6 FAQs about [Emergency energy storage tram]
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 long does a tram stay on a battery?
The tram dwells for 45 s at an intermediate station, and if there is a battery charging infrastructure (a contact line in this case) at the station, the battery pack is recharged. When the tram reaches the terminal station, the battery pack is to be recharged to full charge.
Why should you choose a battery-driven tram?
This will help to reduce the required traction power, energy, and consequently battery capacity. Owing to advancements in battery technology, battery performance has been improving while the cost is going down, this keeps increasing the attractiveness of a battery-driven tram on short and idle routes.
Where is tram braking energy stored?
The tram braking energy is to be stored in WESD which in turn will be feeding the charging point. The charging points are to be installed in car parks in the close vicinity of tram stations to encourage people to use the public transport. Figure 14. Feeding arrangement with charging point and WESD.
Does a tram have a battery pack?
A battery pack is the sole tram power supply and there is no battery charging at intermediate stations. For cases 1Up, 1Down, 2Up, and 2Down, when a tram is in the electrified zone (a zone with contact line), all tram power demands are drawn from the contact line, and also a battery pack is recharged.
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.
