Original Abstract Submitted
an object is to provide a controller that makes it possible to efficiently perform temperature control for an electric power converter that converts electric power supplied from a battery while reflecting a deterioration state of the battery. a controller executes output limitation in accordance with a temperature of a refrigerant that cools a power control unit (pcu) serving as an electric power converter, and changes a temperature serving as a criterion for executing the output limitation, in accordance with a deterioration state of a battery . as deterioration in the battery advances, the temperature serving as the criterion for executing the output limitation is lowered.
