4-module low-floor energy storage tram

Can supercapacitor-based energy storage system be used on trams?

To solve technical problems of the catenary free application on trams, this chapter will introduce the design scheme of supercapacitor-based energy storage system application on 100% low floor modern tram, achieving the full mesh, the high efficiency of supercapacitor power supply-charging mode, finally passed the actual loading test [ 8, 9 ].

What is the basic configuration of 100% low floor trams?

The basic configuration of 100% low floor trams is five-car module; the whole train has two motor bogies and one trailer bogie. The vehicle shall meet the track parameters in Table 1. On the mainline and in the depot, the trams use supercapacitor to provide power.

What is the energy storage system of catenary free trams?

On the basis of the research on the energy storage system of catenary free trams, the technology of on-board energy storage, high current charging and discharging and capacity management system has been broken through. The trams with the energy storage system have been assembled and have completed the relative type tests.

Why is energy storage system on trams important?

The energy storage system on the trams has been convinced to meet the requirements of catenary free tram network for both at home and abroad. This technology improves the technical level of domestic tram development greatly and promotes the development of China’s rail tram industry.

How did modern tramways develop a new energy storage system?

In terms of modern tramways, early alternative solutions involved either onboard traction batteries (typically in the form of Nickel-Metal Hydride cells), or onboard supercapacitors. These technologies established a new form of technology, generally termed ‘Onboard Energy Storage Systems’, or OESS.

Are trams a fully low-floor vehicle?

Adapted from Späth and Walcher The technical comparison of currently available trams described in the paper shows that, while different solutions exist, most of the tram designs still belong to the category of fully low-floor vehicles with multi-articulated architecture, in which small-length carbodies and a limited number of bogies are used.
