Equipped with a solar power generation device that includes a light collecting member that collects and irradiates sunlight, a drive device that drives the light collecting member, and a control device that controls the drive device, and that has at least one solar cell panel. A light collecting device that irradiates light to a parked vehicle using a light concentrating member, the control device determining the power generation efficiency of solar power generation by the solar power generation device based on the position of the solar cell panel. The drive device is controlled so that the power generation efficiency is equal to or higher than the initial power generation efficiency that is the power generation efficiency at the initial position of the light collecting member.

Light collecting device

A vehicle management device for managing parking positions in a parking lot of a plurality of vehicles equipped with a solar battery and a power storage device for storing electric power generated by the solar battery, wherein based on the conversion efficiency of the solar battery of each vehicle and the sunlight conditions of the parking lot, the parking position of each vehicle is set so that the amount of solar electric power generation by multiple vehicles per unit time or the sum total of the amount of power generated by the solar cells mounted on multiple vehicles is large. As a result, the amount of electric power generated per unit time and the sum of the amount of electric power generated of the vehicles as a whole can be improved.

Vehicle management device managing parking position in a parking lot and vehicle

A vehicle equipped with a driving unit for traveling, a power storage device capable of supplying power to the drive unit, and a solar cell system capable of supplying power generated by a solar cell to the power storage device. A vehicle management device that determines the cause, based on whether or not a decrease in the amount of power generation has occurred while the vehicle is running and whether or not a decrease in the amount of power generation has occurred while the vehicle is parked, determines whether the decrease in the amount of power generation is caused by the state abnormality of the solar cell or the external environment.
