PROBLEM TO BE SOLVED: To provide a charging system that contributes to an appropriate management of commercial power supply by controlling the charging to a secondary battery.SOLUTION: A charging system comprises a charging station and self-traveling equipment in which a secondary battery is built in, the secondary battery that is charged by the charging station. The charging station comprises a power supply circuit that produces electric power for charging from a power source and a power transmission part that transmits electric power for charging to the self-traveling equipment. The self-traveling equipment comprises a power incoming part that receives electric power for charging transmitted from the power transmission part. The charging station or the self-travelling equipment comprises a charge time zone storage part that stores a charge time zone for charging the secondary battery and a charge control part that controls the charging of the secondary battery. The charge control part determines whether the charging of the secondary battery is possible or not in accordance with residual capacity of the secondary battery, and whether the current time is within the charging time zone or not. |
