摘要：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 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. One major problem in realizing this system is the development of the charge-boosting system. And lightning of the storage device mounted on the bus is also key problem. We therefore begin by examining the features of typical storage devices. Next, we investigate issues involving the design of the charge-boosting system at the bus stop and the storage device on the bus. Finally, we perform a model experiment using a single-passenger electric vehicle. We find that a vehicle containing a designed storage device and running on electric power generated from solar energy can repeat the cyclical operation of running for approximately 90 s, stopping 20 s for charge, and accelerating fully charged from the bus stop for 4 s. The result is that the model experiment validates the proposed transport system design.
