The invention relates to an electric vehicle waterway control system capable of automatically switching flow directions. The system comprises a water pump, a charger water jacket, a motor water jacket, a relay, a water cut-off electromagnetic valve and a storage battery. The two ends of a coil J1 of the relay are connected to the positive and negative ends of a charging gun; one end of a normallyopen contact K1 of the relay is connected with one pole of the storage battery; the other end of the normally open contact K1 of the relay is connected with one pole of the water cut-off electromagnetic valve power supply, the other pole of the water cut-off electromagnetic valve power supply is connected with the other pole of the storage battery, a control signal communication end of the water cut-off electromagnetic valve is connected to the other end of the normally open contact K1 of the relay, and a water inlet of the water cut-off electromagnetic valve is connected with a water outlet of the water pump; and a first water outlet of the water cut-off electromagnetic valve is connected with a water inlet of the motor water jacket, a second water outlet of the water cut-off electromagnetic valve is connected with a water inlet of the charger water jacket, and the water outlet of the charger water jacket is connected with a water inlet of the motor water jacket. The charger water jacket with a large water resistance is prevented from being connected into a cooling system when a vehicle runs, and the power consumption and the noise of the water pump are reduced.
