An electric-vehicle-mounted cooling apparatus is to be mounted in or on an electric vehicle including an electric motor, a first battery, and an inverter. The electric motor is configured to output power for driving. The first battery is configured to store electric power for driving. The inverter is configured to receive the electric power from the first battery and to drive the electric motor. The electric-vehicle-mounted cooling apparatus includes a cooling mechanism and a controller. The cooling mechanism is configured to cool the inverter. The controller is configured to switch a cooling level for the inverter. The inverter is configured to be cooled by the cooling mechanism. The controller is configured to switch the cooling level based on output from the inverter.
