View more6 FAQs about [Does the tram have lead-acid batteries ]
What is a battery and accelerating-contact line hybrid tram system?
Extending the work presented in , this study presents a battery and accelerating-contact line (BACL) hybrid tram system where a tram accelerates drawing power from a short contact line (‘ACL’), which can be in the form of a catenary, overhead busbar or third rail. The tram then cruises drawing power from traction battery, as shown in Fig. 2b.
What is the difference between a battery powered tram and a Bacl tram?
Compared to independently battery powered tram, battery size is reduced by 62.5%. Suggested applications for the BACL tram system are on short, fairly flat, idle lines with few stops.
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.
What is a battery powered tram?
The new technology is based on an onboard energy storage system (OBESS), with scalable battery capacity. It can be installed directly on the roof of existing trams - saving on costs, and visual impact – all while ensuring better environmental performance for a more sustainable society. In Florence, battery powered trams have been tested since 2021.
What is traction battery & catenary hybrid tram system?
With such a battery and catenary hybrid tram system, traction battery has to meet peak power demand during acceleration (when a train is leaving a station) on non-electrified section as illustrated in Fig. 2a. Thus, a high capacity high-voltage traction battery is needed.
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.
