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.
To minimise total electrified distance and traction battery size, a battery and accelerating-contact line (BACL) hybrid tram system in which a tram accelerates from a station drawing power from a short contact line and cruises with traction battery is presented.
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.
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.
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.
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.
