Nanyue subway station tram energy storage

How did modern tramways develop a new energy storage system?

In terms of modern tramways, early alternative solutions involved either onboard traction batteries (typically in the form of Nickel-Metal Hydride cells), or onboard supercapacitors. These technologies established a new form of technology, generally termed ‘Onboard Energy Storage Systems’, or OESS.

Why do we need stationary energy storage systems?

Since a shared electric grid is suffering from power superimposition when several trams charge at the same time, we propose to install stationary energy storage systems (SESSs) for power supply network to downsize charging equipment and reduce operational cost of the electric grid.

Do catenary-free trams require high charging power?

Abstract: Catenary-free trams powered by on-board supercapacitor systems require high charging power from tram stations along the line.

What are the key features of next generation electrochemical energy storage systems?

For the large-scale grid energy storage systems, wearable power supplies and electrical vehicles, long cycle lifetime, environmental friendliness, high reliability and capacity are required as the key features of next generation of electrochemical ESDs .

Is nice a catenary-free tramway?

Nice was a pioneer of modern catenary-free tramway operation in 2005. Its nickel-based battery system was employed to avoid the visual intrusion of overhead wires in the city, although more modern alternatives have superseded this technology. Neil Pulling

Can lithium batteries be used in a tramway?

The suitability of lithium batteries within a tramway environment is dependent upon the chosen battery chemistry, as there are a large number available, with differing capabilities in terms of performance, safety, and durability.
