    Abstract: A solar charging system includes a first battery, a second battery, and processing circuitry. The processing circuitry charges the second battery by supplying electric power from the first battery to the second battery when a state of charge of the first battery is greater than or equal to a prescribed upper limit value, and charges the first battery by stopping supply of electric power from the first battery to the second battery when the state of charge of the first battery is less than or equal to a prescribed lower limit value. A range from the upper limit value to the lower limit value is a range of use of the first battery. The processing circuitry changes the range of use such that the range of use is wider when a degree of degradation of the first battery is high than when the degree of degradation is low.
