The above and other objects, features and advantages of the present disclosure will become more fully understood from the detailed description given hereinbelow and the accompanying drawings which are given by way of illustration only, and thus are not to be considered as limiting the present disclosure.
The present disclosure will be described hereinafter with reference to an embodiment of the present disclosure. However, the following embodiment is not intended to limit the scope of the disclosure according to the claims. Further, all the components/structures described in the embodiment are not necessarily indispensable as means for solving the problem. For the clarification of the description, the following descriptions and the drawings are partially omitted and simplified as appropriate. The same elements are denoted by the same reference numerals or symbols throughout the drawings, and redundant descriptions are omitted as necessary.
As shown in
All of the vehicles 20_1 to 20_n are parked within a predetermined parking area. For example, the vehicles 20_1 to 20_n are test vehicles parked within a parking area of a car dealer. Alternatively, the vehicles 20_1 to 20_n are rental cars parked within a parking area of a car rental store.
The communication apparatus 21_1 communicates with the charge support apparatus 10 (more specifically, a communication unit 11 of the charge support apparatus 10 described below) through the network 50.
The solar cell panel 22_1 is a panel that generates electricity by sunlight and is attached to a part of a vehicle body of the vehicle 20_1. For example, the solar cell panel 22_1 is attached to a roof, a hood, a door, or the like of the vehicle 20_1. In the present embodiment, a case in which the solar cell panel 22_1 is attached to the roof of the vehicle 20_1 will be described as an example.
The storage battery 23_1 is connected to the solar cell panel 22_1 via the charging cable 24_1 to store electricity generated by the solar cell panel 22_1. The storage battery 23_1 can be used as a backup power source or as a power source if the vehicle 20_1 is an electric vehicle.
In
The communication unit 11 communicates with each of the communication apparatuses 21_1 to 21_n of the vehicles 201 to 20_n through the network 50.
For example, the communication unit 11 receives information about charging efficiencies and charging rates of the storage batteries 231 to 23_n transmitted from the communication apparatuses 21_1 to 21_n of the respective vehicles 20_1 to 20_n, and transmits a traveling instruction to each of the vehicles 20_1 to 20_n.
The acquisition unit 12 periodically acquires, through the communication unit 11, at least information about charging efficiencies of the storage batteries 23_1 to 23_n by electricity generated by the solar cell panels 22_1 to 22_n and information about charging rates of the storage batteries 23_1 to 23_n. Here, the information about charging efficiency of the storage battery by electricity generated by the solar cell panel is, for example, output voltage of the solar cell panel, which corresponds to the amount of charge of storage battery per unit time.
Further, the acquisition unit 12 may be configured to further acquire information about the scheduled driving time of a driver of each of the vehicles 20_1 to 20_n via the communication unit 11.
The traveling control unit 13 moves the vehicles 20_1 to 20_n within a range of the predetermined parking area based on the information acquired by the acquisition unit 12.
For example, in a case in which the charging rate of the storage battery 23_1 of the vehicle 20_1 is greater than or equal to a predetermined rate and the charging rate of the storage battery 23_2 of the vehicle 20_2 is less than a predetermined rate, when the charging efficiency of the storage battery 23_1 is higher than the charging efficiency of the storage battery 23_2, the traveling control unit 13 controls the vehicle 20_1 and the vehicle 20_2 so that they automatically drive so as to exchange the parking position of the vehicle 20_1 with the parking position of the vehicle 20_2. That is, the traveling control unit 13 moves the vehicle 20_2 whose charging rate of the storage battery is low to an area where a charging efficiency is high. It should be noted that, in general, a charging efficiency of a storage battery mounted in a vehicle parked in a sunny area is high, while a charging efficiency of a storage battery mounted in a vehicle parked in a shady area is low.
