4 FAQs about [Tram energy storage company dormitory]
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.
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.
