A charging control device that charges a battery (20) using power outputted from a charger (10), wherein a detection means for detecting the voltage and current of the battery (20), a state of charge (SOC) calculation means for calculating the SOC of the battery using the detection values of the detection means, and a charging time calculation means for calculating, on the basis of the SOC calculated by the SOC calculation means, the remaining charging time of the battery (20) until the SOC of the battery (20) reaches a prescribed SOC, are provided. When the charging current drops below a predetermined current threshold value from above the current threshold value, the charging time calculation means calculates the remaining charging time by subtracting the charging time calculated at the point when the charging current becomes less than the current threshold, so as to accommodate the elapsed time from the point when the charging current dropped below the current threshold value.
