Abstract
A solar charging system includes a solar panel, a power conversion unit configured to output electric power generated by the solar panel, a battery configured to be directly charged via the power conversion unit with electric power generated by the solar panel, and one or more processors. The one or more processors are configured to transmit, to the power conversion unit via a communication line, a signal that controls a charge enable or disable status of charging from the solar panel to the battery, and determine whether an abnormality in the communication line is present based on the electric power generated by the solar panel, and a voltage at a middle point between the solar panel and the battery.
