    • PURPOSE: A cooling water shortage detecting and warning device for a hybrid vehicle and a method thereof are provided to induce vehicle maintenance in early times and to prevent the vehicle from being abnormally driven by rapidly informing a driver of cooling water shortage. CONSTITUTION: A cooling water shortage detecting and warning device for a hybrid vehicle comprises a current measurement sensor, a controller, and a cluster warning lamp(13). The current measurement sensor measures the consumed current of a water pump(14). The controller receives a signal from the current measurement sensor and controls on or off of the cluster warning lamp. The cluster warning lamp is installed on a cooling water temperature dashboard of a cluster and informs a driver of cooling water shortage.

    • PURPOSE: An electric vehicle cooling system and an operation method thereof are provided to prevent the durability deterioration of an electric water pump by temporarily stopping the operation of a system when exceeding the acceptable standards of a normal operation through the self-diagnosis of the electric water pump. CONSTITUTION: An electric vehicle cooling system comprises an electric power plant(1), a radiator(5), an electric water pump(7), a cooling water line(8), and a cooling system protection unit. The electric power plant exchanges heat with the cooling water which passes the inside in order to prevent overheating. The radiator exchanges the heat of the high temperature cooling water with the outside. The electric water pump pumps the cooling water out of a reservoir(6) which is connected to the radiator for discharging the cooling water to the electric power plant. The cooling water line forms the flowing route of the cooling water which circulates through the operation of the electric water pump. The cooling system protection unit performs self-diagnosis logic for repeating the temporary stop mode of the electric water pump when the self-diagnosis result safely exceeds a predetermined level or stopping the operation of the electric water pump when the self-diagnosis result unsafely exceeds the predetermined level.
