Claim:
1. An electrically driven vehicle comprising: a vehicle body provided with a vehicle interior; a battery which is mounted to the vehicle body and is usable for running; an electric motor which is supplied with electric power from the battery and rotates an output shaft, a rotation output of the output shaft being transmitted to drive wheels via a transmission; a first air conditioning unit which executes an air-conditioning operation which uses the electric power of the battery when air-conditioning the vehicle interior; a power generation device that includes a power generator and an engine to drive the power generator with fuel and is at least partly removably mounted to the vehicle body, electric power generated by the power generator being used to charge the battery, the power generation device being a second air conditioning unit that executes an air-conditioning operation other than the air-conditioning operation which uses the electric power of the battery when air-conditioning the vehicle interior, the electrically driven vehicle being configured to operate by the battery even when the power generation device is not mounted in the electrically driven vehicle and an electric connection with the power generation device is cut in order to suppress a decrease in energy efficiency due to an increase of weight from the power generation device; a mount detection sensor to detect mount/unmount of the power generation device; and an air conditioning change unit which changes at least one of use states of the first air conditioning unit and the second air conditioning unit on the basis of the mount/unmount of the power generation device detected by the mount detection sensor, and selects the first air conditioning unit when the mount detection sensor detects unmount of the power generation device, wherein the second air conditioning unit executes at least one of an air-conditioning operation which uses waste heat of the engine and another air-conditioning operation which uses heat released from a cooling medium to cool the engine.
