Abstract
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.
