6 FAQs about [Tram energy storage station overseas]

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.

Can EVs be used as energy storage for the tram network?

Therefore, this research assumes that the tram service provider would provide the EV owners, who allow their EVs to be used as energy storage for the tram network, with incentives (e.g. discounted travel perhaps) to compensate for the extra degradation of the EV battery.

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.

Does the ESS provide its own energy to the tram?

Conversely, if the increase of E reg is less than the reduction of energy from E sub, then the ESS provides its own energy to the tram.

Should rail vehicles have onboard energy storage systems?
