PROBLEM TO BE SOLVED: To provide a charging system for an electric vehicle, capable of preventing breakage of a smoothing capacitor of a charger without deteriorating charging efficiency in charging an on-vehicle storage battery of the electric vehicle. SOLUTION: A connector 13 connects the charger 17 to the on-vehicle storage battery 14, and the charger 17 converts the power of an AC power supply 15 into DC power and charges the on-vehicle storage battery 14 of the electric vehicle 12. A parallel circuit of a resistor 28 and a resistance bypass contactor 29 is connected in series to a smoothing capacitor 25 provided in an output section of the charger 14. A DC breaker 18 connected between the charger 17 and the connector 13 is closed when the charger 17 start to charge the on-vehicle storage battery 14 and is opened in charging completion or in emergency. The resistance bypass contactor 29 is closed during energization from the charger 17 to the on-vehicle storage battery 14 and is opened in charging completion or in emergency.
