Can electric trams use supercapacitors for energy storage?

While many cities are using electric trams and buses, this is one of the first in the world to use supercapacitors for energy storage, and plans are afoot to expand the service even further. One of the world’s first electric trams using supercapacitors for energy storage has been implemented in Huai’an.

What is a battery powered tram?

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.

How is a tram powered?

Trams are typically powered by an overhead contact line with a 750 or 600 V DC power supply wire at 4 to 6 m above the rail level. The electric current returns through the rails, and all metallic parts of the vehicles must be earthed to ensure safety against accidental electrocution.

How long does an electric tram take to recharge?

State-of-the-art battery technology enables electric trams to fully recharge in just 30 seconds. With a 20 km long route, Huai’an has introduced the longest running electric tram using supercapacitors in the world.

How will a supercapacitor tram affect the environment?

Environment The supercapacitor tram will reduce annual hydrocarbon and NOx emis- sions by 196 and 490 tons respectively, improving air quality for the city’s 5.7 million citizens. Health Shifting journeys from private cars to low-carbon trams not only reduces the chance of respiratory illness, but also encourages more active lifestyles in the city.

What power source do trams typically use?

Trams generally use an overhead contact line with a 750 or 600 V DC power supply wire at 4 to 6 m above the rail level. The electric current returns through the rails.
