What is a tram with energy storage?

Tram with energy storage is the application of energy storage power supply technology, the vehicle itself is equipped with energy storage equipment as the power source of the whole vehicle.

How energy storage equipment affect the performance of a tram?

The characteristics of the energy storage equipment of the tram, which is the tram power supply system, will largely affect the performance of the whole vehicle. Since there is still a lack of a single energy storage element with high power density and energy density to meet the vehicle operation requirements [ 6, 7 ].

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.

How much energy does a tram use?

The greater the distance between stations, the greater the demand energy. The first interval has the largest distance and maximum energy consumption. If the recovered braking energy is not included, the energy consumption is 7.012 kwh. Fig. 3. DC bus demand energy curve. The tram adopts the power supply mode of catenary free and on-board SESS.
