Abstract

\“The Solar Light Rail” is a proposed power supply method for a 100% renewable energy light rail system. Experiments using a prototype model were carried out in all four seasons in order to verify whether the proposed system can function e ectively throughout the day. The primary electric double layer capacitor (EDLC) unit, with a breakdown voltage of 17.5 V and a capacitance of 171.4 F, is charged by solar panels. The secondary EDLC unit which has a breakdown voltage of 15.0 V and a capacitance of 100 F is mounted on the railcar and is charged rapidly by the primary EDLC. The railcar leaves and returns on a straight rail of 9 meters by charged energy, and the secondary EDLC is charged from the primary EDLC again. It was confirmed that the proposed power supply method was e ective even in a climate with little or no sunshine, and also that it is necessary to raise the breakdown voltage and capacitance of the primary EDLC to ensure long-term operation after sunset.
