In a charging control system for recording data regarding charging a secondary battery, a status recording unit refers the charging voltage value and the charging current value and records the referred charging voltage, the referred charging current and reference time when the charging current value is referred and time when the charging voltage value is referred, on the recording unit. A battery protecting unit stops the charging the secondary battery when the charging voltage exceeds the predetermined target voltage value. The status recording unit starts recording of the charging voltage value, the charging current value, and the reference time on the recording unit, when the charging voltage exceeds the target voltage value as a result of a fail in stopping the charging by the battery protecting unit because of occurrence of a trouble in the battery protecting unit.
