Abstract
A detector detects a remaining power of a battery. A calculator calculates a demand load of air-conditioning based on at least one of a preset temperature set for air in a passenger compartment of an electric vehicle and an outside temperature of air outside of the electric vehicle. A switching portion switches a mode of air-conditioning between a battery mode and an engine mode based on the calculated demand load and the detected remaining power of the battery. The battery mode causes the battery to supply electric power for air-conditioning, and the engine mode causes an engine of the electric vehicle to supply combustion energy for air-conditioning.
