3 FAQs about [Tram wins best energy storage]

Are energy trams better than buses?

The new energy trams have significantly higher passenger capacity than buses, significantly lower investment prices, and lower construction cycle than the metro.

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.

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.
