Why are energy storage trams important?

The modern tram system is an essential part of urban public transportation, and it has been developed considerably worldwide in recent years. With the advantages of safety, low cost, and friendliness to the urban landscape, energy storage trams have gradually become an important method to relieve the pressure of public transportation.

What does a battery pack do on a tram?

As the sole power source of the tram, the battery pack can supply power to the traction system and absorb the regenerative braking energy during electric braking to recharge the energy storage system. The traction system mainly consists of the inverter, traction motor, gearbox, and axle.

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 are lithium batteries used in energy storage trams?

Compared with the traditional overhead contact grid or third-rail power supply, energy storage trams equipped with lithium batteries have been developed rapidly because of their advantages of flexible railway laying and high regenerative braking energy utilization.

How are tram travel data collected?

1. The distance, speed, acceleration and altitude data of example tram journeys that covers all the routes and stops was collected, initially on a second by second basis via a dedicated GPS device, with data collection covering both morning (08:00–12:00) and afternoon (14:00–18:00) travel patterns, on three different weekdays in June 2018. 2.
