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 does a battery pack do on a tram?
As the sole power source of the tram, the battery pack can supply power to the traction system and absorb the regenerative braking energy during electric braking to recharge the energy storage system. The traction system mainly consists of the inverter, traction motor, gearbox, and axle.
Why are energy storage trams important?
The modern tram system is an essential part of urban public transportation, and it has been developed considerably worldwide in recent years. With the advantages of safety, low cost, and friendliness to the urban landscape, energy storage trams have gradually become an important method to relieve the pressure of public transportation.
Are trams a sustainable mass transit system?
Once installed trams are one of the lowest energy and most sustainable mass transit systems a city can operate. Much lighter than trains, without the need for often cost prohibitive and energy-intensive underground tunnels that a metro system requires.
How to reduce the energy consumption of trams?
As tram utilization increases, the operational energy consumption of the tram system grows. Therefore, it is crucial to save energy and reduce the energy consumption of trams. One promising approach is to optimize the speed trajectory of the tram, also known as energy-efficient driving [1, 2].
