Abstract
A charge support system is provided for a plurality of autonomously movable vehicles, each including a solar cell panel and a storage battery for storing electricity from the solar panel. The system includes an acquisition unit that obtains information regarding vehicles parked within a predetermined parking area, including charging efficiencies of the solar panels, current charging rates of the storage batteries, and scheduled driving times for each vehicle. A traveling control unit is configured to move the vehicles within the parking area based on the acquired information. The system prioritizes movement of vehicles with earlier scheduled driving times to areas of higher charging efficiency to ensure their storage batteries reach a predetermined charge threshold. Additionally, for vehicles without scheduled driving times, the system periodically moves the vehicles to equalize battery charge levels within a specified error range. This enables efficient solar charging across multiple vehicles in a shared parking environment.
