[Abstract]

　The causes to prevent for spread electric vehicles(EV) are analyzed by hearings, inquiries and driving tests. In a lightweight transportation in a city, the maximum range per charge and the weight of load should be 150km and 2tons, respectively. And in taxies the maximum range should be 350km and 300km, for small sized and midium sized taxi, respectively. Driving test were made by using a lightweight electric truck, an electric mini-car and a prototype electric passenger car. Acceleration and maximum velocities were enough in each car. The energy consumption rate of the electric mini-car was about the half of the same size ICE(internal combustion engine) car. To compare the characteristics of an EV with an ICE car, the items of evaluation are selected. An electric car has advantages on environment and energy, and disadvantages on the driving performances, economics, functions and enjoyment.
