Tram energy storage contract

Why are trams with energy storage important?

Trams with energy storage are popular for their energy efficiency and reduced operational risk. An effective energy management strategy is optimized to enable a reasonable distribution of demand power among the storage elements, efficient use of energy as well as enhance the service life of the hybrid energy storage system (HESS).

When will a battery-powered tram be available in Romania?

In July 2019, the city of Timisoara in Romania signed a contract with Bozonkaya A.S. to deliver 16 battery-powered trams to enter operation in 2021, when the Rumanian city becomes the European Capital of Culture . In 2018, Bombardier's ‘Talent 3’ catenary/battery train was unveiled to the public.

What makes Flexity trams unique?

The trams combine a unique identity well suited to the operability needs and user experience, built on the extensive Flexity operational history in Melbourne. Designed with passenger safety and comfort in mind, each of the new trams has multi-purpose areas that offer ample space for strollers, bicycles, and wheelchairs.

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.

How much energy does a hybrid storage system use?

The total weight of the hybrid storage system is 1646 kg, resulting in specific energy and power of 11.45 Wh/kg and 226 W/kg, respectively. The storage solution demonstrates effective energy savings and wireless operation capability up to 2.5 km.
