Tram investment in energy storage

How do energy trams work?

At present, new energy trams mostly use an on-board energy storage power supply method, and by using a single energy storage component such as batteries, or supercapacitors.

How much energy does a tram use?

The greater the distance between stations, the greater the demand energy. The first interval has the largest distance and maximum energy consumption. If the recovered braking energy is not included, the energy consumption is 7.012 kwh. Fig. 3. DC bus demand energy curve. The tram adopts the power supply mode of catenary free and on-board SESS.

Can EV batteries be used as energy storage for tram networks?

This research considers using the EV battery as energy storage for the tram network is a promising option that could lead to better economic feasibility. Still, to provide a more reliable and comprehensive feasibility study for this exploitation, it requires further research on

How much energy does a MTS tram use?

In MTS trams, the Ni-MH battery features rated energy and power of 18 kWh and 85 kW, respectively, while the supercapacitors' rated power output is 288 kW. The total weight of the hybrid storage system is 1646 kg, resulting in specific energy and power of 11.45 Wh/kg and 226 W/kg, respectively.

Are energy trams better than buses?

The new energy trams have significantly higher passenger capacity than buses, significantly lower investment prices, and lower construction cycle than the metro.

What power supply mode does a tram use?

The tram adopts the power supply mode of catenary free and on-board SESS. The whole operation process is powered by a SESS. The SESS only supplements electric energy within 30s after entering each station. The power supply parameters of the on-board ESS are shown in Table 2. Table 2. Power supply parameters of on-board ESS.
