in Figure 1.Figure 7 shows an example of the data structure of the parking information storage unit.Figure 1 is a block diagram showing the functions and configuration of the mobile terminal.This figure shows an example of a screen displaying information about nearby parking lots.This figure shows another example of a nearby parking information screen.This is a flowchart explaining the operation of a parking lot.This is a sequence diagram explaining the operation of the server. In the following drawings, identical or equivalent components and members will be denoted by the same reference numerals, and redundant explanations will be omitted as appropriate. Furthermore, the dimensions of the members in each drawing will be enlarged or reduced as appropriate for ease of understanding. Additionally, some members that are not essential to explaining the embodiment will be omitted from each drawing. Parking lots that allow charging while parked are becoming more common. These parking lots generally have fewer chargers than parking spaces due to cost and other reasons. Therefore, depending on the parking lot's usage—specifically, the number of EVs wishing to charge while parked—you may not be able to charge immediately after entering the lot, and you may have to wait for a charger to activate. Incidentally, the time required to fully charge an EV varies greatly depending on the maximum capacity, remaining capacity, and charging performance of the EV's secondary battery. For example, charging an EV with a large maximum capacity and low remaining capacity takes a long time (e.g., 8 hours or more). Therefore, if the conventional method of switching EVs once they are fully charged is adopted, the chargers will be monopolized by EVs that take a long time to fully charge, as described above, resulting in EVs being parked for extended periods without being charged. This inevitably creates a sense of unfairness among users. Therefore, in this embodiment, when a predetermined termination condition is met, such as "the maximum charging time (e.g., 30 minutes) has elapsed," charging of the EV is terminated, and charging of another EV that is waiting to be charged is started. A detailed explanation follows below. Figure 1 is a schematic diagram showing the configuration of a parking system 1 according to an embodiment. The parking system 1 comprises multiple parking spaces 100, a server 200, and multiple mobile terminals 300. Each device in Figure 1 is connected via a network 2. The number of parking spaces 100 and mobile terminals 300 is not limited to the example shown in Figure 1. Parking lot 100 may be a parking lot for an apartment building or other multi-unit dwelling, a parking lot for a commercial facility such as a department store, or a parking lot for a public facility such as a city hall. Parking lot 100 may be a parking lot for vehicles of regular contract holders, a time-based parking lot (i.e., a parking lot for temporary users), or a parking lot for vehicles of both regular contract holders and temporary users. Parking lot 100 is a parking lot with multiple parking spaces. Each parking space is a single parking area where one vehicle can be parked. In other words, parking lot 100 is a parking lot capable of accommodating multiple vehicles. Parking lot 100 is equipped with one or more chargers for charging the secondary batteries of EVs (hereinafter also simply referred to as "charging EVs"). In other words, parking lot 100 is a parking lot where EVs can be charged while parked. EVs may be manually driven vehicles or autonomous vehicles. For cost and other reasons, parking lot 100 is equipped with fewer chargers than the number of parking spaces. In this embodiment, parking lot 100 is a pallet-type mechanical parking system. As will be described in more detail later, in parking lot 100, an EV is loaded onto a pallet compatible with charging (hereinafter also referred to as a "charging pallet") in the passenger compartmen
