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 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.
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.
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.
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.
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.
Next-generation traction batteries
Sizing the Li-ion batteries is relatively straightforward for tramway applications. As trams run the same route, day-in day-out, an engineer has an accurate estimate of how much power and energy the batteries will require. So, the maths are relatively easy to calculate once the maximum passenger capacity, the temperature range of the local ...

18650 Battery Pack Calculator
To calculate the capacity of a Li-ion battery pack, you sum the capacities of the individual cells in the pack. For example, if you have a pack with four 18650 cells, each with 2600mAh capacity, the pack''s capacity would be 4 * 2600mAh = 10400mAh or 10.4Ah. How many 18650 batteries does it take to make 12V?

How much current does a 48 volt battery in a tram have
A 48-volt battery typically has between 20 and 30 amp hours. The capacity of a battery is often expressed in terms of amp hours, which is the number of amps that the battery can deliver for one hour. A higher amp hour rating means that the battery can store more energy and will last longer before needing to be recharged.
