Cooling system for electric vehicle and control method thereof

摘要

Disclosed are a cooling system for an electric vehicle and a control method thereof. The electric vehicle equipped with electronic parts including an electric motor. The electric vehicle includes a motor control unit to control the electric motor, a main control unit to control the electronic parts and the motor control unit, a water pump to circulate a cooling water cooling the electronic parts, the motor control unit, and the main control unit, and a temperature sensor to detect a temperature for an operation of the water pump and output the temperature to the motor control unit. The motor control unit generates a control signal to operate or stop the water pump according to a detection result of the temperature sensor.

1. An electric vehicle equipped with electronic parts including an electric motor, the electric vehicle comprising:
a motor control unit to control the electric motor; a main control unit to control the electronic parts and the motor control unit; a water pump to circulate water to cool the electronic parts, the motor control unit, and the main control unit; and a temperature sensor to detect temperature and provide the detected temperature to the motor control unit, wherein the motor control unit primarily controls the water pump to operate according to the detected temperature and determines whether the detected temperature is reduced, and wherein the main control unit secondarily controls the water pump to operate if the motor control unit determines that the detected temperature is not reduced after the motor control unit has primarily controlled the water pump to operate.
