In order to solve EV issues, AI-EV (Air-conditioner Integrated Electric Vehicle) which is integrated with a power source for operating an air-conditioner and traveling a vehicle. In this paper, the authors have examined a method which decreases AI-EV energy consumption for air-conditioner by constructing a heat balance model between the air and the refrigerant at each heat exchanger. In addition, the effect of the air-conditioner performance on the cruising range of the AI-EV and CO_2 emissions when the AI-EV is introduced in the Smart PV and EV system has been evaluated. As a result, due to the improved heat transfer area of a condenser and the effective use of the engine exhaust heat, the COP (coefficient of performance) increased 1.4 times. It was determined that the annual CO_2 emissions are slight difference in the Smart PV and EV system through the use of the AI-EV. On the other hand, the cruising range of an AI-EV with the advanced air-conditioner mounted is able to be extended by more than 25 km in comparison with a conventional AI-EV.
