Charging apparatus, program

A charging apparatus includes: a charging circuit (31) configured to charge a secondary battery (15); and a control circuit (32) configured to control an operation of the charging circuit (31), the control circuit (32) including a control unit configured to control the charging circuit (31) so that the secondary battery (15) is charged with a constant current until a time when a battery voltage of the secondary battery (15) goes to a first voltage, control the charging circuit (31) so that the secondary battery (15) is charged with a current smaller than the constant current when the battery voltage goes to the first voltage, and control the charging circuit (31) so that the secondary battery (15) is charged with a constant voltage when the battery voltage goes to a second voltage higher than the first voltage.
