Various methods have been studied recently to save energy consumption in electric railway system. In particular, regenerative brake system has made a contribution to economize a great deal of energy consumption for about thirty years. However, the regenerative brake system in electric railway vehicles has a lot of issues, like as regeneration cancellation by wheel slide and trolley voltage condition, decrease of electric braking force in high speed range, and restriction of regenerative power determined by impedance of power supply circuit. In order to utilize and re-cycle braking energy and secure steady regenerative load, we selected lithium ion battery as electric energy storage equipment, and developed a rechargeable lithium ion battery (600V system) for electric railway vehicles. The developed battery has a superior performance as high energy and power density, high efficiency, 500A charge-and-discharge current, long cycle life, and less loss and maintenance work. In this report, we show an energy re-cycling trolley-less tramcar using the rechargeable lithium ion battery as on-board energy storage equipment, and show results of the tramcar performance and the developed battery characteristics.
