How does the tram battery energy storage station work

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.

Which energy storage system is best for a tram?

Battery energy storage system with good energy density and power density characteristics is currently the preferred choice for on-board energy storage system. Compared with the current popular pure electric vehicles, the pure battery-driven tram has higher demand for energy and power.

Why is energy storage system on trams important?

The energy storage system on the trams has been convinced to meet the requirements of catenary free tram network for both at home and abroad. This technology improves the technical level of domestic tram development greatly and promotes the development of China’s rail tram industry.

What is the energy storage system of catenary free trams?

On the basis of the research on the energy storage system of catenary free trams, the technology of on-board energy storage, high current charging and discharging and capacity management system has been broken through. The trams with the energy storage system have been assembled and have completed the relative type tests.

What is a pure battery-driven tram?

Compared with the current popular pure electric vehicles, the pure battery-driven tram has higher demand for energy and power. This often requires the battery to be grouped in parallel and series, and then, the battery packs are connected in parallel to improve the battery system capacity.

How does a battery management system work?

In the charging process, the communication between the battery management system and the charger is established by means of wireless communication to ensure the charging control of the battery system. Each battery pack of the on-board battery energy storage system includes 324 series and 4 parallels.
