摘要
A charging circuit charges a secondary battery by using a first direct current power supply that generates and outputs a first voltage. A highest voltage among the first voltage of the first direct current power supply, a second voltage generated from power supplied from outside, and a secondary battery voltage of the secondary battery is supplied as a power supply to the charging circuit.
