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.

    本发明所设计的自动切换流向的电动车水路控制系统,它包括水泵、充电机水套、电机水套、继电器、断水电磁阀和蓄电池,继电器的线圈J1的两端接入充电枪的正负极两端,继电器的常开触点K1的一端连接蓄电池的一极,继电器的常开触点K1的另一端连接断水电磁阀电源的一极,断水电磁阀电源的另一极连接蓄电池的另一极,断水电磁阀控制信号通信端接入继电器的常开触点K1的另一端,断水电磁阀的进水口连接水泵的出水口,断水电磁阀的第一出水口连接电机水套的进水口,断水电磁阀的第二出水口连接充电机水套的进水口,充电机水套的出水口连接电机水套的进水口。本发明避免水阻较大的充电机水套在车辆行驶时接入冷却系统,减少水泵功耗及噪声。
