A R&D of Battery Powered Wireless Low-floor Tram in South Korea

초록

A wired-wireless hybrid tram with 5-module and 162kwh Li-polymer battery has been developed. The tram can travel over 53km on a single charge without load and wire. Also, its validity has been verified by over 48,000km mileage in the test track. When a full ranged power shipped within urban area, the battery tram avoids high current stress and removes all power infrastructures. Recently, a new 196kwh Li-nano battery pack is developed to be replaced in the same dimension. It can travel over 70km without load and it has longer life cycle. In addition to the battery tram, a test track consisting of 1.5 km embedded rail track and IT based signal has been developed. Under the wireless concept along the line, a tram priority signal has been developed with less signal infrastructures. Also, a sensor based anti-collision system has been developed increasing the safety on the road. The precast slab has been developed for quick construction and the floating slab solution has been developed for less noise.
