Beschreibung
Zusammenfassung:	Provided is an electric vehicle (10) includes a power control unit (14), a driving motor (16), a first cooling channel fitted with a first pump (28) that causes a first cooling liquid cooled in a first heat exchanger (20) to flow through the power control unit (14) and a second heat exchanger (26) in this order and return to the first heat exchanger (20), and a second cooling channel fitted with a second pump (32) that causes a second cooling liquid cooled by the first cooling liquid in the second heat exchanger (26) to flow through the driving motor (16) and return to the second heat exchanger (26). The second pump (32) starts or stops circulation of the second cooling liquid, or increases or reduces a circulation volume of the second cooling liquid, based on one or both of the temperature of the power control unit (14) and the temperature of the first cooling liquid.
