Abstract
A power source system includes a first power source, a power generator, a first electrical load, a second electrical load, a second power source, and a charge/discharge switch provided between the second power source and the power generator. The charge/discharge switch is controlled into a closed state to electrically connect the power generator to the second power source, when an amount of charge of the second power source is less than a charge request threshold, the power generator is in a power generating state, and an amount of power generated by the power generator is equal to or more than a total power requirement as a total sum of respective amounts of power required by the second power source, the first electrical load, and the second electrical load.