Alternatively, in a case in which the charging rate of the storage battery 23_1 of the vehicle 20_1 and the charging rate of the storage battery 232 of the vehicle 20_2 are both less than a predetermined rate, when the scheduled driving time of a driver of the vehicle 20_1 is earlier than the scheduled driving time of the vehicle 20_2, the traveling control unit 13 moves the vehicle 20_1 preferentially over the vehicle 20_2 to an area where a charging efficiency is high. However, if the charging rate of the storage battery 231 reaches or exceeds a predetermined rate by the scheduled driving time of the driver of the vehicle 20_1, the traveling control unit 13 may not move the vehicle 20_1.
For example, when the scheduled driving time of the driver of each of the vehicles 20_1 to 20_n is not specifically determined, the traveling control unit 13 may move the vehicles 20_1 to 20_n periodically so that the charging rates of the storage batteries 23_1 to 23_n of the respective vehicles 201 to 20_n are equal to each other within a predetermined error range.
As described above, the charge support system 1 according to the present embodiment can efficiently charge the storage batteries 23_1 to 23_n respectively mounted on the vehicles 20_1 to 20_n parked within a predetermined parking area by moving the vehicles 20_1 to 20_n within a range of the predetermined parking area based on charging efficiencies, charging rates, and the like of the storage batteries 23_1 to 23_n respectively mounted on the vehicles 20_1 to 20_n.
Next, the operations of the charge support apparatus 10 will be described with reference to
First, the charge support apparatus 10 periodically acquires information about charging efficiencies of the storage batteries 231 to 23_4 of the respective vehicles 20_1 to 20_4 by electricity generated by the solar cell panels 22_1 to 22_4 and information about charging rates of the storage batteries 23_1 to 23_n of the respective vehicles 201 to 20_4 (Step S101). In addition, the charge support apparatus 10 may further acquire information about a scheduled traveling time of a driver of each of the vehicles 20_1 to 20_4.
In an example shown in
At this time, the charge support apparatus 10 acquires information indicating that the charging efficiency of the storage battery 23_1 is high and the charging efficiencies of the storage batteries 23_2 to 23_4 are low, and also acquires information indicating that all the charging rates of the storage batteries 23_1 to 23_4 are less than a predetermined rate. It should be noted that, as a matter of course, the charge support apparatus 10 may acquire specific numerical values of the charging efficiency and the charging rate of each of the storage batteries.
Then, in an example shown in
When the charge support apparatus 10 acquires information that charging rate of the storage battery 23_1 has reached a predetermined rate, the charge support apparatus 10 moves the vehicles 201 to 20_4 within a range of the parking area 100 based on the acquired information (Step S102).
In the example shown in
As described above, the charge support system 1 according to the present embodiment can efficiently charge the storage batteries 23_1 to 23_n respectively mounted on the vehicles 20_1 to 20_n parked within a predetermined parking area by moving the vehicles 20_1 to 20_n within a range of the predetermined parking area based on charging efficiencies, charging rates, and the like of the storage batteries 23_1 to 23_n respectively mounted on the vehicles 20_1 to 20_n.

Further, the present disclosure relates to use of a solar photovoltaic panel, and contributes to carbon neutrality, decarbonization, and Sustainable Development Goals (SDGs).
Further, in the present disclosure, it is possible to implement all or part of processing performed by the charge support apparatus 10 by causing a Central Processing Unit (CPU) to execute a computer program.
The above-described program includes instructions (or software codes) that, when loaded into a computer, cause the computer to perform one or more of the functions described in the embodiment. The program may be stored in a non-transitory computer readable medium or a tangible storage medium. By way of example, and not a limitation, non-transitory computer readable media or tangible storage media can include a Random-Access Memory (RAM), a Read-Only Memory (ROM), a flash memory, a Solid-State Drive (SSD) or other types of memory technologies, a CD-ROM, a Digital Versatile Disc (DVD), a Blu-ray (Registered Trademark) disc or other types of optical disc storage, and magnetic cassettes, magnetic tape, magnetic disk storage or other types of magnetic storage devices. The program may be transmitted on a transitory computer readable medium or a communication medium.
