A novel concept of AI-EV (air-conditioner integrated electric vehicle) for the advanced smart community

Abstract

Paper presented to the 10th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Florida, 14-16 July 2014.

After the Great East Japan Earthquake, it has become necessary to reduce nuclear power dependence and CO2 emissions. In one of the solutions, a Smart PV & EV System which is combined the photovoltaic power generation (PV) and electric vehicle (EV) system has been proposed. In the system, it is not only to improve the energy efficiency of a car, but also to reduce the CO2 emissions from the total energy consumption of homes, vehicles and the work places. In the Smart PV & EV System, it is important that EV becomes popular. In order to spread and expand EV, it should solve the issues of short cruising range, the high cost of storage battery and the risk of dead battery. Therefore, the authors have proposed Air-conditioner Integrated Electric Vehicle (hereinafter referred to as AI-EV). In this paper, a car air-conditioner capacity is determined based on the heat transfer between inside and outside of the car. A mathematical simulation model which evaluates for the AI-EV energy consumption has been developed. And then, the value of the AI-EV is compared with a gasoline vehicle, hybrid vehicle (hereinafter referred to as HV) and EV using the mathematical simulation model. In the comparison, CO2 emissions, the amount of energy consumption and economic efficiencies are evaluated in the Smart PV & AI-EV System. In addition, the performance of AI-EV as a vehicle is compared with the conventional EV. As a result, it is clarified that the minimum displacement of the small-engine is 120 cc for AI-EV. In the Smart PV & AIEV System, AI-EV is expected to reduce CO2 emissions of 20% which is compared with a gasoline vehicle. The effect is almost the same as EV. Additionally, the performance of AI-EV as a vehicle in a city area, AI-EV is able to gain the maximum cruising range approximately twice as long as EV. As the results, AI-EV can solve the issues of conventional EV. Therefore, it is considered that the Smart PV & AI-EV system can be adapted for Europe and America that is long commuting distances of over 50 km for one way.
