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.
