Abstract
A cooling system for an electric vehicle includes: a cooling unit that cools an electric drive unit; and a control unit that controls cooling of the electric drive unit by controlling the cooling unit. The control unit controls the cooling unit in a first cooling mode that provides a first cooling capacity when a force for driving the electric vehicle due to the electric drive unit is in a first operational region, and controls the cooling unit in a second cooling mode that provides a second cooling capacity that is higher than the first cooling capacity when the force due to the electric drive unit is in a second operational region that is higher than the first operational region; and in the second cooling mode, the control unit controls the cooling unit so that the second cooling capacity becomes higher as a rotational speed of the electric drive unit decreases.
