Abstract: In terms of the short group on board energy storage low floor tramcars which were suitable for the small and medium-sized cities, since only charging stations were required for the entire line, no contact system was required in the main line sections, and barely any impacts on the urban landscapes and height limit, thus they were received a rapid development in recent years. However, due to the restrictions from both of the relatively short length of the tramcars and a limited roof installation space, the capacity of their on board energy storage devices were very limited, which resulted in high costs with a large number of charging stations along the lines. In order to increase the capacity of the on board energy storage devices for tramcars, the lithium titanate batteries were adopted to replace the supercapacitors commonly used in tramcars for this research, and the simulations analysis were carried out on Baoshan Tramcar T1 line under the real line conditions. The simulation results show that with the use of lithium titanate batteries instead of supercapacitors, under the same volume, the capacity of the on board energy storage devices may be increased by nearly one time, and the number of inter-section charging may be reduced by nearly half, which reduces the costs of project implementation and later maintenance costs of charging stations.

摘要： 适用于中小城市的短编组车载储能式低地板有轨电车由于全线仅需在车站设充电站，在正线区间不需要架设接触网，对城市景观及限高几乎无影响而在近年得到快速发展，但因短编组有轨电车车长较短，车顶安装空间受限，因此其车载储能装置容量非常有限，导致其在线路沿线设置的充电站数量较多，成本较高。为提高有轨电车车载储能装置容量，采用钛酸锂电池代替有轨电车常用的超级电容并在保山有轨电车T1线实际线路上进行了仿真分析，仿真结果表明，采用钛酸锂电池代替超级电容后，在相同体积下车载储能装置容量可提高近1倍，区间充电站数量约为原数量的1/2，降低了工程实施费用及后期充电站检修维护成本。
