In a sustainable city, public transportation is prohibited from emitting greenhouse gasses. To reduce emissions of carbon dioxide, a major greenhouse gas, a vehicle running on electric power generated from a green energy source is optimal because it does not emit carbon dioxide. With this goal in mind, we propose a public transport system consisting of electric buses that are quickly charged intermittently at every bus stop using electric power generated from green energy sources. Such a system resolves the problem of low mileage per charge for heavy batteries. This system would also be able to effectively use low-density and widely available solar energy for generating power at bus stops that are widely distributed throughout a city. In this paper, we first introduce an electric bus system that is rapidly charged at every bus stop using electric power generated from green energy sources. We then report results of a demonstration experiment using an EV converted minivan, which allows changing the number of passengers.
