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.
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.
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.
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.
In such cases, battery powered trams present a promising alternative. Rail vehicles are heavy but, they have a low coefficient of rolling friction. Consequently, they draw high power during acceleration as compared to the power demand during cruising. Thus, a high capacity high-voltage traction battery is required to provide accelerating power.
In Florence, battery powered trams have been tested since 2021. Fitted to trams on the existing Sirio fleet, the battery technology enables the trams to operate on a section of the line entirely under battery power, without the use of overhead infrastructure.
