What is the tram and vehicle energy storage system

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.

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 ].

Can EVs be used for energy storage in a tram network?

Using EVs for energy storage to the tram network could be more advantageous on the economic feasibility than the stationary ESS, but work is still ongoing in this area. The work presented can be generalised to any tram network through the adoption of the processes outlined in the paper for the specific network.

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.

Does the ESS provide its own energy to the tram?

Conversely, if the increase of E reg is less than the reduction of energy from E sub, then the ESS provides its own energy to the tram.

Could EV battery be used as ESS for the tram network?

However, exploiting an EV battery as the ESS for the tram network is expected to contribute additional operating cycles to the EV battery which could potentially degrade the battery life quicker than seen in normal EV use.
