ABSTRACT:
A charging control apparatus comprising: a voltage control unit in a charging apparatus configured to control generation of an output voltage and a power supply voltage, the charging apparatus being an apparatus configured to generate, from a voltage of an input power supply applied through a relay, the output voltage for charging a battery and the power supply voltage for control; and a relay control unit operated by the power supply voltage, the relay control unit configured to drive the relay so as to stop applying the voltage of the input power supply to the charging apparatus, when detecting a standby state in which the battery is not being charged, and drive the relay so as to increase the power supply voltage by applying the voltage of the input power supply to the charging apparatus, when the power supply voltage decreases below a predetermined level.
