Abstract
To suppress cooling performance from being degraded by bubbles in a coolant in a cooling system for an electric drive vehicle, the cooling system includes: a first coolant circuit through which the coolant for cooling an electric motor and electrical equipment circulates; a first pump that is connected to the first coolant circuit and feeds the coolant; and a first degas tank that is connected to the first coolant circuit and separates the bubbles from the coolant. The first coolant circuit connects the electric motor, the electrical equipment, the first pump, and the first degas tank in series. The first pump and the electric motor are connected in a manner to be sequentially aligned in the first coolant circuit. The coolant flows from the first pump to the electric motor.
